Verdict

Long-standing developer site for CrystalDisk utilities with disclosed third-party bundle

Crystalmark.info is the official home of CrystalDiskInfo, CrystalDiskMark and related utilities. The site is 8,429 days old and openly discloses that some installers bundle the E START App from GMO INSIGHT. The only commercial CTA is a voluntary PayPal donation link.

Download the standalone ZIP versions instead of the installer, or carefully uncheck the E START App option during setup. The site itself is legitimate; the only risk is the optional third-party bundle.

01 · Investigation Brief

Investigation Brief

Site legitimacy and disclosure

The domain has been registered for more than 23 years, and the page content identifies the site as the official home of the Crystal Dew World utilities authored by developer hiyohiyo.

The site explicitly warns visitors that certain installers include the E START App from GMO INSIGHT and provides a link to the partner’s terms of use.

Third-party bundle and installer risk

Security researchers have flagged the E START App installer for insecure DLL loading (JVN#68418039), which could allow local privilege escalation if an attacker places a malicious DLL in the search path.

Removal guides note that users who do not opt out during installation may receive the E START App, which some security products classify as potentially unwanted software.

Why the score is 78

Users may receive E START App if they do not opt out during install. Coverage remains separate so missing sources cannot be mistaken for clean results.

Verify before you trust

We couldn't gather enough signal for a confident verdict — tread carefully.

Find the company through independent channels
Search for the business on LinkedIn, an official registry (Companies House, OpenCorporates, SEC EDGAR), or via the brand's known social channels. If you can't trace a real entity, that itself is a red flag.
Never pay by crypto, gift card, or bank transfer
If the site forces an irreversible payment method, stop. Cards and PayPal give you chargeback protection — irreversible methods don't.

07 · Safety FAQ

Safety FAQ

Common questions, answered directly from the scan data above — so the answers reflect the saved verdict and evidence in this report.

Is crystalmark.info a scam or is it safe?

crystalmark.info has a Safety Score of 78/100 (Low Risk). The saved checks found no material threat, but the report did not meet every requirement for the highest Safe tier. Use normal caution and independently verify the operator before irreversible payments or unusually sensitive actions.

Is crystalmark.info safe to use?

crystalmark.info has a Safety Score of 78/100 (Low Risk). Analysis coverage is strong at 83%. Normal caution; verify sensitive actions.

Has crystalmark.info been flagged by antivirus engines?

No — all 92 antivirus and blocklist engines in our malware network currently report crystalmark.info 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.

Is crystalmark.info on any phishing or malware blacklists?

No — crystalmark.info 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.

How old is the crystalmark.info domain?

crystalmark.info is 23.1 years old, registered on July 24, 2003 through eNom, LLC. 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.

Does crystalmark.info have a valid SSL certificate?

Yes — crystalmark.info presents a valid TLSv1.3 certificate issued by Let's Encrypt · YR1, valid for another 69 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".

Where is crystalmark.info hosted?

crystalmark.info resolves to an IP operated by XSERVER Inc. in JP (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.

How often is the crystalmark.info report updated?

This report is a record of the scan run on August 22, 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 crystalmark.info has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
