If you’re a dedicated player of Duet Night Abyss, you might be wondering why your PC’s antivirus blew up following the game’s latest update a couple of nights ago. And if your antivirus didn’t blow up… then maybe it’s time for a scan. The developers have confirmed that the game’s launcher was hacked to deliver keylogger spyware.
On March 18th, players on a Duet Night Abyss subreddit posted Windows Defender logs showing that the “Umbral Stealer” trojan had been detected following the game’s latest update. Developers confirmed the “malicious attack,” posting a log of their initial alerts and the resolution, as well as mitigation steps going forward.
At the end of the statement, the development team said that the game would be sending out “Commission Manual: Volume III*5, Prismatic Hourglass*10,” which Kotaku reports is equivalent to 10 random skins for the characters. Which is nice, I suppose, but won’t be much comfort to someone who’s had their identity stolen because a keylogger got their bank account login credentials.
Duet Night Abyss is a free-to-play gacha game in the same vein as Genshin Impact, available on Windows, Android, and iOS. I hadn’t heard of it before now, but apparently it’s racked up a million registrations since launching late last year. And apparently this isn’t the first time it’s been hacked. A hacker apparently got into the update system a few weeks ago and issued a far less malicious attack, simply alerting users to the developer Pan Games’ outdated security systems, along with a few more editorial comments.
Duet Night Abyss is available to download and play via Steam, but the attack appears to have targeted the game’s standalone updater and launcher. Still, Steam itself has become an increasingly juicy target where PC gamers log in and download games by the millions. Free-to-play and early access games are apparently the most likely to be infected.
