What did CZ warn about North Korean hackers targeting crypto firms?

Former Binance CEO Changpeng Zhao (CZ) warned that North Korean hackers are intensifying targeted attacks on cryptocurrency companies, focusing on software development, security and finance roles to gain insider access. He emphasized social engineering, fake customer-support approaches and bribery as key attack vectors.

How are threat actors gaining access to cryptocurrency companies?

Threat actors from the Democratic People’s Republic of Korea commonly use recruitment and infiltration tactics to place operatives in critical roles. They also pose as customers or employers in phishing and customer-support scams. These methods let attackers obtain credentials, private keys or privileged system access, increasing risk to corporate reserves and user funds.

$2.2 billion worth of stolen crypto: How large is the 2025 theft wave?

Industry data compiled by blockchain analytics firms indicates ~ $2.2 billion in crypto was stolen from cryptocurrency companies in 2025, with a single high-profile exploit — the $1.5 billion Bybit incident — representing a major portion. The U.S. Treasury added a DPRK-linked cyber group to its sanctions list in July 2025 for related cyber espionage activity.

What do forensic and analytics reports show?

Blockchain analytics firms and public enforcement notices report a concentration of thefts tied to state-sponsored or state-aligned cybercrime groups. Key findings include: short-lived laundering chains, use of decentralized mixers (where applicable), targeted wallet compromises and repeated exploitation of misconfigured services. Analysts recommend prioritized hardening of developer and security workflows.

How should companies and regulators respond?

Companies must treat recruitment and support channels as security perimeters. Adopt strict background checks, segmented access controls, continuous code reviews, and privileged-access monitoring. Regulators should coordinate threat intelligence sharing and enforce minimum cybersecurity standards for custodial and non-custodial providers.
