Risk Score
PhishDestroy AI
HIGH
PhishDestroy identifies criterion-est-connections-periodic[.]trycloudflare[.]com as a high-risk brand impersonation domain targeting Rackspace users. It masquerades as a legitimate Rackspace Webmail portal, seeking to deceive users into divulging credentials by exploiting the trust associated with the Rackspace brand. This domain falls under the category of brand impersonation, designed to facilitate credential phishing.
Technical analysis reveals the domain was registered on July 7, 2018, using Cloudflare, Inc. as the registrar, and resolved to IP address 104.16.231.132, an IP space commonly associated with Cloudflare's content delivery network. Out of 95 security vendors scanning this domain on VirusTotal, 24 flagged it as malicious, and it appeared on one security blocklist, confirming consensus on its suspicious nature. The page title found, "Rackspace Webmail: Hosted Email for Business," aligns with the targeted brand, indicating an intent to trick users specifically seeking Rackspace webmail services.
Currently, criterion-est-connections-periodic[.]trycloudflare[.]com is taken offline, mitigating immediate risk of phishing attacks through this vector. Users are advised to remain vigilant against similar impersonation attempts and avoid interacting with suspicious links that claim to provide Rackspace services. Reporting phishing attempts to corporate IT teams or security bodies can further help in limiting the domain's exposure and protecting credential integrity.

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 criterion-est-connections-periodic.trycloudflare.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
criterion-est-connections-periodic.trycloudflare.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
