Ransomware is a severe and growing threat to businesses of all sizes. Our new research showed that double-extortion ransomware attacks increased by 29.9% over the past quarter, making Q1 2023 the most prolific quarter we have ever observed for that type of attack.
This alarming rise highlights the urgent need for organizations to have robust cybersecurity measures that will detect and prevent ransomware attacks. These attacks can inflict severe financial and reputational repercussions.
In this blog, we offer: approaches for managing ransomware threats, an overview of key vulnerabilities exploited for ransomware use in Q1 2023, and ways ReliaQuest can help security teams better detect and defend ransomware threats.

Ransomware operators exploit a wide array of new and older vulnerabilities in their attacks. Identifying and patching commonly exploited flaws can be crucial in preventing or minimizing the impact of cyber attacks. Three important vulnerabilities were exploited over the past quarter, leading to widespread ransomware attacks:
To learn more about vulnerabilities exploited by cybercriminals over the past quarter, check out our Q1 2023 Vulnerability Report.
The tactics, techniques, and procedures (TTPs) of ransomware groups vary widely, even within groups, because many groups operate ransomware-as-a-service (RaaS) programs. With RaaS, affiliates conduct attacks on behalf of the operators, and those affiliates’ TTPs are likely to differ from attack to attack. So, it’s difficult to identify an attacker before they deploy their ransomware.
Building resilience against ransomware requires organizations to use a defense-in-depth (DiD) strategy, taking into account the many different vectors of attack. Below are general recommendations for building resilience, for organizations of all sizes. They provide a foundation for preventing ransomware attacks.
ReliaQuest customers can use ReliaQuest GreyMatter Detect to help gain visibility into ransomware threats. GreyMatter Detect is a robust library that covers all phases of the ransomware attack lifecycle and helps customers work toward comprehensive coverage, following a DiD strategy. To maximize the value of detection, endpoint logging or visibility is required, in addition to regular reviews to pre-emptively address limited visibility.
Analysis of post-exploitation activity suggests that threat actors favor the techniques listed below; this list can be used to identify coverage gaps in customer environments.
This detects an installed service that has a suspicious name. Most legitimate services have descriptive names that make it easy to identify their function.
Typically, legitimate services are installed in their respective program folders. Receiving alerts for services executing files from anomalous directories, such as high-level directory or temp directory, can help detect potential lateral movement on persistence.
Threat actors can use PowerShell Scheduled Task Creation to execute malicious commands on a victim’s computer as a persistence mechanism.
Impacket is found to be favored by many threat actors because they use MWindows management protocols to execute remote commands from a compromised user account. This creates a unique detection opportunity during the lateral movement phase of an attack.
