News FYI

Pharmaceutical company AstraZeneca faced with the personal data leakage of its patients

The management of a large pharmaceutical company AstraZeneca confirmed that due to the inattention of one of the developers, a list of credentials from the internal networks of the organization was publicly available, which compromised the personal confidential data of patients

In 2021, the developer left the credentials for the AstraZeneca internal server on GitHub. These credentials allowed anyone to access the Salesforce test cloud environment that many companies often use to manage client databases, but AstraZeneca's test environment contained some patient data. Some of the data related to AZ&ME apps that offer discounts to patients who need medicines.

Dropbox data leak

Cloud service Dropbox faced a data leak after company employees fell for the tricks of intruders through phishing emails. The attackers managed to gain access to one of the company's GitHub organizations, and then stole data from 130 repositories.

The incident occurred on October 14, 2022, and was associated with a large-scale phishing campaign, which GitHub representatives had previously warned about. Let me remind you that as part of this scheme, scammers sent letters with fake notifications on behalf of the Circle CI service, which is used for continuous development and deployment.

Immediately after the detection of suspicious activity, attackers' access to GitHub was disabled. Dropbox security experts updated all compromised developer credentials and determined which customer data was exposed or stolen.

"To date, our investigation has found that the code accessed by this threat actor contained some credentials—primarily, API keys—used by Dropbox developers," Dropbox revealed on Tuesday.
