Is Zoom Conference Invitation email virus dangerous? What the senders want
From our report of Jul 2021 · not reviewed since
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:
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 - or - 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.
Once you eliminate the Zoom Conference Invitation email virus, you should also take care of Windows system health, as certain elements could get corrupted during the operation of malware.

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.
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.

Don't want to be infected with data-stealing malware? Don't click on "Zoom_Conference_Invitation.zip" file
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.
Unfortunately, only a handful of AV programs currently detects the file as malicious. If your cybersecurity software is up to date, you could see one of the following detection names:
- Trojan.GenericKD.46621081
- JS/Agent.A621!tr
- HEUR:Trojan-Downloader.Script.Agent.gen
- Trojan.KillProc2.16312
- Trojan.Downloader.Script.gen, etc.
What to do after the Zoom Conference Invitation email virus e-mail
If you only received the message and clicked nothing, step 3 is all you need.
If you clicked the link or typed anything on the page it opened, do every step, starting with the password.
Step 1: Change the password you typed on the fake page
If you entered a password after clicking the link in the Zoom Conference Invitation email virus message, treat that account as known to the sender.
Open the provider's real site by typing its address yourself, not through any link in the e-mail, and change the password there. Choose a new one you have never used before, and change it on every other account that shared the old one.
Then use the option to sign out of all other sessions or devices, if the provider has one. This works the same in any browser on Windows 11 and Windows 10.

Step 2: Turn on two-step verification
Two-step verification asks for a code from your phone or an authenticator app whenever someone signs in from a new device. A stolen password alone is then not enough to open the mailbox.
Turn it on in the security settings of the e-mail account first, then for the bank, shop and social accounts that send their reset links to that address.
While you are there, check the recovery e-mail and phone number and the forwarding rules, which attackers sometimes change to keep access. The settings pages look the same on Windows 11 and Windows 10.

Step 3: Report the e-mail and delete it
Report the message instead of only deleting it. In Outlook choose Report > Report phishing, in Gmail the three-dot menu > Report phishing; the provider then blocks the same message for other people.
Do not reply and do not click anything else in it. On a work account, forward it to your IT team as an attachment first. Web mail and the mail apps on Windows 11 and Windows 10 offer the same options.
New Outlook for Windows and Outlook on the web: Report > Report phishing. Full procedure with screenshots: Report a phishing e-mail
Step 4: Scan the PC if you opened a file from the message
A page that only asked for a password installs nothing, so most readers can skip this step.
If the Zoom Conference Invitation email virus e-mail or the page it opened made you download or open a file, delete it and run a full scan, then a Microsoft Defender Offline scan.
In Windows 11 and Windows 10 open Windows Security > Virus & threat protection > Scan options, select Microsoft Defender Antivirus (offline scan) and click Scan now. The PC restarts and the scan takes about 15 minutes, so save your work first.

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 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 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. 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.

Questions about Zoom Conference Invitation email virus
I opened the "Zoom Invite XXXXXXX" e-mail. Am I hacked?
No. Opening and reading a phishing e-mail does not give anyone access to your account or your PC. Modern mail programs block scripts and remote content by default, so reading the message "Zoom Invite XXXXXXX" only showed you text and pictures.
The danger comes from clicking the button and typing your password on the page it opens, or from opening an attached file. If you did neither, report the message as phishing and delete it.
If you clicked but closed the page without typing anything, there is also nothing to fix. If you did type a password, change it from another device and turn on two-step verification.
How fast do I need to react after signing in on the "Zoom Invite XXXXXXX" page?
As fast as you can. Stolen passwords are often tried within minutes, and the first thing an attacker usually changes is the recovery e-mail or phone, which locks you out. Change the password from a clean device first, then sign out everywhere and review the recovery settings.
If you are already locked out, use the provider's account recovery form straight away and mention that the page behind "Zoom Invite XXXXXXX" took your password. Warn your contacts, since a taken-over mailbox is often used to send the same phishing to them.
Is Zoom Conference Invitation email virus really from a well-known company?
No. It is sent by scammers who copy the name and look of a well-known company. The sender address and the links do not belong to it, and the message asks for your password, which a real company does not request through an unexpected message.
If you want to be sure about your account, open the website or app of a well-known company the way you normally do, not through the message, and look for notices there. Then delete the message and report it as phishing. If you already followed its instructions, use the steps in this guide for your case.
Is it true that your account needs urgent attention?
No. The claim that your account needs urgent attention is the hook of Zoom Conference Invitation email virus, invented to give you a reason to act quickly. Scammers pick a story that could plausibly apply to many people, so it may feel relevant to you, but nothing in the message is based on your real accounts or devices.
If the claim concerns a service you use, check it there directly, by opening the website or app yourself. You will find no such problem. Then delete the message and report it as phishing.
What happens if I do what Zoom Conference Invitation email virus asks?
The scammers get your password, and they use it quickly. Passwords are tried on the real service within minutes, cards are charged or added to phone wallets, remote access is used to open your bank, and crypto is moved on at once.
Documents surface later as accounts in your name. If you already did what the message asked, do not wait to see what happens; follow the steps in this guide for your case today. Speed matters more than anything else here.
Will a well-known company refund me if I fell for Zoom Conference Invitation email virus?
A well-known company did not send the message and is not responsible for it, so a refund usually comes from your bank or card issuer, not from the brand. Call the bank first if you paid.
It still helps to tell the real company: they can secure your account, add notes for their fraud team and take down pages that use their name. Contact them through their official website or app only, never through the message or a search ad. Keep the message as evidence.
How urgent is Zoom Conference Invitation email virus?
Urgent enough to act today, not urgent enough to panic. The sign reported, an e-mail with the subject "Zoom Invite XXXXXXX", means someone is using or testing your details. Changing the password and turning on two-step verification takes ten minutes and usually locks them out.
If a payment is involved, the sooner the bank knows, the better the chance of getting it back. Do not respond to calls or messages that arrive right after the incident, even if they claim to be from your bank: call the bank yourself.
Does receiving Zoom Conference Invitation email virus mean I was hacked?
No. A e-mail like this is sent to huge lists at once, and your address or number is on one of them, most likely because it appeared in a data breach or on a public page. Nothing on your PC caused it.
What would matter is whether anyone signed in to your accounts; check recent sign-in activity in your e-mail and bank accounts if you are worried. Turn on two-step verification for the important ones, then delete the message and report it as phishing.
Could malware on my computer cause Zoom Conference Invitation email virus?
It can, but it is not the most common cause. Information stealers copy saved passwords and session cookies from browsers, which can lead to an e-mail with the subject "Zoom Invite XXXXXXX". More often, the password came from a breach or a phishing page.
To be sure, run a full scan in Windows Security and check Installed apps and browser extensions. If anything is found, clean the PC first and change passwords afterwards from a clean device, because changing them on an infected PC lets the malware take the new ones too.
Will Fortect remove Zoom Conference Invitation email virus?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Zoom Conference Invitation email virus, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
