The Rust Security Response WG and the crates.io team were notified on 2022-05-02 of the existence of the malicious crate rustdecimal, which contained malware. The crate name was intentionally similar to the name of the popular rust_decimal crate, hoping that potential victims would misspell its name (an attack called "typosquattin
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.
“Dormant Colors”: Live Campaign With Over 1M Data Stealing Extensions Installed
The “Dormant Colors” is yet another vast campaign of malicious extensions with millions of active installations worldwide, this time with a color-related theme and full of deception all through the chain. It starts with the trickery malvertising campaign, continues with a crafty novel way to side-load the real malicious code without anyone noticing (until now!), and finally with stealing not only your searches and browsing data, but also affiliation to 10,000 targeted sites — a capability that is easily leveraged for targeted spear phishing, account takeover and credential extraction — all using this powerful network of millions of infected computers worldwide!
Malicious WhatsApp mod distributed through legitimate apps
The malicious version of YoWhatsApp messenger, containing Triada trojan, was spreading through ads in the popular Snaptube app and the Vidmate app's internal store.
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.
