Macvirus.org site compromised

March 10, 2008 - "...Macvirus.org, a website dedicated to “keeping an eye on Mac viruses”, has had their discussion forums seeded with vast amounts of forum spam pushing various junk and lots of hardcore porn, including a number pushing malware (fake codecs)... pushing fake codecs for -both- Mac and Windows platforms (the site serving the fake codec simply detects your user agent and delivers the appropriate malware)..."

Annual Weblog Awards ("Bloggies") site compromised
- http://blog.trendmicro.com/bloggies-gives-out-malware-before-awards/
March 10, 2008 - "...The Web site of the Annual Weblogs Awards — more informally known as the Bloggies — was hacked recently, serving up a malicious Javascript to its visitors. This happened on the eve of the award ceremony, as reported in NEWS.com.au*. Upon loading, the site reportedly connects to the URL hxxp ://www.{BLOCKED}nwww.biz/1/1/ice-pack/ index.php that Trend Micro researchers have verified to be malicious. It downloads the file INDEX.PHP, which is detected as JS_PSYME.ANT. This JavaScript Quicktime exploit in turn connects to the URL hxxp ://{BLOCKED}nwww.biz/1/1/ice-pack/ exe.php to download a file that is detected as TROJ_DROPPER.XX. Whoever orchestrated this attack played on timing, knowing that people would more likely visit the Bloggies Web site on the eve of the awarding ceremony itself. Unfortunately, safe surfing measures can be useless as even the most trusted Web sites can be hacked to serve up malware... Trend Micro advises surfers to keep their software updated, especially their AV products to evade infection."

Hundreds of Web sites infected - attack in progress

FYI...

- http://www.avertlabs.com/research/blog/index.php/2008/03/12/another-mass-attack-underway/
March 12, 2008 - "On the heels of recent iframe attacks, we’re currently tracking another mass compromise. This attack involves injection of script into valid web page to include a reference to a malicious .JS file (sometimes in the BODY, other times in the TITLE section). The .JS file uses script to write an IFRAME, which loads an HTML file that attempts to exploit several vulnerabilities, including:
* MS06-014
* RealPlayer (ActiveX Control)
* Baofeng Storm (ActiveX Control)
* Xunlei Thunder DapPlayer (ActiveX Control)
* Ourgame GLWorld GlobalLink Chat (ActiveX Control)
This is one of those cascading threats, where one page leads to another and another, which leads to an executable, which leads to another and another. At least one of the payload trojans targets online gamers. Preliminary research results suggest more than 10,000 pages were affected by this hack attack..."

March 13, 2008 (Computerworld) - "...The Web attack, which appears to be a coordinated effort run out of servers in China, was first noticed by McAfee researchers on Wednesday morning. Within hours, the security company had tracked more than 10,000 Web pages infected on hundreds of Web sites... This same technique was used a year ago, when attackers infected the Web sites of the Miami Dolphins and Dolphins Stadium just prior to the 2007 Super Bowl XLI football game. The attack code takes advantage of bugs that have already been patched, so users whose software is up-to-date are not at risk. However, McAfee warns that some of the exploits are for obscure programs such as ActiveX controls for online games, which users may not think to patch. If the code is successful, it then installs a password-stealing program on the victim's computer that looks for passwords for a number of online games..."

13 March 2008 - "...Compromised web pages include travel sites, government websites, and hobbyist sites that have been modified with JavaScript code that silently redirects visitors to a site in China under the control of hackers. Miscreants likely reprogrammed the web pages after scanning the net for insecure servers. The malware cocktail attempts to exploit vulnerabilities in Windows, RealPlayer, and other applications to break into insecure PCs... Components of the malware attempt to steal passwords to online games while others leave a back door that allows the installation of additional malicious programs... A single organisation or small group is likely behind this attack, as the malicious code on all these pages is served up from the same server in China..."

Trend Micro site infected users with Trojan

FYI...

