A new malware campaign leveraged two zero-day flaws in Cisco networking gear to deliver custom malware and facilitate covert data collection on target environments. Cisco Talos, which dubbed the activity  ArcaneDoor , attributed it as the handiwork of a previously undocumented sophisticated state-sponsored actor it tracks under the name UAT4356 (aka Storm-1849 by Microsoft). "UAT4356 deployed two backdoors as components of this campaign, 'Line Runner' and 'Line Dancer,' which were used collectively to conduct malicious actions on-target, which included configuration modification, reconnaissance, network traffic capture/exfiltration and potentially lateral movement," Talos  said . The intrusions, which were first detected and confirmed in early January 2024, entail the exploitation of  two vulnerabilities  - CVE-2024-20353  (CVSS score: 8.6) - Cisco Adaptive Security Appliance and Firepower Threat Defense Software Web Services Denial-of-Service Vulnerabi

Palo Alto Networks is warning that a critical flaw impacting PAN-OS software used in its GlobalProtect gateways is being actively exploited in the wild. Tracked as  CVE-2024-3400 , the issue has a CVSS score of 10.0, indicating maximum severity. "A command injection vulnerability in the GlobalProtect feature of Palo Alto Networks PAN-OS software for specific PAN-OS versions and distinct feature configurations may enable an unauthenticated attacker to execute arbitrary code with root privileges on the firewall," the company  said  in an advisory published today. The flaw impacts the following versions of PAN-OS, with fixes expected to be released on April 14, 2024 - PAN-OS < 11.1.2-h3 PAN-OS < 11.0.4-h1 PAN-OS < 10.2.9-h1 The company also said that the issue is applicable only to firewalls that have the configurations for both  GlobalProtect gateway  (Network > GlobalProtect > Gateways) and  device telemetry  (Device > Setup > Telemetry) enabled.

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday issued an emergency directive (ED 24-02) urging federal agencies to hunt for signs of compromise and enact preventive measures following the recent compromise of Microsoft's systems that led to the theft of email correspondence with the company. The attack, which  came to light  earlier this year, has been attributed to a Russian nation-state group tracked as Midnight Blizzard (aka APT29 or Cozy Bear). Last month, Microsoft revealed that the adversary managed to access some of its source code repositories but noted that there is no evidence of a breach of customer-facing systems. The emergency directive, which was originally issued privately to federal agencies on April 2, was  first reported  on by CyberScoop two days later. "The threat actor is using information initially exfiltrated from the corporate email systems, including authentication details shared between Microsoft customers and Micros

The Police of Finland (aka Poliisi) has formally accused a Chinese nation-state actor tracked as APT31 for orchestrating a cyber attack targeting the country's Parliament in 2020. The intrusion, per the authorities, is said to have occurred between fall 2020 and early 2021. The agency described the ongoing criminal probe as both demanding and time-consuming, involving extensive analysis of a "complex criminal infrastructure." The breach was  first disclosed  in December 2020, with the Finnish Security and Intelligence Service (Supo)  describing  it as a  state-backed cyber espionage operation  designed to penetrate the Parliament's information systems. "The police have previously informed that they are investigating the hacking group APT31's connections with the incident," Poliisi said. "These connections have now been confirmed by the investigation, and the police have also identified one suspect." APT31 , also called Altaire, Bronze Vin

Considering the ever-changing state of cybersecurity, it's never too late to ask yourself, "am I doing what's necessary to keep my organization's web applications secure?" The continuous evolution of technology introduces new and increasingly sophisticated threats daily, posing challenges to organizations all over the world and across the broader spectrum of industries striving to maintain reliable defenses. 2024 promises to be no exception. Threat actors continue to adapt their tactics, techniques, and procedures to exploit vulnerabilities in innovative ways, injecting malicious content into files that bypass traditional antivirus solutions and advanced, AI and ML-powered solutions alike. Therefore, organizations must assess and continually reinforce their security measures. One critical aspect that organizations often grapple with is identifying and addressing security blind spots. These are areas within the infrastructure where vulnerabilities exist but may

