Google has worked to guarantee users that the Chrome browser is safe and to use, with 3 safety updates in just 3 weeks. Despite a wonderful resolution to open a new online corporate store to attend assistance shields opposed to the safety risk opposed to malicious extensions, new studies have just revealed that any extension of the Chrome browser can be used to compromise its device . This is what you want to know.
As I reported on December 29, hackers employing compromised Chrome browser extensions to bypass two-factor authentication protections were underway. At least 35 corporations had their chrome extensions replaced with malicious versions in what gave the impression of a coordinated crusade of sophistication and scope and scope. At the time, Google Chrome’s security team said users were through a variety of methods, adding a tradition summary of all installed extensions, strict review policies before extensions were released, and non-stop tracking of their aftermath. “that an extension poses a serious threat to Chrome users,” Google said, “without delay has been removed from the Chrome web store, and the extension is disabled in all browsers that have installed it. “
From now on, Squarex Labs researchers have shown that “a complete acquisition of the browser and the device is imaginable with browser extensions”, and not just malicious; Piracy “only requires fundamental reading / writing capabilities provide in maximum extensions”, which puts “the extension user in danger for the browser synchronization attack. “
Chrome browser syncjacking attacks occur across three phases: profile, browser and device hijacking. But let’s start at the beginning, with the attack preparation. This requires the hacker to first register a domain to a Google Workspace account and then disable 2FA protections. A functional web browser extension is then created and published to the Chrome store which will be used later to retrieve these profile credentials. The extension is pushed onto the victim using any of the existing myriad phishing techniques. “Seeing that it only has basic read/write capabilities available to most popular extension,” the researchers said, “the victim installs the extension,” assuming it is safe. “Over time,” they continued, “the extension’s presence fades into the background as the victim returns to their daily routine.”
At some point in the near future, the extension is connected to the domain recorded above, take the credentials and complete the steps to log in the victim in one of the accounts created in the past. The result here is that the user is now connected to a controlled profile through the attacker, which allows you to disable security measures so that the browser is more open to attacks. Here is where things get interesting.
“The attacker opens the valid page in sync,” the researchers said, “and they use the malicious extension to modify the content of the page, convincing the victim to terminate the sync. “And, Boom: All locally stored data, which comes with Chrome passwords and browsing history, is now downloaded from the hacker-controlled account. But that’s still getting worse, the researchers said, “The next step is to reshape the total browser into a controlled browser controlled through the attacker. “This earlier despite the fact that everything takes control of the entire device.
The browser synchronization attack is dangerous, warned the Squarex Labs report, because, unlike the extension attacks reported in the past that require evolved social engineering, “adversaries only want a minimum and a small stage of social engineering, User interaction is almost required to execute this attack.
