Intelligence
The domain bsclink.cn belongs to BaishanCloud, a legitimate Chinese CDN operator. In June 2024 the Polyfill.io service was pointed at a subdomain on this infrastructure after Funnull acquired the project. Scripts served through polyfill.io.bsclink.cn were modified to inject malicious redirects to gambling and adult sites. Security researchers documented the attack affecting more than 100,000 websites that loaded the Polyfill library. The domain itself carries no antivirus detections and shows clean hosting reputation, yet its direct role in the confirmed supply-chain compromise outweighs those clean signals. No legitimate business use explains why a CDN endpoint would serve modified malicious scripts to third-party sites.

What to do
Proceed with caution
Our automated review flagged enough risk that you should treat this site as unverified.
- Treat bsclink.cn as unverified
Do not enter credentials or send money until you have independently verified the business.
- Verify the business through independent channels
Check the company's social profiles, registry records, and search for recent news or reviews that are not hosted on the site itself.
- Never use irreversible payment methods
Crypto, gift cards, wire transfers, and cash apps offer zero buyer protection. Use a credit card or PayPal if you must pay.

Safety FAQ
Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- bsclink.cn looks like a likely scam site — avoid interacting with it. Our review tagged it for malware. 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 — bsclink.cn 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 bsclink.cn, 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 bsclink.cn 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 bsclink.cn 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 92 antivirus and blocklist engines in our malware network currently report bsclink.cn 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 — bsclink.cn 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.
- bsclink.cn resolves to an IP operated by CHINANET Guangdong province network in CN (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.
- Yes — bsclink.cn ranks in the global top 100,000 most-visited sites, which means it has substantial real-world traffic. Genuine popularity doesn't automatically make a site safe, but throwaway scam domains almost never reach this level of traffic, so it's a meaningful point in the site's favour.
- This report is a record of the scan run on July 13, 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 bsclink.cn has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
