The TDSS botnet, now in its 4th generation, is seriously sophisticated malware, which is why we've spent so much time writing about it: the revision of the paper The Evolution of TDL: Conquering x64 that will be up on the white papers page shortly runs to 54 pages and includes some highly technical analysis, including the detail on

Recently … our TDL tracker picked up a brand new plugin for TDL4 kad.dll (Win32/Olmarik.AVA) which we haven’t seen earlier … we discovered that it implements a particularly interesting network communication protocol …

The US Department of Justice's announcement yesterday of the takedown of the command and  control (C&C) servers for the Coreflood bots (detected by ESET as Win32/AFCore) and seizure of their domains marks another step in the growing awareness that crime, whether it is committed with bullets or with botnets, is still crime.  This particular botnet,

Here’s a little information from ESET’s point of view about the Coreflood botnet, whose C&C (Command and Control) servers were taken down yesterday by the Department of Justice. The Coreflood bot is detected by ESET products as Win32/Afcore and has been active since the early years of the last decade (certainly since 2001), though our

I don't want to flog (or blog) this iPhone bot thing to death: after all, the number of potential victims should be shrinking all the time. However, having updated my previous blog (http://www.eset.com/threat-center/blog/2009/11/22/ibot-mark-2-go-straight-to-jail-do-not-pass-go)  on the topic a couple of times, I thought I'd actually go to a new blog rather than insert update 3. So here are the update bits

We’ve just finished working on our monthly Threat Report. There aren’t many surprises in the top ten threats for June. Conficker has taken over the "top spot", relegating INF/Autorun to second place. It’s difficult to say for sure what the significance is, given the relatively small percentage point involved: minor fluctuations in proportions from month

Some more information on the Hexzone botnet has come my way, mostly from FireEye’s Atif Mushtaq and Paul Ferguson’s hairdresser (don’t ask!). Atif also mentions the association with ransomware: the malware is installed as a Browser Helper Object (BHO) on the victim’s machine, and hijacks browsing sessions, taking the victim to a page hosting pornography.

I don’t, of course, know for sure what’s going to happen on April 1st, when Conficker is timed, potentially, to go to its next stage of evolution. We do know, from inspecting code in the variants and subvariants that have come our way, that infected machines will be looking for instructions and updates on that date. At the very least,

The estimable Graham Cluley’ drew my attention in his blog to the fact that this is National Zombie Awareness Week in Australia. A zombie is security geekspeak for a PC that has been infected by a bot or agent, so that it’s added to a network of compromised machines (a botnet) under the control of

A few days ago, I promised (threatened) to make some general points about biasing test results, but travel and other obligations have been getting in the way. I’ll get back to that very shortly, but in the meantime, I want to look at an issue with the latest round of Microsoft patches that I was
