Malware analysis Africa

Malware analysis Africa

Cyber threats are becoming more sophisticated across Africa as businesses, government institutions, financial organisations, technology companies, educational institutions and individuals continue to adopt digital platforms. From internet banking and mobile applications to cloud services, e-commerce, digital payments, remote work and online communication, Africa’s digital transformation is creating enormous opportunities while also expanding the attack surface available to cybercriminals.

One of the most serious components of this threat landscape is malware.

Malware—short for malicious software—includes ransomware, spyware, trojans, worms, information stealers, banking malware, remote-access trojans, backdoors, botnets, malicious scripts and other software designed to compromise systems, steal information, disrupt operations or provide unauthorised access.

For organisations operating in Africa, detecting malware is only the beginning. Security teams need to understand what the malware does, how it entered the environment, what systems it targets, what information it attempts to access, how it communicates with attackers and whether other systems may have been compromised.

This is where professional malware analysis becomes essential.

Deejoft Cybersecurity provides malware analysis and cybersecurity services designed to help organisations across Africa understand, investigate and respond to suspicious files, applications, processes and malicious activities. Our approach combines static analysis, dynamic analysis, behavioural investigation, threat intelligence and security expertise to help organisations make informed decisions during malware investigations and security incidents.

Africa’s cyber threat environment requires stronger detection and investigation capabilities. INTERPOL’s African Cyberthreat Assessment Report identified malware attacks—including ransomware, banking trojans and information stealers—among the prominent cyber threats affecting the continent. The report also highlights the increasing sophistication of social engineering, phishing, data theft and cybercrime-as-a-service.

Recent threat research also shows that African organisations continue to face substantial attack pressure. Check Point’s 2025 African cybersecurity report reported an average of 3,153 attack attempts per organisation per week in Africa compared with 1,963 globally, while 80% of malicious files observed in its data were delivered through email.

These developments demonstrate why organisations cannot rely exclusively on traditional antivirus software or perimeter security.

What Is Malware Analysis?

Malware analysis is the process of examining suspicious or malicious software to understand its functionality, behaviour, capabilities, indicators of compromise and potential impact.

A malware analyst investigates a suspicious file or program to answer important security questions.

For example:

• What does the file do?
• Is the file actually malicious?
• What type of malware is it?
• Which operating systems does it target?
• What files does it create or modify?
• Does it establish persistence?
• Does it communicate with external servers?
• Does it attempt to steal credentials?
• Does it collect sensitive information?
• Does it encrypt files?
• Does it download additional malware?
• Does it provide remote access?
• What domains, IP addresses or URLs does it contact?
• What indicators can security teams use to detect the threat?
• Could the malware have affected other systems?
• What actions should the organisation take?

Malware analysis therefore goes beyond simply identifying a malicious file.

It provides security intelligence that can support incident response, threat hunting, digital forensics, endpoint protection and long-term security improvement.

Why Malware Analysis Is Important in Africa

African businesses are rapidly adopting digital technologies.

Banks and fintech companies are processing digital transactions. Hospitals are storing sensitive patient information electronically. Universities are operating online learning platforms. Government agencies are digitising public services. Businesses are using cloud platforms and remote collaboration tools.

At the same time, cybercriminals are targeting these environments.

INTERPOL has reported that ransomware, business email compromise and online scams are among the major and growing cyber threats affecting African countries.

The African Union has similarly recognised the increasing impact of cybercrime and the importance of strengthening cybersecurity capabilities as digital infrastructure expands across the continent.

Malware can become particularly dangerous when organisations do not have sufficient visibility into their systems.

A suspicious attachment may initially appear to be an ordinary document. A compromised application may appear legitimate. A malicious executable may remain dormant for a period before activating. A stolen credential may be used to gain access without triggering traditional malware alerts.

Professional malware analysis helps security teams investigate these situations systematically.

Malware Analysis Services by Deejoft Cybersecurity

Deejoft Cybersecurity provides malware analysis services for businesses and organisations that need to investigate suspicious software, files, applications and security incidents.

