No additional intelligence such as page title, targeted brand, or malicious payload has been published, so the exact content hosted on the site cannot be confirmed. The available evidence therefore supports a classification of generic phishing, but the specific victim or brand being spoofed is unknown. Defenders should consider adding core‑helper.com to outbound filtering rules and DNS blocklists, especially for users who may be targeted by credential‑stealing campaigns.
Continuous monitoring of the IP address 104.21.82.158 for anomalous traffic and periodic re‑scans on VirusTotal or similar platforms are recommended to capture any future changes in the domain’s behavior. Because the infrastructure relies on Cloudflare’s CDN, attribution to a single operator is difficult, and threat actors may switch front‑end services without altering the underlying domain. Until further forensic analysis of the hosted content is available, the domain should be treated as high‑risk for credential‑harvesting attempts.

Recommendations & Advice for Victims
An estimated $51 billion flowed to illicit crypto wallets in 2024 (source). If you interacted with core-helper.com — 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
core-helper.com) - 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
