Attackers are everywhere! They try to abuse victims using new communication channels and social engineering techniques! Somebody pointed my to the following Tik-Tok video: hxxps://vm[.]tiktok[.]com/ZGdaCkbEF/.

This week, we set up a new Slack workspace for DShield.org. This workspace replaces the old workspace we originally configured back in 2016 or 2017. The workspace was originally configured as a free workspace to support the DShield.org community. Over the years, it has had a good following and a good amount of traffic.

For a while, clipboard content has been monitored by many infostealers. Purposes can be multiple, like simply searching and exfiltrating juicy data or on-the-fly modification like crypto-wallet swapping[1]. Note that the clipboard is a major risk when you don't disable clipboard sharing between your virtual machines and hosts. A malware running in a sandbox will access your (host) clipboard without problem!

I am experimenting today with a little bit of a cleaned-up patch overview. I removed vulnerabilities that affect Microsoft's cloud systems (but appreciate Microsoft listing them at all), as well as vulnerabilities in third-party software like open source libraries. This should leave us with Microsoft-specific on-premises vulnerabilities. This month, this leaves 157 different vulnerabilities. Eight of the vulnerabilities are rated critical.

In January, a possible XSS vulnerability was found in the electronic document security management system ESAFENET CDG. This was the latest (as far as I can tell) in a long list of vulnerabilities in the product. Prior vulnerabilities included SQL injection issues and weaknesses in the encryption used to safeguard documents. In other words: A typical "secure" document management system. The product appears to be targeting the Chinese market, and with a website all in Chinese, I doubt it is used much, if at all, outside China.

Wireshark release 4.4.10 fixes 6 bugs and 1 vulnerability (in the MONGO dissector).

Today, I spoted on VirusTotal an interesting Python RAT. They are tons of them but this one attracted my attention based on some function names present in the code: self_modifying_wrapper(), decrypt_and_execute() and polymorph_code(). A polymorphic malware is a type of malware that has been developed to repeatedly mutate its appearance or signature files at every execution time. The file got a very low score of 2/64 on VT! (SHA256:7173e20e7ec217f6a1591f1fc9be6d0a4496d78615cc5ccdf7b9a3a37e3ecc3c).

FreePBX is a popular PBX system built around the open source VoIP system Asterisk. To manage Asterisk more easily, it provides a capable web-based admin interface. Sadly, like so many web applications, it has had its share of vulnerabilities in the past. Most recently, a SQL injection vulnerability was found that allows attackers to modify the database.

[Update: I added the server part delivering the payload]
