In 2018, the cybersecurity landscape was marked by significant vulnerabilities and breaches, highlighting the urgent need for stronger security measures. Major incidents included the Meltdown and Spectre vulnerabilities affecting nearly all computing devices, the Facebook “View As” feature hack compromising 50 million users, and Marriott's data breach exposing information of 500 million guests. The year also saw numerous companies suffer from misconfigured AWS S3 buckets, prompting Amazon to enhance privacy settings, and the implementation of GDPR, which immediately resulted in fines for Google and Facebook. Magecart's theft of credit card information via compromised third-party JavaScript, Reddit’s experience with SMS 2FA vulnerabilities, and the Drupalgeddon v2.0 vulnerability demonstrated the persistent threat of cyberattacks. Google's Parisa Tabriz urged companies to adopt long-term security strategies, emphasizing the need for proactive defense and a security-centric culture. Looking ahead to 2019, experts anticipate an increase in cloud-related security issues, serverless architecture vulnerabilities, and a shift towards proactive security practices fueled by regulations like GDPR and the rise of DevSecOps.
