Michael Saylor Warns of AI-Powered Attacks After Binance Theft

Approximately $6.3 billion was stolen from Binance last week by hackers. Michael Saylor has cautioned that AI-equipped attackers will target the most vulnerable software that stores customer funds.

Anyone storing coins on an exchange faces that risk. Binance claims to have replenished the majority of the stolen funds from its reserves, but the breach originated from a classic ploy — a fake job interview.

Saylor Says Exchange Software, Not Bitcoin, Is What Attackers Aim For

Saylor chairs MicroStrategy, a firm whose primary holding is Bitcoin (BTC). During the OranjeBTC Summit in São Paulo, he fielded questions about Binance and a separate incident in Brazil.

Security company Hypernative flagged over $40 million in suspicious transfers from Brazilian exchange Mercado Bitcoin on November 2.

According to Saylor, frontier AI models — the most advanced systems from labs such as Anthropic and OpenAI — greatly enhance hacker capabilities.

“The real threat is someone, a very focused AI hacker, aimed at new software not properly tested, not locked down, that someone rushed into production too quickly.”

He called on exchanges, banks and custodians to test those models daily against their own systems.

“Bitcoin’s sound. Rickety, poorly constructed digital commerce software is going to be hacked.”

He further noted that each new feature on Ethereum, Solana or Cardano provides another entry point for attackers.

Was AI Involved in the Binance Hack?

Binance reports that a fake recruiter tricked an engineer into downloading a bogus job "assignment."

The attackers subsequently used Binance's own internal AI tool to compromise other employee accounts. However, Fortune reported that the attack primarily relied on standard phishing techniques.

The FBI attributed the attack to North Korea. TRM Labs linked it to TraderTraitor, the same group the FBI held responsible for the $1.5 billion Bybit breach in 2025.

Tether and Circle froze the stolen stablecoins, which are tokens pegged to the US dollar.

Binance now intends to broaden its AI-powered threat detection. In the meantime, India's cyber agency warned on November 4 about an AI-assisted hacker group that is stealing wallet keys from cryptocurrency exchanges.

The next milestone is Binance's updated proof of reserves — a public verification that it still custodies customers' coins — which is expected after repairs are completed.
