Bomb Threat Hoaxer, DDos Boss Gets 3 Years
The ringleader of a gang of cyber hooligans that made bomb threats against hundreds of schools and launched distributed denial-of-service (DDoS) attacks against Web sites — including KrebsOnSecurity on multiple occasions — has been sentenced to three years in a U.K. prison, and faces the possibility of additional charges from U.S.-based law enforcement officials.
George Duke-Cohan, 19, caused a massive uproar earlier this year after communicating a series of bomb threats against 1,700 schools, colleges and universities across the United Kingdom. But shortly after being arrested on suspicion of the threats and released, Duke-Cohan was back at it again — this time expanding his threats to include schools in the United States.
One of many tweets from the attention-starved Apophis Squad, which launched multiple DDoS attacks against KrebsOnsecurity over the past few months.
At the same time, authorities in the U.K. and U.S. discovered that Duke-Cohan was responsible for falsely reporting the hijack of a plane bound for the United States. That flight, which had almost 300 passengers on board, was later quarantined in San Francisco pending a full security check.
Duke-Cohan was part of an attention-seeking group of ne’er-do-wells who called themselves the Apophis Squad. Duke-Cohan and his crew modeled themselves after the actions of the Lizard Squad, another group of e-fame seeking online hoodlums who also ran a DDoS-for-hire service, called in bomb threats to airlines, DDoSed this Web site repeatedly and whose members were nearly all subsequently arrested and charged with various cybercrimes.
Indeed, until recently the Apophis Squad’s Web site and DDoS-for-hire service was hosted on the same Internet server used by a handful of other domains that were tied to the Lizard Squad.
Earlier this year, KrebsOnSecurity.com came under sustained attack from the Apophis Squad, who took to Twitter to taunt this author while the attacks were underway. Duke-Cohan and other Apophis Squad members also attacked the free email service Protonmail, even as all of them continued to use their Protonmail accounts to communicate about the attacks.
KrebsOnSecurity assisted Protonmail in its investigation into the attacks, and the company later credited this author with helping to identify Duke-Cohan as the driving force behind the DDoS attacks.
Sources close to the investigation say Duke-Cohan may yet see additional charges from U.S.-based authorities. Also, several other members identified by this author as alleged co-conspirators along with Duke-Cohan have not yet been charged with a crime either in the U.K. or in the United States.
It’s not always fun when your site isn’t responsive because of determined attacks from groups like the Apophis Squad, but I try not to get too bent out of shape when these attacks do occur — mainly for two reasons: Firstly, those responsible typically end up getting busted and going to jail. Also, I usually get at least one good story out of it. In this case, make that two good stories.
