You see this notification pop up:
"Your Dell Computer May Be at Risk. Please update your device firmware immediately."
Why did this happen?
You received this notification because of recently reported vulnerabilities affecting Dell computers.
What is the issue?
These vulnerabilities can be exploited through man-in-the-middle attacks. Attackers can gain remote access to affected devices and compromise networks.
The reported vulnerabilities were discovered in BIOSconnect - a Dell feature that allows users to download firmware updates easily. BIOSConnect is part of Dell’s SupportAssist update feature, which has previously had a vulnerability.
What are its risks?
- An attacker can take full control of the computer.
- Once the firmware is compromised, the vulnerability may remain undetected inside the network.
What should I do next?
- Check if your Dell Computer model is affected by this vulnerability here.
- Update to the latest Dell Client BIOS version as soon as possible. Because the vulnerable component (BIOSConnect) is used when updating firmware, we recommend that you get the updates from Dell’s Drivers & Downloads website and manually download and install the updates from there.
- Make sure Trend Micro Home Network Security is plugged into your home network and activated. Show me how.
