Hidden dangers of Trojan Horse

The term Trojan horse often thrills those who know about cybersecurity, but to the general public, it can seem as mysterious as a science fiction film. In reality, a Trojan Horse, or “Trojan” in English, is a category of malicious software (or malware) that disguises itself as a legitimate program to deceive the user and infect their systems.

Be careful, Trojan Horses don’t just throw unwanted alerts on your screen. Their goal is far more sinister. These malware can give cybercriminals access to your computer, allowing theft of personal data, spying on online activities, and even full control of your device.

THE hidden dangers There are multiple Trojan Horses:

  • Theft of sensitive data : usernames, passwords, credit card numbers.
  • Spying : Hackers can monitor your online activities, including your private conversations.
  • Remote access : Attackers can take full control of your device, installing other malware or using your machine for additional attacks.
  • Illegal use of resources : your computer can be used as a zombie in a criminal network to launch DDoS (Distributed Denial of Service) attacks.

To protect yourself from these threats, some best practices are necessary:

  • Only download software from trusted sources and always check the reviews and reputation of the site.
  • Update regularly your operating system, your applications, and your antiviruses.
  • Analyze your system regularly to detect any suspicious activity using anti-malware software.
  • Beware of attachments and links in emails, especially if they come from unknown senders.

By adopting these preventive measures, you can significantly reduce the risk of falling victim to a Trojan Horse, and thus protect your data and your privacy.

Concealment method

The term Trojan horse, often used in the field of cyber security, finds its origin in Greek mythology. However, its modern implications are far more alarming. A Trojan horse is a type of malware that hides behind a seemingly legitimate program or file. Once installed on your device, it opens the door to potential dangers.

History and evolution

A Trojan horse is much more than a mythological reference. In cyber security, this term refers to a malicious program that hides under harmless appearances to infiltrate a computer system. This method is extremely sophisticated and pernicious.

Its origin dates back to ancient Greece, when the Greeks used a ploy to enter the city of Troy with a wooden horse full of soldiers. Today, this same principle is used by cybercriminals to gain access to your sensitive data.

The first computer Trojan, called “Creeper”, saw the light of day in the 1970s. Since then, these programs have continued to evolve, each time becoming more difficult to detect.

THE modern Trojans can be presented in different forms:

  • Attachments in a legitimate email
  • Free apps downloaded from unverified sources
  • Clickable links on websites known for poor security

It is crucial to recognize the signs of a possible Trojan infection. This includes sudden slowdown of your system, incessant pop-ups and unusual behavior of your computer. If you notice these symptoms, it is recommended to immediately run a full scan with a antivirus software up to date.

To protect yourself against these threats, it is essential to follow a few good practices :

  • Never open attachments from a suspicious email
  • Download programs only from trusted sources
  • Regularly update your security software
  • Be vigilant against clickable hypertext links

Adopting a proactive and informed attitude can make all the difference in avoiding falling into the trap of Trojan horses. Although these threats are becoming more sophisticated, by remaining alert and taking appropriate measures, you can significantly reduce the risk of infection.

Origin of the expression

THE Trojan horse is a frequently used term in cybersecurity, but few people fully understand what it entails. This article reveals the truth behind this insidious threat.

Contrary to what one might think, a Trojan Horse is not a virus in itself. This is a type of malware which hides under a legitimate appearance, thereby deceiving the user to settle on their computer Or network. Once inside, it can open the door to other attacks, steal sensitive data, or even take control of the system.

The Trojan Horse takes its name from Greek mythology, more specifically from the famous story where the Greeks gave a large wooden horse to the Trojans. Once brought inside the city walls, Greek soldiers hidden inside the horse came out and opened the gates to the Greek armies, leading to the fall of Troy. In the same way, the malware hides inside a seemingly harmless program, but once installed, it releases dangerous components.

Since its creation, the Trojan Horse has evolved a lot. Originally, these malware were relatively basic, offering only backdoors for attackers. Today, Trojans can be extremely sophisticated, including keylogging (keystroke recording), screenshots, and even full remote access.

Users should remain vigilant and take certain precautions to protect themselves against these threats. Here are some practical tips:

  • Never download software or open email attachments from untrusted sources.
  • Use a anti-virus and one firewall quality to detect and block threats.
  • Keep your software and operating systems up to date in order to benefit from the latest security updates.

By following these tips, you can significantly reduce the risk of falling victim to a Trojan horse.

This concept has been adapted in the computer world to refer to a program that appears benign, but which harbors a malicious component.

The first ones Computer Trojans began appearing in the 1980s and 1990s. They were often distributed via floppy disks or downloaded .exe files. Their goal was to steal personal information or disrupt computer systems.

As technologies have evolved, Trojan Horses have also evolved. Cybercriminals today use more sophisticated techniques to distribute this malware. Here are some modern adaptations:

  • Phishing emails : Emails that appear to come from trusted sources but contain infected attachments or links.
  • Stealth downloads : Compromised websites that install malware without user intervention.
