Education: M.A. in translation and interpreting

Highlights of your career: Wearing two career hats for the better part of the past ten years while retaining a semblance of normality.

Position and history of ESET I joined ESET as a security writer in late 2017 after being bitten by the cybersecurity bug.

What malware do you hate the most Ransomware (for adding insult to injury, literally).

Favorite activities: Reading, cycling, travelling.

Golden rule for cyberspace? 'Distrust and caution are the parents of security.' Benjamin Franklin’s thoughtful advice from 300 years ago nicely applies to cyberspace.

When did you get your first computer and what kind was it? A gifted 386 PC in the mid-1990s. It worked a little erratically, though (or maybe it was a classic example of 'problem exists between keyboard and chair'?)

Favorite computer game / activity: I'm a bit of a power user of RSS feeds, which I use to indulge my news consumption habit while keeping empty ‘news calories’ at bay.
