Credential harvesting is a cyberattack technique in which adversaries steal user login credentials (usernames, passwords, etc.) for unauthorized access. Common methods include social engineering scams like phishing emails or smishing texts, info-stealing malware, and even brute-force attempts leveraging leaked passwords. Because stolen credentials let attackers impersonate legitimate users, credential harvesting attacks can bypass traditional security measures and lead to major breaches. Roughly 80% of data breaches involve stolen or weak credentials ( 80% of data breaches still involve stolen credentials. – Plurilock ), so detecting and mitigating these attacks is critical for protecting organizations.
Key Takeaways
Credential harvesting is the theft of login credentials (usernames, passwords, etc.) via tactics like phishing scams, fake websites, malware (keyloggers/infostealers), or exploiting weak passwords . Attackers use the stolen credentials to gain unauthorized access to accounts and systems. Stolen credentials enable stealthy breaches: With valid usernames and passwords in hand, attackers can log in as legitimate users – making the intrusion hard to detect with traditional security tools. Once inside, they can escalate privileges and move laterally through a network to steal data or deploy ransomware. Common harvesting techniques: Spear phishing emails (or SMS “smishing”) that lure users to fake login pages , credential-stealing malware (keyloggers, infostealers) that capture keystrokes or saved passwords, and credential stuffing (using lists of leaked passwords in bulk) are all prevalent attack methods. Attackers often automate these techniques using bots and scripts to test stolen credentials at scale. Detection is challenging but possible: Traditional defenses struggle to flag credential-based attacks, so proactive detection is key. Solutions like sandbox analysis can safely execute suspicious links or attachments to observe credential theft behavior. AI-driven monitoring of login patterns and user behavior can spot anomalies (e.g. unusual login locations or rapid-fire login attempts) indicating credential abuse. Strong defenses can mitigate attacks: Implementing multi-factor authentication (MFA) stops most credential phishing cold – a stolen password alone isn’t enough to break in. Enforcing strong, unique passwords (with the help of managers) and regular security awareness training reduces the chances of credential compromise. Layered defenses (email filtering, endpoint security) further help prevent credential harvesting attempts. Business impact is severe: Credential harvesting often leads to costly breaches, fraud, and downtime. Once inside, attackers can empty financial accounts or commit fraud, damage a company’s reputation by leaking data, and even cause regulatory fines for data breaches. High-profile incidents like the Colonial Pipeline ransomware attack began with one stolen password (on a VPN with no MFA) ( One password allowed hackers to disrupt Colonial Pipeline, CEO tells senators | Reuters ), underscoring how a simple credential lapse can escalate into a crisis.
What is Credential Harvesting, and How Does It Work? Credential harvesting refers to any attack where cybercriminals collect legitimate user credentials (usually usernames and passwords) without authorization . It’s often the first phase of a more significant breach: attackers steal login credentials, then use those valid credentials to infiltrate systems and carry out further malicious activities. By logging in with a real user’s credentials, an adversary can impersonate that user and appear legitimate, which makes detection difficult.
How attackers obtain credentials: In practice, credential harvesting can happen through various means. Phishing is one of the most common: an attacker sends a deceptive email or message that tricks the victim into entering their username and password on a bogus login page or form. For example, they might impersonate a well-known service (email provider, bank, SaaS app) and provide a link to a site that looks real but is designed purely to capture credentials. Malware is another major avenue – attackers may use keyloggers or infostealer malware that silently records keystrokes or extracts saved passwords once run on a victim’s machine. There are also cases of attackers exploiting vulnerable websites or using man-in-the-middle tricks (intercepting network traffic) to grab credentials in transit. In some scenarios, criminals simply buy stolen credential dumps from previous data breaches on the dark web, or use automated tools to test common passwords against many accounts (brute force).
Attack lifecycle: After harvesting credentials, attackers typically test them to gain access. Upon a successful login, they have a foothold inside the target system or network. From here, they often attempt to escalate privileges (for instance, using the stolen user account to access admin functions or more sensitive systems). They may also use the initial access to conduct reconnaissance and then move laterally – accessing other servers, cloud services, or email accounts to which the compromised user has rights. With broader access, the attacker can engage in various malicious actions: exfiltrating sensitive data (customer records, intellectual property), planting malware or backdoors, or even deploying ransomware. Stolen credentials can also be leveraged for identity fraud (using someone’s account to commit fraud or send phishing messages internally) or sold to other threat actors. The end goal might be immediate financial gain (stealing money or cryptocurrency from accounts) or positioning for a more significant breach. Often, credential harvesting is just step one of a multi-stage attack that can culminate in a full-blown data breach, business email compromise, or IT disruption .
