Ransomware attacks cripple a major US pipeline

I’m sure you have all most likely heard about a ransomware attack that has shutdown Colonial Pipeline, a major US fossil fuel pipeline that provides 45% of fuels to the US east coast which is causing gas prices to spike. The malware is suspected to be of Russian origins but is not suspected to be a state-sponsored attack and appears to be purely financially motived.

The hacker group calling themselves “DarkSide” claimed responsibility for the attack, but surprisingly they also issued an apology as well. They apologized for taking down a public utility and they will do research in the future to ensure that they don’t affect any critical infrastructure in future campaigns.

Gee thanks guys.

Ncap 1.30 Officially Released

The Nmap Project is pleased to release Npcap Version 1.30 at
https://npcap.org. We hope Nmap and Wireshark users will be especially
happy with the raw WiFi improvements, since you tend to be particularly
savvy about low-level network inspection. It turns out that some of the
issues we thought were caused by lower level hardware drivers were actually
bugs in our driver. Oops! But at least that means we can fix them
ourselves, and we did. This release also includes substantial performance
improvements, especially for applications which repeatedly call
pcap_findalldevs(). That has been a sore point in the past, so Dan Miller
went in and restructured the whole system for better performance. Wireshark
starts up noticeably faster. Memory allocations were also optimized by
replacing GlobalAlloc() calls with the modern HeapAlloc() system. You can
read about all the improvements in this and previous Npcap releases at
https://npcap.org/changelog.
