The Jester (also known by the leetspeak handle th3j35t3r[1]) is a self-described gray hat[2] "hacktivist"[3] who is allegedly responsible for attacks on WikiLeaks,[4] 4chan,[5] Iranian President Mahmoud Ahmadinejad,[4] and Islamist websites.[6] He claims to be acting out of American patriotism.[7] The Jester developed and uses the denial-of-service (DoS) tool known as "XerXeS".[4] One of The Jester's habits is to tweet "TANGO DOWN" on Twitter whenever he successfully takes down a website.[5]

The Jester had stated that he was a former soldier and had served in Afghanistan and elsewhere.[8] A former defense operative claimed that The Jester was a former military contractor involved in US Special Operations Command projects.[7]

The Jester claims to have originally developed his DoS script as a means to test and harden servers.[9] After learning from an article that Jihadists were using the Internet to recruit and coordinate terror cells, The Jester resolved to disrupting online communications between Jihadists.[10] He weaponized his script and created a front-end known as "XerXeS" in order to solve the script's usability problems.[9]

On January 1, 2010, The Jester began a campaign against Jihadist websites. His first target was alemarah.info, which was the Taliban's website at the time.[11][12][13]

On November 28, 2010, The Jester posted several tweets claiming to be responsible for the downtime WikiLeaks was experiencing.[5] He justified his alleged attacks by claiming that WikiLeaks was "attempting to endanger the lives of our [US] troops, 'other assets' & foreign relations."[4] In retaliation to The Jester's reported efforts hacktivists including a group named Anonymous in support of WikiLeaks were reported as temporarily disrupting the website of MasterCard as well as attacking websites of Amazon and Paypal.[14]

On December 28, 2010, a DoS attack targeted 4chan.org. On that same day, The Jester tweeted "4chan.org — that looks like a TANGO DOWN (not) maybe you guys pissed off the wrong person trying to (wrongly) ID me?"[5] This tweet is believed to be a reference to 4chan's claims that The Jester was a man from Montana.[5][15]

On February 21, 2011, The Jester began a DoS attack on several sites belonging to the Westboro Baptist Church.[16]

In June 2011 The Jester vowed to find and expose members of LulzSec.[17] He has attempted to obtain and publish the real world personally identifiable information of key members, who he describes as "childish".[18] On June 24, 2011, he claimed to have revealed the identity of LulzSec leader Sabu as an information technology consultant possibly from New York City.[19]