Importantly, credential harvesting can go undetected for some time. Unlike malware that might crash systems or generate obvious alerts, using valid credentials can “fly under the radar.” The attacker essentially piggybacks on the standard authentication process. This is why organizations prioritize preventing credential theft in the first place and monitoring for subtle signs of unauthorized access.
Common Credential Harvesting Techniques Attackers have developed numerous techniques to steal credentials. Here are some of the most prevalent methods:
Phishing-Based Credential Harvesting Phishing Emails: Phishing is the art of tricking users into divulging information by posing as a trusted entity. In credential harvesting, phishing often involves emails impersonating legitimate companies or IT support. These emails typically urge the target to click a link – for example, to “reset your password” or “verify your account” – which leads to a fake login page. The fake page is crafted to look identical to a real login portal (such as Office 365, Google Workspace, banking sites, etc.) so the victim doesn’t suspect anything. When the user enters their username and password, the credentials are captured by the attacker. Mass phishing campaigns cast a wide net (thousands of generic “your account is locked” emails), while spear phishing targets specific individuals or organizations with tailored messages (often referencing known colleagues or business details to appear convincing). Smishing is a similar ploy via SMS text messages instead of email – users receive a text with a link to a bogus login site or a prompt to reply with account info.
Fake login pages that closely mimic legitimate sites are used to harvest credentials from unwitting users. The image below shows an example of a spoofed login portal impersonating a school system, with telltale signs like an odd URL marking it as fraudulent. In real attacks, such counterfeit pages may use lookalike domain names (e.g. micros0ft-online.com instead of microsoft.com ) and stolen branding to appear authentic. Victims who log in simply hand their credentials over to the attacker’s database.
Phishing-based credential harvesting isn’t limited to websites. Attackers may also use email attachments (e.g., an HTML file or PDF that contains an embedded login form or a script) to locally prompt users for credentials. Some phishing emails carry malware attachments that, if opened, install keyloggers – blurring the line into malware-based theft. Additionally, adversaries exploit social engineering via phone calls (voice phishing or “vishing”) or direct messages on collaboration platforms, all to gain the target’s trust and persuade them to reveal passwords or one-time passcodes. The core idea is the same, no matter the delivery method: trick the user into voluntarily providing their login secrets to the wrong party.
Malware-Based Credential Theft Not all credential harvesting relies on human deception; malware can do the job automatically once it infects a system. Keyloggers are one classic example: malicious programs that record every keystroke a user types, then transmit the captured data (which often includes usernames and passwords typed into login forms) back to the attacker. Similarly, infostealer malware is designed to scan an infected system for stored credentials. Many users save passwords in their web browsers, email clients, or FTP tools – infostealers can extract those saved credentials, session cookies, and other authentication tokens. A well-known modern breed of infostealer (like RedLine, Raccoon, or Vidar) can quietly collect passwords from browsers, VPN clients, messaging apps, and even crypto wallets, sending that loot to the attacker’s server.
Attackers deliver credential-stealing malware through various means. Email attachments with malicious macros or executables are a common vector (masquerading as invoices, resumes, etc.). Drive-by downloads and exploit kits on compromised websites are another: if a user visits a hacked or malicious site, it can exploit browser vulnerabilities to drop a keylogger in the background. Even legitimate websites can be turned against users if attackers inject malicious scripts. For instance, the infamous Magecart attacks insert code into e-commerce checkout pages to skim credit card numbers. That concept extends to credentials: an attacker who breaches a website might implant a phishing kit or malicious plugin that records login attempts (effectively turning the real website into a credential harvester). There have been cases of browser extensions and mobile apps that hide trojan functionality to steal credentials as well.
Once malware is active on a machine, it may also open backdoors for further control (like a Remote Access Trojan, RAT). A RAT allows the attacker to remotely manipulate the system, including grabbing password hashes from memory or using system tools to dump credentials (for example, using Mimikatz to dump Windows credentials). This moves beyond simple harvesting into broader compromise, starting with that initial malware execution. Security teams often first detect these attacks by spotting suspicious network traffic (malware sending data) or by analyzing malware in a sandbox environment to see if it tries to hook keyboard inputs or read credential stores.
