Progress Telerik security advisories (edit: plural):

• Insecure Deserialization Vulnerability - CVE-2024-6327 (9.9 critical, disclosed 24 July 2024) In Progress Telerik Report Server versions prior to 2024 Q2 (10.1.24.709), a remote code execution attack is possible through an insecure deserialization vulnerability.
• Object Injection Vulnerability - CVE-2024-6096 In Progress Telerik Reporting versions prior to 18.1.24.709, a code execution attack is possible through object injection via an insecure type resolution vulnerability.

No mention of exploitation.

Why you should care about CVE-2024-6327: FIVE Telerik vulnerabilities are known exploited vulnerabilities, TWO specifically called Progress Telerik. One in particular, CVE-2019-18935, is a deserialization of untrusted data vulnerability. This is the same one exploited against the U.S. government last year as noted by CISA on 15 June 2023: Threat Actors Exploit Progress Telerik Vulnerabilities in Multiple U.S. Government IIS Servers. Patch your Teleriks.

Something I've had on my list for quite some time and finally got around to now: updating the HowFuzzilliWorks document: https://github.com/googleprojectzero/fuzzilli/blob/main/Docs/HowFuzzilliWorks.md

Besides a number of smaller changes (e.g. new mutators), the design of the HybridEngine has changed considerably since the document was initially written.

Happy fuzzing!

#TIL that the #IAEA uses something called a „COBRA seal“ to seal relevant objects against manipulation. One type of these seals works by using a multi-core optical cable. When the seal is locked a random number of cores are cut. This creates a unique optical pattern that can be verified simply by shining a light into the cable and can’t be recreated.

Do I know anyone with a mail address on a mail server managed by barracuda networks who would help me with something? I'd like to test a few things (just sending you a few test mails and see if they arrive).

Wild, true story from the security awareness and training company KnowBe4 that details how they inadvertently hired a North Korean hacker who was posing as a Western tech worker.

Kudos to them for publishing this. If it can happen to a security awareness company, it can happen to anyone (full disclosure: they've been an advertiser on my site for ages).

Was ILOVEYOU worse than CrowdStrike?

https://en.m.wikipedia.org/wiki/ILOVEYOU

Looks like more hosts were affected by ILOVEYOU (45 million in the first 24 hours) ... but the damage was somewhat more random because files were overwritten.

And now that there is a well-known CrowdStrike recovery procedure, as long as you follow it, you're okay -- but if you didn't have good backups, files overwritten by ILOVEYOU were unrecoverable.

Any event that makes the front page of a news outlet will be used as a phishing lure.

Any “threat intelligence” that alerts you to this is next to useless.

Email received a few days ago: "We need to know which version of SSH is installed on the server, as we want to ensure it is not vulnerable to external attacks." My response: "Don’t worry, SSH is accessible ONLY via VPN, and I am the only one with access to that VPN—activated only when needed—so there is no way for there to be any issues, regardless of the version used."

Email received this morning: "We’re not interested; you must provide the SSH version installed and, if it's not the latest, ensure us of the update date."
My response: "Sorry, could you explain the rationale? SSH is not exposed, it’s not listening on any public IP."
Their reply: "Provide the version."
My response: "OpenSSH_9.7, LibreSSL 3.9.0, on OpenBSD."
Their reply: "This is not considered secure. It must be OpenSSH_9.2p1 Debian-2+deb12u3."
My response: "It’s not Debian; it’s OpenBSD."
Their reply: "So the systems are insecure."

And they claim to be a cybersecurity company...
