What is TrickBot?

TrickBot is trojan-type malware designed to steal users' private data. Research shows that, in most cases, developers proliferate TrickBot using spam emails, however, it might also be distributed using fake Adobe Flash Player updates. This virus was first identified in late 2016 targeting various financial institutions, banks, and credit card providers (for more information click here). In late 2017, cryptomining became very popular, and for this reason, TrickBot was updated and now also targets cryptowallets. Besides, TrickBot can spread itself further and infect as many computers as possible.

TrickBot malware

This malware essentially hijacks web browsers and modifies websites displayed by them. The sites are modified such that entered logins and passwords are recorded and sent to a remote server controlled by cyber criminals. This is a significant issue regarding users' privacy. By stealing login details and passwords for cryptocurrency wallets, PayPal, bank accounts, and other personal accounts, cyber criminals cause serious problems and transfer money without consent, thus leading to financial loss. More recent versions of TrickBot are capable of locking victim's computer screen. Cyber criminals can use this feature to force people to pay a ransom so they could access their computers again. Also, this virus is capable of hijacking various applications (such as WinSCP, Microsoft Outlook, Filezilla, Mozilla Firefox, Google Chrome, Microsoft Edge, Internet Explorer) and stealing saved passwords, autofill data and a number of other information types. It is designed to steal this data with a implemented module called "pwgrab". Aside from stealing credentials, TrickBot also records information relating to web browsing (e.g., history, cookies, and so forth), as well as the system itself (CPU, operating system, running processes, etc.). To steal data from browsers it uses a cookies-grabbing module. This module is used to steal web browser cookies which help cyber criminals to create a better profile of each victim and to optimize the attack in a better way. Newer versions of TrickBot are also capable of stealing PIN codes from people who use services of Verizon Wireless, T-Mobile, and Sprint. This feature allows cyber criminals to take control over victim's phone numbers. To achieve it, TrickBot alters web content of visited websites (like Verizon Wireless) using new dynamic webinjects. It can add or remove various fields, change texts and so on, depending on what cyber criminals willing to achieve. It can also be used to get access to previously infected networks (bots) and allows other threat actors to further infiltrate the network and drop their payloads. Note that this virus is capable of updating itself after the infection. In other words, each victim (if there's an Internet connection, of course) will have the newest version of TrickBot, no matter when this malware has firstly infiltrated the system. This malware should be eliminated immediately, however, TrickBot is notorious for hiding itself - on initial inspection, it is virtually impossible to determine if this malware is present. It's detection avoiding capabilities have increased significantly. Besides, it is capable of disabling Windows Defender. Fortunately, most legitimate anti-virus suites are capable of detecting and removing TrickBot. If you have recently downloaded/opened suspicious email attachments or used third party Adobe Flash Player update tools, you should immediately use a reputable anti-virus software to scan the entire system and eliminate all listed threats. In addition, check the list of installed applications/browser plug-ins and uninstall any suspicious entries (fake updaters are also likely to include potentially unwanted adware-type programs).

TrickBot shares many similarities with Adwind, Pony, FormBook, and a number of other trojans. Although these viruses work in different ways, their purpose is identical - to gather personal information. Malware such as TrickBot is released simply to generate revenue - developers literally steal other users' money. Potentially unwanted programs are also designed to help developers generate passive revenue - most deliver intrusive advertisements (via the "Pay Per Click" [PPC] advertising model), cause unwanted redirects (promotion of dubious sites), and gather data (e.g., IP addresses, websites visited, pages viewed, search queries, etc.) PUPs are also known to offer various 'useful features', however, these claims are merely attempts to give the impression of legitimacy - they deliver no real value for regular users.

How did TrickBot infect my computer?

As mentioned above, TrickBot is promoted using spam emails and fake Adobe Flash Player updaters. Spam emails contain various malicious attachments (e.g., PDF files, MS Office documents, etc.) By opening these attachments, users execute scripts that stealthily download and install viruses such as TrickBot, whilst Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware/PUPs rather than updates. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of malware?

To prevent computer infections, be very cautious when browsing the Internet. Think twice before opening email attachments. If you suspect that an email is irrelevant and is sent from a suspicious/unrecognizable email address, immediately delete it and certainly do NOT open any attachments. Note that cyber criminals use various tactics to make these emails seem legitimate - they imitate bank notifications, job offers, and so on. Therefore, if you receive any unexpected/suspicious emails, delete them immediately. As with updating software, remember that criminals proliferate malware via fake updaters. Therefore, software should be updated using implemented functions or tools provided by the official developer only. The same rule applies to software download/installation. Criminals monetize third party downloaders/installers by promoting ("bundling") PUPs. Therefore, software should be downloaded from official sources only, using direct download links. When downloading, opt-out of all additionally-included programs and if you are unable to do so, cancel the entire process. The key to computer safety is caution. If your computer is already infected with TrickBot, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Update September 13, 2019 - Cyber criminals have recently started using an interesting technique to distribute TrickBot trojan. They use email spam campaigns to spread a malicious Microsoft Word document. The tricky part is that the content of the said document is JavaScript code - it contains tens of thousands of JavaScript code lines within. In order to hide them, cyber criminals change the text color to white and, since the background is also white, the text becomes invisible, thereby tricking inattentive users into thinking that the document is empty. Once opened, the document runs a macro command which extracts the its content to a local file and the entire JavaScript code (which injects TrickBot into the system) is eventually executed. Now it is worth mentioning that even though there are thousands of code lines, only a small portion is actually used. Cyber criminals simply insert lots of code lines with an intention of making it troublesome for malware researchers to analyze the code.
