Asprox: cg33.ru, cv2e.ru, cv32.ru, mc2n.ru, oc32.ru and vwsc.ru

Another bunch of Asprox SQL injection domains to block or monitor for, all quite new:

• cg33.ru
• cv2e.ru
• cv32.ru
• mc2n.ru
• oc32.ru
• vwsc.ru

Alternatively, look for .ru/script.js in your logs which should pick up most of them.

Update: here's another one - mj5f.ru

Atrivo / Intercage

Atrivo, Inc (also known as Intercage) and their main customer, Esthost (related to Estdomains) might well be a familiar name to people working in IT security. Atrivo is based is California and is run by one Emil Kacperski, so it has always surprised me that such a small operator should be a persistent host of malware.

Well, Atrivo's activities have not gone un-noticed by HostExploit.com who have produced a whitepaper and diagram and a YouTube video explaining how Atrivo's network is involved in a typical PC exploit.

Brian Krebs at the Washington Post has a comprehensive commentary. Note in particular the comments from "Emil K." at the bottom of the article. The RBN blog also has a comment here. Fascinating stuff.

Where a link turns into a lawsuit

I've seen some daft excesses in local politics in my time, but over Sheboygan, Wisconsin, things have taken a new twist... with a lawsuit over a link.

Jennifer Reisinger operates a website called Sheboygan Spirit which appears to be very critical of local officials and also a now defunct web design business called Brat City Web Design. She was also involved in a campaign to recall the elected mayor, which probably didn't endear her to some city officials.

Last year, the city filed a lawsuit against Ms Reisinger. Why? Because one of her sites carried a link to the Sheboygan Police Department (oops). First, the city sent a cease and desist asking her to remove it, and when she refused to do so they initiated a criminal investigation and legal proceedings.

Remember, this is just a link to the local police department. Not a link to illegal or confidential material. Of course, really the city didn't have a leg to stand on and in November 2007 decided not to pursue the case.

But Ms Reisinger wasn't finished, and a few days ago filed a counter-suit alleging loss of business and a violation of first amendment rights. It looks like it could be a significant case.. depending on the outcome.

There's more information in this item at the Milwaukee Journal Sentinel, and also here at the Citizen Media Law Project.

"Bank of America Installation and Upgrade Warning."

The bad guys are busy today, here's another fake bank "upgrade" leading to malware, following on from this one.

This leads to a very convoluted URL with an executable Setup_BankofAmericaclientno4508832.exe - virus detection for this one is a bit poor. Malware is identified variously as TR/ATRAPS.Gen (AntiVir & WebWasher), DeepScan:Generic.Malware.dld!!.083539B0 (BitDefender) and one or two others come up with a generic detection.

Incidentally, the URLs used in both attacks are incredibly long and convoluted.. and not terribly convicincing.

Avoid these "bank certificates" at all costs.

Tilde.exe in C:\Windows\System32 folder

This isn't really about tilde.exe at all, but a file called C:\Windows\System32\~.exe that has a habit of showing up on laptops that have been playing up with frequent browser crashes.

~.exe is kind of an odd name for a file, and crucially it's an ungoogleable name, because Google uses the tilde mark for its Synonym Search function.

Probing more deeply at the file shows that is is 34,616 bytes in size and is described internally as "Microsoft® Remote Std I/O Shell". The version information gives the following details:

• Company: Microsoft Corporation
• File Version: 6.0.6001.16470 (fbl_tools(patst).070215-1229)
• Internal name: remote.exe
• Language: Language Neutral
• Original File name: remote.exe
• Product Name: Microsoft® Windows® Operating System
• Product Version: 6.0.6001.16470

The icon is identical to the remote.exe sometimes supplied with various Microsoft debugging or support tools. Indeed, it does seem to be just another version of remote.exe which is a component of Microsoft's SMS server.

The ~.exe file may also be accompanied by a couple of strange-looking .dat files, for example __c0084F92.dat or __c00E460A.dat which on closer examination are actually executables.

It does genuinely seem to be a bit of Microsoft software, but in this case it would appear to be acting as a trojan downloader. The .dat files are lilely to be the second stage of the infection, and this could well be related to all the fake anti-virus products that have been promoted recently.

~.exe is detected variously as Trojan-Downloader.Win32.Agent.abnd, Win32/TrojanDownloader.Agent.ABND or Trojan:Win32/Vundo.gen!V (VirusTotal results here). The .dat file shows up variously as Trojan-Downloader:W32/FakeAlert.AN, TROJ_TIBS.CKN, Tibs.gen222, not-a-virus:AdWare.Win32.Agent.ekj (VirusTotal results here and here).

Removal: delete the ~.exe file and any unusual looking .dat files that match the above pattern. If the trojan is active, then one of the .dat files will be locked. The F-Secure Online Scanner seems to be able to safely remove this trojan, although a reboot will be required.

This is the first time that I have seen a Microsoft SMS component used in this way. Presumably it attempts to connect up to a back-end server that I have not yet been able to identify. It may well be that a corporate firewall would block such behaviour.

Asprox: beyry.ru, iopoe.ru, jetp6.ru, nucop.ru, port04.ru and vj64.ru

There's been a slight shift in the characteristics of the current Asprox attack. The javascript called is now script.js rather than ngg.js or js.js, and this goes to a redirect script currently pointing at /cgi-bin/index.cgi?lle on the local domain.

Active domains in this new attack seem to be as follows, new ones are in bold.

• beyry.ru
• cb3f.ru
• cnld.ru
• iopc4.ru
• iopoe.ru
• jetp6.ru
• loopk.ru
• netr2.ru
• okcd.ru
• nucop.ru
• port04.ru
• ueur3.ru
• vj64.ru

Check your logs or block these domains. Most business outside of Russia and neighbouring countries could probably block the entire .ru TLD with minimal impact. Look also for the CGI sript (/cgi-bin/index.cgi?lle) to find potentially infected client PCs.

