EASM Uncovers Forgotten Perimeter Assets Including 11-Year-Old Servers Invisible to Standard Scanners

EASM solutions continuously discover external attack surfaces by starting from public data such as company names, domains, WHOIS records, Certificate Transparency logs, and internet-wide scanners like Shodan and Censys. Unlike traditional vulnerability scanners that only check assets from a predefined list, EASM maps unknown shadow IT including forgotten test servers, abandoned marketing subdomains, exposed APIs, and cloud buckets left open to the internet. The technology follows the same reconnaissance path used by attackers and has become essential for mature vulnerability management programs after years of being considered exotic. Major vendors including Palo Alto Networks Cortex Xpanse, CyCognito, Qualys, Rapid7, and Tenable now lead the market, while Russian providers such as Positive Technologies PT EASM, BI.ZONE EASM, and CyberOK PenOps have grown rapidly since 2022. Without an established process for prioritization and remediation, EASM implementations risk generating overwhelming alert volumes rather than reducing risk. The approach is now viewed as a core component of Continuous Threat Exposure Management (CTEM) frameworks.

Recon in Bug Bounty: Spotting Anomalies Instead of Chasing Known Vulnerability Patterns

The article explains that effective reconnaissance in Bug Bounty programs goes far beyond automated subdomain enumeration with tools like subfinder or httpx. It emphasizes building a mental model of the target application by analyzing policy documents, infrastructure changes via Censys and Shodan, and identifying behavioral anomalies rather than matching textbook vulnerability patterns. A detailed case study describes how a hidden legacy endpoint on ibm.com was discovered during passive and active reconnaissance, leading to the identification of a time-based Blind SQL Injection vulnerability confirmed with sqlmap. The author stresses that recon is a continuous process involving hypothesis testing, understanding service trust boundaries, and evaluating real security impact for triage teams. Practical advice includes reviewing HackerOne reports for context, maintaining motivation through interesting targets, and revisiting programs as infrastructure evolves. The piece also covers how JavaScript analysis and direct endpoint interaction help map authorization flows and weak links between microservices.

Statistical Analysis in OSINT: Tools, Methods and Real-World Intelligence Applications

The article explains why statistical processing has become an essential component of professional OSINT work when analysts face large volumes of raw data. It outlines five core tasks that statistical methods solve: actor profiling, disinformation monitoring through time-series and graph analysis, financial intelligence, geospatial verification, and threat assessment. The text compares popular tools including Maltego, Gephi, Python, R, Power BI, Tableau and SpiderFoot, stressing that real investigations usually combine several of them. Detailed examples show how Pearson correlation, Louvain clustering and TF-IDF or BERT embeddings help identify coordinated botnets in social media. Famous leaks such as Panama Papers and Pandora Papers are presented as landmark cases where regression models, cluster analysis and network graphs exposed hidden ownership structures. The piece also lists open statistical sources from national agencies, international organisations and technical platforms, and reviews key mathematical techniques from basic descriptive statistics to ARIMA, CUSUM, DBSCAN and dimensionality reduction methods.

OSINT for the Lazy Part 16: Discovering Hidden Corporate Infrastructure Through Shodan

The article explains how Shodan differs from traditional search engines by indexing internet-connected devices such as servers, routers, cameras, databases, and admin panels rather than web pages. It provides ten practical search techniques including hostname queries, SSL certificate searches, ASN lookups, IP range scans, and targeted queries for development environments, admin panels, and databases. Examples demonstrate how forgotten dev.company.com or staging.company.com hosts, open Jenkins or Grafana dashboards, and exposed MongoDB or Redis instances can be located with simple filters. The piece walks through a five-step real-world workflow that combines domain, SSL, organization, and service-title searches to map a target company’s infrastructure. It emphasizes that Shodan only reveals services already exposed to the internet and does not perform any exploitation. Common root causes listed include forgotten test servers, rushed DevOps configurations, and misconfigured firewalls. The article concludes with a reminder that many organizations remain unaware their internal systems are visible to anyone using the same techniques.
