Zoom Platform Misused by Elusive Comet Attackers in Fraud Scheme

 


Recent reports suggest that North Korean threat actors are now employing an alarming evolution in the tactics they employ to launch a sophisticated cybercrime operation known as Elusive Comet, a sophisticated cybercrime operation. This newly uncovered campaign demonstrates a way of exploiting Zoom's remote control capabilities to gain unauthorised access to cryptocurrency industry users' systems. 

It is clear from this development that a significant trend is occurring in which widely trusted communication platforms are being exploited as tools to facilitate high-level cyber intrusions. Security Alliance, one of the most reputable cybersecurity research organisations, conducted the investigation and analysis that led to the discovery. Elusive Comet exhibited some significant operational similarities to activities previously associated with North Korea's notorious Lazarus Group, a group which has been linked to North Korea for some years. 

The findings suggest that definitive attribution is yet to be made. Due to the lack of conclusive evidence, attempts to link this campaign with any known state-sponsored entity have been complicated, further demonstrating how covert cyberattacks have become increasingly common in the financial sector. This campaign, according to security experts, marks a dramatic departure from the traditional methods of gaining access to cryptocurrency targets previously used to attack them. This is because the attackers can leverage legitimate features of mainstream platforms such as Zoom, which not only makes their operations more successful but also makes detection and prevention much more difficult. 

Using such ubiquitous communication tools emphasises the need for enhanced security protocols in industries that handle digital assets to stay on top of digital threats. With the emergence of Elusive Comet, the threat landscape continues to evolve, and adversaries are increasingly adopting innovative approaches to bypass traditional defences, a reminder that the threat landscape is constantly changing and that adversaries are continuously evolving. The threat actors behind Elusive Comet have invested considerable resources into establishing a convincing online persona to maintain an appearance of legitimacy. 

To reinforce their facade of authenticity, they operate credible websites and maintain active social media profiles. As one example of the fraudulent entities that are associated with the group, Aureon Capital, a fake venture capital company posing as a legitimate company, Aureon Press, and The OnChain Podcast have all been carefully designed to trick unsuspecting individuals and businesses. 

The attackers usually contact users by sending them direct messages via X (formerly Twitter), or by contacting them via email, or by offering invitations to appear on their fabricated podcast as a guest. In the study, researchers found that after initiating contact and establishing a certain level of trust, attackers then move swiftly to set up a Zoom meeting under the pretext of learning more about the target's professional activities. 

It is common for key meeting details to be withheld until very near the time of the scheduled meeting, a tactic employed by the organisation to create an impression of urgency and encourage compliance among participants. A common occurrence is that victims are often asked to share their screens during the call so that they can demonstrate their work, and in doing so, they unknowingly expose their sensitive systems and data to the attackers. As a result of the Elusive Comet operation, Jake Gallen, CEO of the cryptocurrency company Emblem Vault, lost over $100,000 of his digital assets, which included his company's cryptocurrency. As a result, he was targeted after agreeing to participate in a Zoom interview with someone who was posing as a media person. 

By manipulating Gallen during the session into granting remote access to his computer under the disguise of technical facilitation, the attacker succeeded in obtaining his permission to do so. The attackers were able to install a malicious payload, referred to by the attackers as "GOOPDATE," which allowed them to gain access to his cryptocurrency wallets and steal the funds that resulted from this attack. 

It is clear from this incident that cryptocurrencies are vulnerable, especially among executives and high-net-worth individuals who interact regularly with media outlets and investors, which makes them particularly susceptible to sophisticated social engineering schemes because of their high level of exposure to these media outlets. Additionally, the breach emphasises that professionals operating in high-value financial sectors should have heightened awareness of cybersecurity and adopt stricter digital hygiene policies. 

A leading cybersecurity research and advisory firm specialising in forensics and advanced persistent threats (APTS), Security Alliance, meticulously tracked and analysed the Elusive Comet campaign, a campaign that is highly likely to persist for many years to come. Security Alliance published a comprehensive report in March 2025 detailing the tactics, techniques, and procedures (TTPS) used by threat actors and presenting comprehensive insights into these tactics. In their research, the attackers were able to install malware on victims' systems based primarily on a combination of social engineering and using Zoom's remote control features to get their malicious code into the systems of their victims. 

