Understanding MITM Attacks: ARP Spoofing, DNS Spoofing, SSL Stripping

I just completed Man-in-the-Middle Detection room on TryHackMe. Learn what MITM attack is, and how to identify the footprints of this attack in the network traffic. This was a deep dive into one of the most fascinating and deceptive attack vectors — Man-in-the-Middle (MITM) attacks. These attacks occur when a malicious actor secretly intercepts or alters communication between two parties, making it seem like everything is normal.  🔍 How MITM Attacks Work:   Attackers position themselves between a sender and receiver, intercepting data packets or injecting malicious responses. Common entry points include unsecured Wi-Fi networks, ARP spoofing, or compromised routers.  ⚔️ Types of Network-Based MITM Attacks:   - ARP Spoofing: Manipulating ARP tables to redirect traffic through the attacker.   - DNS Spoofing: Faking DNS responses to lead users to malicious sites.   - HTTPS Spoofing / SSL Stripping: Downgrading secure HTTPS connections to HTTP for easy interception.   - Wi-Fi Eavesdropping: Exploiting open wireless networks to monitor user data.  🛡️ Mitigation Techniques:   - Enforce HTTPS and implement HSTS to secure web traffic.   - Use VPNs and secure network configurations to encrypt communications.   - Implement ARP inspection and DHCP snooping in enterprise networks.   - Educate users to avoid connecting to unsecured Wi-Fi and verify digital certificates.  Completing this room helped me understand not just how these attacks unfold but also how proactive monitoring and strong security controls can prevent real-world breaches.  💡 For security professionals, practicing detection and response in such simulated environments is invaluable — it bridges the gap between theory and hands-on defense. #NetworkSecurity #CyberSecurity #InformationSecurity #BlueTeam #RedTeam #ThreatHunting #IncidentResponse #SOC #SIEM #SOAR #ZeroTrust #NDR #XDR #MITREATTACK #OWASP #TLS #PKI #Zigbee #IoTSecurity #WiFiSecurity #SOC2 #ISO27001 #NIST #RiskManagement #GRC #VulnerabilityManagement #PenTesting #BugBounty #ThreatIntelligence #Phishing #Ransomware #DNSSecurity #EmailSecurity #EndpointSecurity #IdentitySecurity #IAM #PAM #MFA #ZeroDay #DLP #MalwareAnalysis #Forensics #PurpleTeam #SecurityAwareness #SecurityArchitecture #NetworkEngineering #BGP #SDWAN #SASE #ZTA #Firewall #IDS #IPS #TLSInspection #PKIManagement #CertificateManagement

Thrilled to get my self immersed in Wireshark , by doing so you learn to follow a certain workflow template . The goal always is to determine what is happening with the host in question 1-what is the issue? a brief summary of the issue. 2-define our scope and the goal (what are we looking for? which time period?) --Scope: what are we looking for, where? --when the issue started: --supporting info: Files, data sources, anything helpful. 3-define our target(s) (net / host(s) / protocol) --Target hosts: Network or address of hosts. 4-capture network traffic / read from previously captured PCAP. --Perform actions as needed to analyze the traffic for signs of intrusion. 5-identification of required network traffic components (filtering) --once we have our traffic, filter out any traffic not necessary for this investigation to include; any traffic that matches our common baseline, and keep anything relevant to the scope of the investigation. 6-An understanding of captured network traffic --Once we have filtered out the noise, it's time to dig for our targets. Start broad and close the circle around our scope. 7-note taking / mind mapping of the found results. --Annotating everything we do, see, or find throughout the investigation is crucial. Ensure you are taking ample notes, including: ---Timeframes we captured traffic during. ---Suspicious hosts/ports within the network. ---Conversations containing anything suspicious. ( to include timestamps, and packet numbers, files, etc.) 8-summary of the analysis (what did we find?) --Finally, summarize what has been found, explaining the relevant details so that superiors can decide to quarantine the affected hosts or perform a more critical incident response mission. --Our analysis will affect decisions made, so it is essential to be as clear and concise as possible.

For 2.5 months, one IP was relentlessly probing our defenses. It finally stopped. The initial feeling is relief, but the deeper truth is: We paid an invisible price just to survive. A brute force attack that "fails" isn't free. It costs you: Infrastructure: Wasted compute, bandwidth, and log storage. Engineering Time: Manual monitoring, firewall updates, and security team attention. Psychological Burden: The constant, draining fear that this attempt might be the one that gets through. Relying on rate limiting and password complexity is a passive, exhausting defense. Our Chapter: We're on a mission to make brute force attacks not just "fail," but pointless. By using our Autonomous Key Rotation, the static key an attacker is trying to guess is no longer the key. It was changed 10 minutes ago, 5 minutes ago, or even 1 minute ago. We're building the future where attackers don't just give up; they realize the entire premise of the attack is architecturally obsolete.

The Proofpoint Threat Research Team described the threat activity cluster as sophisticated, leveraging web injections and filtering checks as part of its attack chains. https://lnkd.in/gY5Kjzfz

Dr. Carmenatty pulls back the curtain on the single most significant, yet least understood, threat to global data security: the dawn of the Cryptographically Relevant Quantum Computer (CRQC). This is not a theoretical problem; it is a ticking time bomb demanding immediate, decisive action. We expose the dangerous myth of "Quantum Incident Response" and reveal why traditional security centers will offer zero protection against the silent, undetectable "store-now-decrypt-later" attack. You will receive a four-step, actionable blueprint, the Quantum Readiness Plan, to protect your most valuable, long-lived data before the silent detonation occurs. Stop responding to the past. Start preparing for the future. https://lnkd.in/eqUkrbiZ

Companies need to do more to mitigate the potential effects of cyber-attacks, the head of GCHQ has said, including making physical, paper copies of crisis plans to use if an attack brings down entire computer systems.

Spoiler Alert: visibility and proactive threat intelligence matter! CVE-2025-2611 is being actively exploited as attackers leverage unauthenticated command injection in ICTBroadcast to gain remote code execution. In the latest VulnCheck updates post, we unpack how this attack works, what the indicators are, and how organizations can detect and mitigate exposure.

In this video, team up with legendary hacker OTW to uncover how professionals actually use Wireshark the most powerful network analysis tool in cybersecurity. Together, we explore how hackers capture traffic, read encrypted packets, and trace real data moving through Wi-Fi and Ethernet connections. But this isn’t just about hacking — it’s about defense. You’ll learn how to recognize suspicious patterns, secure your own network, and understand how packet sniffing really works at a deep technical level. Whether you’re a cybersecurity student, ethical hacker, or just fascinated by how the internet really works, this episode will change the way you see digital communication forever.

I forgot to hit post on this from the past Sunday. This week on Hack The Box CPTS I look at pivoting, tunneling, and port forwarding. Using proxychains via SSH forwarding/SOCKS proxy and all the commands you can run through that tool, how you can use proxychains with meterpreter, and using socat redirection with reverse/bind shells. I’m about 40% done with this new module and it’s been very interesting to learn how easily firewall and network segmentation can be avoided using these methods. Until next week!

“Vibe-coded” attacks blur attribution by allowing copycats to mimic legitimate threat actors. Simple IoC or TTP matching is no longer enough. Structured models like the Diamond Model of Intrusion Analysis provide the context needed to understand intent and infrastructure.
