Using an old security patch invites the attackers to enter and steal. Hackers unknowingly use the information gathered by security researchers for their use. However, any unfixed vulnerabilities are being exploited by hackers for their personal use. To identify them for future reference, these exploits are categorized into hundreds of Common Vulnerabilities and Exposures (CVEs).
Unfortunately, many breaches are not due to automation failure or unknown error but are expected to be human error. According to a study, 50% of breaches happen due to some human error. The reason maybe

Keep a record of all of your financial receipts.
If you receive any mail from suspicious-looking emails, don’t open it without proper investigation. Before opening any attachment, be sure you know who the sender is and what the email contains.