Our services can support organisations before, during and after a cybersecurity incident.

1. Suspicious File Analysis

If your organisation receives a suspicious executable, document, archive, script or other file, our cybersecurity team can analyse it to determine whether it presents a security threat.

Suspicious files may originate from:

• Email attachments
• Downloaded software
• USB devices
• Websites
• Messaging platforms
• Cloud storage
• Third-party applications
• Compromised websites
• Internal systems
• Security incident investigations

The objective is to determine whether the file exhibits malicious characteristics and identify useful indicators for detection and response.

2. Static Malware Analysis

Static analysis examines a malware sample without executing it.

Depending on the sample, analysts may examine file characteristics, metadata, embedded information, strings, imports, executable structures, hashes, packing characteristics and other artefacts.

Static analysis can provide valuable information about a suspicious program while reducing the risks associated with executing unknown code.

It can help analysts identify potential functionality, suspicious components and relationships with known malware families.

3. Dynamic Malware Analysis

Dynamic analysis involves observing the behaviour of suspicious software within a controlled and isolated environment.

The objective is to understand what the sample actually does when executed.

Depending on the investigation, analysts may observe:

• Process creation
• File-system activity
• Registry modifications
• Network connections
• DNS requests
• Persistence mechanisms
• Application behaviour
• System changes
• Configuration changes
• Attempts to access sensitive resources

Dynamic analysis can provide behavioural intelligence that may not be obvious from static examination alone.

4. Malware Behaviour Analysis

Understanding malware behaviour is critical to developing effective defensive controls.

Our analysts investigate how malware behaves and what actions it attempts to perform.

For example, a malicious program may attempt to establish persistence, communicate with command-and-control infrastructure, collect information or download additional components.

Understanding these behaviours can help organisations develop better endpoint detection and response rules, firewall controls, SIEM alerts and threat-hunting queries.

5. Ransomware Analysis

Ransomware can cause severe operational and financial disruption.

A ransomware investigation may involve analysing the malware responsible for encrypting files, identifying its behaviour, determining potential indicators of compromise and helping the organisation understand the attack chain.

Our malware analysis services can support incident response teams investigating ransomware incidents and suspicious encryption activity.

We focus on understanding the malware and producing actionable intelligence that can support containment, recovery and future prevention.

6. Banking Malware and Financial Malware Analysis

Africa’s growing digital financial ecosystem has created valuable targets for cybercriminals.

Financial malware may target banking credentials, authentication information, payment data and other sensitive information.

Malware analysis can help financial institutions, fintech companies and businesses investigate suspicious applications and malicious files associated with financial attacks.

7. Information Stealer Analysis

Information stealers are malware families designed to collect sensitive information from compromised systems.

Depending on the malware, stolen information may include credentials, browser data, session information or other sensitive information.

Our analysts can examine suspicious samples to understand their collection and communication behaviour and identify indicators that can help organisations detect related activity.

Kaspersky’s 2025 Africa Cyberthreat Landscape Report reported significant increases in password-stealer and spyware detections in African B2B environments during Q1 2025, highlighting the importance of stronger detection and investigation capabilities.

8. Trojan and Backdoor Analysis

Trojans and backdoors can provide attackers with unauthorised access to systems.

A backdoor may allow an attacker to maintain access after the initial compromise.

During analysis, security researchers may investigate the sample’s capabilities, communication behaviour, persistence mechanisms and other relevant characteristics.

The resulting intelligence can help organisations identify affected endpoints and strengthen defensive controls.

9. Remote Access Trojan Analysis

Remote Access Trojans, commonly known as RATs, can provide attackers with extensive control over compromised systems.

Depending on their capabilities, RATs may allow attackers to monitor activity, execute commands, access files or communicate with remote infrastructure.

Our malware analysis process can help organisations understand the functionality of suspicious RAT samples and develop appropriate detection and containment strategies.

