CyberCX Experts Unveil Vulnerability in Lenovo Laptops with BIOS Locked

Cybersecurity experts at CyberCX have recently discovered a vulnerability in older Lenovo laptops with a locked BIOS. This discovery has raised concerns about the security of personal data stored on abandoned or discarded laptops. In this article, we will explore this discovery in detail and discuss preventive measures to ensure maximum security.

Methods to bypass BIOS password

During the discovery, executives at CyberCX elaborated on a simple method to bypass the BIOS password using a screwdriver to connect specific pins on the EEPROM chip. This method is effective in bypassing the BIOS password on several Lenovo laptops that have been inactive for some time.

Demonstration on Discarded Laptops

The demonstrations on Lenovo laptops were carried out on several discarded laptops that were no longer in active use. These laptops revealed a vulnerability in the BIOS due to the EEPROM chip being separate from the primary BIOS chip. This vulnerability can lead to unauthorized access to the laptop’s data.

Identifying the BIOS EEPROM

Researchers at CyberCX have identified that Lenovo laptop motherboards use an 8-Pin TSSOP for the EEPROM. With this information, they were able to identify the BIOS EEPROM on a Lenovo laptop. They discovered that by inspecting chips that appeared promising on the mainboard and researching their series numbers, it was possible to pinpoint the correct EEPROM to target.

To bypass the BIOS password, it was found that the vulnerable L08-1 X chip could be easily shorted by placing a screwdriver tip between two of its legs. Implementing this step requires caution, and users are strongly advised to seek expert guidance before attempting to bypass the BIOS password.

Reading the Oscilloscope

When shorting the L08-1 X chip, it is important to read the oscilloscope carefully to ensure the safety of the motherboard. When reading the oscilloscope, the yellow line represents SCL (Clock), and the purple line represents SDA (Data).

Preventive Measures

To ensure maximum security, it is essential to implement preventive measures to protect your older laptop. Here are some preventive measures that you can implement today:

1. Keeping your laptop up-to-date with the latest software updates and patches.

2. Enabling encryption features on your hard drive can be helpful in protecting sensitive data.

3. Avoid unsecured Wi-Fi networks and always use firewalls.

4. Limit physical access to your laptop, especially when in public areas.

Disabling the BIOS password is recommended if your laptop is no longer in use.

In conclusion, the discovery of a vulnerability in Lenovo laptops with locked BIOS is a major concern. However, by implementing the preventive measures discussed above, you can maximize the security of your older laptop with minimal effort. It is always important to remain vigilant and seek expert advice when dealing with sensitive data.
