A new campaign is evading secure email gateways that rely on identifying word patterns in order to filter out spam.

Sextortionists typically gather target emails from prior credential breaches; and the scam messages sometimes offer, as proof of compromise, a password associated with the victim s online accounts. Researchers at Symantec analyzed data from the 5,000 most-seen Bitcoin addresses in May and found that 63 of those wallets received 12.8 bitcoins through 243 transactions in a month.
