The other sample Backdoor. Interestingly, both compromised installers installed a legitimate version of Zoom, likely to hide evidence of malicious activity from the user. Aside from using compromised installers, we also found instances where malicious actors bundled legitimate installers with malware files.

This malware variant allows its operator to execute commands remotely, such as adding or deleting files, recording keystrokes, and gathering information. A , a trojan that also comes bundled with a legitimate Zoom installer.

We also found an email sample where a malicious actor tried to extort money from the victim by threatening them with the release of compromised video footage — allegedly acquired via a hacked camera. We found evidence of attacks that integrate other communication services — specifically Slack and Discord — into their routines. Slack has earned a loyal following over the years, with over 10 million daily active users as of However, we also found evidence of malicious actors making use of some of its features.

We recently found a ransomware variant Ransom. C that, on the surface, seems fairly standard in terms of capabilities. It encrypts files with the following extensions after which it will append the. Currently, it only sends back a minimal amount of data, namely computer and user names, the number of infected files, and the infection timestamp — indicating that the use of Slack for infection status reporting might still be in its testing phase.

Discord is another communication software that shares similar features with Slack while also being notable for its widespread use in gaming communities. We found samples that show how malicious actors are using Discord as part of a campaign involving malicious spam emails that eventually end in an AveMaria or AgentTesla malware infection.

We first observed the use of malicious spam to deliver these malware families in — however, the addition of Discord as part of its attack routine is relatively recent. The malicious emails are typically either postal delivery notifications or invoices with an included DHL or TNT-themed attachment:.

The Whiteboard has proven to be a very useful addition to Zoom, and now the company wants to promote its use in all applications in its ecosystem. Users can create a whiteboard in the main menu or directly in the web version of Zoom.

Because this is a persistent feature, user-generated or shared Zoom Whiteboard files are saved to the cloud. The new update also implements one-time passwords for those who haven't enabled two-step verification.

If Zoom detects a suspicious login, it will email the login password. This layer of security includes sending a unique key that expires when entered. The latest patch 5. This means that if messages increase, the app will turn off notifications to prevent attendees from being distracted. A tag engine has also been implemented to react to certain words or phrases in group chats.

Administrators can set policies to follow when users send unauthorized messages. Other features include Waiting Room enhancements, maximum capacity during events, emoji reactions in Webinar, a centralized survey catalog, an artificial intelligence-based sales solution called Zoom IQ, and more. Zoom automatically adds passwords to accounts, and those passwords can be embedded in meeting links.

For this reason, when scheduling a meeting, Zoom assumes that you want to use the automatically generated unique meeting ID instead of the personal meeting ID. In fact, there is no reason to use that personal identification.

Another possible reason that explains these programs' use is that they can pass off as normal legitimate network communication. Their popularity also amounts to a high chance that employees and end-users are already using these services. Fortunately, defending against these types of attacks is relatively straightforward.

In the case of the Zoom installers, the commonality between the attacks is that they are downloaded from places other than the official Zoom download page. The simplest way to avoid infection is to download communications apps and all apps in general only from official channels.

This will ensure that the software is free from tampering. Users should also avoid clicking on any links or downloading attachments from suspicious or unverified emails. If unsure, it would be a good idea to double-check with the alleged sender to confirm if they were the ones who sent the email.
