The security review: Jigsaw and passphrases

Welcome to this week’s security review, which includes Jigsaw & the increasing aggressiveness of ransomware, the importance of passphrases, Google’s continuing efforts to encrypt all of its services and products and the cybersecurity prowess of a 10-year-old boy from Finland.

Jigsaw and how ransomware is becoming more aggressive with new features

The threat of ransomware attacks is all too evident, with ESET’s Josep Albors reporting on how there appears to be a trend towards more aggressive variants. One example of this is Jigsaw, a variant detected by ESET as MSIL/Filecoder.Jigsaw.

He commented that “speed is where fiber optic far outshines copper”, adding: “While you have to work to get copper cabling to do 10 gigabit, fiber optics wouldn’t even be breaking a sweat.”

Google introduces HTTPS for blogspot domain names


Google announced that every blogspot domain name is to be encrypted with HTTPS. The tech giant originally launched this functionality in September 2015, but at the time it was optional for users. However, since then it has decided to fully encrypt all its products and services, and blogspot pages will now be HTTPS by default.

Third party risks ‘ a serious risk’

A study by the Ponemon Institute and Shared Assessments revealed that organizations are increasingly of the opinion that third party risks are on the rise. The respondents put this down to the impact of disruptive technologies, the authors of the paper highlighted. “It has become imperative for organizations to create formal programs for vendor risk management in order to avoid being compromised,” suggested  Dr. Larry Ponemon, chairman and founder of the Ponemon Institute.
