Beware of the CTB Locker Ransomware Virus Posing as a "Chrome Browser Security Update

2015-02-10

Recently, some Baidu Antivirus users reported that they received an email from Google with the warning: "Your version of Google Chrome is potentially vulnerable and out of date". When these users attempted to update Chrome as prompted by the message, they discovered that Baidu Antivirus unexpectedly prevented them from downloading the file. 

 

 

Baidu Antivirus security experts explain that the reason Baidu Antivirus prevents users from downloading the so-called Chrome update is because the download address has been flagged as a malicious link by the Baidu Antivirus Security Center. Baidu Antivirus security experts have confirmed through analysis that if users access the malicious web address, they will download a virus called ChromeSetup.exe, which is classified as a file from CTB Locker, a well-known member of the ransomware family. After users open the .exe, myriad files on their computer – including photos, music, documents and more – will be encrypted by CTB Locker. Only by paying a (potentially hefty) ransom will they be able to once again access their valuable data.

 

Within only a few hours, Baidu Antivirus Security Center intercepted many malicious addresses put out by the CTB Locker ransomware virus. Baidu Antivirus security experts would like to take this opportunity to alert all users that cybercriminals are very good at social engineering to entice people into opening viruses and trojans. If you encounter a well-known program that requires a downloadable update, you should go directly to the official download center to download the file, so as to avoid infection by CTB Locker and other such ransomware viruses that may cause irreversible damage and financial loss.
