What is Credential Harvesting in Cyber security?
Credential phishing, username harvesting, and password harvesting are all well-known alternative terms used for credential harvesting. In cybersecurity, “Credential harvesting is a type of cyber attack that refers to the illegal collection of user’s login credentials such as usernames, passwords, and user IDs to drive other cyber attacks like account hacking and phishing.”
However, cybercriminals may use social engineering tactics like phishing emails, malicious links, or malware to harvest the user’s credentials as much as possible. Credential harvesting works simply, somewhat similar to other cyberattacks. In fact, attackers craft phishing messages that include phishing links and propagate them to potential targets. Clicking on the phishing link in the received message leads the target toward a fake website. Target may use login details (e.g., username and password) on a malicious website where attackers may observe and collect the user’s credentials.
Credential harvesting may lead to identity theft and unauthorized access to various digital systems or networks. Therefore, Credential harvesting often serves as an initial gateway for social engineering attacks, particularly phishing. In some cases, stolen credentials can also facilitate attacks like tailgating and baiting.
Anyhow, credential harvesting may target any individual or organization and cause long-term damage. Therefore, recognizing credential harvesting is crucial for online or digital security.
Here are the major signals of credential harvesting attempts.
- Unusual account lockouts or multiple password reset requests
- Suspicious emails/messages requesting login details
- Website oddities (faults in URLs and missing HTTPS)
How to Protect Against Credential Harvesting
Any individual or organization can effectively protect against credential harvesting by following the strategies discussed below:
- Security awareness training: Security awareness programs educate users about the mechanism and danger of credential harvesting. Moreover, awareness training also guides users in effectively protecting against credential harvesting.
- Use strong and unique passwords: Secure password practice is a potential strategy to protect from credential harvesting. Strong and complex passwords for social or financial accounts can reduce the possibility of credential harvesting attempts.
- Two-factor authentication (2FA): Enable 2FA as soon as possible. This practice provides an extra layer of security beyond usernames and passwords. Thus, 2FA is also a potential way to reduce the danger of such cyberattacks.
- Antivirus/Anti-malware software: Install reputable and authentic anti-malware software on your devices. These antivirus software can block malicious emails/links and protect devices from downloading malware.
