A fake Steam skin giveaway site has been created that states it gives away news skins every day, but in reality it just steals your login credentials.
This phishing site was first discovered by researcher nullcookies where he posted a warning about it on Twitter.
After nullcookies told us that Steam phishing sites are commonly promoted directly on Steam, we performed a search and found that this scam is being promoted through comments made to Steam profiles. These comments state “Dear winner! Your SteamID is selected as a winner of Weekly giveaway. Get your Karambit | Doppler on giveavvay.com”.
