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

"Bitdefender analyzed 700,000 high-severity attacks and found that 84% of high-severity attacks now leverage legitimate tools already present inside environments — so-called Living Off the Land (LOTL) techniques. These tactics bypass traditional defenses, operate invisibly, and are increasingly used in targeted intrusions." https://lnkd.in/eaJgZJPs

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

What separates Managed EDR from just “having EDR”? Telemetry alone doesn’t tell the full story.👇 Certutil fires off. A rogue RMM pops up. A sketchy process tree shows up. Looks bad on paper, but without context, you don’t know if it’s a harmless click… or a scam in progress. That’s where Managed EDR earns its keep. Machines catch the signals. Humans connect the dots: - How did they get in? - How far did it spread? - Who else is at risk? Sometimes that means digging through browser history. Sometimes it’s ripping through event logs to find the first bad login. And sometimes it’s wrecking an attacker mid-play before they steal the goods. Our latest blog breaks down how Managed EDR works, what investigations really look like, and why the “managed” part is the difference between chasing alerts and wrecking hackers: https://okt.to/AYI8Fq

AI is great for flagging, but it stops where the script ends. Our team spotted an active compromise—and an automated system would have just sent an alert email and moved on. But our human SOC team didn't stop. They were relentless, calling every available contact until they got a hold of the person being scammed, because they genuinely have your back. That's the Huntress difference. Sometimes, the best tool is the true human connection and the deep commitment people have to keeping each other safe.

“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.

🕵️♂️ MITM Attack: An Overview A Man-in-the-Middle (MITM) attack allows an attacker to secretly intercept and potentially alter communication between two parties. This can lead to stolen credentials, injected malware, or manipulated data. 💡 How It Works: Interception – Using ARP, DNS, or IP spoofing to insert themselves into the communication stream. Manipulation/Decryption – Stripping encryption or injecting malicious content. 🧠 Common Techniques: Packet sniffing Session hijacking SSL stripping DNS/IP spoofing Rogue Wi-Fi access points 📌 Real-World Impact: Equifax’s 2017 breach and ISP-level code injections are examples of MITM’s destructive potential. 🛡️ ARP Spoofing: The Silent MITM Threat 🔍 What is ARP? ARP maps IP addresses to MAC addresses. Devices ask: “Who has this IP?” and receive the MAC address in response. ⚠️ ARP Spoofing Explained Attackers send fake ARP replies to associate their MAC with a legitimate IP (usually the gateway), poisoning the ARP cache and rerouting traffic. 📊 Indicators: Duplicate MAC-to-IP mappings Gratuitous ARP replies Abnormal ARP traffic Gateway redirection patterns ARP probe/reply loops 🧪 Wireshark Filters: arp.opcode == 1 arp.opcode == 2 arp.isgratuitous arp.duplicate-address-detected 🔐 Conclusion: ARP spoofing exploits protocol trust. Early detection is key to preventing interception and manipulation. 🌐 DNS Spoofing: Hijacking the Internet’s Phonebook DNS translates domain names to IP addresses. DNS spoofing corrupts this process, redirecting users to malicious sites. 🔍 How It Works: Victim queries DNS for a domain. Attacker intercepts and sends a fake response pointing to their IP. Victim connects to attacker’s server. Attacker captures credentials. 📊 Indicators: Multiple DNS responses for one query Replies from unexpected IPs Short TTL values Unsolicited responses 🧪 Wireshark Filters: dns[.]flags[.]response == 1 && ip.src != 8[.]8[.]8[.]8 dns[.]qry[.]name == "domain[.]com". 🔐 Conclusion: DNS spoofing often follows ARP poisoning. It redirects victims to attacker-controlled servers. 🔓 SSL Stripping: When HTTPS Becomes HTTP SSL stripping downgrades secure HTTPS connections to HTTP, exposing sensitive data. 💡 How It Works: Victim initiates HTTPS request. Attacker intercepts and connects to real site via HTTPS. Victim is served the site over HTTP. Credentials are sent in plaintext. 📊 Indicators: HTTPS request followed by HTTP traffic Redirects from HTTPS to HTTP TLS handshake anomalies Cleartext credentials in POST requests 🧪 Wireshark Filters: tls || ssl http && ip.src == IP && ip.dst == IP ✅ Confirmed: TLS handshakes with real server DNS spoofing redirected traffic Victim communicated over HTTP Credentials captured in plaintext #CyberSecurity #MITMAttack #ARPspoofing #DNSspoofing #SSLstripping #Wireshark #SOC #Infosec #TryHackMe #DevvartRaj #CyberKillChain #ThreatDetection
