CVE-2020-24586PUBLISHED: 2021-05-11
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted us...
CVE-2020-24587PUBLISHED: 2021-05-11
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and...

Encrypt your data. CryptoWall can't encrypt files that are already encrypted by the end user.
The data can be decrypted on access which would lock the files currently opened. When the file is closed it is
automatically re-encrypted in realtime. As an extra layer of security it is also possible to encrypt volume shadow
copies of the files as the behavior of CryptoWall will automatically sdelete (Secure Delete) all shadow copy data
on the infected machine. I am no way suggesting not to backup your data. However, a proper retention policy
should also be correctly set to seven or more days. If a backup whether it be to a local, network drive, or cloud
based is not encrypted there remains the risk of the files being encrypted by the ransomware and changes of
modified files by CryptoWall propagating and overwriting the original backup of end user data. Also, CrytoWall
only affects files by extention (ie .docx, .qbw, .xlsx) If a file extention is modified to something completely
obscure in no relation with any application they will remain unaffected by this ransomware.
