Ethical hacker and security researcher Dymtro Oleksiuk revealed that Lenovo's computers have security vulnerabilities and hackers could bypass Windows security protocol to attack those computers.

Apart from expressing the concern about Lenovo computers, Oleksiuk also said that some of Lenovo's drivers are a direct copy from Intel, so he is worried that products of other manufacturers such as HP's Pavilion laptops might have the same security vulnerabilities.

In response to the remarks, Lenovo published and updated yesterday a statement about its "System Management Mode (SMM) BIOS Vulnerability". The company explained that the codes with the problem were not written by Lenovo, but provided by a third-party partner of Intel.

Lenovo added that the company is investigating the problem and will work together with cooperating partners to fix the problem as soon as possible.

In February 2016, Errata Security found that an ad-supported software on Lenovo computers called SuperFish was "designed to intercept all encrypted connections." SuperFish apparently resided on all Lenovo laptops registered after "mid-2013" and Lenovo issued patches after the Errata announcement.
