Cyber Threat / Malware
A newly identified malware, dubbed CryptoClippy, is specifically targeting Portuguese cryptocurrency users through a malvertising campaign. This sophisticated malware employs SEO poisoning techniques to lure users searching for “WhatsApp web” to malicious domains that host the threat, according to a recent report from Palo Alto Networks’ Unit 42.
CryptoClippy, written in C, is a type of cryware known as clipper malware, which monitors clipboard activity for cryptocurrency addresses. When it detects a match, the malware substitutes the copied address with one controlled by the attacker. “The clipper malware utilizes regular expressions (regexes) to ascertain the cryptocurrency type of the address,” noted researchers from Unit 42. “It then replaces the clipboard entry with a visually similar wallet address belonging to the adversary.”
