Remote Access Trojans (RATs) are a type of malware that give cybercriminals unauthorized access to a victim’s computer or network. RATs are often distributed through Intrusion Detection System (IDS): A system that monitors net... emails, malicious downloads, or vulnerabilities in software. Once installed, RATs allow attackers to remotely control the infected system, stealing sensitive information, disabling Data Retention: Policies that determine how long data should..., or deploying further malware.
Common RAT Tactics and Techniques
RATs employ various tactics and techniques to gain control over targeted systems. Some of the most prevalent methods include:
1. Remote Access Trojan (RAT): A type of malware that provides ...
Cybercriminals often use social engineering techniques to trick users into installing RATs unknowingly. This can be through convincing phishing emails, deceptive file attachments, or malicious links.
2. Exploiting Software Vulnerabilities
RATs can exploit vulnerabilities in software, such as operating systems or popular applications, to gain unauthorized access. These vulnerabilities are often patched by software developers, but users who fail to update their software remain at risk.
3. Drive-by Downloads
RATs can be silently downloaded and installed without the user’s knowledge while visiting compromised or malicious websites. This method is known as a Malvertising: Malicious online advertising that contains mal... and takes advantage of security vulnerabilities in web browsers and plugins.
Capabilities of Remote Access Trojans
RATs possess a wide range of capabilities that allow attackers to perform various malicious activities:
1. Remote Control
RATs grant cybercriminals full or partial control over an infected system, enabling them to execute commands, manipulate files, browse directories, and perform other actions remotely.
Many RATs have keylogging capabilities, allowing attackers to record keystrokes on the infected system. This technique enables the theft of sensitive information like Incognito Mode: A privacy setting in web browsers that preve... and credit card details.
3. Screen Capture and Webcam Hijacking
RATs can capture screenshots or even take control of a victim’s webcam, invading their Tor (The Onion Router): Free software for enabling anonymous... and potentially capturing sensitive information or compromising material.
4. File Transfer and Data Theft
RATs facilitate the transfer of files between the infected system and the attacker’s server. This function often enables the theft of sensitive data, such as Swatting: A harassment tactic where a perpetrator deceives a... or corporate secrets.
