US 2020 Presidential Apps Riddled with Tracking and Security Flaws
(published: September 17, 2020)
The Vote Joe 2020 application has been found to be potentially leaking personal data about voters. The app is used by the Joe Biden campaign to engage with voters and get supporters to send out promotional text messages. Using TargetSmart, an intelligence service, the app receives their predictions via API endpoint which has been found to be returning additional data. Voter preference and voter prediction could be seen, while voter preference is publically accessible, the information for TargetSmart was not meant to be publicly available. The app also let users from outside of the United States download, allowing for non-US citizens to have access to the data, as there was no email verification. Vote Joe isn’t the only campaign app with security issues, as the Donald Trump application exposed hardcoded secret keys in the APK.
Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data.

German Hospital Attacked, Patient Taken to Another City Dies
(published: September 17, 2020)
A failure in IT systems at Duesseldorf University Hospital in Germany has led to the death of a woman. In an apparent ransomware attack, the hospital’s systems crashed with staff unable to access data. While there was no apparent ransom note, 30 servers at the hospital had been encrypted last week, with a ransom note left on one server addressed to Heinrich Heine University. Duesseldorf police contacted the perpetrators to inform them they had attacked the hospital instead of the university, with the perpetrators providing decryption keys, however patients had to be rerouted to other hospitals and therefore a long time before being treated by doctors.
Recommendation: Educate your employees on the risks of opening attachments from unknown senders. Anti-spam and antivirus applications provided by trusted vendors should also be employed. Emails that are received from unknown senders should be carefully avoided, and attachments from such senders should not be opened. Furthermore, it is important to have a comprehensive and tested backup solution in place, in addition to a business continuity plan for the unfortunate case of ransomware infection.
