Trojan-Dropper.Win32.Dapato.bcbf

Trojan-Dropper.Win32.Dapato.bcbf is a Trojan that's used to install other types of threats that typically already are downloaded from hard-coded servers or already are included in its body. A recent spam campaign purporting to be from the United States Postal Service currently is underway distributing Trojan-Dropper.Win32.Dapato.bcbf in e-mail attachments that supposedly will allow recipients to gain more information about a failed package delivery. Deleting these e-mails unread is, of course, the safest reaction, but SpywareRemove.com malware researchers also recommend anti-malware scans for removing Trojan-Dropper.Win32.Dapato.bcbf or its payload if your PC does become infected.

When the Digital Delivery Man Has a Trojan for You

Like so many other Trojans that are widely distributed to both the general public and to specific targets in key positions, Trojan-Dropper.Win32.Dapato.bcbf uses e-mail to infect new PCs, with its spam messages being formatted to look like a routine communication from the USPS. Similar to delivery methods for past PC threats like TR/Barys.EB.34 or the German Troj/Agent-AAJO, Trojan-Dropper.Win32.Dapato.bcbf's e-mail claims that a failed delivery requires you to open an included file attachment to retrieve a relevant shipping number. This ZIP-archived file actually contains Trojan-Dropper.Win32.Dapato.bcbf rather than any sort of real USPS code.

Trojan-Dropper.Win32.Dapato.bcbf is installed with as little fanfare as possible, leading the victim to believe that nothing has happened after the file is opened. However, Trojan-Dropper.Win32.Dapato.bcbf is capable of installing additional threats onto your computer without its showing any symptoms of the installations. SpywareRemove.com malware experts often have connected such attacks to high-level threats such as spyware and banking Trojans, a la Trojan Zeus. Typical issues that may result from any Trojan-Dropper.Win32.Dapato.bcbf infections include:

• Keylogging (an attack that records your keyboard input).
• The theft of any browser-stored passwords and other sensitive information.
• Website injection attacks that alter a site to display malicious content.
• Cripled security programs such as Windows Defender, the firewall or Windows Task Manager.

Getting the Drop on Trojan-Dropper.Win32.Dapato.bcbf's Delivery

Although everything about Trojan-Dropper.Win32.Dapato.bcbf's infection strategy is quite stereotypical for a spam-distributed Trojan, Trojan-Dropper.Win32.Dapato.bcbf structurally is sufficiently different from past Trojans to evade identification by roughly three out of four reputable anti-malware programs. On one hand, SpywareRemove.com malware researchers do continue to suggest the use of updated anti-malware tools for deleting Trojan-Dropper.Win32.Dapato.bcbf or PC threats installed by Trojan-Dropper.Win32.Dapato.bcbf. However, there shouldn't be any need to do so in the first place if you avoid common infection vectors such as spam e-mails that are distributed suspicious ZIP files (this file format is often a simple way to obfuscate the threat's code and prevent easy analysis).

Since the real USPS has no business sending you ZIP files, deleting Trojan-Dropper.Win32.Dapato.bcbf e-mails as soon as they're seen is both an easy and obvious solution to its attacks. Any PC that already has been compromised by Trojan-Dropper.Win32.Dapato.bcbf is at risk of being affected by greater issues as noted earlier in this article.
