YOUR CORPORATE NETWORK HAS BEEN HACKED email scam in detail

Scammers claim that they have downloaded 120 GB of data and will publish it on their website after 24 hours from sending this email if recipients do not pay $2500 in Bitcoins to the provided wallet. They also claim that not paying a ransom will result in having the whole network locked down.

As a rule, scammers behind such emails do not target anyone in particular. They send the same email to many people hoping that someone will fall for their scam (for example, pay them money, provide personal information).

Email scams in general

Emails of this kind must be ignored. As a rule, the claims that scammers make in their emails are not true. Usually, they seek to extract money or sensitive information. A couple examples of other emails of this type are "Im In Possession Of All Of Your Private Data", "I Am Sorry To Inform You But Your Device Was Hacked".

Emails also can be used to deliver malicious software. Typically, they are disguised as important, urgent letters from legitimate companies, organizations, or other entities.

How do spam campaigns infect computers?

Cybercriminals behind emails used to deliver malware attempt to trick recipients into opening a malicious attachment or a file downloaded through a website link. Recipients infect computers by opening malicious MS Office documents, JavaScript files, PDF documents, or other files.

Malicious MS Office documents do not infect computers unless users enable macros commands (editing or content). MS Office versions released before 2010 infect computers without asking to enable macros commands.

How to avoid installation of malware?

Files and programs should be downloaded from official, pages and through direct links. The operating system and installed programs must be updated and activated with implemented functions, tools provided by their official developers. Files and links in irrelevant emails received from suspicious senders should not be opened.

The operating system should be scanned for threats regularly. It is recommended to run scans using a reputable antivirus or anti-spyware software. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

the network
waiting for our command to lock down your network. Don't try to detect it,
our software is set up
so that if you remove one beacon, the rest will immediately begin to
encrypt your corporate network.
The speed at which our software will have time to block your entire network
is 15 minutes.

!!! WE ARE NOT AFFILIATED WITH ANY COUNTRY'S GOVERNMENT. OUR GOAL IS
COMMERCIAL GAIN !!!

This is an important message. Your company was attacked by cryptolockers
and was successfully hacked.
As a result of the hack 120 GB of information was downloaded from you
network, including accounting documents and
information that constitutes trade secrets. We are working under a new
scheme so as not to represent
inconvenience to the company with which we are dealing with that is why
before we block your computers we offer
solve the issue for a small compensation (which is much less than what will
be after exploitation of your vulnerabilities and
your computers) in the amount of $2500. You have 24 hours to respond to
this message and transfer
funds to this BTC wallet : bc1qtttvn6eyhwshwtdst7tja0eqmgsd8r65phzjz5 . Do
not try to contact the police, it will only make things worse.
We suggest to solve the issue peacefully  without causing you any
inconvenience. In case of non-compliance with our demands,
we will block your computers  and the ransom amount will be x100 times more

we are working on speed and mass.
Do not try to gamble with us. You have 24 hours to respond to our message.
All work is done automatically. We have no centralized servers.
There is no point in negotiating with us. The software automatically checks
the funds into the wallet
and makes a decision based on a neural network. We do not negotiate because
it is not safe.

We work on a double attack scheme. If we do not get a small (ransom of
$2500), then we go to step 2

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.

If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Refresh Autoruns application results

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Search for malware and delete it

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
