Google Issues Warning For 2 Billion Chrome Users

Chrome’s 2.6 Billion users need to be alert again (for the 2nd time in a week), as Google has confirmed multiple high-level hacks to the browser.

Just days after Chrome’s 12th (and 13th) ‘zero-day’ exploits this year were discovered, Google published a blog post that revealed four vulnerabilities. Users must take immediate action.

Google currently restricts information about hacks in order to make it easier for Chrome users to upgrade. This is a standard practice. We have only the following information:

  • High – CVE-2021-37977 : Use after free in Garbage Collection. Report by Anonymous, 2021-09-24
  • High CVE-2021-377978 : Blink buffer overflow. Reported by Yangkang, @dnpushme, of 360 ATA on 2021/08/04
  • High CVE-20237979 : WebRTC buffer overflow. Report by Marcin Towalski, Cisco Talos, on 2021-09/07.
  • High – – Inappropriate Implementation in Sandbox. Reported by Yonghwi Jin, @jinmo123, on 2021-09-30

These descriptions don’t offer much insight, but it’s interesting to see Chrome continue to be attacked with ‘Use After-Free’ ( UAF). In September, the browser was subject to double-digit UAF attacks. This month, hackers exploited a zero day UAF flaw in chrome.

It was less surprising to see a pair Heap buffer overload exploits listed. This is a memory vulnerability, also known as Heap Smashing. However, it is not a common avenue for Chrome hackers in recent months. The heap contains program data and is dynamically allocated. Critical data structures may be overwritten by an overflow making it a prime target for attackers.

Google responded by releasing a critical update. Google warns Chrome users that rollouts will be delayed so that not all will be protected immediately. To verify if you are safe, go to Settings >Help > About Google Chrome. You are safe if your Chrome version is at least 94.0.4606.81. You can still update your browser if the update is not available.

Remember the last step after you have updated Chrome: Chrome cannot be restarted until it is safe again. This makes it a two-way operation. Google can speed track fixes to Chrome hacks but users will not be protected if they do not restart their browsers after updating. Hackers count on this false sense of security. Go check your browser now.

Google Workspace vs. Microsoft 365: What’s the best office suite for business?

Published

Google G Suite vs. Microsoft Office

Once upon a time, Microsoft Office ruled the business world. By the late ‘90s and early 2000s, Microsoft’s office suite had brushed aside rivals such as WordPerfect Office and Lotus SmartSuite, and there was no competition on the horizon.

Then in 2006 Google came along with Google Docs & Spreadsheets, a collaborative online word processing and spreadsheet duo that was combined with other business services to form the Google Apps suite, later rebranded as G Suite, and now as Google Workspace. Although Google’s productivity suite didn’t immediately take the business world by storm, over time it has gained both in features and in popularity, boasting 6 million paying customers, according to Google’s most recent public stats in March 2020.

Microsoft, meanwhile, has shifted its emphasis away from its traditional licensed Office software to Microsoft 365 (formerly Office 365), a subscription-based version that’s treated more like a service, with frequent updates and new features. Microsoft 365 is what we’ve focused on in this story.

Nowadays, choosing an office suite isn’t as simple as it once was. We’re here to help.

Google Workspace vs. Microsoft 365

Google Workspace and Microsoft 365 have much in common. Both are subscription-based, charging businesses per-person fees every month, in varying tiers, depending on the capabilities their customers are looking for. Although Google Workspace is web-based, it has the capability to work offline as well. And while Microsoft 365 is based on installed desktop software, it also provides (less powerful) web-based versions of its applications.

Both suites work well with a range of devices. Because it’s web-based, Google Workspace works in most browsers on any operating system, and Google also offers mobile apps for Android and iOS. Microsoft provides Office client apps for Windows, macOS, iOS, and Android, and its web-based apps work across browsers.
