| Risk Category | Description | |-----------------------------|-----------------------------------------------------------------------------| | Unknown origin | No official website, GitHub repository, or trusted developer documentation. | | Lack of digital signature | Legitimate flashing tools are signed. Unsigned executables can be modified. | | Hosted on suspicious sites | Often uploaded to mediafire, mega.nz, uploaded.net, or Russian/Chinese file hosts. | | Antivirus detection | When scanned with VirusTotal, many such tools trigger 15–40+ malware alerts (Trojan, Keylogger, RAT, Spyware). | | Requesting admin/root | Many “mobile tools” ask for administrator privileges on your PC, granting full system access. | | Potential for bricking devices | Incorrect or maliciously altered firmware can permanently damage the device. |
