Microsoft to the rescue of XP Users to combat WannaCrypt - Microsoft has taken the unprecedented step of issuing patches for unsupported operating systems - like Windows XP - in the wake of the massive WannaCrypt ransomware attacks against organisations across the globe.
Businesses, governments and individuals in 74 countries across the globe have been victims of more than 45,000 attacks by this one strain of ransomware in the space of just a few hours. Wannacrypt ransomware demands $300 in Bitcoin for unlocking encrypted files - a price which doubles after three days. Users are also threatened with having all their files permanently deleted if the ransom isn't paid in a week. Cybersecurity researchers have suggested the ransomware attacks are so potent because they exploit a known software flaw dubbed EternalBlue. This Windows flaw is one of many zero-days which apparently was known by the US National Security Agency (NSA) before being leaked by the Shadow Brokers hacking collective. Microsoft released a patch for the vulnerability earlier this year - but only for the most recent operating systems.
One thing many of the targets have in common is that they're running old Windows operating systems like Windows XP, Windows 8 and Windows Server 2003, which now only usually receive patches if the organisation using them are receiving special custom support. However, in order to ensure as many systems as possible are protected against WannaCrypt ransomware and other attacks, Microsoft has made security patches for Windows XP and other operating systems broadly available to download.

NVIS PROPAGATION - UNDERSTAND THE BASICS - Radio Communication via Near Vertical Incidence Skywave propagation can be used for communication over a wide area. It is very well suited for emergency communication. It uses frequencies between 3 and 10 MHz with amateur allocation in the 5 MHz particularly attractive. Two propagation researchers, Ben Witvliet and Rosa Ma Alsina-Pages wrote an interesting paper with lots of reference to other papers for additional reading.