Despite drawing parallels between the methods used to conduct this campaign and those of the notorious Lazarus Group of North Korea, Security Alliance exercised caution when attributions were made. It was noted in the research that the similarities in techniques and tools could indicate common origins or shared resources; however, the researchers stressed the difficulties associated with attribution in a cyber threat landscape where various actors tend to duplicate or repurpose the methodologies of each other. 

Taking into account the methods employed by the Elusive Comet campaign, cryptocurrency professionals are strongly advised to take a comprehensive and proactive security posture to reduce the risk of falling victim to the same types of sophisticated attacks again. First and foremost, companies and individuals should make sure that Zoom's remote control feature is disabled by default, and that it is only enabled when necessary by the organisation and the individual. This functionality can be significantly restricted by restricting the use of this feature, which reduces the chances of cybercriminals exploiting virtual engagements as well.

It is also important to exercise increased caution in responding to unsolicited meeting invitations. When invitations are sent by an unknown or unverified source, it is essential to verify the identity of the requester through independent channels. In order to increase account security in cryptocurrency-related platforms, including digital wallets and exchanges, it is imperative to implement multi-factor authentication (MFA) as a critical barrier. 

MFA serves as an additional layer of protection if credentials are compromised as well, providing an extra layer of defence. Further, it will be beneficial for organisations to deploy robust endpoint protection solutions as well as maintain all software, including communication platforms such as Zoom, consistently updated, to protect against the exploitation of known vulnerabilities. Additionally, regular cybersecurity education and training for employees, partners, and key stakeholders is also extremely important. 

An organisation can strengthen the security awareness of its teams through the development of a culture of security awareness, which will allow them to identify and resist threat actors' tactics, such as social engineering, phishing attacks, and other deceptive tactics. The Elusive Comet operation highlights a broader, more dangerous threat to the cryptocurrency industry as cybercriminals are increasingly manipulating trusted communication tools to launch highly targeted and covert attacks targeting the crypto market. 

There is a strong possibility that the attacker may have been part of the North Korean Lazarus Group, but an official attribution remains elusive, further illustrating the difficulty in identifying cyber threat actors, yet there are some clear lessons to be learned from this attack. 

As today's cybersecurity landscape becomes more volatile and more complex, it is more important than ever for organisations to maintain vigilance, implement rigorous security protocols, and continually adapt to emerging threats to survive. The adversaries are continually refining their tactics, so the only people who can successfully safeguard the assets and reputation of their organisations and businesses against evolving threats to their identity and reputation will be those who invest in resilient defence strategies.

Fake Zoom Download Sites Spreading BlackSuit Ransomware, Experts Warn

 

A new cyberattack campaign is targeting Zoom users by disguising ransomware as the popular video conferencing tool, according to Cybernews. Researchers from DFIR have uncovered a scheme by the BlackSuit ransomware gang, which uses deceptive websites to distribute malicious software.

Instead of downloading Zoom from the official site, unsuspecting users are being lured to fraudulent platforms that closely mimic the real thing. One such site, zoommanager[.]com, tricks users into installing malware. Once downloaded, the BlackSuit ransomware remains dormant for several days before launching its full attack.

The malware first scrapes and encrypts sensitive personal and financial data. Then, victims are presented with a ransom demand to regain access to their files.

BlackSuit has a history of targeting critical infrastructure, including schools, hospitals, law enforcement, and public service systems. The ransomware begins by downloading a malicious loader, which can bypass security tools and even disable Windows Defender.

Researchers found that the malware connects to a Steam Community page to fetch the next-stage server, downloading both the legitimate Zoom installer and malicious payload. It then injects itself into a MSBuild executable, staying inactive for eight days before initiating further actions.

On day nine, it executes Windows Commands to collect system data and deploys Cobalt Strike, a common hacker tool for lateral movement across networks. The malware also installs QDoor, allowing remote access through a domain controller. The final phase involves compressing and downloading key data before spreading the ransomware across all connected Windows systems. Victims’ files are locked with a password, and a ransom note is left behind.

