Zoom Video Communications responded and released a security update on August 13 (local time) that fixes this vulnerability ( ZSB-22018) [2 Its Common Vulnerability Scoring System (CVSS) rating of 8.8 (critical) with a severity rating of "High".Īt DEFCON 30 Patrick Wardle, a Hawaii-based security researcher, demonstrated installing a malicious code that can modify, delete, or add files on MacOS, using this vulnerability. However, The Zoom Client for Meetings for macOS version 5.7.3 and before 5.11.5 contains a vulnerability that a local user with low privileges can get root privileges (CVE-2022-28756). Nowadays Zoom is an essential tool for our business. Zoom client on MacOS had privilege escalation vulnerability - DEFCON30 SpaceX told that normal Starlink users do not need to worry about the consequences of this attack and do not need to take any countermeasures. However, SpaceX stressed that this is only possible if there is physical access to the dedicated antenna and attach wires and components. SpaceX released a six-page PDF that addresses Wouters' attack method, praising Wouters' security research and acknowledging that the attack is possible. ![]() Wouter demonstrated this attack at Black Hat this year. That attack bypasses user privilege management and the attacker gains root privileges on a system allowing the attacker to execute an arbitrary code. ![]() Once Wouter's "Modchip" is attached to the Starlink circuit, the "ModChip” can execute a Fault Injection attack (an attack that instantaneously alters the electrical input of the processor) to the Starlink (UT). To access the Starlink User Terminal (UT) you need the Starlink antenna and circuit board. Recently Ukraine deployed many Starlink terminals in the warzone to secure internet access.Ī custom circuit board "Modchip" which costs only $25 is used for this attack. Starlink provides internet access anywhere in the world even if there is no internet infrastructure. Hack the SpaceX Starlink Terminal just 25$ - Black Hat USA 2022Īt Black Hat USA, "Glitched on Earth by Humans: A Black-Box Security Evaluation of the SpaceX Starlink User Terminal" , Belgian researcher Lennert Wouter presented a demo of hacking the Starlink terminal - a communications service operated by Elon Musk's SpaceX that provides internet access.
