Trust relationships between systems and leverage Windows Management Instrumentation (WMI), SMB, or PsExec to bind methods and execute payloads.Get credentials or Windows token extraction from disk or memory.Quite often, these are automated tools that help the attackers to: Threat actors also introduce discrete scripts within targeted environments. Deploy encryptors across the environment using Windows batch files.Deploy encryptors with Microsoft Group Policy Objects (GPOs) and existing software deployment tools the victim organization utilizes.Manually run encryptors on targeted systems.Evolution of Tactics, Techniques, and ProceduresĪfter penetrating an environment and gaining administrator-level privileges, threat actors use a variety of tactics, techniques, and procedures. An attacker is able to complete their ransomware in a matter of hours if not minutes in some environments,” he added. Using that, allows the attacker to further go into the main control and key servers in the environment. “There is a lateral movement which is typically the exploitation of credentials. Going after these other sets of data becomes important to ensure that the attacker is able to effectively hold ransom,” spoke Eric Howard, the Cisco security technical leader, during his session on ‘Why You Need a First and Last Line of Defense to Protect Against Ransomware.’ “Once the attackers are in control of the system, it is never enough to just have one as data lives in multi systems. The attackers then hold those systems hostage until a ransom is paid. Ransomware results from multistage compromise where several components are involved in its successful delivery at an endpoint, allowing attackers who are motivated to control and contain those endpoints to get the data they want by locking away files from users.

To bring Emotet down, over 12 countries joined hands to take down a globally distributed botnet. “To combat the threat actors, cybersecurity really does require coordinated efforts. Milbourne, while conducting a session on ‘Which Cybersecurity Risks Will Prevail in 2021’, said, “Emotet used to trick users to install the initial piece of infection while email brought ‘trickbots’ and other remote access utilities that infect the system, attempt to move laterally, and ultimately in many cases deliver ransomware infections.”Įmotet going offline has a tremendous impact, he said. ![]() The malware was designed to infiltrate systems and exfiltrate sensitive information, thereby posing a potent threat to multiple sectors. In January 2021, law enforcement authorities worldwide took down the Emotet botnet, which was first observed in 2014. At Spiceworld Virtual 2021, Grayson Milbourne, security intelligence director at Webroot, highlighted trends that impacted critical industries, geographies, companies, and people and spoke about how organizations can destroy threats like ransomware in the year ahead.Īmid ongoing cyberattacks, the shutdown of Emotet, one of the most prolific malware variants, arrived as good news for the cybersecurity industry. Various cyber threats emanating from state actors and ransomware gangs kept organizations and governments on their toes. The past year served as the moment of reckoning for the cybersecurity sector. ![]()
