This domain, 16421[.]xyz, is currently active and has been identified as a phishing infrastructure. DNS resolution points to the IPv4 address 103.27.177.163, hosted on nameservers a4.share-dns.com and b4.share-dns.net. VirusTotal analysis shows that 14 of 91 security vendors have flagged the domain as malicious, indicating a moderate level of detection across the scanning community. The domain is listed on one public security blocklist and has been added to the PhishDestroy blocklist, confirming its use in malicious campaigns. AlienVault OTX reports a single threat‑intel pulse referencing the domain, further corroborating its involvement in phishing activity. The registration was performed through Dynadot Inc., but no additional registration details are publicly disclosed. No specific brand or service is reported as being impersonated, and the page content has not been analyzed, leaving the exact lure unknown. Infrastructure observations suggest a low‑profile hosting configuration typical of fast‑flux or disposable services. Defenders should block both the domain 16421[.]xyz and its resolved IP address 103.27.177.163 at perimeter firewalls and DNS filters. Continuous monitoring of the associated nameservers is advised, as they may be reused for future malicious sites. Adding the domain to internal threat‑intel feeds and sharing the indicators with upstream security communities will improve collective detection. Given the active status and existing vendor detections, the risk level remains high and immediate remediation is recommended.

Domain Appeal
Contest this listing if false positive
Beware of recovery scammers! After being scammed, criminals may contact you again pretending to be "recovery agents," lawyers, or investigators who claim they can retrieve your lost funds — for a fee. This is a second scam. No legitimate service will ask for upfront payment to recover stolen crypto. Learn more about recovery fraud →

Recommendations & Advice for Victims
An estimated $51 billion flowed to illicit crypto wallets in 2024 (source). If you interacted with 16421.xyz — act now.
What should I do immediately?
Urgent
- Revoke token approvals — use revoke.cash to remove access granted to malicious smart contracts
- Move remaining funds to a brand-new wallet. The compromised wallet is no longer safe
- 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
According to the FBI, the most important details are transaction data:
- Cryptocurrency addresses — scammer's wallet (e.g.,
0x5856...35985) - Amount & crypto type — exact amount (e.g., 1.02345 ETH, 0.5 BTC, 500 USDT)
- Transaction ID (hash) — the unique blockchain transaction identifier
- 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
16421.xyz) - 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)
- Chainabuse — flag scam wallets across exchanges & platforms
- Your crypto exchange — contact Coinbase/Binance/Kraken support to freeze scammer's address
- Local police — creates an official record, even if they can't act immediately
The FBI recovered over $1 billion in crypto fraud in 2024 thanks to victim reports. Your report matters.
How do crypto scams typically work?
- Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
- Malicious approvals — "connect wallet" prompts that grant unlimited token spending to attackers
- Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
- Recovery scams — victims targeted AGAIN by fake "recovery agents" demanding upfront fees. Always a scam
- Fake ads & airdrops — Google/social media ads and "free token" offers leading to wallet drainers
- AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect
How can I protect myself in the future?
- Use a hardware wallet (Ledger, Trezor). Never store large amounts in browser wallets
- Bookmark official sites — never click links from emails, DMs, or ads
- Read every approval — verify permissions before signing. Reject unlimited approvals
- Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
- "Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines
How big is the crypto scam problem?
- $51 billion flowed to illicit crypto wallets in 2024 — CoinLedger
- Pig butchering losses grew 40% year over year, now the fastest-growing fraud type
- Only ~5% of victims report — your report helps shut down criminal networks
- FBI recovered $1B+ in 2024 thanks to victim reports — FBI.gov
