A new AI-powered ransomware variant codenamed PromptLock has been discovered by Slovak cybersecurity company ESET, which leverages the power of large language models to generate malicious Lua scripts. This marks a significant milestone in the evolution of cyber attacks and highlights the growing capabilities of AI in the hands of cybercriminals.
The first AI-powered ransomware using OpenAI's gpt-oss:20b model has been discovered, marking a significant milestone in cyber attacks. PromptLock, the newly discovered AI-powered ransomware, leverages large language models to generate malicious Lua scripts that can enumerate local filesystems and encrypt files. The use of prompt injection attacks allows attackers to bypass safety filters and exploit vulnerabilities in AI models, potentially causing data exfiltration, code execution, and other malicious activities. Threat actors have used large language models like Claude AI chatbot to commit large-scale theft and extortion of personal data. The emergence of prompt injection attacks highlights the need for improved safety research in AI models to prevent exploitation.
In a world where artificial intelligence (AI) has become an integral part of our daily lives, a new and menacing threat has emerged in the realm of cybersecurity. The creation of the first AI-powered ransomware using OpenAI's gpt-oss:20b model marks a significant milestone in the evolution of cyber attacks. According to recent reports, the Slovak cybersecurity company ESET has discovered an AI-powered ransomware variant codenamed PromptLock, which leverages the power of large language models to generate malicious Lua scripts that can enumerate local filesystems, inspect target files, exfiltrate data, and encrypt them.
The emergence of PromptLock is a testament to the growing capabilities of AI in the hands of cybercriminals. By utilizing the gpt-oss:20b model, which was released by OpenAI earlier this month, the attackers can generate Lua scripts that are cross-platform compatible, functioning on Windows, Linux, and macOS. This level of sophistication poses significant challenges for threat detection and makes it increasingly difficult for defenders to identify and mitigate the attacks.
The prompt injection attack vector has become a new avenue for cybercriminals to exploit AI models. By leveraging this technique, attackers can bypass safety filters and produce unintended results, causing AIs to delete files, steal data, or make financial transactions. Moreover, recent research has uncovered an attack called PROMISQROUTE that abuses ChatGPT's model routing mechanism to trigger a downgrade and cause the prompt to be sent to an older, less secure model.
The development of PromptLock is also linked to the emergence of large language models (LLMs) powering various chatbots and AI-focused developer tools. These LLMs have been found susceptible to prompt injection attacks, potentially allowing information disclosure, data exfiltration, and code execution. As Anthropic revealed earlier today, two different threat actors that used its Claude AI chatbot committed large-scale theft and extortion of personal data targeting at least 17 distinct organizations.
The growth in the capabilities of AI-powered malware is a worrying trend for cybersecurity experts. As AI becomes more prevalent in various sectors, it is essential to develop robust security measures to counter these emerging threats. In this context, ESET's discovery of PromptLock serves as a stark reminder of the complexity and evolving nature of the security challenge.
Furthermore, the emergence of prompt injection attacks highlights the need for improved safety research in AI models. As Adversa AI pointed out in its recent report, adding phrases like 'use compatibility mode' or 'fast response needed' can bypass millions of dollars in AI safety research, making these LLMs more susceptible to exploitation.
In conclusion, the creation of PromptLock marks a significant milestone in the evolution of cyber attacks. As we move forward in this new era of cybersecurity threats, it is essential to develop robust security measures and improve safety research in AI models to counter these emerging threats.