Asprox: iopc4.ru, jetp6.ru, loopk.ru, netr2.ru and ueur3.ru

The domains used is the Asprox SQL injection attack have been stable for most of the past week, but over the last 24 hours some ne wdomains have been registed, so check your logs and/or block the following:

• iopc4.ru
• jetp6.ru
• loopk.ru
• netr2.ru
• ueur3.ru

It is likely that some more will turn up during the course of the day.

Another SQL injection domain: mo98g.cn

I mentioned some days ago that there seems to be a parallel SQL injection attack to Asprox with all the hallmarks of being Chinese. Over the past day or so, mo98g.cn has appeared on some infected sites (often alongside Asprox) making a call to mo98g.cn/q.js which is hosted on 222.122.128.5 in South Korea.

The back end seems not to be working at present, so maybe the server has been cleaned up. In any case, this is another domain to block or check your logs for.

Asprox: ujnc.ru

Just a single new Asprox domain to list this morning: ujnc.ru which is still using the js.js redirector, i.e. www.ujnc.ru/js.js. All the domains from the past two days are still active too.

Asprox: 3njx.ru, cb3f.ru, cnld.ru, nbh3.ru and okcd.ru

Some more Asprox domains to block or look for in your logs:

• 3njx.ru
• cb3f.ru
• cnld.ru
• nbh3.ru
• okcd.ru

Renewed Asprox activity: bcus2.ru, jkn3.ru, juc8.ru and locm.ru

After a quiet few days, Asprox seems to have flared up again (at about 1000 CET) with a new set of malware domains, still launching from a SQL injected js.js file on compromised hosts. Keep an eye out for these domains or block them.

These domains are all very recently registered through naunet.ru, there are probably many more on the way soon.

• bcus2.ru
• jkn3.ru
• juc8.ru
• locm.ru

All quiet on the Asprox front?

For the moment the Asprox SQL injection attacks seem to have stopped, although infected sites are still infected and need to be secured as soon as possible.

So, does this mean that the bad guys have given up? Well, no.. but there are probably thousands of sites out there which are still infected, so from that point of view they will still be getting "hits" to their malware sites.

Perhaps the answer is this - the people behind the SQL injection attacks are doing something else. Two very newsworthy events happening over the past few days have been the war in Georgia and the Beijing Olympics. Dancho Danchev reports that the RBN have been actively involved in attacking Georgian sites, including using SQL injection attacks. F-Secure report that Chinese sites have been attacked since the run-up to the Olympics started.

It might well be that these Asprox attacks will be quiet for a couple of weeks, but it is likely that general SQL injection attacks will ramp up again soon.

Spammers are still stupid

Another case where a spammer is too stupid to use the spamming tool they have just bought.

Option 1 - You can put ANY text you want in here.

Option 2 - We will fill it in with the text only portion of the
html message if you put the macro for you: [url removed]

NOTE: Some email clients don't disply html data. In that case what you

display html data then this will NOT be seen by the recipient.
Based on this you may wish to put a text version of your add here;
however, you can also put some macros here to make the message

Or use Option 3 and don't add anything at all. Idiot.

In this case the target file to download is msgr8.5us.exe, VirusTotal detection is pretty good.

Expect to see a LOT of these over the next few days, either themed for the Olympics or the war in South Ossetia. Although the subject will always change, a crash course in user education can help to mitigate the risk.

ISC: "More SQL Injections - very active right now"

The Internet Storm Center has published technical details on the Chinese-based SQL injection attack which may be of interest to SQL administrators and programmers and also security specialists. It also flags up another javascript file to look for: csrss/w.js

Keep an eye out for log activity pointing to this file. Blocking the entire .cn TLD will probably do very little harm for most businesses.

Asprox: block 91.203.93.4 and js.js

A shift in behaviour from the Asprox botnet - this time all traffic from infected sites is being redirected through a fixed IP at 91.203.93.4. Blocking 91.203.93.0/24 will probably do no harm.

Also, the name of the javascript file has changed to js.js, so look for this in your logs.

The Silent Noise blog is tracking Asprox domains too, with some interesting developments that we haven't had the chance to dig deeper into.

Asprox domains: 5/8/08

Current Asprox domains to look for in your blogs or block. These have all been active for 3 or 4 days now, which is an unusually long time for this current SQL injection attack.

• 8hcs.ru
• 98hs.ru
• bgsr.ru
• bywd.ru
• ibse.ru
• ncbw.ru
• nwj4.ru
• ojns.ru
• porv.ru
• uhwc.ru

Asprox domains: 2/8/07

These are the currently active Asprox domains to check for. They are all very recently registrations.

• 8hcs.ru
• 98hs.ru
• bgsr.ru
• bywd.ru
• ibse.ru
• ncbw.ru
• nwj4.ru
• ojns.ru
• porv.ru
• uhwc.ru

Fake "Correspondence manager" job

Money mule scams are now very common - basically some poor fool ends up laundering money or reshipping goods following the instructions of someone they have never met and is likely to be untraceable.

This particular job offer seems to go a step further. This "correspondence manager" could well be another layer in the scammer's obfuscation. Perhaps the correspondence manager handles communications with the money mules?

One danger here is that this particular role is more credible that the "money for nothing" jobs that scammers usually offer. On the face of it, it doesn't involve handling money, but it does seem to be very easy and the salary looks attractive.

There's an interesting bit of social engineering where the email says "THE SELECTED CANDIDATE MUST PASS A CRIMINAL BACKGROUND CHECK". Of course, it is the employer who needs to pass a background check too. Always verify that your job offers are from a genuine, verifiable business.
