Spotify's ads crossed from nuisance over to outright nasty this week, after the music service’s advertising started serving up malware to users on Wednesday. The malware was able to automatically launch browser tabs on Windows and Mac PCs, according to complaints that surfaced online.
As is typical for this kind of malware, the ads directed users’ browsers to other malware-containing sites in the hopes that someone would be duped into downloading more malicious software. The “malvertising” attack didn’t last long as Spotify was able to quickly correct the problem.
“We’ve identified an issue where a small number of users were experiencing a problem with questionable website pop-ups in their default browsers as a result of an isolated issue with an ad on our Free tier,” Spotify said on several threads in its support forums. “We have now identified the source of the problem and have shut it down. We will continue to monitor the situation.”
