Are Google Ads Putting Your Business at Risk for Ransomware Attacks?
As you search the internet, you likely click on a Google Ad either unknowingly or you feel confident Google is safe. However, recent reports suggest that these ads could be putting your business at risk for ransomware attacks.
Malicious actors are using Google Ads and SEO poisoning to promote popular software downloads, like Cisco AnyConnect and Citrix Workspace, that are loaded with the BumbleBee malware. This type of malware gives attackers initial access to your network and can result in devastating ransomware attacks. In this blog post, we'll discuss what you need to know to keep your business safe from these threats.
The BumbleBee Malware Loader: In April 2022, security professionals discovered BumbleBee, a malware loader that is used for gaining initial access to networks before conducting ransomware attacks. In September 2022, a new version of the malware was identified utilizing the PowerSploit framework for reflective DLL injection into memory. This new version is even stealthier than the original, making it harder to detect.
Google Ads and SEO Poisoning: One of the ways that attackers are delivering BumbleBee is through Google Ads and SEO poisoning. They create fake landing pages that promote trojanized software downloads, like Cisco AnyConnect, that enable them to install the malware onto unsuspecting users' computers. One example of this occurred in February 2023, when a fake Cisco AnyConnect Secure Mobility Client download page was promoted through a malicious Google ad.
The Trojanized MSI Installer: Once the user clicks on the fake download page, they are prompted to download a trojanized MSI installer that installs the BumbleBee malware. This trojanized MSI installer is deceptively named to avoid suspicion, and it is copied onto the user's computer along with a PowerShell script. The legitimate Cisco AnyConnect installer is also copied onto the user's computer to further disguise the attack.
The PowerShell Script: The PowerShell script conducts the malicious activity on the compromised device. It downloads additional malicious payloads and communicates with a control and command server that is controlled by the attackers. The attackers can then use the BumbleBee malware to gain access to your network and encrypt your files with ransomware.
Protecting Your Business: To protect your business from attacks like this, it is important to educate your employees on the dangers of downloading software from third-party websites. Encourage them to only download software directly from the vendor's website, and to always double-check the URL before clicking on any links. Additionally, consider using endpoint protection software that can detect and block malware before it can infect your devices.
Conclusion: Google Ads are extremely popular which often makes them appear on every top ranked front page of the majority of websites visited. Especially true if you’re using Google Chrome as your browser and Google Search. Be careful as these ads can also put your business at risk for ransomware attacks. Attackers are using SEO poisoning and fake landing pages to promote trojanized software downloads that contain the BumbleBee malware. To protect your business from these threats, it is important to educate your employees on safe browsing practices and to use endpoint protection software. Don't let Google Ads be the weak link in your cybersecurity chain. Stay vigilant and stay safe.
