# Malware Analysis [#4] —Eternity Project — Eternity Stealer

• Eternity Stealer — $260 annual subscription. • Eternity Miner —$90 annual subscription.
• Eternity Worm — $390. • Eternity Ransomware —$490.
• Eternity Clipper — \$110.
• Eternity DDoS Bot — (Still in development).

## Analyzing Obfuscation Methods:

• Takes two string arguments.
• Remove the first and last character from second string argument then decode from base64 and the result will be used as a secret key in the AES decryption.
• Decode the first string argument from base64 and use it as IV in the AES decryption.
• After decryption it returns UTF8 string.
• Takes a string and long arguments.
• Convert the string argument to char array.
• Use a for loop to convert both arguments to and int32 and then check if the two argument Combined are between 0 and 256 and if it is it will sub first argument from the second argument and convert it to char, then convert uppercase char to lowercase and lowercase to uppercase.
• Reverse the char array and return it as a string.

## Main Method:

• UnhandledException (Occurs when an exception is not caught).
• ProcessExit(Occurs when the default application domain’s parent process exits).
• chcp 65001 .
• ping 127.0.0.1 .

• CreateNoWindow.
• UseShellExecute
• Expect100Continue: Gets or sets a Boolean value that determines whether 100-Continue behavior is used. The HTTP 100 Continue informational status response code indicates that everything is OK and that the client should continue with the request or ignore it if it is already finished. The malware here gave it “1“ by getting the size of float which is 4 bytes then subs 3 from it, the result is 1 which means true.
• DefaultConnectionLimit: Gets or sets the maximum number of concurrent connections allowed by a “ServicePoint” object. The value of this property is 9999, also by getting the size of float and add 9995 to it.
• SecurityProtocol: Gets or sets the security protocol used by the “ServicePoint” objects managed by the “ServicePointManager” object. The security type protocol is “Tls12” which has the value 3072 as mentioned in MS documents, the same process again get the size of float then add 3068.
