Ransomware Recruitment Efforts Following Law Enforcement Disruption
Ransomware Recruitment Efforts Following Law Enforcement Disruption
In late 2023 and early 2024, the ransomware ecosystem experienced repeated disruption of its most prolific Ransomware-as-a-Service (RaaS) groups at the hands of international Law Enforcement (LE). Alphv’s dark web data leak site was seized, then unseized, then re-seized in a December 2023 law enforcement operation that seemingly failed to deter the group – until AlphV ultimately claimed to disband via an apparent exit scam, immediately following a high-profile attack against Change Healthcare in March 2024. LockBit experienced a far more dramatic and well-marketed disruption, “Operation Cronos,” in February 2024, leading to the compromise of its infrastructure, internal operational details, and data. While LockBit has ostensibly continued operations, its highly publicized disruption raises the question of whether the group will be able to continue operating and attracting affiliates at the level they once enjoyed.

Understanding and Responding to Distributed Denial-Of-Service Attacks
Understanding and Responding to Distributed Denial-Of-Service Attacks
This joint guide, Understanding and Responding to Distributed Denial-Of-Service Attacks, addresses the specific needs and challenges faced by organizations in defending against DDoS attacks. The guidance now includes detailed insight into three different types of DDoS techniques: Volumetric, attacks aiming to consume available bandwidth. Protocol, attacks which exploit vulnerabilities in network protocols. * Application, attacks targeting vulnerabilities in specific applications or running services.

Huntress recently detected interesting activity on an endpoint; a threat actor was attempting to establish a foothold on an endpoint by using commands issued via MSSQL to upload a reverse shell accessible from the web server. All attempts were obviated by MAV and process detections, but boy-howdy, did they try!

Loop DoS: New Denial-of-Service attack targets application-layer protocols
Loop DoS: New Denial-of-Service attack targets application-layer protocols
A new Denial-of-Service (DoS) attack targets application-layer protocols that draw on the User Datagram Protocol (UDP) for end-to-end communication. The vulnerability affects both legacy and contemporary protocols. Discovered by Christian Rossow and Yepeng Pan, the attack puts an estimated 300,000 Internet hosts and their networks at risk.

Two Bytes is Plenty: FortiGate RCE with CVE-2024-21762
Two Bytes is Plenty: FortiGate RCE with CVE-2024-21762
Early this February, Fortinet released an advisory for an "out-of-bounds write vulnerability" that could lead to remote code execution. The issue affected the SSL VPN component of their FortiGate network appliance and was potentially already being exploited in the wild. In this post we detail the steps we took to identify the patched vulnerability and produce a working exploit.

What a Cluster: Local Volumes Vulnerability in Kubernetes
What a Cluster: Local Volumes Vulnerability in Kubernetes
  • Akamai security researcher Tomer Peled recently discovered a high-severity vulnerability in Kubernetes that was assigned CVE-2023-5528 with a CVSS score of 7.2. The vulnerability allows remote code execution with SYSTEM privileges on all Windows endpoints within a Kubernetes cluster. To exploit this vulnerability, the attacker needs to apply malicious YAML files on the cluster. This vulnerability can lead to full takeover on all Windows nodes in a cluster. This vulnerability can be exploited on default installations of Kubernetes (earlier than version 1.28.4), and was tested against both on-prem deployments and Azure Kubernetes Service. In this blog post, we provide a proof-of-concept YAML file as well as an Open Policy Agent (OPA) rule for blocking this vulnerability.
