One of the most popular computer manufacturers Lenovo is being criticized for selling laptops pre-installed with invasive marketing software, or malware that, experts say, opens up a door for hackers and cyber crooks.

The software, dubbed 'Superfish Malware', analyzes users' Internet habits and injects third-party advertising into websites on browsers such as Google Chrome and Internet Explorer based on that activities without the user's permission.

Security researchers recently discovered Superfish Malware presents onto new consumer-grade Lenovo computers sold before January of 2015. When taken out of the box for the first time, the adware gets activated and because it comes pre-installed, Lenovo customers might end up using it inadvertently.

The Superfish Malware raised serious security concerns about the company's move for breaking fundamental web security protocols, carrying out "Man in the Middle" (MitM) attacks - impersonating the security certificates of encrypted websites in order to monitor users' behavior even on protected sites.

This would trouble Lenovo users because MitM attack can open a door for hackers to potentially compromise the sensitive information of any customer affected by Superfish - like passwords or banking details - because users' data isn't actually being protected.

Anyone with the password that unlocks that single password-protected certificate authority would be able to completely bypass the computer's web encryption.

According to a post by Errata Security's Robert David Graham, he cracked and published the password which was stored in the Superfish software's active memory and was trivial to extract. So, one could imagine the loss, if the same would be done by any hacker or cyber crook.

After the news fired up over the Internet and multiple users complained of popups and other unwanted behavior, the computer giant removed the Superfish Malware.
"We have temporarily removed Superfish from our consumer systems until such time as Superfish is able to provide a software build that addresses these issues. As for units already in market, we have requested that Superfish auto-update a fix that addresses these issues," a Lenovo community administrator, Mark Hopkins, wrote in late January.
Hopkins also defended the company from criticism over installing Superfish in the first place — but it didn't address the false HTTPS certificate problem. He also says that Lenovo users can refuse the terms and conditions when setting up their laptop in order to disable the software.
"To be clear, Superfish technology is purely based on contextual/image and not behavioral," Hopkins' statement reads. "It does not profile nor monitor user behavior. It does not record user information. It does not know who the user is."
While other users on online forums are reporting that Superfish Malware actually installs its own self-signed certificate authority which effectively allows the company to snoop on secure connections. And if true, Superfish Malware could be far more dangerous than we had thought.
"A blatant man-in-the-middle attack malware breaking privacy laws. I have requested return of the laptop and refund as I find it unbelievable that ... Lenovo would facilitate such applications pre bundled with new laptops," the user wrote on the Lenovo forums.
Facebook engineering director Mike Shaver also warned about the invasive adware via his personal Twitter account, saying that he found SuperFish certificates posted by different users who had shared the same RSA key.
"Lenovo installs a MITM cert and proxy called SuperFish, on new laptops, so it can inject ads? Someone tell me that's not the world I'm in," Shaver tweeted.
The company this morning issued a weird statement addressing the controversy on the Lenovo computers. According to the computer giant, the Superfish software was "to help customers potentially discover interesting products while shopping."
"The relationship with Superfish is not financially significant," the statement reads. "Our goal was to enhance the experience for users. We recognize that the software did not meet that goal and have acted quickly and decisively."
What was my reaction on the fresh statement issued by the company? Oh! Come on Lenovo, we know the reality. May be you are one of the world's largest PC brands, but after all you are also a Chinese PC brand.

In order to remove Lenovo Superfish Malware from your system, run the Microsoft Management Console (mmc.exe), and do the following:
  1. Go to File and Click Add/Remove.
  2. Choose Certificates, click Add.
  3. Choose Computer Account, click Next
  4. Choose Local Computer, click Finish
  5. Click OK
  6. Look under Trusted Root Certification Authorities -> Certificates
  7. Find the one issued to Superfish and delete it.
This isn't first time, in past the computer giant was caught installing malware backdoors in its products and was also banned by different countries for same reasons.

In the mid of 2013, the spy agencies - the 'five eyes' alliance of the US, Britain, Canada, Australia, and New Zealand - banned Lenovo for allegedly installing backdoor into Lenovo-brand circuit boards, along with other vulnerabilities discovered into the firmware.
