Windows users have been put on alert following security experts discovered malware on millions of laptops that is nearly impossible to remove, according to a report. site Express.
And if you’re wondering if your device has been affected and how to keep it safe, here’s what you need to know.
It appears that more than 100 models of laptop computers produced by the technology company “Lenovo” are affected by 3 critical vulnerabilities that allow hackers to secretly install malware, which is almost impossible to remove or even detect.
The vulnerabilities allow hackers to modify the Unified Extensible Firmware Interface (UEFI), the first piece of software that runs when a computer is turned on.
This interface is the link between a computer’s firmware and the operating system, and is present on a PC’s motherboard, making it difficult to detect and even difficult to remove.
The study, conducted by the information security company ESET, found vulnerabilities in more than 100 different models of Lenovo laptops. affordable devices such as the Ideapad-3, to more advanced devices such as the Yoga Slim 9.
Lenovo was informed of ESET’s findings last October, with the Chinese tech giant releasing an update in April that should keep affected users safe.
Speaking of the threat in Manifesto Online, ESET said, “UEFI threats can be hidden and very dangerous. They are executed early in the boot process, before control is transferred to the operating system, which means they can bypass all security measures.”
While the vast majority of affected devices are laptops that are still receiving updates, there are a number of older models that will not receive patches because they are not supported.
Advice to affected users how to stay safe, ESET said, “We strongly advise all Lenovo laptop owners to check the list of affected devices and update the device’s firmware, following the manufacturer’s instructions.
