Moby is an open source container framework developed by Docker Inc. that is distributed as Docker Engine, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (dockerd), which is developed as [moby/moby](https://github.com/moby/moby) is commonly referred to as Docker, or Docker Engine. Firewalld is a daemon used by some Linux distributions to provide a dynamically managed firewall. When Firewalld is running, Docker uses its iptables backend to create rules, including rules to isolate containers in one bridge network from containers in other bridge networks. ### Impact The iptables rules created by Docker are removed when firewalld is reloaded using, for example "firewall-cmd --reload", "killall -HUP firewalld", or "systemctl reload firewalld". When that happens, Docker must re-create the rules. However, in affected versions of Docker, the iptables rules that isolate containers in different bridge networks from each other are not re-c...

Darktrace uncovers the first exploit of a critical SAP NetWeaver vulnerability (CVE-2025-31324) to deploy Auto-Color backdoor malware. Learn how this evasive Linux RAT targets systems for remote code execution and how AI-powered defence thwarts multi-stage attacks.

International law enforcement agencies, including the FBI and Europol, have successfully seized the infrastructure of the notorious BlackSuit ransomware gang in Operation Checkmate. This article details the takedown, BlackSuit's origins, and the ongoing fight against evolving cyber threats.

AI malware is becoming less of a gimmick, with features that meet or exceed what traditional human-developed malware typically can do.

Threat hunters have disclosed two different malware campaigns that have targeted vulnerabilities and misconfigurations across cloud environments to deliver cryptocurrency miners. The threat activity clusters have been codenamed Soco404 and Koske by cloud security firms Wiz and Aqua, respectively. Soco404 "targets both Linux and Windows systems, deploying platform-specific malware," Wiz

Cisco Talos Incident Response (Talos IR) recently observed attacks by Chaos, a relatively new ransomware-as-a-service (RaaS) group conducting big-game hunting and double extortion attacks.

FBI warns of Interlock ransomware using unique tactics to hit businesses and critical infrastructure with double extortion.

Cryptominer campaign runs for years using legit sites to spread malware, targeting Linux systems through known bugs and avoiding detection.

Cybersecurity researchers have discovered a new campaign that exploits a known security flaw impacting Apache HTTP Server to deliver a cryptocurrency miner called Linuxsys. The vulnerability in question is CVE-2021-41773 (CVSS score: 7.5), a high-severity path traversal vulnerability in Apache HTTP Server version 2.4.49 that could result in remote code execution.
