Hi folks, as a_d_13 recently announced, he transferred the domain and forum over to me as the new admin. I want to thank him for his effort and time he put into it over the course of the last 8 years! He will still be available on the forum as a global moderator if you want to contact him. For those...

Hi folks, Symantec published an article about a group they named Longhorn whose tools match the descriptions of the Vault 7 documents leaked by Wikileaks, allegedly the CIA hacking tools arsenal. In the article, they also published the signature names of some tools of which some can be found on Viru...

Hi folks, here are two samples of Backdoor.Batel, a small shellcode like dll file. Nothing special though, the technique is nearly identical to the one described here, except this time it's realized as a standalone dll: https://blog.cylance.com/operation-cleaver-the-notepad-files PDB path string: C:...

ATM (Diebold) related file

Hi folks, maybe someone can shed some light into the functionality of this small ATM related file. It doesn't look malicious to me, but I can't say for sure since the Diebold API isn't public. Perhaps it's useful for someone... File: https://virustotal.com/en/file/d2296deb1b6ae42d787889e163d8d75a43c...

Hi folks, here are two fresh samples from beginning of September which aren't crypted. They look like some test samples, because they have "-testldr" command line switch among other things. Samples also contain two small embedded dlls (x86/64) which seem to deal with certificate related stuff. Haven...

Here are a few new versions. The droppers are mostly self-extracting RAR archives which contain a legit version of Teamviewer (v7) and a parasitic file named msimg32.dll. It seems to have kind of new UAC bypass method on board, but haven't checked in detail. Strings of msimg32.dll: F123456789ABCDEFG...

Here is the exploit known as CVE-2015-2360. It wasn't publicly released yet, so I thought to upload it before it gets lost in my archive. The compilation time stamp is a bit newer than the samples described by Kaspersky, though I don't think there is a big difference in the functionality, if at all....
