WHAT IS EMAIL BOMBARDMENT?

An email bombing is an attack on your inbox that involves sending massive amounts of messages to it. Sometimes these messages are incomprehensible. But more often, they will be confirmation emails for newsletters and subscriptions. Thus, in the latter case, the attacker uses a script to search for forums and newsletters on the internet. Then they sign up for an account with your email address. Each will send you a confirmation email, asking you to confirm your address. Also, this process is repeated on as many unprotected sites as the script can find. The term Email Bombing or Email Bombing; it can also refer to flooding an email server with too many emails. In an attempt to overwhelm the server and disable it. But that's not the goal here; it would be a challenge to cut down on the modern email accounts used. Meanwhile, Google or Microsoft email servers, anyway. So instead of a denial of service (DOS) attack; against the email servers you are using. Also, the flood of messages

TROJANS AND WAYS TO AVOID IT

-

TROJANS

Have you heard of Trojans? You will certainly know the history of the Trojan horse. Like the mythical horse that the Greeks used to enter Troy without anyone noticing, these programs try to enter your computer without raising suspicions, opening a back door for a remote attacker to access the computer.

What is unique about this malware is that it appears to the user as an apparently legitimate and harmless program, but when it is run it gives the attacker remote access to the infected computer.


What is the mission of a Trojan?

The mission of a Trojan is to create a back door that gives an unauthorized attacker access to your computer. And its objective is not very different from other types of malware: stealing confidential and personal information.

The most valuable information is undoubtedly financial information and, for this reason, banks are especially concerned about Trojans that reach computers through emails with attachments. If these files are opened, the malicious code enters the computer and wanders around your house like Pedro, until it manages to steal the online banking passwords stored on that computer.

You may wonder how a Trojan could get the passwords for your accounts. This occurs because Trojans are designed to allow an attacker to access a system remotely and perform different actions without asking for permission. Complicating the situation is the fact that a Trojan can be running on a computer for months without the user noticing anything, but if you follow our recommendations and pay attention to the behavior of your computer, you can prevent the Trojan from taking your computer hostage.

How a Trojan knocks on your door

A Trojan can knock on your door

Through an image or a link on an infected web page.

These Trojans enter our computer and wait in silence until we connect to our online banking.

Other routes of entry are:

Infected devices (Mobile, USB, DVD)

Fraudulent websites (impersonating shops or banks) or legitimate but infected websites.

File sharing programs (P2P)

How do you know if a Trojan is camping on your computer?

Trojans, even if they try to go unnoticed, can leave various signs of their stay on our computer.

If your computer shows any of these symptoms, you may be in the presence of a Trojan:

Screen or pop-up windows with unusual messages. There is no doubt: While there is software spyware installed on your PC, either has been infected by a fake antivirus.

Suspicious behavior of the browser: the Internet browser accesses by itself certain sites that we do not request, it opens and closes windows by itself. It is an unequivocal sign of infection. Many threats drive traffic to some unwanted sites.

Problems with connections. You cannot connect to the internet or the connection is much slower than usual. The malware could be establishing different connection sessions, which will undoubtedly steal our bandwidth and make us browse very slowly or even become an almost impossible task.

Slowness in the Operating System: continuous crashes or the system restarts without the causes being known, programs that unexpectedly begin or terminate their execution.

The antivirus disappears. Another feature of many computer threats is the disabling of the security system you have installed.

How to make life difficult for a Trojan?

To make things far more difficult for a Trojan, follow these recommendations:

·       Install an original antivirus and always keep it updated.

·       Update the applications and operating system.

·       Always be wary of emails from unknown senders.

·       Do not follow links or run attachments if you are not 100% sure of their origin. An application that pretends to be from the bank, but in a software utility generic, such as the one that allows watching videos in Flash format”.

 

How to make your device protected from Trojan

To protect our device from Trojan viruses and to keep our device healthy we should follow these 7 steps to stop Trojan enter your device.

7 steps to follow:

1. Install a quality antivirus

Many people trust the antivirus that come with Windows or Internet Explorer. However, these programs don't represent adequate protection against the growing list of digital threats. It is said to have good antivirus in your device.

2. Install protection against real-time Trojans

Many users think that having an antivirus program that includes protection against Trojans and spyware (spyware) is sufficient. However, going without a full license program can be risky.

3. Keep your antivirus programs updated

New threats to digital security arise every day, which is why updating our protection programs is mandatory. Update them every 3-4 days in a healthy manner

 

4. Perform daily scans.

A virus sometimes escape and affects the device. Scheduling daily scans of the entire hard drive can prove invaluable in detecting, isolating, and removing harmful programs.

5. Disable the “Autorun” or Auto-run

Some viruses operate by adding to external devices such as USB / Flash drives, External Hard Drives or Network Drives. Windows users can disable the auto-run function by following the instructions according to their operating system version.

6. Don't “click” on links in emails or attachments

Sometimes by distraction, users end up "clicking" on attachments they receive by email, even knowing that it is a risky action for their computers. Once this is done, the result may not be seen at the moment, but a virus or Trojan may be acting on the computer's memory, recording and stealing sensitive information.

7. Browse smart

Major browsers have protection mechanisms that notify us when we approach a potentially harmful website. Be careful while sharing your information online. Always check if the page where it seems that we are is indeed trustworthy. Check if the URL is for the organization or company. Some hackers install web pages with an identical design to the original to confuse us and appropriate our information.

TESTING THE ANTIVIRUS THAT YOU USE

Have you ever wondered how antivirus is tested before it is available on the market? The truth is that, despite what you may think at first, these applications pass a series of tests that have the mission, obviously, of verifying their effectiveness. Well, for most IT security vendors these assessments are now out of date. Testing an antivirus before its launch is something that is done regularly. Thus, the AV Tests (name by which the aforementioned tests are known) allow users to choose which antivirus they want to install on their computers, knowing what their main characteristics are and what they protect against. So far everything normal. So what is the problem? Some manufacturers of security solutions have raised their voices against the fact that these tests are “not modernized”. In what sense? Some companies claim that, although the complexity of security applications has grown considerably in recent times, when conducting evaluations they do not test the new technologies w

Boot sector viruses are one of the oldest forms of computer viruses. They infect the boot sector or partition table of a hard drive so that they start the moment the computer is turned on. Here is everything you need to know about them and the threat they pose. It affects system with the hard drive. Mainly, PC-based computers are affected more frequently, although a Mac system may be affected as well. What is boot sector virus? A boot sector virus is not a specific virus, it is a particular way that viruses can affect your computer. A boot sector is a physical sector on your hard drive that is required to initiate the boot process and load your operating system. By placing a virus here, it means that the virus is activated every time you start your computer, even before your operating system starts to start. Often times, you won't even realize it's happening, making the threat even worse. How does the boot sector virus work? Each boot sector virus works differentl
