Modified package published to npm, containing malware that exfiltrates private key material

Description

Earlier today, a publish-access account was compromised for @solana/web3.js, a JavaScript library that is commonly used by Solana dapps. This allowed an attacker to publish unauthorized and malicious packages that were modified, allowing them to steal private key material and drain funds from dapps, like bots, that handle private keys directly.

Recommendation

Update the @solana/web3.js package to the latest compatible version. Followings are version details:

• Affected version(s): >= 1.95.6, < 1.95.8
• Patched version(s): 1.95.8
