SINCON 2021 Conference — Ransomware Exploded — by Chester Wisniewski

SINCON 2021 Conference — Fix-It Talk

Day 2 (06 Nov 2021) 10.00am—10.45am @ Main Room

Ransomware Exploded: Modern Defences Against a Technological Plague


Criminals are able to leverage increasingly smaller defensive mistakes into multi-million dollar extortion opportunities. This talk will explore the techniques, tools and procedures employed by the most prominent ransomware groups. I will also recommend what security policy changes can lower the risk of compromise and the types of skills and tools needed to detect and respond if those policies fail. As criminals continue to abuse legitimate system administration tools in conjunction with obfuscated malicious scripts security teams need "big picture" visibility more than ever to find and exterminate malicious intrusions. Threats are evolving quickly, has your security team kept up with the latest tactics?
