Binance CSO Jimmy Su: North Korean Hackers Use Crypto Job Deepfakes
Binance CSO warns North Korean hackers are using fake resumes, voice changers, and open-source code attacks to breach crypto firms.

- North Korean hackers pose as job seekers using deepfakes
- Open-source code poisoning is a growing attack vector
- Binance CSO warns they are the biggest crypto threat today
Binance’s Chief Security Officer, Jimmy Su, has raised serious concerns about a disturbing trend in the crypto space: the increasing sophistication of North Korean hackers. These attackers have become the biggest threat to the industry, and they’re not just relying on traditional methods. Instead, they’re going undercover—disguising themselves as job seekers and even using deepfakes and voice changers during interviews.
According to Su, these hackers apply for roles at major crypto companies daily. Their goal? To get inside the system. By pretending to be skilled developers or analysts, they try to infiltrate organizations from within. Some of them use advanced technology like synthetic videos (deepfakes) and voice modification tools to make their deception more convincing during remote interviews.
Poisoning the Code and Faking the Offers
But their tactics go beyond fake job interviews. Su also revealed that these threat actors poison open-source code repositories—like those on NPM (Node Package Manager)—which are widely used by developers across the crypto ecosystem. Once this malicious code gets unknowingly integrated into company tools, it creates a backdoor for hackers to exploit.
Another alarming strategy involves posing as high-paying recruiters. These fake recruiters lure talent from legitimate firms, potentially stealing sensitive information during the process. The combination of social engineering, tech manipulation, and software sabotage makes this a dangerous new era for crypto cybersecurity.
What This Means for the Crypto Industry
The rise of North Korean hackers in crypto is a wake-up call. It’s no longer just about protecting wallets or securing blockchains. Crypto companies now need to be extra cautious with their hiring practices, developer tools, and recruiter interactions.
Security teams are urged to conduct thorough background checks and use AI detection tools to spot deepfakes and voice changers. As these tactics become more widespread, awareness and vigilance will be the crypto world’s best defense.