- http://preview.tinyurl.com/39s9kz
March 13, 2008 (Computerworld) - "Antivirus vendor Trend Micro Inc. confirmed Thursday that "some portions" of its site had been hacked earlier this week, but hedged when asked if those pages had been serving up attack code to unsuspecting visitors... The English-language edition of the Yomiuri Shimbun, one of Japan's largest newspapers, said Trend Micro's site was hacked around 9:00 p.m. Sunday, Tokyo time (7:00 p.m. Eastern, on Saturday, in the U.S.)... The alert also said that users could have been infected by accessing one of 11 infected pages on the Japanese site or 20 pages on the English site, or by clicking a link embedded in the malware's name. All the pages were part of Trend Micro's malware encyclopedia, a searchable database of viruses, Trojans and worms. Sweeny, Trend's U.S. spokesman said "about 32" pages were involved, "most of them from the encyclopedia." Other reports speculated that the Trend Micro hack was part of the larger campaign that has infected some 20,000 pages in the past few days. According to researchers at McAfee Inc., those hacks are script-injection attacks that reference JavaScript attack code..."

"...According to reports in the Japanese media, a number of webpages on the firm’s Japanese and English-language website were altered by hackers on Sunday 9 March, who used a malicious iFrame exploit to deliver a Trojan horse onto surfers’ computers. Trend Micro is believed to have uncovered the problem on Wednesday 12 March and replaced affected pages with a message saying “This page is temporarily shut down for emergency maintenance”... It is believed that a SQL vulnerability on the site was exploited by the hackers... In a nutshell - what has happened here is a criminal act, and our friends at Trend Micro (and people visiting the hacked pages) are victims of the crime... This isn’t the time or place to make cheap shots against a competitor... Sophos discovers a new infected webpage every 14 seconds..."

March 13, 2008 (AvertLabs blog) - "Yesterday we uncovered a newer mass hack affecting over 10,000 web pages. That number has since doubled. Today, I took a look at another recent mass attack, which was similar to those reported by Dancho Danchev, but reference a JS file rather than an IFRAME. The attack seems to have started more than a week ago, and nearly 200,000 web pages have been found to be compromised, most of which are running phpBB. This contrasts yesterday’s attack in that the vast majority of those were active server pages (.ASP). The ASP attacks are different than the phpBB ones in that the payload and method are quite different. Various exploits are used in the ASP attacks, where the phpBB ones rely on social engineering. phpBB mass hacks have occurred in the past, including those done by the Perl/Santy.worm back in 2004..."

"Situation:
Over 10,000 legitimate websites [should read "pages"?] have been compromised and now have an iframe that will direct visitors to a malicious website hosted on 2117966.net. The malicious website attempts to exploit the vulnerability described in MS06-014 MS07-004, MS06-067, MS06-057 and a number of ActiveX vulnerabilities. Successful exploitation result in the installation of a password-stealing malicious program that attempts to steal the logon credentials from websites and online games.
- Recommended immediate action:
Block 2117966.net at your web proxy
- Recommended follow-up action:
Inspect your web proxy logs for visitors to 2117966.net. This will indicate who is potentially exposed. Check these systems to verify that their patches are up-to-date. Systems that are successfully compromised will begin sending traffic to 61.188.39.175 ( http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080313 ).

Last Updated: 2008-03-15 17:23:13 UTC - "...The 2117966.net (please, do NOT visit that site) campaign affected approximately 13,800 ASP pages. No php pages.

>>> This -other- attack is reported to have affected around 200,000 phpBB pages. It's a bigger attack and very important, you should read Dancho's blog, it has IP addresses and domains to look for in your logs as well as what traffic an infected system will generate. If you're a website administrator, also take a close read of his 04-MAR-2008 entry:
http://ddanchev.blogspot.com/2008/03/zdnet-asia-and-torrentreactor-iframe-ed.html
Pay particular attention to how they're inserting the code into the site (from Dancho's Blog):
"(The sites) themselves aren't compromised, their SEO practices of locally caching any search queries submitted are abused. Basically, whenever the malicious attacker is feeding the search engine with popular quaries, the sites are caching the search results, so when the malicious party is also searching for the IFRAME in an "loadable state" next to the keyword, it loads. Therefore, relying on the high page ranks of both sites, the probability to have the cached pages with the popular key words easy to find on the major search engines, with the now "creative" combination of the embedded IFRAME, becomes a reality if you even take a modest sample, mostly names."

This is important. It's not obvious to me how to fix the problem..."

SQL-injection attacks...

FYI...

