Even as cyber threats become increasingly sophisticated, the number one attack vector for unauthorized access remains phished credentials (Verizon DBIR, 2024). Solving this problem resolves over 80% of your corporate risk, and a solution is possible.  However, most tools available on the market today cannot offer a complete defense against this attack vector because they were architected to

Cybersecurity researchers have uncovered a new malware campaign targeting Linux environments to conduct illicit cryptocurrency mining. The activity, which specifically singles out the Oracle Weblogic server, is designed to deliver malware dubbed Hadooken, according to cloud security firm Aqua. "When Hadooken is executed, it drops a Tsunami malware and deploys a crypto miner," security researcher

A technique to abuse Microsoft's built-in source code editor has finally made it into the wild, thanks to China's Mustang Panda APT.

An attacker is using the tool to deploy a cryptominer and the Tsunami DDoS bot on compromised systems.

A June report from CyberSeek found that there are only enough skilled workers to fill 85 percent of cybersecurity jobs in America.

This Metasploit module exploits a Remote Code Execution vulnerability in the BigUp plugin of SPIP. The vulnerability lies in the lister_fichiers_par_champs function, which is triggered when the bigup_retrouver_fichiers parameter is set to any value. By exploiting the improper handling of multipart form data in file uploads, an attacker can inject and execute arbitrary PHP code on the target server. This critical vulnerability affects all versions of SPIP from 4.0 up to and including 4.3.1, 4.2.15, and 4.1.17. It allows unauthenticated users to execute arbitrary code remotely via the public interface. The vulnerability has been patched in versions 4.3.2, 4.2.16, and 4.1.18.

This Metasploit module creates a RAR file that exploits CVE-2022-30333, which is a path-traversal vulnerability in unRAR that can extract an arbitrary file to an arbitrary location on a Linux system. UnRAR fixed this vulnerability in version 6.12 (open source version 6.1.7). The core issue is that when a symbolic link is unRARed, Windows symbolic links are not properly validated on Linux systems and can therefore write a symbolic link that points anywhere on the filesystem. If a second file in the archive has the same name, it will be written to the symbolic link path.

Debian Linux Security Advisory 5768-1 - Security issues were discovered in Chromium which could result in the execution of arbitrary code, denial of service, or information disclosure.

Ubuntu Security Notice 7006-1 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 7005-1 - Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.
