How Malicious Actors Abuse Native Linux Tools in Their Attacks

Based on real-world attacks and our honeypots, we observed that malicious actors use a variety of enabled tools that come bundled with Linux distributions, such as curl, wget, chmod, chattr, ssh, base64, chroot, crontab, ps, and pkill, that are abused by attackers for nefarious purposes. We have seen malicious actors abusing these tools in the wild. The presence of these utilities, especially inside container environments, should be at least considered, since they provide additional avenues…

Enhancing Cloud Security by Reducing Container Images Through Distroless Techniques

Figure 1 shows that there are 96 packages installed in this image. We can also use Grype, also an increasingly popular tool, to analyze the SBOM generated by Syft to scan the original image for vulnerabilities. The extent of the risk of using Debian-based images is plain to see: The more packages there are, the larger the attack surface becomes. This also results in a bigger disk and bandwidth footprint, which has pushed many developers…

Play Ransomware Attack Playbook Similar to that of Hive, Nokoyawa

Initial Access Play’s ransomware actors commonly gain initial access through valid accounts that have been reused across multiple platforms, have previously been exposed, or were obtained through illegal means. This includes Virtual Private Network (VPN) accounts, not just domain and local accounts. Exposed RDP servers are also abused to establish a foothold. Another technique Play ransomware uses is the exploitation of the FortiOS vulnerabilities CVE-2018-13379 and CVE-2020-12812. CVE-2018-13379 is a path traversal vulnerability in the…

New Golang Ransomware Agenda Customizes Attacks

Analysis and notable features The Agenda ransomware is a 64-bit Windows PE file written in Go. Go programs are cross-platform and completely standalone, meaning they will execute properly even without a Go interpreter installed on a system. This is possible since Go statically compiles necessary libraries (packages). Upon execution, this ransomware accepts various command-line arguments that define the malware flow and functionality, as listed in the table below. Argument  Description -alter {int}  Defines the port number…

What Exposed OPA Servers Can Tell You About Your Applications

With the proper request or token, an attacker could obtain even more information about these services and look for vulnerabilities or other entry points to get into an organization’s systems. We highly recommend that companies currently leveraging OPA as their policy-as-code solution to ensure that they are not unwittingly exposing their APIs and policies online. In certain cases, companies could be using OPA without them realizing it; multiple providers for Kubernetes-managed services rely on OPA for…
