hello dj stevens senior handler at the internet storm center xavier has a great diary entry about houdini and the remote access tool a very old remote access tool any font is inside a javascript dropper and it is embedded as base64 but it is not standard base64 and so xavier looks through the script to find the decoding function and is able to decode the base64 the obfuscated base64 properly iamp;#39;m now going to do that too but iamp;#39;m not going to use the decoder iamp;#39;m going to perform statistical analysis of the encoded payload to try to recover it so i do have the sample here and here comes the payload which looks like base 64. now as xavier said thereamp;#39;s very simple and great trick to find uh special encodings well payloads uh in inside scripts and that is to sort uh your script the lines of the script by the length so that the longest lines are at the end for example and that is something you can do with my strings tools strings typically works on bina

Does base64 always end in ==?

Base64 strings tend to end in one or two equal signs, but not always! These strings are not exact representations of the binary data in ASCII, because padding is applied to ensure the string length is a multiple of 4 characters. Each equal sign represents two bits of zero-padding.

What code has == at the end?

A Base64 string will end with == if and only if the number of bytes it encodes, mod 3, equals 1. Do you see the pattern? It happens that 16-byte (128-bit) encryption keys are very commonly encoded in Base64, and since 16 mod 3 = 1, their encoding will end with == . But your string, decoded, is 61 bytes (488 bits) long.

What is the radix 64 encoding?

What is Radix 64 Encoding? Radix 64 encoding allows binary data stored in octets (i.e. bytes) to be expressed as printable characters.

What symbols are allowed in Base64?

Base64 is a scheme for converting binary data to printable ASCII characters, namely the upper- and lower-case Roman alphabet characters (AZ, az), the numerals (09), and the + and / symbols, with the = symbol as a special suffix code. The datas original length must be a multiple of eight bits.

What characters does base64 not use?

Base64 only contains AZ , az , 09 , + , / and = . So the list of characters not to be used is: all possible characters minus the ones mentioned above. For special purposes . and are possible, too.

How do I exclude a new line in base64?

you can add the -w 0 option to the base64 command to change the behavior so that it no longer adds new lines. So please use echo -n to remove the line break before redirecting to base64 ; and use base64 -w 0 to prevent base64 itself to add line break into the output.

What does equals mean in base 64?

When decoding Base64 text, four characters are typically converted back to three bytes. The only exceptions are when padding characters exist. A single = indicates that the four characters will decode to only two bytes, while == indicates that the four characters will decode to only a single byte. For example: Encoded.

Which encoding ends with ==?

The = sign is used to indicate padding if the input string length is not a multiple of 3 bytes. If we have four bytes for the input, then the base64 encoding ends with two equal signs, just to indicate that it had to add two characters of padding.
