Technical Details

The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

Contact Verification

We fetched the page and looked for real-world contact details. Legitimate businesses almost always publish an email on their own domain, a phone number, and a postal address. Scam shops usually don't.

What to do

Still, stay alert

No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.

  • Double-check the exact URL in your address bar

    Confirm you are actually on eso.bg and not a lookalike like e-so.bg.com or an IDN homoglyph.

  • Use a password manager

    Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

  • Discuss this site on the forum

    If you have first-hand experience with this site — good or bad — share it with the MalwareTips community.

Safety FAQ

Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.

  • Our automated security review found no threat indicators on eso.bg, so it appears legitimate. All 93 antivirus engines we queried report it clean, Even so, always double-check the exact address in your browser, because phishing emails routinely spoof real, trusted domains like this one.
  • eso.bg passed our automated checks with a trust score of 94/100. No antivirus engines or major blacklists flagged it at the time of the last scan, and its signals line up with an established, legitimate site. Treat any unexpected login prompt or payment request on it with the same caution you would anywhere.
  • Yes — and this is worth understanding. Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from eso.bg), and legitimate sites are occasionally compromised on specific pages. A clean verdict means the site itself checks out today; it does not mean every email or link claiming to be from eso.bg is genuine. Always reach the site by typing the address yourself rather than clicking links in unexpected messages.
  • No — all 93 antivirus and blocklist engines in our malware network currently report eso.bg as clean. That's a good sign, though antivirus coverage is only one of the many signals we weigh, and brand-new scam sites can appear clean before vendors catch up.
  • No — eso.bg is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.
  • Yes — eso.bg presents a valid TLSv1.3 certificate issued by DigiCert Inc · GeoTrust TLS RSA CA G1, valid for another 46 days. Important caveat: SSL only encrypts the connection between you and the site — it does not verify who runs it. Almost all scam sites now have valid SSL too, so a padlock alone never means "safe".
  • eso.bg resolves to an IP operated by Electroenergien Sistemen Operator EAD in BG (Commercial). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.
  • This report is a record of the scan run on July 13, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about eso.bg has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
