AI-created ransomware and NFC attacks lead the surge in new cyberattacks - here's how you can stay safe this holidays (www.techradar.com)

ESET has unveiled PromptLock, the first AI-driven ransomware capable of dynamically generating malicious scripts using an OpenAI model through the Ollama API. This innovative ransomware can autonomously scan victim systems and decide whether to exfiltrate, encrypt, or delete data, leveraging a dual-component structure that includes a main static module for server communication and cross-platform Lua scripts created on-the-fly. Although currently a proof-of-concept, the emergence of PromptLock indicates a significant shift in cyber threats, as it lowers the barrier for launching sophisticated attacks, making it easier for less-skilled individuals to deploy complex malware. In addition to this groundbreaking ransomware, ESET also reported a rise in NFC malware, with an 87% increase in related telemetry in the latter half of the year. This surge signifies the growing sophistication of mobile threats. In response to these developments, cybersecurity experts recommend users and organizations remain vigilant by keeping software updated, employing robust endpoint protection, exercising caution with unfamiliar files, and backing up data regularly. As AI tools enhance the capabilities of cybercriminals, implementing foundational cybersecurity measures becomes increasingly critical for safeguarding sensitive information.
