Malware variants still increase at an alarming rate since the arrival of ransomware and other financial malware. you want to have right tool so as to analyse these malware samples. during this article, we’ll explore best malware analysis tools to review behavior and intentions of malware.
Malware Analysis Techniques
It is the method of analyzing a malware sample without actually running the code. this is often accomplished through two techniques:
Signature based technique – Malware detector looks for known pattern matching within the signatures.
Heuristic detection – rather than trying to find a specific , known signature, the malware detector is checking out commands and directions that aren’t present within the application .
It is the method of analyzing malware by running the sample then studying its behaviour and intentions. this is often administered during a closed and isolated environment either virtual machine or Sandbox.
This kind of study involved both static and dynamic techniques. Initially, code is analysed without running the sample then its behaviour is studied.
Malware Analysis Tools
When malware is executed, it dramatically makes changes to system environment. This includes modification of core system files, registry keys and other settings. It can cause damage to the system wont to perform test.
Sandbox solves this problem by providing isolated environment to run malicious samples without worrying of getting damaged. Any impact of malware run in virtualized sandbox doesn’t impact the particular system.
However, some malware are clever enough to detect being run in sandbox. they are doing not execute in malicious thanks to trick the analysts. So, analysis must be through with proper care and emulation must be done to match actual system configuration.
Cuckoo Sandbox is one among the favored and reliable program to make sandbox. It’s an open source platform that automates malicious file analysis for Windows, OS X, Linux and Android and provides detailed and meaningful feedback regarding how each file presented behaves in isolated environments.
Behavior Analysis Tools
In the initial days, malware analysis was administered by matching against the file signature of known malware database. If the file doesn’t match any signature present within the database, it had been considered to be safe. However, with the rapid development of malware and massive variants being pushed into the internet , this method became obsolete.
To combat the matter , Behavior analysis tools were introduced which don’t believe signature. Rather, they monitor the processes and events on the machine and notify user if certain behavior seems to be suspicious. An example might be rapid modification of core registry keys or changes to security settings.
Sophisticated, modern tools use AI to spot patterns that human analyzers might not see, like files being rapidly modified, or the system itself being altered.

Reverse Engineering Tools
Reverse engineering may be a complex analysis method. it’s generally administered manually and impossible to be a neighborhood of automated testing environment. It involves use of a debugger, disassembler, and other specialized tools to trace back content of the computer virus . Some popular tools are:
- Jad Debugger
Network Traffic Analysis
In this method, computer virus is identified through their actions, instead of through identifying characteristics of the program itself. Network traffic analysis focuses on the network activities like file being uploaded across the network or downloaded or encrypted at the speed which is unusual.
Just like behavior analysis, analyst can learn by observing network activities. This method is simpler when utilized in combination with malware behavior analysis. Some sophisticated malware could be modified to seem legit but their actions can’t be hidden. When anomaly is detected in network usage or some program’s behaviour, it are often cross checked to verify detection.
One of the favored tool is Zeek. it’s a strong network-based analysis framework that turns network traffic into events to trigger scripts. Zeek makes use of both signature based and behavior based analysis to offer a bird’s eye-view of network activity. this will even be wont to conduct forensics investigations, network monitoring and protocol analysis.
Analysing of threats isn’t enough, we must also influence it. an honest malware analysis tool can detect also as provide elimination or remedy for it. Malware reaction time is inversely proportional to the quantity of injury . reaction time should be as fast as possible to avoid any severe damage.
Yara is an open source malware attribution tool wont to classify malware samples supported textual or binary patterns once they need been analyzed in Sandbox. Analysts can write descriptions of malware families supported patterns using Yara. It allows researchers to acknowledge and categorize seemingly similar variants of malware.
Google Rapid Response
GRR is employed to analyse malware footprints at specific workstation. Incident response team can perform various forensic tasks on the client machine, like analyzing the memory, searching various settings and managing configuration options. Using these combination of tools, we create an ultimate malware detection tool.
