What is a Trojan Horse?
Trojan horses are a kind of malicious software that looks like a normal program or file. They trick users into installing them on their devices. Like the ancient Greek myth, these programs hide their true dangerous nature and can cause big problems once they are opened.
Technically, Trojans are not viruses but a kind of malware. They can do many bad things like delete data, censor it, change it, copy it, and mess with computers or networks.
Understanding Trojan Horses
The story of the Trojan horse comes from Virgil’s Aeneid and Homer’s Odyssey. The invaders of Troy used a horse that looked like a gift to get into the city. Digital Trojan horses work the same way, sneaking into computer security systems by pretending to be normal programs.
Trojans can’t spread on their own like viruses do. They need users to install them by opening bad emails, downloading harmful files, or visiting dangerous websites. Once in, they can steal data, download more malware, or let hackers control the device.
“Trojans are a popular tool among cybercriminals, with 10 different types identified, such as Exploit Trojan, Downloader Trojan, Ransom Trojan, and Banking Trojan.”
| Trojan Type | Description |
|---|---|
| Backdoor Trojans | Allow hackers remote access to computers, often used for uploading, downloading, or executing files at will. |
| Exploit Trojans | Inject code to exploit weaknesses in software. |
| Rootkit Trojans | Aim to hide malware on systems for maximum damage. |
| Banker Trojans | Target personal information related to banking and online transactions. |
| DDoS Trojans | Are programmed to execute DDoS attacks flooding networks with requests. |
| Downloader Trojans | Are designed to download additional malware onto devices. |
It’s important to stay up to date with the latest Trojan horse threats and cybersecurity tips. By knowing about these dangers, users can protect their devices and data from Trojan attacks.
How Trojan Horses Work
Trojans don’t spread on their own like viruses do. They need users to install them by opening infected emails, downloading bad files, or visiting dangerous websites. Once in, they can steal data, download more malware, or give hackers control of your device.
They trick people by looking like normal files. When someone clicks or installs them, the Trojan installs more malware and runs every time the device turns on. This can turn a device into a zombie that hackers control without you knowing.
| Trojan Type | Description |
|---|---|
| Backdoor Trojans | These Trojans create a virtual “backdoor” to a computer, providing hackers remote access. |
| DDoS Trojans | These Trojans flood networks with traffic to bring them down, causing distributed denial-of-service (DDoS) attacks. |
| Downloader Trojans | These Trojans infect computers to download and install new malicious software. |
| Fake AV Trojans | These Trojans impersonate antivirus software, extorting money from users. |
| Game-thief Trojans | These Trojans target online gamers to steal account information. |
| Infostealer Trojans | These Trojans collect data stored on infected computers. |
| Malfinder Trojans | These Trojans aim to steal email addresses from specific devices. |
| Ransom Trojans | These Trojans demand a financial ransom to fix computer damage caused. |
| Remote Access Trojans | These Trojans allow complete control over a computer remotely. |
Trojans often look like email attachments from trusted sources. They can also come from websites with weak security. Keeping your system updated is key to avoiding these threats.
Common Types of Trojan Horses
Trojan horses are a big threat in the world of malware. They often look like normal software to trick users into installing them. There are many kinds of Trojan horses, but some are especially dangerous.
Backdoor Trojans
Backdoor Trojans let hackers control an infected device from afar. They can upload, download, and run files without the user knowing. This makes the system’s security and privacy at risk.
