Flashpoint

First discovered in April 2026, CastleStealer is a C#-based information-stealing malware that has continued to add new capabilities since its emergence. Newer samples analyzed by Flashpoint can bypass app-bound encryption in Chromium-based browsers, execute commands remotely, and exfiltrate stolen information in small encrypted transmissions rather than a single large archive.

October 7, 2026 Share: In today’s threat landscape, speed and actionable context are critical. When a high-priority threat emerges, pairing best-in-class threat intelligence data with hyper-responsive human expertise ensures organizations can act immediately and with confidence.

Vulnerability and exposure management (VM) teams need critical metadata and context that clearly show which issues pose an immediate risk to their organization. While traditional VM frameworks tell defenders how severe a vulnerability may be, they do not provide visibility into how likely threat actors are to exploit it. This leaves security teams overwhelmed in patch backlogs without a clear strategy for prioritization. Nowhere is this prioritization gap more dangerous than with ransomware.

Modern Endpoint Detection and Response (EDR) platforms have made traditional malware injection techniques significantly harder to execute. In most cases, if a threat actor attempts to write malicious code into a process, an alert will fire. However, that sense of security is being actively challenged as cybercriminals and red teams find new ways to blend malicious payloads into standard operating system routines.

In this blog we explore the recently published Forrester Wave™: External Threat Intelligence Service Providers, Q3 2026 report which named Flashpoint a Customer Favorite, along with naming the organization a Strong Performer with the highest scores possible in the criteria of: Fraud Intelligence, Executive Protection, and Pricing Flexibility and Transparency.

When physical threats manifest in the real world, every minute counts. Whether tasked with Executive Protection, securing critical infrastructure, or monitoring live events, security teams face a constant challenge: turning massive volumes of noisy online chatter into rapid, actionable insight. For traditional workflows, surfacing relevant situational awareness required complex Boolean query construction, exhaustive lists of regional keywords, and constant tweaking of syntax.

The Flashpoint Threat Intelligence Brief: Middle East cuts through headline noise to deliver tactical, ground-level intelligence for government agencies, corporate security leads, and global logistics teams—turning Flashpoint’s primary source intelligence into proactive risk mitigation.

In our latest webinar, Flashpoint Vice President of Intelligence, Ian Gray, briefed security leaders on the evolving threat environment, providing critical insights from the Flashpoint Global Threat Intelligence Report (GTIR): 2026 Midyear Edition. The threat landscape has developed at a striking pace with Flashpoint tracking over 22 million illicit AI discussions, 7.4 million compromised hosts yielding 1.7 billion stolen credentials, and over 21,600 disclosed vulnerabilities in just six months.

Hacktivism used to be perceived as digital graffiti, with lone-wolf threat actors defacing government websites or temporarily crashing banking portals to make a political point. However, Flashpoint is tracking a fundamental shift in how these groups operate. Modern hacktivism is evolving into a disciplined component of global hybrid warfare, capable of bridging digital disruptions with tangible real-world impact.

Flashpoint’s monthly analysis of insider threat recruitment, illicit access advertising, and threat actor activity targeting enterprise environments. Unknowingly, a member of key personnel is living two separate lives. On the clock, they are a highly-trusted systems administrator, but in their personal time, they moonlight on the deep and dark web, advertising their trust and access to the highest bidder.
