Around 72,000 devices in 2019 alone were infected during a malware campaign to steal cryptocurrency, according to the research report published by cyberintelligence company Prevailion on Oct. 2.
The Trojan malware, called MasterMana Botnet, uses cheap Russian malware which is delivered a via a phishing mailing. The malware itself likely costs just $160, including the cost of a virtual public server.
Prevailion warned, despite the cheapness of MasterMana Botnet, the scammers reached 2,000 devices each week since December 2018.
“We suspect that this particular threat actor is likely to continue operations, as previous public reporting has not deterred them, therefore we wanted to highlight their new modus operandi, so that network defenders may more easily identify their operations,” the report says.
The increase in the cost of cryptocurrencies has led to new threats being revealed on a weekly basis. Last week, cybersecurity experts warned crypto holders on a new spyware which uses Telegram messenger to swap user wallet addresses with its own.
