Unmasking the GrassCall campaign: the hackers behind job recruitment cyber scams

Thursday 25 September 09:00 - 09:30, Green room

Dixit Panchal & Soumen Burma (Quick Heal Technologies)

The "GrassCall" campaign exploits the job recruitment process to execute cyber scams, primarily targeting individuals in the cryptocurrency and Web3 sectors. Orchestrated by the Russian-speaking threat actor "Crazy Evil", this campaign leverages a combination of social engineering, malicious software, and advanced information-stealing tactics to compromise victims' systems and access sensitive data.

We have analysed the campaign in detail. The operation begins with the creation of fraudulent companies, complete with authentic-looking websites and active profiles on professional platforms like LinkedIn. These entities post high-quality job listings to lure candidates. Once victims engage, communication transitions to encrypted messaging platforms like Telegram, where candidates are directed to download a custom video-conferencing application named "GrassCall" from malicious domains (e.g. "grasscall[.]net").

We will present full details of our analysis.
