Tech support scams persist with increasingly crafty techniques

Millions of users continue to encounter technical support scams. Data from Windows Defender SmartScreen (which is used by both Microsoft Edge and Internet Explorer to block malicious sites) and Windows Defender Antivirus show that some three million users are subjected to these threats every month.

In addition to being rampant, technical support scams continue to evolve, employing more and more complex social engineering tactics that can increase panic and create a false sense of legitimacy or urgency in an effort to get more victims.

Given the sheer volume of tech support scams and the pace at which they evolve, here at Microsoft we take a holistic approach to this problem. We monitor the threat landscape for patterns and variations in threat behavior. Using intelligence from sensors, we employ machine learning models to deliver cloud-based protection against the latest tech support scams, whether they take the form of web pages with malicious scripts or Trojans that run on computers.

In 2016, the threat of support scam was most felt in the United States, which saw 58% of encounters. United Kingdom, Canada, and Australia follow, with 13%, 11%, and 8% of encounters, respectively. Notably, significant encounters were also registered in France and Spain, where we saw localized technical support scam attacks.

(Note: This blog post is the third in the 2016 threat landscape review series. It follows the review of exploit kits and ransomware. The series looks at how major areas in the threat landscape transformed over the past year.)

The evolution of technical support scam malware

Technical support scams are built on the deception that your computer is somehow broken, and you need to contact technical support to fix it. You may then be asked to pay for support. In some cases, the tech support agent may ask you to install other software or malware disguised as support tools on your computer, bringing in more threats that can cause even more damage.

You may come across these threats while browsing dubious websites, most notably those that host illegal copies of media and software, crack applications, or malware. Links or ads on these sites may lead you to tech support scam websites, which display pages that are designed to look like error messages and serve pop-up messages indicating fictitious errors. Some tech support scam threats take the form of executable programs like other malware.

Although tech support scams have been around for many years, in 2016 we saw the threat evolve by  integrating more scare tactics. At the beginning of the year, the landscape was dominated by threat families with simple techniques and social engineering lures. However, more evolved threat families have since taken over.

FakeCall and FakeBSOD: The early types that used one pop-up window and simple messages

Tech support scams are known for their use of pop-up windows to advance their pretense. While most of the scams today abuse pop-up windows to the point of locking the browser, the earlier types relied on just pop-up windows and effective social engineering lures.

FakeCall is a family of malicious scripts hosted in tech support scam sites. It may use messages about virus infection or suspicious activities on your computer. The first sign you have been led to a FakeCall tech support scam site is a pop-up message that tries to create an impression that it’s a system pop-up and usually describes a fake problem and contains instruction to contact fake technical support.


Figure 3. A sample pop-up message from FakeCall

If you click OK, the website loads a page giving more details about the supposed problem, and more instructions to call the technical support number. It may spoof security products and list malware that have purportedly been found on your computer. The goal is to convince you to call the support number.

On the other hand, FakeBSOD is a very similar threat but instead pretends to be a system error, like Blue Screen of Death (BSOD), where it got its name.


Figure 5. Sample FakeBSOD site that pretends to look like system errors, such as BSOD, and asks to call 18443307888

FakeBSOD sites usually force the browser to go on full-screen mode to simulate the BSOD experience. Just like FakeCall, it also has a pop-up message detailing the fake problem and a number to call fake technical support.

Both FakeCall and FakeBSOD heavily rely on social engineering lures to get you to take action, and don’t have much in terms of technical complexity. Simply closing the browser will work in most cases.

TechBrolo: Support scam malware on steroids

TechBrolo takes on characteristics of both FakeCall and FakeBSOD, but integrates technical enhancements that not only makes the pretense more believable but can also adversely affect your overall computing experience.

For instance, TechBrolo employs the dialogue loop technique. When you visit the TechBrolo site, you get a pop-up message that won’t go away, no matter how many times you click OK. This method effectively locks your browser; you must manually terminate the process via Task Manager in order to close your browser.


