In 2022, the threat of cyber-attacks, hacks, and security breaches loomed large, with numerous high-profile incidents impacting companies and individuals alike. The year saw a range of cyber security threats, from data breaches and phishing schemes to DDoS attacks. Both in terms of cybersecurity and business generally, the past couple of years have been anything but typical. The COVID-19 pandemic has fundamentally altered how commerce is conducted. Cybercriminals have responded by adapting their strategies to the new environment.

While the years 2020 and 2021 saw a particularly high number of cyberattacks, there are few signs that things will return to “normal” in 2022. Cyber threat actors have tested new strategies and techniques and have successfully incorporated them into their standard toolkits. As the effects of cyberattacks were felt well beyond their intended target companies in 2021, a number of cyberattack operations and cyber threat actors rose to prominence. As cybercrime becomes more professionalized and cyber threat actors seek to maximize the value or impact of their attacks, the modern threat environment is made up of bigger, flashier, and higher-impact strikes.
