Incident response · Malware, phishing and fraud analysis

Malware and electronic fraud analysis

When something has already happened, the first thing you need is an accurate account of what it was. We analyse suspicious files, phishing campaigns and network traffic, and tell you what the attacker did, what they reached, and what to do about it.

What we analyse

The service is as useful for a single suspicious file as it is for a full incident — including cases of suspected fraud, account compromise, suspicious email, spoofed websites or data theft.

01 · Files

Suspicious files and malware detection

We examine the file’s behaviour, its indicators of compromise and its effect on the system, in order to establish the level of risk and the measures required.

  • viruses
  • trojans
  • ransomware
  • spyware
  • backdoors
  • malicious scripts
02 · Incidents

Security incident investigation

We establish the source of the incident, the attack method, the compromise vector, the impact on systems and data, and the measures needed to contain it and prevent recurrence — the work that matters most for organisations hit by suspicious activity, unauthorised access or account compromise.

03 · Network

Network traffic analysis

Traffic shows whether an attack is in progress or a compromise has already occurred.

  • suspicious communications
  • anomalous connections
  • unauthorised data transfers
  • signs of infection
  • command and control activity
04 · Phishing

Phishing and business email compromise

We analyse messages, emails and suspicious sites to identify phishing, spear phishing and online fraud attempts.

  • message structure
  • links and domains
  • attachments
  • social engineering elements
  • risk of data compromise
05 · Fraud

Electronic fraud analysis

Identifying and understanding the mechanisms used in banking fraud, fraud through compromised online accounts, email fraud, impersonation, identity takeover attempts, and fraudulent payment and investment schemes.

How it runs

If an incident is in progress, say so in the first line and we will prioritise it.

STAGE 1

Intake

What was seen, when, which systems are affected and what evidence still exists.

STAGE 2

Preservation

Collecting and preserving evidence before it is overwritten.

STAGE 3

Analysis

Files, traffic, messages, logs — establishing the vector and the impact.

STAGE 4

Report

Indicators of compromise, incident timeline, remediation sequence.

STAGE 5

Prevention

The measures that stop the same scenario from repeating.

Context

Opportunistic or targeted

One of the most useful outputs of the analysis is establishing whether the incident was part of an opportunistic, broad campaign or a targeted attack. The two require different responses.

An incident that is never properly analysed tends to repeat. Establishing the entry point, the persistence mechanism and the data actually touched is also what allows you to meet reporting obligations accurately — under NIS2, a notification based on guesswork is a problem of its own.

Broad campaign
Aimed at a large number of users with no particular victim selected: mass phishing, large-scale malware distribution, automated attacks on exposed services, repeated unauthorised access attempts. The goal is volume, not the target.
Targeted attack
Planned against a specific organisation after the attacker has studied the target, its behaviour and its technology: tailored spear phishing, selective account compromise, adapted tooling, advanced social engineering, quiet operations designed to avoid detection.
Why it matters
Targeted attacks are harder to detect and pursue specific objectives — theft of sensitive data, disruption of operations, or persistent access to the infrastructure. The right response depends on which of the two it was.

When to ask for this

  • You received a suspicious file
  • You suspect a malware infection
  • You received a phishing email
  • You see unusual activity on the network
  • There are signs an account was compromised
  • A possible electronic fraud has occurred
  • You need the nature of an incident clarified
  • You have to notify the authority and need facts, not assumptions

Prevention
Security testing finds the vulnerabilities before they are exploited · staff training lowers the success rate of phishing.
Compliance
For organisations in scope of NIS2, the internal incident handling and reporting flow is part of the outsourced officer role and of the compliance engagement.

Frequently asked questions

01What do I do in the first minutes?

Do not delete, reinstall or “clean” the system. Isolate it from the network but leave it powered on if possible, and write down the time and what you observed. Most evidence is lost not to the attacker but to well-intentioned intervention in the first minutes.

02Can you analyse just one file or one email?

Yes. A single suspicious file or phishing message can be submitted on its own, without a broader engagement. The output is a risk assessment and, where relevant, the indicators of compromise you can then search for across the rest of your infrastructure.

03Does the analysis help with notifying the authority?

Yes. Findings are written in a form that supports notification to the competent authority: what happened, when, which systems and data were affected, and what was done about it. A notification built on assumptions creates a problem separate from the incident itself.

04What do I receive at the end?

A written analysis with the indicators of compromise identified, the incident timeline as far as the evidence supports it, and a remediation sequence — what to do first, what follows, and which measures prevent a repeat.