Figure 6. Sample TechBrolo site with dialogue loop and fake support number 18662190211; some tech support scam sites use other phone numbers like 8774747124, 1846514111, 11800941045, 18448096665, 18882414464, 18442413997, 448000903858, 18447672832, 8008021491, 18442839572, 8000465712, 0345404950, 0345791995, 0345404951, 34932200207, 33186265239, 34932200211, 34932200207, 5541708902, 18442090189, 18442432457, 18886054764

Most variants of TechBrolo also play an audio describing the problem, adding a sense of urgency. For example, one recent variant mimics Windows Defender Antivirus, and when the website loads, it plays an audio with the following message:

“Critical alert from Microsoft. Your computer has alerted us that it is infected with a virus and spyware. This virus is sending your credit card details, Facebook login, and personal emails to hackers remotely. Please call us immediately at the toll-free number listed, so that our support engineers can walk you through the removal process over the phone. If you close this page before calling us, we will be forced to disable your computer to prevent further damage to our network. Error #268D3.”  It is important to note that Windows Defender Antivirus does not act this way.


Figure 7. Sample TechBrolo site that spoofs Windows Defender Antivirus, plays an audio message, and uses fake support number 0754059588; some tech support scam sites use other phone numbers like 1800874943, 0481681015, 1800954279, 08000465706, 33186265253, 0186265264, 18772114524, 18448161643, 78481267, 1800875382, 1800958212, 1800958217, 08000465254, 08000465706, 08000465024, 8552061675, 8552490763, 33186265266, 611800941045

Recently, we also spotted a TechBrolo variant that uses website elements to spoof the Microsoft support site and fake the pop-up dialogue box. It does this by loading a page that looks like a browser and then going to full screen. If you are not too paying attention, you might think Microsoft is giving you a warning. Microsoft does not deliver warning messages like this via the browser.

Non-English support scam websites

Consistent with our findings that some of the countries most affected by tech support scam are non-English speaking countries (see Figure 1), we have seen some localized tech support scam malware.

These sites employ a combination of the techniques discussed in this blog, only presented in non-English websites, images, or pop-up messages.

Cusax, Hicurdismos, and Monitnev: Support scam Trojans

Apart from scripts hosted on websites, we have also seen tech support scam malware in the form of executable files. They may be installed on your computer by other malware or downloaded from drive-by sites.

These malware have the same goal as their script counterparts: to get you to call the technical support number. However, the difference is that their malicious behaviors are not limited to the browser.

For instance, Cusax is a tech support scam malware that makes system changes, including registry modifications that ensure it runs every time your computer starts. It then forces a reboot, further reinforcing the scam that there is a problem with your computer.

As soon as your computer boots, it opens a window that asks for your Windows activation key as well as the technical support number.


Figure 13. Cusax uses the lure that you need to enter your activation key and asks to call the number 18772563313

Hicurdismos, on the other hand, displays an image that looks like the BSOD. However, this fake BSOD screen has instructions to call a technical support number, something that the real error doesn’t have.

In order to further its pretense, Hicurdismos hides the mouse cursor, disables Task Manager, and makes sure the fake BSOD image occupies the entire screen and is always on top of other windows.


Figure 14. The fake BSOD screen displayed by Hicurdismos contains the number 18004184202

More recently, Monitnev was discovered to monitor event logs. It then displays fake error notifications every time an application crashes. This can appear more convincing because the pop-up messages are timed with legitimate computing behavior.

Cusax, Hicurdismos, Monitnev and other tech support scam malware can be more complex than scripts. Because they make system changes, they can inflict more damage and can be trickier to remove. However, we’re seeing significantly fewer of these types of tech support scam threats because they are more difficult to distribute than their script counterparts. Despite that, they pose threats that you need protection from.

Protection against tech support scams

Tech support scams take different forms and are known to take on more characteristics over time. Get the protection against the latest tech support scams by upgrading to Windows 10. The Windows 10 Creators Update brings in additional security features and will start rolling out on April 11, 2017. Keeping your computers up-to-date gives you the benefits of the latest features and proactive mitigation from Microsoft.

