KeRanger Mac Ransomware Based On Linux Forebear, Not Windows

An anonymous reader writes: It appears that the KeRanger ransomware that's been tormenting Mac users for the past days is actually based on a ransomware variant that targets Linux servers, and not on a ransomware family coming from Windows. That particular Linux ransomware is also based on an open-source ransomware called Hidden Tear that was uploaded to GitHub by a Turkish security researcher. So obviously, the conclusion is that GitHub is to blame for the KeRanger Mac ransomware. (Note to readers: That last bit is tongue in anonymous cheek.)