- http://www.symantec.com/avcenter/threatcon/learnabout.html
(03.20.2008) - "...DeepSight Threat Analyst Team is currently monitoring a number of ongoing mass SQL-injection attacks that are manipulating victim servers to host malicious content to browsing clients.
- A number of these attacks are currently being carried out. One attack involves a failure to sanitize cached search results, allowing malicious HTML to be injected into search result pages. This has affected a number of high-profile sites and has been thoroughly documented by the researcher who originally discovered the attacks: ( http://ddanchev.blogspot.com/2008/03/more-high-profile-sites-iframe-injected.html )
- Another attack is currently targeting servers running vulnerable ASP scripts that can be exploited through SQL injection to host malicious HTML code. The injected code references a malicious script... which in turn injects an IFRAME into the page to redirect users to a site that tries to exploit various known and patched vulnerabilities. This attack is believed to have affected over 15,000 pages, but the number of unique servers compromised may be far less.
- Yet another large-scale attack involving SQL injection is targeting servers running PHPBB. This attack injects HTML code that loads a malicious JavaScript file from 'free.hostpinoy.com'. Reports indicate that this attack is much more prevalent, perhaps because of the ubiquity of PHPBB. Over 150,000 pages may be affected. Note again, however, that the number of unique servers compromised may be far less. In previously observed cases, over 5000 pages have been affected on a single domain. At the time of writing, most of the sites hosting the exploits or malicious JavaScript are down, but they may come back online at any time. Administrators are advised to audit their web services to ensure that no exploitable flaws exist in the publicly exposed scripts and that the latest versions are installed. Network admins are advised to block access to '2117966.net' and 'free.hostpinoy.com' at the gateway.

Clients are advised to browse using strict security policies. The following list of strategies may prevent or hamper an attack:
- Run browser software with the least privileges possible.
- Disable JavaScript, IFRAMEs, and ActiveX controls.
- Enable OS security mechanisms such as Data Execution Prevention (DEP).
- Ensure that browsing software is up to date.
- Filter all web activity through security products such as an Intrusion Prevention system."

EDIT/ADD: http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080320
20 March 2008 - "...In our last post we mentioned the several thousands of websites that were SQL injected to reference malicious JavaScript code on 2117966.net. At the time we were actually just taking an educated guess that this was the result of SQL injection. However, it has since been confirmed... It turns out this is the same IP address that carried out the SQL injection attacks related to the uc8010.com incident*. Not very subtle are they? You might want to keep an eye out for the IP 202.101.162.73"

4,500 different domains... 150 new domains each day

FYI...

- http://www.sophos.com/security/blog/2008/03/1243.html
30 March 2008 - "...Our data for all records processed since March 1st 2008 (so approximately 4 weeks worth of data). The data reveals almost 11,000 pages compromised with Troj/Unif-B, split across approximately 4,500 different domains. That is a fair amount of activity, approximately 150 new domains each day (and this is just what we are seeing)... For the 4,500 compromised domains, these targets fall into two categories:
1. additional attack sites. Some other site which hits the victim with exploits.
2. redirect or ‘control’ sites. Some other site, controlled by the attacker, which can be used to direct traffic (as discussed previously). Typically, these sites direct victims to one of several other attack sites (though there may be several redirects in use). There a number of prominent attacks visible in the data:
* ~30% use a renowned attack site for installing various malware including Mal/Dropper-T, Mal/EncPk-CM and Mal/EncPk-CO.
* Tibs: over 10% are redirect sites under the control of a large and well coordinated group. Numerous domains have been used by this group in recent months to install a variety of Dorf, Tibs and other malware.
* Zbot: almost 10% load exploits intended to install a member of the Mal/Zbot family.
* Gpack: approximately 5% point to a single GPack attack site, which installs malware detected as Mal/Emogen-Y.
....something recently talked about by Roger Thompson, on the Exploit Prevention Labs blog*... As speculated previously ( http://www.sophos.com/images/sophoslabs-blog/2008/02/map.png ), it is not unlikely that these sites could be used to make money by selling ‘traffic flow’ (attackers essentially paying for victims to be directed to their attack sites for a period of time)..."

March 28, 2008 - "...It's just javascript, and thus far, we've only seen one exploit come out of it ... a mouldy, old MS06-014, although we expect there are more than that... while there is clearly more than one set of Bad Guys involved, most of them seem to being hosted by the same ISP, because the exploit IPs are similar..."

