	ARRL IT Security Incident - Report to Members



	Sometime in early May 2024, ARRL’s systems network was compromised by threat actors (TAs) using information they had purchased on the dark web. The TAs accessed headquarters on-site systems and most cloud-based systems. They used a wide variety of payloads affecting everything from desktops and laptops to Windows-based and Linux-based servers. Despite the wide variety of target configurations, the TAs seemed to have a payload that would host and execute encryption or deletion of network-based IT assets, as well as launch demands for a ransom payment, for every system.

	This serious incident was an act of organized crime. The highly coordinated and executed attack took place during the early morning hours of May 15. That morning, as staff arrived, it was immediately apparent that ARRL had become the victim of an extensive and sophisticated ransomware attack. The FBI categorized the attack as “unique” as they had not seen this level of sophistication among the

	Parks on the Air announces the new Facebook mode

	McMurdo Station, Antarctica: Parks on the Air will now be accepting QSOs conducted entirely on Facebook. Special awards will be issued for QSOs at 25, 50, and 75 likes, and a monthly for the QSO with the most comments complaining about how bad operators are ruining the airwaves.

	Jason Johnston (W3AAX), administrator of the Facebook POTA group and owner of the program says it was inevitable.

	"People were doing traditional QSOs on the air and then coming to Facebook to correct their logs so we kinda wondered what the point of using our radios was. Now more people can get out to their local park, open the Facebook app, and make some QSOs" Johnston said.
