Lumma Stealer is a fully-featured crimeware solution that’s offered for sale under the malware-as-a-service (MaaS) model, giving a way for cybercriminals to harvest a wide range of information from compromised Windows hosts. In early 2024, the malware operators announced an integration with a Golang-based proxy malware named GhostSocks.
“The addition of a SOCKS5 backconnect feature to existing Lumma infections, or any malware for that matter, is highly lucrative for threat actors,” Infrawatch said.
“By leveraging victims’ internet connections, attackers can bypass geographic restrictions and IP-based integrity checks, particularly those enforced by financial institutions and other high-value targets. This capability significantly increases the probability of success for unauthorized access attempts using credentials harvested via infostealer logs, further enhancing the post-exploitation value of Lumma infections.”
