Update (9 Jan 2020) The government has announced the decision to make all publications in the Gazette freely available to the public. Kudos to the government for doing so! As such, there is no point in continuing to archive them. I have turned off the search feature. However, this page will ...

Let us take a look at the Cybersecurity Act 2018 and see how it affects professionals in the industry. I believe it is a good first step, however more can be done in terms of enforcement as well as to ensure better wording of the law. 1 2 3 4 5 6 7 8 9 10 11 12S2 Interpretation “cybersecurity” ...

Since shellcode is usually very small in size, I have used RSA asymmetric encryption to encrypt the shellcode. Most of the code is boilerplate code so there is not much to talk about. Encryptor. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 ...

I have taken shellcode #603 and #859 from shell-storm and created polymorphic version that passed clamav scan. The original version of both shellcodes were detected by clamav scan due to the presence of the /bin/sh string. Breaking up the string caused the modified versions of both shellcodes ...

I would be analysing chunks of the linux/x64/meterpreter/bind_tcp and the linux/x64/shell_bind_tcp and see how they differ. Although both are TCP bind shellcode, the primary difference among them is that the meterpreter shellcode is a staged payload while the other is a stageless payload. As ...

I decided to do something special for the custom encoder shellcode. I used the Intel SSE4.2 CRC32C function to encode the shellcode. CRC32 is a hash function, not an encoding function, so in order to make it an encoder, I had to compute the preimage for each possible byte of the final shellcode ...

As usual, I will only be touching on interesting or unique points in the shellcode. Line 25/26: To avoid having the egg in memory, I moved 0x5090508f into a register and incremented it to get 0x50905090 Line 27: repne scasd searches the next 4 bytes and increments the address searched ...
