Bad news from Google. Government hackers in several countries have gained access to Chrome and Android vulnerabilities
Google said hackers from Greece, Serbia, Egypt, Armenia, Spain, Indonesia, Madagascar and Côte d’Ivoire have gained access to four Chrome vulnerabilities and one — Android. According to the company, Cytrox from Northern Macedonia is suspected of the data leak. She managed to develop the malicious program Predator, through which hackers from several countries gained access to the so-called «zero-day vulnerabilities». This term means software security vulnerabilities that the developer is unaware of. Google has been tracking and fixing these vulnerabilities since 2014, tracking and correcting them where possible. Among the vulnerabilities provided to hackers, Cytrox provided access to the fixed ones, which means that users did not update the software. Google Threat Analysis Group actively tracks more than 30 vendors with varying levels of complexity and publicity who sell exploits or surveillance capabilities to state-supported individuals.TAG experts write that the recently merged vulnerabilities of the system were developed by private companies .
Cybercriminals use an executable Eset file to hide the activity of the ArguePatch malware
Eset reports the discovery of an improved version of the malware downloader previously used by Sandworm during the Industroyer2 threat attack on Ukraine’s energy sector. The updated bootloader is named after CERT-UA — ArguePatch. This malware is now used to run CaddyWiper with data destruction functionality, which was used to attack Ukrainian organizations. The new version of the bootloader is a patched version of the legitimate Hex-RaysSA IDA Pro software component, namely the remote IDA debug server (win32_remote.exe). The version adds code to decrypt and run CaddyWiper from an external file. To hide ArguePatch activity, Sandworm has chosen the official Eset executable. It was stripped of its digital signature and the code was rewritten. The added code is quite similar in the previous and new versions of the bootloader, but now it contains a feature to run the next stage of the attack at a certain time. In this way, attackers replace the need to configure a scheduled Windows task to run code. This is probably a way to avoid detection using known TTPs .
