Phishing attacks have grown far more complex in recent years. Attackers no longer rely on simple static pages to steal credentials.
Instead, they build layered redirect chains, execute dynamic scripts, and load content in stages, making it much harder for security teams to see what a victim experienced when clicking a suspicious link. This shift has quietly outpaced the tools most organizations use.
The problem hits Security Operations Center teams the hardest. When a suspicious URL lands in the queue, an analyst typically runs it through multiple tools, manually traces redirects, collects screenshots, and inspects network traffic before reaching a conclusion.
This process can take up to an hour per URL, and even then, critical details often still slip through the gaps. Analysts at ANY.RUN identified a significant blind spot in how modern phishing URLs are investigated.
They noted that most investigation workflows are built around static analysis, making them blind to the dynamic behaviors that define today’s phishing campaigns.
ANY.RUN said in a report shared with Cyber Security News (CSN) that it redirect chains, injected scripts, iframe activity, and form interactions all happen inside the browser, and most tools never capture any of it.
To address this, the team introduced a capability called in-browser data inspection, which brings full browser-level visibility into the URL analysis workflow.

Every redirect, every script execution, every DOM change, and every piece of user-facing content is captured in real time, within a single interface.
This removes the need to jump between tools or reconstruct attack behavior from disconnected data sources.
The impact is significant. What once took an hour of manual work is now available within seconds, giving analysts everything they need to make fast, confident decisions about whether a URL is malicious or safe.
In-Browser Data Inspection Lets Analysts Track Phishing Attack Flow
The suspicious URL is loaded and executed inside a real browser environment, not just scanned at the surface level. Everything the browser does during that execution is recorded and made available in a structured, easy-to-navigate interface.
This includes the full page execution tree, showing every redirect and activated iframe from the initial URL to the final page a victim would have seen.
Analysts can explore detailed HTTP request data to understand how redirect chains are built and where credentials may be collected.

The HTML DOM Changes tab reveals code fragments injected after the page loaded, which is exactly the kind of hidden content that static analysis tools miss.
Color highlights and tags within the interface point directly to pages that triggered detections, cutting down manual review time.
Beyond a single URL, collected indicators such as domains, IP addresses, and file hashes are automatically gathered from the analyzed page.
These can be used to pivot across related infrastructure or build custom YARA detection rules.
According to the report, a single YARA rule built from one phishing page snapshot identified 14 related samples inside the threat intelligence database.
Closing the Gap in SOC Phishing Workflows
Visibility gaps in traditional URL investigation create real operational challenges. Without browser-level evidence, Tier 1 analysts often escalate cases they lack confidence in, adding pressure on senior team members and slowing the entire response process.
When escalation does happen, the receiving analyst typically has to start over because handoffs rarely include the full context needed to act quickly.
In-browser data inspection changes this by ensuring every escalation includes a complete evidence package, from redirect chains to rendered screenshots to DOM artifacts.
This reduces mean time to respond and improves triage accuracy at every level. Analysts across all tiers can work from the same clear, browser-native view of what the attacker actually built.
Security teams are encouraged to use the built-in SOC-ready reports, which convert complex investigation findings into structured, decision-ready intelligence.
These reports simplify escalation, incident response coordination, and stakeholder communication. As phishing continues to grow in volume and sophistication, browser-level visibility is fast becoming a baseline requirement for any modern security operations team.
