Research Roundup: Less Spam, More Mobile Malware and a Third of all Site Traffic Poses a Threat
2011 was a record-setting year for attacks on smart phones and tablet computers.
Content scrapers, hacking tools, content spammers and an array of other “spies” make up nearly a third of all traffic at most websites, according to a new report.

Fake AV dropped considerably from Q3, while AutoRun and password-stealing Trojan malware show modest declines.
Companies can’t keep up with malware threat. Ninety five percent of all enterprises are exposed to malware on a daily basis, according to security firm FireEye. The volume and sophistication of threats is outpacing businesses’ ability to counteract these risks despite an estimated $20 billion spent annually on IT security.
