Cyber investigation is the discipline of tracing digital crime to its source — identifying threat actors, mapping their infrastructure, documenting their methods, and building the evidentiary record that enables action. Karen IT's investigation team has operated in real-world cases alongside law enforcement agencies, national CERTs, domain registrars, and international cybercrime units.
These three capabilities are often conflated. They are not the same thing, and confusing them leads to investigations that are either too slow, too narrow, or inadmissible.
Incident ResponseFocused on stopping the bleeding. When something is actively wrong — a network is compromised, ransomware is spreading, a service is down — Incident Response is the immediate, operational reaction. The goal is containment and recovery. Time is the primary variable. → [Learn about our Incident Response] | Digital ForensicsFocused on what happened and proving it. Forensics is the disciplined collection and analysis of digital evidence — disk images, memory captures, network logs. The goal is a documented, legally defensible record of events. Accuracy and integrity are the primary variables. → [Learn about our Digital Forensics] | Cyber InvestigationFocused on who did it and how. Investigation goes beyond evidence on a single system. It connects dots across infrastructure, registrar records, and threat intelligence to identify threat actors, map operations, and build a picture that supports attribution. Intelligence is the primary variable. |
All three disciplines work in parallel during major incidents. Investigation without Forensics produces attribution without proof. Forensics without Investigation produces evidence without context. Karen IT provides all three — and coordinates them as a unified process when the scope of a case demands it.
Cyber investigations vary widely in scope and starting point. Some begin with a single malicious URL. Others begin after a breach has already occurred. Some are initiated proactively by organizations that suspect they are being targeted. What they share is the need for systematic, intelligence-driven analysis that goes beyond what automated tools can produce.
Threat Actor AttributionIdentifying who is responsible for a cyber attack, fraud campaign, or malicious infrastructure operation. This involves analyzing technical indicators — IP addresses, domains, SSL certificates — against intelligence databases to build a profile. | Infrastructure MappingThreat actors rarely operate from a single domain. They build infrastructure designed to be resilient and difficult to trace. Using our CTI platform, passive DNS data, and WHOIS correlation, we trace outward from known indicators to uncover the broader network. | Phishing CampaignWe go beyond URL blacklisting. We analyze the full campaign: the kit used, its hosting infrastructure, related domains, and the actor's patterns. Our KitWatch repository allows us to identify kit reuse across campaigns run by the same actor. |
Business Email CompromiseBEC attacks are among the most financially damaging forms of cybercrime. Our investigation covers the full attack chain: the compromised account, the infrastructure used, the financial trail, and attribution indicators. We structure findings to meet evidentiary standards. | Domain & Brand AbuseWhen your brand is impersonated, investigation is needed before takedown. We investigate how many domains are involved, registration details, shared infrastructure, and campaign coordination. This builds evidence for legal proceedings. | Malware InfrastructureCommand-and-control servers and drop zones represent infrastructure that can be mapped and disrupted. We work from malware samples and network indicators to reconstruct the full operational infrastructure of a campaign to support defensive action. |
Every investigation begins with a defined scope and objective. We do not conduct open-ended fishing exercises. Each engagement has a clear question — or set of questions — that we are working to answer.
| 01 | Scoping & Objective SettingBefore any analysis begins, we establish what you are trying to determine and what you will do with the findings. Are you building a law enforcement referral? Supporting a civil legal claim? The end use shapes the methodology and documentation standard. |
| 02 | Indicator Collection & SeedingWe begin with what is known: a domain, an IP address, an email header, a malware sample. These seeds are systematically expanded using our CTI platform, threat intelligence feeds, and OSINT — always with a documented chain of reasoning. |
| 03 | Infrastructure & Actor AnalysisAs the indicator set grows, patterns emerge: infrastructure clusters, registration timing, shared hosting. We analyze these patterns to build a picture of the actor's operational methodology. This phase substantially expands the scope of what can be attributed. |
| 04 | Cross-Reference & ValidationEvery conclusion is cross-referenced against independent data sources. We document the evidence base behind every finding and flag the confidence level of each conclusion — high confidence, assessed, or speculative. |
| 05 | Reporting & HandoffEvery investigation ends with a structured report. The format depends on the intended recipient: technical findings for security teams, executive summaries, evidentiary packages for legal proceedings, or structured intelligence for law enforcement. |
Working With Authorities We Know How to Work With Law Enforcement. | 🛡️ [Graphic: Law Enforcement / Shield / Evidence] Tip: If you are considering legal action following a cyber incident or fraud, engage an investigation team before you begin incident remediation. Evidence preservation decisions made in the first hours determine what is available weeks later. |
Organizations engage Karen IT for cyber investigation when they need to understand not just the technical details of an attack, but its origin, its scope, and the identity of those responsible. Common triggers include:
We discovered we were being impersonatedFake domains, lookalike websites, or fraudulent social media profiles using your brand. You need to know how many exist, who registered them, and whether they are part of a coordinated campaign before taking action. | We were targeted by a phishing campaignYour customers, employees, or partners received phishing communications. You need to understand the infrastructure behind the campaign, identify the actor, and build intelligence for takedown and law enforcement referral. |
We suffered a breach and want to know whoFollowing an intrusion, organizations want to know who was responsible to understand if they remain a target, if their sector is at risk, and what the attacker was ultimately trying to accomplish. | We are being targeted by organized fraudFinancial fraud, payment diversion, or account takeover at scale often connects to known actors or criminal networks. Understanding those connections changes both the defensive response and legal options. |
We need to support a legal or regulatory processCivil litigation, regulatory investigations, and insurance claims all require documented technical findings. Our investigation output is structured from the outset to meet these requirements. | We believe our infrastructure is being abusedRegistrars, hosting providers, and platforms that discover their infrastructure is facilitating cybercrime need rapid investigation to support takedown decisions and communications. |
Cyber investigation is difficult, time-consuming, and specialist work. The organizations that pursue it successfully are the ones that engage the right capability early — before evidence degrades, before the actor moves their infrastructure, and before the window for law enforcement action closes.
