Britain's GCHQ's motive in intercepting G20 diplomats' messages is said to have been the traditional one: gain the UK a negotiating advantage. In the US, Apple and Yahoo describe their involvement in NSA surveillance. Whoever's behind the NetTraveler cyber espionage campaign is now using PRISM stories as bait.

Unrest in Brazil and Turkey is accompanied by hacktivist exploits. Indian bank accounts are hacked (and robbed) from Greece.

A Tactical Network Solutions researcher says he'll reveal significant surveillance camera vulnerabilities at Black Hat. A new iFrames obfuscation tool is offered for sale on the cyber black market, and more malware is hiding its activity in peer-to-peer communications. Old, unpatched SAP deployments are found to render many business systems vulnerable to exploitation.

Companies seek better employee vetting as they react to the PRISM affair, but lawyers caution too-enthusiastic exploration of potential hires' social media presence risks violation of anti-discrimination laws.

President Obama has now publicly defended NSA surveillance programs. More details of how such surveillance might work—and fresh suspicions about its scope—surface.

The US Department of Homeland Security (DHS) draws this lesson from the PRISM affair: it wishes it could do what the NSA did. (Also, the Public Affairs Council thinks DHS should do more to combat conspiracy theories. Similar cognitive dissonance appears in Canada, whose Privacy Commissioner decides, amid concerns about government overreach into citizens' privacy, that tightening privacy regulations on private companies is of first importance.)

Dutch and Belgian police catch smugglers betrayed by their own shipment-tracking hacks.