Two China-linked advanced persistent threat (APT) groups have been observed targeting entities and member countries affiliated with the Association of Southeast Asian Nations (ASEAN) as part of a cyber espionage campaign over the past three months. This includes the threat actor known as  Mustang Panda , which has been recently linked to  cyber attacks against Myanmar  as well as other Asian countries with a variant of the PlugX (aka Korplug) backdoor dubbed  DOPLUGS . Mustang Panda, also called Camaro Dragon, Earth Preta, and Stately Taurus, is believed to have targeted entities in Myanmar, the Philippines, Japan and Singapore, targeting them with phishing emails designed to deliver two malware packages. "Threat actors created malware for these packages on March 4-5, 2024, coinciding with the ASEAN-Australia Special Summit (March 4-6, 2024)," Palo Alto Networks Unit 42  said  in a report shared with The Hacker News. One of the malware package is a ZIP file that contains

A financially motivated threat actor called  Magnet Goblin  is swiftly adopting one-day security vulnerabilities into its arsenal in order to opportunistically breach edge devices and public-facing services and deploy malware on compromised hosts. "Threat actor group Magnet Goblin's hallmark is its ability to swiftly leverage newly disclosed vulnerabilities, particularly targeting public-facing servers and edge devices," Check Point  said . "In some cases, the deployment of the exploits is within 1 day after a [proof-of-concept] is published, significantly increasing the threat level posed by this actor." Attacks mounted by the adversary have leveraged unpatched Ivanti Connect Secure VPN, Magento, Qlik Sense, and possibly Apache ActiveMQ servers as an initial infection vector to gain unauthorized access. The group is said to be active since at least January 2022. A successful exploitation is followed by the deployment of a cross-platform remote access trojan (RAT) dubbed Nerbian

The notorious Lazarus Group actors exploited a recently patched privilege escalation flaw in the Windows Kernel as a zero-day to obtain kernel-level access and disable security software on compromised hosts. The vulnerability in question is  CVE-2024-21338  (CVSS score: 7.8), which can permit an attacker to gain SYSTEM privileges. It was resolved by Microsoft earlier this month as part of  Patch Tuesday updates . "To exploit this vulnerability, an attacker would first have to log on to the system," Microsoft  said . "An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system." While there were no indications of active exploitation of CVE-2024-21338 at the time of the release of the updates, Redmond on Wednesday revised its "Exploitability assessment" for the flaw to "Exploitation Detected."  It's currently not clear when the attacks took place, but the vulnerability

Meta Platforms said it took a series of steps to curtail malicious activity from eight different firms based in Italy, Spain, and the United Arab Emirates (U.A.E.) operating in the surveillance-for-hire industry. The findings are part of its  Adversarial Threat Report  for the fourth quarter of 2023. The spyware targeted iOS, Android, and Windows devices. "Their various malware included capabilities to collect and access device information, location, photos and media, contacts, calendar, email, SMS, social media, and messaging apps, and enable microphone,camera, and screenshot functionality," the company said. The eight companies are Cy4Gate/ELT Group, RCS Labs, IPS Intelligence, Variston IT, TrueL IT, Protect Electronic Systems, Negg Group, and Mollitiam Industries. These firms, per Meta, also engaged in scraping, social engineering, and phishing activity that targeted a wide range of platforms such as Facebook, Instagram, X (formerly Twitter), YouTube, Skype, GitHub, R

Microsoft on Wednesday acknowledged that a newly disclosed critical security flaw in Exchange Server has been actively exploited in the wild, a day after it released fixes for the vulnerability as part of its  Patch Tuesday updates . Tracked as  CVE-2024-21410  (CVSS score: 9.8), the issue has been described as a case of privilege escalation impacting the Exchange Server. "An attacker could target an NTLM client such as Outlook with an NTLM credentials-leaking type vulnerability," the company  said  in an advisory published this week. "The leaked credentials can then be relayed against the Exchange server to gain privileges as the victim client and to perform operations on the Exchange server on the victim's behalf." Successful exploitation of the flaw could permit an attacker to relay a user's leaked Net-NTLMv2 hash against a susceptible Exchange Server and authenticate as the user, Redmond added. The tech giant, in an update to its bulletin, revised

