FINDINGS ░▒▓

warningRust unsafe blockunsafe blocks bypass Rust's memory safety guarantees. Malware uses them for raw pointer manipulation, shellcode injection, or calling dangerous foreign functions.tgrep-cli/src/mem.rs


    unsafe {
        let handle = GetCurrentProcess();
        let mut counters = MaybeUninit::<PROCESS_MEMORY_COUNTERS>::zeroed();

            // accepts when it maps a file it is searching.
            Self::Mapped(map) => unsafe { std::str::from_utf8_unchecked(map) },
        }
    }

    // this never falls back to POSIX semantics when a mapped file rejects it.

Scores are heuristics. A “safe” verdict means no known-malicious patterns were found — clever malware can look boring. Wrong verdict? Flag it above; confirmed false positives become regression tests.
