Post-Quantum Cryptography: Standards and Progress (Google Online Security Blog)

Actualités, Sécurité
Posted by Royal Hansen, VP, Privacy, Safety and Security Engineering, Google, and Phil Venables, VP, TI Security & CISO, Google Cloud The National Institute of Standards and Technology (NIST) just released three finalized standards for post-quantum cryptography (PQC) covering public key encapsulation and two forms of digital signatures. In progress since 2016, this achievement represents a major milestone towards standards development that will keep information on the Internet secure and confidential for many years to come. Here's a brief overview of what PQC is, how Google is using PQC, and how other organizations can adopt these new standards. You can also read more about PQC and Google's role in the standardization process in this 2022 post from Cloud CISO Phil Venables. What is PQC? Encryption is central to keeping information…

Android 14 Adds New Security Features to Block 2G Exploits and Baseband Attacks

Actualités
Google has revealed the various security guardrails that have been incorporated into its latest Pixel devices to counter the rising threat posed by baseband security attacks. The cellular baseband (i.e., modem) refers to a processor on the device that's responsible for handling all connectivity, such as LTE, 4G, and 5G, with a mobile phone cell tower or base station over a radio interface.

Pixel’s Proactive Approach to Security: Addressing Vulnerabilities in Cellular Modems

Actualités
Posted by Sherk Chung, Stephan Chen, Pixel team, and Roger Piqueras Jover, Ivan Lozano, Android team Pixel phones have earned a well-deserved reputation for being security-conscious. In this blog, we'll take a peek under the hood to see how Pixel mitigates common exploits on cellular basebands. Smartphones have become an integral part of our lives, but few of us think about the complex software that powers them, especially the cellular baseband – the processor on the device responsible for handling all cellular communication (such as LTE, 4G, and 5G). Most smartphones use cellular baseband processors with tight performance constraints, making security hardening difficult. Security researchers have increasingly exploited this attack vector and routinely demonstrated the possibility of exploiting basebands used in popular smartphones. The good news is that Pixel has…

Evaluating Mitigations & Vulnerabilities in Chrome

Actualités
Posted by Alex Gough, Chrome Security Team The Chrome Security Team is constantly striving to make it safer to browse the web. We invest in mechanisms to make classes of security bugs impossible, mitigations that make it more difficult to exploit a security bug, and sandboxing to reduce the capability exposed by an isolated security issue. When choosing where to invest it is helpful to consider how bad actors find and exploit vulnerabilities. In this post we discuss several axes along which to evaluate the potential harm to users from exploits, and how they apply to the Chrome browser. Historically the Chrome Security Team has made major investments and driven the web to be safer. We pioneered browser sandboxing, site isolation and the migration to an encrypted web. Today we’re…

The Secret Weakness Execs Are Overlooking: Non-Human Identities

Actualités
For years, securing a company’s systems was synonymous with securing its “perimeter.” There was what was safe “inside” and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem

New Perfctl Malware Targets Linux Servers for Cryptocurrency Mining and Proxyjacking

Actualités
Linux servers are the target of an ongoing campaign that delivers a stealthy malware dubbed perfctl with the primary aim of running a cryptocurrency miner and proxyjacking software. "Perfctl is particularly elusive and persistent, employing several sophisticated techniques," Aqua security researchers Assaf Morag and Idan Revivo said in a report shared with The Hacker News. "When a new user logs

North Korean Hackers Using New VeilShell Backdoor in Stealthy Cyber Attacks

Actualités
Threat actors with ties to North Korea have been observed delivering a previously undocumented backdoor and remote access trojan (RAT) called VeilShell as part of a campaign targeting Cambodia and likely other Southeast Asian countries. The activity, dubbed SHROUDED#SLEEP by Securonix, is believed to be the handiwork of APT37, which is also known as InkySquid, Reaper, RedEyes, Ricochet Chollima,