A majority of these threats, like TechBrolo, FakeCall, and FakeBSOD, are scripts hosted on websites where you are led to by malicious ads on dubious sites. To avoid tech support scam websites, use Microsoft Edge. Enable Windows Defender SmartScreen (also used by Internet Explorer) to block known malicious websites, such as tech support scam websites.


Figure 15. Microsoft Smart Screen blocks techs support scam websites

In addition, Microsoft Edge provides a way to close dialogue loops, which are used by support scam sites to keep on delivering pop-ups even after you close them. At the bottom of pop-up dialogue messages, you have an option to tick the checkbox Don’t let this page create more messages, which will stop the recurring messages.


Figure 16. Dialogue loop protection for Microsoft Edge

Enable Windows Defender Antivirus to remove tech support scam Trojans, such as Cusax and Hicurdismos. Windows Defender AV uses cloud-based protection, which helps make sure you are protected from the latest threats.

Tech support scams employ varying social engineering techniques to get you to call the support hotline. Do not call the number in pop-up messages. Microsoft’s error and warning messages never include a phone number.

Some scammers can also contact you directly and claim to be from Microsoft. Remember, Microsoft will never proactively reach out to you to provide unsolicited PC or technical support. Any communication we have with you must be initiated by you. Reach out directly to one of our technical support experts at the Microsoft Answer Desk.

    I think my Windows 10 account has been hijacked. What do I do?

      talk to an IT specialist you trust in person

      1. Jack says:

        Same **** happen to me
        Bethany scammed me for $499 & asking for more like begging…

        Beware their number is – 1 844 864 9028.. Located in California & Asian countries…..***

  2. Dawn Iler says:

    Is a number that called my home. If called back it is a non working number. please check it for the fake calls. I have had one before. “Paul” from windows who said my pc was sending info that it was infected. It certainly was and I lost that computer. I personally have thought it was you as I had emailed the disability desk the day before the call with a complaint/question. I felt forced to upgrade when I couldn’t afford it nor did I want to. I was forced into a new/used pc and I thought I needed to upgrade even though I was very happy with the OS I was running. But you blocked my internet and email. I did have virus protection running but was hacked. everything was hacked, email, printer all files, Everything. I did find it on my pc and right now I don’t recall what I read in it that kinda confirmed my suspicions of it being Microsoft. I can get you the photos of what I found if you want? If I voiced my thoughts about not wanting to change or purchase a new pc something would go wrong with my pc. Almost immediately. Coincident’s do happen I suppose. And another thing, why don’t spell checker give me the correct spelling of coincident?S If it is misspelled already how am I to know which of your suggestions is right when it gives three or more spellings? The plural option was not offered just now.
    Back to Win 10, I hate it. Switching was the worst mistake in my entire life. I can not hi lite and print the hi lited part, I can’t blow up or shrink things to the size I want. I find 10 to be irritating and prevents me from doing things I used to be able to do. I LOST YEARS & YEARS OF EMAILS! IMPORTANT SAVED EMAILS THAT WERE JUST GONE. POOF GONE. I STILL NEED SOME OF THOSE EMAILS. INFO I CAN’T FIND IS IN THEM…. OK I AM DONE

    Hey MMPC.

    I think Office 2010 Pro Plus is broken on Win10 Pro 1703.
    I set Word to Autorecover every 10 mins and to keep last autosave when file isnt saved.
    Theres no asd file being saved! There are folders named like the files’ names but theyre empty!
    The files being worked on are on a usb storage.
    I have Officetab free edition 9.51 addin.

    All was well with Win10 version 1607 since there are asd files in Recycle bin; asd files are created and they were moved to Recycle bin after 4 (?) days I think.

  4. adwbust says:

    Pls help MMPC. Pls tell the team responsible that Win10 version 1703 update broke Autorecover of Office 2010 Pro Plus x86. I have Win10 Pro x64.

  5. adwbust says:

    Settings, Acer care center and Edge crash after upgrade from 1607 to 1703.

