The Microsoft cloud’s security was recently tested when a vulnerability was uncovered in its Bing search engine, which ultimately led to the hijacking of users’ searches and the potential exposure of Office 365 data.
The Exploration of the Vulnerability
A German security researcher named ‘_’ recently reported to Microsoft a vulnerability in the Bing search engine. The vulnerability exposed certain Office 365 data of many users in plain text, as well as allowed for malicious actors to hijack user searches. Microsoft acted quickly to patch the vulnerability and release a statement on the incident.
In their brief statement, Microsoft stated that this security flaw was discovered in the Bing Image Search feature, which pointed users to third-party websites that could have potentially hosted malicious content. When this feature was used in conjunction with Office 365, user data was exposed in plaintext. Microsoft patched the vulnerability after the researcher reported it and thanked him for helping to keep their customers safe.
Risks To Businesses
The potential risks to businesses of any size should be taken seriously if they use Office 365. Having this type of data exposed could put companies and their customers at risk of malicious targeting. In addition, having their search engine hijacked could lead to a loss of user trust in the Microsoft cloud.
There are a few steps businesses can take to protect themselves from this type of vulnerability.
First, businesses should use strong authentication measures for any user accounts that have access to Office 365 data. This includes implementing multi-factor authentication, which can help ensure secure access.
Second, businesses should consider using secure web gateways to protect their Office 365 data. These gateways can help to monitor for any malicious activity and alert administrators of any potential threats.
Finally, businesses should always stay up to date on any security patches released by Microsoft. In the case of this vulnerability, Microsoft released a patch shortly after it was discovered and reported. Applying this patch could have helped to prevent any malicious activity from occurring.
Having a vulnerability in the Microsoft cloud can be a serious issue, as it can lead to the hijacking of user searches and the potential exposure of Office 365 data. To protect against any potential malicious activity, businesses should use strong authentication measures, utilize secure web gateways, and stay up to date on any security patches released by Microsoft.
