There have been several reports about malware hosted on Mozilla and Google code servers. Now we also found malware hosted on My Opera community servers. The screenshot below shows an example of this:

It’s a PHP based IRC botnet. Analyzing the code I found some evidences that it comes from Brazil.

We can see that criminals appreciate and actively use any and all available free web space. Based on the statistics from one of our proactive web crawlers, I took a look at which free web hosts are most popular among criminals for uploading and spreading malware. The following graph shows the top 10 free web hosts used by criminals during the last 8 months:

Fileave is a really well known server for hosting tons of different kinds of malware. I noticed that some secure DNS providers block access to the domains listed above and show an alert message stating that these sites are known sources of phishing and malware. So, what does that tell us? The usual - when you browse the internet always check links before clicking, and if the domain is suspicious, don't. Just don't click. And if you’re owner of a web site, make sure to secure your server properly to prevent the criminals from compromising it easily.

    Some months ago I wrote a blog post called “Rogue AV raising the stakes” which mentioned a new trend in the graphical user interfaces of Fake Anti-viruses. Our predictions were correct, as today my colleague Fabio Assolini found a Web site with an interface very similar to Kaspersky Anti-Virus. See for yourself:

This isn’t the first time we’ve found this kind of fake imitation of our solutions. The interesting part is that during our research we found fake versions of other Anti-Virus solutions on the same malicious host. Can you spot the difference?

These are just some of the examples. Since some Internet users know what the most popular Anti-Virus solutions look like they can be confused and pay for a Rogue AV solution. This is the main goal of the criminals; to confuse as many people they can, and to get as much money as possible.

On this same malicious server we found 256 different malicious rogue domains with different content but with the same intention: to cheat people by making them pay money for nothing.
Please be careful and always check the domain of the page you're visiting. Don't be a victim of criminals!

1. Greediest Trojan targeting banks
   This month, the nomination goes to Trojan-Banker.Win32.Banker.xkz, from the same family that won this category last month. This particular sample targets the users of 28 banks at once.
   
2. Greediest Trojan targeting payment systems
   September's winner is Trojan.Win32.Agent.adtp which has its sights set on four e-payment systems simultaneously.
   
3. Greediest Trojan targeting payment cards
   It's been a long time since we've seen a malicious program which wins out in more than one category.

4. Stealthiest malicious program
   Autumn has brought about a change in this category - instead of the customary Hupigon, September features a modification of Backdoor.Win32.Netbus.160.e, which is packed with nine different packers.
   
5. Smallest malicious program
   September's winner, just like August's, is 31 bytes in size, but has a different payload - it's a new modification of Trojan.BAT.MouseDisable.c. And its name tells you everything you need to know - this Trojan will block the mouse.

8. Most common malicious program on the Internet
   Trojan-Downloader.Win32.Small.aacq, which won this category last month as well, still triumphs here; it's involved in 20% of all cases, which is a pretty high number!
   
9. Most common Trojan family
   Once again, this category is taken by an old familiar: Backdoor.Win32.Hupigon.c, which came over the finish line in September with 3072 new modifications.
   
10. Most common virus/ worm family

1. Greediest Trojan targeting banks
   Trojan-Banker.Win32.Banker.rqk leads this month, even though it only attacks 26 banks, a relatively low number.
   
2. Greediest Trojan targeting payment systems
   In August, a new modification of Backdoor.Win32.Agobot.gen won this category by targeting four payment systems simultaneously.

   Trojan-Banker.Win32.Banker.qhq targets three payment systems simulaneously
   
3. Greediest Trojan targeting payment cards

7. Most common vulnerability on the Internet
   The category 'Most malicious program', a fixture in previous Miscellanies, is no longer particularly indicative of the malware landscape. So this month we've introduct a new category – 'Most cmmon vulnerability on the Internet', i.e. the one most exploited by malicious users. This month the victory goes to Trojan.Clicker.HTML.Iframe.sy, which makes up more than 12% of all vulnerabilites found on web pages used by malicious users to infect victim machines.
   
8. Most common malicious program on the Internet
   The category 'Most common malicious program in email traffic' has also changed. Readers of this column may remember that the winner of that nomination remained unchanged over several months. In order to give a more representative picture, this cateogory is now called 'Most common malicious program on the Internet. Trojan.Win32.Agent.sav wins out in July, as it was involved in 5.52% of all attempts to infect users.
   
9. Most common Trojan family

   Here, naturally enough, there's another password stealing Trojan: Trojan PSW.Win32.Agent.apl has its sights sent on four payment card systems
   
4. Stealthiest malicious program
   Trojan-PSW.Win32.Delf.jj wins this month, as it's packed with eight different packers.
   
5. Smallest malicious program
   Trojan.BAT.KillFiles.hx is rather larger than last month's winner in this category but is still only 26 bytes in size. It's capable of wiping the contents of C:.
   
6. Largest malicious program
   June's winner, Trojan Banker.Win32.Bancos.mk, at 31MB in size, is by no means the largest program we've seen in this category.
   
7. Most malicious program
   Once again Agobot makes an appearance, with a modification of Backdoor.Win32.Agobot.gen victorious this month. Its payload holds no surprises: it deletes a wide range of security products both from memory and from disk.
   
8. Most common malicious program in email traffic
   This category doesn't seem to change much from month to month: our old friend, Email-Worm.Win32.Netsky.q again takes the prize, having made up 34.15% of infected mail traffic in June.
   
9. Most common Trojan family
   3295 different modifications of Trojan-GameThief.Win32.OnlineGames were detected this month.
   
10. Most common virus/ worm family

1. Greediest Trojan targeting banks
   Trojan-Spy.Win32.Banker.mrj comes out as the greediest banking Trojan in May, targeting the clients of 103 banks simulataneously.
   
2. Greediest Trojan targeting payment systems
   Although Trojan-PSW.Win32.Staem only targets a relatively modest three payment systems, it still comes out top in this category.
   
3. Greediest malicious program targeting payment cards
   This month, one of the new modifications of Trojan-Spy.Win32.Banker.tq takes the prize, targeting five payment card systems at once – no mean feat for malware in this category!
   
4. Stealthiest malicious program
   May's stealthiest piece of malware is from an old family: the winning modification of Backdoor.Win32.Hupigon.bxbu is packed nine times over.
   
5. Smallest malicious program
   Trojan.Bat.KillWin.dg, in spite of being a minimal 15 bytes in size, is still able to destroy Windows on the user's disk.
   
6. Largest malicious program
   Although this month's winner, Trojan-Spy.Win32.Banker.fgw is a chunky 30MB in size, that's by no means a record for this category.
   
7. Most malicious program
   A modification of Backdoor.Win32.Agobot.pgj wins the prize for maliciousness in May, as it combats antivirus solutions by deleting security software from victim machine.
   
8. Most common malicious program in email traffic
   For the nth time, we've got Email-Worm.Win32.Netsky.q leading this cateogory, as it made up 23.12% of all malicious mail traffic in May.

   There's another old-timer here: 3301 new variants of the Backdoor.Win32.Hupigon family appeared in May.
   
10. Most common virus/ worm family
    This category shows more variation than the preceding two: Net-Worm.Win32.Kolab.c, in 276 modifications, is a new winner of this nomination.
