Google has patched CVE-2024-36971, a high-severity zero-day kernel vulnerability in Android, which has been exploited in targeted attacks. The vulnerability, discovered by Google’s Clément Lecigne, allows for remote code execution with system execution privileges due to a use-after-free condition. The August 2024 security update addresses this zero-day alongside over 40 other vulnerabilities, including critical issues in the framework, system, Qualcomm, Arm, Imagination Technologies, and MediaTek components.
A critical zero-day vulnerability in Apache OFBiz, tracked as CVE-2024-38856, has been discovered, allowing unauthenticated attackers to execute arbitrary code remotely. The flaw, with a CVSS score of 9.8, affects all versions of Apache OFBiz up to and including 18.12.14. It was identified by SonicWall’s Capture Labs threat research team, stemming from a flaw in the override view functionality that exposes critical endpoints to specially crafted requests.
Hunters International, a ransomware group, has introduced a new C# remote access trojan (RAT) named SharpRhino, targeting IT professionals to breach corporate networks. Discovered by Quorum Cyber, SharpRhino is distributed via a typosquatting site that impersonates the legitimate Angry IP Scanner website. The malware, disguised as a digitally signed installer, facilitates initial infection, privilege escalation, and ransomware deployment by executing PowerShell commands and modifying the Windows registry.
North Korean hackers have intensified their cyber operations, targeting South Korea’s construction and machinery sectors through sophisticated watering hole and supply chain attacks. Exploiting VPN software updates, these attackers have embedded malware to infiltrate networks and steal sensitive intellectual property and trade secrets. The primary actors, Kimsuky and Andariel, are linked to North Korea's Reconnaissance General Bureau and are believed to be supporting Pyongyang’s industrial expansion initiatives.
A recent cyber attack has seen Russian APT group Fighting Ursa using a deceptive "car for sale" advertisement to distribute HeadLace backdoor malware, targeting Windows systems since March 2024. The attackers exploited Webhook.site , a legitimate URL service, to deliver a multi-stage infection chain. Victims clicking on the ad were directed to a malicious HTML page that offered a ZIP file disguised as an image. The ZIP file contained a disguised executable that, when run, deployed the HeadLace backdoor via a DLL.
On August 5, Le Parisien reported a ransomware attack that targeted IT systems used by approximately 40 French museums, including the Grand Palais. Detected on the night of August 3-4, the attack was discovered by the Grand Palais’ IT director who found unusual activity linked to the ransomware. The malware encrypted parts of the museums' systems and demanded a cryptocurrency ransom, threatening to leak data if the ransom was not paid within 48 hours.
Calibrated Healthcare, LLC, based in California, recently reported a data breach that has exposed sensitive patient information, including names, Social Security numbers, medical diagnoses, and health insurance details. Discovered on February 26, 2024, the breach involved unauthorized access to the company’s network between February 25 and February 26, 2024. Calibrated has since notified affected individuals and is offering 12 to 24 months of free credit monitoring and identity protection services.
