"U.S Department of Labor" removal guide

What is "U.S Department of Labor"?

"U.S Department of Labor" is yet another Coronavirus/COVID-19-themed spam email campaign. These messages are disguised as official notices from the "U.S. Department of Labor Wage and Hour Division", informing recipients of the latest changes made to the "Employee Request Form under the Family and Medical Leave of Act (FMLA)". The emails advise people to carefully analyze the attached document, if they wish to request paid leave. In fact, if the malicious document is opened, it triggers the infection process of an information-stealing Trojan called TrickBot.

The emails entitled "This is a new Employee Request Form under the Family and Medical Leave of Act (FMLA)" state that such messages have been sent to all qualified workers. The emails are supposedly notifications concerning certain changes made to the "Employee Request Form under the Family and Medical Leave of Act (FMLA)" due to the Coronavirus/COVID-19 pandemic. These unspecified modifications to the FMLA must be studied, and for employee convenience, all significant corrections have been outlined within the enclosed document. The messages provide the date when these supposed changes will come into effect. If employees intend to demand paid leave, they are instructed study the form, complete it, and then send it to their HR department before the given date. Note that these "U.S Department of Labor" emails are scams. The attached files does not contain the information claimed - instead, they spread the TrickBot Trojan. The primary function of this malicious program is data theft. Therefore, as well as compromising system integrity, TrickBot infections can lead to financial loss, serious privacy issues and identity theft. If it is known or suspected that the TrickBot Trojan (or other malware) has already infected the system, it is crucial to use anti-virus software to remove it immediately.

Emails such as "U.S Department of Labor" are distributed by the thousand in large-scale operations termed "spam campaigns". The messages can have various disguises. Typically, they are presented as "official", "important" and "urgent", and often as mail from legitimate institutions, organizations, companies, service providers and so on. They can even exploit social climates or trends. For example, "COVID-19 test", "COVID-19 Part Time Employment", "COVID-19 Relief" and "COVID-19 Solution Announced by WHO" are other spam campaigns, using the Coronavirus/COVID-19 pandemic. Regardless of what these emails claim, request or demand, their purpose is the same: to generate revenue to the cyber criminals behind them. As well as spreading malicious software, spam campaigns are also used for phishing and other scams.

How did "U.S Department of Labor" infect my computer?

Systems are infected through dangerous files, distributed via spam campaigns. They can be attached to emails, or the messages can contain download links to the malicious files. These files can be in various formats such as Microsoft Office and PDF documents, archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), JavaScript, and so on. When infectious files are executed, run or otherwise opened, the infection process starts (i.e., it triggers malware download/installation). For example, Microsoft Office documents infect systems by executing malicious macro commands. In MS Office versions released before 2010, this process begins automatically once the document is opened, however, newer versions prompt users for permission to enable macros (i.e., to enable editing/content). Therefore, the infection is started only after macro commands are manually enabled.

How to avoid installation of malware

To avoid malware proliferated through spam campaigns, do not open dubious or irrelevant emails, especially those with any attachments or links found within them. You are advised to use Microsoft Office versions released after 2010, as newer version have "Protected View" mode. Therefore, when a dangerous document is opened, the infection process is not immediately initiated. Other common distribution methods of malicious programs are via untrusted download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation ("cracking") tools and bogus updates. Therefore, it is important to download only from official/verified sources, and activate and update products with tools/functions provided by genuine developers. To ensure device integrity and user safety, it is paramount to have reputable anti-virus/anti-spyware installed and kept up to date. Use this software for regular system scans and to remove detected/potential threats. If you have already opened "U.S Department of Labor" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
