Terdot banking Trojan has been around since mid-2016 and was originally designed to operate as a proxy to conduct man-in-the-middle (MitM) attacks. However, researchers at security firm Bitdefender have discovered that the new variant of Terdot has been revamped with new espionage capabilities. It can steal browsing information such as stored credit card information and login credentials and inject HTML code into visited web pages. The new variant has even added automatic update capabilities that allow the malware to download and execute files as requested by its operator.