A newly disclosed security flaw in the Microsoft Defender SmartScreen has been exploited as a zero-day by an advanced persistent threat actor called  Water Hydra  (aka DarkCasino) targeting financial market traders. Trend Micro, which began tracking the campaign in late December 2023, said it entails the exploitation of CVE-2024-21412, a security bypass vulnerability related to Internet Shortcut Files (.URL).  "In this attack chain, the threat actor leveraged CVE-2024-21412 to bypass Microsoft Defender SmartScreen and infect victims with the DarkMe malware," the cybersecurity firm  said  in a Tuesday report. Microsoft, which  addressed  the flaw in its February Patch Tuesday update, said an unauthenticated attacker could exploit the flaw by sending the targeted user a specially crafted file in order to bypass displayed security checks. However, successful exploitation banks on the prerequisite that the threat actor convinces the victim to click on the file link to view

Microsoft has released patches to address  73 security flaws  spanning its software lineup as part of its Patch Tuesday updates for February 2024, including two zero-days that have come under active exploitation. Of the 73 vulnerabilities, 5 are rated Critical, 65 are rated Important, and three and rated Moderate in severity. This is in addition to  24 flaws  that have been fixed in the Chromium-based Edge browser since the release of the January 2024 Patch Tuesday updates . The two flaws that are listed as under active attack at the time of release are below - CVE-2024-21351  (CVSS score: 7.6) - Windows SmartScreen Security Feature Bypass Vulnerability CVE-2024-21412  (CVSS score: 8.1) - Internet Shortcut Files Security Feature Bypass Vulnerability "The vulnerability allows a malicious actor to inject code into  SmartScreen  and potentially gain code execution, which could potentially lead to some data exposure, lack of system availability, or both," Microsoft said a

Fortinet has disclosed a new critical security flaw in FortiOS SSL VPN that it said is likely being exploited in the wild. The vulnerability,  CVE-2024-21762  (CVSS score: 9.6), allows for the execution of arbitrary code and commands. "An out-of-bounds write vulnerability [CWE-787] in FortiOS may allow a remote unauthenticated attacker to execute arbitrary code or command via specially crafted HTTP requests," the company  said  in a bulletin released Thursday. It further acknowledged that the issue is "potentially being exploited in the wild," without giving additional specifics about how it's being weaponized and by whom. The following versions are impacted by the vulnerability. It's worth noting that FortiOS 7.6 is not affected. FortiOS 7.4 (versions 7.4.0 through 7.4.2) - Upgrade to 7.4.3 or above FortiOS 7.2 (versions 7.2.0 through 7.2.6) - Upgrade to 7.2.7 or above FortiOS 7.0 (versions 7.0.0 through 7.0.13) - Upgrade to 7.0.14 or above Forti

A coalition of dozens of countries, including France, the U.K., and the U.S., along with tech companies such as Google, MDSec, Meta, and Microsoft, have signed a joint agreement to curb the abuse of commercial spyware to commit human rights abuses. The initiative, dubbed the  Pall Mall Process , aims to tackle the proliferation and irresponsible use of commercial cyber intrusion tools by establishing guiding principles and policy options for States, industry, and civil society in relation to the development, facilitation, purchase, and use of such tools. The declaration stated that "uncontrolled dissemination" of spyware offerings contributes to "unintentional escalation in cyberspace," noting it poses risks to cyber stability, human rights, national security, and digital security. "Where these tools are used maliciously, attacks can access victims' devices, listen to calls, obtain photos and remotely operate a camera and microphone via 'zero-click&
