BlackSuit Ransomware
- In December 2023, we observed an intrusion that started with the execution of a Cobalt Strike beacon and ended in the deployment of BlackSuit ransomware. The threat actor leveraged various tools, including Sharphound, Rubeus, SystemBC, Get-DataInfo.ps1, Cobalt Strike, and ADFind, along with built-in system tools. Command and control traffic was proxied through CloudFlare to conceal their Cobalt Strike server. Fifteen days after initial access, BlackSuit ransomware was deployed by copying files over SMB to admin shares and executing them through RDP sessions. Three rules were added to our private ruleset related to this case.
MacOS X Malware Development
In today’s post, We’ll explore the process of designing and developing malware for macOS, which is a Unix-based operating system. We’ll use a classic approach to understanding Apple’s internals.

Unmasking Styx Stealer: How a Hacker's Slip Led to an Intelligence Treasure Trove - Check Point Research
- Check Point Research (CPR) recently uncovered Styx Stealer, a new malware capable of stealing browser data, instant messenger sessions from Telegram and Discord, and cryptocurrency. Even though it only recently appeared, it has already been noticed in attacks, including those targeting our customers. The developer of Styx Stealer was found to be linked to one of Agent Tesla threat actors, Fucosreal, who was involved in a spam campaign also targeting our customers. During the debugging of Styx Stealer, the developer made a fatal error and leaked data from his computer, which allowed CPR to obtain a large amount of intelligence, including the number of clients, profit information, nicknames, phone numbers, and email addresses, as well as similar data about the actor behind the Agent Tesla campaign.
