Last year, an astounding 51% of organizations were hit by ransomware, with attackers succeeding in encrypting data in 73% of attacks*.

You may need to convert the generated certificate file to.pem.crt or.cer file to be compatible with the chrome book. OpenVPN with ChromeOS and Sophos UTM in Blog. I’m going to save a bunch of yak and discussion about things I’m not qualified to discuss. Instead, below is a step-by-step to get a Chromebook or other ChromeOS device connecting to a Sophos UTM. Sophos Mobile 9.5 has been tested for accessibility and can now be used with screen readers. Chromebook Security Management. With version 9.5, Sophos Mobile now also supports the Chrome OS platform. To manage such devices, Sophos has first focused on Security Management rather than Chromebook Management. Sophos sells just one level of antivirus software: Sophos Home Premium, available in one-, two-, or three-year subscriptions, each of which protects up to 10 Windows or macOS PCs. Founded in 1985. Spend less time and effort managing and securing traditional and mobile endpoints with this complete UEM solution. Supports management of Android, iOS, Windows, macOS and Chromebook devices.
When you consider that a single full-scale attack can set the average business back by nearly $755,000 (USD)*, it’s clear that protecting all your devices and operating systems is not a ‘nice to have’ but a ‘must-have’.
Securing all the devices and platforms people use is also a key pillar in enabling secure remote working— desktops, laptops, mobile devices, Windows, macOS, Linux, Android, and iOS.
Protecting all your devices with Sophos
Sophos Intercept X gives you world-leading protection for your endpoints, servers and mobile devices. It uses multiple layers of technology to stop attackers at multiple points in the kill chain:
Anti-ransomware stops unauthorized encryption, rolling files back to their safe states.
Deep learning AI, developed by Sophos’ AI experts, blocks both known and never-before-seen malware with an incredibly low false-positive rate.
Anti-exploit technology stops exploits, active adversary techniques, and fileless and script-based attacks.
Foundational, signature-based technology stops known threats.
Whatever devices and platforms you use, Intercept X has got you covered:
- Intercept X endpoint secures desktops running Windows and macOS
- Intercept X for Server secures on-prem and cloud-based servers running Windows or Linux
- Intercept X also secures virtual desktops which are susceptible to the same threats as physical laptops.
- And Intercept X for Mobile secures mobile devices running Android, iOS and Chromebook.
Stop human-led attacks with human led-threat hunting
Sophos Chromebook User Id App
The most devastating cyber threats usually involve human-led attacks, often exploiting legitimate tools and processes such as PowerShell.
Hands-on live hacking enables attackers to bypass security products and protocols by modifying their tactics, techniques, and procedures (TTP) on the fly.
Stopping these human-led attacks requires human-led threat hunting.

Hunt down threats with Sophos EDR
Intercept X with EDR — Endpoint Detection and Response — give you the tools to carry out your own threat hunts from the same Sophos console you use to manage your endpoint and server protection.
It’s the first EDR designed for security analysts and IT administrators, so you can add expertise, not headcount.
Hunt for threats with Sophos EDR
Plus, in addition to enabling you to investigate suspicious signals and threats, Intercept X EDR also helps you improve your IT hygiene and identify configuration issues that leave you exposed. Common use cases include:
- Identify signs of attempted breaches
- Investigate phishing attacks
- Fix issues with Chrome running slowly
- Manage software compliance and licensing usage
Enlist Sophos’ expert threat hunters
If you don’t have the time, capacity, or skills to do threat hunting yourself, the Sophos Managed Threat Response service is here to help.
Our team of experts provide 24/7 detection and response capabilities delivered as a fully-managed service. They proactively hunt for and validate potential threats — and stop incidences before they cause harm.
Securing devices without compromising privacy
When it comes to securing your workforce, there’s one final consideration: employee-owned devices, aka BYOD. As an IT team, you want to manage and secure both company-owned and personal devices without compromising users’ privacy.
Sophos Mobile is a unified endpoint management solution that integrates natively with Sophos Intercept X and supports management of Windows 10, macOS, iOS, and Android devices.
It lets you secure any combination of personal and corporate-owned devices with minimal effort and is ideal for BYOD scenarios.

*The State of Ransomware 2020, Sophos
Almost exactly a month ago, or a couple of days under an average month given that February was the short one, we warned of a zero-day bug in Google’s Chromium browser code.
Sophos For Chromebook Windows 7
Patch now, we said.
And we’re saying it again, following Google’s otherwise cheery release of version 89.0.4389.72:
The Chrome team is delighted to announce the promotion of Chrome 89 to the stable channel for Windows, Mac and Linux. This will roll out over the coming days/weeks.
We’ve never quite understood Google’s mention of rolling out updates over “days/weeks” in an update bulletin that includes 47 security fixes, of which eight have a severity level of High.
In fact, we suggest going out manually and making sure you’ve got your Chrome update already, without waiting for those day/weeks to elapse until the update finds you.
If you’re using a Chromium-based product from another browser maker, check with that vendor for information about whether their build is affected by this bug, and if so whether the patch is downloadable yet.
Object lifecycle issue in audio
Two of the eight High Severity bugs in this set of patches were apparently found in the same part of Chrome, denoted in Google’s list merely as: Object lifecycle issue in audio. Reported by Alison Huffman, Microsoft Browser Vulnerability Research.
The first bug is numbered CVE-2021-21165, reported on 2021-02-04, a month ago; the second was dubbed CVE-2021-21166, reported a week after that on 2021-02-11.
An object lifecycle issue is a jargon way of referring to what probably amounts to some kind of memory mismanagement.
The word “object” refers, very loosely, to a block of memory containing some sort of data structure, together with a list of associated programmatic functions for manipulating that data.
Managing an object’s lifecycle means, amongst other things:
- Ensuring that the memory it uses is reclaimed by the system when the object is no longer needed.
- Taking care not to reclaim and reallocate the memory while the object is still being used.
- Not doing any calculations on the object before its memory has been assigned and initialised.
- Not doing the wrong sort of calculations on the data in an object, such as trying to treat a JPEG file as a PNG, or assuming that an audio clip has 16 bits per audio sample when it only has 8 bits.
- Stopping two different parts of the program from clashing over access to the object.

Exploit in the wild
We don’t know what form these particular bugs took, given that the Chromium team’s discussion of the bugs in this release still seems to be in “keep-it-private-to-stave-off-the-crooks-a-while-longer” mode.
But we do know that at the end of this month’s bug list you will see an almost casual sentence saying that:
Google is aware of reports that an exploit for CVE-2021-21166 exists in the wild.
In vernacular language, that means “this is a zero-day bug.”
In this context, “zero-day” denotes that the crooks got there first, so that there were literally zero days on which even the fastest-patching sysadmin could have been ahead of the Bad Guys.
Who’s exploiting this bug, in which parts of the world, against whom, and with what sort of outcome, we don’t yet know.
We’re assuming that some sort of remote code execution attack (RCE) is involved, in which case this bug, when successfully triggered, could lead to crooks implanting malware on your computer without you noticing at all, let alone agreeing to download or install any files.
We’re also assuming, given that this bug apparently has something to do with audio processing, that the bug can be deliberately and remotely triggered by serving up some audio-related data via a booby-trapped web page.
What to do?
As always in a zero-day report of this sort, don’t worry too much about the exact hows and whys just yet – assume that some kind of “drive-by” RCE is possible, so that just visiting a booby-trapped site might be enough to drop malware onto your computer, and therefore patch right away.
