Ivanti and Fortinet have unpatched vulnerabilities in their VPN products!
Akamai, in their blog post Living off the VPN — Exploring VPN Post-Exploitation Techniques, talk about techniques that can be used by threat actors after compromising a VPN server to further escalate their intrusion. The key takeaway is that the vulnerability disclosure was published 133 days after initial notification to Ivanti and Fortinet:
Fortinet informed us that after additional consideration, they decided to not fix the custom encryption key bypass as it “does not cross a security boundary”
If the original Ivanti Connect Secure exploited zero-day fiasco hasn't scared you off of their products, this is your wakeup call. As @cadey would say: "No way to prevent this" say users of only VPN where this regularly happens

Another year, another Microsoft Most Valuable Researcher for me. This year, it has a bittersweet taste though.
Let’s kick off with the sweet part.
I’m quite happy with my consistency and findings. My record for 2024:
- 10x Exchange
- 2x SharePoint
- 1x .NET/VS
Multiple RCEs included.
I have also already reported several vulns for 2025, and I’m happy with the technical level of the findings. Not necessarily with the impact, but you don’t always get RCE;). I’m especially happy with the fact that I’m doing some risky deep dives, and sometimes it pays off.
I’m also happy with some recent research. I’ve been abusing unknown attack surfaces and I had some success with that (even though I was not familiar with the target). At least some of them are unknown according to my knowledge, so even if they are known, it does not count, right? :)
Now the bitter part.
Over the entire year, I had an impression that MSRC leaderboard is missing points for the majority of my submissions. I was signalizing this issue a couple of times, but with no effect. I was even not on the initial MVR list.
After my small tweet, some of my missing points were found and I eventually made it to the list (thx MSRC for this intervention). The truth is – the list is not so important to me. I like to think about vuln disclosure as some mutually respected process.
I’m not collecting bounties (reporting as ZDI) and the only thing I want in return for my submissions is a proper acknowledgment. I think that this process failed in 2024, but I hope it will eventually get better. I have impression that I should have way more points, but whatever.
Another part – several of my submissions were rejected as an expected behavior. Not a nice feeling, but it’s a part of the game. I can see a lot of tweets about dropped submissions and this part concerns everybody. From my perspective, reporting of .NET vulns is hardest.
I have a small perception that if you cannot exploit something that you consider a .NET vuln in Exchange or SharePoint, it’s probably going to be ignored (based on my experience only). Well guess what, there are different products/apps based on .NET too :D
To sum up, quite a good year. Hoping to have an even better 2025, although my Exchange run from 2023/2024 will be hard to repeat.
I hope to deliver some nice research and to see you next year during conferences or wherever. Cheers

Parody site ClownStrike refused to bow to CrowdStrike’s bogus DMCA takedown
Parody site ClownStrike defended the "obvious" fair use.
After months of digging and reporting, I have learned where Facebook's bizarre AI spam (like "Shrimp Jesus") comes from, who is making it, how it works, and how it is monetized.
Turns out Meta is directly paying people to spam FB with this stuff

I have just added support in #Diaphora for #IDA 9.0 (currently in beta). I wrote the changes this weekend, but I had to test multiple things... anyway, enjoy it.
