[QUOTE="NoVirusThanks, post: 715825, member: 68429"] Here is a new v1.4 (pre-release) (test38): [URL]http://downloads.novirusthanks.org/files/osarmor_setup_1.4_test38.exe[/URL] *** Please do not share the download link, we will delete it when we'll release the official v1.4 *** So far this is what's new compared to the previous pre-release: + Block execution of cacls\icacls\xcacls.exe + Block execution of takeown.exe + By default "Block execution of taskkill.exe" is disabled + Improved detection of suspicious processes + Improved detection of suspicious command-lines + Improved detection of Bitcoin miner command-lines + Improved detection of PowerShell malformed commands + Improved OSArmor self defense (basic) + Self-protection (basic) is enabled by default and can't be disabled + Prevent wevtutil.exe from cleaning Windows Eventlog + Prevent Windows Firewall from being disabled via command-line + Fixed some false positives To install it, first uninstall the previous build, then reboot (not really needed but may help), and install the new build. [USER=58943]@ForgottenSeer 58943[/USER] FPs should be fixed, thanks for reporting them. [USER=37647]@shmu26[/USER] Can you post the log of the blocked event? [USER=70500]@Carphedon[/USER] I have fixed the FP. I'm sure it matched some internal whitelist rules. [USER=32547]@AtlBo[/USER] Added the option "Prevent Windows Firewall from being disabled via command-line". It covers sc.exe, wmic.exe, net.exe, netsh.exe, etc. Example: [code] Date/Time: 05/03/2018 15:55:24 Process: [2680]C:\Windows\System32\netsh.exe Parent: [4272]C:\Windows\System32\cmd.exe Rule: PreventWindowsFirewallFromBeingDisabledViaCmdline Rule Name: Prevent Windows Firewall from being disabled via command-line Command Line: netsh advfirewall set allprofiles state off Signer: Parent Signer: Date/Time: 05/03/2018 15:58:24 Process: [3148]C:\Windows\System32\sc.exe Parent: [1964]C:\Windows\System32\cmd.exe Rule: PreventWindowsFirewallFromBeingDisabledViaCmdline Rule Name: Prevent Windows Firewall from being disabled via command-line Command Line: sc stop MpsSvc Signer: Parent Signer: [/code] [/QUOTE]
