Over the past few months, Google has been busy squashing security vulnerabilities in its popular Android mobile operating system, but many remain undiscovered, and some can be easily exploited.

Hacking back, whether as part of an active defense strategy or a threat intelligence effort, is a controversial practice that many security firms and experts officially advise against.

Misty-eyed old-timers are mourning the passing of one of the world’s most elegant encryption algorithms. RC4 was designed by Ron Rivest in the late 1980s.

Perhaps due to the algorithm’s simplicity (you can keep it in your head), it leaked out into the Internet in the 1990s where it became the de facto TLS bulk encryption protocol for over a decade.

A point-of-sale (PoS) malware that went largely undetected for the past several years has been analyzed by researchers at Trustwave.Dubbed by the security firm “Cherry Picker,” the threat has been around since at least 2011, but it managed to stay under the radar thanks to its sophisticated functionality and use in highly targeted attacks.

Most of the top 200 and top 100 applications available for Android users via the Google Play store can be decompiled and reverse engineered, a new report from mobile application security solutions provider SEWORKS claims.
