FAKE GOOGLE CHROME UPDATE 2018 CODE

This results in a few things: 1) if an address is leaked successfully, it means the exploit is working correctly 2) a leaked address is used to know where the heap/stack is located and that defeats the address space layout randomization (ASLR) technique 3) a few other useful pointers for further exploitation could be located by searching near this address.ДЄfter that it tries to create a bunch of large objects using a recursive function. The exploit first tries to trigger UaF to perform an information leak about important 64-bit addresses (as a pointer).

It gives an attacker an a Use-After-Free (UaF) condition that is very dangerous because it can lead to code execution scenarios, which is exactly what happens in our case. The exploit used a race condition bug between two threads due to missing proper synchronization between them. The analysis we have provided here is deliberately brief due to vulnerability disclosure principles. There are a few big arrays with numbers that represent a shellcode block and an embedded PE image.As this bug has still not been fixed, we are not including details about the specific vulnerable component here. The majority of the code uses several classes related to a certain vulnerable component of the browser.This usually means that they were used for debugging code and were then left behind when the code was moved to production. There are many functions and variables that are not used in the actual code.

Snippet of code to work with 64-bit numbers A malicious JavaScript code was inserted in the main page, which in turn, loads a profiling script from a remote site. The attack leverages a waterhole-style injection on a Korean-language news portal. For more information, contact: Technical details More details about CVE-2019-13720 and recent DarkHotel false flag attacks are available to customers of Kaspersky Intelligence Reporting. The profile of the targeted website is more in line with earlier DarkHotel attacks that have recently deployed similar false flag attacks. There are certain very weak code similarities with Lazarus attacks, although these could very well be a false flag. So far, we have been unable to establish a definitive link with any known threat actors. We are calling these attacks Operation WizardOpium. Kaspersky endpoint products detect the exploit with the help of the exploit prevention component. 87 for Windows, Mac, and Linux and we recommend all Chrome users to update to this latest version as soon as possible! You can read GoogleвЂ™s bulletin by clicking here. After reviewing of the PoC we provided, Google confirmed there was a zero-day vulnerability and assigned it CVE-2019-13720. We promptly reported this to the Google Chrome security team. Recently, it caught a new unknown exploit for GoogleвЂ™s Chrome browser. Kaspersky Exploit Prevention is a component part of Kaspersky products that has successfully detected a number of zero-day attacks in the past.
