Google search to find Compromised Google Images

Since few weeks, we heard about google image searches infected by Search Engine Optimization (SEO) poisoning. Many legitimate sites linked to scareware trojans and exploits via Google Image results are discovered every day. Many of these sites would otherwise be considered as safe but they've been compromised by a hack of some sort.

Do not search for inurl:wp-images unless you are using test network or use Google SSL as the poisoned SEO sites will only attack if visited from http://www.google.com.

Lets see, walk with present to see the future.

Propagating Malware via legitimate websites

Few years ago, In 2006 and earlier, “No one ever thought of spreading malware via legitimate websites.” Popular Infection Vectors (before 2006) are:

• Go to system and install a malicious piece of code (Rarely heard of it or very few cases),


• Supply malware in USB drives with autorun (pretty common and still effective, spreading malware enormously)


• Distribute malware as an email attachment (pretty common and still effective unfortunately)


• Convincing users to download legitimate looking software but actually MALWARE (providing direct link in email, chat or other mechanism)

Malware authors are shifting their focus from traditional desktop bases attack methodology to the new emerging dynamic and user interactive web applications for spreading malware.

Drive-by-download. Drive-by-download is working covertly, which make it difficult to suspect or detect. Since last 3-4 years, awareness in web administrators and security professionals regarding server side vulnerabilities has increased. Eventually, they are doing their job quite nicely, securing all six OSI layers except the last and most vulnerable layer- "Application layer".


Motive of malware authors:

• Access on the infected computer


• Steal user credentials, banking or other passwords


• Use as a launching pad for further attacks


• Install more sophisticated malwares/viruses


• Gain chain of access to corporate networks via VPN etc for which user or user's system is allowed for.

Web 2.0 functionalities are also being effectively used for controlling botnet.

Rouge Antivirus AVG-Antivirus-2011

Again, the Rouge Antivirus Vendors are on rise. This is not just happening this year, actually this is noticed during the begining of year. Check my last year's blog posting "Beaware of Security Essentials 2010, A Rouge Anti-Virus" for the similar Rouge antivirus product.

This time they, "Rouge Antivirus Vendors", came up with "AVG -Antivirus 2011", which is obviously fake. Rouge Antivirus Vendors are impersonating the legitimate AVG antivirus product and replicating the GUI and trademark symbols of AVG antivirus.

Just have a look to the Rouge antivirus "AVG -Antivirus 2011" shortcut icon:

Once installed on system, It blocks other programs running on the computer, hijacks web browsers and displays fake security alerts, threats and risk. This kind of fake security warning may be observed.

It also reports false infections found on your computer and ask to purchase a full version to remove them.

This is the warning page displayed by Rouge AVG-Antivirus 2011, which says, this is trial version having limited functionality and in-order to disinfect your system, you need to purchase the full version of Rouge AVG-Antivirus 2011. And they will lead you to the make some financial transactions.

Please do care about this threat, do not panic and pay. For removal please follow the steps mentioned below:

• Disable System Restore Temporarily
• Update the latest virus definitions for your existing Antivirus
• Reboot computer in Safe Mode
• Run a full system scan and clean/delete all infected file(s)

Countermeasures:

• Use caution while clicking on links to Web pages
• Keep up-to-date Antivirus and Antispyware signatures
• Be cautious while opening e-mail attachments
• Keep up-to-date patches and fixes on the operating system and application software

A List of rouge anti-virus /anti-spyware products can be found here.

Zero Day Vulnerabilities in Windows

Apologies, for writing after so long,

What brings me to write in here is, the issues seen early this year, two critical vulnerabilities in Microsoft. Almost all flavours of Microsoft operating systems are affected. And the worry is both issues are Zero day and no patch is available from the vendor, off-course some workarounds are there, follow the references.

First issue discovered is in Windows Graphic Rendering Engine (GRE), Issue is caused due to some stack overflow vulnerability in "CreateSizedDIBSECTION()" function in "shimgvw.dll" module. Attackers could exploit this vulnerability by luring users to view a malicious crafted thumbnail image.

Second issue is in Microsoft Internet Explorer 8 (IE8), almost all different flavours of MS has this latest browser. Issue is caused due to use-after-free error in mshtml.dll when processing circular references between JScript objects and Document Object Model (DOM) objects. Attackers can exploit this vulnerability by luring users to visit a crafted webpage or website.

After exploiting any of these vulnerabilities, attackers can take control of affected systems.
