Defending the power grid against supply chain attacks—Part 1: The risk defined
Most people don’t think about electricity. If the internet works, their food is refrigerated, and their debit card is approved, why should they? Its ubiquity and reliability render it invisible—a bit of magic that powers much of modern life. That is, until a large storm passes through. Localized...
MGASA-2020-0089 Updated kernel-linus packages fix security vulnerabilities
This update provides upstream 5.4.20, adding support for new hardware and features, and resolves at least the following security issues: In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This...

Lenovo, HP, Dell Peripherals Face Unpatched Firmware Bugs
Fresh firmware vulnerabilities in Wi-Fi adapters, USB hubs, trackpads and cameras are putting millions of peripheral devices in danger of a range of cyberattacks, according to research from Eclypsium. TouchPad and TrackPoint firmware in Lenovo Laptops, HP Wide Vision FHD camera firmware in HP...
OpenSSH now supports FIDO U2F security keys for 2-factor authentication
Here's excellent news for sysadmins. You can now use a physical security key as hardware-based two-factor authentication to securely log into a remote system via SSH protocol. OpenSSH, one of the most widely used open-source implementations of the Secure Shell SSH Protocol, yesterday announced th...

Escaping the Chrome Sandbox with RIDL
Guest blog post by Stephen Röttger tl;dr: Vulnerabilities that leak cross process memory can be exploited to escape the Chrome sandbox. An attacker is still required to compromise the renderer prior to mounting this attack. To protect against attacks on affected CPUs make sure your microcode is u...
DNSSEC Keysigning Ceremony Postponed Because of Locked Safe
Interesting collision of real-world and Internet security: The ceremony sees several trusted internet engineers a minimum of three and up to seven from across the world descend on one of two secure locations -- one in El Segundo, California, just south of Los Angeles, and the other in Culpeper,...
TCP SACK PANIC
A Linux kernel vulnerability in TCP networking could allow DoS CVE-2019-11477 is considered an Important severity, whereas CVE-2019-11478 and CVE-2019-11479 are considered a Moderate severity. The first two are related to the Selective Acknowledgement SACK packets combined with Maximum Segment Si...
CVE-2019-16336
The Bluetooth Low Energy implementation in Cypress PSoC 4 BLE component 3.61 and earlier processes data channel frames with a payload length larger than the configured link layer maximum RX payload size, which allows attackers in radio range to cause a denial of service crash via a crafted BLE Li...
Building on secure productivity
Among the most common and powerful attack vectors we have seen are those that exploit the daily tradeoff users make between security and productivity. Often, this can be as simple as a document hiding an exploit or a malicious link. As an industry, we’re used to thinking of security and...
Reverse Engineering Tesla Hardware
TL;DR How does the Tesla Model S update its firmware? What did we find when reverse engineering the display and instrument cluster? Here’s the result of a couple of weeks work, working on a real vehicle that mostly worked after we had finished. Part 1: analysing the hardware, complete with a 14...

Guarding against supply chain attacks—Part 2: Hardware risks
The challenge and benefit of technology today is that it’s entirely global in nature. This reality is brought into focus when companies assess their supply chains, and look for ways to identify, assess, and manage risks across the supply chain of an enterprise. Part 2 of the “Guarding against...
