🚨 On-Demand Session: A Battle Against Three Persistent Threat Actors 🚨 Check out the latest on-demand session presented by Amnon Kushnir, Oren Biderman and Ori Porag. The story began when a client contacted us for help with what appeared to be a standard #incidentresponse. But soon, we realized this was no ordinary case—it was a roller coaster ride into the depths of an advanced #cyberattack. Sygnia's investigation revealed not one, but 𝘁𝗵𝗿𝗲𝗲 highly sophisticated #Chinanexus threat actors, all within one environment! Tune in to learn more insights into how we navigated this complex situation, learned valuable lessons, and ultimately defeated these advanced threat actors: https://lnkd.in/dUpMSYcv #CyberSecurity #ThreatIntelligence #IncidentResponse #CloudSecurity

The infamous #SolarWinds #breach – a sophisticated #supplychain #attack that infiltrated the company's software and impacted numerous government agencies and Fortune 500 companies – forced everyone to consider this question and their far-reaching third-party dependencies. Yet more than three years later, identifying a breach still takes an average of 204 days. It’s not for a lack of threat data. In fact, most under-resourced security teams are drowning in alerts. With time on their side, #adversaries continue to evolve, adopting stealthier methods to evade detection such as: ▶️Dynamic-link library (DLL) side-loading. ▶️Web shell attacks. ▶️Fileless malware attacks. ▶️Open-source software abuse. Many organizations are turning to #MDR services which provides 24/7/365 protection based on complete visibility across IT and OT environments to keep organizations continuously secure.

🔲 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐭𝐡𝐞 𝐑𝐞𝐦𝐞𝐝𝐢𝐚𝐭𝐢𝐨𝐧 𝐃𝐨𝐦𝐢𝐧𝐨 𝐄𝐟𝐟𝐞𝐜𝐭? 🔲 ➡️ When we implement a large-scale, comprehensive #remediation effort, we're adjusting configurations within the #IT environment. We're reshaping the entire network landscape. ➡️ These changes have a ripple effect that reaches far beyond the IT department—they also impact #threatactors who rely on stability and predictability to sustain prolonged operations.   ➡️ Threat actors constantly adapt to network changes. Whether it’s segmentation of #subnets, deployment of new tools, or other major shifts, they’re accustomed to adjusting to continue their campaigns. ➡️ Interestingly, while they may not understand the exact purpose behind our actions, they know they need to adapt swiftly.   ➡️ This adaptation period creates what we call a golden timeframe. Right after implementing our remediation and monitoring measures, we have a unique window to identify #anomalies - be it rogue internal activity or an active threat campaign. During this critical phase, both legitimate and malicious activities stand out, offering us a chance to #detect behavior that doesn't align with our updated security measures.   ➡️ Ultimately, every change presents opportunities on both sides. For the threat actor an incomplete or incorrect remediation plan might create new #attack #vectors. For the #defenders, if a remediation plan is robust, at this moment the defender has the upper hand.   Learn more about this in our latest webinar featuring Amnon Kushnir and Oren Biderman: https://lnkd.in/dUpMSYcv

The deployment of #intrusive #securitytools such as Endpoint Detection and Response (#EDR) systems, Network Firewalls, Network Access Control (#NAC) solutions, Intrusion Prevention Systems (#IPS), Web Application Firewalls (#WAFs), and Security Orchestration, Automation and Response (#SOAR) platforms, plays a pivotal role in maintaining business continuity and safeguarding IT systems. ➡️ These solutions often go beyond basic and static prevention, offering advanced analytics and automation capabilities to detect attacks based on behavioral anomalies on top of known #threat signatures. ➡️ In dynamic and high-stakes environments, where threat patterns are constantly shifting, these capabilities are critical for identifying previously unknown threats. ➡️ However, they can also be #intrusive, as they require deep #integration with IT systems and the authority to intervene in real-time.

