Scam websites are advertising free Bitcoin scam. This scam is found by independent security research that has named it as Frost on Twitter. Free Bitcoin worth of $5-30 per day is offered by running the so-called Bitcoin Collector program but once it is clicked, it will only install ransomware or password-stealing Trojans to the victim’s device. According to the reports, the latter version is more dangerous as the Trojan contained inside can steal login credentials of visited sites, retrieve browser history, steal cryptocurrency wallets, etc.
