Cybersecurity researchers have uncovered three security weaknesses in Microsoft's Azure Data Factory Apache Airflow integration that, if successfully exploited, could have allowed an attacker to gain the ability to conduct various covert actions, including data exfiltration and malware deployment. "Exploiting these flaws could allow attackers to gain persistent access as shadow administrators over the entire Airflow Azure Kubernetes Service (AKS) cluster," Palo Alto Networks Unit 42 said in an analysis published earlier this month. The vulnerabilities, albeit classified as low severity by Microsoft, are listed below - Misconfigured Kubernetes RBAC in Airflow cluster Misconfigured secret handling of Azure's internal Geneva service, and Weak authentication for Geneva Besides obtaining unauthorized access, the attacker could take advantage of the flaws in the Geneva service to potentially tamper with log data or send fake logs to avoid raising suspicion when c...

The United States Department of Health and Human Services' (HHS) Office for Civil Rights (OCR) has proposed new cybersecurity requirements for healthcare organizations with an aim to safeguard patients' data against potential cyber attacks. The proposal, which seeks to modify the Health Insurance Portability and Accountability Act (HIPAA) of 1996, is part of a broader initiative to bolster the cybersecurity of critical infrastructure, the OCR said. The rule is designed to strengthen protections for electronic protected health information (ePHI) by updating the HIPAA Security Rule's standards to "better address ever-increasing cybersecurity threats to the healthcare sector." To that end, the proposal, among other things, requires organizations to conduct a review of the technology asset inventory and network map, identify potential vulnerabilities that could pose a threat to electronic information systems, and establish procedures to restore the loss of certa...

The vulnerability (CVE-2024-3393, CVSS score: 8.7) only affects firewalls that have the DNS Security logging enabled. The company said it's aware of...

News has been making headlines over the weekend of the extensive attack campaign targeting browser extensions and injecting them with malicious code to steal user credentials. Currently, over 25 extensions, with an install base of over two million users, have been found to be compromised, and customers are now working to figure out their exposure (LayerX, one of the companies involved in protecting against malicious extensions is offering a complimentary service to audit and remediate organizations' exposure - to sign-up click here ). While this is not the first attack to target browser extensions, the scope and sophistication of this campaign are a significant step up in terms of the threats posed by browser extensions and the risks they pose to organizations. Now that details of the attack have been publicized, users and organizations need to assess their risk exposure to this attack and to browser extensions in general. This article is aimed at helping organizations understand t...

A new attack campaign has targeted known Chrome browser extensions, leading to at least 35 extensions being compromised and exposing over 2.6 million users to data exposure and credential theft. The attack targeted publishers of browser extensions on the Chrome Web Store via a phishing campaign and used their access permissions to insert malicious code into legitimate extensions in order to steal cookies and user access tokens. The first company to shed light the campaign was cybersecurity firm Cyberhaven, one of whose employees was targeted by a phishing attack on December 24, allowing the threat actors to publish a malicious version of the extension. On December 27, Cyberhaven disclosed that a threat actor compromised its browser extension and injected malicious code to communicate with an external command-and-control (C&C) server located on the domain cyberhavenext[.]pro, download additional configuration files, and exfiltrate user data. The phishing email, which purported...

A high-severity flaw impacting select Four-Faith industrial routers has come under active exploitation in the wild, according to new findings from VulnCheck. The vulnerability, tracked as CVE-2024-12856 (CVSS score: 7.2), has been described as an operating system (OS) command injection bug affecting router models F3x24 and F3x36. The severity of the shortcoming is lower due to the fact that it only works if the remote attacker is able to successfully authenticate themselves. However, if the default credentials associated with the routers have not been changed, it could result in unauthenticated OS command execution. In the attack detailed by VulnCheck, the unknown threat actors have been found to leverage the router's default credentials to trigger exploitation of CVE-2024-12856 and launch a reverse shell for persistent remote access. The exploitation attempt originated from the IP address 178.215.238[.]91 , which has been previously used in connection with attacks seeking to...

North Korean threat actors behind the ongoing Contagious Interview campaign have been observed dropping a new JavaScript malware called OtterCookie . Contagious Interview (aka DeceptiveDevelopment ) refers to a persistent attack campaign that employs social engineering lures, with the hacking crew often posing as recruiters to trick individuals looking for potential job opportunities into downloading malware under the guise of an interview process. This involves distributing malware-laced videoconferencing apps or npm packages either hosted on GitHub or the official package registry, paving the way for the deployment of malware such as BeaverTail and InvisibleFerret. Palo Alto Networks Unit 42, which first exposed the activity in November 2023, is tracking the cluster under the moniker CL-STA-0240. It's also referred to as Famous Chollima and Tenacious Pungsan. In September 2024, Singaporean cybersecurity company Group-IB documented the first major revision to the attack c...

The threat actor known as Cloud Atlas has been observed using a previously undocumented malware called VBCloud as part of its cyber attack campaigns targeting "several dozen users" in 2024. "Victims get infected via phishing emails containing a malicious document that exploits a vulnerability in the formula editor (CVE-2018-0802) to download and execute malware code," Kaspersky researcher Oleg Kupreev said in an analysis published this week. More than 80% of the targets were located in Russia. A lesser number of victims have been reported from Belarus, Canada, Moldova, Israel, Kyrgyzstan, Turkey, and Vietnam. Also referred to as Clean Ursa, Inception, Oxygen, and Red October, Cloud Atlas is an unattributed threat activity cluster that has been active since 2014. In December 2022, the group was linked to cyber attacks aimed at Russia, Belarus, and Transnistria that deployed a PowerShell-based backdoor called PowerShower. Then exactly a year later, Russian cy...

Palo Alto Networks has disclosed a high-severity vulnerability impacting PAN-OS software that could cause a denial-of-service (DoS) condition on susceptible devices. The flaw, tracked as CVE-2024-3393 (CVSS score: 8.7), impacts PAN-OS versions 10.X and 11.X, as well as Prisma Access running PAN-OS versions 10.2.8 and later or prior to 11.2.3. It has been addressed in PAN-OS 10.1.14-h8, PAN-OS 10.2.10-h12, PAN-OS 11.1.5, PAN-OS 11.2.3, and all later PAN-OS versions. "A denial-of-service vulnerability in the DNS Security feature of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to send a malicious packet through the data plane of the firewall that reboots the firewall," the company said in a Friday advisory. "Repeated attempts to trigger this condition will cause the firewall to enter maintenance mode." Palo Alto Networks said it discovered the flaw in production use, and that it's aware of customers "experiencing this denial-of-...