Cybersecurity experts stress the importance of downloading software only from official sources. The genuine Zoom download page is located at zoom[.]us/download, which is significantly different from the deceptive site mentioned earlier.

"Zoom isn't nearly as popular with hackers now as it was a few years ago but given how widely used the service is, it's an easy way to target unsuspecting users online."

To protect against these kinds of attacks, users should remain vigilant about phishing tactics, use reputable antivirus software, and ensure it stays updated. Many modern antivirus tools now offer VPNs, password managers, and multi-device protection, adding extra layers of security.

"As well as making sure you're always downloading software from the correct source, make sure you are aware of common phishing techniques and tricks so you can recognize them when you see them."

It’s also recommended to manually navigate to software websites instead of clicking links in emails or search results, reducing the risk of accidentally landing on malicious clones.

Zoom Refutes Claims of AI Training on Calls Without Consent

 

Zoom has revised its terms of service following concerns that its artificial intelligence (AI) models were being trained on customer calls without consent, leading to a backlash. 

In response, the company clarified in a blog post that audio, video, and chats would not be utilized for AI purposes without proper consent. This move came after users noticed modifications to Zoom's terms of service in March, which raised worries about potential AI training.

The video conferencing platform took action to enhance transparency, asserting that it had introduced changes to address the concerns. 

In June, Zoom introduced AI-powered features, including the ability to summarize meetings without recording the entire session. These features were initially offered as a free trial.

However, experts raised concerns that the initial phrasing of the terms of service could grant Zoom access to more user data than necessary, including content from customer calls. 

Data protection specialist Robert Bateman expressed apprehension about the broad contractual provisions that granted considerable data usage freedom to the service provider.

Zoom later amended its terms to explicitly state that customer consent is required for using audio, video, or chat content to train their AI models. This alteration was made to ensure clarity and user awareness.

AI applications are software tools designed to perform intelligent tasks, often mimicking human behavior by learning from vast datasets. Concerns have arisen over the potential inclusion of personal, sensitive, or copyrighted material in the data used to train AI models.

Zoom, like other tech companies, has intensified its focus on AI products to keep up with the growing interest in the technology. The Open Rights Group, a digital privacy advocacy organization, cautioned against Zoom's approach of launching AI features as a free trial and encouraging customer participation, deeming it more alarming due to potential opacity in its privacy policy.

A spokesperson for Zoom reiterated that customers retain the choice to enable generative AI features and decide whether to share content with Zoom for product improvement. 

The company's Chief Product Officer, Smita Hashim, emphasized that account owners and administrators can opt to activate the features and that those who do so will undergo a transparent consent process for AI model training using customer content. Screenshots displayed warning messages for users joining meetings with AI tools, offering the option to consent or exit the meeting.

Zoom Boss Greg Tomb Fired ‘Without Cause’

Zoom, the video conferencing platform that many people use to work from home, has terminated the contract of its President, Greg Tomb. Tomb was in charge of sales and had been involved in the company's financial calls. But, Zoom has confirmed that it will not hire anyone else for the position, and Tomb's exit was not because of anything he did wrong, the company said. 

Tomb reported directly to Zoom's CEO, Eric Yuan, who founded the company in 2011 and is credited with making Zoom so popular during the pandemic. Millions of people worldwide used Zoom to keep in touch while staying home. 

In April 2020, the company boasted 300 million daily participants on its video calls, including virtual weddings and funerals. However, Zoom has struggled to keep up its success, just like many other tech companies, and had to lay off over a thousand employees earlier this year. 

Despite tripling its workforce during the pandemic, the company cut 15% of its staff because of a decrease in demand. Yuan has admitted that the company did not have enough time to analyze its teams and decide if they were working towards its goals. 

As companies look to cut costs during the economic downturn, Zoom may lose out to other services such as Google Meet, Microsoft Teams, and Slack. In response, Zoom is trying to diversify its offerings. 

It announced plans to add email and calendar features last year and launched a chatbot to help users with issues. Zoom is also developing Zoom Spots, which are virtual co-working spaces that allow hybrid teams to work together. 

