Passwords & hash functions (Simply Explained)
 
07:28
How can companies store passwords safely and keep them away from hackers? Well let's find out! With all the data breaches lately, it's likely that the password of one of your accounts has been compromised. Hackers now might know the password you've used, but they also might not.. To understand why, we'll take a look at what methods a company can use to protect user passwords. We'll take a look at encryption, hash functions and a multilayer approach! 📚 Sources Can be found on my website: https://savjee.be/videos/simply-explained/hash-functions/ 🌍 Social Twitter: https://twitter.com/savjee Facebook: https://www.facebook.com/savjee ✏️ Check out my blog https://www.savjee.be
Securing Kubernetes Secrets (Cloud Next '19)
 
42:27
Secrets are a key pillar of Kubernetes’ security model, used internally (e.g. service accounts) and by users (e.g. API keys), but did you know they are stored in plaintext? That’s right, by default all Kubernetes secrets are base64 encoded and stored as plaintext in etcd. Anyone with access to the etcd cluster has access to all your Kubernetes secrets. Thankfully there are better ways. This lecture provides an overview of different techniques for more securely managing secrets in Kubernetes, including secrets encryption, KMS plugins, and tools like HashiCorp Vault. Attendees will learn the trade-offs of each approach to make better decisions on how to secure their Kubernetes clusters.

Module 7: What is IP Spoofing?
 
05:56
Spoofing attack involves using a fake network address to pretend to be a different computer. Attackers may change a computer's network address to appear as an authorized computer IP spoofing can enable an attacker to gain access to protected internal resources.

Efficient Cryptography for the Next Generation Secure Cloud
 
01:05:04
Peer-to-peer (P2P) systems, and client-server type storage and computation outsourcing constitute some of the major applications that the next generation cloud schemes will address. Since these applications are just emerging, it is the perfect time to design them with security and privacy in mind. Furthermore, considering the high-churn characteristics of such systems, the cryptographic protocols employed must be efficient and scalable. In this talk, I will focus on an efficient and scalable fair exchange protocol that can be used for exchanging files between participants of a P2P file sharing system. It has been shown that fair exchange cannot be done without a trusted third party (called the Arbiter). Yet, even with a trusted Arbiter, it is still non-trivial to come up with an efficient solution, especially one that can be used in a P2P file sharing system with a high volume of data exchanged. Our protocol is optimistic, removing the need for the Arbiter's involvement unless a dispute occurs. While the previous solutions employ costly cryptographic primitives for every file or block exchanged, our protocol employs them only once per peer, therefore achieving O(n) efficiency improvement when n blocks are exchanged between two peers. In practice, this corresponds to one-two orders of magnitude improvement in terms of both computation and communication (42 minutes vs. 40 seconds, 225 MB vs. 1.8 MB). Thus, for the first time, a provably secure (and privacy respecting when payments are made using e-cash) fair exchange protocol is being used in real bartering applications (e.g., BitTorrent) without sacrificing performance. Finally, if time permits, I will briefly mention some of our other results on cloud security including ways to securely outsource computation and storage to untrusted entities, official arbitration in the cloud, impossibility results on distributing the Arbiter, and keeping the user passwords safe (joint work at Microsoft Research). I will also be available to talk on these other projects after the presentation.

Olle Segerdahl - DOMXSS is not Dead - SecurityFest 2019
 
53:28
DOMXSS is definitely still "a thing" on the Internet and can be hard to detect, especially if buried in third party JS libraries or under 4 layers of JQuery abstractions. The publicly available tools to detect DOMXSS don't seem to have evolved much since DOMinator in 2011 and can be difficult to use in a real-world testing scenario. A weekend project of mine investigating in-browser JS taint analysis turned into a "good enough" tool that quickly found a vulnerability in a third-party service used by hundreds of thousands of websites. This tool will be demonstrated and released as open source for the community to build on. About Olle Segerdahl Olle Segerdahl Olle is a veteran of the IT-security industry, having worked with both “breaking” and “building” security solutions for over 20 years. During that time, he has worked on securing classified systems, critical infrastructure and cryptographic products as well as building software whitelisting solutions used by industrial robots and medical equipment. He is currently a Principal Consultant in F-Secure’s technical security consulting practice.

Saving the elephant—now, not later
 
43:26
Big data security challenges are bit different from traditional client-server applications and are distributed in nature, introducing unique security vulnerabilities. Cloud Security Alliance (CSA) has categorized the different security and privacy challenges into four different aspects of the big data ecosystem. These aspects are infrastructure security, data privacy, data management and, integrity and reactive security. Each of these aspects are further divided into following security challenges: 1. Infrastructure security a. Secure distributed processing of data b. Security best practices for non-relational data stores 2. Data privacy a. Privacy-preserving analytics b. Cryptographic technologies for big data c. Granular access control 3. Data management a. Secure data storage and transaction logs b. Granular audits c. Data provenance 4. Integrity and reactive security a. Endpoint input validation/filtering b. Real-time security/compliance monitoring In this talk, we are going to refer above classification and identify existing security controls, best practices, and guidelines. We will also paint a big picture about how collective usage of all discussed security controls (Kerberos, TDE, LDAP, SSO, SSL/TLS, Apache Knox, Apache Ranger, Apache Atlas, Ambari Infra, etc.) can address fundamental security and privacy challenges that encompass the entire Hadoop ecosystem. We will also discuss briefly recent security incidents involving Hadoop systems. Speakers KRISHNA PANDEY Staff Software Engineer Hortonworks KUNAL RAJGURU Premier Support Enginner Hortonworks

