| Step | Action |
|------|--------|
| 1 | Check hardware revision – Log into the router (usually 192.168.1.1) and look for the exact model number and PCB version. |
| 2 | Match firmware region – EU, Asia, and Latin America versions have different wireless channels and ADSL annexes. |
| 3 | Compute SHA-256 – Compare with known good hashes from trusted archival projects (e.g., The-Digital-Picture or DSL-Reports archives). |
| 4 | Validate file size – Official HG520b firmware is typically 3–5 MB. Anything larger or smaller is suspicious. |
| 5 | Scan for malware – Use VirusTotal before opening or uploading to your router. | | Source Type | Legitimacy | Recommendation |
Upload the file to VirusTotal. A clean firmware file should have a 0/60 detection rate. If any engine flags it as a “Linux.Mirai” or “Trojan.Dropper,” delete it immediately.
