RAMBleed Side-Channel Attack Exposes Privileged Memory

A team of academic researchers has discovered a follow-on to the Rowhammer class of attacks that allows attackers to read memory data on a target Windows computer, without actually accessing the memory itself. The method is dubbed RAMBleed. Andrew Kwong and Daniel Genkin at the University of...

RAMBleed Attack – Flip Bits to Steal Sensitive Data from Computer Memory

A team of cybersecurity researchers yesterday revealed details of a new side-channel attack on dynamic random-access memory DRAM that could allow malicious programs installed on a modern system to read sensitive memory data from other processes running on the same hardware. Dubbed RAMBleed and...

Side-channel Attack

httpd is vulnerable to side-channel attack. An implementation flaw was discovered in multiple cryptographic libraries that allows a side-channel based attacker to recover ECDSA or DSA private keys. When these cryptographic libraries use the private key to create a signature, such as for a TLS or...
