NotPetya – the most devastating cyberattack since the creation of the internet



In 2017 malware known as notPetya sabotaged the computers of thousands of businesses worldwide, from large international companies such as shipping giant Maersk to local businesses like Cadbury’s Tasmanian chocolate factory. Global law firm DLA Piper was among the many victims, crippling operations for days as lawyers at the firm had limited access to their computer systems or email.

Total losses have been estimated at more than $10 billion. Starting in the Ukraine, the malware spread rapidly by encrypting computers’ master boot records making data permanently unavailable.
