Credential harvesting is a type of cyber threat that takes advantage of username and password theft in order to exploit stolen login information for a use case. An example of credential harvesting would be attackers stealing usernames and passwords to allow them access to the hacked/stolen accounts, potential access to personal finances, damage to the personal security of others, etc. Having input about credential harvesting, how to identify it and how to prevent being exposed to it can help protect you and your organization.

What is Credential Harvesting?

Credential harvesting is the unauthorized gathering of login credentials, including usernames and passwords. There are a variety of ways attackers try to tempt users into voluntarily revealing this information or install malicious software that obtains some of that information without the user’s knowledge. If credential harvesting is successful, the credentials can be used for identity theft, financial fraud, and unauthorized access to systems.

How Credential Harvesting Works?

In order to stop credential harvesting, you first need to understand how credential harvesting takes place. Attacks of this nature are not immediately obvious and use social engineering, fake interfaces, and tools hidden from view to trick users while quietly capturing their login information. The way these attacks are delivered may differ, but the principle will be the same: to make unauthorized access to valuable accounts and systems. Once you understand how these mechanisms work, you can more readily identify and prevent them earlier in the process.

Attackers use a variety of methods to capture your credentials:

• Phishing Emails: Attackers distribute intentionally misleading emails containing links to fake websites. The fake websites prompt users to enter login information.
• Smishing & Vishing: Smishing is a fraudulent text message scam; Vishing is a fraudulent phone call. provide some summary here.
• Fake Websites: Attackers create fake websites that look legitimate and then prompt users to enter credentials on the fake website.
• Malware: Credential theft runtime malware, like Infostealer or a keylogger, could be placed on a device and used to capture login information.
• Man-in-the-Middle Attacks: The attacker could capture information from the communication between the user and the website.
• Third-Party Breaches: They could steal credentials from known sources like other services and then use those credentials to access additional accounts.

Whether via social engineering or technology, the purpose is to capture login data and exploit it, this is the core credential harvesting definition.

The Role of Malware in Credential Harvesting

Keyloggers

Keyloggers will capture every keystroke a user performs. So, when a user types their username and password, the keylogger will capture that data and send it to the attacker. Keyloggers are typically distributed by phishing emails or through infected downloads. 

Infostealers

Infostealers will scan your machine for saved credentials, such as a password saved in a web browser, email client, or messaging application. Infostealers will copy this data and send it off to the attacker, often in a matter of seconds.

Credential Harvesters

Some malware that harvests credentials are designed to locate passwords and other credentials stored in a device’s memory or internal files. This includes extracting a Windows password, browser login information, saved VPN logs, and more.

Remote Access Trojan (RAT)

Remote Access Trojan can grant attackers full access to a victim’s device and the information contained. They can peer into the screen, transfer files, install other malware, see secure sessions for the purpose of stealing even more information, and all of this is done without a victim’s knowledge. 

Delivery Methods 

There are many ways of delivering malware such as:

• Phishing emails: malicious attachments or links that install malware.
•  Fake Software: A program or update that appears to be legitimate. 
• Compromised website: websites that install malware just for visiting. 

Malware that harvests credentials in a silent and serious way. When malware is working in the background, the victim is often unaware that their credentials are being harvested until they are being used against them.

Common Signs of a Credential Harvesting Attack

Unfamiliar Login Attempts

• Login attempts from unfamiliar devices or locations are alerts for possible unauthorized access attempts.

Several Failed Login Attempts

• Multiple failed logins may indicate someone is attempting to guess passwords or has obtained your credentials illegally. 

Suspicious Account Activity 

• If there has been activity on your account that has changed account settings, password resets, or unknown charges, it may indicate that user account credentials are or have been compromised. 

Phishing Emails 

• Emails that ask you to click on links or request you to access or provide personal information is a common way to harvest credentials.

Security Alerts

• The alerts you receive from security software about potential threats or unauthorized access attempts should not be ignored! 

If you see any of the signs above, please take action to protect your accounts and mitigate further risk of unauthorized access.

Real-World Examples of Credential Harvesting 

Real-life examples provide perspective for the real damage credential harvesting can cause. Credential harvesting attacks can impact more than just individuals; they can disrupt large organizations and eliminate entire industries. By looking at real-life examples, we can see the approaches that attackers can take, the follow-on ramifications, and the importance of proactively dealing with the security risk.

Gaining insight into real events is helpful to demonstrate the consequences of credential harvesting: 

Reddit (2023) 

Attackers can gain access to Reddit’s internal tools via a phishing campaign that targets the employees of the company, ultimately allowing the attackers to gain access to Reddit’s sensitive data.

