Cyber Warfare: Army Deploys Social Media Warfare Division To Fight Russia

The U.K.s new special cyber operations unit, 6 Division (6 Div), will move beyond the typical cyber capabilities within the military sphere into full-blown social media "information warfare." And here the primary adversary is Russia, which has turned the dark art of peddling fake news and political propaganda across major social media platforms into a national security strategy.

Much of the work of the new unit will be relatively traditional signals activities—jamming and intercepting enemy comms, supporting the field world of allied intelligence agencies.

Forget Facebook, Snapchat, Twitter: TikTok Is The Breakout COVID-19 Social Media Platform

Social media has been one of only a handful of sectors that is benefiting from the stay-at-home environment. Social distancing has forced social interactions online for the time being, but investors looking to capitalize on the surge in social media usage be surprised at the big winner.

On Friday, DataTrek Research co-founder Nicholas Colas said the biggest social media winner from the COVID-19 era is not Facebook, Inc.
FB , its subsidiary Instagram, Snap Inc  SNAP 0.06% or Twitter Inc TWTR 0.02%

Instead, teen-oriented video platform TikTok has seen the biggest surge in Google search volume over the last 90 days. TikTok is owned by the private Chinese company ByteDance.

How social media feels about the coronavirus

An Italian-based artificial intelligence company is regularly analyzing social media posts about the coronavirus for their emotional content.

Why it matters: Classifying tens of thousands of posts by their emotional tone provides a snapshot of how people feel about the pandemic. Spoiler alert: not great!

How it works: Expert System specializes in semantics and natural language reading, a branch of AI involving computer systems that attempt to make sense of written language.

In doing so, a computer can rapidly analyze vast amounts of the written word — like, for example, a day's worth of social media posts about the COVID-19 pandemic.
For the past few weeks, Expert System has been collecting English language social media posts each day that feature frequently used hashtags like #coronalockdown and #covid19. Its AI can extract the emotional content of those posts, which is then analyzed and interpreted by Sociometrica.
