Ivanti has warned that three new security vulnerabilities impacting its Cloud Service Appliance (CSA) have come under active exploitation in the wild. The zero-day flaws are being weaponized in conjunction with another flaw in CSA that the company patched last month, the Utah-based software services provider said. Successful exploitation of these vulnerabilities could allow an authenticated attacker with admin privileges to bypass restrictions, run arbitrary SQL statements, or obtain remote code execution. "We are aware of a limited number of customers running CSA 4.6 patch 518 and prior who have been exploited when CVE-2024-9379, CVE-2024-9380, or CVE-2024-9381 are chained with CVE-2024-8963," the company said . There is no evidence of exploitation against customer environments running CSA 5.0. A brief description of the three shortcomings is as follows - CVE-2024-9379 (CVSS score: 6.5) - SQL injection in the admin web console of Ivanti CSA before version 5.0.2 all

Cybersecurity researchers are warning about active exploitation attempts targeting a newly disclosed security flaw in Synacor's Zimbra Collaboration. Enterprise security firm Proofpoint said it began observing the activity starting September 28, 2024. The attacks seek to exploit CVE-2024-45519 , a severe security flaw in Zimbra's postjournal service that could enable unauthenticated attackers to execute arbitrary commands on affected installations. "The emails spoofing Gmail were sent to bogus addresses in the CC fields in an attempt for Zimbra servers to parse and execute them as commands," Proofpoint said in a series of posts on X. "The addresses contained Base64 strings that are executed with the sh utility." The critical issue was addressed by Zimbra in versions 8.8.15 Patch 46, 9.0.0 Patch 41, 10.0.9, and 10.1.1 released on September 4, 2024. A security researcher named lebr0nli (Alan Li) has been credited with discovering and reporting the short

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,

Security Orchestration, Automation, and Response (SOAR) was introduced with the promise of revolutionizing Security Operations Centers (SOCs) through automation, reducing manual workloads and enhancing efficiency. However, despite three generations of technology and 10 years of advancements, SOAR hasn't fully delivered on its potential, leaving SOCs still grappling with many of the same challenges. Enter Agentic AI—a new approach that could finally fulfill the SOC's long-awaited vision, providing a more dynamic and adaptive solution to automate SOC operations effectively. Three Generations of SOAR – Still Falling Short SOAR emerged in the mid-2010s with companies like PhantomCyber, Demisto, and Swimlane, promising to automate SOC tasks, improve productivity, and shorten response times. Despite these ambitions, SOAR found its greatest success in automating generalized tasks like threat intel propagation, rather than core threat detection, investigation, and response (TDIR) workloads.

Imagine this... You arrive at work to a chaotic scene. Systems are down, panic is in the air. The culprit? Not a rogue virus, but a compromised identity. The attacker is inside your walls, masquerading as a trusted user. This isn't a horror movie, it's the new reality of cybercrime. The question is, are you prepared? Traditional incident response plans are like old maps in a new world. They focus on malware and network breaches, but today's criminals are after your identities. Stolen credentials, and weak access points - these are the keys to your kingdom. While there's a playbook for handling malware outbreaks, the 'identity' chapter is often missing. Organizations struggle to identify compromised accounts and stop attackers from moving laterally within their systems. The result? A breach that spirals out of control, causing massive damage. The Solution: An Identity-Focused Incident Response Playbook This isn't just another security buzzword, it'

Malicious actors are likely leveraging publicly available proof-of-concept (PoC) exploits for recently disclosed security flaws in Progress Software WhatsUp Gold to conduct opportunistic attacks. The activity is said to have commenced on August 30, 2024, a mere five hours after a PoC was released for CVE-2024-6670 (CVSS score: 9.8) by security researcher Sina Kheirkhah of the Summoning Team, who is also credited with discovering and reporting CVE-2024-6671 (CVSS scores: 9.8). Both the critical vulnerabilities, which allow an unauthenticated attacker to retrieve a user's encrypted password, were patched by Progress in mid-August 2024. "The timeline of events suggests that despite the availability of patches, some organizations were unable to apply them quickly, leading to incidents almost immediately following the PoC's publication," Trend Micro researchers Hitomi Kimura and Maria Emreen Viray said in a Thursday analysis. The attacks observed by the cybersec

