Chainalysis reports 420% rise in state-linked on-chain malware

Chainalysis has reported a 420% surge in on-chain malware, attributing the increase to state-linked hacking groups. The blockchain analytics firm said the activity involved North Korea-linked actors and suspected Iran-linked actors.

North Korea-linked hackers used Tron, Aptos and BNB Chain to maintain malware infrastructure, according to Chainalysis. Suspected Iran-linked actors embedded directions in Bitcoin transactions, the firm said.

The finding points to the use of public blockchain networks as operational infrastructure, rather than only as payment or investment rails. It also indicates that different chains are being used in different ways by the groups identified in the research.
