This week the Chrome zero-days just keep on coming, and we contemplate what it means for the future. We have two interesting bits of ransomware meta news including a new tactic. We update after last week's Super Tuesday patch marathon, and examine new research into the most common source of Android malware to see where most unwanted apps come from and it's not what we would likely guess. We'll share a bit of listener feedback and an update on my work on SpinRite. Then we look at the new "SAD DNS" attack which successfully regresses us 12 years in DNS cache poisoning and spoofing attack prevention.
