Score breakdown
See the live page ↓These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

Intelligence
The URL follows the precise pub- followed by 32 hexadecimal characters pattern that multiple security vendors have documented as a common phishing hosting method. Three separate threat intelligence reports describe attackers using these exact R2 subdomains to host fake login pages targeting Microsoft and Outlook accounts. The page currently returns a 404, which is typical when the attacker removes the phishing content after a campaign ends or when the bucket is taken down. The domain itself is 3.9 years old and belongs to Cloudflare's legitimate object storage service, yet the specific subdomain naming convention is the red flag. No business registration exists because this is not a business site but rather a storage bucket that threat actors can spin up instantly. The combination of the documented abuse pattern and the hosting infrastructure explains the high scam likelihood despite the clean current scan.
Web Research Findings
Our live research agent queries scam-report databases, consumer-review sites, news coverage, and general web search for pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev, then cross-checks business-registration records and look-alike domain patterns. Everything below is pulled from what it actually found.
- The domain 'pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev' is a public Cloudflare R2 object storage bucket.
- Cloudflare R2 subdomains following the 'pub-[32-character-hex-string].r2.dev' pattern are widely documented as being abused by threat actors to host phishing pages and malware.
- Security researchers have identified these R2 buckets as common hosts for credential-harvesting pages targeting Microsoft, Outlook, and other services.
- The infrastructure is often used to bypass security filters because it leverages a legitimate, trusted service (Cloudflare).
- Security vendors, including Malwarebytes, have historically blocked various subdomains under the r2.dev domain due to their association with phishing and riskware.
- LevelBlueopen
"For the past 60 days, we saw more than 2,000 phishing emails containing phishing URL links abusing r2.dev service... The common URL structure is https://pub-{32 Hexadecimal String}.r2.dev/."
- Netskopeopen
"Users can spot similar phishing pages hosted on R2 by inspecting the URL for the pattern pub-*.r2.dev."
- Keep Awareopen
"The R2 subdomains abused for malicious purposes have been observed and reported as most commonly beginning with “pub-”, followed by a hexadecimal string (primarily 32 characters long)."
LevelBlue reported over 2,000 phishing emails in 60 days using r2.dev URLs with the pub-[hex] structure. Netskope published guidance on identifying these R2-hosted phishing pages by the subdomain pattern. Keep Aware confirmed the same naming convention is widely abused for credential harvesting. No positive reviews or business registrations were found, consistent with a storage bucket rather than a commercial site.

Final Verdict
This is a Cloudflare R2 storage bucket URL following the exact pattern security researchers have linked to phishing campaigns. The page itself shows a 404 error, but the subdomain structure matches thousands of documented credential-harvesting links.
Safety FAQ
Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev raises serious red flags as a scam site — avoid interacting with it. Our review tagged it for phishing. The domain is 3.9 years old through CloudFlare, Inc.. It may not be an outright scam, but the risk is high enough that you should verify it independently before trusting it with money or data.
- Proceed with caution — pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev scores 46/100 on our trust scale. We found enough warning signals to recommend verifying it through independent channels before entering credentials or money.
- If you've already paid or handed over details on pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev, act quickly. 1) Contact your bank or card issuer immediately and ask to dispute the charge or open a chargeback — the sooner you act, the better your odds. 2) Report the site to the U.S. FTC at reportfraud.ftc.gov or the FBI's IC3 at ic3.gov, and in the UK to Action Fraud at actionfraud.police.uk. 3) If you entered a password, change it on pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev and anywhere you reused it, and turn on two-factor authentication. 4) Watch your bank and email for follow-up fraud, and keep screenshots as evidence.
- Often yes, if you act fast. Payments made by credit or debit card can frequently be reversed through a chargeback or dispute — contact your bank right away and explain it was a fraudulent site. Bank transfers and gift-card or voucher payments are much harder to recover, but you should still report them to your bank and to the FTC (reportfraud.ftc.gov) or Action Fraud (actionfraud.police.uk). Avoid any "refund" or "recovery" service that contacts you first — it's usually a follow-up scam.
- Just viewing a scam page is usually low-risk on an up-to-date browser — the real danger is what it asks you to DO (enter details, download a file, send money). If you downloaded anything, run a full antivirus scan and treat the file as untrusted. If you entered a password or card number, change the password everywhere you reused it and contact your bank.
- You can report pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev through several official channels: the U.S. FTC at reportfraud.ftc.gov, the FBI's Internet Crime Complaint Center (IC3) at ic3.gov, and — in the UK — Action Fraud at actionfraud.police.uk. You can also flag it to Google Safe Browsing (safebrowsing.google.com/safebrowsing/report_phish) so other browsers warn about it, and report it to the company being impersonated if there is one. Reporting helps get scam sites taken down faster.
- Modern scams are built to look convincing. A valid SSL padlock, a polished template, stock photos, fake reviews, and a trust badge can all be added in minutes and prove nothing about who runs the site. Scammers buy cheap domains, clone real designs, and copy legal pages wholesale. That's exactly why an automated review that checks the domain's age, hosting, blacklists, and behaviour — rather than just how the page looks — is more reliable than a first impression.
- No — all 0 antivirus and blocklist engines in our malware network currently report pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev 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 — pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev 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.
- pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev is 3.9 years old, registered on August 23, 2022 through CloudFlare, Inc.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.
- Yes — pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev presents a valid TLSv1.3 certificate issued by Let's Encrypt · YE1, valid for another 85 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".
- pub-b0c8d82c3e244a2fbf1133bf122e76fa.r2.dev resolves to an IP operated by Cloudflare, Inc. in US (Content Delivery Network). 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.
