Malicious Browser Extensions Infect Over 700 Users Across Latin America Since Early 2025

Jun 08, 2025 Malware / Browser Security
Cybersecurity researchers have shed light on a new campaign targeting Brazilian users since the start of 2025 to infect users with a malicious extension for Chromium-based web browsers and siphon user authentication data. "Some of the phishing emails were sent from the servers of compromised companies, increasing the chances of a successful attack," Positive Technologies security researcher Klimentiy Galkin said in a report. "The attackers used a malicious extension for Google Chrome, Microsoft Edge, and Brave browsers, as well as Mesh Agent and PDQ Connect Agent." The Russian cybersecurity company, which is tracking the activity under the name Operation Phantom Enigma , said the malicious extension was downloaded 722 times from across Brazil, Colombia, the Czech Republic, Mexico, Russia, and Vietnam, among others. As many as 70 unique victim companies have been identified. Some aspects of the campaign were disclosed in early April by a researcher who goes by th...
Popular Chrome Extensions Leak API Keys, User Data via HTTP and Hard-Coded Credentials

Popular Chrome Extensions Leak API Keys, User Data via HTTP and Hard-Coded Credentials

Jun 05, 2025 Browser Security / Online Safety
Cybersecurity researchers have flagged several popular Google Chrome extensions that have been found to transmit data in HTTP and hard-code secrets in their code, exposing users to privacy and security risks. "Several widely used extensions [...] unintentionally transmit sensitive data over simple HTTP," Yuanjing Guo, a security researcher in the Symantec's Security Technology and Response team, said . "By doing so, they expose browsing domains, machine IDs, operating system details, usage analytics, and even uninstall information, in plaintext." The fact that the network traffic is unencrypted also means that they are susceptible to adversary-in-the-middle (AitM) attacks, allowing malicious actors on the same network such as a public Wi-Fi to intercept and, even worse, modify this data, which could lead to far more serious consequences. The list of identified extensions are below - SEMRush Rank (extension ID: idbhoeaiokcojcgappfigpifhpkjgmab) and P...

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something’s wrong. This week’s stories aren’t just about what was attacked—but how easily it happened. If we’re only looking for the obvious signs, what are we missing right in front of us? Here’s a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks.

If this had been a security drill, someone would’ve said it went too far. But it wasn’t a drill—it was real. The access? Everything looked normal. The tools? Easy to find. The detection? Came too late. This is how attacks happen now—quiet, convincing, and fast. Defenders aren’t just chasing hackers anymore—they’re struggling to trust what their systems are telling them. The problem isn’t too few alerts. It’s too many, with no clear meaning. One thing is clear: if your defense still waits for obvious signs, you’re not protecting anything. You’re just watching it happen. This recap highlights the moments that mattered—and why they’re worth your attention. ⚡ Threat of the Week APT41 Exploits Google Calendar for Command-and-Control — The Chinese state-sponsored threat actor known as APT41 deployed a malware called TOUGHPROGRESS that uses Google Calendar for command-and-control (C2).
