Metropolitan Police malware warning issued - beware the ransomware attack!

Filed Under: Law & order, Malware, Ransomware

Scotland YardComputerWorld today reports that the UK's Metropolitan Police has warned Windows users of a malware attack that poses as a message from the computer crime-fighting cops themselves.

The ransomware attack attempts to lock the computer, and posing as an unofficial notice from a law enforcement agency, claims that the victim's PC has been determined to have visited illegal websites.

Only payment for a fine, claims the message, will restore the computer's functionality.

Various versions of the alert messages have been seen - here's one example:

Ransomware message. Click for larger version

Part of the poorly-worded alert reads as follows:


The process of illegal activity is deleted. According to UK law and Metropolitan Police Service and Strathclyde Police investigation your computer is locked!

The following violation is detected: You IP-address "[redacted]". Forbidden websites containing pornography, child pornography, Sodomy and called violence against children on, violent material toward people were visited from this IP-address!

Moreover and e-mail spam was sent you're your computer, emails containing terroristic materials. This locking serves to stop your illegal activity.

To release a lock your computer you should pay the fine in amount of £100. In the case of ignoring the payment, the program will remove illegal materials while keeping your personal information is not guaranteed.

Of course, it's very likely that you haven't been visiting extremist websites or viewing child abuse material. That may just be the hook used by the fraudsters to trick you into taking the warning seriously.

Ransomware is nothing new. We've seen plenty of examples in the past where cybercriminals have duped users into coughing up cash in order to get their computer working properly again.

But the threat of legal action, and what - on first glance - might appear to some computer users to be a sign that they are in trouble with the police, could be enough to scare some into electronically transferring funds post haste.

The police recommend that anyone who is duped by the scam should contact their credit card company immediately, and underline that they would never use such tactics to make contact with the public or demand funds.

It's likely that the messages are appearing on computer users' screens because they have become infected whilst visiting compromised websites, or have been duped into installing malicious software onto their computer.

Sophos has linked Mal/Bredo-Q to some of the reports we have seen of this particular ransomware attack, but of course it's perfectly possible that malicious hackers could use other malware to display the same or similar messages posing as police warnings.

As always, keep your security patches and anti-virus solutions updated, and your wits about you.

    Anyone who can fall for a scam like that is pretty gullible. This is especially the case when it goes beyond obviously false claims and manages to be poorly worded as well.

    • Unfortunately the majority of people who have malware running on their systems are very gullible, which is why ransomware and malware such as Koobface and fake keygens are so widespread.

        My device was saying something about Malaware but when the message popped up it knew my for dinars

  5. This malware has been running in Germany very successfully for the last 2 - 3 years, I've had users actually pay 3 times to try and get rid of the virus, not realising it was a virus. The German version is word-perfect, if you had never seen this virus before you would be convinced big-brother was watching you and unless you entered the coupon code you would be hauled into prison by guys coming down ropes from a helicopter. I say running successfully because of the amount it requests, 100 Euro every time. Someone is retiring on this very successfully!

    Some useful info about how to clean the PC after this infection would be useful!

    I just tried to clean it off one our users' laptops by removing the HDD and connecting via a USB<->Sata box to a PC with Sophos, and from there doing a Sophos scan. Sophos did pick up a few things, but the main "Metropolitan Police" virus is still there.

    So it's Virus 1, Sophos 0 so far... :(

    I'm going to try Kaspersky now....

    here's how I got rid of it / managed to take control of my pc

    1 - Turn off your system & Turn off your router - do not go online.
    2 - turn on your pc but not the router
    3 - after booting you may see messages saying a file cannot be opened / or tabs at the bottom of screen saying web page can not be opened. Close/clear these off the screen
    4 turn your router back on and you should be able to get into google / ie explorer after it connects - from there you should be able to get advice or download some form of malware removal software

    Hope this helps, - think about it - if your offline even though iexplorer has been hijacked it cannot display an online page.

    This worked for me

    Just had this done to me...and I'm fairly bad with computers and fixing them, but this seems to have worked as the guy says flashed up and looked dodgy so immediately turned my computer off by the mains...after a few minutes turned it on again but it popped back up and denied me internet access...turned off by the mains again, then on after a few minutes...ran a system restore to a previous date, then a system diagnostic to look for harmful files..which turned up nothing.
    Checked my Security settings before trying the web again, and my malware settings had been turned off! Surprise surprise! Seems to be working now, don't panic, hopefully my computer is fine now :-) Hope this helps, the bloody scum....

    What are we paying Sophos for? This artical is nearly 2 months old and Sophos still does not offer any protectiion against the attack detailed above.
    Just asking company IT department same question.
    Just been caught 3rd April 2012. Last Sophos update 2nd April 2012.

    • There have been many different variants of this attack.

      If you encounter one that Sophos is not correctly identifying then please submit it to SophosLabs for analysis:

      or contact our tech support team.

    quickest simplest way is to roll back your pc a few days before it got the virus

  15. c pritchard · 1034 days ago

    My son as just had this now he's only 14 and it as come up on his screen with a picture of him that's been taken from his webcam he was in his dressing gown it says its from Cheshire police and he's been illegally downloading or been on child porn I'm most concerned that they have actually got into the laptop webcam and took a picture of him I don't knew what to do or how to get this off

      Have a look here:

      That's a video showing this sort of malware, and how to remove it. In the video you will see a webcam video of me :-)

      If it's any comfort, the crooks *probably* (I can't say better than that) didn't capture the webcam video stream. This sort of malware usually just *displays* it to give you a fright and make you more likely to pay.

      I can't promise that the malware you had didn't steal the video data, but you can consider it unlikely. You still need to remove the malware though - the video above gives you some hints on what to do next.

    Yeah I have the same problem I got some kind of message from spain police that I need to pay 100€ Within 48hours or i will get arrest and when i try to close the window I doesn't allow me says that my computer is blocked damn that scared me.

    I have found this virus on a mac. How do I remove it?

  20. Steve · 201 days ago

    ctrl-Alt-delete- task manager- then delete police programe- by end task.
    Go back into Google. Don not open anything with Google but close Google again with top right hand corner X. Back into Google and all is clear.

    On a Mac you just 'Force Quit' and it will go away. It may come back again later but Force Quit always works

    I had it come up on my ipad and was taken in by the innocent section, as I though a mistake had been made.I became suspious when I read through it again,and found inconstancies .I then repeatedly turned off my ipad and finally it went.what a sham.
