TrojanSpy:Win32/Usteal is a family of toolkit-created spyware programs that steal login information related to a wide range of programs, including instant messengers, e-mail clients, your Web browsers and even some brands of online games. TrojanSpy:Win32/Usteal family-based Trojans are distributed in two major ways: through being installed along with unrelated programs (usually ones related to illegal gaming activities, such as hack tools) or by being installed by other forms of Trojans, such as members of the Trojan.LockScreen family of ransomware. TrojanSpy:Win32/Usteal's variants do not, as a rule, show many major symptoms, but you may be able to detect TrojanSpy:Win32/Usteal through the malfunctions of some programs as they're being analyzed by TrojanSpy:Win32/Usteal's password-stealing attacks. SpywareRemove.com malware researchers, naturally, hope that you'll use appropriate anti-malware software whenever you need to find or delete TrojanSpy:Win32/Usteal, which is categorized as a high-level threat.

When Bending the Rules of Games Can Get You Bent in Turn

The toolkit that's used for making members of the TrojanSpy:Win32/Usteal family is publicly available, and, as a result, any variant of TrojanSpy:Win32/Usteal can display some minor deviations from the baseline behavior that's described in this article. As a rule, however, TrojanSpy:Win32/Usteal always is used to steal passwords and other stored confidential data from your computer, and always by targeting a range of specific applications.

Unlike other kinds of spyware, SpywareRemove.com malware researchers are happy to note that TrojanSpy:Win32/Usteal doesn't include keylogging attacks, and, therefore, can't steal information as it's being typed – in other words, the stolen data must be saved by another program before TrojanSpy:Win32/Usteal can steal it. Following this, one of the most easy ways to guard your personal information against being harmed by TrojanSpy:Win32/Usteal is to refrain from allowing any programs to save your login information and, instead, type this information as it's requested every time you use an account.

TrojanSpy:Win32/Usteal often is distributed through bundles with illegal or questionable programs, such as game cheat managers, pirated software and popular game customization utilities. SpywareRemove.com malware researchers also must emphasize that TrojanSpy:Win32/Usteal may be installed by other Trojans and, in some cases, includes its own features that enable TrojanSpy:Win32/Usteal to function as a Trojan downloader.

Surveying the List of TrojanSpy:Win32/Usteal's Greed

TrojanSpy:Win32/Usteal has been known to steal information from many types of applications, and SpywareRemove.com malware experts have, in particular, connected TrojanSpy:Win32/Usteal attacks to hijacks of accounts from the following types of software:

  • Instant messengers.
  • Website-based accounts (when the login data is saved by your Web browser).
  • Some online games, such as Full Tilt Poker or World of Tanks.
  • Various brands of FTP clients.

Many variants of TrojanSpy:Win32/Usteal will disable some programs temporarily, such as ICQ Messenger or the Mail.ru mail agent. They also often will self-terminate in any case of detecting a major brand of PC security software, which includes sandbox utilities and process-examining tools, as well as some types of anti-malware scanners.
