Last July, a ransomware prank was found making the rounds on Safari browsers, which tied up the browser window with excessive pop-ups purporting to be from the FBI, demanding users send $300 to have their browser unlocked. The ransomware wasn’t harmful to the user’s system, and it could be easily bypassed. Well, we’re seeing yet another round of this irritating prank, and this time it affects Chrome and Safari browsers.
There’s a couple ways to kill this prank from each of the affected web browsers.
If you see this in the Google Chrome browser, following are instruction for two ways to clear this threat from Chrome:
1. Create a new cache directory in Terminal
Launch Chrome with a new cache directory by typing a Terminal command:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome –disk-cache-dir=/tmp
After this, quit Chrome then delete the files in this folder:
2. Clear related data in Chrome
You can type in the URL:
Then, clear any data that appears to be related to this prank.
If you see this in the Safari browser, following are instructions for two ways to clear this threat from Safari:
1. Reset Safari
In the Safari menu, choose “Reset Safari.” The browser will restart without bringing up the problematic site. It will, however, erase a lot of other historical, saved data.
2. Force Quit + Hold Shift Key While Restarting Safari
The other tactic simply targets the function that resumes open windows after a crash, which can be done by holding the Shift key while starting Safari.
First you will need to force-quit Safari as you would expect, either by going to the Apple menu and choosing “Force Quit” and choosing to quit Safari, or by using the keyboard-combination Command + Option + Escape to bring up the same window.
The second step is to hold the Shift key while restarting Safari, which restarts the browser without restarting any previously open windows.
We also encourage anyone who encounters ransomware to send the files to firstname.lastname@example.org for further analysis.