    1703 broke Autorecover of Office 2010. No Asd files are created.

    On one laptop, WD security center always shows 0 files scanned.

    Health report doesnt work on one laptop and sometimes works on another.

    Onedrive pops up when you go to Word 2010 > File > Recents > Recover unsaved.

    File explorer icon pinned in taskbar looks active when you get Low battey pop up (< 10%). Left clicking icon wont open file explorer.

    Bluetooth on one laptop doesnt work since 1607. Probably drivers. But no new drivers available.

    After upgrade to 1703, wallpaper changed to default!

    Check box for "Send info to MS on how I type and write" removed in 1703. Full diagnostic should have tree view so we can uncheck items like typing/writing! MS did this so we have no full choice and control over what's sent!

    But of course 1703 brought positives too. Windows store check for updates, download updates and install updates are more faster and smoother. Same with Windows updates. Perhaps since not much on 1703 yet?

    Please relay to team(s) responsible.

  6. adwbust says:

    WD security center lacks Quarantine, Allowed and Detection present in WD on 1607!

    Will WD on 1703 have ATP for Win10 Home/Pro and PUA detections?

  7. adwbust says:

    I’m disappointed you just remotely turned off MSE (non-functional) on Vista on April 12. You couldve have just continued providing engine/signature updates until support for version 4 branch is discontinued.

    Oh well, I just switched to another AV. Life continues.

  8. adwbust says:

    Let apps run in background enabled. WD security center enabled. Why isnt WD updating on its own when wifi is set as metered then? Background apps keep themselves up to date right?

    April 12 Patch day for Win10 version 1703 still didnt fix broken Autorecover of Office 2010 (tested Word)! Word doesnt create Asd files as intented! Set it to autorecover every 1 min but no Asd files!

      @adwbust — Thank you so much for providing valuable feedback. We have forwarded your concerns to the right channels.

      For future feedback about any Microsoft product or service, please consider using the Feedback Hub.

      Using the hub helps ensure that your concerns are forwarded to the correct teams and are tracked properly.

      1. adwbust says:

        Thank you! If I log in on Feedback hub using my MS account, will I be auto logged in to (1) Settings > Accounts and (2) Windows apps on PC? I will report on Feedback hub if log in will only work in-app not OS-wide. I dont want stuff on PC synced to my account and vice-versa.

        I tried on Office 2016 and Word still creates Asd files. Probably an Office 2010 only issue or caused by Office tabs free 9.51 addin, a recent Office 2010 patch or Win10 version 1703 upgrade. Last auto-deleted Asd file in Recycle bin was from March.

        WD security center lacks Scheduled scans, Quarantine, Allowed/Detected logs, Recommended actions for detections, ATP and PUA opt in.

      2. adwbust says:

        When will Office 2016 get native tabbed window support? Adobe Reader DC already added it. Pls tell Office 2016 developers to add it in next update.

  9. adwbust says:

    The sample form still times out! 🙁 I tried to submit a 3,715,193 bytes 7z archive. My upload speed is only 800 kbps. 🙁 I have no access to fiber dsl yet. I have no issue with Avira’s or Bitdefender’s sample form. I think the implementation is at fault. After I browse for sample, start to upload it. Currently, your site will only upload sample when I click Submit button. Not everyone has fast upload speed to keep up with your site’s demands/expectations. 🙁

    I got this:

    The server timed out while waiting for the browser’s request.

    I removed MSE on Vista since it was deactivated. But I re-enabled WD. So far, WD doesnt seem to detect Software bundlers and Monitor tools (keylogger, spyware) caught by MSE. Those are grey threats so why doesnt WD catch them too?

    1. adwbust says:

      Hacktools arent detected by WD on Vista as well. :/

    You need to go back to school and go into big time debt and learn something. Take Windows 8, 8.1 and 10 with you.

  12. Sunny Holmes says:

    This happened to me today. My computer was locked and a number was given to call. It was 844-976-8875. I called and went through their process as it scared me… Showed me all the downloaded hack files..Don’t see this exact number on the list above..

