How much would a cybercriminal, nation state or organized crime group pay for blueprints on how to exploit a serious, currently undocumented, unpatched vulnerability in all versions of Microsoft Windows? That price probably depends on the power of the exploit and what the market will bear at the time, but here’s a look at one convincing recent exploit sales thread from the cybercrime underworld where the current asking price for a Windows-wide bug that allegedly defeats all of Microsoft’s current security defenses is USD $90,000.

Last week, I learned about a vulnerability that exposed all 866 million account credentials harvested by pwnedlist.com, a service designed to help companies track public password breaches that may create security problems for their users. The vulnerability has since been fixed, but this simple security flaw may have inadvertently exacerbated countless breaches by preserving the data lost in them and then providing free access to one of the Internet’s largest collections of compromised credentials.

It’s remarkable how quickly a stolen purse or wallet can morph into full-blow identity theft, and possibly even result in the victim’s wrongful arrest. All of the above was visited recently on a fellow infosec professional whose admitted lapse in physical security lead to a mistaken early morning arrest in front of his kids.

Email scam artists last week tricked an employee at data storage giant Seagate Technology into giving away 2015 W-2 tax documents on all current and past employees, KrebsOnSecurity has learned.
