Cybersecurity researchers have flagged a new variant ofmalware called Chaos that'scapable of hitting misconfigured cloud deployments, marking an expansion of the botnet's targeting infrastructure. "Chaos malware is increasingly targeting misconfigured cloud deployments, expanding beyond its traditional focus on routers and edge devices," Darktrace said in a new report. Chaos was first documented by Lumen Black Lotus Labs in September 2022, describing it as a cross-platform malware capable of targeting Windows and Linux environments to run remote shell commands, drop additional modules, propagate to other hosts by brute-forcing SSH keys, mine cryptocurrency, and launch distributed denial-of-service (DDoS) attacks via HTTP, TLS, TCP, UDP, and WebSocket. The malware is assessed to be an evolution of another DDoS malware known as Kaiji  that has singled out misconfigured Docker instances.It's currently not known wh...

Until last year, cyber criminals were only targeting computers of individuals and organisations with ransomware and holding them for ransom, but then they started targeting unprotected online databases and servers around the globe for ransom as well. Earlier this year, we saw notorious incidents where tens of thousands of unprotected MongoDB and Elasticsearch databases were hacked and held for ransom in exchange of the data the hackers had stolen and deleted from the poorly configured systems. Now, cyber crooks have started targeting unprotected Hadoop Clusters and CouchDB servers as well, making the ransomware game nastier if your servers are not securely configured. Nearly 4,500 servers with the Hadoop Distributed File System (HDFS) — the primary distributed storage used by Hadoop applications — were found exposing more than 5,000 Terabytes (5.12 Petabytes) of data, according to an analysis conducted using Shodan search engine. This exposure is due to the same issue — H...
