>"A cryptocurrency-related malware program has been advertised on darknet forums as the “leading way to make money in 2021."" "In order to “steal” cryptocurrency from a victim, Westeal uses regular expressions to look for strings matching the patterns of bitcoin and ethereum wallet identifiers being copied to the clipboard. When it matches these, it replaces the copied wallet ID in the clipboard with one supplied by the malware. The victim then pastes the substituted wallet ID for a transaction, and the funds are sent instead to the substitute wallet."
