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.
Identifying who is responsible — built from corroborated technical indicators
Tracing the full operational footprint of a threat actor's network
Full campaign analysis — kit, infrastructure, actor, and related domains
Full attack chain investigation across multiple jurisdictions
Scope, attribution, and evidence for takedown and legal action
C2 mapping, actor correlation, and disruption coordination
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.
Focused 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.

Investigation connects the dots across infrastructure, registrar records, threat intelligence databases, behavioral patterns, and historical data to identify threat actors and build a picture that supports attribution and action.

Mapping and disrupting the infrastructure behind malware campaigns
Every investigation begins with a defined scope and objective. We do not conduct open-ended fishing exercises. Each engagement has a clear question we are working to answer, and a defined standard of evidence the output must meet.
Before any analysis begins, we establish what you are trying to determine and what you will do with the findings — law enforcement referral, civil legal action, takedown, or threat assessment. The end use shapes the methodology, the documentation standard, and the depth required.
We begin with what is known — a domain, an IP address, an email header, a malware sample, a phishing URL, or any other initial indicator. These seeds are systematically expanded using our CTI platform, passive DNS, WHOIS correlation, certificate transparency logs, and open-source intelligence — always with a documented reasoning chain.
As the indicator set grows, patterns emerge — infrastructure clusters, registration timing, shared hosting, certificate relationships, behavioral signatures. We analyze these patterns to build a picture of the actor's operational methodology: how they set up, how they operate, how they move when disrupted, and what they leave behind.
Every conclusion is cross-referenced against independent data sources before inclusion in the investigation output. We do not make attribution claims based on single indicators. We document the evidence base behind every finding and flag the confidence level — high confidence where multiple sources corroborate, assessed where consistent but not conclusive, speculative where noted as hypothesis.
Every investigation ends with a structured report — technical findings for security teams, executive summaries for leadership, evidentiary packages for legal proceedings, and structured intelligence for law enforcement submission. Where the investigation has generated actionable takedown intelligence, we coordinate submission and execution of takedown requests in parallel with the final report.
Many organizations that experience cybercrime want to pursue legal action but don't know how to bridge the gap between their security team and the relevant law enforcement authorities. The gap is real.
Law enforcement agencies have specific requirements for how evidence must be collected, preserved, and submitted. Material that is not prepared to these standards — however technically accurate — will not be usable. Karen IT has established working relationships with national and international law enforcement bodies and structures our engagements accordingly from the outset.
Evidence packaging for law enforcement submission — structured, documented, and meeting chain-of-custody requirements
Technical liaison — translating complex technical findings into formats that investigators and prosecutors can work with
Cross-border coordination — identifying the correct jurisdictional authority and supporting the referral process
Coordination with INTERPOL, Europol, national CERTs, and regional cybercrime units where relevant to the case
Ongoing case support — providing additional analysis as an investigation develops on the law enforcement side
Organizations engage Karen IT for cyber investigation when they need to understand not just the technical details of an attack, but its origin, scope, and the identity of those responsible.
Fake 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 you can take effective action.
Your customers, employees, or partners received phishing communications impersonating your organization. You need to understand the infrastructure behind the campaign and build the intelligence needed to support takedown.
Following an intrusion, many organizations want to know who was responsible — to understand whether they remain a target, whether their sector is at risk, and what the attacker was ultimately trying to accomplish.
Financial fraud, payment diversion, or account takeover at scale often follows patterns that connect to known actors or organized criminal networks. Understanding those connections changes both the defensive response and the options for legal recourse.
Civil litigation, regulatory investigations, and insurance claims all require documented technical findings. Our investigation output is structured from the outset to meet these requirements.
Registrars, hosting providers, and technology platforms that discover their infrastructure is being used to facilitate cybercrime need rapid, technically authoritative investigation to support takedown decisions.
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 action closes.
