AMD flaws | Breaking Cybersecurity News | The Hacker News

AMD processors from as early as 2011 to 2019 carry previously undisclosed vulnerabilities that open them to two new different side-channel attacks, according to a freshly published research. Known as " Take A Way ," the new potential attack vectors leverage the L1 data (L1D) cache way predictor in AMD's Bulldozer microarchitecture to leak sensitive data from the processors and compromise the security by recovering the secret key used during encryption. The research was published by a group of academics from the Graz University of Technology and Research Institute of Computer Science and Random Systems (IRISA), who responsibly disclosed the vulnerabilities to AMD back in August 2019. "We are aware of a new white paper that claims potential security exploits in AMD CPUs, whereby a malicious actor could manipulate a cache-related feature to potentially transmit user data in an unintended way," AMD said in an advisory posted on its website over the weekend...

AMD has finally acknowledged 13 critical vulnerabilities, and exploitable backdoors in its Ryzen and EPYC processors disclosed earlier this month by Israel-based CTS Labs and promised to roll out firmware patches for millions of affected devices 'in the coming weeks.' According to CTS-Labs researchers, critical vulnerabilities ( RyzenFall, MasterKey, Fallout, and Chimera ) that affect AMD's Platform Security Processor (PSP) could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. Although exploiting AMD vulnerabilities require admin access, it could help attackers defeat important security features like Windows Credential Guard, TPMs, and virtualization that are responsible for preventing access to the sensitive data from even an admin or root account. In a press release published by AMD on Tuesday, the company downplays the threat by saying that, "any attacker gaining unauthorised ad...

The Need For Unified Security Google Workspace is where teams collaborate, share ideas, and get work done. But while it makes work easier, it also creates new security challenges. Cybercriminals are constantly evolving, finding ways to exploit misconfigurations, steal sensitive data, and hijack user accounts. Many organizations try to secure their environment by piecing together different security tools, hoping that multiple layers of protection will keep them safe.  But in reality, this patchwork approach often creates blind spots, making it harder—not easier—to defend against threats. To truly secure Google Workspace, businesses need a unified security strategy that offers complete protection without unnecessary complexity. The problem with most security solutions is that they only solve part of the puzzle. Point solutions, like tools that block malware or phishing attacks, might work well for a specific type of threat but fail to recognize suspicious user behavior, unauthori...
