A threat actor that was previously observed using an open-source network mapping tool has greatly expanded their operations to infect over 1,500 victims. Sysdig, which is tracking the cluster under the name CRYSTALRAY, said the activities have witnessed a 10x surge, adding it includes "mass scanning, exploiting multiple vulnerabilities, and placing backdoors using multiple [open-source software]

Cybersecurity researchers have shed light on a new version of a ransomware strain called HardBit that comes packaged with new obfuscation techniques to deter analysis efforts. "Unlike previous versions, HardBit Ransomware group enhanced the version 4.0 with passphrase protection," Cybereason researchers Kotaro Ogino and Koshi Oyama said in an analysis. "The passphrase needs to be provided during

In a new malware campaign, threat actors are using Google ads to target Mac users looking to download Microsoft Teams.

Ubuntu Security Notice 6896-1 - It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.

This Metasploit module exploits an authenticated administrator-level vulnerability in Atlassian Confluence, tracked as CVE-2024-21683. The vulnerability exists due to the Rhino script engine parser evaluating tainted data from uploaded text files. This facilitates arbitrary code execution. This exploit will authenticate, validate user privileges, extract the underlying host OS information, then trigger remote code execution. All versions of Confluence prior to 7.17 are affected, as are many versions up to 8.9.0.
