Zoom Exploits: Malware and Ransomware Threats
Malware Distribution via Zoom Remote Control Features
Hackers are exploiting Zoom's remote control functionality to infect devices with malware. This method relies on social engineering tactics to trick users into granting access, thereby allowing attackers to install malicious software or exfiltrate sensitive data. The cybercriminal group known as ELUSIVE COMET has been identified as a key perpetrator in these attacks. They employ a strategy that involves creating fake accounts and using them to establish a rapport with their targets, often through social media platforms.
Security experts emphasize that the attackers typically initiate contact with potential victims by offering media opportunities or interviews. Once a connection is established, they arrange a Zoom meeting, during which they send a remote control request disguised as a system notification. Victims, caught off guard or less tech-savvy, may inadvertently accept control requests. This grants the attacker full access to the victim's device, enabling them to install malware and steal sensitive information, including cryptocurrency.
To mitigate risks, it is advised to avoid accepting Zoom calls from unknown contacts and to disable remote control functionality during meetings. Organizations should also implement monitoring systems that flag suspicious activity and educate employees about the signs of phishing attempts.

Ransomware Threats from Fake Zoom Installers
Hackers are also deploying ransomware through fake Zoom installers. The BlackSuit ransomware gang has been identified as a major player in this scheme. Instead of downloading the legitimate Zoom application from the official website, users are misled to visit counterfeit sites that appear similar to the legitimate one. Once users download the fake installer, the ransomware becomes active, hiding on the system until it begins encrypting sensitive data and demanding a ransom for decryption.
The BlackSuit ransomware is particularly dangerous as it targets critical sectors, including healthcare and law enforcement. It uses a sophisticated method to ensure it remains undetected by standard security measures. After initially evading detection, it connects to a command server where additional malicious components are downloaded.
It is crucial for users to verify the authenticity of the sites from which they are downloading software. The official Zoom download page is at zoom.us/download, while the malicious site associated with this campaign is zoommanager.com.

Staying Secure in a Threatening Landscape
To protect against these types of threats, organizations and individuals should implement robust cybersecurity measures. Regular updates of antivirus software are essential, along with the adoption of additional security tools such as virtual private networks (VPNs) and password managers. Furthermore, being aware of common phishing tactics can significantly reduce the risk of falling victim to these attacks.
