| Risk Type | Description | Mitigation | |-----------|-------------|-------------| | | A disguised .exe , .scr , or .bat file that installs ransomware, keyloggers, or remote access tools. | Scan with updated antivirus; open inside a VM or sandbox (e.g., Windows Sandbox). | | Script malware | JavaScript, VBScript, or PowerShell scripts that run when the archive is extracted. | Disable script execution for downloaded files; view contents without extraction using 7-Zip’s “Test” or “List” function. | | Exploit in 7-Zip itself | Old versions of 7-Zip had vulnerabilities (e.g., CVE-2018-10115) allowing code execution via crafted .7z files. | Keep 7-Zip updated (v23+). Use built-in Windows .zip handling if unsure. | | Password-protected payload | The .7z may be encrypted; the password is provided separately (common in warez releases). | Never run untrusted password-protected archives unless you fully trust the source. | | Information theft | Files may contain hidden metadata, tracking pixels, or “phone home” scripts that activate upon extraction. | Isolate extraction folder; monitor network traffic with WireShark or NetLimiter. |
