How credentials are getting breached?

Understanding Infostealers

Infostealers are a class of malware designed to covertly extract sensitive information from compromised systems. This includes credentials, browser cookies, autofill data, cryptocurrency wallets, and more. Once harvested, this data is often sold on underground forums or used directly in cyberattacks such as account takeovers, ransomware deployments, and corporate espionage. Hudson Rock's research indicates that infostealer infections have surged by 6000% since 2018, positioning them as a primary initial attack vector for threat actors.

Infostealers are often distributed through phishing emails, malicious advertisements, and compromised software downloads. A notable tactic involves embedding infostealers in seemingly legitimate software or documents, tricking users into executing the malware. Cybercriminals frequently target content creators by offering fake partnership opportunities, leading to infostealer infections and subsequent account takeovers.

Mitigation Strategies

To combat the threat of infostealers, organisations should implement robust cybersecurity measures:

• Multi-Factor Authentication (MFA): Enforce MFA across all user accounts to add an extra layer of security.

• Employee Education: Regularly train staff to recognise phishing attempts and suspicious downloads.

• Endpoint Protection: Deploy advanced endpoint detection and response solutions to identify and neutralise threats promptly.

• Regular Updates: Ensure all systems and software are up-to-date with the latest security patches.

The escalation of infostealer malware poses a significant threat to organisations worldwide. By understanding the tactics employed by cybercriminals and implementing comprehensive security measures, businesses can better protect their assets and maintain operational integrity. Leveraging threat intelligence solutions and fostering a culture of cybersecurity awareness are pivotal steps in mitigating these evolving risks.
