Trait 1: Viruses
Viruses are a type of malware that can replicate themselves and infect other files or systems. They often attach themselves to executable files or documents. Some examples of viruses include:
1. ILOVEYOU: This virus, spread through email, was one of the most destructive worms in history, affecting millions of computers worldwide in 2000. It would replicate itself and overwrite random files, causing widespread damage.
2. Melissa: Melissa was another email-based virus that caused significant disruption in 1999. It spread through infected Word documents, sending itself to the top 50 contacts in the victim's email.
Trait 2: Worms
Worms are standalone malware that can spread and replicate independently without requiring host files. They exploit vulnerabilities in computer networks to self-replicate. Examples of worm malware include:
1. Conficker: The Conficker worm infected millions of computers globally in the late 2000s. It exploited Windows vulnerabilities and spread across networks, allowing hackers remote control over compromised machines.
2. Blaster: Blaster, also known as MSBlast, targeted Windows operating systems in 2003. It exploited a vulnerability in the Remote Procedure Call (RPC) service, causing infected computers to crash and launch denial-of-service attacks.
Trait 3: Trojans
Trojans, named after the historical story of the wooden horse, appear as legitimate software but contain malicious code. Users unknowingly install them, allowing unauthorized access or control over their systems. Examples of Trojan malware include:
1. Zeus: Zeus, a notorious Trojan, aimed to steal banking credentials and financial information. It infected millions of computers globally, capturing online banking credentials and conducting fraudulent transactions.
2. Emotet: Emotet, originally a banking Trojan, evolved into a modular malware that can download additional malicious payloads. It is often distributed via phishing emails and is notorious for its ability to evade detection.
Trait 4: Ransomware
Ransomware is a type of malware that encrypts victims' files or locks their entire systems, demanding a ransom payment to restore access. Examples of ransomware include:
1. WannaCry: WannaCry caused a global impact in 2017 by targeting machines running outdated versions of Windows. It encrypted files and demanded a ransom payment in Bitcoin for decryption.
2. Ryuk: Ryuk is an advanced ransomware that specifically targets large organizations. It gained notoriety for demanding substantial ransom payments and for its association with various high-profile attacks.
Please note that the examples provided may have evolved or been replaced by newer variants, as the malware landscape is constantly evolving.
There are different methods for classifying the different instances of malware. One method uses the primary trait that the malware possesses.
