Attackers target Ukraine using GoMet backdoor

Executive summary Since the Russian invasion of Ukraine began, Ukrainians have been under a nearly constant barrage of cyber attacks. Working jointly with Ukrainian organizations, Cisco Talos has discovered a fairly uncommon piece of malware targeting Ukraine — this time aimed at a large software development company whose software is used in various state organizations within Ukraine. We believe that this campaign is likely sourced by Russian state-sponsored actors or those acting in their interests. As this firm is involved in software development, we cannot ignore the possibility that the perpetrating threat actor's intent was to gain access to source a supply chain-style attack, though at this time we do not have any evidence that they were successful. Cisco Talos confirmed that the malware is a slightly modified version of the open-source backdoor named "GoMet." The malware was first observed on March 28, 2022. GoMet backdoor The story of this backdoor is rather curious — ther...

CVE-2022-35798: Azure Arc Jumpstart Information Disclosure Vulnerability

**What is the nature of this vulnerability?** An information disclosure vulnerabilty exists in Azure Arc Jumpstart that could allow an authenticated user to view certain credentials and other senstive information contained in a log file. **What are the circumstances leading to a successful exploitation?** The client virtual machine is protected behind a secured Azure virtual network (VNET) without access from the internet. A potential attacker would first have to compromise the VNET to have network access to the Azure client virtual machine (Azure Arc Jumpstart-Client). There is only one provisioned user on the client virtual machine, and this user’s credentials are protected by a username and password provided by the end-user at deployment time. There are no other “low level” users that have login access to the virtual machine. The only user credential with access to the VM is the one created and supplied by the original Azure Arc Jumpstart end-user. A potential attacker would firs...
