October was named European Month of Cyber Security and because of that, many events intended to raise cyber security awareness (such as Security Fest in Prague) were held during the 30 day period. Unfortunately, October has seen just as many new developments on the proverbial “dark side” of cyber security. One of these was a widely followed theft of personal data (including credit card numbers) of up to four milion customers of a British telecommunication service provider TalkTalk.

One of the most important information related to cyber security pertains to August release of a patch for the Stagefright vulnerability, to which almost all versions of the Android OS from versions 2.2 to version 5.1 are vulnerable. The existence of Stagefright had been made public at the end of July and it is estimated that vulnerable device number in hundreds of millions. The vulnerability enables the attacker to cause arbitrary code execution by sending a specially crafted MMS.
