Espionage kit "Regin" dominates today's news. Symantec published a lengthy report on the stealthy, persistent, advanced malware over the weekend. Regin is being widely compared to Stuxnet, but (reflexive journalistic comparison to familiar stories aside) any similarity appears to lie not in functionality, but rather in sophistication and tentative attribution. As F-Secure notes, "for a change" the malware doesn't appear to originate in Russia or China, and other observers are talking about " Western intelligence services" — possibly the US and Israel. F-Secure notes that it found a version of Regin on a northern European Windows server in 2009. Symantec (which notes that it didn't name the malware, "Regin" being a malign actor in Norse mythology) thinks the kit may have been in active use as far back as 2006.
Other notes on cyber war include US concerns about China (as NSA Director Rogers's warnings about critical infrastructure sink in) and (again) Iran, and Indian worries about a Pakistani-ISIS link. ISIS continues its activity in social media on several fronts, but other instances of "crowd-sourced war" crop up elsewhere, notably in Ukraine. A demotically titled op-ed in the Verge argues that the damage done in cyber war is essentially collateral; perhaps cyber war is impossibly discriminate.
Anonymous is causing trouble in Canada with hits on official site in Toronto and Ottawa. The proximate inspiration is apparently a teen's arrest for swatting: Anonymous objects to the arrest.
