The **3CX supply chain attack (2023)** compromised software used by **600,000 organizations globally**, including major enterprises like American Express and Mercedes-Benz. Attackers infiltrated 3CX’s update mechanism, distributing a trojanized version of its desktop app that installed malware on end-user systems. The attack leveraged **polymorphic malware**, making detection difficult via traditional signature-based tools. The breach enabled data exfiltration, lateral movement within corporate networks, and potential follow-on attacks, including credential theft and ransomware deployment. While not explicitly AI-generated, the attack exhibited **AI-like characteristics**—unique payloads per victim, evasion of sandboxing, and delayed activation—highlighting vulnerabilities in software supply chains. The incident resulted in **operational disruptions**, **reputational damage**, and **financial losses** across affected organizations, with some victims reporting **fraudulent transactions** and **compromised internal systems**. The prolonged detection timeline (aligned with IBM’s 2025 report average of **276 days**) exacerbated the impact, as attackers maintained persistence in breached environments.
