Information Security Timelines

During May 2026 I collected 165 events: Cyber Crime accounted for 73.8% of events, Malware remained the dominant weapon (48.8%) and Information & Communication was hit the most (37.6%)

The threat landscape in May H2 2026 was driven by cyber crime and dominated by malware. Exploitation of public-facing app vulnerabilities continued to play an important role, similarly to supply chain attacks.

The threat landscape during May H1 was dominated by cyber crime and characterized by malware attacks, while the exploitation of public-facing applications led the initial access.

In April 2026, Cyber Crime continued to lead the Motivations, once again ahead of Cyber Espionage. Cyber Warfare took the third place, ahead of Hacktivism.

In the second timeline of April 2026 I collected 108 events, corresponding to an average of 7.2 events per day, a number that confirms a growing trend, driven by the increasing number of supply chain attacks, compared to the previous timeline, where I collected 94 events (6.27 events/day).

I aggregated the statistics created from the cyber attacks timelines published in the first quarter of 2026. In this period, I collected a total of 528 events (5.87 events/day) dominated by Cyber Crime with 66%, followed by Cyber Espionage with 18%, Hacktivism with 3%, and finally Cyber Warfare with 2%.

The first timeline of April 2026 brings an evolution in terms of methodology: from now on I will map the initial access techniques with the MITRE ATT&CK model. I also decided to merge the categories of Finance and Fintech in the sectors chart. From an event perspective, the first half of April 2026 confirmed a sustained trend…

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.
