How to solve the Malwarebytes CrackMe: a step-by-step tutorial

The topic of this post is a Malwarebytes CrackMe—an exercise in malware analysis that I recently created. First, the challenge was created to serve internal purposes, but then it was released to the community on Twitter and triggered a lot of positive response. Thanks to all of you who sent in yo...

Analyzing malware by API calls

Over the last quarter, we've seen an increase in malware using packers, crypters, and protectors—all methods used to obfuscate malicious code from systems or programs attempting to identify it. These packers make it very hard, or next to impossible to perform static analysis. The growing number o...

A Modern Hypervisor as a Basis for a Sandbox

In the field of information security, sandboxes are used to isolate an insecure external environment from a secure internal environment or vice versa, to protect against the exploitation of vulnerabilities, and to analyze malicious code. At Kaspersky Lab, we have several sandboxes, including an...