10. Malware Family Identification

Identifying the malware family can help security teams understand the threat more quickly.

Malware classification can provide useful context regarding known behaviours, capabilities, indicators and potential attack patterns.

However, malware identification should not rely solely on naming the malware family.

A modern investigation should also examine the specific sample and its observed behaviour because attackers frequently modify malware and customise campaigns.

Our Malware Analysis Methodology

At Deejoft Cybersecurity, malware analysis follows a structured investigation process.

Stage 1: Sample Collection

The investigation begins by securely collecting the suspicious file or relevant artefacts.

We establish the source and context of the sample where available.

Important information may include:

• Where the file was discovered
• When it was discovered
• Which system received it
• Which user interacted with it
• How the file was delivered
• Whether similar files exist
• Whether suspicious activity was observed

Context can be extremely valuable during malware investigations.

Stage 2: Triage

The sample undergoes an initial assessment to determine its characteristics and potential risk.

Triage helps determine the appropriate depth of analysis and prioritise urgent threats.

Stage 3: Static Analysis

Analysts examine the sample without executing it.

This stage can reveal useful information about the file’s structure and potential capabilities.

Stage 4: Controlled Dynamic Analysis

Where appropriate, the sample may be analysed within an isolated research environment.

The objective is to observe behaviour without exposing production infrastructure.

Stage 5: Network Behaviour Investigation

Analysts examine relevant network behaviour associated with the sample.

This may include identifying suspicious domains, IP addresses, DNS activity, URLs and other indicators.

Stage 6: Indicator Development

The investigation can produce Indicators of Compromise, commonly known as IOCs.

These may include:

• File hashes
• Domains
• IP addresses
• URLs
• File paths
• Registry artefacts
• Process names
• Mutexes
• Other relevant artefacts

IOCs can help security teams search their environments for related activity.

Stage 7: Reporting

The final stage involves documenting findings and providing actionable recommendations.

A professional malware analysis report may include:

• Executive summary
• Malware classification
• Sample information
• Technical findings
• Behavioural analysis
• Network indicators
• Host indicators
• Risk assessment
• Potential impact
• Detection recommendations
• Containment recommendations
• Remediation recommendations

Malware Analysis for Nigerian Businesses

Nigeria is one of Africa’s largest digital markets, with substantial activity across fintech, banking, telecommunications, e-commerce, logistics, healthcare, education, government and technology.

This makes Nigerian organisations attractive targets for cybercriminals.

Businesses operating in Nigeria may encounter malware through phishing emails, compromised websites, malicious downloads, infected removable media, fraudulent software, compromised credentials and other attack vectors.

Kaspersky’s Africa threat research specifically highlighted Nigeria among countries experiencing rapid digital adoption while warning that the expansion of cloud services and mobile devices can widen the attack surface when security controls do not keep pace.

Deejoft Cybersecurity helps Nigerian organisations investigate malware and strengthen their security posture through professional security testing, threat analysis and incident investigation.

Africa’s cybersecurity environment is diverse. Organisations have different regulatory requirements, technology environments, risk profiles and levels of cybersecurity maturity.

Our approach is therefore designed to focus on the organisation’s specific environment and security objectives.

Who Needs Malware Analysis?

Malware analysis can benefit organisations of different sizes and industries.

Banks and Financial Institutions

Financial organisations handle valuable information and transactions, making them attractive targets.

Malware analysis can help investigate suspicious applications, endpoint infections, banking malware and other threats.

Fintech Companies

Fintech organisations depend heavily on APIs, cloud platforms, mobile applications and digital identity.

A malware incident can create financial, operational and reputational consequences.

Government Agencies

Government systems may contain sensitive citizen information and support critical public services.

Malware investigations can help government security teams understand compromises and strengthen defensive controls.

Healthcare Organisations

Hospitals and healthcare providers store sensitive information and depend on technology for daily operations.

Malware, particularly ransomware, can disrupt critical services.

Educational Institutions

Universities and schools increasingly depend on digital systems, student portals, learning management systems and cloud platforms.

