Virtualization and networking infrastructure have been targeted by a threat actor codenamed Fire Ant as part of a prolonged cyber espionage campaign. The activity, observed this year, is primarily designed Now to infiltrate organizations' VMware ESXi and vCenter environments as well as network appliances, Sygnia said in a new report published today. "The threat actor leveraged combinations of sophisticated and stealthy techniques creating multilayered attack kill chains to facilitate access to restricted and segmented network assets within presumed to be isolated environments," the cybersecurity company said . "The attacker demonstrated a high degree of persistence and operational maneuverability, operating through eradication efforts, adapting in real time to eradication and containment actions to maintain access to the compromise infrastructure." Fire Ant is assessed to share tooling and targeting overlaps with prior campaigns orchestrated by UNC3886 , a...

Security Operations Center (SOC) teams are facing a fundamentally new challenge — traditional cybersecurity tools are failing to detect advanced adversaries who have become experts at evading endpoint-based defenses and signature-based detection systems. The reality of these "invisible intruders" is driving a significant need for a multi-layered approach to detecting threats, including Network Detection and Response (NDR) solutions.  The invisible intruder problem Imagine your network has been compromised — not today or yesterday, but months ago. Despite your significant investments in security tools running 24/7, an advanced adversary has been quietly moving through your systems, carefully avoiding detection. They've stolen credentials, established backdoors, and exfiltrated sensitive data, all while your dashboards showed nothing but green. This scenario is not hypothetical. The average dwell time for attackers — the period between initial compro...

An often overlooked feature of log management software is the ability to conduct forensic analysis of historical events. If your network goes down, your network monitoring tool can tell you what happened, but knowing why it happened is even more valuable. SolarWinds Log & Event Manager has cutting-edge IT search for fast and easy forensic analysis. Here are six ways that the forensic analysis feature of Log & Event Manager can help you piece together what really happened. You can download a free, fully functional 30-day trial of Log & Event Manager from here. 1) ID file changes When collecting logs, you're going to see millions of file changes. How do you know which ones to isolate? It's best to isolate file changes against critical files (protected docs, financial information, personal documents, HR records, etc.). Look at file changes from a forensic approach to determine if suspicious activity has occurred. Often times, a virus will affect file attrib...

The evolution of cyber threats has forced organizations across all industries to rethink their security strategies. As attackers become more sophisticated — leveraging encryption, living-off-the-land techniques, and lateral movement to evade traditional defenses — security teams are finding more threats wreaking havoc before they can be detected. Even after an attack has been identified, it can be hard for security teams to prove to auditors that they have fully mitigated the issues that allowed the attackers in. Security teams worldwide have prioritized endpoint detection and response (EDR), which has become so effective that threat actors have changed their tactics to avoid attack vectors protected by host-based defenses. These advanced threats are particularly vexing for critical infrastructure providers in financial services , energy and utilities , transportation , and government agencies that may have proprietary systems that cannot be protected by traditional endpoint securi...

NetworkMiner 1.1 -  Network Forensic Analysis Tool (NFAT) Released  NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows. NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files.NetworkMiner collects data (such as forensic evidence) about hosts on the network rather than to collect data regarding the traffic on the network. The main user interface view is host centric (information grouped per host) rather than packet centric (information showed as a list of packets/frames). Consider a scenario where you're analyzing a suspicious website, wishing to understand the way that it might try attacking its visitors. One way to approach this challenge is to browse the website using a Windows ...

Let's be honest, a network attack of any scale is inevitable in today's IT world. Do you have the ability to quickly identify the details of the attack? If your network goes down, your network monitoring tool can tell you what happened, but knowing details about who was vulnerable or why the attack happened is even more valuable. An often overlooked feature of log management software is the ability to conduct forensic analysis of events. Instead of searching for a needle in a haystack, forensic analysis tools can make drilling down to identify details a quick and easy task. SolarWinds Log & Event Manager has cutting-edge IT search for fast and easy forensic analysis. Here are six ways that the forensic analysis feature of Log & Event Manager can help you piece together what really happened. 1) Incident response Say goodbye to complex queries. Conducting forensic analysis, in general, is a quicker and simpler way to do incident response. The faster you...

In the past, the autonomous breach protection company Cynet announced that it is making Cynet 360 threat detection and response platform available at no charge for IR (incident response) service providers and consultants. Today Cynet takes another step and announces a $500 grant for Incident Responders for each IR engagement in which Cynet 360 was used, with an additional $1,000 grant if the customer if the customer purchases an annual Cynet 360 subscription after the IR process is concluded. Learn about this new offering here . Incident response investigations come in a thousand different variations, but most can be broken down into two main parts. The first is discovering the few suspicious machines, user accounts, and network connections out of the mass activities within the attacked environment. The second part follows these discoveries and involves a surgical-like collection and analysis of forensic artifacts to refute or validate the suspicion and if validated to disclo...

Book Review : Defense against the Black Arts How Hackers Do What They Do and How to Protect against It Ben Rothke  write a review of a   new book on hacking " Defense against the Black Arts: How Hackers Do What They Do and How to Protect against It ". Authors are Jesse Varsalone, Matthew Mcfadden, Michael Schearer and Sean Morrissey. " If there ever was a book that should not be judged by its title, Defense against the Black Arts: How Hackers Do What They Do and How to Protect against It, is that book. Even if one uses the definition in The New Hackers Dictionary of 'a collection of arcane, unpublished, and (by implication) mostly ad-hoc techniques developed for a particular application or systems area', that really does not describe this book. The truth is that hacking is none of the above. If anything, it is a process that is far from mysterious, but rather aether to describe. With that, the book does a good job of providing the reader with the information ne...

Many enterprises rely on more than one security tool to protect their technology assets, devices, and networks. This is particularly true for organizations that use hybrid systems or a combination of cloud and local applications. Likewise, companies whose networks include a multitude of smartphones and IoT devices are likely to deploy multiple security solutions suitable for different scenarios. Employing several security solutions tends to be inevitable for many, especially those that have outgrown their previous network setups. Companies that expand to new branches and even overseas operations have to make use of additional security measures and tools. This use of multiple tools or software often leads to critical issues, though. The management of the many cybersecurity solutions can become too complicated and difficult to handle, especially for organizations with little experience in addressing cyber threats, let alone actual attacks. This can result in confusion and the inabilit...

After disclosing CIA's strategies to hijack and manipulate webcams and microphones to corrupt or delete recordings, WikiLeaks has now published another Vault 7 leak , revealing CIA's ability to spy on video streams remotely in real-time. Dubbed ' CouchPotato ,' document leaked from the CIA details how the CIA agents use a remote tool to stealthy collect RTSP/H.264 video streams. Real Time Streaming Protocol, or RTSP, is a network control protocol designed for use in entertainment and communication systems for controlling streaming media servers. CouchPotato gives CIA hackers ability to "collect either the stream as a video file (AVI) or capture still images (JPG) of frames from the stream that are of significant change from a previously captured frame," a leaked CIA manual reads. The tool utilises FFmpeg for video and image encoding and decoding and Real Time Streaming Protocol connectivity. The CouchPotato tool works stealthily without leaving...
