🕷️ Scattered Spider, Marks & Spencer, and the Case for Proactive External Threat Management

Introduction In a digital age where threat actors evolve faster than ever, even the most recognized global brands are not immune to cyber disruption. The recent incident involving Marks & Spencer is a sobering reminder of how critical it is to proactively manage external threats. While attribution of the attack is ongoing, the methods used align disturbingly well with tactics employed by the threat group known as Scattered Spider.

What makes this incident particularly noteworthy is that a detailed threat advisory about Scattered Spider was publicly available before the attack occurred. This raises a crucial question: Are organizations truly leveraging available intelligence to prevent foreseeable breaches?

Scattered Spider: A Known Threat, A Missed Signal Published weeks prior to the Marks & Spencer incident, the advisory warned of Scattered Spider's sophisticated phishing infrastructure, domain spoofing tactics, and use of a custom-built malware strain known as Spectre RAT. The group had already been targeting high-profile companies including T-Mobile, Nike, Twitter/X, and Louis Vuitton.

Key highlights from the advisory included:

• Deployment of Phishing Kit v5, capable of impersonating multiple brands under a single domain.

• Use of dynamic DNS, rented subdomains, and domains spoofing authentication providers (e.g., "twitter-okta[.]com").

• A continuously evolving malware arsenal built for persistence and stealth.

These indicators were not theoretical. They were published, documented, and actionable.

The Cost of Inaction The Marks & Spencer situation illustrates a painful reality: having access to threat intelligence isn't enough — it must be actively integrated into your defense posture. When threat actors operate beyond your perimeter, visibility becomes your first line of defense.
