Cisco Issues Urgent Fix for ASA and FTD Software Vulnerability Under Active Attack

Oct 24, 2024 Vulnerability / Network Security
Cisco on Wednesday said it has released updates to address an actively exploited security flaw in its Adaptive Security Appliance (ASA) that could lead to a denial-of-service (DoS) condition. The vulnerability, tracked as CVE-2024-20481 (CVSS score: 5.8), affects the Remote Access VPN (RAVPN) service of Cisco ASA and Cisco Firepower Threat Defense (FTD) Software. Arising due to resource exhaustion, the security flaw could be exploited by unauthenticated, remote attackers to cause a DoS of the RAVPN service. "An attacker could exploit this vulnerability by sending a large number of VPN authentication requests to an affected device," Cisco said in an advisory. "A successful exploit could allow the attacker to exhaust resources, resulting in a DoS of the RAVPN service on the affected device." Restoration of the RAVPN service may require a reload of the device depending on the impact of the attack, the networking equipment company added. While there are no dire
The Rise of Zero-Day Vulnerabilities: Why Traditional Security Solutions Fall Short

The Rise of Zero-Day Vulnerabilities: Why Traditional Security Solutions Fall Short

Oct 15, 2024 Threat Detection / Machine Learning
In recent years, the number and sophistication of zero-day vulnerabilities have surged, posing a critical threat to organizations of all sizes. A zero-day vulnerability is a security flaw in software that is unknown to the vendor and remains unpatched at the time of discovery. Attackers exploit these flaws before any defensive measures can be implemented, making zero-days a potent weapon for cybercriminals. A recent example is, for instance, CVE-2024-0519 in Google Chrome: this high-severity vulnerability was actively exploited in the wild and involved an out-of-bounds memory access issue in the V8 JavaScript engine. It allowed remote attackers to access sensitive information or trigger a crash by exploiting heap corruption.  Also, the zero-day vulnerability at Rackspace caused massive trouble. This incident was a zero-day remote code execution vulnerability in ScienceLogic's monitoring application that led to the compromise of Rackspace's internal systems. The breach expose

Researchers Uncover Hijack Loader Malware Using Stolen Code-Signing Certificates

Researchers Uncover Hijack Loader Malware Using Stolen Code-Signing Certificates

Oct 15, 2024 Threat Detection / Malware
Cybersecurity researchers have disclosed a new malware campaign that delivers Hijack Loader artifacts that are signed with legitimate code-signing certificates. French cybersecurity company HarfangLab, which detected the activity at the start of the month, said the attack chains aim to deploy an information stealer known as Lumma. Hijack Loader , also known as DOILoader, IDAT Loader, and SHADOWLADDER, first came to light in September 2023. Attack chains involving the malware loader typically involve tricking users into downloading a booby-trapped binary under the guise of pirated software or movies. Recent variations of these campaigns have been found to direct users to fake CAPTCHA pages that urge site visitors to prove they are human by copying and running an encoded PowerShell command that drops the malicious payload in the form of a ZIP archive. HarfangLab said it observed three different versions of the PowerShell script starting mid-September 2024 - A PowerShell script

5 Steps to Boost Detection and Response in a Multi-Layered Cloud

5 Steps to Boost Detection and Response in a Multi-Layered Cloud

Oct 14, 2024 Cloud Security / Vulnerability
The link between detection and response (DR) practices and cloud security has historically been weak. As global organizations increasingly adopt cloud environments, security strategies have largely focused on "shift-left" practices—securing code, ensuring proper cloud posture, and fixing misconfigurations. However, this approach has led to an over-reliance on a multitude of DR tools spanning cloud infrastructure, workloads, and even applications. Despite these advanced tools, organizations often take weeks or even months to identify and resolve incidents.  Add to this the challenges of tool sprawl, soaring cloud security costs, and overwhelming volumes of false positives, and it becomes clear that security teams are stretched thin. Many are forced to make hard decisions about which cloud breaches they can realistically defend against.  By following these five targeted steps, security teams can greatly improve their real-time detection and response capabilities for cloud a

Google Joins Forces with GASA and DNS RF to Tackle Online Scams at Scale

Oct 09, 2024 Cybercrime / Threat Detection
Google on Wednesday announced a new partnership with the Global Anti-Scam Alliance ( GASA ) and DNS Research Federation ( DNS RF ) to combat online scams . The initiative, which has been codenamed the Global Signal Exchange ( GSE ), is designed to create real-time insights into scams, fraud, and other forms of cybercrime pooling together threat signals from different data sources in order to create more visibility into the facilitators of cybercrime. "By joining forces and establishing a centralized platform, GSE aims to improve the exchange of abuse signals, enabling faster identification and disruption of fraudulent activities across various sectors, platforms and services," Google said in a blog post shared with The Hacker News. "The goal is to create a user-friendly, efficient solution that operates at an internet-scale, and is accessible to qualifying organizations, with GASA and the DNS Research Federation managing access."

New Perfctl Malware Targets Linux Servers for Cryptocurrency Mining and Proxyjacking

New Perfctl Malware Targets Linux Servers for Cryptocurrency Mining and Proxyjacking

Oct 03, 2024 Linux / Malware
Misconfigured and vulnerable Linux servers are the target of an ongoing campaign that delivers a stealthy malware dubbed perfctl with the primary aim of running a cryptocurrency miner and proxyjacking software. "Perfctl is particularly elusive and persistent, employing several sophisticated techniques," Aqua security researchers Assaf Morag and Idan Revivo said in a report shared with The Hacker News. "When a new user logs into the server, it immediately stops all 'noisy' activities, lying dormant until the server is idle again. After execution, it deletes its binary and continues to run quietly in the background as a service." It's worth noting that some aspects of the campaign were disclosed last month by Cado Security, which detailed an activity cluster that targets internet-exposed Selenium Grid instances with both cryptocurrency mining and proxyjacking software. Specifically, the fileless perfctl malware has been found to exploit a security
5 Must-Have Tools for Effective Dynamic Malware Analysis

5 Must-Have Tools for Effective Dynamic Malware Analysis

Oct 02, 2024 Malware Analysis / Threat Detection
Dynamic malware analysis is a key part of any threat investigation. It involves executing a sample of a malicious program in the isolated environment of a malware sandbox to monitor its behavior and gather actionable indicators. Effective analysis must be fast, in-depth, and precise. These five tools will help you achieve it with ease. 1. Interactivity Having the ability to interact with the malware and the system in real-time is a great advantage when it comes to dynamic analysis. This way, you can not only observe its execution but also see how it responds to your inputs and triggers specific behaviors.  Plus, it saves time by allowing you to download samples hosted on file-sharing websites or open those packed inside an archive, which is a common way to deliver payloads to victims. The initial phishing email containing the malicious pdf and password for the archive Check out this sandbox session in the ANY.RUN sandbox that shows how interactivity is used for analyzing the en

How to Plan and Prepare for Penetration Testing

How to Plan and Prepare for Penetration Testing

Sep 27, 2024 Penetration Testing / Threat Detection
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.