These environments can become targets for malware and credential theft.

SMEs

Small and medium-sized businesses are often targeted because they may have limited cybersecurity resources.

A malware incident can interrupt operations, expose sensitive information and create significant recovery costs.

Professional analysis can help smaller organisations understand incidents and improve their security controls.

Malware Analysis and Incident Response

Malware analysis is often an important component of incident response.

When an organisation discovers suspicious activity, the key question is not simply:

“Is this malware?”

Security teams also need to ask:

“What happened, how far did the attacker get, and what should we do next?”

Malware analysis can contribute to answering these questions.

For example, identifying a malware sample and its associated indicators may allow defenders to search other endpoints for evidence of the same threat.

This can help determine whether the incident is isolated or part of a wider compromise.

Threat Intelligence From Malware Analysis

Every malware investigation can produce valuable intelligence.

Instead of treating a suspicious file as an isolated incident, security teams can extract information that can improve the organisation’s broader security posture.

Threat intelligence from malware analysis may help organisations:

• Improve detection rules
• Strengthen endpoint monitoring
• Update security policies
• Block malicious infrastructure
• Develop SIEM alerts
• Improve threat-hunting processes
• Identify attack patterns
• Improve employee awareness
• Strengthen incident response procedures

This transforms malware analysis from a reactive activity into a proactive security capability.

Malware Analysis and Threat Hunting

Threat hunting involves proactively searching an environment for signs of malicious activity.

The indicators identified during malware analysis can become useful inputs for threat-hunting exercises.

For example, if malware analysis identifies a suspicious domain or file hash, security teams can investigate whether the same indicator appears elsewhere within the organisation.

This can help identify previously undetected infections.

Malware Analysis for Cybersecurity Teams

Organisations with internal IT or cybersecurity departments can also use specialist malware analysis services to supplement their capabilities.

Not every organisation has dedicated malware researchers, reverse engineers or threat intelligence specialists.

External cybersecurity expertise can provide additional technical depth when an internal team encounters a complex sample.

Deejoft Cybersecurity can work alongside internal security teams to provide analysis and technical findings while allowing the organisation to retain control over its broader incident response process.

Protect Your Organisation From Malware

Malware threats are constantly evolving.

Cybercriminals modify existing malware, develop new variants, abuse legitimate tools and combine malware with phishing, stolen credentials and social engineering.

This means organisations need more than a single security product.

They need visibility, detection, investigation and response capabilities.

The 2026 Africa cybersecurity outlook from EY describes cyber risk across Africa as increasingly systemic, with identity, data and digital trust becoming major attack surfaces.

Malware remains an important component of this broader threat landscape.

Organisations should therefore establish procedures for identifying suspicious files, isolating compromised systems, preserving evidence and investigating malicious activity.

When Should You Request Malware Analysis?

You should consider professional malware analysis when:

• An employee opens a suspicious attachment.
• Antivirus software detects an unknown threat.
• A suspicious executable appears on a company computer.
• An endpoint begins behaving unusually.
• A server makes unexpected outbound connections.
• Files suddenly become encrypted.
• An organisation suspects a ransomware infection.
• Unknown software appears on company systems.
• A security team discovers suspicious processes.
• A business suspects a compromised endpoint.
• A phishing campaign delivers suspicious files.
• A security incident requires technical investigation.
• An organisation wants to understand a malware sample.
• A SOC team needs additional threat intelligence.

Early investigation can provide valuable information for containment and response.

Building a Stronger Malware Defense Strategy

Malware analysis should be part of a broader cybersecurity strategy.

Organisations should combine:

Endpoint Security + Email Security + Network Monitoring + Identity Protection + Vulnerability Management + Security Awareness + Threat Intelligence + Incident Response + Malware Analysis

No single security control can prevent every cyberattack.

A layered approach makes it more difficult for attackers to compromise systems and can improve an organisation’s ability to detect and respond when prevention fails.
