This code is highly obfuscated, and it appears to include numerous techniques to obscure its functionality. However, I can infer its general behavior:
-
Purpose and Commons Signs:
- The code seems to involve some kind of execution or response to network commands, potentially including executing functions or Cmdlets related to "traceroute" or "command execution."
- It leverages PowerShell features (
[System.Text.Encoding]
,Base64String
,Format
strings, etc.) to obfuscate its functionality. - Various functions and command calls (like
Get-Command
) are dynamically constructed, often hiding their real names in Base64-encoded strings, XOR operations, and similar encoding schemes.
-
Base64-Decoding:
- Several commands or strings are Base64-encoded (e.g.,
R2V0LQ==
, which decodes to "Get-"), suggesting the intent to assemble commands dynamically at runtime.
- Several commands or strings are Base64-encoded (e.g.,
-
Command Construction:
- Obfuscated strings, concatenated characters, and arithmetic operations (like XOR) are used to reconstruct known PowerShell commands such as
Remove-Command
,Connect
,Get-Command
, etc.
- Obfuscated strings, concatenated characters, and arithmetic operations (like XOR) are used to reconstruct known PowerShell commands such as
-
Traceroute Activity:
- The code references "Traceroute" operations (
$VJIcs
,$zSm7H
,$E1JmCKx
), indicating that it attempts to perform network diagnostics, likely using theTraceroute
command. It processes the results into a dictionary formatting (e.g.,@{hOP; aDdrEss}
).
- The code references "Traceroute" operations (
-
Try-Catch Block:
- If an error occurs (e.g., Traceroute fails), the
catch
section of the code engages fallback behaviors. These also involve constructing commands at runtime to handle the error.
- If an error occurs (e.g., Traceroute fails), the
-
Fallback Logic:
- The fallback logic appears to log or display error information, detailing the failure of the traceroute alongside the specific target (
$zSm7H
).
- The fallback logic appears to log or display error information, detailing the failure of the traceroute alongside the specific target (
-
Obfuscation Indicators:
- Patterns like encoding, dynamic character building, and XOR manipulations (
bxor
) are classic obfuscation techniques used to evade detection for malicious scripts.
- Patterns like encoding, dynamic character building, and XOR manipulations (
Likely Intent:
The script's obfuscation and reliance on dynamically constructed commands strongly suggest it could be a malicious script, possibly used for:
- Performing network diagnostics like traceroute or tracking network targets.
- Collecting information or logging errors related to connectivity.
- Possibly executing PowerShell commands remotely.
Note: Scripts like this are often indicative of malware or post-exploitation tools, as they go to great lengths to hide what they do. If encountered in a real-world environment, you should investigate the context in which the script is being executed, verify the source, and act accordingly. Avoid executing this script in a trusted environment unless you fully understand its intent and implications.
