   "summary": "An attacker abused an authorization flaw in email platform Brevo to reach 138 client accounts and send phishing from six of them. One was a fake Trezor 'Critical Security Alert: STM32 Entropy Vulnerability' sent to about 347,000 Trezor newsletter subscribers, linking to an app that asked for wallet backups; BitBox's list and CoinTracking (a fake 'refresh API keys' email) were also used. Trezor took the phishing domain down within 20 minutes; about 2,500 people opened the link and no losses have been reported. Recipients should expect follow-up phishing to the same addresses."
