Over the past year, Cyble Research Labs has noticed extensive usage of “Stealer” malware by initial access brokers to compromise victims. These initial access brokers can trade these credentials with other criminal groups, launching targeted attacks on specific organizations. These are designed to steal user credentials such as usernames, passwords, and cookies and send them to a server under the attacker’s control. The stolen information is then aggregated and sold to other interested criminal groups that can abuse this access for espionage, data theft, or even ransomware attacks. This report reveals the prevalence of stealer malware campaigns and evolving models.

Stealers or “info stealers” are malware variants belonging to the Trojan family. These are designed to steal user credentials such as usernames, passwords, and cookies and send them to a server under the attacker’s control. These attackers – also called “initial access brokers” – tend to use phishing campaigns to distribute such stealer malware and gather user credentials, system information, and even screenshots or data from their victims. The stolen information is then aggregated and sold to other interested criminal groups that can abuse this access for espionage, data theft, or even ransomware attacks.

Cyble has analyzed 50+ Stealer variants that are in circulation and are being widely used in various threat campaigns globally.
