Our reporting this week highlighted that nation-state actors in countries engaged in conflict continue to focus on intelligence gathering campaigns that could enable kinetic military activity. For example, the Iranian cyber espionage unit UNC3890 has been observed launching multiple campaigns against entities based in Israel. Both countries have been engaged in a proxy-conflict spanning decades, which further strengthens the assessment that this activity was perpetrated by an Iranian adversary. In this latest campaign, UNC3890 targeted multiple sectors, including maritime which we assess to be a focus for military intelligence collection.

Additionally, the Russian nation-state unit Gamaredon (also tracked as Shuckworm and Armageddon) has targeted Ukrainian organisations with information stealing malware and multiple backdoors, including the Pteranodon backdoor that the threat group was observed deploying in April 2022. The backdoors are capable of audio recording through the device microphone, screen capture, keylogging, and launching executable files, that facilitate intelligence gathering operations. This is one of multiple campaigns launched by Gamaredon against Ukrainian entities since the start of the Russo-Ukrainian war in late February 2022, which are likely to persist as the war continues unabated.

Key Vulnerabilities

  1. CVE-2022-27255
    A critical vulnerability (CVSS: 9.8|OVSS: 42) affecting networking devices built with Realtek SDK RTL819x system-on-chip that could allow a remote adversary to crash a device, execute arbitrary code, establish backdoors for persistence, and reroute or intercept network traffic. Researchers have developed proof-of-concept exploit code for this vulnerability.
  2. CVE-2022-2480
    A memory corruption vulnerability (CVSS: 8.8|OVSS: 50), also known as use after free, in the Service Worker API in Google Chrome (versions prior to 103.0.5060.134) that enables a remote adversary to exploit heap corruption via a crafted HTML page. ‘Use after free’ refers to a memory corruption vulnerability that occurs when an application tries to use memory that is no longer assigned to it.
  3. CVE-2022-2481
    A memory corruption vulnerability (CVSS: 8.8|OVSS: 37), also known as use after free, affecting Views in Google Chrome (versions prior to 103.0.5060.134) that allows a remote threat actor to exploit heap corruption via user interface interaction, after having convinced a user to engage in specific user interactions. This vulnerability is currently being exploited in the wild

What is OVSS?

The Orpheus Vulnerability Severity Score (OVSS) helps companies understand the risk associated with particular vulnerabilities. Orpheus does this by adding additional context on the likely threat to and impact of CVEs, building upon the vulnerability information that is provided as part of the CVSS (Common Vulnerabilities Scoring System) score.
