Viper alternatives

In a matter of seconds, Cuckoo Sandbox provides detailed results on what a file does within an isolated environment. This helps with malware analysis and understanding what it exactly tries to achieve. Further analysis can be done, based on the previous actions that were done.

Cuckoo Sandbox was created by Claudio Guarnieri as part of the Google Summer of Code project in 2010.

Malice is a malware analysis that wants to provide a free and open source version of VirusTotal. The goal of Malice is to make it usable by both independent researchers up to fortune 500 companies.

Malice is useful for those that do malware analysis or deal with user-generated files that may contain malware. The framework allows scanning files and directories to see if they are infected.

BANG is a framework to unpack files recursively and scan them. The files can be firmware, binaries, or malware. The main goal is to scan all files and perform classification and labeling. This way each file can be further analyzed based on the characteristics.

Mal Tindex is a tool that performs binary analysis on malware samples. It analyzes the binaries it is provided to learn about the specifics of each malware sample that makes them unique. This way data can be gathered that may provide background information. For example, it could provide the attribution of a particular actor or malware campaign.

MultiScanner helps malware analysts by providing a toolkit to perform both automated and manual analysis. The data extracted from the analysis can be easily stored together, including the relevant metadata and samples. It allows enriching the data further by retrieving information from external resources.

SSMA is short for Simple Static Malware Analyzer. The tool can perform a set of tests against a malware sample and retrieve metadata from it. SSMA can analyze ELF and PE and analyze its structure. For example, it can retrieve the PE file header information and its sections. Other pieces it can analyze is the usage of packers, anti-debugging techniques, cryptographic algorithms, domains, email addresses, and IP addresses. It can also check if the sample is already detected or blocked by using VirusTotal and the blocklist of malwaredomains.com.

YaraGuardian provides a web-based interface that helps to manage Yara rules. It can be used to search, organize, and bulk-edit rules. The tool also prevents creating duplicate entries, which is a nice additional benefit of this management utility.

Searches through binaries and highlights the most important areas with colors.

Supported binary formats:

• ELF 32/64, arm, x86, openrisc
• Mach 32/64, arm, x86
• PE

This tool is useful to time scans, for example by having it run outside of business hours, and stop when the day starts.

Note: originally another tool was named AutoNessus. That is now Seccubus.

Supported engines and tools:

• Nessus
• OpenVAS
• Nmap
• Nikto
• Medusa
• Qualys SSL labs
• SkipFish
• SSLyze
• testssl.sh
• ZAP

SpiderFoot can be used offensively during penetration tests, or defensively to learn what information is available about your organization.

Tools like pick are used to store passwords and secrets safely.

Pshtt was developed to push organizations, including government departments, to adopt HTTPS across the enterprise.

ClamAV is a popular tool to detect malicious software or malware. While it calls itself an antivirus engine, it probably won't encounter many viruses, as they have become rare. It is more likely to find other forms of malware like worms, backdoors, and ransomware. ClamAV can be used in a few ways, from doing an occasional scan up to scanning in batch. ClamAV does not do on-access scanning but can be combined with other tools to obtain similar functionality. ClamAV is often used to support scanning incoming emails for malicious content.

Rootkits are typically considered to be malware, or malicious software. With the intent to hide, this type of software is often used after a breach. Learning about how it works can be useful for security researchers and security professionals.

LMD uses MD5 file hashes and HEX pattern matches to define the malware signatures. These are used to detect malware.

Malscan is a tool to scan for malicious software (malware) such as viruses, worms, and backdoors. Its goal is to extend ClamAV with more scanning modes and signatures. It targets web servers running Linux, but can also be used on mail servers and desktops.

Rootkit Hunter is a small utility to find suspicious rootkit components. Other known backdoors or malicious software can also be discovered, especially if it has the goal to hide.

The tool uses different ways to hunt, like using predefined directory locations and comparing the output of system utilities. Another method is by requesting a specific output and see if this output is altered, therefore tricking rootkits to reveal themselves.

The chkrootkit tool consists of multiple parts that may detect the presence of rootkit parts of rootkit behavior on a system.

Some areas that are checked include:

• interface in promiscuous mode
• lastlog deletions
• wtmp deletions
• wtmpx deletions
• signs of LKM trojans
• utmp deletions

For the privacy-aware users, tools like hBlock can be helpful to block malicious domains, malware, advertisements, and trackers. Trackers could be pixels added to websites to track which pages you visited, which might invade your privacy.

Cutter is a graphical user interface for radare2, the well-known reverse engineering framework. It focuses on those who are not familiar enough with radare2, or rather have a graphical interface instead of the command-line interface that radare2 provides.

LIEF is short for Library to Instrument Executable Formats.
