What is Spy.Delf Trojan?

Spy.Delf is a high-risk trojan designed to infiltrate the system and record sensitive information. Research shows that some variants of this malware are distributed using a fake Adobe Acrobat Reader installer. Note, however, that trojan-type viruses are often distributed using spam email campaigns that proliferate malicious attachments (in most cases, MS Office documents) that stealthily download and install malware into the system.

Spy.Delf Trojan malware

The fake Adobe Acrobat Reader installer distributes Spy.Delf Trojan simply by downloading the trojan rather than the Acrobat Reader. Spy.Delf Trojan is designed to record victims' email logins. Information is gathered from various email clients including Gmail Notifier, Group Mail, Pop Peeper, and so on (the full list is below). Data is sent to a remote server controlled by cyber criminals, however, some variants of Spy.Delf Trojan hijack cryptowallets and steal funds in various cryptocurrencies (Bitcoins, etc.) The presence of this malware can cause a number of issues. Firstly, cyber criminals can misuse gathered emails to steal your identity, and send spam. For example, criminals might abuse your identity, claiming to be in trouble and asking friends to "lend money". Furthermore, these people might steal thousands of dollars in various cryptocurrencies. As mentioned, Spy.Delf Trojan can cause serious privacy issues and significant financial loss. It is difficult to determine the presence of the Spy.Delf Trojan, since, to hide its traces, its associated executable is named "svchost.exe" (placed in the "%AppData%" folder). Note that the Windows Operating System has a legitimate "svchost.exe" file in a system folder, thus making it difficult to reveal the location and identity of Spy.Delf Trojan. In addition, Spy.Delf Trojan creates a number of Windows Registry entries, which are launched automatically on each Windows start. If you believe that your computer is infected with Spy.Delf Trojan, we strongly advise you to perform a full system scan with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

Spy.Delf Trojan shares many similarities with Adwind, FormBook, Emotet, TrickBot, LokiBot, and dozens of other trojan-type viruses. These viruses are also designed to record personal information. In some cases, however, trojans also proliferate other malware (in most cases, ransomware), and thus their presence might lead to chain system infections. Trojans pose a significant threat to your privacy and computer safety.

How did Spy.Delf Trojan infiltrated my computer?

As mentioned above, developers proliferate Spy.Delf Trojan using a fake software installer. This method is very popular amongst cyber criminals who develop ransomware-type viruses. Fake updaters/installers infect the system by exploiting outdated software bugs/flaws or simply downloading and installing viruses rather than the promised updates/software. Note however, that trojans are often distributed using spam email campaigns. Cyber criminals proliferate malicious attachments designed to execute commands that stealthily download and install malware.

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Never open any email attachment that seems irrelevant or has been received from a suspicious/unrecognizable email address. These emails should be deleted immediately, without reading. Furthermore, download your applications from official sources only, using direct download links - third party downloaders/installers are likely to proliferate rogue apps or even high-risk viruses. The same applies to software updates. It is important to keep installed applications up-to-date, however, this should be achieved through implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If you believe that your computer is already infected with Spy.Delf Trojan, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
