4	2	Windows Defender Ransomware Protection	Protection	GPO	Windows Defender includes a security feature called "Ransomware Protection" that allows you to enable various protections against ransomware infections. This feature is disabled by default in Windows 10. It can be activated via GPO and has the name "Controlled Folder Access".

5	3	Block Macros	Resistence	GPO	Disable macros in Office files downloaded from the Internet. This can be configured to work in two different modes: A.) Open downloaded documents in 'Protected View' B.) Open downloaded documents and block all macros	Low	High	Medium	Critical business processes that depend on macros (they exist, it's sad, but yes)	https://www.404techsupport.com/2016/04/office2016-macro-group-policy/?utm_source=dlvr.it&utm_medium=twitter	https://support.office.com/en-us/article/Enable-or-disable-macros-in-Office-files-12b036fd-d140-4e74-b45e-16fed1a7e5c6?ui=en-US&rs=en-US&ad=US
6	4	Block Windows Binary Access to Internet	Resistence	GPO	Use Windows Firwall policies to block binaries access to the so called "Remote Scope". These binaries include powershell.exe, bitsadmin.exe, certutil.exe, regsrv32.exe, mshta.exe, msbuild.exe, hh.exe, makecab.exe, ieexec.exe, extract.exe, expand.exe (see the links for details)	Medium	High	Low	PowerShell and other scripted tools that pull updates from the Internet	https://medium.com/@dimitrismargaritis/prevent-legitimate-windows-executables-to-be-used-to-gain-initial-foothold-in-your-infrastructure-39771cd6ec90
7	5	Filter Attachments Level 1	Resistence	Mail Gateway	Filter the following attachments on your mail gateway: .386, .ace, .acm, .acv, .ade, .adp, .adt, .ani, .app, .arc, .arj, .asd, .asp, .avb, .ax, .bas, .bat, .boo, .btm, .cab, .cbt, .cdr, .cer, .chm, .cla, .cmd, .cnv, .com, .cpl, .crt, .csc, .csh, .css, .dll, .dmg, .drv, .dvb, .email, .exe, .fon, .fxp, .gms, .gvb, .hlp, .ht, .hta, .htlp, .htt, .inf, .ini, .ins, .iso, .isp, .its, .jar, .job, .js, .jse, .ksh, .lib, .lnk, .maf, .mam, .maq, .mar, .mat, .mau, .mav, .maw, .mch, .mda, .mde, .mdt, .mdw, .mdz, .mht, .mhtm, .mhtml, .mpd, .mpt, .msc, .msi, .mso (except oledata.mso), .msp, .mst, .nws, .obd, .obj, .obt, .obz, .ocx, .ops, .ovl, .ovr, .pcd, .pci, .perl, .pgm, .pif, .pl, .pot, .prf, .prg, .ps1, .pub, .pwz, .qpw, .reg, .sbf, .scf, .scr, .sct, .sfx, .sfx, .sh, .shb, .shs, .shtml, .shw, .smm, .svg, .sys, .td0, .tlb, .tmp, .torrent, .tsk, .tsp, .tt6, .url, .vb, .vbe, .vbs, .vbx, .vom, .vsmacro, .vss, .vst, .vsw, .vwp, .vxd, .vxe, .wbk, .wbt, .wIz, .wk, .wml, .wms, .wpc, .wpd, .ws, .wsc, .wsf, .wsh	Low	Medium	Low	Unknown if one of the extensions is used by business applications.

8	6	Filter Attachments Level 2	Resistence	Mail Gateway	Filter the following attachments on your mail gateway: (Filter expression of Level 1 plus) .doc, .docx, .xls, .xlsx, .rtf, .docm, .xlsm, .pptm, .bin, .one	Medium	High	High	Office Communication with old versions of Microsoft Office files (.doc, .xls)
9	7	Use Web Proxies	Resistence	Best Practice	Most malware isn't proxy-aware and tries to connect directly to their C2 or web host that holds the next stage.	Low	High	Medium	It's a change in your architecture that could lead to all kinds of issues.
10	8	Block Executable Downloads / Splash Screens	Resistence	Best Practice	When using a web proxy, block executable downloads. Alternatively just block executable downloads from all domains classified as "unknown" or "unclassified". A more moderate approach would be to show a splash page for every new (unknown) domain.	Low	High	Medium	This could be an issue if you don't have a sound software management and every workstations pulls updates directly from the Internet instead of a local software distribution server
11	9	Enforce UAC Prompt	Resistence	GPO	Enforce administrative users to confirm an action that requires elevated rights	Low	Medium	Low	Administrator's resentment	https://technet.microsoft.com/en-us/library/dd835564(WS.10).aspx

