December 2023 has experienced significant losses in cryptocurrency thefts, with the latest attack on Orbit Chain’s cross-chain bridge pushing the month’s total losses close to $100 million, according to blockchain security firms. Blockchain security firm PeckShield reported on Jan. 1 that the $81.5 million exploit of the Orbit Bridge was a major contributor to December being the fifth-highest month for crypto hacks in 2023. The exploit was also the ninth-highest hack targeting a cross-chain bridge over the past three years, it said.
