Did you know that the default “copy link” option in O365 personal accounts generates a public shared link with edit permissions? In this edition, we will cover how link sharing in O365 can lead to the accidental internal and public exposure of sensitive data.
“Send it to the cloud” has been the increasingly common response over the years for dealing with the issue of how to handle massive amounts of data. On one side, I understand it. Another infrastructure owned by a third party who has teams dedicated to implementing security by design, continuous testing and validation – this all sounds attractive.
There’s no doubt that the adoption of public cloud deployments has accelerated for most organizations recently. In fact, according to metrics released by Oracle recently, nearly half (49%) of all respondents to the Oracle and KPMG Cloud Threat Report expect to store most of their data in a public cloud by the end of 2020. Effectively managing the security and compliance of public cloud deployments can be tricky for many organizations.
Cloud computing provides undeniable benefits for storing and accessing electronic health records. Files stored in the cloud are accessible anytime and anywhere from any device, which makes it easy to share critical medical information between healthcare workers. But is cloud storage secure enough to store, access and transfer sensitive personal and medical information?
Threat actors are leveraging top tier cloud apps to host phishing baits. Netskope Threat Labs has identified an ongoing O365 phishing campaign hosted in Google App Engine with the credential harvester mostly hosted in Azure App Service. This phishing campaign typically targets O365 users via phishing emails with a direct link or attachment.
Cloud misconfigurations are no laughing matter. In its “2020 Cloud Misconfigurations Report,” DivvyCloud revealed that 196 separate data breaches involving cloud misconfigurations had cost companies a combined total of approximately $5 trillion between January 1, 2018 and December 31, 2019. The problem is that those costs could be even higher; as reported by ZDNet, 99% of IaaS issues go unreported.
A phishing campaign abused both the Google App Engine and the Azure App Service to steal victims’ Microsoft Outlook credentials. Netskope observed that the attack campaign started with a shortened link distributed by a phishing email. This link redirected a recipient of the email to a Google App Engine domain.
