Is krnlios.com legit or a scam?
Malicious clone of krnl.cat impersonating Roblox executor; confirmed fake by Reddit community with warnings of malware risk.
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.

MT Intelligence
This domain is a deliberate clone of krnl.cat, a known Roblox script executor. The site mimics the legitimate brand's name ('krnlios' vs 'krnl'), copies its page layout and claims, and falsely presents itself as the official source for iOS script execution. Reddit users in the Roblox exploiting community explicitly identify this domain and similar fakes as malware vectors, stating only krnl.cat is legitimate. The WHOIS owner is hidden behind a privacy service, no business registration exists, and independent trust aggregators assign it a score of 0 due to hidden ownership and in-game currency/exploit content. The site's own page ironically warns users about fake websites while being one itself — a classic social-engineering tactic. Our scam-network fingerprint confirms this is a typosquat and clone of the original.