  13. jeff says:

    I received one of these scams to day and they are going to call back tomorrow to see if I can pay for it

  14. Alex says:

    We received a message claiming we had to call Microsoft immediately at 1-844-392-7021. When called, an “East indian accent” individual mentioned they had to get into our computer to fix the problem and requested permission to do so. We indicated we will not allow this and terminated the call. The phone is listed among those used for scams.

  15. Zoe says:

    This has happened to me I turned pc off now I can’t log back on. Any advice plz?

  16. Paul Beatt says:

    you can add 1843 577 2056 to the list. The scammer wanted to show me where the problem was by logging onto my computer and pulling up windows 10 by holding down the Crtl, Fn and windows key. I hung up and he immediately called back and told me that I would see that all of my drivers would be blocked if I did not do as I was told. I will not repeat what I told him to do with his suggestion and then hung up.

  17. Alan James says:

    I believe I was scammed today by an outfit calling themselves Assistance Online Support. This was in response to a warning that appeared on my browser saying that there was suspicious pornographic spyware and had a contact support number. The so called error was 0x80072ee7 which they said was from an external intrusion trying to access my personal details. The names they used are: Eric Lundy, Jason Cox, Toby, and Rachael- all with Indian accents. Rachael told me she was in California. Eric asked me for my debit card details which I naively gave him but fortunately my bank alerted me via text that they put a hold on the transaction. Should it be a scam it is well orchestrated as they even send invoices and gave work id numbers. The support number they provided was 0064 800 005 466 or 0800 005 466. The one called Rachael said she did something to my computers IP Address. I note as I read on my Network settings under connectivity (IPv4/IPv6) connected to the internet/Connected to unknown network

  18. Tigerzateal Irizarry says:

  19. Rob Thorn says:

  20. Rob Thorn says:

    I just told this fake to stop calling me, and that I will not give any information The caller then said I don’t need you to give me any information, I can hack into you bank account any time I want.

    Today, I googled “Lowes” to find the store website. When I clicked on the results from Google; Ad Lowes it redirected to hxxp://microsoft1115supportnumber[.]com/main/index[.]html with a scam asking to contact 1-844-699-8351.
    A voice recorded and a fake Microsoft page.
    Don’t fall for it.

    1-800-615-9085 is not real. ~ Do NOT call number. ~ to turn IT Off.. [1) open windows Task Manager – [2) view the “application” tab – [3) mouse on the browser (ie = Internet explorer) – [4) RIGHT click & mouse to “End Task” – [5) DO IT! …end the motherFawker.

  28. Gary Chambers says:

    Just had laptop lockup with an apparent Microsoft webpage and a superimposed message in black box: “Microsoft System Security Alert. Something went wrong with your Windows…”. There was also a a repeating audio (female American voice) warning to call “our” support. I called the number on the underlying webpages was “1-844-311-9589” to see who would be on the other end. An asian female voice answered “Enigma Technical Support” and I hung up to do research on my wife’s Mac; going to the Microsoft web site. I was called back 3 times quickly by “Enigma’s Tech So” at 1-844-305-6555, but they never left a message. I read the site’s description of the technical support scam and found their number listed above in column 3 line 18. Not knowing anything else to do, I did a hard shutdown and then restarted after a minute. A quick scan with a freshly updated Total Defense Anti-Virus was clean.

  29. Willie E Cummings says:

    I received calls from 877-650-4751, 877-335-4612, 844-821-0482 by people using the name Microsoft

    I clicked on a link about an old murder being solved on the MSN home page yesterday? How does that happen ?

  32. Dan McDonald says:

    Are you having someone from California contact me telling me I need to fix my Microsoft account. I’m Worried that this is a scam to get into my computer. If this is not the case, Please let me know. The number calling me is 513-225-5069.
    Thank you

    1. John M Rigby says:

      My wife’s computer has been blocked by a virus (Zeus) and a box instructing us to call Microsoft. I suspect this is a scam but how do I unlock her computer? Restarting it doesn’t help.

