As World Backup Day reminds us, robust backups are integral to healthy information security practices of any organization. This is doubly true for those operating in critical sectors.

WeLiveSecurity sat down with David Harley to get a better understanding of Critical Infrastructure and the role he has played in the area throughout his career.

Tracing the evolution and subsequent revolution of ransomware

More than three dozen cybercrime and digital forensics experts from 23 countries have investigated a simulated attack on a bank that had been carried out through an IoT device.

The big challenge with IoT devices is that they are all different: Each manufacturer has its own firmware, uses different protocols, and designs its own architecture. So, the first step before carrying out any analysis is to understand the architecture, find out what components are involved, and how they interact and communicate among themselves.

The Internet of Things (IoT) can be a network of connected convenience but this should not come at the expense of safeguarding your privacy and the personal data that connected devices collect and share.

The vulnerability of critical infrastructure, including energy grids, to cyberattacks has been a growing concern worldwide. Many nations have been scrambling to improve their defenses vis-à-vis threats faced by services that are critical to the continuity of our daily lives.

Ransomware in 2017 saw users and businesses across the globe trying to cope with campaigns such as Petya and WannaCryptor. Not to be outdone, Android ransomware had a year full of innovative infiltration and rougher extortion as highlighted by the latest ESET research whitepaper.
