This blog is reserved for more serious things, and ordinarily I wouldn't spend time on questions like the above. But much as I'd like to spend my time writing about exciting topics, sometimes the world requires a bit of what Brad Delong calls "Intellectual Garbage Pickup," namely: correcting wrong, or mostly-wrong ideas that spread unchecked…

In this post, we analyze a new opportunistic exploitation campaign based on the Log4j vulnerability.

• 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.

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. To follow along, you should have a basic understanding of exploitation, as well as knowledge of C and Python programming, and some familiarity with low-level assembly language. While the topics may be advanced, I’ll do my best to present them smoothly.

Imagine this: an OpenSSH backdoor is discovered, maintainers rush to push out a fixed release package, security researchers trade technical details on mailing lists to analyze the backdoor code. Speculation abounds on the attribution and motives of the attacker, and the tech media pounces on the story. A near miss of epic proportions, a blow to the fabric of trust underlying open source development, a stark reminder of the risks of supply-chain attacks. Equal measures brilliant and devious.
