A potential security threat prompted Binance, the largest cryptocurrency exchange, to revoke Application Programming Interface (API) keys connected to SignalPlus, a third-party institutional-grade technology firm. Announcing the decision on Thursday, the exchange described it as a precautionary step.

Are Binance systems affected?

Customers' funds are safe and Binance's systems remain unaffected, the exchange assured users. It advised SignalPlus users to access their Binance accounts directly and check their positions and open orders. Before linking any API keys again, users should wait for SignalPlus to confirm that the potential security issue has been fully resolved, Binance said. It also asked them to activate wallet whitelisting.

Binance has also asked integrated third-party platforms to assess their security controls and watch for unusual activity. Should they identify any concerns, they have been requested to contact the exchange immediately.

As a precaution, Deribit too revoked API keys connected to SignalPlus, although it said it had found no evidence of a compromise involving its systems or data. Nevertheless, it advised users to check their positions and open orders, and await confirmation from SignalPlus that the potential security threat had been neutralised.

Other exchanges were subsequently urged to revoke API keys connected to SignalPlus by Binance co-founder Changpeng Zhao, popularly known as CZ.

CZ offered this advice: “It is generally recommended that you do not store your API keys with any 3rd party platform,”

Last week's hack on Binance's platform, which impacted roughly $6.3 billion, forms the backdrop to its proactive revocation of SignalPlus API keys. TraderTraitor, a North Korean-linked hacker group, was largely blamed for the security breach. By absorbing all losses, Binance bore the cost in what was viewed as an effort to build trust. Earlier this week, reports indicated that panic-driven outflows following the resumption of withdrawals had eased, while Binance reported net inflows.

FAQs on cryptocurrency price movements

What impact do new token launches and exchange listings have on cryptocurrency prices?

Demand and adoption among market participants are influenced by token launches. When an asset is listed on a crypto exchange, its liquidity deepens and new participants join its network. Digital assets typically benefit from this bullish development.

Why can hacks move cryptocurrency prices?

During a hack, an attacker uses exploits, bugs or other methods to seize a large quantity of an asset from a DeFi bridge, an exchange's hot wallet or another crypto platform. The stolen tokens are then moved out of exchange platforms, with the ultimate aim of selling them or swapping them for other cryptocurrencies or stablecoins. Widespread panic often follows such incidents, setting off a sell-off in the affected assets.

How do economic data releases and macroeconomic events influence cryptocurrency prices?

The direct effect on the US Dollar is the main channel through which macroeconomic events, such as interest rate decisions by the US Federal Reserve, influence crypto assets. Bitcoin and altcoin prices typically come under pressure when interest rates rise, while the reverse also holds. A fall in the US Dollar index makes risk assets and the leverage used to trade them cheaper, thereby pushing crypto prices higher.

What do major crypto upgrades, including halvings and hard forks, mean for cryptocurrency prices?

By cutting miners' block rewards in half, halvings restrict an asset's supply and are therefore generally viewed as bullish events. With demand unchanged, a reduction in supply pushes the asset's price higher.
