What is a hashing tool

Like this article? What is Hashing? Back to Glossary. Introduction One concept that you will meet time and time again in any discussion of cybersecurity is the concept of a hash. What is a Hashing Algorithm? By default, it will use the SHA-2 algorithm: You can change to another algorithm by specifying it after the filepath with the -Algorithm switch. Passing the result to Format-List also gives a more reader-friendly output: For Mac and Linux users, the command line tools shasum and md5 serve the same purpose.

Now, we get a more accurate result indicating the files are indeed different as expected: What is Hashing Used For? Benefits of Hashes in Threat Hunting Threat hunting is also made easier thanks to hash values. Conclusion Hashes are a fundamental tool in computer security as they can reliably tell us when two files are identical, so long as we use secure hashing algorithms that avoid collisions. Your most sensitive data lives on the endpoint and in the cloud. The function then continues to parse the portable executable PE export data and passes the virtual protect hash 0xD13C to the hashing algorithm.

The same is done for the remaining hashes. This process is shown in Figure 5 with my added comments. The MASS is a distributed system designed to download, process, analyze, and index terabytes of potentially malicious files on a daily basis. I analyzed this subset of exemplars and discovered two slight variations in the API hashing routine. The first was an addition of one extra byte, while the second dealt with bit files.

However, when identifying new exemplars, I wanted to know which API hashing function was found in the exemplar. I turned my attention to identifying the sll1Add routine API hash values found in all of the 37 exemplars.

All exemplars had the sll1Add routine API hash values for functions from kernel These are shown in Figure 9. There were a few outliers that had the sll1Add routine API hash values for functions from wininet.

These are shown in Figure The API hashes shown in Figures 10 and 11 indicate that these exemplars have potential network communications. I analyzed these exemplars to identify the network-based indicators of compromise IOC. The use of two different DLLs for network communications points to the existence of at least two different versions of the API hashing tool.

A common way of displaying hash codes is via hexidecimal numbers, for example "Cheese for Everyone! While this format works well for displaying single codes, some files in Wabbajack may contain hundreds of thousands of hash codes.

Therefore Wabbajack chooses to use base 64 encoding instead. Most numbers used by humans like the number 42 are written in base 10 format 10 values for a single digit place.
