Partnering to Stop Cybercrime: Countering the Cyber Extortionists

This past year, the cyberattack surface has drastically changed, creating opportunities for cybercriminals to exploit. After a year that saw one of the largest and fastest transformation in work patterns, security teams now preside over an ecosystem that is more distributed and heterogeneous than ever before. Digital transformation initiatives advanced rapidly as the cyberattack surface expanded to include living rooms, kitchens, home networks, and personal devices. The remote workforce behaves very differently than the office workforce, accessing the network at unpredictable hours as they balance the demands of work and family. As a result, network traffic has changed beyond recognition. Defenders must adapt monitoring systems and trigger points, or risk leaving opportunity for threat actors to use atypical patterns to mask infiltration attempts.
Against this rapidly changing backdrop, some things remain the same: one industry that has not been disrupted by COVID-19 is cybercrime. In fact, cybercriminals have capitalized on the expanded attack surface. The frequency of attacks is high, sophistication continues to evolve, and breaches are the inevitable result.
According to Cybersecurity Ventures, cybercrime is expected to cost the world $10.5 Trillion annually by 2025. Cybercriminals are collaborating with each other on the dark web to iterate faster and work at scale. The cybersecurity industry should be doing the same to help combat the ever-growing industrialization of cybercrime. To foster better collaboration and cyber ground truth, VMware’s Security Business Unit and Accenture’s Cyber Threat Intelligence group are teaming up to deliver relevant security research into the criminals’ kill chain to expose tactics, techniques, and procedures (TTP) that enable security teams to focus their prevention detection and response programs.
Our threat research uses MITRE ATT&CK® – a comprehensive framework to document adversary TTPs - to focus on TTPs relevant to the initial stages of infection that precede a ransomware event. We will also be focused on the Time to Ransom (TTR) to help teams to better create playbooks and responses when an infection occurs. Focusing on the tools and tactics used prior to a ransomware lockdown will identify detection opportunities for security teams to immediately implement.
Accenture and VMware have found that, although, the TTR can be as short as a couple of hours, often the TTR will be at least a couple of days and as long as several months. Ransomware groups use tried and true methods to gain initial access to a network, establish a foothold, and get access to the resources desired through moving laterally and harvesting credentials. Each of these activities provides opportunities for detection and remediation before the ransomware is deployed. Time is not on our side when it comes to cyber criminals, and we believe this research will prove valuable and relevant to combatting the criminals.
