A Noteworthy Threat: How Cybercriminals are Abusing OneNote
Threat actors are taking advantage of Microsoft OneNote's ability to embed files and use social engineering techniques, such as phishing emails and lures inside the OneNote document, to get unsuspecting users to download and open malicious files.
Threat Spotlight: XLLing in Excel - threat actors using malicious add-ins
As more and more users adopt new versions of Microsoft Office, it is likely that threat actors will turn away from VBA-based malicious documents to other formats such as XLLs or rely on exploiting newly discovered vulnerabilities to launch malicious code.
The Zimperium zLabs team recently discovered a malicious browser extension, originally called Cloud9, which not only steals the information available during the browser session but can also install malware on a user's device and subsequently assume control of the entire device. In this blog, we will take a deeper look into this malicious browser extension.
Malicious Cookie Stuffing Chrome Extensions with 1.4 Million Users
A few months ago, we blogged about malicious extensions redirecting users to phishing sites and inserting affiliate IDs into cookies of eCommerce sites. Since that time, we have investigated several other malicious extensions and discovered 5 extensions with a total install base of over 1,400,000 "...the extensions also track the user’s browsing activity."
Google Online Security Blog: The Package Analysis Project: Scalable detection of malicious open source packages
Despite open source software’s essential role in all software built today, it’s far too easy for bad actors to circulate malicious packages that attack the systems and users running that software. Unlike mobile app stores that can scan for and reject malicious contributions, package repositories have limited resources to review the thousands of daily updates and must maintain an open model where anyone can freely contribute. As a result, malicious packages like ua-parser-js, and node-ipc are regularly uploaded to popular repositories despite their best efforts, with sometimes devastating consequences for users.
