Context & Background

The SANS Internet Storm Center (ISC) has long been a trusted source of real-time cybersecurity information, providing daily updates on emerging threats, vulnerabilities, and attack trends. Their “Stormcast” is a regular digest that reflects the collective observations of their global network of researchers and analysts. The broadcast on August 18th, 2025, arrives at a time when several overarching trends are profoundly influencing cybersecurity: the persistent and evolving nature of ransomware, the growing threat of supply chain attacks, the increasing use of artificial intelligence (AI) in both offensive and defensive operations, and the ongoing challenges posed by phishing and social engineering tactics.

Ransomware continues to be a significant problem, with attackers demanding ever-larger sums and employing more aggressive tactics, such as double extortion (exfiltrating data before encrypting it and threatening to release it publicly). Supply chain attacks, which target less secure third-party vendors to gain access to their larger, more secure clients, have proven to be particularly damaging, as demonstrated by past incidents that disrupted numerous organizations simultaneously. The integration of AI into cyberattacks presents a dual-edged sword. While AI can enhance defensive capabilities by enabling faster threat detection and response, it can also be weaponized by attackers to create more sophisticated phishing campaigns, automate vulnerability discovery, and craft evasive malware.

Social engineering remains a cornerstone of many cyberattacks. Phishing emails, spear-phishing attacks, and vishing (voice phishing) continue to exploit human psychology to trick individuals into divulging sensitive information or executing malicious code. The increasing sophistication of these attacks, often personalized and contextually relevant, makes them particularly effective. Understanding the historical context of these persistent threats provides a crucial backdrop for evaluating the specific issues highlighted in the August 18th Stormcast.
