Zotob was derived from the Rbot worm. Rbot can force an infected computer to continuously restart. Its outbreak on August 16, 2005, was covered "live" on CNN television, as the network's own computers got infected. Zotob would self-replicate each time the computer rebooted, resulting in each computer having numerous copies of the file by the time it was purged. This is similar to the Blaster (Lovesan) worm.
On August 26, 2005, Farid Essebar and Atilla Ekici were arrested in Morocco and Turkey, respectively. They are believed to be the men behind the worm's coding.
A signature in the Zotob worm code suggested it was coded by Diabl0 and the IRC server it connects to is the same used in previous version of Mytob. Diabl0 is believed to have incorporated the code of a Russian nicknamed houseofdabus 11 whose journal has been shut down by authorities,12 just after the arrest of Diabl0. The coder (Ekici) probably paid Diabl0 (Essebar) to write the code.
"He says it's all about making money, and that he doesn't care if people remove the worm because it's the spyware stuff that he installs that's making him the money, Taylor said in a conversation with me."13
On August 30, 2005, controversial reports emerged from different anti-virus firms. Sophos declared that several people had access to the Mytob source code (a variant of the worm). On the other hand, F-Secure declared that it has found multiple variants of Mytob that were coded after the arrest of Essebar. Those declarations suggest that Essebar is only a part of a larger group of Dark-side hackers behind the spread of the malware.14
Farid Essebar (Arabic: فريد الصبار) (born in 1987, known as Diabl0) is a Moroccan black hat hacker. He was one of the two people behind the spread of Zotob. Essebar is also a Russian citizen.15
It is believed that his intention was to facilitate credit card forgery scams. The FBI believes that Atilla Ekici paid Essebar to code the worm. In July 2006, investigators stated that Essebar may have authored more than 20 viruses.16
On 15 September 2006 a Moroccan court sentenced Essebar to two years of prison.17 It was reduced to a year on 15 December 2006.
On 17 March 2014, Essebar was arrested in Thailand after a 2-year investigation by Thai police. The investigation was triggered by a complaint from Swiss authorities over an alleged infiltration of a Swiss bank that caused dozens of billions of dollars' damage.18
