The Pumakit Linux rootkit employs advanced stealth techniques to evade detection. It uses a staged deployment, activating only under specific conditions, such as secure boot checks. The rootkit embeds necessary files as ELF binaries within the dropper, enhancing its ability to persist and remain undetected. This sophisticated malware poses a severe risk to Linux systems, indicating a high level of development and a need for enhanced endpoint security solutions.

Microsoft’s new AI feature ‘Recall’ for Copilot+ PCs stores screenshots of sensitive data, including credit cards and social security numbers, even when a ‘sensitive information’ filter is enabled. This has raised serious privacy and security concerns among users. This feature takes continuous screenshots of everything a user does. The data is stored locally but sent off to Microsoft’s LLM for analysis. This has prompted an investigation by the UK Information Commissioner’s Office. This incident highlights the potential risks of AI-powered surveillance features and the importance of user privacy.
