In the first blog post of this 3-part series, we introduced what rapid cyberattacks are and illustrated how they are different in terms of execution and outcome. Next, we will go into some more details on the Petya (aka NotPetya) attack.
Rapid cyberattacks like Petya and WannaCrypt have reset our expectations on the speed and scope of damage that a cyberattack can inflict. The Microsoft Enterprise Cybersecurity Group Detection and Response team worked extensively to help customers respond to and recover from these kinds of attacks.

But this picture has changed and today all it takes is a sophisticated e-mail phishing for an identity.
Adopting reliable attack methods and techniques borrowed from more evolved threat types, ransomware attained new levels of reach and damage in 2017.
Currently three exploits have been demonstrated as technically possible. In partnership with our silicon partners, we have mitigated those through changes to Windows and silicon microcode.
The trend towards increasingly sophisticated malware behavior, highlighted by the use of exploits and other attack vectors, makes older platforms so much more susceptible to ransomware attacks. From June to November 2017, Windows 7 devices were 3.4 times more likely to encounter ransomware compared to Windows 10 devices.

Introducing new video on best practices from the Microsoft Cyber Defense Operations Center Ask any CISO or cybersecurity professional about their greatest security challenge, and it’s a good chance the answer will be “the actions of our people.
On Friday May 12th, and for several days afterwards, more than a quarter-million computers around the world fell victim to the ransomware known as WannaCrypt or WannaCry. As that recent event has shown, malicious actors bring nearly boundless time and skill to commit cybercrime that can cause harm to millions of people.
Multiple high-profile incidents have demonstrated that ransomware can have catastrophic effects on all of us.
The unprecedented scale and sophistication of modern cyberthreats, combined with the rapidly disappearing IT perimeter, means that while preventing an attack from becoming a breach is ideal, it is no longer realistic. Microsoft proactively monitors the threat landscape for those emerging threats, to help better protect our customers.