What is SIDE-CHANNEL ATTACK? What does SIDE-CHANNEL ATTACK mean? SIDE-CHANNEL ATTACK meaning
 
07:01
What is SIDE-CHANNEL ATTACK? What does SIDE-CHANNEL ATTACK mean? SIDE-CHANNEL ATTACK meaning - SIDE-CHANNEL ATTACK definition - SIDE-CHANNEL 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 cryptography, a side-channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information, which can be exploited to break the system. Some side-channel attacks require technical knowledge of the internal operation of the system on which the cryptography is implemented, although others such as differential power analysis are effective as black-box attacks. Many powerful side-channel attacks are based on statistical methods pioneered by Paul Kocher. Attempts to break a cryptosystem by deceiving or coercing people with legitimate access are not typically called side-channel attacks: see social engineering and rubber-hose cryptanalysis. For attacks on computer systems themselves (which are often used to perform cryptography and thus contain cryptographic keys or plaintexts), see computer security. The rise of Web 2.0 applications and software-as-a-service has also significantly raised the possibility of side-channel attacks on the web, even when transmissions between a web browser and server are encrypted (e.g., through HTTPS or WiFi encryption), according to researchers from Microsoft Research and Indiana University. General classes of side channel attack include: Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations take to perform. Power-monitoring attack — attacks that make use of varying power consumption by the hardware during computation. Electromagnetic attack — attacks based on leaked electromagnetic radiation, which can directly provide plaintexts and other information. Such measurements can be used to infer cryptographic keys using techniques equivalent to those in power analysis or can be used in non-cryptographic attacks, e.g. TEMPEST (aka van Eck phreaking or radiation monitoring) attacks. Acoustic cryptanalysis — attacks that exploit sound produced during a computation (rather like power analysis). Differential fault analysis — in which secrets are discovered by introducing faults in a computation. Data remanence — in which sensitive data are read after supposedly having been deleted. Row hammer — in which off-limits memory can be changed by accessing adjacent memory. Optical - in which secrets and sensitive data can be read by visual recording using a high resolution camera, or other devices that have such capabilities (see examples below). In all cases, the underlying principle is that physical effects caused by the operation of a cryptosystem (on the side) can provide useful extra information about secrets in the system, for example, the cryptographic key, partial state information, full or partial plaintexts and so forth. The term cryptophthora (secret degradation) is sometimes used to express the degradation of secret key material resulting from side-channel leakage. A cache side-channel attack works by monitoring security critical operations such as AES T-table entry or modular exponentiation multiplicand accesses. Attacker then is able to recover the secret key depending on the accesses made (or not made) by the victim, deducing the encryption key. Also, unlike some of the other side-channel attacks, this method does not create a fault in the ongoing cryptographic operation and is invisible to the victim.

DEF CON 25 - Luke Young - There’s no place like 127.001: Achieving reliable DNS rebinding
 
41:32
Most people lock their doors at night, however if you walk into someone's home you likely won't find every piece of furniture bolted to the floor as well. We trust that if someone is inside our home they are supposed to be there. Unfortunately many developers treat local networks just the same, assuming all internal HTTP traffic is trusted, however this is not always the case. They incorrectly assume that their services will be protected by the same-origin policy in browsers, rather than implementing proper authentication mechanisms. By abusing this implicit trust we can gain access to confidential data and internal services which are not intended to be publicly accessible. I will demonstrate that this is a poor security control and can be trivially bypassed via an older technique, DNS rebinding. The talk will cover how DNS rebinding works, the mitigations imposed by modern browsers and networks, and how each mitigation can be bypassed. I will discuss the notorious unreliability of DNS rebinding attacks that causes many developers to ignore the issue and how to overcome this unreliability. Finally, I will examine a variety of popular services and tools to understand how they are affected by DNS rebinding. I will be releasing a tool that allows researchers to automate DNS rebinding attacks, the associated mitigation bypasses and generate drop-dead simple proof-of-concept exploits. I will demonstrate this tool by developing exploits for each vulnerable service, ending the talk by exploiting a vulnerable service to obtain remote-code execution, live.

