Cybercriminals use paid search ads to lure users searching for IT tools to harmful websites. A new malvertising campaign targets tools like AnyDesk and Cisco AnyConnect VPN. Prevention is key: We will show you how to protect your company from trojanized installers and ransomware.
Cybercriminals use paid search ads to lure users searching for IT tools to harmful websites. A new malvertising campaign targets tools like AnyDesk and Cisco AnyConnect VPN. Prevention is key: We will show you how to protect your company from trojanized installers and ransomware.
The attack vectors are becoming more subtle. In July, a new malvertising campaign was observed that specifically uses ads in Google and Bing search to target users looking for legitimate IT tools. The focus is on applications such as AnyDesk, Cisco AnyConnect VPN, and WinSCP. The goal is to entice users to download trojanized installers to penetrate corporate networks and prepare for follow-on damage, such as ransomware attacks. This 'opportunistic' activity, referred to as Nitrogen, uses paid advertising to spread malware such as BATLOADER and IcedID. This underscores the need for a holistic prevention strategy that considers not only technical vulnerabilities but also human behavior.

The Anatomy of the Threat
The anatomy of this threat follows a complex infection chain. The Nitrogen campaign, first documented in June 2023, redirects users to compromised WordPress sites, where malicious ISO image files are hosted. This culminates in the deployment of Python scripts and Cobalt Strike beacons on the target system.
A similar attack sequence uncovered by Trend Micro involved a fraudulent WinSCP application serving as a springboard for a BlackCat ransomware attack. This tactic illustrates how quickly cybercriminals adapt their methods.
The solution lies in consistent employee training (Cybersecurity Awareness) and the implementation of systems for proactive detection of malicious activities before they lead to a breach. Only prevention can be the solution here.
