Here is another alert from Sophos about malware laden emails masquerading as emails from legitimate companies.  This time the bad guys are sending out Groupon “dicount” (sic) codes that really just give your PC a nasty rash of the Trojan horse variety.

Many devices including smartphones and tablets are shipping now or will be available soon with a feature called NFC or Near Field Communications.  We have seen this already in contactless credit card products such as PayPass and PayWave.  Soon you will be able to use your smartphone to make purchases as well.

In an article on Sophos, the question was posed “Is security training a waste of time?”  There were some examples of training with poor outcomes.  80% of West Point cadets given 4 hours of computer security immediately fell for a test phishing scam.   Employees at internet security firm RSA opened an infected XML attachment to an email that allowed their “secure” network to be breached by real-life hackers.  At the end of the article, it is suggested that ...

I recent survey by several leading software manufactures found that only 40% of users accepted alerts requesting them to download an install an upgrade, update, or security patch, even when the updates are free of charge.  The reasons given most often were:
