https://bit.ly/3s3yAAb - 🔒 In a recent 40-minute briefing, security experts Tomer Bar and Omer Attias of SafeBreach discussed the evolution of Endpoint Detection and Response (EDRs) and the importance of the signature update process in protecting against new threats. The briefing highlighted the security risks associated with update processes, referencing past attacks such as the infamous Flame malware. The presentation emphasized the need for proper protection measures against malicious code impersonation, even without a rogue certificate or MITM. #Security #EDRs #Malware 🛠 The researchers embarked on a journey into the architecture of Windows Defender, examining the signature database format and security verification logic. They revealed a shocking 0day vulnerability that allows an attacker to gain full control over Windows agents and servers worldwide. The risk extends to enterprise machines, including Microsoft 365 Defender. The vulnerability exposes systems to significant threats that were previously deemed improbable without state-backed capabilities. #WindowsDefender #0dayVulnerability #EnterpriseSecurity 📊 Unveiling their open-source tool, Defender-Pretender, the speakers demonstrated how an unprivileged user could neutralize EDRs, allowing known malicious code to run undetected. The tool further enables attackers to delete OS and driver files, leading to an unrecoverable OS, and alter Windows Defender's detection and mitigation logic. These revelations point to a serious security flaw in the current system and underscore the importance of vigilant protection against evolving cybersecurity threats.

EDRS-C mated with launcher The second satellite to join the constellation that forms the European Data Relay System (EDRS) has been mated with its launch vehicle. The EDRS-C satellite is due for launch on 6 August from Europe’s Spaceport in Kourou, French Guiana, aboard an Ariane 5 rocket. EDRS enables people to observe the Earth almost live, accelerating responses to emergency situations and spurring the development of new services and products that create jobs and increase prosperity. Dubbed the ‘SpaceDataHighway’ by its private operator, Airbus, EDRS uses innovative laser technology to dramatically cut the time needed for Earth observation satellites to deliver information to the ground. Instead of sending data from Earth observation satellites to the ground – which introduces delays of up to 90 minutes, as the information can only be transmitted when the satellite is in line-of-sight with the ground station – the system sends the data away from the Earth to the EDRS satellites that are in a higher, geostationary orbit. The EDRS satellites are in constant contact with their ground stations and can beam the data back down to Earth almost immediately. The satellites can transmit data at a rate of up to 1.8 Gbit/s. EDRS is a new, independent European satellite system, and is a public–private partnership between ESA and Airbus as part of ESA’s efforts to maximize the benefits to industry by taking an efficient management approach tailored to commercial best practices. “When EDRS-C joins its sister satellite EDRS-A in orbit, it will boost the capacity and reach of the system, which will enable companies in Europe and Canada to develop new services and products,” says Michael Witting, EDRS project manager at the European Space Agency. “ESA is helping to boost innovation by de-risking partners investments to meet market needs.”
