Just noticed CVE-2025-1829 an RCE in the mtkhnatEnable parameter of /cgi-bin/cstecgi.cgi on TOTOLINK devices being actively exploited.
Exploitation started since 23/03 though which is ~3 weeks after the vuln became public?
Kunai Sandbox is now live!
Curious about Kunai? Want to analyze Linux malware logs? Or share malware analysis to build detection rules? Kunai Sandbox has you covered! 
Check out what Kunai can do:
Explore Kunai's log structure without running it locally Analyze logs generated by Linux malware Share malware analysis with others to build detection rules
See an example analysis of the perfctl #linux #malware: https://sandbox.kunai.rocks/analysis/59edbf8c-41b7-4144-97e0-9b0571446c02
"The remote endpoints it attempted to contact included several TryCloudflare domains as well as direct IP addresses.
The logic would rotate through the various servers until an online host was found. The malware in this case took 15 minutes to establish a successful connection to an online endpoint at hxxp://bristol-weed-martin-know[.]trycloudflare[.]com/init1234."
The above is from a recent Private Threat Brief: "Interlock-Linked Threat Actor Gains Access via Fake Teams ClickFix Lure"

Only one week left to register for our next Cyberside Chats Live event! Join us June 11th to discuss what happens when an AI refuses to shut down—or worse, starts blackmailing users to stay online?
These aren’t science fiction scenarios. We’ll dig into two real-world incidents, including a case where OpenAI’s newest model bypassed shutdown scripts and another where Anthropic’s Claude Opus 4 generated blackmail threats in an alarming display of self-preservation.
Join us as we unpack:
What “high-agency behavior” means in cutting-edge AI How API access can expose unpredictable and dangerous model actions Why these findings matter now for security teams What it all means for incident response and digital trust
Stick around for a live Q&A with LMG Security’s experts @sherridavidoff and @MDurrin. This session will challenge the way you think about AI risk!

New Blog Post: Kunai vs io_uring (https://why.kunai.rocks/blog/kunai-vs-io_uring)
Ever wondered how io_uring revolutionizes I/O operations in the Linux kernel? Inspired by Armo's blog post (https://www.armosec.io/blog/io_uring-rootkit-bypasses-linux-security/) about a PoC rootkit using io_uring, we explored this feature's security implications and how tools like Kunai can monitor these operations.
Key Takeaways:
io_uring boosts I/O performance by reducing system call overhead and enabling asynchronous operations Security tools struggle to monitor io_uring due to its unique handling of operations Kunai now provides visibility into io_uring operations, though blocking malicious activities remains challenging Recent kernel versions have introduced auditing and security controls for io_uring, but these are still limited
Remembering the forensics and accident reconstruction experts testifying in the Karen Read trial is going to run 24/7 in my head if I ever have to testify again.
"Answer the question posed"
"Do not offer additional response"
"I don't know is a full answer"
"Do not be arrogant, seriously, don't"
Mini Digital Forensic Diaries story: got sent to a university in London to investigate a case where a student, who bragged of hacker prowess openly, was suspected of introducing malware to a machine and stealing a lecturers password.
“We don’t know how, but we know they logged into the account, and sent emails - and this is the only machine the lecturer uses,” came the brief.
Imaged the machine suspected of being targeted.
While giving the lecturer their laptop back post imaging I observed, via projector, the lecturer entering in their password to the username field on the login screen.
“Whoops, I’m always doing that - at least this time it wasn’t in front of the students,” they said.
Sure enough, there was no evidence of anything untoward on the laptop, but I had a good theory as to what may have occurred.
