February 27, 2015 — bluecollarpc https://bluecollarpcwebs.wordpress.com/2015/02/27/lenovo-slipped-superfish-malware-into-laptops-windows-8-1/ Lenovo Slipped Superfish Malware Into Laptops (Windows 8.1) If you have missed the security furor over Lenovo pre-installing adware (antispyware catagory of antimalware products) you may want to check out these news links for information, degree of danger, and most importantly removal instructions (easy). It is absolutely recommended to remove this immediately by all. Lenovo has been caught and publicly apologized. Just about all new computers come with what they used to call “bloatware” which is a handful of extra softwares which some may find useful. They take up space and may even slow down performance. But this is a big no-no Lenovo has done. It became as infamous as the Sony Rootkit malware they bundled in downloads, of music I believe it was, a good while ago. A snippet…. (Removal help/instructions below) “…The furor blew up because Lenovo installed Superfish adware on consumer laptops sold between September 2014 and January 2015. All these laptops were running Microsoft Windows 8.1. Your laptop fits the time frame, but you may have escaped for two reasons. First, Superfish was not installed on Lenovo’s business machines, such as ThinkPads. Second, it was not installed on laptops running Windows 7, which is still the business standard…..” SOURCE: http://www.theguardian.com/technology/2015/feb/26/how-can-i-find-and-remove-superfish-and-similar-malware LINKS: / PRESS US-CERT: Lenovo Superfish Adware Vulnerable to HTTPS Spoofing https://www.us-cert.gov/ncas/alerts/TA15-051A Lenovo Slipped ‘Superfish’ Malware Into Laptops malaysiandigest.com LenovoComputer maker Lenovo has been shipping laptops prepackaged with malware that makes you more vulnerable to hackers — all for the sake … http://www.malaysiandigest.com/technology/542592-lenovo-slipped-superfish-malware-into-laptops.html Lenovo computers come with pre-installed adware and MITM proxy Posted on Feb 19, 2015 10:45 am If you have recently bought a new Lenovo computer, you’re in for a nasty surprise: the company has been shipping them with pre-installed adware.

Overview Superfish adware installed on some Lenovo PCs install a non-unique trusted root certification authority (CA) certificate, allowing an attacker to spoof HTTPS traffic. Description Starting in September 2014, Lenovo pre-installed Superfish VisualDiscovery spyware on some of their PCs. This software intercepts users’ web traffic to provide targeted advertisements. In order to intercept encrypted connections (those using HTTPS), the software installs a trusted root CA certificate for Superfish. All browser-based encrypted traffic to the Internet is intercepted, decrypted, and re-encrypted to the user’s browser by the application – a classic man-in-the-middle attack. Because the certificates used by Superfish are signed by the CA installed by the software, the browser will not display any warnings that the traffic is being tampered with. Since the private key can easily be recovered from the Superfish software, an attacker can generate a certificate for any website that will be trusted by a system with the Superfish software installed. This means websites, such as banking and email, can be spoofed without a warning from the browser. Although Lenovo has stated they have discontinued the practice of pre-installing Superfish VisualDiscovery, the systems that came with the software already installed will continue to be vulnerable until corrective actions have been taken. To detect a system with Superfish installed, look for a HTTP GET request to: superfish.aistcdn.com The full request will look like: http://superfish.aistcdn.com/set.php?ID=[GUID]&Action=[ACTION] Where [ACTION] is at least 1, 2, or 3. 1 and then 2 are sent when a computer is turned on. 3 is sent when a computer is turned off. Superfish uses a vulnerable SSL decryption library by Komodia. Other applications that use the library may be similarly affected. Please refer to CERT Vulnerability Note VU#529496 for more details and updates. Impact A machine with Superfish VisualDiscovery installed will be vulnerable to SSL spoofing attacks without a warning from the browser. Solution Uninstall Superfish VisualDiscovery and associated root CA certificate Users should uninstall Superfish VisualDiscovery. Lenovo has provided a tool to uninstall Superfish and remove all associated certificates. It is also necessary to remove affected root CA certificates. Simply uninstalling the software does not remove the certificate. Microsoft provides guidance on deleting and managing certificates in the Windows certificate store. In the case of Superfish VisualDiscovery, the offending trusted root certification authority certificate is issued to “Superfish, Inc.” Mozilla provides similar guidance for their software, including the Firefox and Thunderbird certificate stores.
