Do not call the numbers provided in the BazarCall email campaign
Written by Tomas Meskauskas on (updated)
What is BazarCall scam?
BazarCall is the name of the email campaign used with the purpose to trick recipients into installing malware on their computers. Cybercriminals behind this campaign send subscription-themed emails encouraging recipients to call the provided phone number to cancel or renew a subscription plan.
After calling the provided number, recipients are usually asked to visit a malicious website and download a file designed to install malware. Research shows that the BazarCall campaign is used to distribute BazarLoader malware that provides the attackers backdoor access to the infected computers.
It is possible that this campaign is used to deliver other malicious software as well.
BazarCall scam overview
There are multiple BazarCall campaign variants used to trick recipients into infecting their computers with BazarLoader (or other malware). The main differences between them are the number that recipients are asked to call and the name of a company name cybercriminals use as a disguise.
It is known that one email is disguised as a letter from Paradise Books asking to call the +1-816-307-4271 number, and another one disguised as a letter Medical Reminder Service asking to call the +1-816-897-0374 number. Although, it is likely that there are other variants with different company names and telephone numbers.
The main purpose of these emails is to trick recipients into believing that some subscription is expiring soon/trial period is almost over and calling the provided number to extend or cancel that subscription. Once called, the scam can vary.
Often (following a potentially lengthy conversation concerning verification, cancellation, security, etc.) victims are asked to visit a website, then download and execute (open) a file. If the file is infectious, once opened - it triggers malware download/installation processes.
Research shows that at least one of the websites is hosting a malicious Microsoft Excel document designed to install BazarLoader. Nevertheless, those pages may be designed to download other files designed to install other malware.
BazarLoader functions as a backdoor trojan - it installs additional malware. It is known that one of the malicious programs that this trojan is used to distribute is the RYUK ransomware.
Ransomware is a type of malware that encrypts files and keeps them inaccessible unless victims decrypt them with a decryption tool purchased from the attackers. Although, BazarLoader may be used to distribute other ransomware, cryptocurrency miners, remote access trojans, etc.
Typically, cybercriminals use malware like BazarLoader to distribute malicious software designed to encrypt files, steal personal information, mine cryptocurrency, or provide the attackers a remote access to the infected computer.
However, users may be asked to download a legitimate file, such as an installer for a remote access tool (e.g., AnyDesk, TeamViewer, UltraViewer, etc.). Scammers can use various excuses to access victims' devices, e.g., aid with refund processes, security checks, malware/hacker removal, etc. The end result is often an actual malware infection, but it can also be accompanied by fake fees or other scams aimed to extract money from victims.
In most cases, recipients who fall for these scams become victims of identity theft, suffer monetary loss, lose access to personal accounts, files stored on their computers, and (or) encounter other problems. Therefore, emails of this type have to be ignored and reported.

Another example of an email scam used to trick users into calling the provided number and then downloading a malicious file designed to infect computers with malware is "Your Free Trial Period Is Almost Over Email Scam" (this article contains a number of examples of emails used to trick recipients into installing the BazarLoader malware).
Other examples of similar email spam campaigns include "Apple Invoice email scam", "Windows Defender email scam", "Geek Squad email scam", "Windows Defender Advanced Threat Protection email scam", and countless others.
As a rule, cybercriminals behind such emails pretend to be legitimate companies, organizations, service providers, or other genuine entities.
How do spam campaigns infect computers?
It is known that one of the files used to distribute BazarLoader via the BazarCall campaign is a malicious Microsoft Excel document. That document installs malicious software only if users enable macros commands (editing/content).
Although, malicious documents opened with Microsoft Office versions released before Microsoft Office 2010 install malware without asking to enable macros commands. It is because those versions do not have the "Protected View" mode, which prevents malicious documents from installing malware right after they are opened.
How to avoid installation of malware?
Avoid opening files downloaded from questionable websites, via Peer-to-Peer networks, third-party downloaders, and so on. It is safe to open files or use programs that were downloaded from legitimate pages and via direct links.
Another important thing is not to open files or website links in irrelevant emails that are received from suspicious or unknown senders. Quite often, emails of this kind contain malicious files, links designed to deliver malware. Installed operating system and software should be kept up to date.
It has to be achieved using implemented functions, tools provided by the official developers. It is strongly recommended not to trust any other tools (unofficial, third-party updaters, or 'cracking' tools).
It is common that those tools are bundled with malware. Another detail about 'cracking' tools is that it is illegal to use them to bypass software activation.
Additionally, it is advisable to scan the operating system for viruses regularly and do it using reputable antivirus or ant-spyware software. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.
If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK.
During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button.
In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files.
After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
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 Combo Cleaner Antivirus for Windows.
Frequently Asked Questions (FAQ)
Why did I receive this email?
This mail is not personal; thousands of users receive identical emails.
I have provided my personal information when tricked by a scam, what should I do?
If you have disclosed account credentials - immediately change the passwords of all potentially compromised accounts and inform their official support. And if you've provided other private data (e.g., ID card details, credit card numbers, etc.) - contact the appropriate authorities without delay.
I have allowed cyber criminals to remotely access my computer, what should I do?
If you have allowed cyber criminals to access your device remotely, you must first disconnect it from the Internet. Afterward, uninstall the remote access software that the criminals used (e.g., TeamViewer, UltraViewer, AnyDesk, etc.) since they may not need your permission to reconnect. Lastly, use an anti-virus to perform a full system scan and remove all detected threats.
I have read a scam email but didn't open any files promoted through it, is my computer infected?
No, merely reading/opening an email will not trigger any system infection processes. Devices are infected when malicious files or links are opened/clicked.
I have downloaded and opened a file promoted through a scam email, is my computer infected?
Whether your system was infected might depend on the opened file's format. If it was a malicious executable (.exe, .run, etc.) - most likely, yes - your device was infected. However, you might have avoided an infection if it was a document (.doc, .pdf, .xls, etc.). Virulent files in these formats can require extra interactions (e.g., enabling macro commands) to begin downloading/installing malware.
Will Combo Cleaner remove malware infections?
Yes, Combo Cleaner is designed to detect and remove threats. It can eliminate most of the known malware infections. Keep in mind that running a full system scan is essential - as sophisticated malicious programs tend to hide deep within systems.
