Hello,
<div><br class="ContentPasted0">
</div>
<div class="ContentPasted0">I hope everyone is doing well!</div>
<div><br class="ContentPasted0">

<div class="ContentPasted0">Below is the entry for today.</div>

<div class="ContentPasted0">10/14/2022 - Diary entry #614:</div>
<div><br class="ContentPasted0">

<blockquote style="margin-top:0;margin-bottom:0">
<div class="ContentPasted0 ContentPasted1">A new ransomware named Prestige was recently discovered in attacks detected within an hour of each other, impacting organizations in Ukraine and Poland. First deployed on October 11, the threat’s activity overlaps
with previous victims of the FoxBlade malware, also known as HermeticWiper, a very dangerous kind of malware used for erasing data or making devices unusable (covered in our Daily Diary #462).
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">Tracked as DEV-0960, the group responsible for deploying the ransomware was observed using RemoteExec and Impacket WMIexec, both are open-source remote code execution tools. To escalate privileges, move laterally, and deploy the
ransomware, they used winPEAS, an open-source collection of scripts, and tools to back up the Active Directory database and dump credentials from the LSASS process.</div>
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">Before encrypting files, the ransomware payload stops the MSSQL Windows service to avoid interruption during the encryption process and then starts encrypting all files using AES (from the CryptoPP C++ library). After encrypting
each file, the extension ”.enc” is then appended to the original file name and a ransom note is dropped on each folder.</div>
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">Additionally, it deletes the Windows backup catalog and the shadow copies and registers a custom file extension handler for files with the “.enc“ extension. When the victim doubles-click an encrypted file, it opens the ransom note
on the notepad. To contact the criminals and get the data back, the ransom note provides the email address “Prestige.ranusomeware@Proton.me“ [sic].</div>
<div><br class="ContentPasted1">
</div>
After being attacked by the HermeticWiper malware, Ukrainian organizations are now also impacted by this new ransomware. It’s still unclear if this ransomware strain is strictly politically motivated but either way, organizations around the globe should prepare
and defend against this new adversary.<br>
