Posted on Monday February 26, 2018With evolving technology comes evolving threats. Recently, a researcher revealed that a new type of scam freezes Google Chrome and tricks users into believing that their network security has been compromised. Little did they know that following instructions listed on the screen will lead to an actual security breach.
The scam works by displaying an error message indicating a bogus security breach incident that renders a browser unusable. These scammers capitalize on the fact that a serious crash can't be solved by simply closing the site, thereby sending the users into a panic. This encourages them to dial the number listed on the warning message.
On the other end of the line, the scammers would pose as Microsoft or Apple representatives to convince users into surrendering their credit card details to repair a non-existing security issue. The scams are generally carried out through legitimate sites or malicious ads that have been hacked.
This new scam operates against Chrome by corrupting the window.navigator.msSaveOrOpenBlob programming interface, which basically uses it as a form of distraction. The hackers manipulate the browser and forces it to save a random document on a disk repeatedly at super fast intervals that are impossible to notice. After five to 10 seconds, Chrome will be completely unresponsive.
To recover, Windows users simply have to open Windows Task Manager (press ctrl + shift + esc keys) and stop the process there. On the other hand, macOS users just need to wait until a system message prompts them to close the unresponsive Chrome tab. Typically, the latter is a more appealing option since users would have the freedom to close only the corrupted page. Manually closing the whole browser means possibly losing unsaved files in any open Windows.