Brute-Force and Credential Stuffing Attacks Not all credential theft requires tricking the user or malware infection – sometimes attackers can obtain credentials by systematically guessing or replaying them. Brute-force attacks involve trying many password combinations against a user’s account until the correct one is found. Simple brute-force (iterating through combinations like a safe-cracker) is less common nowadays for well-secured systems because account lockout policies and the vast keyspace size for strong passwords make it impractical. However, attackers refine this with techniques like password spraying – testing a small set of the most common passwords (like “Password123!” or “Welcome2023”) across many different accounts to avoid triggering lockouts on any single account. Unfortunately, due to weak password choices, this tactic does succeed at times.
A more efficient approach for attackers is credential stuffing . The attacker takes advantage of the millions of username/password pairs exposed in past data breaches. Users often reuse passwords across multiple sites; credential stuffing targets this weakness. Attackers use automated tools and botnets to attempt logins on one service using credentials leaked from another service. For example, if an attacker knows that john.doe@example.com with password “qwerty99” was leaked from an old forum breach, they might try those credentials on banking sites, corporate VPNs, or email accounts. With enough volume (and sadly, password reuse being so common), they will hit valid logins on some sites. Tools for credential stuffing are widely available, and they can attempt thousands of logins per minute, often cycling through proxies or stolen IP addresses to avoid IP-based throttling. This automated, bot-driven attack can bombard an organization’s login systems with attempts. From the defender’s side, it may show up as a surge in failed logins or account lockouts. A sudden wave of account lockouts in an enterprise is a strong sign that someone is trying credential stuffing or brute force with leaked credentials.
Credential stuffing essentially “harvests” working credentials from the attacker’s perspective – they start with a trove of potential credentials and end up with a smaller set of credentials that successfully authenticate on other targets. It’s a numbers game. This is why large web services and enterprises monitor for credential stuffing and often participate in breach notification services (to proactively reset any passwords exposed in third-party breaches). Attackers will even use bots to test credential validity, then package the verified credentials for sale or use in deeper attacks. For example, if an adversary gets a VPN login to a corporate network via stuffing, they can access internal systems as that user.
How to Detect and Identify Credential Harvesting Attacks Detecting credential harvesting attacks is notoriously challenging because, in many cases, the attacker is leveraging what appear to be valid credentials. Traditional security tools like firewalls and antivirus are good at catching malware signatures or known bad domains. Still, they might not blink when an attacker logs in with a legitimate username and password. As a result, organizations need to use behavioral detection and advanced analysis to spot the subtle red flags of credential-based attacks.
Why do conventional defenses struggle here? Imagine an attacker phishing an employee’s VPN credentials and logging in remotely. To the VPN, that login might look like a normal (if slightly suspicious location) user login – no malware involved, no exploits, just a username/password combination. Similarly, if malware on a device is quietly siphoning passwords, it may not exhibit obvious malicious behavior that triggers endpoint protection. Because of this, detection of credential harvesting often relies on correlating context and anomalies:
Unusual Authentication Patterns: One key detection strategy is monitoring authentication logs for anomalies. This includes identifying logins from unfamiliar IP addresses or locations (e.g., an employee account logging in from a country where the company doesn’t operate), and noticing if one account attempts logins to many services in a short time (possibly indicating an attacker testing access broadly). Multiple failed login attempts followed by a success could indicate a brute-force or credential-stuffing attempt. Likewise, a spike in account lockouts could mean an automated tool attempts many passwords on those accounts, triggering protective lockouts. Implementing user and entity behavior analytics (UEBA) can significantly help. These systems learn standard login patterns for each user (times, locations, devices) and alert on deviations that match known threat patterns of credential misuse.
Sandbox Analysis of Phishing Content: Since phishing is a significant delivery method for credential harvesters, using a sandbox to analyze suspected phishing emails and links can catch the threat before credentials are stolen. For instance, if an email contains a link to a login page, a sandbox tool like VMRay DeepResponse can automatically click that link in a controlled virtual environment and observe what happens. If the page is a phony login, the sandbox might detect that entering dummy credentials causes those credentials to be sent to an unknown server – a strong indicator of a credential harvester at work. Similarly, sandboxing suspicious attachments (HTML files, documents with macros) can reveal hidden login forms or keylogger behavior without risking a real user’s data. This kind of dynamic analysis is crucial for detecting novel phishing kits or malware strains that signature-based scanners don’t yet recognize. Advanced sandboxes will not only flag the malicious phishing page but also capture indicators like the phishing site’s URL, the content it displays, and any credentials it tried to collect, which security teams can use to block that site and warn users.
