Brute force attacks on cryptography could take billions of years, which no one has to spare. Maybe you live in a country where rubber hose cryptography is, shall we say, frowned upon. Hacking a target's endpoint is an option, but what if you get caught? Better to use an attack that leaves no forensic traces behind. . Enter side channel attacks. A side channel attack breaks cryptography by using information leaked by cryptography, such as monitoring the electromagnetic field (EMF) radiation emitted by a computer screen to view information before it's encrypted in a van Eck phreaking attack, aka Transient Electromagnetic Pulse Emanation STandard (TEMPEST). Other well-known side channel attacks include spying on the power consumption of an electronic device to steal an encryption key, or acoustic attacks that record the sound of a user's key strokes to steal their passphrase. .

Piercing a key selling point of commercial cloud computing services, computer scientists have devised a hack that allows an attacker using Amazon's EC2 platform to steal the secret cryptographic keys of other users. . The proof-of-concept attack is significant because Amazon Web Services and many other cloud service providers already blocked a previous key-recovery attack on co-located virtual machines that was unveiled in 2009. The paper was one of the first to highlight the security risks that come when someone uses the same physical piece of hardware as an advanced attacker. Cloud providers and makers of cryptography and virtual-machine software patched many of the weaknesses that made the attack possible. As a result, many of the techniques that gave the 2009 attack a high degree of accuracy are no longer possible. . This proof-of-concept attack illustrates how AWS can be exploited to obtain secret keys for malicious purposes.. AWS Exploit, Cloud Security, Cryptographic Key Attack, Cloud Computing. .
