Fredrik Nordberg Almroth, co-founder of Detectify, highlights the pressing issue of the growing attack surfaces for companies, exacerbated by cloud migration and online exposure, in his talk at Hack Your Stockholm. He draws parallels between modern cybersecurity challenges and historical lessons from World War II, emphasizing the importance of identifying unseen vulnerabilities rather than focusing solely on visible threats. Almroth illustrates the consequences of neglected security practices through case studies, including vulnerabilities in Google, Patreon, and the Democratic Republic of Congo's domain management. Each example underscores how critical it is for companies to proactively manage their attack surfaces by continuously monitoring potential entry points and collaborating with ethical hackers. Almroth argues that organizations must surpass basic security measures to truly protect their digital infrastructure, advocating for a proactive approach that includes third-party testing and external attack surface monitoring to pre-emptively identify and mitigate potential threats.
