Our Malware Analysis services help you understand the behavior, capabilities, and impact of malicious software, enabling effective incident response and threat intelligence.
ReactiveZero's Malware Analysis services provide in-depth examination of malicious software to understand its functionality, origin, and potential impact. Our experts use static and dynamic analysis techniques to dissect malware samples, extract indicators of compromise (IOCs), and develop effective mitigation strategies.
Each sample follows one pipeline: contained intake, three lanes of analysis that inform each other, and an actionable verdict.
The sample arrives encrypted, is hashed and fingerprinted, and stays in an isolated lab with no route to your estate.
Without executing it, we strip packers, recover strings and imports, and match the code against YARA rules and known families.
The sample runs in instrumented sandboxes with simulated internet, recording process trees, dropped files, registry changes and command-and-control traffic.
Where sandboxes fall short, we disassemble and debug the code to recover its configuration, cryptography, evasion tricks and true capabilities.
The verdict, ATT&CK mapping and detection content — hashes, domains, YARA and Sigma rules — are packaged for your SOC and EDR.
Static and dynamic lanes run in parallel; reverse engineering is scoped to what the verdict needs.
t+ = time since intakeWhen ransomware hits, understanding it quickly shapes your entire response. We analyse the sample to identify the family and variant, map its encryption scheme, and determine how it spreads, achieves persistence and communicates with command-and-control. Where a flawed implementation allows it, we assess the prospect of decryption without paying. You receive the indicators of compromise, affected file types and behaviour needed to scope the incident, contain the spread and brief leadership — work that dovetails directly with our incident response and digital forensics teams.
Remote access trojans and stealthy backdoors are built to stay hidden while an attacker keeps control of your systems. We dissect the sample through static and dynamic analysis to reveal its capabilities — keylogging, screen capture, credential theft, lateral movement and data exfiltration — and to expose its command-and-control channels and evasion tricks. The result is a clear picture of what the malware can do and what it may already have done, plus IOCs and detection rules your team can deploy to find and remove every instance.
Advanced persistent threats use custom malware and rootkits designed to defeat ordinary defences and survive reboots and re-imaging. We perform deep reverse engineering to understand these implants: their kernel- or firmware-level footholds, anti-analysis techniques, staged payloads and long-term persistence. We map observed behaviour to the MITRE ATT&CK framework so you can reason about the adversary and their objectives. You receive a detailed technical report, IOCs and detection guidance to support attribution, eradication and a hardening plan that closes the door behind them.
Malicious mobile apps target the credentials, banking sessions and personal data on Android and iOS devices. We analyse suspicious APKs and IPAs to understand what they collect, how they abuse permissions and accessibility services, and how they talk to their operators. Static and dynamic analysis reveal obfuscation, dropper behaviour and exfiltration channels. You receive IOCs, a plain-language behaviour report and practical guidance for your mobile fleet — findings that complement our mobile application penetration testing when a legitimate app is the target rather than the threat.
