Combing through the fuzz: Using fuzzy hashing and deep learning to counter malware detection evasion techniques

Today’s cybersecurity threats continue to find ways to fly and stay under the radar. Cybercriminals use polymorphic malware because a slight change in the binary code or script could allow the said threats to avoid detection by traditional antivirus software. Threat actors customize their wares...

Fast, Effective N-grams Extraction and Analysis with SQL

Features extraction is expensive, especially when dealing with big data. That’s why it’s great when you have the ability to preprocess close to the database - the data stays in the DB and doesn’t have to move out, unless necessary. One common approach for text data representation is N-grams...