Malicious websites/code - UN and UK gov't sites compromised

FYI...

04.22.2008 - "...malicious JavaScript injection that compromised thousands of domains at the start of this month, just 2-3 weeks ago. The attackers have now switched over to a new domain as their hub for hosting the malicious payload in this attack. We have no doubt that the two attacks are related... In the last few hours we have seen the number of compromised sites increase by a factor of ten. This mass injection is remarkably similar to the attack we saw earlier this month. When a user browses to a compromised site, the injected JavaScript loads a file named 1.js which is hosted on hxxp ://www.nihao[removed].com The JavaScript code then redirects the user to 1.htm (also hosted on the same server). Once loaded, the file attempts 8 different exploits (the attack last April utilised 12). The exploits target Microsoft applications, specifically browsers not patched against the VML exploit MS07-004 as well as other applications. Ominously files named McAfee.htm and Yahoo.php are also called by 1.htm but are no longer active at the time of writing. There are further similarities too between the two mass attacks. Resident on the latest malicious domain is a tool used in the execution of the attack. An analysis of that tool can be found in the ISC diary entry here*... It appears that same tool was used to orchestrate this attack too. When we first started tracking the use of this domain, the malicious JavaScript was still making use of hxxp ://www.nmida[removed].com/... Sites of varying content have been infected including UK government sites, and a United Nations website as can be seen by the Google search...

Hundreds of thousands of SQL injections
- http://isc.sans.org/diary.html?storyid=4331
Last Updated: 2008-04-24 19:36:50 UTC - "UPDATE.
It is recommend that you block access to hxxp :/www .nihaorr1.com and the IP it resolves to 219DOT153DOT46DOT28 at the edge or border of your network.
1.js is the file they are currently injecting. That could change and has been injected into thousands of legitimate websites. Visitors to this website are “treated” to 8 different exploits for many windows based applications including AIM, RealPlayer, and iTunes. DO NOT visit sites that link to this site as you are very likely to get infected. Trendmicro named the malware toj_agent.KAQ it watches for passwords and passes them back to contoller’s ip.
The crew over at shadowserver has published additional information related to SQL injected sites. They included the botnet controllers IP address 61.188.39.214 and a content based snort signature for the bot control traffic that is not ip dependent. The bot controller is alive and communicating on port 2034 with some infected clients at this time.
http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080424
http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080313
They have hit city websites, commercial sites and even government websites. This type of injection pretty much null and voids the concept of “trusted website”. or "safe sites".
The register covered it stating their search returned 173k injected results:
http://www.theregister.co.uk/2008/04/24/mass_web_attack/
The number I received doing the same search was 226k. Those are not all unique websites. Many sites got hit more then one time.
Lou a self described “accidental techie” has been discussing it as they have been reinjecting this into his database/website “every other day”. http://www.experts-exchange.com/Database/MySQL/Q_23337211.html

FYI... (DO NOT visit the the sites mentioned in the commentary as you are very likely to get infected - BLOCK them, but don't go there.)

- http://www.f-secure.com/weblog/archives/00001427.html
April 24, 2008 - "...As more and more websites are using database back-ends to make them faster and more dynamic, it also means that it's crucial to verify what information gets stored in or requested from those databases — especially if you allow users to upload content themselves which happens all the time in discussion forums, blogs, feedback forms, et cetera. Unless that data is sanitized before it gets saved you can't control what the website will show to the users. This is what SQL injection is all about, exploiting weaknesses in these controls... It finds all text fields in the database and adds a link to malicious javascript to each and every one of them which will make your website display them automatically. So essentially what happened was that the attackers looked for ASP or ASPX pages containing any type of querystring (a dynamic value such as an article ID, product ID, et cetera) parameter and tried to use that to upload their SQL injection code. So far three different domains have been used to host the malicious content — nmidahena .com, aspder .com and nihaorr1 .com. There's a set of files that gets loaded from these sites that attempts to use different exploits to install an online gaming trojan. Right now the initial exploit page on all domains are unaccessible but that could change. So if you're a firewall administrator we recommend you to block access to them.
So what should you do?
- First of all, search your website logs for the code above and see if you've been hit. If so, clean up your database to prevent your website visitors from becoming infected.
- Second, make sure that all the data you pass to your database is sanitized and that no code elements can be stored there.
- Third, block access to the sites above.
- Fourth, make sure the software you use is patched...
- Fifth, keep your antivirus solution up-to-date."

