This claim may mislead readers without added context.

Over $5B was stolen.

Can’t verify
Blockchain estimates ranged from roughly $5.3 billion to $5.9 billion, but some figures represented assets held in tracked wallets rather than confirmed stolen funds.boxmining.com bleepingcomputer.com

Governments are telling people to stockpile 90 days of food and water.

Can’t verify
No supporting government announcement or authoritative report was found in the available sources.

Assessment summary

  • The statement contains multiple significant inaccuracies and misleading claims.
  • While the crypto hack amount is roughly accurate, the claim about 90-day stockpiling conflates military planning with public guidance, Japan's "declaration" was not formal, and two major claims lack any supporting evidence.

Claims reviewed

Japan declared state of emergency in cyberspace.

Misleading
Japan has not formally declared a state of emergency in cyberspace krdo.com. A ruling party official characterized the situation as such at a party meeting, but this was not an official government declaration fortune.com.

This claim may mislead readers without added context.

Governments telling people to stockpile 90 days of food and water.

Misleading
The Pentagon is preparing military bases for 90 days of self-sufficiency krdo.com, but the British government told civilians to prepare for only 3 days fortune.com. The claim conflates military planning with public guidance to civilians.

This claim may mislead readers without added context.

Iran threatening undersea cables.

Can’t verify
No evidence found in current reporting about Iran threatening undersea cables in connection with recent cyber events.

Assessment summary

  • Some statements match recent reporting, but others are false or lack clear sourcing.
  • Key numeric and prescriptive claims are either incorrect or unsupported by reliable public sources.
  • I cite news reports that confirm the verified parts and contradict or fail to confirm the rest.

Claims reviewed

Governments telling people to stockpile 90 days of food and water.

Incorrect
Recent reporting shows the U.S. Pentagon is planning for 90-day resilience at bases, and some governments have urged preparedness, but public government guidance urging civilians to stockpile 90 days is not supported; most public advisories (e.g., UK) recommend much shorter durations (three days). fortune.com telegraph.co.uk

The LARGEST crypto hack in history just happened. Over $5B stolen.

Misleading
Multiple news and on-chain analyses report a very large Binance-related drain of roughly $5–5.8 billion across chains, which would be among the largest crypto heists; however whether it is definitively 'the largest in history' depends on classification (exchange hot wallet vs bridge vs protocol) and confirmation from the exchange, so calling it simply 'the LARGEST' is misleading. drk.vc news.ycombinator.com

This claim may mislead readers without added context.

Elon says hacking about to go exponential.

Can’t verify
I found informal/short Musk comments (e.g., 'Everyday is Zeroday' or archived posts) but no clear public quote where Elon Musk explicitly said 'hacking about to go exponential.' This exact wording lacks a reliable primary source. source unavailable
