How a SIEM solution can help you defend against ransomware These events on their own are basic system processes that generate logs, emphasizing the importance of a strong log management and reporting tool. The ransomware attack involved steps such as installing services, establishing processes, modifying keys, and renaming files. ![]() This just goes to show how time is a crucial factor when it comes to protecting against cyberattacks. The REvil group, however, beat it in the race and executed the attack before the patch was rolled out. When Kaseya learned of the vulnerabilities, it started working on a patch. ![]() The Dutch Institute for Vulnerability Disclosure noticed and informed Kaseya about vulnerabilities in VSA, several of which were eventually exploited to execute the attack. For this reason, monitoring and restricting privileges to entities is essential. It’s important to note that IT management systems like the one targeted have unrestricted access to all components in the network, making it easier for attackers to exploit privileges and execute code at will. Next, it overwrites the actual MsMpEng.exe file, which runs the Windows Antimalware Service Executable, with an outdated version that allows DLL side loading of the Windows Defender encryptor.įinally, it uses the encryptor to encrypt the system with higher privileges. REvil now deletes any artifacts to ensure there are no footprints left behind. It then uses CertUtil.exe, an admin command-line tool used for manipulating certification authority, to decode the agent.crt file to agent.exe. Next, it shuts down crucial services such as Windows Defender’s real-time monitoring, folder protections, file scanning, network monitoring, and antivirus software. REvil uses the Kaseya agent monitor, agentmon.exe, to write a file named agent.crt (to be used as the ransomware dropper) to the path c:kworking. When this update is installed on a system, it executes a script that performs a series of steps to start off the infection as follows: REvil ransomware was delivered to the targets through a hotfix. While Kaseya tried to take remedial action by shutting down cloud-based installations and asking customers to shut down on-premises installations, the damage had already been done. ![]() The REvil group demanded compensation of $70 million in BTC in return for the decryption key. Once they compromised the VSA servers, the attackers deployed REvil ransomware and encrypted thousands of devices across MSPs. The vulnerabilities made it possible for the attackers to access an exposed service on VSA servers, bypass authentication, and execute code remotely. It’s been revealed that the attackers discovered and exploited zero-day vulnerabilities in Kaseya VSA, a remote monitoring and management product. ![]() So, what exactly transpired in what most cybersecurity experts are calling the largest criminal ransomware attack on record? The attack made a huge impact, affecting several MSPs and thousands of their customers. On July 2, 2021, the cybersecurity world woke up to yet another ransomware attack-this time, the victim was Kaseya, a software enterprise that provides IT management solutions predominantly to managed service providers (MSPs). ![]()
