At 12:29 in the podcast, there’s info about a specific encrypted German Police message - transmitted in #Morsecode during #WWII - which was intercepted by the #ChicksandsPriory #Ystation - then forwarded to #BletchleyPark for decryption - through which the Allies heard ( for the 1st time through #SIGINT ) about horrific mass killings of Jews that were happening across Europe at the time. #RAFChicksands #ChicksandsRAFB #Chicksands #WWIIhistory #MilitaryIntelligence #SignalsIntelligence #Holocaust

My network is getting hammered by SSH scanners lately. Possibly checking for CVE-2023-25136. The IP below has sent over 2k flows in a day and Greynoise tags it as an SSH Bruteforcer and worm.
Another IP originating from Russia (92.63.197[.]82) has also sent just over 2k flows. Historical analysis shows it targeting previous SSH vulnerabilities.

Tools I can't go without: Augury, Maxmind, @DomainTools , Censys
