CertiK: Phishing, Deepfakes, and Supply Chain Attacks Could Become the Biggest Crypto Security Threats in 2026
According to Natalie Newson, Senior Blockchain Investigator at CertiK, real-time deepfakes, phishing attacks, supply-chain compromises, and cross-chain vulnerabilities will be the primary drivers of cryptocurrency hacks in 2026. So far this year, the industry has lost over $600 million to hacking incidents—including the $293 million Kelp DAO exploit and the $280 million theft from Drift Protocol in April—both linked to a North Korean hacker group.
Newson warns that the accelerated advancement of AI will make attack methods increasingly sophisticated, including more realistic deepfakes, autonomous attack agents, and “agent AIs” capable of automatically scanning smart contracts for vulnerabilities. However, AI can also serve as a defensive tool. CertiK advises investors to verify URL authenticity and store assets in cold wallets to mitigate risk.
