Mal/JSRedir-H is a malicious web page-based redirect that occurs automatically and forces your browser to load hostile content – currently including Blacole-based drive-by-download exploits. SpywareRemove.com malware researchers have found that Mal/JSRedir-H attacks are being promoted by fake CNN news articles that are distributed through social network sites and spam. Unprotected contact with Mal/JSRedir-H can result in the installation of a Trojan on your PC that may be used for attacks such as opening a backdoor, disabling security software or stealing personal information. Because social engineering techniques are emphasized in current Mal/JSRedir-H strategies, SpywareRemove.com malware experts recommend that you examine links to other websites carefully and use anti-malware software with web-browsing protective features to protect your PC from Mal/JSRedir-H – and, if necessary, remove Mal/JSRedir-H's ultimate payload from your computer.

From News Headlines to Updates to Trojans with Mal/JSRedir-H Sandwiched in the Middle

Websites that host Mal/JSRedir-H attacks are promoted by fraudulent e-mails that are formatted to look identical to CNN 'breaking news' notifications. These e-mails are noteworthy for including references to the ongoing US presidential campaign, complete with tantalizing hints as to the rising status of Mitt Romney (hitherto the race's underdog candidate). Other fake articles that are included so far mention a series of meningitis-related deaths and unusual acts of terrorism in, all of places, Oklahoma. SpywareRemove.com malware analysts also warn that similar attacks are likely to target victims through non-e-mails means like social network websites and instant messengers.

Clicking any of the 'article' links, instead of giving you a helping of CNN news, will direct you to a malicious site that exploits JavaScript in the form of Mal/JSRedir-H. This exploit redirects you to a second site, with current Mal/JSRedir-H attacks being used to expose victims to the Blackhole Exploit Kit – a configurable attack package that installs malware. For the criminals behind these attacks, the ideal victim is someone who hasn't updated any of their software, which allows BEK to install a PC threat automatically.

What Happens When You Protect Your PC More Effectively than Mal/JSRedir-H Anticipates

Unusually, current versions of BEK that are promoted by Mal/JSRedir-H also have been seen using social engineering attacks as a fallback tactic when normal drive-by-downloads are unable to do the job. These attacks encourage you to install malicious software that's disguised as a fake software update – usually for Adobe software. SpywareRemove.com malware analysts note that this is some of the first evidence of BEK being used for social engineering attacks instead of simple drive-by-downloads that install malware without the victim's consent. The download prompt may occur without you clicking the associated link (which is embedded in a criminal site that's designed to look like Adobe's own website), but still requires your permission to proceed.

Awareness of the online threats currently targeting PC users can help you to avoid social engineering-related tricks that are used both by links to Mal/JSRedir-H and content that Mal/JSRedir-H promotes. Disabling JavaScript when it's not required by trustworthy sites, as SpywareRemove.com malware experts recommend, can also prevent Mal/JSRedir-H's redirect from occurring. However, if you think that you've been exposed to successful Mal/JSRedir-H attacks, anti-malware software should be used to remove payloads related to Mal/JSRedir-H as soon as possible.