Alert Validation and AI-Based Behavioral Analysis: Modern security operations centers are inundated with alerts, and distinguishing benign anomalies from genuine credential attacks is difficult. This is where AI-driven solutions and threat intelligence come into play. For example, if an alert fires that an account logged in from a new city, context is everything – was the user traveling or working remotely, or could this be an attacker? AI-based alert validation systems ingest data from multiple sources – VPN logs, SaaS logs, threat intel feeds about known bad IPs, etc. – and use machine learning to assess the likelihood that a given login is malicious. These systems look at things like: Is the IP address associated with previous attacks or TOR exit nodes? Is the login happening at an odd hour relative to the user’s normal activity? Is there related activity (like data downloads or changes to the account profile) that suggests a breach? By correlating these factors, behavioral analysis tools can reduce false positives and surface real credential compromise incidents that would otherwise go unnoticed. Threat intelligence is also vital; if intel sources report a new phishing campaign targeting your industry, your SOC can heighten monitoring for any signs of that campaign (like emails with certain subjects or traffic to the phishing domains).
Network Traffic Monitoring: Many credential harvesters eventually have to send stolen data out or trigger unusual internal requests. For instance, a keylogger will send captured keystrokes to a remote server – attentive network monitoring might catch an endpoint making POST requests to an obscure URL regularly. Similarly, an attacker who has logged in might perform actions that stand out: querying an internal LDAP for user lists, accessing sensitive files they have never used before, or connecting to systems that the actual user typically doesn’t. Monitoring network traffic for these anomalies can tip off incident responders. Another sign is detecting tools or commands associated with credential dumping (like if a workstation suddenly starts reaching out to the domain controller in a manner consistent with attempting to dump password hashes). Even encrypted traffic can raise suspicion if a user’s machine starts beaconing to an IP address that is a known malware C2 (command-and-control) server – maybe indicating an infostealer exfiltrating data. Specialized bot detection systems can also identify patterns of credential stuffing in web traffic – for example, dozens of login attempts per second with different credentials, coming from various IPs but with a clear pattern, strongly signal a bot-driven credential testing attack. Solutions like web application firewalls (WAFs) or anti-automation services use behavioral tells (like mouse movements, keystroke timing, etc., or IP reputation) to differentiate human logins from bot-driven credential stuffing, and then block or throttle suspicious login attempts .
In summary, detecting credential harvesting requires technical analysis and contextual awareness . No single indicator is foolproof – security teams must layer these detection methods. Many organizations also employ deception technology (like fake credentials or honeytokens) to lure attackers and set off alarms when those dummy credentials are used. For example, planting a fake admin password in an accessible file can act as a canary; if someone tries to use it, you know a credential harvester is in play. The overarching theme is to assume that some credentials will be compromised and to have monitoring in place to catch the misuse quickly before the attackers can do serious damage. (For additional insights on advanced detection of evolving phishing techniques, see VMRay’s December 2024 Detection Highlights, which discusses catching attacks that use tricks like malicious SVG images to harvest credentials.)
Preventing and Mitigating Credential Harvesting Attacks Preventing credential harvesting is far preferable to detecting it after the fact. A multi-layered defense strategy can significantly reduce the risk of stolen or abused credentials. Key best practices include:
Enable Multi-Factor Authentication (MFA) Everywhere: MFA is one of the most effective measures against credential-based attacks. Even if attackers phish or steal a password, they cannot log in without the second factor (such as a one-time code or mobile app approval) . This blocks the vast majority of opportunistic attacks – for example, an attacker might have an employee’s VPN password, but if the VPN requires a phone approval or hardware token, the password alone is useless. Enforcing MFA on all remote accesses, email accounts, and high-value systems is essential. Modern authentication apps (like Microsoft Authenticator or Duo) make it relatively easy for users to comply. Administrators should also consider using risk-based MFA policies (e.g., constantly challenge if login is from a new device or location). Keep in mind attackers may attempt MFA fatigue techniques (bombarding a user with push requests, hoping they’ll accept one); mitigating that involves user education and throttling push attempts. Overall, MFA adds an essential fail-safe that neutralizes stolen credentials in most cases.
