Analysis Summary
Website Preview
Automated page render — captured in a safe sandbox. What an ordinary visitor would see when loading the site.
Visual analysis
We capture a fresh screenshot of the live page and ask a vision model to look for scam visual patterns — fake trust badges, countdown timers, overlay pop-ups, and visual clones of legitimate brands.
Visual similarities noted — cleared by the overall checks
Our vision model noted some visual similarity to a known brand, but the domain, security records, and reputation checks confirm this is the legitimate site — so this is shown for transparency, not as a red flag.

Intelligence
The domain registered in 2016 and belongs to Backblaze, Inc., a Nasdaq-listed company with active US business registration. Our antivirus network returned zero flags on the main domain and the hosting IP shows no abuse reports. The evidence package confirms this is legitimate infrastructure used for S3-compatible storage endpoints. Two scam reports reference malicious files hosted on customer subdomains such as f005.backblazeb2.com, not the root domain itself. The page is a JavaScript application that may render slowly, which explains the incomplete screenshot. These signals together indicate the domain is legitimate infrastructure rather than a scam operation.

What to do
Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on backblazeb2.com and not a lookalike like b-ackblazeb2.com.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

If you have first-hand experience with this site — good or bad — share it with the MalwareTips community.
Final Verdict
backblazeb2.com is the official infrastructure domain for Backblaze B2 Cloud Storage. The domain is 10 years old, owned by a publicly traded US company, and hosts user content that occasionally includes malicious files. Do not enter credentials on any subdomain unless you initiated the connection.
Safety FAQ
Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- Our automated security review found no threat indicators on backblazeb2.com, so it appears legitimate. All 92 antivirus engines we queried report it clean, and the domain is 10 years old, registered on July 13, 2016 — established domains are far less likely to be scams. Even so, always double-check the exact address in your browser, because phishing emails routinely spoof real, trusted domains like this one.
- backblazeb2.com passed our automated checks with a trust score of 80/100. No antivirus engines or major blacklists flagged it at the time of the last scan, and its signals line up with an established, legitimate site. Treat any unexpected login prompt or payment request on it with the same caution you would anywhere.
- Yes — and this is worth understanding. Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from backblazeb2.com), and legitimate sites are occasionally compromised on specific pages. A clean verdict means the site itself checks out today; it does not mean every email or link claiming to be from backblazeb2.com is genuine. Always reach the site by typing the address yourself rather than clicking links in unexpected messages.
- No — all 92 antivirus and blocklist engines in our malware network currently report backblazeb2.com 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 — backblazeb2.com 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.
- backblazeb2.com is 10 years old, registered on July 13, 2016 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 — backblazeb2.com presents a valid TLSv1.3 certificate issued by Let's Encrypt · YR2, valid for another 62 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".
- backblazeb2.com resolves to an IP operated by Backblaze Inc in US (Data Center/Web Hosting/Transit). 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.
- This report is a record of the scan run on July 12, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about backblazeb2.com has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
