Struggling cryptocurrency exchange FTX said on Saturday it was moving funds to offline storage after reports of “unauthorized transactions”. Analysts said assets worth millions of dollars had been pulled from the platform. “Following the Chapter 11 bankruptcy filings – FTX US and FTX [dot] com initiated precautionary measures to transfer all digital assets to cold storage. The process was accelerated this afternoon – to mitigate the damage after unauthorized trading was observed,” FTX US general counsel Ryan Miller tweeted. Cold storage refers to crypto wallets that are not connected to the internet to protect them from hackers. INSIDE THE FTX CRYPTO EXCHANGE CRASH: EVERYTHING YOU NEED TO KNOW Miller had previously written that FTX was “investigating anomalies with wallet movements related to the consolidation of FTX balances on exchanges,” though he noted that the facts were unclear “like other movements [were] not clear.” An admin on the official FTX Telegram channel wrote that “Ftx has been hacked.” This administrator told users not to visit the FTX website “as it may download Trojans”. “Some funds recovered,” FTX admin wrote.

Data from Singapore-based analyst Nansen showed a one-day net outflow from FTX of about $266 million, with $73 million withdrawn from FTX US Sam Bankman-Fried, founder and CEO of FTX Cryptocurrency Derivatives Exchange, during an interview on an episode of Bloomberg Wealth with David Rubenstein in New York, August 17, 2022.

Two sources told Reuters that Bankman-Fried – in a meeting he confirmed took place – shared files with other senior executives that revealed the financial hole. The spreadsheets reportedly showed that between $1 billion and $2 billion of the funds were not included in Alameda’s assets, and that the spreadsheets did not show where the money was moved.

Bankman-Fried denied implementing a “backdoor.” FOX Business’ request for further comment from Bankman-Fried was not immediately returned.