Sygnia’s top #incidentresponse team recently took the stage at the prestigious #SANS Forensics Summit, presenting “How Persistent is an APT? Battling Three Threat Actors in a Single Environment.” Their key takeaway: ▶️ To prevail, #defenders must be even more persistent and resourceful than the #APTs they face. Adam Finkelstein Ori Porag Christopher Crummey What does that entail for security teams? Tune in to learn more: https://lnkd.in/dzexfriB

Industrial and #critical #infrastructures continue to undergo #digitaltransformation to achieve greater efficiency, increase agility, and improve sustainability. Today, the leading critical infrastructure #cybersecurity challenge is what Sygnia calls “industrial grade ransomware” attacks on the #IT layers of industrial and critical infrastructures that put the target organization’s operational technologies at risk. ⏺️ 𝟰𝟬% 𝗼𝗳 𝗥𝗮𝗻𝘀𝗼𝗺𝘄𝗮𝗿𝗲 𝗔𝘁𝘁𝗮𝗰𝗸𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗨𝗦 𝗧𝗮𝗿𝗴𝗲𝘁𝗲𝗱 𝗖𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 ⏺️ 𝟮𝟮% 𝗼𝗳 𝗥𝗮𝗻𝘀𝗼𝗺𝘄𝗮𝗿𝗲 𝗔𝘁𝘁𝗮𝗰𝗸𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗘𝗨 𝗧𝗮𝗿𝗴𝗲𝘁𝗲𝗱 𝗠𝗮𝗻𝘂𝗳𝗮𝗰𝘁𝘂𝗿𝗶𝗻𝗴 Critical infrastructure cybersecurity threats include #supplychain #attacks, #espionage, and destructive attacks intended to disrupt operations and cause maximum damage.

There are four ways to test your organization’s ability to respond to a cyber incident: ⏺️ 𝐄𝐱𝐞𝐜𝐮𝐭𝐢𝐯𝐞 𝐭𝐚𝐛𝐥𝐞𝐭𝐨𝐩 𝐞𝐱𝐞𝐫𝐜𝐢𝐬𝐞𝐬 - Prepare business executives and security leaders by evaluating whether all relevant stakeholders know their roles and responsibilities, communications plans, and the battle rhythm of #incidentresponse. ⏺️ 𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 #𝐭𝐚𝐛𝐥𝐞𝐭𝐨𝐩 𝐞𝐱𝐞𝐫𝐜𝐢𝐬𝐞𝐬 - Prepare security leaders by evaluating whether they understand who is authorized to make technical decisions and whether technical teams understand the escalation process from #alerts to events to correlated incident to #cybercrisis. They also evaluate the handoff between technical and executive teams. ⏺️ 𝐑𝐞𝐝 𝐓𝐞𝐚𝐦𝐢𝐧𝐠 - Test your security team’s ability to detect and respond to a simulated objective-oriented attack using the tactics, techniques, and procedures (#TTPs) of real-world #adversaries. Targets could include accessing the CEO’s email, accessing sensitive data, or accessing critical systems. ⏺️ 𝐏𝐮𝐫𝐩𝐥𝐞 𝐓𝐞𝐚𝐦𝐢𝐧𝐠 - Provide security teams with the opportunity to practice responding to targeted attacks while simultaneously learning how to improve processes and strengthen detection capability.

Amnon Kushnir was a guest speaker on Dave Bittner's prominent podcast N2K | CyberWire. Amnon discussed how how early 2024, Sygnia observed the ‘#VelvetAnt’ threat group exploiting a zero-day #vulnerability (CVE-2024-20399) to infiltrate #CiscoSwitch appliances and operate undetected within enterprise networks. This attack enables threat actors to escape Cisco’s command interface and install malware directly on the device’s #OS, bypassing standard security tools. The incident underscores the risks posed by third-party appliances and the importance of enhanced monitoring and threat detection to counter advanced persistent #threats.
