sylquorin79.pro hosted a credential phishing page titled "System Login", a deliberately generic sign-in screen that names no company or service. It targeted anyone sent there through a link, email or message who believed they were logging into a legitimate account. PhishDestroy first flagged it on 2026-09-26. The site went offline on 2026-10-19 and was still dead when last checked that day.
How the scam works
The page presented a plain login form under the heading "System Login". Bland portal labels like this suit lures that claim an account needs verification or a session has expired, because the victim fills in whatever credentials the lure suggests. Every username and password typed into the form went straight to the operators, who can then sign in to the real account, reuse the password on other services, or sell the stolen logins.
Evidence
On 2026-10-07, VirusTotal showed 15 of 92 security engines flagging the domain. The vendors included alphaMountain.ai, BitDefender, CRDF, CyRadar, ESET, Forcepoint ThreatSeeker, Fortinet and G-Data. That is a meaningful minority from well-known vendors. Spamhaus lists the domain in its DBL under the spam category, which fits a domain promoted through bulk messaging. It also appears in one AlienVault OTX pulse and on the PhishDestroy blocklist.
Infrastructure
The domain was registered through TuringSign Inc. d/b/a Cosmotown on 2026-09-15, eleven days before PhishDestroy detected it. That short gap is typical of throwaway phishing domains. The random-looking name with a numeric suffix and a .pro extension points the same way. The site ran on 45.231.49.148 in the ABGON COMUNICACIONES network in Chile. It used a free Let's Encrypt certificate, so the browser padlock said nothing about whether the page was trustworthy.
What to do
If you entered a username and password on this page, change that password immediately. Also change it on every other service where you reused it, starting with email, since email controls password resets. Turn on two-factor authentication, preferably an authenticator app or hardware key, and review recent sign-ins and active sessions for anything unfamiliar. If the credentials belonged to a work account, tell your IT or security team right away so they can reset access and check logs. Defenders should block the domain and its IP, search mail and proxy logs for traffic to it between 2026-09-15 and 2026-10-19, and treat any account that logged in from those clicks as potentially compromised.
