I recently wrote an article for ZDNet with easy-to-understand advice to lock down your phone’s security and privacy.

In June 2017, as NotPetya malware ripped through Ukraine's business and government technology infrastructure, I reported from the capital, Kyiv, for ZDNET's then-sibling publication TechRepublic, moderating panel discussions about geopolitical cyber defense at the Global Cybersecurity Summit. The city was a charming, modern startup hub with innovative thinkers and smart technology.

It was also a hacker trap. The town itself was safe, but targeted with a blend of kinetic and digital attacks by hyper-polarized geopolitical actors. Key hacks included blackouts from power grid attacks in 2015 and 2016 and the NotPetya malware, which started in Ukraine and spread globally. Ukraine's State Treasury was also targeted, which infected military systems and disrupted government sites, especially during the 2022 invasion.

From taking notes to shooting video and audio, I needed my phone to report. Smartphones are essential tools; they're also security and privacy liabilities. In today's expanding surveillance and threat environment, which is full of opportunistic cyberattacks, corporate tracking, and invasive government scrutiny, locking down your phone is smart and often necessary.

Read on ZDNet: 7 ways to lock down your phone's security - before it's too late.
