Baldr Malware: A Short-Lived Star or Info Stealer That Will Return?

The Baldr malware is a bit of an enigma. Appearing first in late 2018, researchers at Sophos have tracked it through four rapid revisions until suddenly, on May 31, 2019, the distributor (overdot) declared that further development and support had ceased. Users had been expecting the developer — thought to be LordOdin by Malwarebytes — to deliver a major upgrade to version 4.0.
