W32/IRCBot-AEH
by Marianna Schmudlach / May 12, 2009 12:00 AM PDT

Category

* Viruses and Spyware

Type

* Worm


W32/IRCBot-AEH is a worm with IRC backdoor functionality for the Windows platform.

W32/IRCBot-AEH runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

When first run W32/IRCBot-AEH copies itself to <System>\wmisynd.exe and creates the file <System>\drivers\sysdrv32.sys.

The file wmisynd.exe is registered as a new system driver service named "WMISYND", with a display name of "WMI Sync-DB" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:

HKLM\SYSTEM\CurrentControlSet\Services\WMISYND

Tored-A email worm for Mac OS X called "lame"
by Marianna Schmudlach / May 12, 2009 12:29 AM PDT

May 12th, 2009

Posted by Jason D. O'Grady

Last week fellow ZDNet blogger Dancho Danchev posted a piece about a new email worm that has been discovered for Mac OS X called OSX/Tored-A.

Most of the examples of Mac malware that have surfaced recently (like OSX.Trojan.iServices.A and OSX/RSPlug-F) are actually Trojan horses that are distrubed via P2P networks packaged with commercial software.

Sophos notes that Tored-A is different than the other recent Mac malware that been discovered:

Pushdo/Cutwail ? The Art of Spamming
by Marianna Schmudlach / May 12, 2009 12:39 AM PDT

May12

Unless you?ve been off the Internet for the last seven years, you?ve probably heard of the massive security problem: botnets. These networks of infected computers commanded by criminal outfits can launch coordinated attacks, host malicious websites or send spam - lots of it.

One of the biggest spamming botnets out there is Pushdo, a botnet that despite being responsible for 7.7 billion spammed emails per day worldwide, has managed to stay under the radar since 2007. It has even managed to make it consistently to the Top 5 largest botnets without ever reaching number one, and is the Top 2 largest spamming botnets worldwide. Poor Pushdo, always the bridesmaid, never the bride!

In reality the Pushdo botnet is a very fancy software distribution platform. Once the victim is infected, Pushdo phones home asking for a bunch of malware executables, a lot of which are third party malware. This is the only kind of communication with the command & control server; no P2P components, just very frequent updates from the central server, one typically hosted in the US. Pushdo seems to have missing out compared to Storm and Downad, but its complete lack of self-propagation and simple C&C structure does not seem to have hampered it in the least.

Fake Antivirus Targets Brazil
by Marianna Schmudlach / May 12, 2009 12:40 AM PDT

Fake/rogue antivirus strikes again, this time targeting the users in Brazil. Like in today?s malware trends, it did not come alone.

It initially starts with a spam message:

SUBJECT:
Hello, I am sending you my invitation to the graduation location, date and time

BODY:
Hello, I am sending you my invitation to the graduation location, date and time.
I count on your presence.
We are there,

Yet More Swine Flu Attacks
by Marianna Schmudlach / May 12, 2009 12:41 AM PDT

Spammers know a thing or two about persistence, it seems. CNET reports a new Trojan?TROJ_QHOST.TB?that is the latest to take advantage of fears of swine flu. TROJ_QHOST.TB modifies the HOSTS file of any affected system, which results to the user being redirected to a spoofed banking-related website whenever they attempt to access the real ones. By which, users are placed at risk of getting their banking information stolen and having it used by an unauthorized user.

The attack is pretty similar to earlier ones that have also taken advantage of the swine flu. Spam messages with warnings contain either a link to a malicious website or an attachment to TROJ_QHOST.TB. In turn, the Trojan modifies the system?s HOSTS file to redirect users of certain Mexican banks to a specific IP address.

Fortunately, however, the said IP address doesn?t work anymore. However, there?s nothing that stops future variants?or other Trojans?from using the same lure. Users should consider themselves warned.

Cybercriminals Launch Tainted Windows 7 RC
by Marianna Schmudlach / May 12, 2009 12:42 AM PDT

The official launch of the Windows 7 Release Candidate last May 5 was soon followed by another version of the software, only that this other version came with a malware surprise.

A file being hosted in popular torrent sites posing as a copy of the Windows 7 RC was found to be a Trojan by security researchers. The file which arrives with the file name setup.exe is detected as TROJ_DROPPER.SPX. TROJ_DROPPER.SPX drops TROJ_AGENT.NICE. Both files are detected by the Smart Protection Network.

Windows 7 Release Candidate was leaked a couple of weeks prior to the official release, and was also hosted by and downloaded from popular torrent sites. This was followed by a reported downtime in the download page for the Windows 7 Beta, which was attributed to too many download requests.

With Windows 7 showing much promise as early as now, it isn?t really surprising that cybercriminals are using the operating system to distribute malware not necessarily as a platform, but as a social engineering technique.

Those interested in obtaining a copy of the release candidate are advised to get it from the Microsoft Windows 7 website.

Meet the drop-resistant Moto Z2 Force

The Moto Z2 Force is really thin, with a fast processor and great battery life. It can survive drops without shattering.
