It is exploited by hackers before the developers become aware of it and fix it.\n    \u003c/p\u003e\n\u003c/div\u003e\n\n## The Zero-day Predicament\n\nThe term \"zero-day\" originally referred to the number of days since a new piece of software was released to the public. Zero-day software could be obtained by developers who would pay a premium price to get the software first. The term was later applied to the vulnerability itself, and to the kind of exploit that was used to attack it.\n\n### What Are Zero-day Attacks and How Do Zero-day Attacks Work?\n\nA zero-day attack is a cyberattack that occurs on the same day a weakness is discovered in software. At that point, it's exploited before a fix becomes available from its creator. This type of attack exploits the lack of time (the \"zero-day\" part) available to prevent the attack or mitigate its effects.\n\n### Who Carries Out Zero-day Attacks?\n\n- **Cybercriminals** - Hackers whose motivation is usually financial gain.\n- **Hacktivists** - Hackers motivated by political or social causes who want the attacks to be visible to draw attension to their cause.\n- **Corporate Espionage** - Hackers who spy on companies to gain information about them\n- **Cyberwarfare** - Countries or political actors spying on or attacking another country's cyberinfrastructure.\n\n### Who Are the Targets of Zero-day Exploits?\n\n- Operating systems\n- Web browsers\n- Office applications\n- Open-source components\n- Hardware and Firmware\n- Internet of Things (IoT)\n\n## How to Identify Zero-day Attacks\n\n### How to Protect Yourself Against Zero-day Attacks\n\n- Keep all and operating systems up to date\n- Use only essential applications\n- Use a firewall\n- Within organizations, educate users\n- Use a comprehensive antivirus software solution\n- A solution based on behavior analysis could be another way of protection\n- Monitoring unusual program behavior keeps information systems and software secure\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpungrumpy%2Fzero-day-exploit-hands-on","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpungrumpy%2Fzero-day-exploit-hands-on","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpungrumpy%2Fzero-day-exploit-hands-on/lists"}
