Hunting for Prey

An email or message is sent to a user whouses the Google Authentication App to update to the latest version, users aredirected to the download page and end up installing two malware. At this point, the fish has taken the bait, and the two malicious software:  Latrodectus and ACR Stealer have been installed. Latrodectus is a downloader that executes commands from a Command and Control (C&C) server. This enables attackers to remotely control the infected device, potentially leading to further malicious activities.

Onthe other hand, ACR Stealer utilizes a technique called Dead Drop Resolver to obscure its C&C server details. This makes it challenging for cybersecurity experts to trace and mitigate the threat.
