Rogue iFrame Injected Web Sites Lead to the AndroidOS/FakeInst/Trojan-SMS.J2ME.JiFake Mobile Malware

A currently ongoing malicious campaign relying on injected iFrames at legitimate Web sites, successfully segments mobile traffic, and exposes mobile users to fraudulent legitimately looking variants of the AndroidOS/FakeInst/Trojan-SMS.J2ME.JiFake mobile malware.

Let’s dissect the campaign, expose the domains portfolio currently/historically known to have been involved in this campaign, as well as list all the malicious MD5s known to have been pushed by it.

iFrame injected domains containing the mobile traffic segmentation script parked on the same IP: –

Sample mobile malware MD5s pushed by the campaign:
MD5: e77f3bffe18fb9f5a1b1e5e6a0b8aaf8

Parked on the same IP ( are also the following domains participating in the campaign’s infrastructure:

The following malicious mobile malware MD5s are known to have phoned back to the same IP in the past:

MD5: aefdbdee7f873441b9d53500e1af34fa

What’s also worth emphasizing on is that we’ve also got a decent number of malicious Windows samples known to have phoned back to the same IP in the past, presumably in an attempt by fellow cybercriminals to monetize the traffic through an affiliate program.

Thanks to the commercial availability of DIY iFrame injecting platforms, the current commoditization of hacked/compromised accounts across multiple verticals, the efficiency-oriented mass SQL injection campaigns, as well as the existence of beneath the radar malvertising campaigns, cybercriminals are perfectly positioned to continue monetizing mobile traffic for fraudulent/malicious purposes.