The threat actor known as CosmicBeetle has debuted a new custom ransomware strain called ScRansom in attacks targeting small- and medium-sized businesses (SMBs) in Europe, Asia, Africa, and South America, while also likely working as an affiliate for RansomHub . "CosmicBeetle replaced its previously deployed ransomware, Scarab, with ScRansom, which is continually improved," ESET researcher Jakub Souček said in a new analysis published today. "While not being top notch, the threat actor is able to compromise interesting targets." Targets of ScRansom attacks span manufacturing, pharmaceuticals, legal, education, healthcare, technology, hospitality, leisure, financial services, and regional government sectors. CosmicBeetle is best known for a malicious toolset called Spacecolon that was previously identified as used for delivering the Scarab ransomware across victim organizations globally. Also known as NONAME, the adversary has a track record of experimenting w

Threat actors linked to the RansomHub ransomware group encrypted and exfiltrated data from at least 210 victims since its inception in February 2024, the U.S. government said. The victims span various sectors, including water and wastewater, information technology, government services and facilities, healthcare and public health, emergency services, food and agriculture, financial services, commercial facilities, critical manufacturing, transportation, and communications critical infrastructure. "RansomHub is a ransomware-as-a-service variant—formerly known as Cyclops and Knight—that has established itself as an efficient and successful service model (recently attracting high-profile affiliates from other prominent variants such as LockBit and ALPHV)," government agencies said . A ransomware-as-a-service (RaaS) platform that's a descendant of Cyclops and Knight, the e-crime operation has attracted high-profile affiliates from other prominent variants such as LockBit

The threat actors behind the BlackByte ransomware group have been observed likely exploiting a recently patched security flaw impacting VMware ESXi hypervisors, while also leveraging various vulnerable drivers to disarm security protections. "The BlackByte ransomware group continues to leverage tactics, techniques, and procedures (TTPs) that have formed the foundation of its tradecraft since its inception, continuously iterating its use of vulnerable drivers to bypass security protections and deploying a self-propagating, wormable ransomware encryptor," Cisco Talos said in a technical report shared with The Hacker News. The exploitation of CVE-2024-37085 , an authentication bypass vulnerability in VMware ESXi that has also been weaponized by other ransomware groups, is a sign that the e-crime group is pivoting from established approaches. BlackByte made its debut in the second half of 2021 and is purported to be one of the autonomous ransomware offshoots to have emerged

Cybersecurity researchers have uncovered a new stealthy piece of Linux malware that leverages an unconventional technique to achieve persistence on infected systems and hide credit card skimmer code. The malware, attributed to a financially motivated threat actor, has been codenamed sedexp by Aon's Stroz Friedberg incident response services team. "This advanced threat, active since 2022, hides in plain sight while providing attackers with reverse shell capabilities and advanced concealment tactics," researchers Zachary Reichert, Daniel Stein, and Joshua Pivirotto said . It's not surprising that malicious actors are constantly improvising and refining their tradecraft, and have turned to novel techniques to evade detection. What makes sedexp noteworthy is its use of udev rules to maintain persistence. Udev, a replacement for the Device File System, offers a mechanism to identify devices based on their properties and configure rules to respond when there is a ch

If you'd like to hear Andy's insights first-hand,  watch Intruder's on-demand webinar . To learn more about reducing your attack surface , reach out to their team today.   Attack surface management vs exposure management Attack surface management (ASM) is the ongoing process of discovering and identifying assets that can be seen by an attacker on the internet, showing where security gaps exist, where they can be used to perform an attack, and where defenses are strong enough to repel an attack. If there's something on the internet that can be exploited by an attacker, it typically falls under the realm of attack surface management. Exposure management takes this a step further to include data assets, user identities, and cloud account configuration. It can be summarized as the set of processes that allow organizations to continually and consistently evaluate

The threat actors behind a recently observed Qilin ransomware attack have stolen credentials stored in Google Chrome browsers on a small set of compromised endpoints. The use of credential harvesting in connection with a ransomware infection marks an unusual twist, and one that could have cascading consequences, cybersecurity firm Sophos said in a Thursday report. The attack, detected in July 2024, involved infiltrating the target network via compromised credentials for a VPN portal that lacked multi-factor authentication (MFA), with the threat actors conducting post-exploitation actions 18 days after initial access took place. "Once the attacker reached the domain controller in question, they edited the default domain policy to introduce a logon-based Group Policy Object (GPO) containing two items," researchers Lee Kirkpatrick, Paul Jacobs, Harshal Gosalia, and Robert Weiland said . The first of them is a PowerShell script named "IPScanner.ps1" that's desi
