QUOTE: Fake Anti-Virus isn’t enough, now we also have to contend with fake Microsoft reps! This scam has been going on for a while, but continues to be rampant, which suggests that it is quite successful for the bad guys. ISC reader Fred received such a call earlier today. The caller claimed to be from the “Tech department of Windows” and asked Fred to open the event viewer via run command, to check for errors or warnings. Of course there were some errors (it is Windows, after all :-), but the alleged techie then theatrically exclaimed “You indeed have the deadly errors” .. and proceeded to ask Fred to connect to a malicious site and launch a remote desktop app. Fred, savvy security guy that he is, went there with Firefox and Noscript, and while Fred was still launching Wireshark to capture the next steps, the alleged Windows techie got cold feet, and hung up.

QUOTE: It’s still a mystery how many MasterCard and Visa customers will be affected by the recent breach at a credit card payment processor.

Sources told Krebs the breach was “massive” and may involve more than 10 million records.

Facebook logins toxic for employers, violate security and privacy principles
QUOTE: Attention CEOs and HR Managers: Facebook login credentials belonging to current or prospective employees are not something that any employer should request, use, or posses. Why? Apart from the violation of security and privacy principles? The risks far outweigh any benefit you imagine you could gain by logging into a social media account that does not belong to you, even if you have persuaded the account owner to give their consent. The practice of asking current or future employees for their Facebook credentials is not only a serious risk for employers, it is one of the most unpleasant HR stories that I’ve encountered …

Trustworthy Computing Next: Building Trust in a Connected World
QUOTE: From the beginning, Trustworthy Computing’s mission was billed as a long-term journey. As Microsoft marked the 10-year milestone of TwC last month, we also looked forward and recognized that evolving IT models and societal changes have made the relentless pursuit of TwC more important than ever. Today at the RSA Conference 2012, I’m providing my vision for Trustworthy Computing Next within a keynote and sharing a new white paper.
There are three major forces of change. First, with a proliferation of devices, services, and sensors, people are excited about the potential of the cloud and big data. … Second, as our dependency on IT has grown, governments have become increasingly active in Internet affairs. … Finally, the threat landscape continues to evolve. Opportunistic threats have been supplemented by attacks that are more persistent and determined.
In this new world, each and every machine, application, data or person may be helpful or harmful, innocuous or dangerous. The Web we live in today is no longer about bilateral relationships; we are connected in new ways where an individual and an organization may have no direct relationship at all, even as they share data or take on IT dependencies. With lack of transparency into these relationships, dependencies, and data flows, it can be hard to make intelligent trust decisions.
