Highlighting the cyber-security news from the past week in a 120 sec. read. Starting now.

Cyber Weapon

Analysts are reporting that the Petya/NotPetya ransomware is a cyberweapon.

Why is this significant?

  • Until now, malware authors created ransomware with a simple objective: encrypt files - get money. But analysts are seeing clues in the Petya/NotPetya code that makes them believe that this new “ransomware-like” threat has more in common with Stuxnet or BlackEnergy than a run of the mill ransomware.
  • Analysts say that Petya/NotPetya looks like ransomware, and behaves like ransomware, but lacks a vital piece of functionality that is common to ransomware: you can’t unlock the encrypted files.
  • This last piece means that even if victims pay the ransom, they won’t get their data back.
  • Petya/NotPetya has affected a variety of industries.

Ransomware

Windows 10 S was built with security in mind and Microsoft has claimed that, “no known ransomware” will run on their new Surface Laptop.

Why is this significant?

  • Microsoft’s claim was busted by a security researcher from Hacker House that unraveled the security integrated in the new laptop in just over 3 hours.
  • Microsoft created limitations for Windows 10 S users, in attempt to eliminate the risky behaviors of a user such as: providing store only applications; no command prompt; no access to scripting tools; no access to PowerShell.
  • A crucial element that was not removed is “enable macros” which is the initial point of how one of the first ransomware, Locky, is injected.

Cost of a Data Breach

Anthem Inc., has agreed to pay $115M in settlement fees based on the 2015 Anthem healthcare breach.

Why is this significant?

  • Anthem, Inc. is still feeling the sting from a 2015 data breach that affected 78.8M victims- referred to at the time as the biggest data breach in history.
  • Of the $115M, at least $17M will cover the cost of Experian’s 2-year credit monitoring service for the victims of the breach, as well as protect past losses related to the breach. “The settlement requires Anthem to guarantee a certain level of funding for information security, and to maintain changes to its data security systems.”
  • In a recent report ~$12B in fraud loss came from data breach victims. Will this cost eventually be an indicator in data breach settlement costs?
