Solana Confirms Wallet Breach
The Solana Foundation has published new details about today’s attack.
Earlier, nearly 8,000 addresses were drained through what was believed to be a breach of the third-party wallet app Slope.
This afternoon, the Solana Foundation confirmed on the Solana Status Twitter account that the addresses affected by the attack “were at one point created, imported, or used in Slope mobile wallet applications.”
It added that private key information was accidentally transmitted to an application monitoring service. It said that further details “are still under investigation.”
The attack only affected Slope’s downloadable wallet app; Slope hardware wallets are still secure. Though thousands of wallets were drained, the Solana Foundation added that the Solana protocol itself remains secure.
Slope also commented on the situation. It said that a “cohort” of Slope wallets were compromised and confirmed that several of its own staff wallets were drained.
Slope said that it had not confirmed the nature of the attack. “We have some hypotheses as to the nature of the breach, but nothing is yet firm,” Slope said in its official statement. It committed to publishing a full post-mortem in the future.
The company also suggested that users take action to secure their funds. It advised users to create a new seed phrase and wallet and transfer their funds to that wallet.
Both companies say that they are performing internal investigations and working with external auditors.
Various other individuals within the Solana ecosystem provided information and speculated on the attack earlier today.
At least two other projects in the Solana ecosystem have been hacked this year. Cashio was hacked for $28 million in March, while Wormhole was hacked for $322 million in February.
