A week in security (October 30 – November 5)

Last week on our blog, we told you what to expect at the upcoming Irisscon security conference in Dublin. We gave you a quick introduction into the why and how of analyzing malware based on their API calls. And we issued a warning about some lesser-known cybercrimes. Plus we explained why emergin...

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...
