PWS:Win32/Ldpinch.UM

Detected by Microsoft Defender Antivirus

Aliases: Trojan.Win32.Dialer.qn (Kaspersky) Infostealer (Symantec)

Summary

PWS:Win32/Ldpinch.UM is detection for a group of general variants of Win32/Ldpinch, a family of password-stealing trojans. This trojan gathers private user data, such as passwords, from the host computer and sends the data to the attacker at a preset e-mail address. The Win32/Ldpinch trojans use their own Simple Mail Transfer Protocol (SMTP) engine or a web-based proxy for sending the e-mail, thus copies of the sent e-mail will not appear in the affected user's e-mail client.
Manual removal is not recommended for this threat. To detect and remove this threat and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742).
