In March 2025, DeepSeek users were targeted by cybercriminals through fake sponsored Google ads resulting in the distribution of malware. These ads led to a fabricated DeepSeek website where a download button, upon being clicked, delivered a Trojan to the user's system. The malware identified as Malware.AI.1323738514, was part of a scheme where criminals outbid legitimate brands and bypassed Google's controls. The issue extended beyond the direct impact on users, as it raised questions about data collection practices. Concerns from Italy's Data Protection Authority led to DeepSeek's app removal from app stores. Separately, Texas banned DeepSeek and other Chinese-owned apps from state devices, citing security reasons.
