New phishing campaign delivers Trickbot Trojan
Email spam campaigns are the most common methods for malware propagation, and this time cybercriminals are using the troublesome COVID-19 situation and the fact that many people are working from home (it is not the first time, and definitely not the last). Zoom, along with a few other similar programs, is used for online meetings and communication between employees when away from the office or other workplace.
In this phishing campaign, users are presented with an attachment that allegedly holds a special code that would allow accessing a conference call. Crooks abuse the fact that the unique code is commonly sent for this purpose – and that is exactly what they are trying to imitate. Inside the “Zoom Conference Invitation” file is TrickBot banking Trojan – the notorious malware that focuses on stealing sensitive user data on Windows systems, all while being invisible to victims.

Peculiarities of the attack and mitigation
Phishing is one of the most impactful and effective ways of spreading malware – especially when it comes to email spam. Hackers append a malicious attachment which is presented as an informative file for users – except that it is everything but that. Once a compressed file is opened, anything can be hidden inside, although victims never suspect that.
Cybercriminals commonly use intricate, advanced methods in order to make a fake email look legitimate, for example, they commonly use some well-known brand names, attributes, logos, context, and much more. In this case, however, the attackers didn't bother much and sent out a really primitive email. It includes the following text:
Subject: Zoom Invite XXXXXXX
Dear Valued Consumer,
Please find attached invitation.
The attachment, labeled Zoom_Conference_Invitation.zip, is a simple compressed ZIP file, which, once extracted, would produce a “Zoom_Conference_Invitation_1625.vs” file. Once opened, this file is capable of downloading the payload of malware – in this case, TrickBot.
Prevention measures, such as powerful security solutions – SpyHunter 5Combo Cleaner or Malwarebytes – can be used to stop the attack before it even begins. Security applications are designed to check the actions and code of certain files with the help of heuristic methods, which allow the prevention of further actions of the malicious file. These apps can also aid you with TrickBot removal, although you should refer to the bottom section for more details on this process.

If you want to know more about TrickBot…
TrickBot is a Trojan that was first discovered in 2016, and it's been targeting the customers of leading banks around the world. The virus has become well-known for its ability to mimic online banking windows and steal personal information like logins or passwords with help from Mimikatz post-exploitation tool.
Trickbot can also be used to siphon Bitcoin wallets, acquire access to email accounts, and then use those credentials laterally through other parts of your network/systems, meaning other people in your contact list might start getting spam emails boobytrapped with this malware.
It was no surprise that TrickBot had been actively performing attacks on CRMs and Payment Processors, as malware managed to hijack 250 million email accounts in 2019. In the year 2020, during a coronavirus pandemic, cybercriminals behind this virus employed medical advice and testing lures for users to click attachments containing malicious macro commands which they never were aware would be following through with their actions. Though it's unclear what is next for this type of attack or if new measures will have any effect against hackers who are determined to succeed despite all odds set forth by those holding back from them.
Phishing emails are often used to distribute the most dangerous malware
It seems like the Zoom Conference Invitation email virus is yet another try to spread malware to more users and companies. Unfortunately, victims are present at every campaign, despite the cybersecurity warnings during the COVID-19 pandemic.
Trojan removal can be easy, as long as adequate security tools are used
First of all, it is important to note that TrickBot is a sophisticated malware operated by a cybercriminal gang as malware-as-a-service (MaaS). It alters Windows operating system heavily, which might sometimes make it difficult to remove. Thus the first step we recommend is accessing Safe Mode:
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Click Restart.
- Press 5 or click 5) Enable Safe Mode with Networking.
Once you reach Safe Mode, launch SpyHunter 5Combo Cleaner or another reputable antivirus, update it with the latest definitions and perform a full system scan to eradicate malware and all its malicious components.
Note that if you have not extracted the “Zoom_Conference_Invitation.zip” file and opened the .VS file, your computer should be safe. However, we still strongly advise you to perform a full system scan with security software just in case.
After the malware is eliminated, we strongly recommend you contact your bank and explained that you were infected with Trickbot – the support should be able to assist you in ensuring your information and bank account remains secure. It is also advised to change all your passwords for all accounts and enable two-factor authentication where possible.
How to prevent from getting trojans
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
