Google Chrome – New Disadvantage Warning
As the “dirt” attacks go, it takes a few beats. A new report suddenly warns that a basic weakness in the way Google Chrome works and other chrome browsers mean password managers, cryptic wallets and other sensitive data are at risk. Just a single click on a middle speed can see you lose all your passwords. And the same attack can explode in banking applications, cryptic wallets and file stores.

The report comes through Squarex, whose research team “revealed a way to malicious supplements to silently falsify any extension installed in the victim’s browser.” The Director General of the company warned me that “the resolution of this will require a major adjustment to ensure that such attacks are not possible.” In short, users have been misled to install benign supplements for their browser which perform useful tasks as expected. But once installed, the stretch changes its shape and icon to perfectly imitate any of your most sensitive applications. When you click next, you fall victim to.
“Imagine your transcript tool he forms in your password manager,” the report says, “then your cryptocurrency portfolio and finally in your bank app – all without your knowledge. This is exactly what polymorphic supplements can do.”
These copies allowances are scary good. As with other attacks, it makes the discovery more difficult. “A perfect copy of the target icon pixel, Popup HTML, workflows and even temporarily disabling legitimate extent, making it extremely compelling for victims to believe that they are providing credentials for true extent.
The Squarex report determines the methodology by which a whole password can be stolen. Step by step. And all it takes is a wrong click.
“1. The attacker creates and publishes polymorphic extension in Chrome Store, disguised as a marketing tool.
2 Through various social engineering (eg social media) tactics, the victim discovers and installs the extension from Chrome Store.
3 During the installation process, a popup seems to drive the user to set the stretch for a better experience.
4. Extension works as promised, providing he marketing skills for the victim to stay under the radar. “
With that killer click, the attack determines “which stretch to impose”. Trojan extension should not be able to report again to other installed additions – but can. “While direct monitoring of other additions is prohibited by the Chrome stretch subsystem, there are other ways this may happen. The first way is to use API Chrome.Managent, an API used by many administrator tools to manage installed applications, including browser. unique online related to popular target supplements. “
Squarex uses the example of the popular 1 Password. “Discovering a PNG file containing the 1 Password logo is likely to mean that the password manager is installed in the victim’s browser.” With this done, the next stage of the attack can begin:
“5. The deliberate extension injects a scenario into any open file in the victim’s browser, which instructs the website to check the presence of online resources related to specific target additives, in this case 1 Password.
6. Results from this internet resource stroke have been sent back to the attacker server. If an objective is identified, the attacker will continue in phase 3. If not, the polymorphic extension will remain sleepy, periodically injecting the same scenario until an appropriate target is installed.
7. The victim lands on the access page of a Saas app (eg Salesforce) and clicks in the form of input.
8 This causes polymorphic extension to:
- Temporarily deactivate 1 Password, removing it from the hanging file
- Impose 1 Password, most importantly its icon in the dependent tab
9. A HTML popup seems to say the victim is entered by 1 Password and makes the victim re-laogin in 1 password through the alignment.
10. The victim clicks on the fake stretch icon, opening a perfect copy of the 1 Password’s entry page.
11. Understandably, the victim enters their username, password and secret key, which is sent to the attacker’s server.
12 Once the credentials are presented, the polymorphic extension is moved back to its original appearance and re-functioning 1 Password.
13. Real 1 Password authorizes the victim’s credentials, allowing them to register without a doubt that the sequence is arranged with it. “
All passwords stored in the password manager can now be used to access other platforms, “to exfield data or even impose the victim to spread phishing campaigns on the victim’s contacts.”
Stretching attack
This is not just a password attack, of course. The same approach can be used to start cryptocurrency portfolio transfers, accessing a victim’s bank applications and stealing documents. The research team points to the “human tendency to rely on visual signs as a confirmation” as the reason the threat from this new Atack is so dangerous. Clearly, the risk lies in the initial stretch installation and then promoting the only click. This is just the latest stretch warning to hit users in recent months.

While this is not just a chrome issue, the browser remains the gorilla in the cage when it comes to chrome, dominating the market. Squarex says that “Given that the attack exploits a legitimate functionality in Chrome, this attack cannot be resolved by joining the browser. However, we have written Chrome for responsible discovery.”
I have asked Google any comment on the new report.
“Millions of people rely on password managers based on expansion of browser and cryptic wallets to store credentials and valuable assets,” Vivek Ramacandran of Squarex told me. “These credentials can then provide the attackers with full unauthorized access to the target extension and do everything from the extension of all credentials stored in the password manager until the victim’s crypt.”
