A newly uncovered Russian-based cybercrime operation has helped classified ads scammers steal more than $6.5 million from buyers across the US, Europe, and former Soviet states.

In a report published today, cyber-security firm Group-IB has delved into this operation, which the company has described as a Scam-as-a-Service and codenamed Classiscam.

"The ads usually offer cameras, game consoles, laptops, smartphones, and similar items for sale at deliberately low prices," Group-IB said today.

The scammer would then use a Telegram bot to generate a phishing page that mimicked the original marketplace but was hosted on a look-a-like domain. The scammer would send the link to the buyer, who would fill it with their payment details.
