In the beginning of 2022, many companies around the world began calling for most, if not all, of their workforce to return to the office on a full-time basis, a phenomenon aptly referred to as “the Great Return.” Meanwhile, some companies embraced permanent hybrid work or remote setups. This diffused labor pool, together with a widened digital attack surface, has made it increasingly difficult for cybersecurity teams to keep different work structures secure — a susceptibility thread that cybercriminals are quick to pull on to launch critical attacks and exploit vulnerabilities.
We observed how malicious actors favored ransomware-as-a-service (RaaS) methods for faster deployments and bigger payouts. They also used relatively new ransomware families in high-profile attacks and increasingly targeted Linux-based systems with attacks. Ransomware operators also resorted to both novel and tried-and-tested methods to attack cloud environments.
In our midyear security roundup, we highlight the most significant security stories that made a considerable impact on the threat landscape in the first half of the year.
