A new extortion scam is underway targeting websites owners and stating that if they do not make a payment, the attacker will ruin their site’s reputation and get them blacklisted for spam. The extortionist states that they will send millions of emails from your domain, leave nasty reviews about the recipient’s site, and submit nasty messages to other people’s contact forms pretending to be from your site. The demands then state the sender will destroy the reputation of the site if a.3 bitcoin (approximately $2,400) payment is not paid to them.
