It presents a page titled "Один момент…", Russian for "One moment…", which is the kind of wording browser-check or CAPTCHA interstitials use. PhishDestroy first saw it on 2026-10-07. As of 2026-10-19 the site was still online and serving content. No specific brand or scheme has been confirmed for it yet. How the scam works The hostname begins with "captcha" and the page title imitates a waiting screen, so the visible page is a verification step rather than any real service. Fake verification screens are a common lure in general. A visitor is told to prove they are human, then is pushed toward something harmful, such as running a pasted command, installing a file, allowing browser notifications, or moving on to a login page. Any of these can lead to stolen credentials or malware on the device. This domain's exact payload is not confirmed, so treat any instruction it gives as untrusted. Evidence Independent detection is thin. On 2026-10-19, VirusTotal showed 3 of 92 engines flagging the domain: alphaMountain.ai, Forcepoint ThreatSeeker and SOCRadar. Those three are reputation and threat-intelligence vendors, so their agreement adds some weight. Most engines have not caught up yet, though. PhishDestroy is currently the only blocklist listing it. Infrastructure The parent domain slon15.cz was registered on 2026-09-22 through REG-KEYSYSTEMS. That is only 15 days before PhishDestroy detected it, a short gap typical of throwaway domains set up for a campaign. The site is hosted on the PODAON Podaon SIA network, a Latvian operator, with the server located in the Netherlands. What to do If this page asked you to copy and paste anything into the Windows Run box, a terminal or PowerShell, disconnect the device from the network and run a full malware scan. After that, change your important passwords from a different, clean device. If you typed a username or password anywhere after the verification screen, change that password immediately and turn on two-factor authentication. Also sign out of active sessions on the affected accounts. Do not download files or allow notifications from this site. Defenders should block both captcha.slon15.cz and the parent slon15.cz. They should also check DNS and proxy logs from 2026-09-22 onward for any internal visits.
