What you're seeing in the Bloomberg piece is a bunch of half-truths backed by soild data. It is a BMC exploit, and they are doing it through the BMC EPROM, and even the position of the 'exploit' in the article's graphics is accurate. This is obfuscated because of an ongoing investigation. It's real, but there's purposeful misinformation, combined with a journalistic game of telephone or chinese whispers.
It's also about the worst possible way to drop and 0-day, but whatever.
