As mobile devices become increasingly popular, they are also becoming more vulnerable to malware attacks. Malware is any type of software that is designed to harm, steal, or damage data on a device. Many different types of malware can infect mobile devices, and understanding what they are and how they work is crucial to keeping your device and data safe.
In this article, we’ll discuss the 20 most common types of malware that can infect your mobile device.
1. Adware
Adware is a type of malware that displays unwanted advertisements on a device. These ads can be intrusive and may slow down the device or even cause it to crash. Adware is often bundled with legitimate apps or distributed through third-party app stores.
2. Spyware
Spyware is a type of malware that is designed to spy on a user’s activities and collect sensitive information, such as passwords or financial data. Spyware can be difficult to detect and can be distributed through phishing emails, text messages, or third-party app stores.
3. Trojan
A Trojan is a type of malware that disguises itself as a legitimate app or software but is designed to steal sensitive information, install additional malware, or take control of the device. Trojans are often distributed through phishing emails, text messages, or third-party app stores.
4. Ransomware
Ransomware is a type of malware that encrypts the data on a device and demands payment in exchange for the decryption key. Ransomware can be distributed through phishing emails, text messages, or malicious websites.
5. Rootkit
A rootkit is a type of malware designed to gain root access to a device, giving the attacker complete control over the device. Rootkits can be difficult to detect and can be distributed through third-party app stores or malicious websites.
6. Fileless malware
Fileless malware is a type of malware that does not rely on traditional files to infect a device. Instead, it resides in the device’s RAM, making it difficult to detect and remove. Once installed, fileless malware can perform a range of malicious activities, such as stealing data or controlling the device remotely.
7. Backdoor
Backdoor malware is designed to create a hidden entry point into a device, giving attackers remote access to the device without the user’s knowledge. Once installed, backdoor malware can be used to steal sensitive data, launch attacks on other devices, or even turn the infected device into a bot for use in a larger attack.
8. Botnet
A botnet is a network of infected devices that are controlled by a central server. Botnets can be used for various malicious purposes, such as launching DDoS attacks or sending spam emails. Users may not be aware that their device is part of a botnet, as the malware operates in the background without the user’s knowledge.
9. Keylogger
A keylogger is a type of malware that records every keystroke made on the device, including passwords, credit card numbers, and other sensitive information. Keyloggers can be used for identity theft, financial fraud, or other malicious purposes.
10. Man-in-the-middle (MITM) Attack
A MITM attack occurs when a cybercriminal intercepts communications between two devices, allowing them to eavesdrop on the conversation or steal sensitive information. MitM attacks can be conducted through a variety of means, such as Wi-Fi network spoofing or malware that intercepts data transmissions.
11. Scarewareccess Trojan (RAT)
A RAT is a type of malware that allows attackers to take remote control of a device, giving them access to the device’s files, camera, microphone, and other functions. RATs can be used for a range of malicious activities, such as stealing data or using the device to launch attacks on other systems.
12. Scareware
Scareware is a type of malware that tricks users into believing their device is infected with a virus or other type of malware. Scareware often displays pop-up windows or alerts that warn the user of a supposed infection and then encourage them to download and install fake antivirus software that is malware.
13. Screen locker
A screen locker is a type of malware that locks the device’s screen, preventing the user from accessing any apps or data. Screen locker malware is often used for extortion, as attackers may demand payment in exchange for unlocking the device.
14. SMS Worm
SMS worms are spread through text messages and can infect a device when the user clicks on a link or installs a malicious app. Once installed, the SMS worm can send itself to the user’s contacts, rapidly spreading the malware.
15. Zero-day exploit
A zero-day exploit is a type of malware that takes advantage of a vulnerability in the device’s software that is not yet known to the software vendor. Zero-day exploits can be highly effective, as they can bypass existing security measures and remain undetected until the vulnerability is discovered and patched.
16. Banking malware
Banking malware is often spread through infected apps or links in phishing emails. Once installed, the malware can intercept the user’s banking transactions, steal login credentials, or access sensitive financial information. Users should be cautious when entering their banking information on their mobile devices and should only use trusted apps or websites.
17. SMS Trojan:
SMS Trojans can be spread through infected apps or links in phishing emails. Once installed, the Trojan can send premium SMS messages without the user’s knowledge, resulting in unexpected charges on the user’s phone bill. Users should be cautious when clicking on links in text messages and should only install apps from trusted sources.
18. Fake Apps
Fake apps can be difficult to detect, as they often look like legitimate apps. They can be downloaded from third-party app stores or malicious websites. Once installed, the fake app can collect sensitive information, such as the user’s login credentials or location data.
19. Cryptojacking
Cryptojacking is a relatively new form of malware that has become more prevalent in recent years. It can be spread through infected apps or links in phishing emails. Once installed, the malware uses the device’s resources to mine cryptocurrency, slowing down the device’s performance and draining the battery.
20. Malvertising
Malvertising is often spread through online ads. Malicious ads can be placed on legitimate websites, and when the user clicks on the ad, the malware is downloaded onto the device. Users should be cautious when clicking on online ads and should only visit trusted websites.
