Security Flaw in Styra's OPA Exposes NTLM Hashes to Remote Attackers

Oct 22, 2024 Vulnerability / Software Security
Details have emerged about a now-patched security flaw in Styra's Open Policy Agent ( OPA ) that, if successfully exploited, could have led to leakage of New Technology LAN Manager ( NTLM ) hashes. "The vulnerability could have allowed an attacker to leak the NTLM credentials of the OPA server's local user account to a remote server, potentially allowing the attacker to relay the authentication or crack the password," cybersecurity firm Tenable said in a report shared with The Hacker News. The security flaw, described as a Server Message Block (SMB) force-authentication vulnerability and tracked as CVE-2024-8260 (CVSS score: 6.1/7.3), impacts both the CLI and Go software development kit (SDK) for Windows. At its core, the issue stems from an improper input validation that can lead to unauthorized access by leaking the Net-NTLMv2 hash of the user who is currently logged into the Windows device running the OPA application. However, for this to work, the victim
Cybercriminals Exploiting Docker API Servers for SRBMiner Crypto Mining Attacks

Cybercriminals Exploiting Docker API Servers for SRBMiner Crypto Mining Attacks

Oct 22, 2024 Docker Security / Cloud Security
Bad actors have been observed targeting Docker remote API servers to deploy the SRBMiner crypto miner on compromised instances, according to new findings from Trend Micro. "In this attack, the threat actor used the gRPC protocol over h2c to evade security solutions and execute their crypto mining operations on the Docker host," researchers Abdelrahman Esmail and Sunil Bharti said in a technical report published today. "The attacker first checked the availability and version of the Docker API, then proceeds with requests for gRPC/h2c upgrades and gRPC methods to manipulate Docker functionalities." It all starts with the attacker conducting a discovery process to check for public-facing Docker API hosts and the availability of HTTP/2 protocol upgrades in order to follow up with a connection upgrade request to the h2c protocol (i.e., HTTP/2 sans TLS encryption). The adversary also proceeds to check for gRPC methods that are designed to carry out various tasks

5 Steps to Boost Detection and Response in a Multi-Layered Cloud

5 Steps to Boost Detection and Response in a Multi-Layered Cloud

Oct 14, 2024 Cloud Security / Vulnerability
The link between detection and response (DR) practices and cloud security has historically been weak. As global organizations increasingly adopt cloud environments, security strategies have largely focused on "shift-left" practices—securing code, ensuring proper cloud posture, and fixing misconfigurations. However, this approach has led to an over-reliance on a multitude of DR tools spanning cloud infrastructure, workloads, and even applications. Despite these advanced tools, organizations often take weeks or even months to identify and resolve incidents.  Add to this the challenges of tool sprawl, soaring cloud security costs, and overwhelming volumes of false positives, and it becomes clear that security teams are stretched thin. Many are forced to make hard decisions about which cloud breaches they can realistically defend against.  By following these five targeted steps, security teams can greatly improve their real-time detection and response capabilities for cloud a
