A huge cyberattack hit dozens of countries over the past week. British National Health Services were hit particularly hard, leaving healthcare workers without patient data, which forced hospitals to cancel procedures. The attack used “ransomware” to get into computers, encrypt data, and then forced people to pay up in untraceable currency before giving the files back. Basically, imagine someone breaking into your office, putting a lock on your file cabinet, and refusing to give you the key until you leave money next to the stump in that seedy park you never see any kids at during the day. The attack is still ongoing, but if you’ve updated your Windows system past XP (which NHS hadn’t,) you’re probably fine.
