Sophos, a cybersecurity company, recently published its Active Adversary Report for Business Leaders, providing an in-depth analysis of cyber adversaries' evolving behaviors and attack techniques in 2022. Data gathered from over 150 Sophos Incident Response (IR) cases revealed that attackers utilized more than 500 unique tools and tactics, including 118 "Living off the Land" binaries (LOLBins). These LOLBins, unlike malware, are executables native to operating systems, making them more challenging for defenders to block when exploited for malicious purposes. The report identified unpatched vulnerabilities as attackers' most common root cause for initial system access. Half of the investigations found that adversaries exploited 2021 vulnerabilities, ProxyShell and Log4Shell, to infiltrate organizations. Compromised credentials were the second most common root cause of cyberattacks. John Shier, field CTO at Sophos, highlighted the need for businesses to utilize tools and services to help alleviate some of the defensive burdens, allowing organizations to focus on their core priorities. The study showed that ransomware continues to be a prevalent threat, accounting for 68% of attacks investigated by the Sophos IR team and nearly three-quarters of the company's IR investigations over the past three years. Interestingly, dwell time – the period between an attack's initiation and detection – decreased in 2022 from 15 to 10 days for all attack types. For ransomware cases, dwell time dropped from 11 to 9 days, while non-ransomware attacks declined from 34 days in 2021 to 11 days in 2022. The report found no significant variations in dwell times between different organization sizes or sectors. Shier emphasized the importance of proactive monitoring and layered defenses for improved outcomes in terms of attack severity. The Sophos Active Adversary Report for Business Leaders offers organizations actionable threat intelligence and insights to enhance security strategies and defenses. The report is based on 152 incident response (IR) investigations across 31 countries, including the U.S. and Canada, the U.K., Germany, Switzerland, Italy, Austria, Finland, Belgium, Sweden, Romania, Spain, Australia, New Zealand, Singapore, Japan, Hong Kong, India, Thailand, the Philippines, Qatar, Bahrain, Saudi Arabia, the United Arab Emirates, Kenya, Somalia, Nigeria, South Africa, Mexico, Brazil, and Colombia and 22 sectors, including manufacturing, healthcare, education, and retail.
