Our sensors recently picked up a Web site infection, affecting the Web site of the Ministry of Micro And Medium Enterprises (MSME DI Jaipur). And although the Black Hole Exploit Kit serving URL is currently not accepting any connections, it’s known to have been used in previous client-side exploit serving campaigns.

Let’s profile the campaign, list the malicious URLs, associate them with previously launched malicious campaigns, and provide actual MD5s for historical OSINT preservation/attribution purposes.

The Black Hole Exploit Kit redirecting URL that’s currently embedded at the Indian government Web site is currently not accepting any connections. However, we know that on 2012-07-03 08:04:36, it was responding, and was indeed served malicious content.

Sample redirection chain:
hxxp:// -> hxxp:// -> hxxp://

Upon successful client-side exploitation back then, it dropped MD5: 770cc2e2a184eaad0d79716f0baf9e48 - detected by 40 out of 46 antivirus scanners as Trojan-Ransom.Win32.Birele.vjr; PWS:Win32/Fareit.gen!C.

Once executed, the sample created the following Registry Key on the affected hosts:

As well as the following Registry Value:
[HKEY_CURRENT_USERSoftwareWinRAR] -> HWID = 7B 42 37 36 33 44 31 31 31 2D 41 45 45 37 2D 34 30 46 36 2D 41 38 41 31 2D 35 36 33 44 46 41 32 37 41 32 34 37 7D

It then downloaded additional malware from:

MD5: 76B2A3832CE39F81887FC3375AF60FC5

With the samples back then, phoning back to ( In 2012, the same IP was also seen in a malvertising campaign.
