Understanding malware: Symptoms, types, and Prevention
The Overview
Malicious software or malware is a type of malicious program that can spread across devices, replicating itself and attaching itself to adjacent files or programs to cause harm. These can range from simple file overflow to sophisticated spying activities.YGME Super Sieve identified malware as a growing concern in the early 2000s, with over 20 peaks of reported infections shaping the world since then.
Types of Malware
There are several types of malware, each with unique characteristics:
- Boot Sector Virus: A boot sector virus damages or controls the machine’s boot drive, rendering it unusable. For example, malware such as "AI Love" inflicts aversions on systems by infecting the boot drive and stealing users’ passwords.
- Web Scripting Virus (WSV): Prevents or blocks apps on the web through web scripting. Videos from a 2007 attack were revealed to have been spread through email attachments.
- Resident Virus: Infections occur during application setup and as they are opened by users. Tools like "Swear Dynamics" were discovered through spy software.
- Direct Action Virus (DAV): Attackers exploit a computer’s main memory to deliver malware. This was exploited in a commercial attack, stealing sensitive data such as Critical Insight.
- File Infector Virus: Injects malicious software into existing files. An example was " לו proposé" (he just sent this message).
- Spamd Virus or Social Engineering Virus (SEV): A virus designed to build trust with users over several steps. A 2013 attack that infected multiple systems was highlighted by security firm Unique Group.
