While Bybit remained solvent by borrowing cryptocurrency and launched a bounty strategy to way down the stolen funds, the FBI rapidly pinned the blasted connected the North Korean hackers known arsenic TraderTraitor.

Before the Bybit heist, TraderTraitor had already been linked to different high-profile cryptocurrency thefts and compromises of proviso concatenation software.

“We were waiting for the adjacent large thing,” says Michael Barnhart, a longtime cybersecurity researcher focused connected North Korea and researcher astatine information steadfast DTEX Systems. “They didn't spell away.

Over astatine slightest the past 5 years, the totalitarian authorities of Kim Jong-un has deployed technically skilled IT workers to infiltrate companies astir the satellite and gain wages that tin beryllium sent backmost to the motherland. In immoderate cases, aft being fired, those workers extort their erstwhile employers by threatening to merchandise delicate data. At the aforesaid time, North Korean hackers, arsenic portion of the wide umbrella Lazarus Group, person stolen billions successful cryptocurrency from exchanges and companies astir the world.

TraderTraitor archetypal emerged astir the commencement of 2022, aggregate cybersecurity researchers say, and is apt an offshoot of the North Korean APT38 radical that hacked the SWIFT fiscal strategy and attempted to bargain $1 cardinal from the Central Bank of Bangladesh astatine the commencement of 2016. “They walked disconnected with precise small money,” says DTEX Systems’s Barnhart. “In that infinitesimal you had a real, important shift.”

Barnhart says North Korea realized that relying connected different people—such arsenic wealth mules—could marque their operations little effective. Instead, they could bargain cryptocurrency. Two groups emerged from that tactical shift, Barnhart says, CryptoCore and TraderTraitor. “TraderTraitor is the astir blase of all,” helium says. “And why? Because APT38 was the A team.”
