A German startup wants to use IoT sensors and a wireless-mesh network to detect forest fires within 10 minutes to an hour of when they start as opposed to the hours or even days it can take using current methods based on thermal imaging, satellite surveillance and human smoke spotters. Dryad Networks is developing sensors to detect gases associated with forest fires and engineering how to network them using LoRaWAN and other wireless technologies so…

Cisco Blogs / Security / Threat Research / Nibiru ransomware variant decryptor Nikhil Hegde developed this tool. Weak encryption The Nibiru ransomware is a .NET-based malware family. It traverses directories in the local disks, encrypts files with Rijndael-256 and gives them a .Nibiru extension. Rijndael-256 is a secure encryption algorithm. However, Nibiru uses a hard-coded string “Nibiru” to compute the 32-byte key and 16-byte IV values. The decryptor program leverages this weakness to decrypt files…

I love it when data surprises me. In cybersecurity, we’re good at researching how things can go wrong, but it’s harder to figure out when things are going right. Most of our prescriptive advice starts to sound obvious after all these years: least privilege. Patch all the things. Segmentation. Redundancy. Resilience. And always, always, encryption. But which practices actually lead to a successful security program? This year we decided to take a new strategy, with…

The COVID-19 pandemic set a new high bar for organizations and their need for increased business resiliency.