(Note: per http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080424 : "...nmidahena.com... domain has since been killed off and looks like our attacker has moved on to some new ones... it most likely won't take too long for others to catch on and possibly conducting even more nefarious activities. If your site has fallen victim to one of these attacks, it's not just important you remove the offending injections, but it's even more important you fix the SQL injection attack vector. If you do not, your website will continue to be vulnerable to similar or worse attacks.")

Web pages are infected with the iFrame code by looking for a specific code string in the source code of the Web page associated to an iFrame tag..."

April 24, 2008 - "...So far three different domains have been used to host the malicious content
— nmidahena .com*, aspder .com and nihaorr1 .com.
There's a set of files that gets loaded from these sites that attempts to use different exploits to install an online gaming trojan. Right now the initial exploit page on all domains are unaccessible but that could change. So if you're a firewall administrator we recommend you to block access to them..."

SQL Injection Worm on the Loose

FYI...

- http://isc.sans.org/diary.html?storyid=4393
Last Updated: 2008-05-07 05:12:53 UTC - "A loyal ISC reader... wrote in to point us at what looks to be a SQL Injection worm that is on the loose. From a quick google search it shows that there are about 4,000 websites infected and that this worm started at least mid-April if not earlier. Right now we can't speak intelligently to how they are getting into databases, but what they are doing is putting in some scripts and iframes to take over visitors to the websites. It looks like the infection of user machines is by Real Player vulnerabilities that seem more or less detected pretty well. The details, the script source that is injected into webpages is hxxp ://winzipices .cn /#.js (where # is 1-5). This, in turn, points to a cooresponding asp page on the same server. (i.e. hxxp :// winzipices .cn/#.asp). This in turn points back to the exploits. Either from the cnzz .com domain or the 51 .la domain. The cnzz .com (hxxp ://s141 .cnzz .com) domain looks like it could be set up for single flux, but it's the same pool of IP address all the time right now. hxxp ://www .51 .la just points to 51la .ajiang .net which has a short TTL, but only one IP is serving it.
Fair warning, if you google this hostnames, you will find exploited sites that will try and reach out and "touch" you... even if you are looking at the "cached" page. Proceed at your own risk.
UPDATE: We're also see this website serving up some attacks in connection with this SQL Worm
(hxxp ://bbs .jueduizuan .com)"

New SQL Injection Attacks and New Malware: winzipices .cn

FYI...

- http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20080507
7 May 2008
"Warning: We strongly suggest that readers NOT visit websites mentioned as being behind the attacks discussed. They should be considered dangerous and capable of infecting your system.

As predicted, the attacks against ASP and ASP.NET pages via SQL injection have continued. This time the domain name "winzipices.cn" is in the spotlight. It has managed to find itself in the source of over 4,000 pages according to Google. ISC has also has a short diary today mentioning this attack here. It turns out this is also something we have been taking a look at now for a few days. With that being said, we would like to share some information that can help protect end users and organizations. It would appear that our attackers in this instance are taking advantage of the same issues we have discussed in some of our recent postings. However, we do know that the malware and malicious file trail here are different than the last few attacks. If your websites has been hacked or you are visiting a hacked website, you will find something like this in your HTML source in the page you visit:
"<script src=hxxp ://winzipices .cn/ 5.js></script>"
It appears that 1.js, 2.js, 3.js, and 4.js are also present. Each of these files in turn have hidden iframes...

Protection & Detection
As always we recommend that you block access to the malicious domains and sites. Using a content filter, changing DNS entries, and blocking IP addresses are all valid methods. Of course being up-to-date on your patches can also go a long way. Here's a quick recap of the malicious sites/IP addresses involved in this attack:
-winzipices.cn [60.191.239.229]
-61.188.38.158
-61.134.37.15
Note that blocking by IP address could potentially block other legitimate pages on the host (not likely in this case). It's also generally only valid or helpful for a short period of time as attackers frequently change both IP addresses and domain names."
