For the 10 of you who don’t know, darkode was on of the most active English-speaking “underground” cybercrime boards. The forum was started around 2009 by a coder named “Iserdo” and gained popularity off the back of Iserdo’s bot, “Buterfly bot” (AKA Mariposa), which was sold there. In The Beginning …

I’ve been withholding this article for a while, due to the fact that the minute I post it all the vulnerabilities will be patched, thus becoming useless to us; however, it turns out hacking all of the phase C&C panels has generated a bit of noise, resulting in the vulnerabilities …

OphionLocker is supposedly the new ransomware on the block and is already being compared with sophisticated operations such as CryptoLocker and CryptoWall, so i decided to take a look and what I found is nothing short of hilarious. That’s right, the ransomware is actually a console application, Instead of writing …

As I said in the last part of the analysis the sample I had was just a test binary, but now I have some real ones thanks to some help from @Xylit0l. The new binaries incorporate some much more interesting features which I’ll go over in this article. Reverse Connection …

Phase Bot is a fileless rootkit that went on sale during late October, the bot is fairly cheap ($200) and boasts features such as formgrabbing, ftp stealing, and of course the ability to run without a file. The bot has both a 32-bit binary (Win32/Phase) and a 64-bit binary (Win64/Phase), …

A long long time ago (about 10 years in non-internet time) malware developers only had to worry about signature based detection, which could be easily bypasses with polymorphic droppers or executable encryption. To deal with rapidly evolving malware, capable of evading signature detection, HIPS was created. HIPS (Host-based Intrusion Prevention System), sometimes …

A virtual File System (VFS), sometimes referred to as a Hidden File System, is a storage technique most commonly used by kernel mode malware, usually to store components outside of the existing filesystem. By using a virtual filesystem, malware developers can both bypass antivirus scanners as well as complicating work …

A few days ago I published an article detailing how a second bug, in the schannel TLS handshake handling, could allow an attacker to trigger the DecodeSigAndReverse heap overflow in an application that doesn’t support client certificates. I had stated I was not familiar with ECC signatures and was unsure …

If you’ve been in a coma for the past week, MS14-066 (CVE-2014-6321) is a TLS heap overflow vulnerability in Microsoft’s schannel.dll, which can result in denial of service and even remote code execution on windows systems (the bug is exploitable during the TLS handshake stage, prior to any authentication). According to beyondtrust the …

I had a cool idea for a way to get the user to passively elevate your application without socially engineering them to do so or requiring exploits. Obviously you could just go ahead and start mass infecting executables, but that would cause a lot of unforeseen problems and would also …
