I do not see a shred of evidence to support this. Basically a guy in a mask said it happened. 

They should rather give this information to the authorities to deal with. Terrorism is a life and death matter and should be taken seriously. Their own lives might be at risk, if someone from the ISIS side managed to identify them. The CIA NSA and these agencies are fighting these people and are closing their fiat accounts left, right and center all over the world. It is fine to help with a cause, but it is not fine to endanger your own lives or that of your families, if there is a chance that you might drop a clue to their location. I hope you stay hidden and fight any form of injustice in this world. ^smile^

Apparently it was not a terrorist operation. Terror is a political technique used in asymmetrical war. The idea is to cause fear that leads a powerful enemy into bad decisions. For example the 9/11 attacks were highly successful in causing the U.S. to completely restructure our government and society around a theme of fear. We gave up our rights and our freedoms, we squandered our treasure and wrecked our economy, destroyed what credibility we had pursuing stupid wars. We really could not have done more to help Al Qaeda magnify their operation.

The hijacker in Egypt was unclear about his demands, but apparently he mostly wanted to patch things up with his ex-wife. That sounds more like a desperate mentally ill man than a terrorist.  I'm sure we'll find out more soon.

EDIT: Yeah, he does not look very scary too me? Especially when he is taking selfies with the hostages.

This website badly needs to hire journalists to check the facts. What are the facts? How many BTC was stolen? Was the cryptocurrency stolen BTC? Was that cryptocurrency which was stolen? Who was stolen and who made the steal? There's an information in the title, but there isn't any more information in the article. That's how you spread false news.

The article's not exactly a news one more like an opinion column.

@ontopic I think yes, If there's a hot wallet open somewhere in the dark web it's possible to have BTC stolen.

Is it really that easy to hack into Twitter accounts or Anonymous contacted Twitter officials and they closed down the accounts? Also how can they be sure that integrated Muslims living in Europe can't be radicalized at any given moment? I think some of the terrorists have been living in Europe for years. Well at least vigilant hackers want to help the cause of stopping terrorism which is a good thing.

This is almost certainly not true. Anyone can claim to be Anonymous - but what's more is that there is no evidence. Send the coins to a burner address (something along the lines of 1abcISISbyeBYE2UrBTC would be funny).