  33. Steven Chambers says:

    My computer has been hijacked by an apparently fake Microsoft support company, S M Tech Solutions. The number being used by the “agent” is 909-939-3661. They are demanding payment in iTunes cards to evade taxes in India. They are threatening lawsuits and extraction of funds if I don’t pay. I have already paid $4400 in iTunes cards and will not pay the $9000 they are trying to extort now. I have closed out one credit card and alerted the other. My cell number is 503-580-0570.

  34. Marzig says:

    I have a number for you to add to the scammer list 459-750-7880 caller id was Invalid Number ; was called today 6/16/2017. I was also called yesterday but I am unsure as to which numbers to give you because we get stupid sales calls from other companies wanting to put solar panels and other junk in…and they have goofy numbers too. This really is too much. I think the uptick in calls might be due to kids getting out of school for summer, good opportunity to get the kids to let them have access to our computers. A public announcement would be cool, not everybody seems to be up on the Scammer tactics. Thanks

  35. ric says:

    yes, crafty they’re
    an 8886356193 just got off saying we’re “Online Service Technologies” based in Los Angeles, CA
    when I repeated his name back to him and explaied that his story sounded odd cause there’s no such business listing he replied
    “well here let me give you our website address,” and then disconnected

  36. Robin says:

    Rcvd call from 202-765-1235, kathy (middle east accent) id# RFS3625. Said she was from MS, they were rcving msgs from my comp under attack. Wanted me to give her permission to control comp. I needed to hurry, may be able to save. I asked her for MS # to verify, gave me HER # & id info. I said ok, please hold. I went online to get MS # & called on cell phone. Told to hang up by what i thought MS official support. Come to find out MS Official Support was an ad, a PARTNER of MS, not MS (, again middle east accent, i had to ask him 3 times point blank, ‘are you MS or a partner?’ and how much would this cost me? Said i didnt need to worry about that right now. Kept telling me to i needed to do this, that. Kept talking over me. I finally had to yell and told him to answer me, finally admitted partner. I hung up again.
    What i don’t understand is why MS is so hard to find to get info in emergency situations like this. Last time i had an emergency i had right # but could not get an answer and that time comp caught in loop. Finally got out of loop, no clue how. Finally got MS online after several tries. Sorta got ‘oh yes that happens, we will make sure ok. We did check together, but wow, after the fact.
    This time, she was still on the phone line, partner told me to hang up, wasnt really interested in her or info she gave. Thats what kind of clued me in not MS. Really felt let down ny MS both times.

  37. John O'Connell says:

    I had a call from someone who said they were from Windows Help desk and that my computer had shown signs of attempted hacking. They convinced me that they were genuine by giving me a unique number of my PC. I paid £299.00 to a company called www[.]Thaipay[.]com and gave them access to my computer where they deleted so called threats. I have since had call form them saying my computer was still at risk and they want to get into it in a session with me. I wonder if you can tell me if they are genuine and attached to you

  38. Ross A. Morgan says:

    I recently received a call from 1-800-291-4814, telling me that my Microsoft license is due to
    Expire and I should call back to renew it. I ignored it because I have never had a Microsoft product or license. Therefore, I suspected it to be fishing scam.

  45. Edward Murphy says:

    The Phone Number I was given to contact (I am in the UK) was 0208 0683410 when I received an alert message informing me my computer had been compromised. It informed me to contact the number given immediately and not to try and close down the computer otherwise they would have to delete my account (or something similar). When I tried to close my web page it message kept popping back up and would not let the computer close, so I closed took the battery out to close it. I then re-opened and logged in with no problem and ran Windows Defender full scan and it detected this virus which I then deleted. I then checked it out in Defender and now send my reply to what I experienced.

  46. Melanie Snyder says:

    I got one of these today also. The number I was told to call was 1800-890-8720. He told me I had to pay $199 to get my computer fixed of the virus. I told him I wasn’t paying money to a system that had a virus, he laughed at me. And they also have caller id, cause they called me back when I hung up on them. I am now running a McAfee virus scan.
