[QUOTE="Andy Ful, post: 945555, member: 32260"] The video as an anti-ransomware protection test has many flaws noted already in this thread. Anyway, it is a good basic presentation of the AV capabilities for educational purposes. it can also show that the protection of Defender free on default settings with additionally enabled Controlled Folder Access can be compromised by some sophisticated ransomware. It seems that at least one sample (MedusaLocker) partially defeated Defender. Although the files in protected folders were not encrypted, some other files were successfully encrypted and the ransomware made the system unbootable for some reason (not uncovered in the video). For more comprehensive protection the Defender settings require enabling ASR rules. The MedusaLocker samples were used in the targeted attacks especially in the healthcare industry.
