Season’s greetings! While this is the season for goodwill, it would seem that cybercriminals also have good reason to be jolly. In 2023, cybercriminals continued to feast on vulnerabilities which led to zero-day exploits (attacks exploiting a previously unknown vulnerability before any available remediation) and N-day attacks (a compromise achieved through exploiting a vulnerability, despite a patch being available). This issue of CyberSense reflects on the growing challenge of zero-day exploits and N-day attacks, and what we can do to manage the threat.

Since 2005, data breaches have been on the rise, with millions of records exposed in each breach. While data breaches are not new, the proliferation of electronic data has made us more susceptible to such breaches. Data such as credit card information, passwords, personal contact details may be compromised whenever a data breach occurs.

As 2022 comes to a close, this issue of CyberSense provides a summary of the key cybersecurity threats and trends observed over the past 12 months, and a taste of what to expect in 2023.
