Browser-based ransomware: the new AI threat

Artificial intelligence has transformed countless sectors, but it has also opened new doors to digital threats. Recently, cybersecurity researchers have detected that models like DeepSeek, with fewer security restrictions, can generate ransomware that operates exclusively in the browser, without needing to install malicious software on the device. This approach, which leverages Chrome's File System Access API, allows attackers to encrypt local files through social engineering, simply by tricking the user into clicking a button. Although the sample found was incomplete, experts warn that with little effort it could become a real threat, and attempts by malicious actors using simple prompts in these LLMs have already been observed. For businesses, this underscores the urgency of strengthening cybersecurity with strategies that cover both the traditional perimeter and new browser-based vectors.

At Q2BSTUDIO, we understand that protection against emerging threats requires a comprehensive approach. Therefore, we offer specialized services in cybersecurity and pentesting to identify vulnerabilities before they are exploited. Additionally, we combine this security with the development of custom applications and custom software that integrate robust controls from the design phase. Artificial intelligence, when implemented responsibly, can be an ally: our AI agents help monitor anomalous behaviors in real time, and our AI solutions for businesses enable automated incident responses. Likewise, our AWS and Azure cloud services ensure scalable yet secure infrastructures, and our business intelligence services with Power BI provide visibility into operational risks. In a scenario where any AI model can generate malicious code, having a technology partner that understands these dynamics is key to maintaining business continuity.
