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?
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 Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Malicious attachment ("FMLA-instr.doc") distributed via "U.S Department of Labor" spam campaign:
Update January 20, 2022 - We found new "U.S Department of Labor" (DoL) scam emails. The fake letters are designed for phishing recipients' account log-in credentials (the analyzed samples targeted Microsoft 365 passwords).
These letters invite recipients to make bids on government projects. What is noteworthy is that most of the variants were sent from email addresses masquerading as the legitimate ones used by DoL. These emails have a PDF document attached to them, which contains a link ("BID" button) redirecting to a phishing site.
Carefully crafted, the pages appear nigh indistinguishable from the legitimate United States Department of Labor (dol.gov) website. They even mimicked its domain, observed instances include: bid-dolgov[.]us, dol-bids[.]us, dol[.]global, dolbids[.]com, open-biddolgov[.]us, openbid-dolgov[.]us, openbids-dolgov[.]com, openbids-dolgov[.]us, opendolbid[.]us, us-dolbids[.]us, usdol-gov[.]com, and usdol-gov[.]us.
When our researchers attempted to sign in through the webpage - it claimed that the entered information was incorrect. The second attempt resulted in a redirect to the real DoL website.
The scammers behind these emails use this tactic to deflect user suspicion and extend the timeframe until they realize their accounts have been exposed. Meanwhile, the cyber criminals can abuse the "incorrectly entered" credentials, gain access/control over corresponding accounts, and cause a wide variety of damage.

Types of malicious emails:
Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.
Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.
After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.
Emails with Malicious Attachments
Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.
In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.
If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.
While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.
This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.
To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.
How to spot a malicious email?
While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:
- Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
- Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
- Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
- Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.
To minimise the risk of opening phishing and malicious emails we recommend using Combo Cleaner Antivirus for Windows.
Example of a spam email:
What to do if you fell for an email scam?
- If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
- If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
- If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
- If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using Combo Cleaner Antivirus for Windows.
- Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.
Frequently Asked Questions (FAQ)
Why did I receive this email?
Spam emails are not personal. Cyber criminals distribute them in large-scale campaigns; hence, thousands of users receive identical letters.
I have provided my personal information when tricked by this spam email, what should I do?
If you have disclosed credentials, immediately change the passwords of all potentially compromised accounts and inform their official support. If the provided information was of a different personal nature (e.g., credit card numbers, ID card details, etc.) - contact the relevant authorities without delay.
I have read a spam email but didn't open the attachment, is my computer infected?
No, simply reading a spam email will not result in a malware infection. The attachments and links present in these letters can cause infections when opened/clicked.
I have downloaded and opened a file attached to a spam email, is my computer infected?
That depends on the file and its purpose. There are several variants of the "U.S Department of Labor" scam emails. Some contain files that redirect users to phishing websites - hence, opening these will not trigger any infection processes. Other versions proliferate virulent files, and whether opening these will result in a system infection - relies on their formats. Executables can cause infections upon opening practically without fail. While documents (e.g., .doc, .xls, .pdf, etc.) may require additional user interaction (e.g., macro command enablement) to start downloading/installing malware.
Will Combo Cleaner remove malware infections present in email attachments?
Yes, Combo Cleaner can detect and eliminate almost all of the known malware infections. However, performing a full system scan is a must - since sophisticated malicious software hides deep within systems.
