  2. Microsoft SmartScreen - Wikipedia

    en.wikipedia.org/wiki/Microsoft_SmartScreen

    Microsoft faced concerns surrounding the privacy, legality and effectiveness of the new system, suggesting that the automatic analysis of files (which involves sending a cryptographic hash of the file and the user's IP address to a server) could be used to build a database of users' downloads online, and that the use of the outdated SSL 2.0 ...

    en.wikipedia.org/wiki/Credential_Guard

    After compromising a system, attackers often attempt to extract any stored credentials for further lateral movement through the network. A prime target is the LSASS process, which stores NTLM and Kerberos credentials.

  4. Microsoft Office password protection - Wikipedia

    en.wikipedia.org/wiki/Microsoft_Office_password...

    Using SHA-1 as a hash function, the password is stretched into a 128-bit key 50,000 times before opening the document; as a result, the time required to crack it is vastly increased, similar to PBKDF2, scrypt or other KDFs. [citation needed] Office 2010 employed AES and a 128-bit key, but the number of SHA-1 conversions doubled to 100,000. [4]

    The protocol exists in two versions, MS-CHAPv1 (defined in RFC 2433) and MS-CHAPv2 (defined in RFC 2759).MS-CHAPv2 was introduced with pptp3-fix that was included in Windows NT 4.0 SP4 and was added to Windows 98 in the "Windows 98 Dial-Up Networking Security Upgrade Release" [1] and Windows 95 in the "Dial Up Networking 1.3 Performance & Security Update for MS Windows 95" upgrade.

  7. File verification - Wikipedia

    en.wikipedia.org/wiki/File_verification

    File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.

  9. Simple file verification - Wikipedia

    en.wikipedia.org/wiki/Simple_file_verification

    SFV verification ensures that a file has not been corrupted by comparing the file's CRC hash value to a previously calculated value. [1] Due to the nature of hash functions, hash collisions may result in false positives, but the likelihood of collisions is usually negligible with random corruption. (The number of possible checksums is limited ...
