CrowdStrike’s Cloud Threat Research team discovered a zero-day vulnerability (CVE-2022-0811) in CRI-O (a container runtime engine underpinning Kubernetes). Dubbed “cr8escape,” when invoked, an attacker could escape from a Kubernetes container and gain root access to the host and be able to move anywhere in the cluster.
Over recent months, the CrowdStrike Falcon OverWatch™ team has tracked an ongoing, widespread intrusion campaign leveraging bundled.msi installers to trick victims into downloading malicious payloads alongside legitimate software. These payloads and scripts were used to perform reconnaissance and ultimately download and execute NIGHT SPIDER’s Zloader trojan, as detailed in CrowdStrike Falcon X™ Premium reporting.
With chaos seemingly surrounding us in security, it can be hard to cut through the noise. How do you detect and prioritize evolving threats and what tools should you use to address them? With new attacks and vulnerabilities on the rise, combined with ineffective security tools and the industry’s ongoing skill shortage, security operations center (SOC) teams struggle to protect organizations from adversaries.
With the growing risk of identity-driven breaches, as seen in recent ransomware and supply chain attacks, businesses are starting to appreciate the need for identity security. As they assess how best to strengthen identity protection, there is often an urge to settle for security features or modules included in enterprise bundles from the same vendor providing their identity or identity and access management (IAM) layer.
The security problems that plague organizations today actually haven’t changed much in 30 years. Weak and shared passwords, misconfigurations and vulnerabilities are problems that have tormented the industry for years and persist to this day. What’s changed is the speed and sophistication at which today’s adversary can weaponize these weaknesses.
Alert overload is practically a given for security teams today. Analysts are inundated with new detections and events to triage, all spread across a growing set of disparate, disconnected security tools. In fact, they’ve burgeoned to such an extent that the average enterprise now has 45 cybersecurity-related tools deployed across its environment.
Modern cyberattacks are multifaceted, leveraging different tools and techniques and targeting multiple entry points. As noted in the CrowdStrike 2022 Global Threat Report, 62% of modern attacks do not use traditional malware and 80% of attacks use identity-based techniques, meaning that attacks target not only endpoints, but also cloud and identity layers with techniques that many legacy solutions have no visibility of or means of stopping.
At the start of 2022, CrowdStrike Intelligence and CrowdStrike Services investigated an incident in which PROPHET SPIDER exploited CVE-2021-22941 — a remote code execution (RCE) vulnerability impacting Citrix ShareFile Storage Zones Controller — to compromise a Microsoft Internet Information Services (IIS) web server. The adversary exploited the vulnerability to deploy a webshell that enabled the downloading of additional tools.
