North Korean cybercriminals have executed a strategic pivot in their social engineering campaigns, stealing more than $300 million by impersonating trusted industry figures in fake video meetings on platforms like Zoom and Microsoft Teams. This warning comes from MetaMask security researcher Isabella Rossi, who outlines a sophisticated "long-con" specifically targeting crypto executives.
The new attack vector weaponizes professional courtesy. Hackers exploit the formal setting of a business meeting to bypass skepticism and trigger urgent action from their targets.

"This specific vector weaponizes professional courtesy. The hackers rely on the psychological pressure of a 'business meeting' to force a lapse in judgment, turning a routine troubleshooting request into a fatal security breach."
The Scale of the DPRK Threat
Note: The $2B+ figure includes other major attacks like the Bybit breach. The fake meeting campaign is notable for its low-tech, high-trust approach.
The Attack Chain: From Hijacked Telegram to Remote Access Trojan
According to Isabella Rossi, this campaign departs from recent attacks that relied on AI deepfakes. Instead, it uses a more straightforward yet effective approach built on hijacked Telegram accounts and looped footage from real interviews or podcasts.
The multi-stage attack is carefully orchestrated to build trust and create a sense of urgency:
| Stage | Tactic | Objective |
|---|---|---|
| 1. Infiltration | Hijack a trusted Telegram account (e.g., a VC or conference contact). | Gain a credible identity and access to prior chat history. |
| 2. Lure | Contact the victim using the trusted account, suggesting a video call via a disguised Calendly link. | Move the interaction to a video platform where visual trust is established. |
| 3. Deception | Use pre-recorded video (from a public appearance) instead of a live feed. | Present a believable presence without the risk of live interaction. |
| 4. Trigger | Stage a "technical issue" (audio/video problems). | Create a pretext for requesting action from the victim. |
| 5. Payload | Urge the victim to download a "fix" (script/SDK update) to restore the call. | Deliver the malicious Remote Access Trojan (RAT). |
| 6. Exfiltration | The installed malware drains wallets and steals data (including Telegram sessions). | Complete the theft and gather tokens to target the next victim. |
The decisive moment is the manufactured technical issue. By creating a minor problem that needs to be "solved together," the attacker transforms from a conversational partner into someone requiring assistance, flipping the dynamic and making the victim more likely to comply with a download request.
The Psychology: Why This "Low-Tech" Approach Works
This attack is effective precisely because it avoids cutting-edge technology like real-time deepfakes, which can raise suspicion. It leverages several powerful psychological principles:
- Trust Transference: The attacker inherits the trust established by the legitimate account owner.
- Contextual Authority: The formal setting of a scheduled business meeting lowers guards compared to a random message.
- Social Pressure & Urgency: The need to "fix the call" creates time pressure and a desire to be helpful, short-circuiting careful analysis.
- Plausible Deniability for Glitches: Slight video lag or low quality in a call is normal, making the recycled footage believable.
The Critical Red Flag
For industry participants, any request to download software or run a script during a live call should now be treated as an active attack signal.
This is the universal takeaway from security researchers. No legitimate contact will ever ask you to install or execute something to fix a simple connection issue on a standard conferencing platform.
Broader Context & Defensive Recommendations
This "fake meeting" strategy is part of a broader offensive by Democratic People's Republic of Korea (DPRK) actors, who have stolen an estimated $2 billion from the crypto sector over the past year, including through other major breaches like the one targeting Bybit.
Immediate defensive actions for teams and individuals include:
- Verify Out-of-Band: If a contact suggests a call, confirm via a separate, previously established communication channel (e.g., a verified email or a different messaging app).
- Question Urgent Fixes: Be deeply skeptical of any request to download files, update software, or run scripts during a call.
- Use Meeting Codes Directly: Manually enter meeting IDs from official sources instead of clicking links, even from trusted contacts.
- Segment Communications: Do not use the same messaging app for sensitive operational discussions and for scheduling initial calls with new contacts.
FAQ: The $300M Zoom Meeting Hack
Are the hackers using AI deepfakes?
No. According to the analysis, the attackers are using a more straightforward method: recycled video footage from actual public interviews or podcast appearances of the person they are impersonating. This makes the deception harder to detect in real-time, as viewers attribute minor glitches to normal connection issues.
What is the #1 red flag to look for?
The single biggest red flag is a request to download software or run a script to "fix" the video call. No legitimate conferencing platform (Zoom, Teams, etc.) requires users to download external fixes from a participant. This action should immediately terminate the call and trigger a security investigation.
If I clicked a link but didn't download anything, am I safe?
Not necessarily. While the primary payload is a download, simply clicking a malicious Calendly or meeting link could expose your IP address, device information, or other data. You should run a full malware scan and monitor your accounts for any suspicious activity. Consider the device potentially compromised.
Conclusion: The North Korean hacking campaign represents a sophisticated evolution in social engineering, trading technological complexity for psychological manipulation. By exploiting professional norms and the inherent trust in video communication, attackers have found a highly effective vector. The crypto industry's defense must now extend beyond verifying code to verifying human interactions. The fundamental rule is simple: if a fix for a business call requires a download, it is an attack.
