MasterCard’s Long-Standing DNS Error: A Hidden Issue Unveiled

MasterCard’s DNS Error: A Hidden Issue Unveiled

The payment card giant MasterCard recently addressed a significant error in its domain name server (DNS) settings that had the potential to compromise its internet traffic. This misconfiguration, which lasted nearly five years, was only rectified after a security researcher took proactive measures to secure an unused domain name.

Summary

MasterCard’s DNS misconfiguration could have allowed malicious actors to intercept or redirect internet traffic. A security researcher intervened by registering the unused domain, preventing potential exploitation by cybercriminals.

Key Points

  • MasterCard fixed a critical DNS misconfiguration.
  • The error persisted for almost five years.
  • A security researcher spent $300 to register the unused domain.
  • The registration prevented cybercriminals from exploiting the vulnerability.

This incident highlights the importance of robust DNS management and the need for continuous monitoring to safeguard against potential threats in the digital landscape.

OpenSSL Flaw Exposes Servers to Memory Exhaustion Attacks

A newly discovered OpenSSL flaw, dubbed HollowByte, leaves unpatched servers vulnerable to memory exhaustion attacks, where a mere 11 bytes can trigger the allocation of up to 131 KB of memory for a message that never arrives. This tiny trigger can bring a server to its knees, freezing memory and blocking critical connections.

OpenSSL Servers Vulnerable to Memory-Bloating DDoS Attacks

Beware: a simple 11-byte malicious input can cripple OpenSSL servers with a devastating DDoS attack, leaving them permanently bloated and vulnerable. This sneaky exploit, dubbed HollowByte, takes advantage of a weakness in OpenSSL's TLS handshake to drain server resources.
