"The Jester" Threatened To Expose Anonymous Members and Al Qaeda Supporters

A hacker with the name The Jester(th3j35t3r) has threatened to leak information regarding members of Anonymous and supporters of Al Qaeda. He claims that he has access to their smartphones and has extracted sensitive information including address, call logs, message logs and others from the infected devices. Also note that this hacker has caused trouble for other hackers before.

The hacker used his twitter account to accomplish his mission. He changed his profile picture to a QR code which was kept for five days last week. When users scanner the code with their smartphones, a new link opened in the browser and a message "BOO!" was showed. The hacker actually exploited a webkit vulnerability in the engine which powers the browser in Android and iOS. He claimed to have compromised the devices of 500 people out of 1,200 individuals who scanned the QR code.

The Jester said that he had modified the exploit code slightly and still managed to see a 40 percent success rate though the security hole was fixed in most browsers on 2010.

He said in his tweet, "EVERYONE else without exception was left totally 'untouched' so to speak. This was a Proof of Concept QR-Code based operation against known bad guys, the same bad guys that leak YOUR information, steal YOUR CC nums, and engage in terror plots around the world. I do not feel sorry for them. In the interests of convenience I will be taking the liberty of uploading the captured bad-guy data in a signed PGP encrypted file to a suitable location very soon. How’s that for 'lulz'?"

A couple of days ago The Jester posted a text file, which he claimed as the "resulting raw dump of the verbose output log from this exercise," on MediaFire which size was 143.08 MB. It was encrypted with his PGP Public key, so it was impossible to read that text file without the public key. We are still unclear about the attack. We won't know until he releases the password to the aforementioned file.
