Google boots fake Ad blockers from Chrome web store

A researcher with AdGuard discovered five fake ad-blocking extensions in the Chrome Web Store that used hidden scripts to manipulate users’ browsers. The good news is, after AdGuard published the report, the Chrome team removed all five of the extensions from its store.

Unfortunately, AdGuard’s Andrey Meshkov reports that the extensions he discovered had more than 20 million users. Posing as ad blockers, the malicious extensions simply copied code from real ad blockers and then added to them. “All the extensions I’ve highlighted are simple rip-offs with a few lines of code and some analytics code added by the ‘authors,’” Meshkov wrote.

These Chrome extensions can hijack computers to mine cryptocurrency and record your every move

Security researchers have uncovered 89 malicious Google Chrome extensions on the official Chrome store that can inject ads, code to secretly mine cryptocurrency, and load a tool to record and replay a person's browsing activities. This collection of extensions affected over 423,000 users and was used to form a new botnet called "Droidclub."

In November 2017, Princeton's Center for Information Technology highlighted the use of legitimate session-replay scripts on popular, high-traffic websites by third-party analytics firms. These scripts are used to record and replay a user's visit to a website, allowing the site owner to figure out what the user saw.

Google Chrome extensions with 500,000 downloads found to be malicious

Researchers have uncovered four malicious extensions with more than 500,000 combined downloads from the Google Chrome Web Store, a finding that highlights a key weakness in what's widely considered to be the Internet's most secure browser.

Google has since removed the extensions. Researchers stumbled on the find after detecting a suspicious spike in outbound network traffic coming from a customer workstation. They soon discovered it was generated by a Chrome extension called HTTP Request Header as it used the infected machine to surreptitiously visit advertising-related Web links.

Malicious Сhrome extension steals data posted to any website

Malicious browser extensions continue to bear fruit for hackers who have been using them to spread banking malware and adware, and hijacking popular add-ons to spread other nasty code.

The latest abuse involves a Google Chrome extension being spread in phishing emails that steals any data posted online by victims. This is a departure from previous attacks that monitor browser activity for specific URLs and extract credentials. This campaign may be limited to Brazil and other Portuguese-speaking nations, according to Renato Marinho, chief research officer at Morphus Labs and a SANS Internet Storm Center (ISC) handler.

After phishing attacks, Chrome extensions push adware to millions

Twice in five days, developers of Chrome browser extensions have lost control of their code after unidentified attackers compromised the Google Chrome Web Store accounts used to issue updates.

The most recent case happened Wednesday to Chris Pederick, creator of the Web Developer extension. Last Friday, developers of Copyfish, a browser extension that performs optical character recognition, also had their account hijacked. In both cases, the attackers used the unauthorized access to publish fraudulent updates that by default are automatically pushed to all Chrome users who have the extensions installed.

Google Chrome bug allows sites to spy on you by secretly recording audio and video

A new Google Chrome bug has been uncovered, which reportedly allows websites to record audio and video, without alerting the user or providing any visual indicators. Although the bug requires users to grant it permission to access audio and video features, it could potentially be used for spying on targets.

The bug was reportedly discovered by AOL developer Ran Bar-Zik, who reported the flaw to Google. However, Google said that it doesn't consider the issue to be valid security vulnerability, indicating that there is no quick fix on the way. Bar-Zik told that he came across the bug at work, when handling a website that ran WebRTC code.

Kovter trojan gets new persistence mechanism

The actor behind the Kovter Trojan has come up with a new persistence mechanism over the past weeks and also started masquerading the malware as a Chrome update, Microsoft security researchers warn.

It’s a well-known fact that cybercriminals are constantly updating their malicious applications to ensure increased efficiency, and the people behind Kovter have been very active in this regard over the past several months: in April, they added ransomware capabilities to this file-less Trojan, while starting to masquerade it as a Firefox update several weeks ago. Now, Microsoft Malware Protection Center researchers reveal that the actor has updated Kovter’s persistence method.

Irremovable bank data-stealing Android malware poses as Google Chrome update

A banking and personal information stealing mobile malware posing as a Google Chrome update for Android, and which can't be removed from the infected device, has been spotted in the wild by cybersecurity researchers.

The infostealer malware - discovered by the Zscaler ThreatLabZ research team - is capable of harvesting banking information, call logs, SMS data and browser history which are all sent to a remote command-and-control server. Rather than being served by one URL, the malware squats on multiple domains which are similar to existing Google updates.