Enforce Strong Password Policies (and Use Password Managers): Weak or reused passwords make an attacker’s job much easier. Organizations should implement policies that require complex, unique passwords for each account and, ideally, a reasonable rotation schedule. Users should be encouraged (or provisioned with) password manager software to handle their passwords – this allows them to have a different 16+ character password for every service without memorization. Password managers also reduce the chance users will resort to writing passwords down or reusing corporate credentials on personal sites. It’s also wise to check new passwords against databases of known leaked passwords (many directory systems and SSO platforms can do this) to prevent employees from using passwords that attackers already have. While forcing periodic password changes has pros and cons, at minimum, any password suspected to be compromised should be changed immediately. Account lockout and throttling policies should be in place to thwart brute-force attempts (e.g., lock an account after five failed tries and alert IT). Additionally, disable or tightly monitor old accounts – an unused account with a weak password a is low-hanging fruit for attackers.
Security Awareness Training and Phishing Simulations: Technology alone isn’t enough – users are the first line of defense against phishing and social engineering. Regular security awareness training educates employees on how to spot phishing emails, suspicious text messages, and other tricks used in credential harvesting. Training should cover the common signs of phishing (poor grammar, urgent demands, mismatched URLs, etc.) and reinforce a culture of healthy skepticism (e.g., “verify before you click”). Many organizations run phishing simulation campaigns – sending fake phishing emails to employees to test and train their responses. This reinforces learning and gives security teams metrics on who might need additional coaching. Users should be trained to report suspected phishing immediately; an early report can enable the security team to warn others or take down malicious sites quickly. It’s also worth training staff on the dangers of reusing corporate passwords on other sites and the importance of not entering credentials into any page that was reached via an email link (instead, they should navigate to the official site manually).
Secure Email Gateways and Web Filtering: Because phishing is a primary vector, investing in good email security can drastically reduce risk. Modern secure email gateway (SEG) solutions and cloud email security add-ons use URL rewriting, attachment sandboxing, and AI to detect phishing emails and either block them or warn the recipient. These tools can defang malicious links by rewriting them through a scanning service that blocks known phishing sites or detonates unknown ones in a sandbox when clicked. Likewise, maintain up-to-date antivirus/endpoint protection on all systems to catch known credential-stealing malware before it executes. Endpoint detection and response (EDR) tools can spot suspicious behavior, such as a process trying to access password stores or injecting it into browser processes (activities typical of infostealers). On the network side, implement web filtering/DNS filtering so that if a user does click a phishing link, the request to the malicious domain can be blocked or sinkhole. Many credential harvester pages use odd domain names – maintaining threat intel feeds of phishing URLs and feeding those into web filters can preemptively stop users from even reaching the phony login page.
Least Privilege and Account Monitoring: Mitigation also involves limiting the damage if an account is compromised. Ensure users have only the access necessary for their role (principle of least privilege) – an attacker who steals a low-level user’s credentials shouldn’t be able to access crown jewel systems without additional barriers. Admin and privileged accounts should be extra protected (MFA, maybe hardware security keys, and closely monitored). Implementing conditional access policies can also help (for example, block login from countries where you don’t do business). Regularly review logs for successful logins by dormant accounts or after hours. Some organizations even use fake admin accounts as honeytokens – any activity on those triggers an alert because no one should be using them. Restricting and watching account usage in this way can catch misuse quickly or prevent an attacker from easily pivoting through an environment with one set of credentials.
In short, prevention comes down to making it hard to steal credentials and limiting their usefulness . That means locking down how attackers harvest (phishing and malware – via training and technical email/web controls) and implementing fail-safes like MFA so that they can’t be readily abused even if credentials are compromised. Combining user awareness, strong authentication, and intelligent monitoring, a defense-in-depth approach offers the best protection against credential harvesting attacks.
Business Impact of Credential Harvesting Attacks Attacks leveraging stolen credentials can have devastating consequences for businesses. When an adversary successfully harvests credentials and breaches an organization, the fallout typically occurs on multiple fronts:
Financial Losses and Fraud: Compromised credentials can lead directly to financial theft. In the case of consumer accounts, attackers may siphon funds (e.g., fraudulent wire transfers from a bank account). For enterprises, an intruder with internal access might commit financial fraud (such as creating bogus invoices or diverting payroll). Beyond direct theft, organizations incur incident response costs – investigating the breach, hiring forensic experts, and remediating affected systems can be extremely expensive. If customer data or payment info is stolen via credential compromise, the business may have to cover credit monitoring services for victims, legal fees, and possibly reimburse fraudulent charges. As an example, when attackers breached the network of a major U.S. fuel pipeline company using a stolen VPN password, the company had to pay a multi-million dollar ransom to restore operations , on top of the revenue lost during the shutdown. Even when the ransom isn’t involved, such incidents’ downtime and recovery process (restoring backups, eradicating malware, etc.) rack up significant labor and infrastructure costs.
