It Security Write For Us – Preserving the integrity of equipment and servers, data, or the corporate website should be a priority for all companies. Today, at Sale Systems, we talk about 10 computer security threats you should avoid and know about. We give you the necessary clues to prevent them.
I recommend you invest some money and time in renewing or installing a new antivirus rather than formatting a computer or server for not doing it on time.
10 threats to your company’s computer security that you should avoid
Did you know that in 2015, at least 430 million new types of malware were registered? And we’re only talking about what Symantec was able to detect, as indicated in its annual Threats to the Internet Security report. The document concludes that companies lost or suffered the theft of around 500 million personal data of their employees.
Cybercrime can have many faces. Industrial espionage, economic blackmail, theft of sensitive information… But all of them entail a cost for those affected. And when it comes to a company, the consequences can translate into significant economic losses.

During the past year, European companies lost 14,000 million euros due to cybercriminals. The figures are chilling!
And not only large companies are subject to these risks to computer security. SMEs have long since begun to suffer all kinds of threats to the safety of their systems, servers, databases, or web pages.
At Sale Systems, we want to inform you about the main risks your business runs and the primary risks your business runs. In the end, we will give some tips to avoid this threat. Let’s go there!
What are the main threats to the computer security of my company?
Let’s see below the types of risks your business runs if you do not take precautionary measures to avoid them.
Most of them are cases of malware, also known as “malicious code” or “malicious software”. But we will also talk about practices that, although they can take advantage of malware, do not stop there and go one step further on the scale of cybercrime.
#1. Computer viruses
They are the most well-known threats to the non-computer-specialized public. It is basically code that an executable program is infected with and spreads by copying itself and infecting other programs or files.
Its consequences and severity vary greatly. Some viruses are only intended to trick the user; others can cause the software to malfunction, damage hardware, or even infect an entire network of users.
Viruses always require human action to become active (for example, the user running unknowingly infected software).
The economic losses can be huge if it damage the company’s software, the operating system, or the equipment and devices.
Keep your Antivirus up to date; you cannot imagine the amount of time and money companies lose having their employees sit idly by for not having invested a little time and money in updating their Antivirus.
#2. worms
What name do they put right? , They are often confused with viruses. However, unlike them, worms do not need human action to activate, copy themselves, and spread through the network. Because that’s what they do! But they behave like that, and I assure you they do not become butterflies.
They can, for example, be copied and sent to each of your contacts through your email or instant messaging service and repeat the operation with the address book of each of your communications. Its propagation capacity grows exponentially.
Worms often crash computers, servers, and the network, hogging resources, consuming bandwidth, and causing severe performance problems.
But they can also be used for even darker purposes, such as creating large networks of zombie computers controlled by bots that can use them to send massive spam, launch cyber-attacks, or download all kinds of malware onto the computer.
Can you imagine how much worms can damage your computer equipment and work network…?
#3. Trojans
Do you remember the Trojan Horse in which the Greeks hid to enter the city of the Trojans and defeat them? Well, malware known as a Trojan horse does the same thing on your computer!
A Trojan Horse or computer Trojan usually enters your computer or device by taking advantage of the download of legitimate software. (Be careful when downloading programs; I recommend that you always download it from the official domain and be cautious with the word free in this context, as it almost always has something hidden).
Hence its name, because the Trojan Horse was supposedly a harmless gift from the Greeks to the Trojans for their bravery in battle.
Is it objective? Open a back door for hackers to control your computer and its software.
Unlike viruses and worms, the Trojan does not cause damage or spread. That is why it goes unnoticed, something essential to fulfill its function.
#4. Adware
Another champion of popularity among users. And it is that the effects of adware do not go unnoticed. Who has not suffered the inconvenience of browsing the Internet wrapped in spam ads and pop-up windows that open uncontrollably in the browser?
Adware is a seemingly harmless type of software compared to any of the above types of malware, but it can drastically slow down the performance of workers who need to surf the Internet to perform their tasks.
Sometimes, adware includes an “antivirus” or other paid registration option that eliminates the problem. This is a hoax perpetrated by the same authors of the adware to be eradicated.
Some time ago, I located a cleaner for this software that we have been using for a long time, which is free. I recommend that you do it with a specialized technician; occasionally, it deletes a service if you touch or activate an option that you should not start. It’s called adwcleaner.
#5. Rootkit
It is software that allows cyber intruders to access computers undetected to steal sensitive information. Rootkits enable privileged access to a user (the hacker) who connects remotely, altering the operating system to hide the maneuver.
It is a real risk for companies and users, who can see their passwords, bank details, etc., stolen.
#6. Keylogger
Although there are also versions that work through devices or hardware complements, we talking about programs that can reach a computer through viruses, Trojans, etc., and that are dedicated to memorizing the keystrokes made by the user. The information is recorded in a file and can be sent online.
As you can imagine, cybercriminals can get hold of passwords, bank details, and other private information.
#7. Ataque Man In The Middle (MITM)
It is an attack in which the hacker intercepts traffic from a sending computer to another receiving computer. That is why it is called Man in the Middle, which in Spanish means “Man in the Middle.”
By becoming an intermediate point through which information passes from its place of origin (an employee’s computer, for example) to a destination location (let’s say it’s the company’s server), the cybercriminal can decrypt the data and Get hold of keys and passwords.
#8. DOS attacks
Having the company website down for some time can mean significant economic losses, especially if it is an online store!
That is the objective of the Denial Of Service (DOS) attacks, or “denial of service.” A computer launches requests to the server where the website is hosted until it saturates it and begins to deny access. The web falls with its corresponding losses in sales, business opportunities, etc.
To stop the attack, simply ban the attacker’s IP. But if the website remains down long enough, the losses have already occurred, and the damage is done.
#9. DDOS attacks
The concept is the same as in the previous threat: massive requests are made until the server is saturated and the web is down. However, the attack we are talking about now is a Distributed Denial Of Service (DDOS), which is more sophisticated than the previous one.
Instead of launching attacks from a single computer, DDOS attacks use many computers to distribute requests to the server. Often, those computers belong to users who do not know what their computers are being used for and have been added to a Zombie network by hackers infecting them with malware.
The problem with this type of attack is that being multi-sourced makes it more difficult to find all the IPs it originates from and, therefore, more difficult to stop.
And these threats are just the tip of the iceberg! They are the most common, but there are many more.
In addition, with the Internet of Things (IoT) revolution, the challenges to device security are expected to increase massively. The increase in devices and consumer goods with access to the Internet will stimulate the development of new threats of all kinds.
Perhaps you fear that you will not sleep peacefully again thinking about the number of computer threats that threaten your company, but do not worry. Not everything is lost!
10. How can I prevent information theft and other computer security problems?
We would like to reassure you by recommending the latest Antivirus on the market… But unfortunately, installing antimalware is not enough!
It is best to implement security protocols to guarantee your company’s computer security and prevent threats, identity theft, data theft, extortion, industrial espionage, and a long list of problems.
