Lessons Learned From 'AdFection' and What To Do Next

Last week, researchers at Citizen Lab revealed a horrifying new malware campaign, dubbed “AdFection.” It used an ad network to distribute spyware to journalist’s devices to infect them without the target ever needing to click anything. This sort of attack on journalists is dangerous and incredibly concerning, especially since it’s built on the backbone of a technology we already object to: behavioral advertising. Although this type of attack has only been described targeting journalists, you can take a few steps we outline in the next section to mitigate the risk no matter who you are. A few factors combined to make this attack a noteworthy first-of-its-kind. First, it utilized the surveillance ad-tech ecosystem to specially target the malicious code. Second, the spyware it delivered was so-called “zero-click,” meaning it required no interaction from the user to be infected: all that is required is for the ad to be delivered and code bundled along with it to be run, which happens autom
