USING AI TO ANALYSE CYBER INCIDENTS

Summary from the TLDR InfoSec newsletter

This post shows how to use AI to create a timeline of the April 2025 Marks & Spencer cybersecurity incident, which impacted contactless payments and click-and-collect services, ultimately escalating to a suspension of online orders by April 25. The timeline details the progression from initial reports on April 19th to April 26th, documenting customer experiences, official communications, and media coverage with timestamps. Although M&S has not confirmed the nature of the attack, the company's response involved taking processes offline and consulting cybersecurity experts, causing operational disruptions across over 1,000 stores and a temporary 5% drop in their share price.
