An anonymous reader writes "Having been targeted by malware in the past, anti-government protesters in Bahrain are now being hit hard by IP tracking attacks, according to a researcher. Bill Marczak, of Bahrain Watch and Citizen Lab, who is putting together a report on the attacks, said it appeared Bahrain officials had been masquerading as fake activists, sending obfuscated URLs to targets to learn their IP address. The next step is to take the IP address and the time of the click to the relevant ISP to find out who the user is. Then all sorts of things can happen. 'People who have clicked on these links have suffered various types of consequences ranging from having their houses raided and being charged for saying insulting things about the king on Twitter, or losing their jobs,' says Marczak. 'It looks like, from our investigation so far, in one case, the government did lock up the wrong person.'"
