Indian certificate authority eMudhra’s cryptographic security vulnerability has impacted Ethereum clients Teku and Besu. Researchers discovered that the private keys of 8 intermediate certificate authorities under eMudhra may be derivable due to insufficient randomness, enabling attackers to forge certificates and trick unpatched software into trusting malicious services. Teku has released version 26.10.3, and Besu has released version 26.10.2, both removing trust in the relevant certificates from their Docker images. Attackers could carry out man-in-the-middle attacks to deceive some validators into sending block fee rewards to attacker addresses; the risk is higher in specific configurations using external signers. The Teku team noted that Teku nodes on Ethereum mainnet with default configurations are not affected, requiring no action, and there have been no reports of the vulnerability being exploited. For operators running Teku or Besu directly on hosts without Docker, updating the client alone is insufficient—they must also manually update Java and its trusted certificate list. Operators still using end-of-life Java 26 need to migrate to Java 25.

Euronext suspended trading of CoinShares’ newly launched Zcash ETP (ticker: ZCSH) on its Paris market on October 28, just hours after the product’s launch. An Euronext spokesperson stated the suspension stemmed from the central securities depository (CSD) being unable to support standard settlement operations, not regulatory concerns, and the product will resume once settlement conditions are met. The ZEC-backed, euro-denominated product carries an annual fee of 1.50%. Zcash ETPs from 21Shares, Virtune, and Valor remain actively traded in Europe.
