New SH1MMER Exploit for Chromebook Unenrolls Managed ChromeOS Devices

New SH1MMER Exploit for Chromebook Unenrolls Managed ChromeOS Devices
Feb 01, 2023 Enterprise Security
A new exploit has been devised to "unenroll" enterprise- or school-managed Chromebooks from administrative control. Enrolling ChromeOS devices makes it possible to enforce device policies as set by the organization via the  Google Admin console , including the features that are available to users. "Each enrolled device complies with the policies you set until you wipe or deprovision it," Google  states  in its documentation. That's where the  exploit  – dubbed Shady Hacking 1nstrument Makes Machine Enrollment Retreat aka  SH1MMER  – comes in, allowing users to bypass these admin restrictions. The method is also a reference to shim, a Return Merchandise Authorization (RMA) disk image used by service center technicians to reinstall the operating system and run diagnosis and repair programs. The Google-signed  shim image  is a "combination of existing Chrome OS  factory bundle  components" – namely a release image, a toolkit, and the firmware, amon

Yes, you could earn $100,000 if you have the hacking skills and love to play with electronics and gadgets. Google has doubled its top bug bounty for hackers who can crack its Chromebook or Chromebox machine over the Web . So if you want to get a big fat check from Google, you must have the ability to hack a Chromebook remotely, that means your exploit must be delivered via a Web page. How to Earn $100,000 from Google The Chrome security team announced Monday that the top Prize for hacking Chromebook remotely has now been increased from $50,000 at $100,000 after nobody managed to successfully hack its Chromebook laptops last year. The Top bug bounty will be payable to the first person – the one who executes a ' persistent compromise ' of the Chromebook while the machine is in Guest Mode . In other words, the hacker must be able to compromise the Chromebook when the machine is in a locked-down state to ensure its user privacy.  Moreover, the hack

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Google announces $2.7 million Reward for hacking Chrome OS at Pwnium Contest
Jan 27, 2014
Pwnium is the annual Hacking competition where Google invites coders from around the world to find security holes in Google Chrome. Google has announced its 4th Pwnium Hacking Contest hosted at the Canadian Security conference in March, offering more than $2.7 million in potential rewards for hacking Chrome OS-running ARM and Intel Chromebook. This year the security researchers have a choice in between an ARM-based Chromebook, the HP Chromebook 11 (WiFi) and the Acer C720 Chromebook (2GB WiFi) based on Intel's Haswell microarchitecture . The attack must be demonstrated against one of these devices running " then-current " stable version of Chrome OS. " Security is a core tenet of Chromium, which is why we hold regular competitions to learn from security researchers. Contests like Pwnium help us make Chromium even more secure ," Jorge Lucángeli Obes, Google Security Engineer said. Amongst the payouts are $110,000 for the browser or s
