Unmasking the Hidden: Real-World Attack Surface Discoveries from the Wild
As organizations grow into complex groups with subsidiaries, joint ventures, and global operations, managing the external attack surface becomes increasingly challenging. This session dives deep into two essential pillars of External Attack Surface Management (EASM): Discovery and Assessment.In the Discovery segment, we introduce practical techniques for identifying unknown digital assets across corporate structures using signals like WHOIS, RDAP, passive DNS, and third-party analytics IDs—tools that help reduce noise and increase coverage across shadow assets.In the Assessment segment, we focus on a critical but often overlooked gap: evaluating vulnerabilities in VPN appliances and other exposed network infrastructure that traditional vulnerability scanners cannot reliably assess. We will share techniques to fingerprint server responses and infer vulnerability status—empowering defenders to spot high-risk exposures missed by common tools. This is EASM in action, straight from the wild.
