This may seem counterintuitive since most people want to simply prevent an attack and move on. Microsoft’s recommended mitigation prioritizationīased on our experience with ransomware attacks, we’ve found that prioritization should focus on these three steps: prepare, limit, and prevent. We welcome the opportunity for any additional ransomware-related work by providing clarifying guidance using whatever tools and technologies organizations have available.įigure 2: Secure backup instructions from Microsoft’s human-operated ransomware page. Microsoft already works with NIST NCCoE on several efforts, including the Zero Trust effort, which supports Presidential Executive Order (EO) 14028 on Improving the Nation’s Cybersecurity. As a result, we built guidance to make following these steps as clear and easy as possible. Microsoft has also found that many organizations struggle with the next level of the planning process. We believe all organizations should begin with simple and straightforward prioritization of efforts (three steps) and we have published this, along with why each priority is important.įigure 1: Recommended mitigation prioritization. We’ve also seen that many organizations still struggle with where to start, especially smaller operations with limited staff and experience. The ransomware operators often buy login credentials to organizations from other attack groups, rapidly turning what seems like low-priority malware infections into significant business risks. Today’s attackers have evolved far beyond this-using toolkits and sophisticated affiliate business models to enable human operators to target whole organizations, deliberately steal admin credentials, and maximize the threat of business damage to targeted organizations. We’re also seeing a widespread perception that ransomware is still constrained to basic cryptolocker style attacks, first seen in 2013, that only affect a single computer at a time (also known as the commodity model). While ransom is still the main monetization angle, attackers are also stealing sensitive data (yours and your customers’) and threatening to disclose or sell it on the dark web or internet (often while holding onto it for later extortion attempts and future attacks). One common misconception about ransomware attacks is that they only involve ransomware-”pay me to get your systems and data back”-but these attacks have actually evolved into general extortion attacks. While ransomware and extortion attacks are still evolving rapidly, we want to share a few critical lessons learned and shed some light on common misconceptions about ransomware attacks. After we wrote up our feedback for NIST, we realized it would be helpful to share this perspective more broadly to help organizations better protect themselves against the rising tide of (highly profitable) ransomware attacks. On July 14, 2021, the National Cybersecurity Center of Excellence 1 (NCCoE) at the National Institute of Standards and Technology 2 (NIST) hosted a virtual workshop 3 to seek feedback from government and industry experts on practical approaches to preventing and recovering from ransomware and other destructive cyberattacks.
