Malware hunt – wildfowl to find

2014.01.31

More than twice for the last 24 hours I was asked the non-trivial question:

Where do You find the targets for the malware hunt, if You’re not a  part of the big team, malware researcher or not own a honeynet.

Actually, if You do want to fight a malware, IMHO it is very useful to have a honey-pot system, or, at least, be in security business somehow. It will provide You a non-stop flow of the malicious targets to review. But if  You not, and You still want to help?

JavaScript PluginDetect is in the Past.

2013.07.14

Well, I am sick again, alone at home, so looking for something to dig in…

And, as it appear to be, there is always something interesting happened.

If You familiar with ExploitKits, You know, that major feature of traffic filter is – PluginDetect.

It is JS script with huge amount of features, provided by legit and respectful authors.

Main usage for malicious purposes – detect an outdated plug-ins to serve “working” exploits for successful infection of a victim.

Size  – about 45-65 Kb in plain text, in altered\obfuscated mode can reach 110-130 Kb of JavaScript.

It also known to be part of malicious applications,  and triggered respectively. There are products, that emulate JS, provide fake responses to PluginDetect to bypass it successfully.

Well, bottom line – it’s quite a mess to use it for traffic filtering.

But there are other ways, always…

2013.03.18

DarkLeech – malware mod for Apache.

2012.09.16

It was expected, actually…

But – from the beginning.

Few last weeks I read about some strange malicious activity on Apache servers (WebmasterworldUnmaskParasites.com):

Iframe with malicious code was injected in multiple pages of Apache server dynamically.

Standard cleanup was not helpful at all, multiple co-located hosts were infected the same way.

Any website, moved to new server, became clean << When I saw this, it became obvious, that compromise is part of web-server itself, not per site.

So – I made a little research, and found  new product on black market, that You may be interested in 🙂
