TL;DR

A serious UEFI/firmware hack (active in the wild) targets Lenovo systems—attackers can persist across OS reinstalls.
In 3 simple clicks in BIOS/Lenovo Vantage, you can disable the affected component, restore firmware integrity, and block future infection.
Bottom sections include detection checks, recovery flow, and an affiliate-linked hardware hardening recommendation.

What’s the Vulnerability?

Security researchers and firmware analysts recently discovered a flaw in certain Lenovo UEFI modules that allows malicious payloads to be injected at boot time. The injected code survives OS reinstalls, making it extremely dangerous. (Intel, Lenovo, and third-party firmware trackers have issued alerts.)

While Lenovo has not publicly released full technical exploit details, the vector involves components tied to factory firmware updates and automatic firmware rollback. Devices that haven’t been patched or hardened are at risk.

The 3 Click Fix — Do This Immediately

Assuming your PC is a supported Lenovo model, here are three clicks (or toggles) you should do now:

Enter BIOS / UEFI settings (usually via F2, F12, or DEL when booting).
Disable “Automatic Firmware Update / Rollback” module or “Self-Recovery / Recovery service” — refer to Lenovo UEFI tab.
Enable secure boot + TPM verification (if currently off). Save & reboot — the firmware layer that enabled intrusion is now blocked.

Post-Click Checks: Did It Work?

Run `ls /sys/firmware/efi` (Linux) or check UEFI settings in Windows (via `msinfo32`) — see whether the disabled module is gone.
Use Lenovo’s “Firmware Integrity Check” or Vantage diagnostic to confirm no unauthorized modules remain.
Run an anti-rootkit / firmware scanner (e.g. Chipsec) to detect leftover anomalies.

Recovery Flow (If You Think You’re Infected)

Backup critical data immediately (without connecting to network).
Flash clean firmware image using official Lenovo firmware recovery tools or vendor USB recovery image.
Reinstall OS from internal media (don’t network boot until checks pass).
Reapply your 3-click settings above before restoring files to prevent reinfection.
Change all credentials including BIOS passwords, user accounts, and reset security tokens.

Hardware Hardening Recommendation

As an added layer of defense, using a **hardware-based firmware protection / management module** makes future attacks far harder.

Harden with a hardware security shield:
Consider using a TPM+firmware validation module such as the **[CYBERDUDEBIVASH Secure Boot Kit]** . Learn More & Buy Now

Why This Attack Works so Well

UEFI/firmware layer runs before OS; malware here cannot be removed by reinstalling the operating system.
Recovery/rollback modules often have elevated permissions and trust—attackers hijack them as a pivot.
Many users leave “automatic firmware update/rollback” features enabled by default, unaware of the risk.
