Title: Transparent Tribe adds new tools to its arsenal as it targets Indian colleges
Description: Cisco Talos has been tracking a new malicious campaign operated by the Transparent Tribe APT group. This campaign involves the targeting of educational institutions and students in the Indian subcontinent, a deviation from the adversary's typical focus on government entities. The attacks result in the deployment of CrimsonRAT, Transparent Tribe's malware of choice for establishing long-term access into victim networks. We assess with high confidence that a Pakistani web hosting services provider "Zain Hosting" was used for deploying and operating components of Transparent Tribe's infrastructure. This is likely one of many third parties Transparent Tribe employs to prepare, stage and/or deploy components of their operation. Transparent Tribe primarily uses three Windows-based malware families to carry out espionage activities against their targets, including CrimsonRAT and ObliqueRAT.

Title: Google fixes several vulnerabilities in Chrome, including one actively exploited in the wild
Description: Google released a series of patches for its Chrome web browser, including fixes for a high-severity heap buffer overflow vulnerability (CVE-2022-2294) in WebRTC. An attacker could exploit this vulnerability to carry out a range of malicious actions, including crashing the targeted device, causing a denial of service or executing remote code. Google stated in its release that CVE-2022-2294 is actively being exploited in the wild and is withholding additional information until users can patch for the issue. Additionally, Cisco Talos discovered a vulnerability in Chrome’s WebGPU standard that causes a use-after-free condition. The WebRTC vulnerability is the fourth zero-day vulnerability in Chrome to appear in the wild this year.
