Microsoft Will Block Dangerous File Types in OneNote Documents
Last year, Microsoft started blocking macros by default in Office files delivered via the Internet to make it harder for malicious actors to use macros for delivering malware. In response, threat actors have been looking for alternative methods for malware delivery, such as OneNote files. OneNote is a digital note-taking application that is part of the Microsoft Office suite and it has been proving popular for malware distribution because executable files can be embedded in OneNote documents. These files are usually hidden behind design elements in the documents, such as buttons instructing users to click to view the content. The user is informed that they need to double-click the button, but doing so executes the hidden embedded executable file behind the button. If executed, the hidden executable file downloads a malicious payload from a remote server.

In response to the increasing misuse of OneNote files in phishing campaigns,...

A U.S. District Court Judge has denied class certification in a long-running legal battle against CareFirst BlueCross BlueShield over its 2014 data breach that affected 1.1 million plan members.

The lawsuit was initially filed in 2015 but was dismissed by a lower court in 2016 due to lack of injury, but was resurrected by a federal appeals court in 2017. In 2018, the U.S. Supreme Court declined CareFirst’s request for review and the case was returned to the District Court for the District of Columbia and was allowed to proceed. The lawsuit alleged CareFirst had failed to implement appropriate security measures and made several errors that allowed hackers to breach its network and access the data of its customers, and as a result of the data breach, class members face an...
