Don't use functions as callbacks unless they're designed for it

Here's an old pattern that seems to be making a comeback: // Convert some numbers into human-readable strings: import toReadableNumber from 'some-library'; const readableNumbers = someNumbers.maptoReadableNumber; Where the implementation of toReadableNumber is like this: export function...

Microsoft surpasses $10 billion in security business revenue, more than 40 percent year-over-year growth

I joined Microsoft a little more than six months ago—amid a global pandemic and a new norm of remote work, as well as one of the most rapidly evolving threat landscapes in history. We’ve witnessed more sophisticated attacks, like the recent SolarWinds incident, as well as an increase in attack...

Exfiltrating Data from Air-Gapped Computers via Wi-Fi Signals (Without Wi-Fi Hardware)

A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed "AIR-FI," the attack hing...
