Of course YourUserName should be your user name, and you should use the correct path to the file you want to check.
SHA256 CHECKSUM WINDOWS 10 DOWNLOAD
In general I would assume that someone with server access would change both (the ftp and http download files) to the malicious one and may also change the given checksums. First open the Windows Powershell (click Start then type Powershell then click it), then use the command below checking the file wire.exe as an example. I have expirienced that a file downloaded over ftp doesn't get this flag and because of this can be executed without warning. The file gets flaged, so Windows always knows to ask first.
You can give it a try by verifying the programs own checksum. The utility will automatically run the file through the MD5, SHA-1, and SHA-256 cryptographic functions and output them for you. Historically it was widely used as a cryptographic hash function. Follow the steps below to verify that the SHA256 checksum of the downloaded file matches that of the SHA256 checksum listed at the Hak5 official download. The SmartScreen thing is AFAIK allways showing when executing files downloaded from the web, except for some defined 'good' pages. Download and run Raymond’s MD5 & SHA Checksum Utility (Download) Click File, browse to your file you want to verify, and select it. MD5 can be used as a checksum to verify data integrity against unintentional corruption. Originally designed for Linux, but also available for Windows and Apple Mac OSX. (A little offtopic: may you explain why you tried to execute potentially harmfull files again after a reboot?) QuickHash GUI is an open-source graphical interface data hashing tool for Linux, Windows, and Apple Mac OSX. It may be that the change from this tempfile to the normal file was not finished (perhaps because of a writelock), and so the checksums where different.Īs you rebooted your system, this process may have come to an end, so the checksums got right after.
What browser are you using? I know that some browsers don't safe the file immediately but create a temp file while downloading. Without further details of it nobody can tell you exactly what happened. IMPORTANT: Everything following is only part of my assumptions about this incident.
