Your site was flagged by 0xSI_f33d. Our experts will get it removed.
About the vendor
0xSI_f33d is a community-driven threat intelligence feed operated by SK-CERT (Slovak National CERT) and its partners. It aggregates malicious URLs, IP addresses, and domain indicators from Slovak internet monitoring, honeypot networks, and European security-sharing consortiums. Security vendors and ISPs across Europe pull from this feed to populate their blocklists automatically.
A listing in 0xSI_f33d can propagate within 24 hours to dozens of downstream European security products, enterprise firewalls, and DNS filtering services — silently blocking your users without any warning.
Common causes
Complete removal guide
Follow these steps to submit a false positive report yourself. This is a complete, expert-level walkthrough of the 0xSI_f33d delisting process.
Scan your domain on VirusTotal.com and check whether 0xSI_f33d specifically shows a detection. Note the exact classification label (phishing, malware, suspicious, etc.) — this determines which submission path to use and how to frame your evidence.
Before claiming a false positive, verify your site is genuinely clean. Check for injected scripts, compromised plugins, hidden iframes, unauthorized redirects, malicious file uploads, and outbound links to flagged domains. If your site was genuinely compromised, clean it before reporting to 0xSI_f33d.
Check your source code, server access logs, CMS plugin list, and all third-party scripts. A single overlooked compromise will cause your dispute to be denied.
Collect clean scan results from other major security vendors (Google Safe Browsing, VirusTotal aggregate), screenshots of your legitimate content, your business registration details, domain WHOIS history, and documentation of any recent security hardening measures.
Visit 0xSI_f33d's official false positive or dispute submission portal. Provide your domain URL, explain your business purpose, describe why the flag is incorrect, and attach your clean evidence. Use a professional email address matching your domain for implicit ownership verification.
Response times vary by vendor. 0xSI_f33d typically responds within the stated timeframe if your submission is complete and well-documented.
Save any ticket or reference numbers provided. If you haven't received a response within the stated timeframe, follow up politely referencing your original submission. Re-check VirusTotal after receiving confirmation to verify the flag is cleared.
After confirmation, re-scan your domain on VirusTotal to verify 0xSI_f33d's detection is cleared. Set up ongoing monitoring to catch any future flags early — recurrence within 30 days is common if the underlying trigger isn't fully addressed.
Once 0xSI_f33d confirms removal, the update propagates to all their products and any downstream consumers of their threat data. Propagation typically takes 24-48 hours for full global coverage. VirusTotal results update on the next rescan.
