The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday warned that multiple nation-state actors are exploiting security flaws in Fortinet FortiOS SSL-VPN and Zoho ManageEngine ServiceDesk Plus to gain unauthorized access and establish persistence on compromised systems. "Nation-state advanced persistent threat (APT) actors exploited CVE-2022-47966 to gain unauthorized access to a public-facing application (Zoho ManageEngine ServiceDesk Plus), establish persistence, and move laterally through the network," according to a joint alert published by the agency, alongside Federal Bureau of Investigation (FBI), and Cyber National Mission Force (CNMF). The identities of the threat groups behind the attacks have not been disclosed, although the U.S. Cyber Command (USCYBERCOM) hinted at the involvement of Iranian nation-state crews. The findings are based on an incident response engagement conducted by CISA at nn unnamed aeronautical sector organization f...

  Cybersecurity researchers have disclosed two high-severity security flaws in the Ubuntu kernel that could pave the way for local privilege escalation attacks. Cloud security firm Wiz, in a report shared with The Hacker News, said the easy-to-exploit shortcomings have the potential to impact 40% of Ubuntu users. "The impacted Ubuntu versions are prevalent in the cloud as they serve as the default operating systems for multiple [cloud service providers]," security researchers Sagi Tzadik and Shir Tamari said. The vulnerabilities – tracked as CVE-2023-32629 and 2023-2640 (CVSS scores: 7.8) and dubbed  GameOver(lay)  – are present in a module called OverlayFS and arise as a result of inadequate permissions checks in certain scenarios, enabling a local attacker to gain elevated privileges. Overlay Filesystem refers to a union mount file system that makes it possible to combine multiple directory trees or file systems into a single, unified files...

  A previously undocumented Windows-based information stealer called  ThirdEye  has been discovered in the wild with capabilities to harvest sensitive data from infected hosts. Fortinet FortiGuard Labs, which made the discovery, said it found the malware in an executable that masqueraded as a PDF file with a Russian name "CMK Правила оформления больничных листов.pdf.exe," which translates to "CMK Rules for issuing sick leaves.pdf.exe." The arrival vector for the malware is presently unknown, although the nature of the lure points to it being used in a phishing campaign. The very first ThirdEye sample was uploaded to VirusTotal on April 4, 2023, with relatively fewer features. The evolving stealer, like other malware families of its kind, is equipped to gather system metadata, including BIOS release date and vendor, total/free disk space on the C drive, currently running processes, register usernames, and volume information. The amassed d...

VMware has flagged that a recently patched critical command injection vulnerability in Aria Operations for Networks (formerly vRealize Network Insight) has come under active exploitation in the wild. The flaw, tracked as  CVE-2023-20887 , could allow a malicious actor with network access to the product to perform a command injection attack, resulting in remote code execution. It impacts VMware Aria Operations Networks versions 6.x, with fixes released in versions 6.2, 6.3, 6.4, 6.5.1, 6.6, 6.7, 6.8, 6.9, and 6.10 on June 7, 2023. Now according to an update shared by the virtualization services provider on June 20, the flaw has been weaponized in real-world attacks, although the exact specifics are unknown as yet. "VMware has confirmed that exploitation of CVE-2023-20887 has occurred in the wild," the company noted. Data gathered by threat intelligence firm GreyNoise shows active exploitation of the flaw from two different IP addresses located in the Netherl...

  A vulnerability has been discovered in Google Chrome, which could allow for arbitrary code execution. Google Chrome is a web browser used to access the internet. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. THREAT INTELLIGENCE: Google is aware that an exploit for CVE-2023-3079 exists in the wild. SYSTEMS AFFECTED: Google Chrome versions prior to 114.0.5735.110 for Windows. Google Chrome versions prior to 114.0.5735.106 for Mac and Linux. RISK: Government: Large and medium government entities HIGH Small government MEDIUM Businesses: Large and medium bu...

  Apple has recently addressed a vulnerability that lets attackers with root privileges bypass System Integrity Protection (SIP) to install "undeletable" malware and access the victim's private data by circumventing Transparency, Consent, and Control (TCC) security checks. Discovered and reported to Apple by a team of Microsoft security researchers, the flaw (dubbed  Migraine ) is now tracked as CVE-2023-32369. Apple has patched the vulnerability in security updates for macOS Ventura 13.4, macOS Monterey 12.6.6, and macOS Big Sur 11.7.7, released two weeks ago, on May 18. System Integrity Protection (SIP), also known as 'rootless,' is a macOS security mechanism that prevents potentially malicious software from altering certain folders and files by imposing restrictions on the root user account and its capabilities within protected areas of the operating system. SIP operates under the principle that only processes signed by Apple or those possessin...
