Research from Sophos has shown that a single piece of Malware, identified by them as JSRedir-R, is responsible for 42 percent of Web page hijackings online. A test running from May 6 until May 13 showed that JSRedir-R was found six times more often than its closest rival, Mal/Iframe-F.

JSRedir-R [Virus Total] is found on legit sites that have been hijacked (computer virus) by criminals to propagate infection. It’s the direct result of exploitation of common code flaw found in PHP driven websites, including outdated Word Press blogs, PHP-based forum scripts, image galleries, and various other Web-based applications.

Because JSRedir-R is embedded into a compromised site by injecting its code into PHP files, JavaScript files (towards the end of the infected JS file), or by hidden Iframe code, the best way to avoid falling victim is to secure your site’s code. This is easier said than done.

JSRedir-R embeds itself within legitimate but poorly secured websites, and loads malicious programs from third-party sites on to a user’s computer without their knowledge. This gives hackers and cybercriminals a “back door” in to the machine and presents them with the opportunity to steal passwords, identity details and financial information.

No-one should be in any doubt that the web is still the main vector of attack for cybercriminals, and this new threat suggests this situation isn’t going to change anytime soon. The problem is that too many computer users still think there’s no danger in surfing the web, but with legitimate sites often falling victim to these attacks, it’s time to wake up.

Hackers (computer virus) won’t stop targeting the web as it’s proving a successful way for them to spread their infections. To combat this, it’s essential to scan every website for malicious code before visiting it.Security experts have warned web users to ensure their antivirus software is up to date in order to protect themselves against the malware threat.
