A malvertising campaign is targeting corporate users who are interested in downloading Cisco’s Webex software. Threat actors are purchasing ad space from Google and impersonating Cisco in order to distribute malware to unsuspecting users. Although Webex itself has not been compromised, the campaign aims to trick users into clicking on a seemingly genuine advertisement that actually contains the BatLoader first-stage malware threat.
BatLoader is a malware that is capable of downloading additional payloads on a compromised computer. It is specifically designed to evade detection and is part of the infection chain used to perform the initial compromise. The malware is skilled at bypassing traditional antivirus tools, making it difficult for organizations to detect and mitigate.
The malicious advertisement takes advantage of a loophole in Google Ads’ policy for display URLs. It exploits a tracking template to serve as a filtering and redirection mechanism. This allows the threat actors to deliver the malware to their intended targets without raising suspicion.
It appears that the threat actors behind this campaign are primarily interested in targeting corporate users. By using sophisticated malware that can bypass traditional antivirus measures, they hope to infiltrate organizations and carry out malicious activities undetected. To protect against such attacks, researchers at Malwarebytes Labs recommend implementing a more comprehensive solution such as endpoint detection and response (EDR), coupled with a managed detection and response (MDR) service. This combination would involve using advanced technologies to detect and respond to threats, as well as human analysts who can review and investigate suspicious activities.
The researchers at Malwarebytes Labs who uncovered the campaign have alerted Google about the false advertising incident. It is crucial for digital platforms like Google to be aware of such malvertising campaigns and take action to prevent their users from falling victim to these attacks.
As the threat landscape continues to evolve, organizations and individuals alike must remain vigilant and take proactive measures to protect their systems and data. Keeping up with the latest cybersecurity threats and trends is essential in order to stay one step ahead of threat actors. Subscribing to reputable cybersecurity newsletters can provide valuable information and insights on emerging threats, newly-discovered vulnerabilities, data breaches, and best practices for maintaining a secure digital environment.
In conclusion, threat actors are exploiting Google Ads to impersonate Cisco and distribute malware to corporate users interested in downloading Webex. The malvertising campaign uses the BatLoader malware to compromise systems and evade traditional antivirus measures. Organizations should consider implementing advanced detection and response solutions in combination with human analysts to enhance their security posture and mitigate the risk of falling victim to such attacks. Awareness and staying informed about the latest cybersecurity threats are crucial in maintaining a secure digital environment.
