What are Rootkits?Ī rootkit is a collection of malware designed to give unauthorized access to a computer or area of its software and often masks its existence or the existence of other software.

Unlike computer viruses and worms, trojans do not generally attempt to inject malicious code into other files or propagate themselves. Ransomware attacks are also carried out using trojans. Trojans can give access to personal information such as internet activity, banking login credentials, passwords or personally identifiable information (PII). While the payload of a trojan can be anything, most act as a backdoor giving the attacker unauthorized access to the infected computer. Once the executable file is opened, the trojan is installed.

Trojans are generally spread with social engineering such as phishing.įor example, a user may be tricked into executing an email attachment disguised to appear genuine (e.g. The term is derived from the Ancient Greek story of the deceptive Trojan Horse that led to the fall of the city of Troy. What is a Trojan Horse?Ī trojan horse or trojan is any malware that misleads users of its true intent by pretending to be a legitimate program. The Morris worm and Mydoom caused major disruptions by increasing network traffic despite their benign nature. While many worms are designed to only spread and not change systems they pass through, even payload-free worms can cause major disruptions. WannaCry is a famous example of a ransomware cryptoworm that spread without user action by exploiting the EternalBlue vulnerability. This is different to viruses which almost always corrupt or modify files on the victim's computer.

Worms almost always cause at least some harm to a network, even if only by consuming bandwidth. Often, worms use computer networks to spread, relying on vulnerabilities or security failures on the target computer to access it. What is a Computer Worm?Ī computer worm is a self-replicating malware program whose primary purpose is to infect other computers by duplicating itself while remaining active on infected systems. ransomware), send a message, personal amusement, demonstrate vulnerabilities exist, sabotage and denial of service, or to simply explore cybersecurity issues, artificial life and evolutionary algorithms.Ĭomputer viruses cause billions of dollars worth of economic damage by causing system failure, wasting resources, corrupting data, increasing maintenance costs, logging keystrokes and stealing personal information (e.g.

The Microsoft Windows and Mac operating systems are the targets of the vast majority of viruses that often use complex anti-detection strategies to evade antivirus software. Virus writers use social engineering and exploit vulnerabilities to infect systems and spread the virus. When this replication succeeds, the affected areas are then said to be infected. What are Computer Viruses?Ī virus is a type of malware that, when executed, self-replicates by modifying other computer programs and inserting their own code.

Another example is fileless malware that only exists in a system's RAM to avoid being detected.ĭifferent types of malware have unique traits and characteristics, we'll cover 22 in this post. Evasion techniques can be simple tactics to hide the source IP address and include polymorphic malware, which changes its code to avoid detection from signature-based detection tools. Sophisticated malware attacks use a command-and-control server to allow attackers to communicate with the infected computer system, steal sensitive information from the hard drive or gain remote access to the device.Įmerging strains of malware cyber attacks include evasion and obfuscation techniques designed to fool users, security administrators and anti-malware products.

Phishing is another common malware delivery method where emails disguised as legitimate messages contain malicious links or email attachments that deliver executable malware to unsuspecting users. For example, WannaCry, a famous ransomware attack was able to spread by exploiting a known vulnerability. These malicious programs can steal, encrypt or delete sensitive data, alter or hijack key computing functions and to monitor the victim's computer activity.Ĭybercriminals use a variety of physical and virtual means to infect devices and networks with malware. Common types of malware include computer viruses, ransomware, worms, trojan horses and spyware. Malware, or malicious software, is any program or file that harms a computer or its user.
