I have a few goals for this blog: Hone my skills by analyzing malware on a regular, more frequent basis. Learn new analysis tools and techniques Contribute to malware OSINT via social media and other sharing methods Eventually, progress to full blown reverse engineering of malware I'm hoping to keep things useful and simple. My biggest influence is  https://www.malware-traffic-analysis.net/ . Brad provides useful malicious IOCs and traffic analysis on a near-daily basis. Big fan. Some techniques you will see here may be considered amateur. I'm open to feedback. Here we go. Love, casual_malware
