You patch your perimeter. You harden your VPN. You deploy a next-generation firewall. And then, three weeks later, a threat actor who slipped in through a phishing email has quietly moved through fourteen servers, elevated their privileges to domain admin, and is exfiltrating data from your ERP system—all while staying well below your alerting thresholds.
This is lateral movement, and it is the defining technique that separates a nuisance intrusion from a catastrophic breach. For Indian enterprises navigating an increasingly hostile threat landscape—ransomware gangs, state-linked actors, and opportunistic cybercriminals—understanding and stopping lateral movement is one of the most consequential security investments you can make in 2025.
Once an attacker gains an initial foothold—typically through phishing, a compromised credential, or an unpatched public-facing service—their next objective is not immediate data theft. Instead, they explore and expand. Lateral movement is the collection of techniques attackers use to navigate from an initial entry point across a network to reach their true target: the finance server, the Active Directory domain controller, the backup infrastructure, the regulated data store.
According to threat intelligence aggregated across MSSP operations, the median dwell time—the period between initial compromise and detection—remains alarmingly high for organisations without mature SOC coverage. During that window, attackers are rarely sitting still. They are harvesting credentials, escalating privileges, establishing persistence, and moving sideways.
For Indian enterprises specifically, the stakes are sharpening. The Digital Personal Data Protection (DPDP) Act, 2023, imposes obligations on Data Fiduciaries to maintain security safeguards commensurate with the sensitivity of data processed. A breach facilitated by undetected lateral movement—where an attacker had domain-level access for weeks—would be very difficult to defend in a regulatory inquiry. CERT-In’s 6-hour incident reporting mandate makes this even more acute: if you cannot detect lateral movement quickly, you cannot report within the required window.
Modern threat actors draw from a well-documented toolkit. Understanding these techniques is the first step toward building effective detection and response capability.
Rather than cracking a password, an attacker steals the hash of a credential from memory (typically using tools like Mimikatz on a compromised Windows host) and reuses it to authenticate to other systems. Pass-the-Ticket extends this to Kerberos tickets in Active Directory environments, allowing attackers to impersonate privileged accounts without knowing the plaintext password. Both techniques are devastatingly effective against organisations that have not implemented credential isolation, local admin account hygiene, or Protected Users security groups in Active Directory.
Any authenticated domain user can request Kerberos service tickets for accounts with Service Principal Names (SPNs) registered. Attackers request these tickets and then attempt offline brute-force against them. If a service account has a weak password and high privileges—a common configuration in legacy enterprise environments—Kerberoasting can yield domain admin access within hours. Indian enterprises with large, aging Active Directory deployments are particularly exposed.
Once inside the network, attackers frequently exploit internal services that were never designed to face a hostile actor: SMB shares, WMI, RDP, PsExec, DCOM, and Windows Remote Management. These are legitimate management protocols, which is precisely what makes them difficult to block outright and easy to abuse for lateral movement. A well-segmented network with internal firewalling significantly constrains which hosts can reach which services.
Sophisticated attackers increasingly avoid deploying custom malware at all, instead using native tools—PowerShell, WMI, certutil, mshta, regsvr32—to blend their activity into the background of normal IT operations. This makes signature-based detection largely ineffective. Detecting LotL requires behavioural analysis: identifying unusual process parentage, abnormal scripting activity, or out-of-hours admin tool usage.
Techniques like DCSync (simulating domain controller replication to extract password hashes), Golden Ticket attacks (forging Kerberos tickets using a compromised KRBTGT hash), and AdminSDHolder abuse allow attackers who reach a domain controller or privileged AD position to achieve persistence that survives password resets and even domain rebuilds. Protecting Active Directory is not optional—it is the single most important control for stopping lateral movement in its tracks.
The architectural assumption of traditional security—that threats come from outside and can be blocked at the edge—does not hold against lateral movement. Once an attacker is inside, they move between endpoints and servers over protocols the firewall allows. East-west traffic (server to server, workstation to server) has historically received far less scrutiny than north-south traffic (internet to internal), and attackers know this.
A flat network—one where every workstation can reach every server, every server can reach every other server, and administrative protocols are wide open—is the attacker’s playground. Lateral movement in a flat network is constrained only by the attacker’s knowledge and patience, not by any technical control.
PJ Networks deploys FortiGate Next-Generation Firewalls not just at the perimeter but as Internal Segmentation Firewalls (ISFW) within enterprise networks. This is a fundamental architectural shift: instead of assuming trust between internal systems, every zone boundary is enforced.
In a properly segmented FortiGate deployment, the following controls actively constrain lateral movement:
Segmentation does not stop a determined attacker permanently—but it forces them to make noise. Every attempted hop across a segment boundary that violates policy generates a log event. In aggregate, these events tell the story of lateral movement before the attacker reaches their target.
