Topiary, real name Jake Leslie Davis, born October 27th, 1992, is a former hacker. He has worked with Anonymous, LulzSec, and other similar hacktivist groups." He was an associate of the Internet group Anonymous, which has publicly claimed various online attacks, including hacking HBGary, Westboro Baptist Church, and Gawker. They have also claimed responsibility for the defacing of government websites in countries such as Zimbabwe, Syria, Tunisia, Ireland, Egypt and North Korea.
Rise to prominence
On February 24, 2011, Topiary gained attention after he appeared on The David Pakman Show. He informed the host that Anonymous had replaced a Westboro Baptist Church webpage with a message from Anonymous during an on-air confrontation with Shirley Phelps-Roper. A recording of this event was placed on YouTube, where it reached over one million views in five days.
On July 14, 2011, The Guardian published an exclusive interview with Topiary, in which he spoke extensively about his motivations. Describing himself as "an internet denizen with a passion for change" he said he feared being tracked by the authorities: "I can only hope that they haven't pinned any of us, especially my friends from LulzSec." Later, a full transcript of the lengthy interview surfaced on the website of freelance Guardian journalist Ryan Gallagher.
An 18-year old man suspected of being Topiary was arrested in the Shetland islands of Scotland on July 27, 2011. On July 31, 2011, the man was charged with five offences including unauthorised computer access and conspiracy to carry out a distributed denial of service attack on the Serious Organised Crime Agency's website. Scotland Yard later identified the man arrested as Jake Davis, a resident of the island of Yell. He was charged with unauthorised access of a computer under the Computer Misuse Act 1990, encouraging or assisting criminal activity under the Serious Crime Act 2007, conspiracy to launch a denial-of-service attack against the Serious Organised Crime Unit contrary to the Criminal Law Act 1977, and criminal conspiracy also under the Criminal Law Act 1977.
Police confiscated a Dell laptop and a 100-gigabyte hard drive that had 16 different virtual machines. The hard drive also contained details relating to an attack on Sony and hundreds of thousands of email addresses and passwords. A London court released Davis on bail under the conditions that he live under curfew with his mother and have no access to the Internet. His lawyer Gideon Cammerman stated that, while his client did help publicise LulzSec and Anonymous attacks, he lacked the technical skills to have been anything but a sympathiser.
Davis pled guilty on June 25, 2012 to DDoS attacks on several websites, but pled not guilty to two counts of encouraging others to commit computer offenses and fraud. Davis was due to be tried along with Ryan Cleary (Ryan), Ryan Ackroyd (Kayla), Mustafa Al-Bassam (T-Flow), beginning April 8, 2013. The court was informed it would take 3,000 hours to view the material against Ackroyd alone. They were released on bail, except for Cleary.
On April 8, 2013, Davis again appeared in court with fellow hackers, Ryan Ackroyd, Ryan Cleary and Mustafa Al-Bassam. All four plead guilty to computer crimes and were sentenced on May 14, 2013. Davis faced a maximum of 10 years in prison but got 24 months in a young offenders institute. He served 38 days because he had been Electronically tagged for 21 months and this counted against his sentence.
