According to researchers, hackers have been exploiting vulnerabilities in a popular print management software, PaperCut, to deploy Clop ransomware on victims’ networks. The flaw allows threat actors to bypass security measures and gain access to the target’s network, allowing them to infect machines with ransomware.

Why it matters: The Clop ransomware group has been one of the most active and successful ransomware groups over the past year, and they continue to evolve their tactics to compromise high-value targets. This attack shows that even relatively low-level vulnerabilities can be exploited to deliver ransomware payloads, emphasizing the need for organizations to remain vigilant and address all vulnerabilities in a timely manner.

• This breach highlights the ongoing trend of attackers exploiting weaknesses in third-party software and tools that may not receive as much attention as popular software products.

• Print and document management systems can serve as a potential entry point for attackers to access a target’s network.

• The use of common software and hardware systems in many organizations makes them vulnerable to attacks, highlighting the need for a comprehensive security strategy that addresses potential vulnerabilities.
