CVE-2025-59419: Critical SMTP Injection Flaw in Netty Library Allows Full Bypass of SPF, DKIM, and DMARC

A critical zero-day vulnerability, CVE-2025-59419, has been discovered in the widely used Netty Java library, affecting countless applications that handle email. The flaw allows an unauthenticated attacker to perform SMTP injection by embedding carriage return and line feed characters into email commands. This enables them to bypass standard email authentication defenses like SPF, DKIM, and DMARC, making it possible to send highly convincing spoofed emails that appear to originate from trusted domains. A patch is available and should be applied immediately.

MuddyWater Cyber-Espionage Campaign Uses Compromised Mailbox and Macros to Deploy Phoenix v4 Backdoor

The Iranian state-sponsored threat group MuddyWater is conducting a large-scale cyber-espionage campaign targeting over 100 government entities, primarily in the Middle East and North Africa (MENA). According to Group-IB, the attackers are using phishing emails sent from a compromised mailbox, leveraging the NordVPN service for anonymity. The emails contain malicious Word documents that use macros to deploy version 4 of the 'Phoenix' backdoor, a payload designed for foreign intelligence gathering. The campaign highlights the group's return to classic macro-based attack vectors.