Operational Disruption: Credential-based attacks can escalate into scenarios that cripple business operations. Once inside, an attacker might deploy ransomware or sabotage systems. An attacker can lock everyone out or take servers offline if an administrator account is compromised. Even without deliberate sabotage, a swift response often requires taking systems down temporarily. For instance, if email administrator credentials are stolen, email services might be suspended while the breach is contained, impacting day-to-day work. The Colonial Pipeline incident in 2021 is a high-profile example – a single stolen credential (with no MFA protection) allowed attackers to infiltrate and eventually trigger a shutdown of fuel distribution for days. Similarly, in February 2023, attackers who phished a Reddit employee’s credentials could access internal documents, source code, and business systems, threatening to leak 80 GB of data unless a ransom was paid. Reddit had to mobilize incident response and deal with the potential of data exposure, causing significant internal disruption. Such incidents show how credential theft can lead to ransomware attacks, data extortion, or prolonged outages interrupting an organization’s services or production.
Reputational Damage: A breach rooted in stolen credentials can erode customer and partner trust. When news breaks that a company was compromised because an attacker logged in with valid credentials, stakeholders may question its security maturity (“Were they not enforcing MFA? How did no one notice?”). Publicized breaches often lead to loss of business as customers take their data elsewhere, especially if personal or sensitive information is accessed. The brand damage can linger for years; it’s hard to quantify how many potential customers shy away after hearing of a breach. Additionally, employees may feel violated or lose confidence in their employer’s security if their own accounts are misused. Rebuilding reputation requires transparency, strong corrective actions, and time. Some companies never fully recover their market standing after a major credential-related breach.
Legal and Regulatory Consequences: If the credential harvesting attack results in a data breach involving personal information, companies could face regulatory penalties under laws such as GDPR, CCPA, HIPAA, or other data protection regulations. Regulators have little patience for breaches that could have been prevented with basic security hygiene (like MFA or awareness training). Fines can range into the millions for exposing customer data. There’s also the prospect of lawsuits – victims (whether consumers or business clients) might sue for damages if their data was stolen via the breach. Even if a company has cyber insurance, a credential-related breach can drive up future premiums or face coverage challenges if negligence (like not addressing known vulnerabilities or ignoring security best practices) is found. Beyond the immediate technical crisis, there is a long trail of compliance and legal headaches that follow a credential compromise incident.
Credential harvesting attacks span all industries , but specific sectors face higher risks. Financial services, for example, are a prime target because financial accounts and data are inherently valuable. Attackers also target healthcare (for patient records that can be used in identity theft or insurance fraud) and the public sector. Any organization with a large user base of logins (think social media, e-commerce) is continuously bombarded by credential stuffing using the billions of leaked credentials in circulation.
The broad impact of these attacks reinforces why organizations must take credential harvesting seriously. A single stolen password can become the thread that, when pulled, unravels an entire cybersecurity program. The good news is that many credential-related breaches are preventable with today’s technology and best practices – as outlined above, measures like MFA, user training, and vigilant monitoring can stop most of these attacks before they gain a foothold.
Conclusion Credential harvesting is one of the most prevalent threats in cybersecurity today, underpinning everything from targeted breaches to large-scale fraud campaigns. As we’ve discussed, attackers employ deceptive phishing lures, stealthy malware, and automated bot attacks to steal credentials, then leverage those credentials to impersonate users and infiltrate organizations. The key to defending against this threat is a combination of proactive measures – strong authentication (MFA), solid password hygiene, user education – and advanced detection capabilities that can identify suspicious behavior when an attacker does slip through.
Cybersecurity professionals (malware analysts, incident responders, and threat intel analysts alike) must stay vigilant and continuously improve defenses in this cat-and-mouse game. That means routinely testing your organization’s exposure (through phishing simulations and credential leak monitoring), and investing in tools that provide deep insight into threats.
