Information Security Timelines

After the cyber attacks timelines, it’s time to publish the statistics for March 2026 where I collected and analyzed 282 events: a sharp increase compared to the 176 events of the previous month. In March 2026, Cyber Crime continued to lead the Motivations chart with 64%, ahead of Cyber Espionage at number two with 15%. Hacktivism took over the third position with 6%, ahead of Cyber Warfare with 3%.

The second half of March 2026 has been very active from an infosec standpoint, with 124 events and a threat landscape dominated by malware. As always, cyber crime led the motivations chart with 65%, slightly up from the previous timeline.

In the first half of March 2026 I collected 95 events (6.34 events/day) with a threat landscape dominated by malware once ahead of account takeovers and ransomware.

After the cyber attacks timelines, it’s time to publish the statistics for February 2026 where I collected and analyzed 176 events. In February 2026, Cyber Crime continued to lead the Motivations chart with 62%.

In the second half of February 2026 I collected 80 events with a threat landscape dominated by malware with 42%, ahead of account takeovers and ransomware.

In the first half of February 2026 I collected 96 events (6.4 events/day) with a threat landscape dominated by malware with 33%, (it was 38% in the second half of last month, once again ahead of ransomware (up to 20% from 14%), and account takeovers, down to 8% from 14%.

In this blog post I am collecting the campaigns that show evidence of being AI-generated, or make use of AI tools to increase their impact. As always I will continue to update the list as soon as new campaigns emerge.

After the cyber attacks timelines (part I and part II), it’s time to publish the statistics for January 2026 where I collected and analyzed 178 events. In January 2026, Cyber Crime continued to lead the Motivations chart with 76%, ahead of Cyber Espionage at number two with 19%, and Cyber Warfare with just three events.

After the first timeline of January 2026, it’s time to publish the list of the main cyber attacks occurred in the second half of the month, between 16 and 31 January 2026.

Here’s a collection of the main mega breaches (that is data breaches with more than one million records compromised and possibly leaked) during 2026. The information is derived from the cyber attacks timelines that I published, normally, on a bi-weekly basis.
