A massive attack on the Microsoft Exchange Server opened another chapter in the current global cybersecurity crisis in March 2021. According to Microsoft, only on-premise environments have been invaded; the online version of the Exchange Server is not vulnerable. The Microsoft Threat Intelligence Center (MSTIC) attributes this attack to HAFNIUM, a group sponsored by the Chinese state. This is the second massive cyberattack incident in less than four months. At the end of 2020, one of the most complex and longest-running attacks came to the fore; its initial target was the Orion platform, developed by SolarWinds. The invasions ended up compromising the systems of several U.S. state government agencies and private companies.
A German startup, Dryad Networks, is proposing a solution to help detect forest fires. Silvanet can be considered an Internet of Trees and is composed of a network of sensors powered by solar energy and connected in a wireless mesh, operating as an early warning system to identify forest fires. The idea of an IoT (Internet of Things) network connected to the natural world was conceived by the founders of Dryad Networks when large fires devastated the Amazon rainforest in 2019. The team successfully tested a minimum viable product in a German forest in May 2020.
According to a Reuters report in February 2021, Chinese hackers also hacked US government computers in 2020. The security breach exploited, also in SolarWinds software, was named Supernova and apparently has no connection to the one that has allowed hackers infiltrate the company's update build process. Chinese hackers have exploited this vulnerability only after hacking into a network by some other means. Then they used the failure to go deeper. SolarWinds fixed the vulnerability in December.
