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...

It's worth noting that Trend Micro recently reported that threat actors are actively exploiting proof-of-concept (PoC) exploits for other recently disclosed security ...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...

As security technology and threat awareness among organizations improves so do the adversaries who are adopting and relying on new techniques to maximize speed and impact while evading detection. Ransomware and malware continue to be the method of choice by big game hunting (BGH) cyber criminals, and the increased use of hands-on or "interactive intrusion" techniques is especially alarming. Unlike malware attacks that rely on automated malicious tools and scripts, human-driven intrusions use the creativity and problem-solving abilities of attackers. These individuals can imitate normal user or administrative behaviors, making it challenging to distinguish between legitimate activities and cyber-attacks. The goal of most security practitioners today is to manage risk at scale. Gaining visibility, reducing the noise, and securing the attack surface across the enterprise requires the right people, processes, and security solutions. With the use of penetration testing services , organ...

Russian-speaking users have been targeted as part of a new campaign distributing a commodity trojan called DCRat (aka DarkCrystal RAT) by means of a technique known as HTML smuggling . The development marks the first time the malware has been deployed using this method, a departure from previously observed delivery vectors such as compromised or fake websites, or phishing emails bearing PDF attachments or macro-laced Microsoft Excel documents. "HTML smuggling is primarily a payload delivery mechanism," Netskope researcher Nikhil Hegde said in an analysis published Thursday. "The payload can be embedded within the HTML itself or retrieved from a remote resource." The HTML file, in turn, can be propagated via bogus sites or malspam campaigns. Once the file is launched via the victim's web browser, the concealed payload is decoded and downloaded onto the machine. The attack subsequently banks on some level of social engineering to convince the victim to ope...

Imagine trying to find a needle in a haystack, but the haystack is on fire, and there are a million other needles you also need to find. That's what dealing with security alerts can feel like. SIEM was supposed to make this easier, but somewhere along the way, it became part of the problem. Too many alerts, too much noise, and not enough time to actually stop threats. It's time for a change. It's time to reclaim control. Join Zuri Cortez and Seth Geftic for an insightful webinar as they navigate the complexities of " Solving the SIEM Problem: A Hard Reset on Legacy Solutions ."  They'll share insider knowledge, battle-tested strategies, and a clear path to taming the SIEM beast in this informative session. Here's what we'll cover: SIEM 101: A quick refresher on what SIEM is, why it's important, and the challenges it faces today The Problem with Legacy SIEM: We'll pull back the curtain and reveal why traditional solutions are struggl...

A now-patched security vulnerability in OpenAI's ChatGPT app for macOS could have made it possible for attackers to plant long-term persistent spyware into the artificial intelligence (AI) tool's memory. The technique, dubbed SpAIware , could be abused to facilitate "continuous data exfiltration of any information the user typed or responses received by ChatGPT, including any future chat sessions," security researcher Johann Rehberger said . The issue, at its core, abuses a feature called memory , which OpenAI introduced earlier this February before rolling it out to ChatGPT Free, Plus, Team, and Enterprise users at the start of the month. What it does is essentially allow ChatGPT to remember certain things across chats so that it saves users the effort of repeating the same information over and over again. Users also have the option to instruct the program to forget something. "ChatGPT's memories evolve with your interactions and aren't linked to s...

Phishing attacks are becoming more advanced and harder to detect, but there are still telltale signs that can help you spot them before it's too late. See these key indicators that security experts use to identify phishing links: 1. Check Suspicious URLs  Phishing URLs are often long, confusing, or filled with random characters. Attackers use these to disguise the link's true destination and mislead users.  The first step in protecting yourself is to inspect the URL carefully. Always ensure it begins with "HTTPS," as the "s" indicates a secure connection using an SSL certificate.  However, keep in mind that SSL certificates alone are not enough. Cyber attackers have increasingly used legitimate-looking HTTPS links to distribute malicious content. This is why you should be suspicious of links that are overly complex or look like a jumble of characters.  Tools like ANY.RUN's Safebrowsing allow users to check suspicious links in a secure and isolated environment ...

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....

Cybersecurity researchers have warned of ongoing phishing campaigns that abuse refresh entries in HTTP headers to deliver spoofed email login pages that are designed to harvest users' credentials. "Unlike other phishing webpage distribution behavior through HTML content, these attacks use the response header sent by a server, which occurs before the processing of the HTML content," Palo Alto Networks Unit 42 researchers Yu Zhang, Zeyu You, and Wei Wang said . "Malicious links direct the browser to automatically refresh or reload a web page immediately, without requiring user interaction." Targets of the large-scale activity, observed between May and July 2024, include large corporations in South Korea, as well as government agencies and schools in the U.S. As many as 2,000 malicious URLs have been associated with the campaigns. Over 36% of the attacks have singled out the business-and-economy sector, followed by financial services (12.9%), government (6.9%)...

The proliferation of cybersecurity tools has created an illusion of security. Organizations often believe that by deploying a firewall, antivirus software, intrusion detection systems, identity threat detection and response , and other tools, they are adequately protected. However, this approach not only fails to address the fundamental issue of the attack surface but also introduces dangerous third-party risk to the mix. The world of cybersecurity is in a constant state of flux, with cybercriminals becoming increasingly sophisticated in their tactics. In response, organizations are investing heavily in cybersecurity tools, hoping to build an impenetrable fortress around their digital assets. However, the belief that adding "just one more cybersecurity tool" will magically fix your attack surface and enhance your protection is a dangerous misconception. The limitations of cybersecurity tools Cybersecurity tools, while essential, have inherent limitations. They are designe...
