Hello.

Using chatbots for medical advice could elicit hallucinations and even expose you to security and privacy risks. Here’s what’s at stake and how to stay safe. For better or worse, chatbots are changing the way we think, learn and perceive the world around us. This kind of disruption is manifest in many areas of life, but perhaps one of the most sensitive and often concerning is the growing use of generative AI (GenAI) tools for healthcare. Alongside a number of freely availabl

The malware pairs remote access capabilities with ready-made campaign tools, lowering the barrier for full device compromise Our recent review of threat detections in Brazil surfaced BTMOB, an Android remote access trojan (RAT) that is less notable for detection volume than for the damage it can wreak. The combination of phishing-led delivery, ready-made app-building tooling and device takeover capabilities makes BTMOB a threat to watch well beyond Brazil or Latin America. BT

Many had become used to China and Russia's often belligerent tone, flexing t

Conflict is a boon for opportunistic fraudsters. Look out for their ploys. It didn’t take long for tensions in the Middle East to spill over into the cyber domain. There’s been significant disruption of a major US medtech provider, the compromise of OT assets in US critical infrastructure, and ongoing ransomware attacks on businesses by Iran-nexus groups. But what about regular internet users? The truth is that geopolitical tension and conflict offers potentially rich picking

The difference this time round is that they’re not just more stylish – and arguably harder to tell from regular
