We’ve seen that there are a lot of free automated malware analysis tools out there. It’s just a matter of choosing one and using it. But all the above solutions didn’t actually detect anything else than just the IP address the malware tried to connect to. We must also mention that when the Meterpreter executable is being run, it will actually download the secondary shellcode and run that to spawn a reverse Meterpreter shell. None of the above alternatives were able to figure that out, so we can’t replace static analysis/reverse-engineering with one of the solutions mentioned above. When the first analysis is over, we must still reverse-engineer the malware sample if we want to obtain more information about what it actually does.

 Additional information is also available, such as registry read/written registry values that can prove valuable when trying to understand the malware logic. We can also try to change the value of the registry before trying to run the malware sample, but this will result in guessing only. It’s much better to actually reverse-engineer the executable to find the exact values that need to be written in specific registry keys for malware to take different path of execution. But the list of used registry keys is still useful, because it informs us that the malware sample uses registry keys to make certain decision about its execution path.
 In response to this evolution, new, more advanced technology is emerging; including smarter, more comprehensive sandbox solutions. These sandboxes also use deep behavior analysis, but unlike their more traditional predecessors, they more closely replicate a user’s environment, such as a system configuration.
 GitHub is our main development platform. Our organization is located here. You will find multiple repositories there, mainly: Cuckoo, the main repository where we commit our progress on the project. Monitor, a separated repository used to develop the Windows analysis core, if you're interested in the internals of our hooking system. Community, which is intended to be a repository open to the community where you can find modules and signatures developed by our users.
 This is unusual; why can’t the VirusTotal detect and malware presence in the submitted sample? The Meterpreter executable should be detected as malicious, since it is exactly that. Have you ever tried to submit a Meterpreter executable to a penetration test customer, but couldn’t, since the Antivirus product instantly blocked it as malicious? So the Meterpreter should be flagged as malicious, but is not. The reason is probably because the GFI Sandbox is using only the hash when pulling the information from VirusTotal. But that technique won’t work in our case, since we created a new executable with an arbitrary IP address, which is why the hash is different and probably not in VirusTotal database. If we upload the meterpreter.exe to VirusTotal, we can see that 34 out of 45 Antivirus products detected the Meterpreter as malicious as we can see on the picture below:
 A few days later, an unexpected answer comes down from the security firm that your company hired to investigate the incident: Hackers got in by exploiting a flaw in the corporate antivirus program installed on your computer, the same program that's supposed to protect it from attacks. And all it took was for attackers to send you an email message that you didn't even open.
 The same can be said for other anti-malware techniques such as web filtering, IP reputation and antivirus. They typically rely on signatures, reputation or heuristics. This renders them ineffective against new, unknown threats.

 Effectively addressing vulnerabilities is more complicated than using just one technology, according to Kaspersky Lab. The company implements the technologies it believes will provide the best level of protection to customers. For example, it's using machine learning algorithms to leverage the large amount of security intelligence and knowledge that it acquires.
 Your best bet is to use an environment (eg FireFox) in which eval() can be overridden by using a proxy function, and the function just prints the output. That way, there is no risk in missing anything, even if the malware aliases it. Unfortunately, eval() is not designed to be overridden (and I believe is explicitly forbidden by recent ECMAScript spec), but at worst it will fail to run.
 Soon after the submission, the report will be sent to the email address provided. If you don’t receive the report after a while, check the spam folder, as the email will probably be saved in there.
 A cyberespionage group known as Careto or The Mask, perhaps state-sponsored, is known to have attempted to exploit a vulnerability in older versions of Kaspersky antivirus products in order to evade detection. The group compromised computers belonging to hundreds of government and private organizations from more than 30 countries before its activities were exposed in February 2014.
 Sandboxes have been used in recent years for malware detection because they can analyze suspicious files in a controlled environment that’s isolated from the network. Essentially, a sandbox “coerces” malicious files into executing itself, so it can be exposed and even destroyed.
 Eiram wouldn't go so far as to say that antivirus products have no place anymore. He agrees that many users, both at home and within corporate environments, still need to be protected from their own actions, like downloading risky software or clicking on malicious links.
 Network perimeter protection is also important in defending corporate environments both from outside and inside threats, like data exfiltration attempts. However, users should not assume that network-level security appliances don't have vulnerabilities. In fact, security researchers have found a large number of flaws in these products as well over the years, and exploits for them are also being sold on the unregulated exploit market.
 We can see the MD5, SHA1, and SHA256 hash of the submitted file. Below is the link, which we can click to go to results. Keep in mind that you will be automatically redirected when the analysis is complete and the results are generated. Once we’ve been redirected to the specified URL, the following will be presented to us:
 Symantec is working to reduce the attack surface of its products and services. Its approach, the company said, is to operate its security components at the lowest privilege level possible to reduce the likelihood of a successful attack.
 After that, we need to copy the executable to some Windows virtual machine on the same subnet as the IP 192.168.1.130 and execute it. The Meterpreter session should be established successfully, as can be seen in the output below:

 You need to have good knowledge on the internals of the sandbox, use it, play with it and understand it at its deepest components. After having dissected it enough, you'll surely have some patches or features you want to add.
 This will start our default web browser, which we can then use to browse the Internet. Keep in mind that every file downloaded by the default browser (either automatically by the browser itself or manually by us) will be sandboxed. When the default browser starts, we can download the putty.exe program from the Internet, as shown in the picture below:
 Even worse, evidence suggests that many antivirus products are not even properly audited for security flaws, Koret said. "For example, looking at the vulnerabilities discovered by Tavis Ormandy, it's absolutely clear that they never audited the software at all because such vulnerabilities would be detected by an auditor during the first assessment in, probably, one week."
 Claudio is our Willy Wonka, the undisputed dictator of the project. He writes code that doesn't work and he expects others to fix it. He likes long walks on the beach, reading a good book and messing with cybercrooks and cyberspooks. For an extreme abundance of bragging, you can check his bio here.
 Whenever we decide that we would like to upload a malware sample to be analyzed outside of our environment, we must be aware of the fact that the malware sample can be publicly disclosed by a third party. But the story doesn’t end there: let’s say we’ve gotten our hands on some malware sample that isn’t well known yet and we want to reverse-engineer it and publish our findings. This is all fine and dandy, but if the malware is publicly disclosed, the attacker might notice that something is going on. The attacker can become aware of the fact that his/her malware sample has become known and is being reverse-engineered by the reverse-engineers. This might cause a lot of actions on behalf of the attacker to try to prolong the malware sample from becoming well known and thus being detected and removed from the systems with antivirus programs, IDS or IPS solutions. It is certainly a good thing for the attacker to be aware of the fact that his malware has been publicly disclosed, so he can take actions based on that.
 Many thanks to @grecs for his additions and helping me to organize it. Also to Lenny Zeltzer, author of the REMnux malware analysis and reverse engineering distro, who I’ve borrowed shamelessly from. You’ll find many of these tools and others on his own lists, so I encourage you to check his posts on this topic as well.
 As always, success with either of the tools is not guaranteed, but who knows. In the end, you might be more interested in a dynamic approach, such as patching eval as described above.
