Indicators of compromise

Understanding malware

  • Worm: An autonomous program capable of replicating and propagating itself through the network.
  • Trojan: A program that appears to serve a designated purpose, but also has a hidden malicious capability to bypass security mechanisms, thus abusing the authorization that’s been given to it.
  • Rootkit: A set of software tools with administrator privileges, designed to hide the presence of other tools and hide their activities.
  • Ransomware: A computer program designed to deny access to a system or its information until a ransom has been paid.
  • Keylogger: Software or hardware that records keyboard events without the user’s knowledge.
  • Adware: Malware that offers user-specific advertising.
  • Spyware: Software that has been installed onto a system without the knowledge of the owner or the user, with the intention of gathering information about him/her and monitoring his/her activity.
  • Scareware: Malware that tricks computer users into visiting compromised websites.
  • Backdoor: The method by which someone can obtain administrator user access in a computer system, a network, or a software application.
  • Wiper: Malware that erases the hard drive of the computer it infects.
  • Exploit kit: A package that’s used to manage a collection of exploits that could use malware as a payload. When a victim visits a compromised website, it evaluates the vulnerabilities in the victim’s system in order to exploit certain vulnerabilities.
