Malware Protection

Malware is a common cyber-attack and an umbrella term for various malicious programs delivered and installed on end-user systems and servers. These attacks are designed to cause harm to a computer, server, or computer network, and are used by cybercriminals to obtain data for financial gain. The average total cost to resolve malware attacks increased 139% from $338,098 in 2015 compared to $807,506 in 2021. A malware attack resulting in a data breach due to data exfiltration could cost an organization an average of $137.2 million. Source: Ponemon’s “The Cost of Phishing Study”

Types of Malware

  • Ransomware: Encrypts files that cannot be recovered unless the victim pays a ransom. Ransomware attacks are all too common these days.
  • Adware: Display ads (sometimes malicious ads) to users as they work on their computers or browse the web.
  • Fileless malware: Instead of using an executable file to infect computer systems, fileless malware uses Microsoft Office macros, WMI (Windows Management Instrumentation) scripts, PowerShell scripts, and other management tools.
  • Viruses: A virus infects a computer and performs a variety of payloads. It may corrupt files, destroy operating systems, delete or move files, or deliver a payload at a specific date.
  • Worms: A worm is a self-replicating virus, but instead of affecting local files, a worm spreads to other systems and exhausts resources.
  • Trojans: A Trojan is named after the Greek war strategy of using a Trojan horse to enter the city of Troy. The malware masquerades as a harmless program, but it runs in the background stealing data, allowing remote control of the system, or waiting for a command from an attacker to deliver a payload.
  • Bots: Infected computers can become a part of a botnet used to launch a distributed denial-of-service by sending extensive traffic to a specific host.
  • Spyware: Malware that installs, collects data silently, and sends it to an attacker that continuously “spies” on users and their activities. Spyware aims to gather as much important data as possible before detection.
  • Backdoors: Remote users can access a system and possibly move laterally. Trojans deliver backdoor payloads during installation.
  • Banking Trojans: View or steal banking credentials to access accounts. Typically, they manipulate web browsers to trick users into entering their personal banking information.
  • Keyloggers: Capture keystrokes as users type in URLs, credentials, and personal information and send it to an attacker.
  • RAT: “Remote access tools” enable attackers to access and control the targeted device remotely.
  • Downloaders: Download other malware to install locally. The type of malware depends on the attacker’s motives.
  • POS: Compromise a point-of-sale (PoS) device to steal credit card numbers, debit card and PINs, transaction history, and contact information.