In an email to employees, the CEO wrote, "As the CEO and founder of Zoom, I am accountable for these mistakes and the actions we take today. To that end, I am reducing my salary for the coming fiscal year by 98 percent and foregoing my FY23 corporate bonus. Members of my executive leadership team will reduce their base salaries by 20 percent for the coming fiscal year while also forfeiting their FY23 corporate bonuses." 

Zoom became famous because it helped people stay connected while working from home during the pandemic. However, it's been tough for Zoom to keep up with its success, and they had to lay off staff. They're also facing tough competition from other video conferencing services like Google Meet, Microsoft Teams, and Slack.

Zoom is trying to offer new services like email and calendar features and virtual co-working spaces to attract customers. It's still unclear if Zoom can compete in the crowded video conferencing market. 

Cybercriminals Use Google Ads to Deploy Malware

 

Hackers are utilizing the Google Ads service more consistently than ever before to transmit malware. As soon as the victims click the download link on the threat actors' fake versions of the official websites, trojanized software is distributed. 

Grammarly, MSI Afterburner, Slack, Dashlane, Malwarebytes, Audacity, Torrent, OBS, Ring, AnyDesk, Libre Office, Teamviewer, Thunderbird, and Brave are some of the companies impersonated in these operations.

Raccoon Stealer, a modified variant of Vidar Stealer, and the IcedID loader are two examples of malware propagating to victims' systems. As a result, anyone looking for reliable software on a site with no active ad blocker will see commercials first and be more inclined to click on them because they closely resemble the search result.

Threat actors use a method in that phase to get beyond Google's automatic checks. If Google determines that the launch site is malicious, the operation is blocked and the advertisements are withdrawn. The trick, according to Guardio and Trend Micro, is to send users who click on the advertisement to a malicious site imitating the software project from a relevant but innocuous site made by the threat actor.

Vermux, a threat group, was discovered employing a significant number of masquerAds websites and domains, mainly operating out of Russia, to target GPUs and cryptocurrency wallets owned by Americans.

According to the researchers, in October they came across a malvertising operation where hackers, identified as DEV-0569, utilized Google Ads to send consumers to a malicious file download page. Microsoft claimed that it informed Google about the traffic distribution network abuse.

As per Microsoft, the techniques enable the group to reach more people and increase the number of victims. From August through October, Microsoft observed the threat actor distributing the BATLOADER malware using phishing emails that seemed to be genuine installers for various programs, including TeamViewer, Adobe Flash Player, Zoom, and AnyDesk. 

Use the necessary safety protocols such as an ad-blocker on your browser to block these campaigns by prohibiting Google Search sponsored results from appearing. Users should scroll down until they find the desired software project's official domain. Furthermore, a suspicious installer's unusually large file size is a red flag.  

Zoom Outage Rendered Services Unavailable

 

As per the latest updates, Zoom was down and unavailable for users worldwide and was preventing them from signing in or attending any meeting or webinar through it. 
 
People complained that they were unable to start or join any meetings and some also added that they were unable to manage their zoom services on websites. 

The users also mentioned that they were getting error pages displayed with text like “Sorry the page you are looking for is currently unavailable. Please try again later” “If you are the system administrator of this resource then you should check the error log for details, faithfully yours, Nginx.”

Zoom played a crucial role during the pandemic in recent years when the importance of cloud-based software, apps, and online activities was truly valued. During the global pandemic, people were stuck inside their homes and were forced to work, study, or communicate with family through screens. The application came as a savior, helping some people in being employed, and some in learning. 

During the investigation, the reports by Downdetector stated that the breakdown of Zoom was affecting numerous users worldwide. It was also noticed that early reports were majorly from the East coast of the US and the southern UK. 

The company itself verified and posted about the issue mentioned by the users on zoom’s service status page. The issue was figured out at 6:50 a.m., as per the reports. Zoom also kept updating throughout its investigation as it posted “we have identified the issue starting and joining meetings. We will continue to investigate and provide updates as we have them.” 

Zoom is a cloud-based platform allowing people to connect with each other worldwide through video conferencing or communication through collaboration. It provides virtual meetings by either audio or video or both modes. The app works on mobile, desktops, and laptops. 
 
The people facing the issue in zoom services let out a sigh of relief when the video conferencing company posted about the fixing of unavailable services on its status page on the 15th of September. “Everything should be working properly now! We are continuing to monitor the situation.” The CEO of Zoom tweeted, putting forth an apology for the disruption of the zoom services.

