Top Security Mistakes in Device Use: Insights from a Former Hacker Turned Expert

A former hacker now working as a security consultant at Infosec, sheds light on the common security blunders that leave many vulnerable to cybercriminals. The hacker, whose current role involves probing the cybersecurity defenses of companies to identify weaknesses, outlines five critical errors that are often overlooked by device users.

1. Neglecting Software Updates: He emphasizes the importance of keeping software on phones and computers up to date. He explains that many updates are released to address security vulnerabilities. Once these vulnerabilities are identified and discussed in online hacker forums, they become widely known, increasing the risk of unauthorized access to sensitive information.
2. The Risk of Reusing Passwords: A significant hazard highlighted by the hacker is the habit of using the same password across multiple platforms. He points out that this practice can lead to a domino effect if one site is compromised, potentially giving criminals access to various accounts. Burge notes that large-scale data breaches often result in the distribution of username and password combinations on the dark web, which can be exploited if passwords are reused.
3. Oversharing on Social Media: With the prevalence of social media, the hacker cautions against sharing excessive personal information. He warns that hackers can harvest details such as birthdates, addresses, and answers to common security questions, using them for activities like ‘sim-jacking’ – transferring a mobile number to a new SIM card. This technique can circumvent two-factor authentication and gain access to crucial accounts, including banking.
4. Dangers of Public WiFi Networks: The hacker advises against using unencrypted public WiFi networks found in locations like cafes and airports. He suggests using a VPN (Virtual Private Network) on public networks to encrypt data and protect it from potential interception.
5. Vigilance Against Phishing Attempts: Lastly, the hacker urges users to exercise caution with the links they click, especially in emails and texts. With the rise of phishing scams that appear increasingly authentic, he recommends a vigilant approach to unexpected messages. Avoiding suspicious links and downloads is crucial to prevent falling into traps set by cybercriminals.

The hackers expertise, born from his unique journey from a hacker to a security professional, provides valuable insights into the often-overlooked practices that can significantly enhance our digital safety and security.
