Beware fake Chrome installers for Windows.
A file named "ChromeSetup.exe" is being offered for download on various websites, and the link to the file appears to be legitimately hosted on Facebook and Google domains. In reality, the software won't install Google's Chrome browser, but an information-stealing Trojan application known as Banker, according to antivirus vendor Trend Micro.
Once the malware--which appears to be targeting Latin American users, especially in Brazil and Peru--is executed, it relays the IP address and operating system version to one of two command-and-control (C&C) servers, then downloads a configuration file. After that, whenever a user of the infected PC visits one of a number of banking websites, the malware intercepts the HTTP request, redirects the user to a fake banking page, and also pops up a dialog box informing the user that new security software will be installed.
In fact, the malware has been designed uninstall GbPlugin, which is "software that protects Brazilian bank customers when performing online banking transactions," said Trend Micro security researcher Brian Cayanan in a blog post. "It does this through the aid of gb_catchme.exe--a legitimate tool from GMER called Catchme, which was originally intended to uninstall malicious software. The bad guys, in this case, are using the tool for their malicious agendas."
