Researchers from IMDEA Networks, in collaboration with Universidad Carlos III de Madrid, IMDEA Software Institute, and the University of Calgary, have conducted the first large-scale study—"Your Signal, Their Data: An Empirical Privacy Analysis of Wireless-scanning SDKs in Android"—on how certain Android mobile applications use a device's WiFi and Bluetooth connections to track users' movements in their daily lives, thereby violating their privacy.

Firstly, welcome - you have found us.

Secondly, the origin story - https://www.reddit.com/r/blueteamsec/comments/1mc3pza/reddit_managed_to_ban_the_mod_of_rblueteamsec_due/ of which the tl;dr is we were in /r/Blueteamsec since 2018 and then in July 2025 the mod account got banned.

Thirdly, settle in as this is going to be the permanent home. The only features missing from Lemmy really are:

• the titles are a little shorter than we are used to
• the ability to style some of the community
• categories

but in short nothing material. The Jerboa mobile client is excellent.

Fourthly, how does this work? Broadly speaking

• there are optimised sources across X, various sites, groups and lists etc.
• they are reviewed generally once or twice a day (start / end)
• content is ideally < 1 week old at time of posting
• content is then reviewed / curated / titles edited and posted

• link to the source where possible i.e. not a news article but the technical source
• cyber security relevant and insightful to cyber defence across technology, adversarial tradecraft/techniques/tools, threat intelligence, policy or events

Finally, all community contributions welcome!

Cyber threats are becoming more frequent and sophisticated, and rural hospitals and clinics are feeling the pressure from all sides: tight budgets, small teams, limited training, complex technology, and vendors that do not always offer much help. Often, they are left juggling security tools without the IT support to use them effectively, according to Paubox. Compared to their urban counterparts, rural healthcare organizations are hitting more cybersecurity roadblocks, and not just in one or two … More → The post Why rural hospitals are losing the cybersecurity battle appeared first on Help Net Security.
