Helpful vaccine (not killswitch!)

Looks like if you block C:\Windows\perfc.dat from writing/executing - stops #Petya. Is used for rundll32 import.

Local kill switch - create file "C:\Windows\perfc"
It kills WMI vector. Still need to patch MS17-010 for full protection.

Thanks to the https://twitter.com/OxFemale for the initial malware body.

Source code:

  • Archive password: virus

Thanks to the @Sn0wFX_:

Initial vector:

Ransomware includes:

  • Modified EternalBlue exploit
  • A vulnerability in a third-party Ukrainian software product
  • A second SMB network exploit

Origin (NO PROOF):

Petya was known to be RaaS (Ransomware-as-a-Service), selling on Tor hidden services. Looks like WannaCry copycat. Attribution will be hard. https://twitter.com/x0rz/status/879733138792099842

AvP Bypass

Confirmed AvP bypasing trick is being used by Petya ransomware to evade 6 popular anti-virus signatures (script) https://twitter.com/hackerfantastic/status/880012620698451968

https://github.com/HackerFantastic/Public/blob/master/tools/bypassavp.sh

Vulnerabilities/Vectors/Actions:

MS17-010

PSEXEC: %PROGRAMDATA%\dllhost.dat is dropped and is legit PSEXEC bin

Remote WMI, “process call create \"C:\\Windows\\System32\\rundll32.exe \\\"C:\\Windows\\perfc.dat\\\" #1”

Log clean, «wevtutil cl Setup & wevtutil cl System & wevtutil cl Security & wevtutil cl Application & fsutil usn deletejournal /D %c:»

Creates a scheduled task that reboots 1 hour after infection. If task removed before the hour, does not reschedule and can buy time

Petya also attempts to kill Exchange & MySQL if they are running.  If you host either of these services and notice them die, this is including in it's infection process (svchost.exe) // by Mike "Bones" Flowers:

Exec: C:\\windows\\system32\\cmd.exe
Params: /c taskkill.exe /f /im Microsoft.Exchange.*
Exec: C:\\windows\\system32\\cmd.exe
Params: /c taskkill.exe /f /im MSExchange*
Exec: C:\\windows\\system32\\cmd.exe
Params: /c taskkill.exe /f /im sqlserver.exe
Exec: C:\\windows\\system32\\cmd.exe
Params: /c taskkill.exe /f /im sqlwriter.exe
Exec: C:\\windows\\system32\\cmd.exe
Params: /c taskkill.exe /f /im mysqld.exe
The new ransomware can also spread using an exploit for the Server Message Block (SMB) vulnerability CVE-2017-0144 (also known as EternalBlue), which was fixed in security update MS17-010 and was also exploited by WannaCrypt to spread to out-of-date machines. In addition, this ransomware also uses a second exploit for CVE-2017-0145 (also known as EternalRomance, and fixed by the same bulletin)

Machines that are patched against these exploits (with security update MS17-010 https://technet.microsoft.com/en-us/library/security/ms17-010.aspx) or have disabled SMBv1 (https://support.microsoft.com/kb/2696547) are not affected by this particular spreading mechanism

Test local account behavior [NOT TESTED]:

Don't know if you have also noticed, but it only encrypted the MFT records for my test user account profile folders, the default Windows accounts Administrator, default user etc were all untouched, my test account was local so I don't know what behaviour would be expected for domain account profile folders.

100% on the sample used by me and on a standalone computer, user files were encrypted prior to reboot and the malware was not able to escalate privileges to deploy the MFT encryption payload, no instructions were deposited about recovering these files

If you can boot to a Windows ISO prior to Frist reboot you can use bootrec tool to prevent MBR overwriting as per https://neosmart.net/wiki/fix-mbr

Tested this malware in closed lab environment. Executed malware in domain joined Windows 7 machine with local administrator. This same local admin account was in other domain machines except one that I configured differently on purpose. Spreads very quickly in network using psexec and wmic. I also had one domain controller and one workgroup Windows 7 machine with different local admin account than other machines. I wanted to see that will it spread to them too using Eternalblue but malware didn't infect them at all for some reason. Those machines didn't have patch for EternalBlue.

Also noted that it didn't create a perfc file in C:\Windows. It created a empty file named petya in C:\Windows. Petya was the name of a file where I originally executed the malware.

Hi! I'm a user of this Medoc software. This April, my Windows Defender found a Trojan:Win32/Rundas.A in Medoc's update package 10.01.168-10.01.169. I have deleted the file and Defender has deleted Trojan. I attach the log of this process, if it can help anyone. I wasn't affected by the attack on 27th June (might be because didn't use Medoc on that day).

The 3rd known attack vector is a local news site in Bahmut (Donetsk region):

Please, add link Analysis of TeleBots’ cunning backdoor (https://www.welivesecurity.com/2017/07/04/analysis-of-telebots-cunning-backdoor/)
and information from post

The backdoored module has the filename ZvitPublishedObjects.dll. This was written using the .NET Framework. It is a 5MB file and contains a lot of legitimate code that can be called by other components, including the main M.E.Doc executable ezvit.exe.

We examined all M.E.Doc updates that were released during 2017, and found that there are at least three updates that contained the backdoored module:
01.175-10.01.176, released on 14th of April 2017
01.180-10.01.181, released on 15th of May 2017
01.188-10.01.189, released on 22nd of June 2017

and

Warning! We recommend changing passwords for proxies, and for email accounts for all users of M.E.Doc software.

Please, change information

The new ransomware can also spread using an exploit for the Server Message Block (SMB) vulnerability CVE-2017-0144 (also known as EternalBlue), which was fixed in security update MS17-010 and was also exploited by WannaCrypt to spread to out-of-date machines. In addition, this ransomware also uses a second exploit for CVE-2017-0145 (also known as EternalRomance, and fixed by the same bulletin)

Machines that are patched against these exploits (with security update MS17-010 https://technet.microsoft.com/en-us/library/security/ms17-010.aspx) or have disabled SMBv1 (https://support.microsoft.com/kb/2696547) are not affected by this particular spreading mechanism
