CBC padding attacks To get certificate subscribe: https://www.coursera.org/learn/crypto ======================== Playlist URL: https://www.youtube.com/playlist?list=PL2jykFOD1AWYosqucluZghEVjUkopdD1e ======================== About this course: Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key.

What is ORACLE ATTACK? What does ORACLE ATTACK mean? ORACLE ATTACK meaning - ORACLE ATTACK definition - ORACLE ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In the field of security engineering, an oracle attack is an attack that exploits the availability of a weakness in the system which can be used as an "oracle" which can give a simple go/no go indication to show whether the attacker has reached, or is nearing, their goal. The attacker can then combine the oracle with systematic search of the problem space to complete their attack. The padding oracle attack, and compression oracle attacks such as BREACH, are examples of oracle attacks, as was the practice of "crib-dragging" in the cryptanalysis of the Enigma machine. An oracle need not be 100% accurate: even a small statistical correlation with the correct go/no go result can frequently be enough for a systematic automated attack. In a compression oracle attack the use of adaptive data compression on a mixture of chosen plaintext and unknown plaintext can result in content-sensitive changes in the length of the compressed text that can be detected even though the content of the compressed text itself is then encrypted. This can be used in protocol attacks to detect when the injected known plaintext is even partially similar to the unknown content of a secret part of the message, greatly reducing the complexity of a search for a match for the secret text. The CRIME and BREACH attacks are examples of protocol attacks using this phenomenon.

The Padding Oracle Attack (Part 2) - Performing the attack
In this video I go through the actual mechanisms of the padding oracle attack. The attack exploits any CBC-mode block cipher that alerts the user to malformed padding to recover the full plaintext. This attack has been, and is, used in the wild. Source required to follow: https://corvuscrypto.com/posts/padding-oracle-attack-part-two#files Errata: ~4:25 - I meant to say PKCS #5 as a padding SPECIFICATION. PKCS #5 is a set of rules. Padding is only a part of it. Sorry :')

SSLv3 Poodle Vulnerability | Password theft
All systems and applications utilizing the Secure Socket Layer (SSL) 3.0 with cipher-block chaining (CBC) mode ciphers may be vulnerable. However, the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack demonstrates this vulnerability using web browsers and web servers, which is one of the most likely exploitation scenarios. Some Transport Layer Security (TLS) implementations are also vulnerable to the POODLE attack. The POODLE attack can be used against any system or application that supports SSL 3.0 with CBC mode ciphers. This affects most current browsers and websites, but also includes any software that either references a vulnerable SSL/TLS library (e.g. OpenSSL) or implements the SSL/TLS protocol suite itself. By exploiting this vulnerability in a likely web-based scenario, an attacker can gain access to sensitive data passed within the encrypted web session, such as passwords, cookies and other authentication tokens that can then be used to gain more complete access to a website (impersonating that user, accessing database content, etc.).

RuhrSec 2018: "The ROBOT Attack", Hanno Böck
Abstract. 20 years ago Daniel Bleichenbacher discovered an attack against RSA as it was used in SSL and the padding mode PKCS #1 v1.5. Obviously such an old attack doesn't work any more today, because everyone has fixed it. Okay... That was a joke. It still works. With some minor modifications we were able to discover the ROBOT attack (Return Of Bleichenbachers Oracle Threat). It affected nine different vendors and we were able to sign a message with the private key from facebook.com. More info at https://robotattack.org/ and in the full paper at https://eprint.iacr.org/2017/1189 Biography. Hanno Böck is a freelance journalist and regularly covers IT security topics for Golem.de and other publications. He also writes the monthly Bulletproof TLS Newsletter. In 2014 he started the Fuzzing Project, an effort to improve the security of free software applications. This work is supported by the Linux Foundation's Core Infrastructure Initiative.
