If you’re not a gamer you may be unfamiliar with “skins.” A skin is a different look for a player’s character: mostly clothing, but also other aspects of the character’s appearance.
The site doesn’t actually give any skins away, and examining the source code of the site reveals that the chat messages are being generated by a JavaScript script. The site has already been flagged by Cloudflare as a suspected phishing site, but the attacker can easily move the scam to a different domain. Most Steam phishing schemes, including this one, are spread via comments on Steam itself, so users should beware of links offering free content. New-school security awareness training can help your employees recognize a scam when they see one.
