For Episode 24 of the Efani Features Podcast, host Mark Kreitzman sits down with Rivka Tadjer, Founder and CEO of ZeroHack, for a fascinating conversation about cybercrime, executive security, AI-driven scams, remote work vulnerabilities, and why your smartphone has become one of the biggest attack surfaces in modern cybersecurity.

Drawing on her background in journalism, fintech, cybersecurity, and service on the White House National Infrastructure Advisory Council's cybersecurity working group, Rivka explains why traditional enterprise security models no longer work in a world where employees, executives, and families are constantly connected through personal devices, home networks, and cloud services.

Rather than focusing solely on corporate infrastructure, ZeroHack was built around a different reality: individuals are now the primary entry point into organizations. Whether you're a CEO, entrepreneur, investor, remote worker, or simply someone who uses a smartphone, understanding cybercrime has become essential.

In this episode:

• Why more than 40% of enterprise compromises begin with individuals rather than corporate systems
• The hidden cybersecurity risks of remote work, family Wi-Fi networks, and BYOD (Bring Your Own Device) environments
• How hackers exploit personal Apple IDs, family plans, and shared digital ecosystems to gain access to sensitive accounts
• Why executives remain some of the most vulnerable targets despite having access to sophisticated security tools
• The importance of separating personal, financial, and business identities online
• Why your bank and brokerage accounts should never use the same email addresses you use for everyday activities
• How cybercriminals use breached data, social engineering, and AI to profile victims before launching attacks

Rivka also shares practical advice on creating ”silos” between different parts of your digital life, protecting financial accounts, securing email identities, and reducing your overall attack surface without sacrificing convenience.

AI, Deepfakes & The Future of Cybercrime

One of the most eye-opening parts of the discussion focuses on how artificial intelligence is changing the threat landscape.

Mark and Rivka discuss:

• AI-powered impersonation scams
• Deepfake video and voice attacks
• Business email compromise
• Fraudulent wire transfer schemes
• The dangers of breached datasets being used to train future attack models
• Why ”delete my data” is no longer an effective security strategy

Rivka explains why organizations must stop playing defense and instead adopt proactive security strategies that make stolen information useless to attackers.

Travel Security, SIM Swaps & Mobile Threats

The conversation also dives into:

• SIM swapping attacks and caller ID spoofing
• Fake kidnapping scams
• International travel security risks
• Metadata exposure through photos and social media
• Hotel security mistakes travelers commonly make
• How organized cybercrime groups operate globally today

Perhaps the most important takeaway is Rivka's message that cybersecurity is not about fear – it's about understanding how criminals operate so you can avoid becoming a victim.

Whether you're protecting personal assets, securing your family, running a business, or simply trying to stay safe online, this episode delivers practical advice that anyone can implement immediately.
