ISC Stormcast For Tuesday, May 19th, 2026 https://isc.sans.edu/podcastdetail/9936, (Tue, May 19th)
The SANS Internet Storm Center's Stormcast for May 19th, 2026 highlighted a concerning increase in observed malicious activity across the internet. Specifically, the report detailed heightened phishing campaigns and a notable uptick in observed botnet activity. This information serves as a critical early warning for security professionals to proactively monitor their networks and systems.
The Stormcast identified a surge in phishing attacks targeting various sectors, primarily focusing on credential harvesting and delivering malware. Simultaneously, there was a significant increase in the operational activity of established botnets, utilized for distributed denial-of-service (DDoS) attacks and data scraping. The ISC attributed this trend to a combination of factors, including evolving attacker tactics and the continued availability of compromised credentials.
