Ransomware: Quis custodiet ipsos custodes
Many claim that "ransomware" is due to cybersecurity failures. It's not really true. We are adequately protecting users and computers. The failure is in the inability of cybersecurity guardians to protect themselves. Ransomware doesn't make the news when it only accesses the files normal users have access to. The big ransomware news events happened because ransomware elevated itself to that of an "administrator" over the network, giving it access to all files, including online backups.
Generic improvements in cybersecurity will help only a little, because they don't specifically address this problem. Likewise, blaming ransomware on how it breached perimeter defenses (phishing, patches, password reuse) will only produce marginal improvements. Ransomware solutions need to instead focus on looking at the typical human-operated ransomware killchain, identify how they typically achieve "administrator" credentials, and fix those problems. In particular, large organizations need to redesign how they handle Windows "domains" and "segment" networks.
I read a lot of lazy op-eds on ransomware. Most of them claim that the problem is due to some sort of moral weakness (laziness, stupidity, greed, slovenliness, lust). They suggest things like "taking cybersecurity more seriously" or "do better at basic cyber hygiene". These are "unfalsifiable" -- things that nobody Continue reading