UPS Canada Smishing Attack (2023) 

Customers received fraudulent text messages fraudulent text messages of UPS–that directed them to a fake site so the attackers could harvest their login credentials.

These cases illustrate the credential harvesting meaning in real-world terms: stolen logins can lead to data breaches, financial loss, and major brand damage.

Legal Context: Compliance and Regulations

In today’s digital world, protecting user credentials is a legal obligation. Worldwide regulations impose requirements on organizations regarding how personal user data is collected, stored, and protected. These laws ensure misuse is prevented, and accountability and user privacy is maintained. With an increasing regulatory landscape, the repercussions of failing to comply could be a costly fine or damage to reputation.

Companies are legally obligated to protect the data of users:

General Data Protection Regulation (GDPR)

A law applicable to businesses that process the data of residents of the EU. The GDPR has strict guidelines that regulate how an organization protects user data; if the organization suffers a data breach, certain actions are required.

California Consumer Privacy Act (CCPA)

Requires organizations to be able to provide fair notice to California residents about their data as well as give residents control of the personal information collected; a major requirement of the CCPA is the right to know and the right to delete.

Health Insurance Portability and Accountability Act (HIPAA)

Sets standards for the protection of sensitive health information of patients in the U.S., and states requirements regarding security of data and notification to the public in the event of a breach.

Failure to comply with these regulations can expose organizations to significant fines and to lawsuits as well.

Preventing Credential Harvesting

Security Awareness Training

Your staff ought to know what phishing may look like and how to practice safe internet procedures and the possible consequences of credential compromise.

Multi-factor Authentication (MFA)

Implementation will add a second authentication factor beyond a username/password, making it that much more difficult for other individuals to access.

Strong Password Policies

Promote strong passwords, ensure they are always unique and complex and are rotated regularly to minimize the risk of compromised credentials.

Password Managers

Assists in generating and storing safe passwords without having to recall each password, encouraging enhanced password habits.

Automatic Software Updates

Maintain up-to-date systems and applications to patch known weaknesses that might be used for credential harvesting.

Anti-Phishing Technologies

Implement software that identifies and blocks phishing, minimizing the possibility of credential compromise through fraudulent email.

Understanding what credential harvesting is? and implementing these steps dramatically reduces your risk.

Emerging Technologies in Detection and Prevention

Artificial Intelligence (AI) and Machine Learning (ML)

Review user behavior looking for signs which suggest that credential theft has taken place, allowing for Mark attack surface reduction as well as proactive threat detection. 

Behavioral Biometrics

Record all actions which can be measured via technology; for example, keystroke patterns or mouse movements are notable patterns, thereby managing and verifying user identity without the need to provide more traditional forms of identification.

Passwordless Authentication

Various authentication and credential forms – most notably biometric authentication and security keys- don’t require passwords at all; thus, credential harvesting is all but stopped in its tracks.

Through these types of technologies, we can help to secure stolen credentials and ultimately overlap as much as possible with crooks trying to steal them.

Responding to a Credential Harvesting Incident

1. Change Passwords Right Away

Change the password for the affected account and any other accounts that use the same credentials to limit any additional unauthorised access.

2. Set up MFA

Where available, use multi-factor authentication (MFA) to provide an extra layer of security to your account. This will provide another hurdle for any unauthorised access using your credentials.

3. Scan for Malware

Use reputable security software to detect and remove any malware from your local device that may have been involved in the theft of your credentials.

4. Inform Relevant Parties

Notify your organisation’s IT department or notify the relevant service providers impacted to start their response.

5. Monitor Accounts

As per step two, you should monitor your online accounts for any unusual activity. Identifying an active or ongoing attack will assist in the response stage.

If acted upon quickly, the damage can be reduced and limit the occurrence of additional unauthorised access.

Conclusion

Credential harvesting is much more than an IT issue. It is a growing menace with actual and catastrophic consequences to individuals, corporations, and organizations. Cybercriminals will keep refining their attacks using phishing, malware, fake websites, and social engineering to covertly collect usernames, passwords, and other sensitive data. When many hackers acquire credentials, they tend to begin with larger breaches which lead to outright theft of money, leak of sensitive data, and reputational harm.

In today’s internet-driven world, it is essential that every user understands credential harvesting meaning, how it works, and how to spot the early indicators. Attackers exploit human behaviour, poor security hygiene, and legacy systems. Thus, with some knowledge and a plan in place, you can disrupt that advantage.

Ultimately, the key point is this: Prevention is more effective and less expensive than response. When you maintain awareness and vigilance, you are not only protecting your personal or business data but you are also minimizing vulnerabilities relative to one of the most prevalent threats today.
