The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a security flaw impacting the Linux kernel to the Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as CVE-2024-1086 (CVSS score: 7.8), the high-severity issue relates to a use-after-free bug in the netfilter component that permits a local attacker to elevate privileges from a regular user to root and possibly execute arbitrary code. "Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation," CISA said. Netfilter is a framework provided by the Linux kernel that allows the implementation of various network-related operations in the form of custom handlers to facilitate packet filtering, network address translation, and port translation. The vulnerability was addressed in January 2024. That said, the exact nature of the attacks exploiting the fla...

Cloudflare on Thursday said it took steps to disrupt a month-long phishing campaign orchestrated by a Russia-aligned threat actor called FlyingYeti targeting Ukraine. "The FlyingYeti campaign capitalized on anxiety over the potential loss of access to housing and utilities by enticing targets to open malicious files via debt-themed lures," Cloudflare's threat intelligence team Cloudforce One said in a new report published today. "If opened, the files would result in infection with the PowerShell malware known as COOKBOX, allowing FlyingYeti to support follow-on objectives, such as installation of additional payloads and control over the victim's system." FlyingYeti is the denomination used by the web infrastructure company to track an activity cluster that the Computer Emergency Response Team of Ukraine (CERT-UA) is tracking under the moniker UAC-0149. Previous attacks disclosed by the cybersecurity agency have involved the use of malicious attachme...

A previously undocumented cyber espionage-focused threat actor named LilacSquid has been linked to targeted attacks spanning various sectors in the United States (U.S.), Europe, and Asia as part of a data theft campaign since at least 2021. "The campaign is geared toward establishing long-term access to compromised victim organizations to enable LilacSquid to siphon data of interest to attacker-controlled servers," Cisco Talos researcher Asheer Malhotra said in a new technical report published today. Targets include information technology organizations building software for the research and industrial sectors in the U.S, energy companies in Europe, and the pharmaceutical sector in Asia, indicating a broad victimology footprint. Attack chains are known to exploit either publicly known vulnerabilities to breach internet-facing application servers or make use of compromised remote desktop protocol (RDP) credentials to deliver a mix of open-source tools and custom malware. ...

The threat actors behind the RedTail cryptocurrency mining malware have added a recently disclosed security flaw impacting Palo Alto Networks firewalls to its exploit arsenal. The addition of the PAN-OS vulnerability to its toolkit has been complemented by updates to the malware, which now incorporates new anti-analysis techniques, according to findings from web infrastructure and security company Akamai. "The attackers have taken a step forward by employing private crypto-mining pools for greater control over mining outcomes despite the increased operational and financial costs," security researchers Ryan Barnett, Stiv Kupchik, and Maxim Zavodchik said in a technical report shared with The Hacker News. The infection sequence discovered by Akamai exploits a now-patched vulnerability in PAN-OS tracked as CVE-2024-3400 (CVSS score: 10.0) that could allow an unauthenticated attacker to execute arbitrary code with root privileges on the firewall. A successful exploitatio...

Cybersecurity researchers have warned that multiple high-severity security vulnerabilities in WordPress plugins are being actively exploited by threat actors to create rogue administrator accounts for follow-on exploitation. "These vulnerabilities are found in various WordPress plugins and are prone to unauthenticated stored cross-site scripting (XSS) attacks due to inadequate input sanitization and output escaping, making it possible for attackers to inject malicious scripts," Fastly researchers Simran Khalsa, Xavier Stevens, and Matthew Mathur said . The security flaws in question are listed below - CVE-2023-6961 (CVSS score: 7.2) - Unauthenticated Stored Cross-Site Scripting in WP Meta SEO <= 4.5.12 CVE-2023-40000 (CVSS score: 8.3) - Unauthenticated Stored Cross-Site Scripting in LiteSpeed Cache <= 5.7 CVE-2024-2194 (CVSS score: 7.2) - Unauthenticated Stored Cross-Site Scripting in WP Statistics <= 14.5 Attack chains exploiting the flaws involve inject...

Security leaders are in a tricky position trying to discern how much new AI-driven cybersecurity tools could actually benefit a security operations center (SOC). The hype about generative AI is still everywhere, but security teams have to live in reality. They face constantly incoming alerts from endpoint security platforms, SIEM tools, and phishing emails reported by internal users. Security teams also face an acute talent shortage.  In this guide, we'll lay out practical steps organizations can take to automate more of their processes and build an autonomous SOC strategy . This should address the acute talent shortage in security teams, by employing artificial intelligence and machine learning with a variety of techniques, these systems simulate the decision-making and investigative processes of human analysts. First, we'll define objectives for an autonomous SOC strategy and then consider key processes that could be automated. Next, we'll consider different AI and automation ...

Europol on Thursday said it shut down the infrastructure associated with several malware loader operations such as IcedID, SystemBC, PikaBot, SmokeLoader, Bumblebee, and TrickBot as part of a coordinated law enforcement effort codenamed Operation Endgame . "The actions focused on disrupting criminal services through arresting High Value Targets, taking down the criminal infrastructures and freezing illegal proceeds," Europol said in a statement. "The malware [...] facilitated attacks with ransomware and other malicious software." The action, which took place between May 27 and May 29, has resulted in the dismantling of over 100 servers worldwide and the arrest of four people, one in Armenia three in Ukraine , following searches across 16 locations in Armenia, the Netherlands, Portugal, and Ukraine. The servers, according to Europol, were located in Bulgaria, Canada, Germany, Lithuania, the Netherlands, Romania, Switzerland, Ukraine, the United Kingdom, and the...
