Description of amsi.fail
amsi.fail appears to be a niche cybersecurity tool website focused on Microsoft Windows AMSI, the Antimalware Scan Interface. Based on the page title, metadata, and visible interface, the site provides a generator for obfuscated PowerShell snippets intended to break or disable AMSI within the current process, along with explanatory material and links to related research and code repositories.
The site appears to be operated as a technical project rather than a commercial service. Its homepage references developer-oriented resources such as code hosting profiles, security research articles, and social posts from known infosec sources, which suggests the audience is likely security researchers, red-team practitioners, penetration testers, or advanced administrators studying AMSI behavior and bypass techniques.
Although the content appears educational or tooling-oriented, the subject matter is dual-use. Tools that disable or evade security controls may be used in legitimate testing environments, but they may also be misused outside authorized contexts.
Safety Assessment for amsi.fail
At the time of this scan, no detections were reported by 0 out of 91 security engines, and the domain was not listed by the checked content-malice and phishing blacklist databases. The domain is also several years old, which can be a stabilizing signal when considered alongside clean multi-engine and blacklist results.
One malware scanner did label the page and several related resources as suspicious, and it also flagged a linked research article and referenced domain with a generic suspicious classification. Based on the available details, this appears to be a low-confidence heuristic result tied to the site's AMSI-bypass content rather than broad consensus from multiple security engines. Because the website explicitly offers PowerShell code intended to disable or evade an antimalware interface, some scanners may treat the content as potentially risky or offensive-security related even when no direct malware payload is detected.
In practical terms, the main concern here appears to be the nature of the content rather than evidence of active phishing, malware hosting, or blacklist activity. Visitors should still use caution, especially in managed enterprise environments, because generated bypass code may violate policy or trigger endpoint defenses. Based on available scan data, no significant threats were detected at the time of this scan.
Technical Description
The domain uses a valid SSL/TLS certificate issued by a mainstream certificate authority, with expiry shown as 2026-11-24. It is hosted behind Cloudflare infrastructure on IP address 104.21.43.86, with Cloudflare nameservers and a web server response identified as Cloudflare. The domain has been registered for about six years and is currently set to expire in 2027.
DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from that additional integrity layer. No major infrastructure-level warning signs were provided in the scan data, and the blacklist checks were clean at the time of review. The primary technical caution is content-related: the site distributes AMSI-bypass generation logic, which may be treated as suspicious by some defensive tools.
