SEOUL (Reuters) - Last year was the worst on record for cryptocurrency heists, with hackers stealing as much as $3.8 billion, led by attackers linked to North Korea who netted more than ever before, a U.S.-based blockchain analytics firm said in a report on Wednesday.

The report by Chainalysis found hacking activity that "ebbed and flowed" throughout the year, with "huge spikes" in March and October. October was the biggest single month ever for cryptocurrency hacking, with $775.7 million stolen in 32 separate attacks, the report said.
