Victim complaints reveal losses of over $200,000 for one impersonated company, and besides this, the researchers uncovered:-

1000 impersonated organizations

6000 fake domains spanning 12 Autonomous Systems

With losses averaging $100,000 per impersonated company and numerous victims, the scam’s potential collective impact could exceed $100 million, affecting over 100,000 people, highlighting its substantial threat.

Webwyrm scammers target victims on social media, especially WhatsApp, possibly focusing on job seekers by referencing recruitment portals. 

They lure victims with fake job offers, requiring cryptocurrency deposits on platforms like KUCOIN or SHAKEPAY for supposed security or returns.

Victims, once onboard, create organization-related accounts and receive 100 USDT. They perform combo tasks initially, earning well, but later get stuck in a loop, depleting their bank accounts in hopeless attempts to complete tasks.

After getting in touch with the referrer or developers, they demand that the victims complete their daily responsibilities or threaten to freeze their accounts while providing a 24-hour money extension. 

When victims are shut out, they join a discussion where others brag about their successes in order to support the authenticity of the scam.
