1. Introduction When everything else fails — antivirus, patching, the human factor — one answer remains for the worst-case scenario: the backup. But a copy without immutability is a false sense of security when the attacker knows where your data lives, because 94% of ransomware attacks attempt to compromise backups and 57% succeed. Immutable backups are the difference between a restoration in days and a negotiation with the extortionist or, in the worst case, the end of the business. In this article you will see the 3-2-1-1-0 rule explained piece by piece, what real immutability means compared with a revocable …

This methodology for installing various types of malware has been observed in a large number of forensic analyses of ransomware attacks, and it’s not surprising considering the ease and nature of exploitation, as we will see throughout this article. To follow along, you will need to have at least basic knowledge of brute force tools and exploit launching. We will be using Kali Linux as the attacking machine. 2. …
