- ‘Proactive SIM’ cards can hijack smartphones, IoT devices and even EV chargers
August 18, 2026
A malicious SIM card can instruct the device it sits in to run commands of an attacker’s choosing, and on the cellular modules embedded in electric vehicle chargers, industrial routers, and car telematics units, essentially allowing it to take the entire device over. Researchers from the University of Birmingham and the German security firm Fuzzware demonstrated ...
- Mitigating large-scale credential attacks
August 18, 2026
Identity has effectively become the new perimeter, where cybercriminals are increasingly choosing to log in rather than break in. To accomplish this, attackers frequently gather previously leaked username and password pairs. Gathering these credentials can then allow them to pivot to password spraying against services exposed to the internet, gaining credentials for other products and ...

- ChainDrop worm crawls into npm supply chain, evades standard defenses
August 15, 2026
A new variant of the Shai-Hulud npm worm has poisoned hundreds of packages while adding propagation techniques that can leave little trace in the corresponding source repositories. In Frank Herbert’s Dune, Shai-Hulud was the name of the giant self-sustaining desert sandworms that moved silently beneath the surface of the planet Arrakis. So it made sense that when ...

August 14, 2026
Microsoft has recently fixed a vulnerability that allowed threat actors to bypass advanced security measures, disable antivirus software, and expose the target device to full system takeover. All of this, it seems, could have been possible with a very simple script, and a single click from the victim’s side. Luckily, the vulnerability was discovered by white hat hackers, ...
