PhishDestroy threat report

Overview

captcha.slon15.cz is a subdomain on the PhishDestroy blocklist. 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.

Questions about captcha.slon15.cz

Is captcha.slon15.cz legit?

No. PhishDestroy classifies captcha.slon15.cz as a blocklisted domain (risk: critical, 76/100); it was first detected on 2026-10-07. VirusTotal: 3/92 engines flag it. Treat the site as unsafe.

Is captcha.slon15.cz safe to connect a wallet?

No. Do not connect a wallet, sign messages or approve tokens on captcha.slon15.cz. Phishing sites ask for approvals (approve, setApprovalForAll, Permit2) that let the operator move your assets, and a confirmed transaction cannot be reversed.

What should I do if I used captcha.slon15.cz?

Change every password you entered there and turn on two-factor authentication. If you connected a wallet or signed something, revoke the approvals and move the remaining funds to a new wallet; never share your seed phrase. Step-by-step help: emergency guide.

After a phishing incident

Recommendations & Advice for Victims

Choose the steps that match what you shared. Keep a copy of this report alongside your own records.

What should I do immediately?

Urgent

Stop using the suspicious site. Open the real service through its official app or an address you already trust.

  • Change all passwords — email, exchange accounts, anything that shares the same password
  • Enable 2FA using an authenticator app (not SMS). Disable SMS-based recovery
  • Freeze cards if you entered banking details on the phishing site

What information should I collect for my report?

FBI guidelines

Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗

  • Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
  • Exact dates & times — of each transaction and first contact with scammer
  • Screenshots — scam website, chat messages, emails, wallet transactions, social media
  • All URLs & domains used by the scammer (including captcha.slon15.cz)
  • Communications — emails, texts, phone numbers, usernames the scammer used

Even if you don't have all details — file a report anyway. Partial information still helps investigations.

Where should I report the scam?

  • FBI IC3 — Internet Crime Complaint Center (US federal reporting)
  • Europol — European cybercrime reporting (EU)
  • Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
  • Local police — creates an official record, even if they can't act immediately

A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.

How do phishing scams typically work?

  • Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
  • Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
  • Recovery scams — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
  • AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect

How can I protect myself in the future?

  • Bookmark official sites — never click links from emails, DMs, or ads
  • Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
  • "Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines

This report combines saved page captures, registration and network records, scanner results and PhishDestroy reporting history. Each source keeps its own observation date. Open a source report to inspect the original result.

The AI-assisted analysis was written on . It describes the evidence available at that time; later source checks can change.

A capture documents what was shown. A scanner result records that provider’s assessment at the time of its check. Neither a valid certificate nor a zero-detection result is a guarantee of safety.
