Win32/Sinowal is a family of password-stealing and backdoor trojans. These trojans may try to find a cryptographic certificate on the infected computer and install a certificate on the computer to mislead users in Secure Sockets Layer (SSL) Web transactions. Some Win32/Sinowal components may also use advanced stealth functionality, or try to perform certain operations from the context of a trusted process such as explorer.exe in order to bypass local software-based firewalls.

Trojan:DOS/Sinowal.L is a component of Win32/Sinowal - a family of password-stealing and backdoor trojans. The trojan may try to find a cryptographic certificate on the infected computer and install a certificate on the computer to mislead users in Secure Sockets Layer (SSL) Web transactions. The trojan may also capture user data such as banking credentials from various user accounts and send the data to Web sites specified by the attacker. Some Win32/Sinowal components may also open a backdoor on a TCP port. Win32/Sinowal may try to perform certain operations from the context of a trusted process such as explorer.exe in order to bypass local software-based firewalls.

 

Trojan:DOS/Sinowal.L is a detection for a malformed MBR (Master Boot Record) generated by VirTool:WinNT/Sinowal. It loads the driver loader code of Sinowal when the affected computer boots.

This threat is classified as a Trojan - Password Stealer. Typically, a password stealing trojan installs a keystroke logger (commonly referred to as a keylogger) which records keystrokes and sends the recorded information to remote attackers. Some keyloggers monitor only keystrokes involved in specific types of web-based transactions. For example, a keylogger may include a component that monitors browser activity, only recording keystrokes when certain bank or ecommerce sites are accessed. Other types of password-stealing trojans include those that capture screenshots in an attempt to bypass graphic-based security measures. This threat is detected by the Microsoft antivirus engine. Technical details are not currently available.