Two Critical Zero-Day Bugs Identified in Zoom Users and MMR Servers

 

Two critical bugs in videoconferencing app 'Zoom' could have led to remote exploitation in users and MMR servers. Natalie Silvanovich of Google's Project Zero bug-hunting team on Tuesday released an analysis of the security bugs; the vulnerabilities were uncovered as part of an investigation after a zero-click attack was demonstrated at Pwn2Own.

The researcher spotted two different flaws, a buffer overflow issue that impacted both Zoom users and Zoom Multimedia Routers (MMRs), and the second one transmits audio and video content between clients in on-premise deployments. Additionally, the platform possessed a lack of Address Space Layout Randomization (ALSR), a security mechanism that helps to guard against memory corruption assaults.

"In the past, I hadn't prioritized reviewing Zoom because I believed that any attack against a Zoom client would require multiple clicks from a user," the researcher explained in a blog post. "That said, it's likely not that difficult for a dedicated attacker to convince a target to join a Zoom call even if it takes multiple clicks, and the way some organizations use Zoom presents interesting attack scenarios."

"ASLR is arguably the most important mitigation in preventing exploitation of memory corruption, and most other mitigations rely on it on some level to be effective," Silvanovich noted. "There is no good reason for it to be disabled in the vast majority of software." 

As MMR servers process call content including audio and video, the researcher says that the bugs are "especially concerning" – and with compromise, any virtual meeting without end-to-end encryption enabled would have been exposed to eavesdropping, 

As per recent reports, the vulnerabilities were reported to the vendor and patched on November 24, 2021, and Zoom has since enabled ASLR. While most video conferencing systems use open-source libraries such as WebRTC or PJSIP for implementing multimedia communications, Project Zero called out Zoom's use of proprietary formats and protocols as well as its high licensing fees (nearly $1,500) as barriers to security research.

"These barriers to security research likely mean that Zoom is not investigated as often as it could be, potentially leading to simple bugs going undiscovered," Silvanovich said. "Closed-source software presents unique security challenges, and Zoom could do more to make their platform accessible to security researchers and others who wish to evaluate it." 

Last year in November, Zoom rolled out automatic updates for the software's desktop customers on Windows and macOS, as well as on mobile. Previously, this feature was only accessible to business users.

Zoom Security Flaw: Now Hackers Can Take Control Of Your PC, Wait For Patch

 


Zoom security issues were lately troubling users worldwide, very often so. The Zoom video conferencing app was not in the limelight before the ongoing pandemic, however, since the inception of Covid-19, a lot has changed along with the ways of living, this was also the time when Zoom App underwent some regulatory security measures, owing to the suddenly enhanced reputation enjoyed by the app, as the work from home was necessitated by the pandemic. 

However, as of now, it is being observed that the security measures that had been taken a year ago are failing to secure users' data from threat actors.

Cybercriminals exploited a vulnerability and undertook a distant code execution (RCE) assault to take management of host PCs. The two Computest cyber safety intelligence observed the vulnerability on the Pwn2Own 2021 competition, organized by the Zero Day Initiative. The two Computest researchers Daan Keuter and Thijs Alkemade were awarded $200,000 for their findings. 

How does This work? 


Foremostly, the hacker has to be a part of the same organizational domain as the host PC’s user has to get permission from the host to join the meeting; When the attackers become part of a meeting, they will be able to execute a chain of three malware that will install an RCE backdoor on the victim’s PC. 

It can also be understood as — the threat actors can get access to your PC, and simultaneously will able to be able to implement remote commands that will then give access to your sensitive data.

Besides, what is even dangerous here is that the hackers can run their operations without the victim being required to do anything, therefore it is very essential to add more layers of security measures that can slow down the future operations of the attackers. 

The aforementioned operation runs on Mac, Windows, but on Zoom’s iOS and Android apps, it has not been checked yet. Notably, the browser version is safe. 

Currently, Zoom is yet to take measures, and the technical details of the attack have not been reported to the public, yet. Reportedly, the patch will arrive on Zoom for Mac and Windows within the next 90 days.
