AI Empowered Cybercriminals: Over Two-Thirds of Banned Accounts Utilized Intelligent Tactics for Attacks

In a shocking revelation, AI firm Anthropic has disclosed that 67% of the accounts banned for policy violations over the past year had used artificial intelligence to facilitate cyberattacks, a trend that underscores the evolving sophistication of online threats. Following an examination of 832 banned accounts between March 2025 and March 2026, Anthropic reported that 560 of these accounts employed AI to develop malware and execute various malicious tactics.
This data not only highlights a troubling rise in AI-assisted cybercrime but also correlates with a staggering spike in cryptocurrency theft, with hackers pilfering $629.7 million in April—the highest amount since February 2025. Analysts argue that the growing utilization of AI technologies among malicious entities is a driving factor behind this alarming trend.
Rising Threat Levels
Manuel Aráoz, founder of the crypto security platform OpenZeppelin, expressed significant concerns on May 27, declaring, “all of DeFi [decentralized finance] unsafe” as AI models increasingly exploit weaknesses in smart contracts. While the majority of AI applications in these attacks are centered around pre-attack preparations, Anthropic reported that 6.5% of the banned accounts were harnessed for “lateral movement”—a euphemism for advanced techniques employed by hackers after initial system access.
“Previously, these advanced post-compromise techniques were limited to highly skilled individuals,” Anthropic noted. “Now, AI is enabling less experienced criminals to perform complex operations that could significantly jeopardize security protocols.”
Escalation of AI Threats
Worryingly, the risk classification of compromised accounts has seen an uptick; a third were categorized as “medium risk or higher” in the initial six months of the study, but this figure surged to 56% in the latter half. Recent research conducted by Google underpins the gravity of these threats, reporting what may be the first instance of AI used to engineer a zero-day exploit that compromised two-factor authentication systems—demonstrating a concerning leap in hacker capabilities.
In one notable incident in November, a state-sponsored group from China executed a breach where an AI model operated with remarkable autonomy, engaging in exploit activities, credential theft, and critical decision-making, all while a human actor intervened at pivotal moments. “These are exactly the kinds of behaviors we expect to see as AI technologies continue to advance,” Anthropic cautioned.
Looking Ahead
As cyber vulnerabilities become increasingly pronounced, Anthropic is preparing to launch its advanced AI model, Mythos, which has already flagged over 10,000 significant security weaknesses in widely-used software. With the threat of AI-powered hacking looming larger, the urgency for organizations to fortify their cybersecurity measures has never been more critical.
