Hooking Chrome’s SSL functions ON 26 FEBRUARY 2018 BY NYTROSECURITY The purpose of NetRipper is to capture functions that encrypt or decrypt data and send them through the network. This can be easily achieved for applications such as Firefox, where it is enough to find two DLL exported functions: PR_Read and PR_Write, but it is way more difficult for Google Chrome, where the SSL_Read and SSL_Write functions are not exported. The main problem for someone who wants to intercept such calls, is that we cannot easily find the functions inside the huge chrome.dll file. So we have to manually find them in the binary. But how can we do it? Chrome’s source code In order to achieve our goal, the best starting point might be Chrome’s source code. We can find it here: https://cs.chromium.org/ . It allows us to easily search and navigate through the source code. Articol complet: https://nytrosecurity.com/2018/02/26/hooking-chromes-ssl-functions/
