Cybercriminals are constantly evolving their operations, the methods they use to breach an organization’s defenses and their tactics for monetizing their efforts. In the CrowdStrike 2022 Global Threat Report, we examined how the frequency and sophistication of ransomware attacks has grown in the past year.

The threat presented by today’s adversaries is as pervasive as it is dangerous — eCrime and state-nexus actors alike are attempting to infiltrate companies and organizations of all sizes and across all verticals. While technology is a powerful tool for performing routine or repeatable analysis, the only way to effectively hunt and contain sophisticated and determined cyber threat actors is to use the expertise and ingenuity of human threat hunters.

Adversaries often exploit legacy protocols like Windows NTLM that unfortunately remain widely deployed despite known vulnerabilities. Previous CrowdStrike blog posts have covered critical vulnerabilities in NTLM that allow remote code execution and other NTLM attacks where attackers could exploit vulnerabilities to bypass MIC (Message Integrity Code) protection, session signing and EPA (Enhanced Protection for Authentication).

CrowdStrike believes that continuous testing and evaluation by third-party organizations is critical in helping customers make informed decisions about which security solution best fits their needs. This is why CrowdStrike continues to participate in more third-party testing than any other next-gen endpoint cybersecurity vendor.

CrowdStrike Services recently investigated a suspected ransomware intrusion attempt. The intrusion was quickly stopped through the customer’s efforts and those of the CrowdStrike Falcon Complete™ managed detection and response (MDR) team, which was supporting this customer’s environment.

Recent research from CyberArk Labs presents a new technique for extracting sensitive data from the Chromium browser’s memory. However, existing access to the targeted system is required before leveraging the technique to extract the sensitive data. The technique could enable identity-based attacks involving authentication bypass using Oauth cookies that have already passed an MFA challenge.

When a breach occurs, time is of the essence. The decisions you make about whom to collaborate with and how to respond will determine how much impact the incident is going to have on your business operations.
