U.S. Military Intelligence Analyst Arrested for Data Leakage

This Wired article discusses a U.S. Army intelligence analyst being arrested for leaking classified and other sensitive information to Wikileaks. A quote from the Wired article:“I would come in with music on a CD-RW labeled with something like ‘Lady Gaga’, erase the music then write a compressed split file,” he wrote. “No one suspected a thing and, odds are, they never will.”“[I] listened and lip-synced to Lady Gaga’s ‘Telephone’ while exfiltrating possibly the largest data spillage in American history,” he added later. ”Weak servers, weak logging, weak physical security, weak counter-intelligence, inattentive signal … Continue Reading

Preparing for Apple Mac Malware

This SANS ISC article (http://isc.sans.org/diary.html?storyid=8890) got me thinking again about the reality of Mac malware. What are people using for AV scanning for Mac executables at their web and mail gateways? As Macs increasingly make their way in the enterprise and Apple continues to improve its market share, I assume that eventually we will need to supplement host-based AV scanning on the Macs with gateway-based AV defensive layers – just like we did to protect our Windows endpoints.