Segmentation generates telemetry; a Security Operations Centre makes that telemetry actionable. PJ Networks operates a 24/7 SOC staffed by analysts who focus specifically on adversarial behaviour patterns—not just signature hits or threshold alerts.
Lateral movement typically unfolds over hours or days. An alert at 11:47 PM on a Tuesday that a service account authenticated to a new host from an unusual IP is individually low-severity. In the context of four similar events over the previous 72 hours, each crossing a different network segment, it is a high-confidence indicator of an active intrusion. This kind of pattern recognition—correlating across time, across hosts, across log sources—requires both the right tooling and experienced human analysts who understand attacker tradecraft.
The SOC also plays a critical role in meeting CERT-In’s 6-hour reporting window. When lateral movement is detected, the clock starts. An effective SOC does not just detect; it immediately initiates triage, scoping, and evidence preservation in parallel with drafting the initial notification to CERT-In. Without this operational readiness, the 6-hour window is nearly impossible to meet for complex incidents.
Detecting lateral movement demands visibility across every layer of the enterprise: network traffic, endpoint logs, identity and authentication events, application logs, and physical access systems. Fragmented tooling—a SIEM here, a network monitor there, a separate ticketing system—creates the gaps attackers exploit.
PrahiX Ora is a unified SecOps platform built by PrahiX Tech Pvt Ltd. PJ Networks is its primary field deployment and operations partner, and we deploy and operate it for clients across manufacturing, BFSI, healthcare, and logistics. Its four integrated pillars directly address the visibility requirements for detecting and responding to lateral movement:
Ora’s SIEM ingests logs from firewalls, endpoints, identity providers, cloud platforms, and applications into a single correlation engine. Detection rules are mapped to the MITRE ATT&CK framework, so lateral movement techniques like Pass-the-Hash (T1550.002), Remote Services (T1021), and Kerberoasting (T1558.003) surface as named, actionable alerts rather than raw log noise. Graph-based attack storyline reconstruction connects individual events into a coherent narrative—an analyst can see the full chain from initial phishing email to the fourth lateral hop in a single view. Tiered retention (hot/cold/archive) supports CERT-In’s direction on 180-day in-country log retention, ensuring forensic evidence is available if an incident is investigated weeks after containment.
Ora’s Network Management System provides unified observability across firewalls, switches, access points, and WAN/SD-WAN links. LLDP/CDP topology discovery builds an accurate, always-current map of the network—essential for understanding whether an observed connection between two hosts represents normal traffic or an unexpected lateral path. Network path tracing and ML-based anomaly detection flag connections that deviate from the learned baseline. For Indian enterprises running complex multi-vendor estates where NOC visibility has historically been fragmented across separate tools, this single-pane view is transformative.
Lateral movement investigations sometimes surface a critical question: was that admin credential used by a legitimate person at the keyboard, or was it a remote attacker? Ora’s video surveillance (VMS) module manages ONVIF, Hikvision, and Dahua cameras with video analytics, bringing physical and network security under one operational view. For manufacturing, retail, and multi-site estates, correlating a suspicious authentication event with physical access logs and camera footage can be the difference between closing an investigation confidently and leaving a question mark in the incident report.
Speed is everything in lateral movement response. Ora’s SOAR module executes pre-built response playbooks automatically when high-confidence lateral movement indicators fire: isolating a compromised host, pushing attacker IP addresses to FortiGate blocklists, revoking active sessions for a compromised account, and triggering notification workflows. For the CERT-In 6-hour reporting window, automation is not a convenience—it is what makes the timeline operationally realistic. Human analysts cannot manually execute every response action across a complex enterprise environment within six hours; orchestration handles the mechanical steps so analysts can focus on scoping and decision-making.
If your organisation is managing lateral movement risk with fragmented tools and manual processes, the gap between your detection capability and what a motivated attacker needs is wider than you think. We would be glad to walk you through how Ora is deployed in environments similar to yours.
If your organisation has not yet addressed lateral movement as a distinct threat category, here is a prioritised starting point:
Lateral movement is not a sophisticated, nation-state-only threat. It is the standard operating procedure of ransomware groups, data extortion actors, and financially motivated criminals targeting Indian enterprises every day. What makes it dangerous is not technical complexity—most techniques are well-documented—but the window of undetected access that a flat network and limited visibility provide.
Shrinking that window requires three things working together: network architecture that forces adversaries to make noise as they move, continuous monitoring that recognises that noise as adversarial activity, and automated response that closes the gap between detection and containment before irreversible damage occurs.
PJ Networks provides all three through FortiGate internal segmentation, 24/7 NOC/SOC operations, and deployment of the PrahiX Ora platform. Whether you are at the beginning of your security maturity journey or hardening an already robust programme, we are available to assess your lateral movement exposure and recommend targeted improvements.
