First Physical Retaliation for a Cyberattack

Israel has acknowledged that its recent airstrikes against Hamas were a real-time response to an ongoing cyberattack. From Twitter:

CLEARED FOR RELEASE: We thwarted an attempted Hamas cyber offensive against Israeli targets. Following our successful cyber defensive operation, we targeted a building where the Hamas cyber operatives work.

I expect this sort of thing to happen more — not against major countries, but by larger countries against smaller powers. Cyberattacks are too much of a nation-state equalizer otherwise.

EDITED TO ADD (5/7): Commentary.

I doubt that this is actually the first “kinetic” retaliation to a cyber attack; however it’s probably the first one to be openly acknowledged by either of the parties involves. Schneier’s observation that cyberwarfare is an equaliser is correct and it’s exactly why a savvy nation-state would consider this kind of response… but let’s not forget that such cyberattacks are only as viable as they are because nation-states favour cyber-offense over cuber-defence in the first place: they’re interested in building 0-day weapons that they can use against their enemies (and their own citizens) and this entire approach runs counter to the idea of improving defensive security.

A Conspiracy To Kill IE6

The plan was very simple. We would put a small banner above the video player that would only show up for IE6 users. It would read “We will be phasing out support for your browser soon. Please upgrade to one of these more modern browsers.” Next to the text would be links to the current versions of the major browsers, including Chrome, Firefox, IE8 and eventually, Opera. The text was intentionally vague and the timeline left completely undefined. We hoped that it was threatening enough to motivate end users to upgrade without forcing us to commit to any actual deprecation plan. Users would have the ability to close out this warning if they wanted to ignore it or deal with it later. The code was designed to be as subtle as possible so that it would not catch the attention of anyone monitoring our checkins. Nobody except the web development team used IE6 with any real regularity, so we knew it was unlikely anyone would notice our banner appear in the staging environment. We even delayed having the text translated for international users so that a translator asking for additional context could not inadvertently surface what we were doing. Next, we just needed a way to slip the code into production without anyone catching on.

The little-told story of how a rogue team of YouTube engineers in 2009 helped hasten IE6‘s downfall by adding a deprecation warning to the top of the site’s homepage… without getting the (immediate) attention of the senior developers and management who’d have squashed their efforts.
