Active #RDP connections can reveal the client hostname 🔎 A key indicator for investigations & #CTI: some attackers reuse hostnames. Traces to check: CLIENTNAME env variable & RDP printer redirection. 🛡️ Incident? Contact #Synacktiv CSIRT 24/7: [email protected]

I recently gave my 1st talk at an infosec conf (hack.lu 2025) w/ @Aeinot_ From our joint perspective (a Red Teamer and a DFIR analyst), we provided insights on how to use Blue Team tools to the Red Teamer's advantage. youtube.com/watch?v=XDFWsWIA…

Recent attacker tradecraft, documented by Huntress (huntress.com/blog/velocirapt…), Talos Intelligence (blog.talosintelligence.com/v…) and Sophos (news.sophos.com/en-us/2025/0…) proves that we weren't that far off. 🤓

If you're interested in YARA and Sigma rules linked to this research, check them out on our dedicated repository: github.com/synacktiv/synackt…
In recent incident responses with an Ivanti CSA compromise as the root cause, Synacktiv's CSIRT came across open-source tools used for post-exploitation. Our ninja @Cybiosity explores their functionalities and discusses detection capabilities. synacktiv.com/en/publication…

If you're interested in detecting exploit scripts associated with these vulnerabilities, Sigma correlation rules are available right here: github.com/synacktiv/synackt… Feel free to test them out, any feedback is appreciated 🙏
In 2024, Fortinet deployed several patches for CVE-2023-42791 and CVE-2024-23666, discovered by @Aeinot_, Paul Barbé and @loadlow. These vulnerabilities allow, from read-only access to a FortiManager, to execute code as root and thus take control of all managed FortiGates. synacktiv.com/advisories/for…

Hello everyone! Our team loves everything related to LPE exploits. However, there is no publicly available list on the web with fresh LPE exploits (2023-2024) for Windows. However, we do have such a list. And we are sharing it with you! github.com/MzHmO/Exploit-Str…

A few months ago, the @freebsdfndation appointed us to audit two #FreeBSD critical components: the Bhyve hypervisor and the Capsicum sandboxing framework. Today, related advisories and patches have come out 🧵 1. Multiple vulnerabilities in libnv freebsd.org/security/advisor…

It's been really fun trying to fit my weird use case into @velocidex ! There is still work to accomplish, but I like to think it could be useful in remote #Veeam #DFIR investigations.
Want to collect forensic data from remote Veeam backups? @Cybiosity's exploration of remote Veeam forensics with Velociraptor might be what you're looking for! synacktiv.com/publications/u…