13	11	Restrict Workstation Communication	Resistence	Best Practice	Activate the Windows Firewall to restrict workstation to workstation communication. This reduces the impact of a single infected machine as it cannot spread from workstation to workstation using the extracted credentials.	Medium	Low	Low		https://medium.com/@cryps1s/endpoint-isolation-with-the-windows-firewall-462a795f4cfb
14	12	Sandboxing Email Input	Protection	Advanced Malware Protection	Using sandbox that opens email attachments and removes attachments based on behavior analysis	Medium	High	-

16	14	Change Default "Open With" to Notepad	Resistence	GPO	Force extensions primarily used for infections to open up in Notepad rather than Windows Script Host or Internet Explorer	Low	Medium	Medium	Some extensions will have legitimate uses, e.g., .vbs for logon scripts.	https://bluesoul.me/2016/05/12/use-gpo-to-change-the-default-behavior-of-potentially-malicious-file-extensions/
17	15	Restrict program execution	Resistence	GPO	Block program executions (AppLocker)	Medium	Medium	Medium	Configure & test extensively, white-list or black-list approach?	https://technet.microsoft.com/en-us/library/dd759117%28v=ws.11%29.aspx	http://social.technet.microsoft.com/wiki/contents/articles/5211.how-to-configure-applocker-group-policy-to-prevent-software-from-running.aspx
18	16	Sysmon	Detection	3rd Party Tools	Detect Ransomware in an early stage with new Sysmon 5 File/Registry monitoring	Medium	Low	Low		https://twitter.com/JohnLaTwC/status/799792296883388416
19	17	VSSAdmin Rename	Resistence	Best Practice	Rename vssadmin to avoid Ransomware deleting the volume shadow copies on a drive	Medium	Medium	Medium	1. Unknown what happens after Microsoft patches that involve vssadmin.exe, 2. backup solutions that make use or expect vssadmin.exe	https://www.bleepingcomputer.com/news/security/why-everyone-should-disable-vssadmin-exe-now/
20	18	Disable WSH	Resistence	GPO	Disable Windows Script Host	Low	Medium	Medium	Could affect administrative VBS scripts on workstations	http://www.windowsnetworking.com/kbase/WindowsTips/WindowsXP/AdminTips/Customization/DisableWindowsScriptingHostWSH.html
21	19	Folder Redirection	Resilience	Best Practice	Redirect e.g. the "Documents" folder to a shared folder on a file server to facilitate backups	Medium	Low	Medium
22	20	Remove Backup Server from Domain	Resilience	Best Practice	A ransomware that propagates with domain user rights may infect and encrypt the backup server as well. Prevent this by configuring it as stand-alone server	Medium	High	Medium	Makes administration more difficult as admins cannot use their Active Directory user account on these systems
23	21	MFA	Resistence	Best Practice	Only provide remote access via Multi-Factor-Authentication (MFA) to avoid brute force and password spraying attacks on Internet facing services like RDP	Low	Medium	Low	Every second factor works, it doesn't have to be an expensive hardware token. TOTP offers good value for money. Even software certifcates are better than just username & password.	https://www.microsoft.com/security/blog/2020/04/28/ransomware-groups-continue-to-target-healthcare-critical-services-heres-how-to-reduce-risk/	https://www.nytimes.com/wirecutter/reviews/best-two-factor-authentication-app/	https://www.privacyidea.org/	https://github.com/multiOTP/multiOTPCredentialProvider/blob/master/README.md	https://guacamole.apache.org/doc/gug/totp-auth.html#guac-totp-config

1	LIST DOESN'T GET UPDATED ANYMORE
2	NOTE: We initiated this list back in 2016 when adding a new ransomware occasionally was manageable as a side project. However, times have shifted, and ransomware has grown into a relentless pandemic. We're entrusting AV vendors with the task of maintaining their lists, and will discontinue this project. For historical research, this tab will remain. It was updated regularly from 2016 to 2018 and had sporadic updates in 2019.
