Google’s corporate network security breach exposed at least three of its MacBook networks, exposing the company to security risks and potentially compromising data on thousands of customers, the company announced Monday.
Google’s Macbook networks include the Mac Pro, Macbook Air, Mac Pro Retina, and Macbook Pro 10, according to a blog post.
Google said it was investigating a “potential network security vulnerability” in the Macbooks and was working with its partners to “assess the impact on the affected Macs.”
The post, which was shared with the Associated Press, described how a group of hackers could gain access to a computer network and then use that information to compromise an Apple device, and the information could be used to log in to the computer.
It also said the information had been shared with Apple and Google, and that the company was working to “provide additional details to support our investigation.”
Google said its partners would “ensure their affected devices are updated and patched” as soon as possible.
It did not disclose what devices were affected.
Google did not respond to a request for comment.
Google has been grappling with the security of its mobile devices and has not been as vigilant about security around its enterprise network.
In August, it disclosed a data breach that affected millions of users, including Google’s Gmail service.
The breach was uncovered when the company discovered hackers had been able to gain access into its email accounts and other data.
Google was able to take back control of its Gmail services after it fixed the issue, but it has not yet released the names of the companies it believes are at risk.
The Macs could also be vulnerable to security breaches that could allow hackers to log into devices or compromise data on a company’s networks.
The vulnerability was first reported in April by security researchers from cybersecurity firm Kaspersky Lab.
Google said Monday it is working to address the issue by patching the vulnerable Macs and has “actively updated our support and customer contact lists to better protect users from this risk.”
The company said it is also investigating a second breach in which hackers could have accessed the network of a major U.S. telecommunications company, and it said that its researchers are working with that company to provide additional details.
Google also disclosed a security flaw that allowed an attacker to log onto the servers of a small U.K. telecommunications provider, which is owned by Google.
The attack was uncovered in March.
Google is working with Apple to address this breach.
The company is also working to patch the vulnerability in the Cisco Catalyst 7000 network, according a statement from Google.
Apple has been working with Google to patch a similar security flaw, and Apple is now working with Cisco to fix a security issue in its Cisco Catalyst 6500 network, a statement said.
Google is working on a patch for a Cisco Catalyst 6000 network, and Google said it has “further advanced our Cisco security efforts.”
Apple said in a statement that it is “working with Google on an updated version of the Mac operating system to address these vulnerabilities.”