Keynote - Dr Muriel Médard at SAI Conference 2015 - Stormy Clouds - security in cloud systems
 
52:43
This video was recorded at SAI Conference 2015 - http://saiconference.com/Computing Abstract: As massively distributed storage becomes the norm in cloud networks, they contend with new vulnerabilities imputed by the presence of data in different, possibly untrusted nodes. In this talk, we consider two such types of vulnerabilities. The first one is the risk posed to data stored at nodes that are untrusted. We show that coding alone can be substituted to encryption, with coded portions of data in trusted nodes acting as keys for coded data in untrusted ones. In general, we may interpret keys as representing the size of the list over which an adversary would need to generate guesses in order to recover the plaintext, leading to a natural connection between list decoding and secrecy. Under such a model, we show that algebraic block maximum distance separable (MDS) codes can be constructed so that lists satisfy certain secrecy criteria, which we define to generalize common perfect secrecy and weak secrecy notions. The second type of vulnerability concerns the risk of passwords’ being guessed over some nodes storing data, as illustrated by recent cloud attacks. In this domain, the use of guesswork as metric shows that the dominant effect on vulnerability is not necessarily from a single node, but that it varies in time according to the number of guesses issued. We also introduce the notion of inscrutability, as the growth rate of the average number of probes that an attacker has to make, one at a time, using his best strategy, until he can correctly guess one or more secret strings from multiple randomly chosen strings. About the Speaker: Muriel Médard is the Cecil E. Green Professor of the Electrical Engineering and Computer Science Department at MIT.

[CB16] Air-Gap security by Mordechai Guri, Yisroel Mirsky, Yuval Elovici.
 
47:58
[CB16] Air-Gap security: State-of-the-art Attacks, Analysis, and Mitigation by by Mordechai Guri, Yisroel Mirsky, Yuval Elovici. Air-gapped networks are isolated, separated both logically and physically from public networks. For example, military, industrial, and financial networks. Although the feasibility of invading such systems has been demonstrated in recent years, communication of data to/from air-gapped networks is a challenging task to attackers to perpetrate, an even more difficult threat to defend against. New methods of communicating with air gapped networks are currently being exposed, some advanced and difficult to mitigate. These new found vulnerabilities have wide reaching implications on what we considered to be a foolproof solution to network security –the placement of a physical air gap. But it doesn’t stop there – new techniques of covertly getting information in and out of air gapped networks are being exposed. Thus it is important not only to publicize these vectors of attack, but their countermeasures and feasibility as well. In this talk, we will outline the steps an attacker must take in order to bridge an air gapped network. We will review the state-of-the-art techniques over thermal, radio, and acoustic channels, and discuss each one’s countermeasures and feasibility. Most of techniques in this talk were discovered in our labs by researcher Mordichai Guri under the supervision of Prof. Yuval Elovici. -- Mordechai Guri Mordechai Guri is an accomplished computer scientist and security expert with over 20 years of practical research experience. He earned his Bsc and Msc Suma Cum Laude, from the computer science department at the Hebrew University of Jerusalem.

He manages academic research in various aspects of cyber-security to the commercial and governmental sectors. In the past few years Mordechai has led a number of breakthrough research projects in cyber-security, some of them have been published worldwide. His research focuses on state-of-the-art challenges in the field of cyber-attack and cyber-defense. Mordechai examines current paradigms and develops new methods for improved mitigation of security problems in the modern cyber environment. His research topics include OS security, advanced malware, Moving Target Defense (MTD), mobile security and embedded systems.

USENIX Security '17 - Hacking in Darkness: Return-oriented Programming against Secure Enclaves
 
32:47
Jaehyuk Lee and Jinsoo Jang, KAIST; Yeongjin Jang, Georgia Institute of Technology; Nohyun Kwak, Yeseul Choi, and Changho Choi, KAIST; Taesoo Kim, Georgia Institute of Technology; Marcus Peinado, Microsoft Research; Brent Byunghoon Kang, KAIST Intel Software Guard Extensions (SGX) is a hardware-based Trusted Execution Environment (TEE) that is widely seen as a promising solution to traditional security threats. While SGX promises strong protection to bug-free software, decades of experience show that we have to expect vulnerabilities in any non-trivial application. In a traditional environment, such vulnerabilities often allow attackers to take complete control of vulnerable systems. Efforts to evaluate the security of SGX have focused on side-channels. So far, neither a practical attack against a vulnerability in enclave code nor a proof-of-concept attack scenario has been demonstrated. Thus, a fundamental question remains: What are the consequences and dangers of having a memory corruption vulnerability in enclave code? To answer this question, we comprehensively analyze exploitation techniques against vulnerabilities inside enclaves. We demonstrate a practical exploitation technique, called Dark-ROP, which can completely disarm the security guarantees of SGX. Dark-ROP exploits a memory corruption vulnerability in the enclave software through return-oriented programming (ROP). However Dark-ROP differs significantly from traditional ROP attacks because the target code runs under solid hardware protection. We overcome the problem of exploiting SGX-specific properties and obstacles by formulating a novel ROP attack scheme against SGX under practical assumptions. Specifically, we build several oracles that inform the attacker about the status of enclave execution. This enables him to launch the ROP attack while both code and data are hidden. In addition, we exfiltrate the enclave’s code and data into a shadow application to fully control the execution environment. This shadow application emulates the enclave under the complete control of the attacker, using the enclave (through ROP calls) only to perform SGX operations such as reading the enclave’s SGX crypto keys. The consequences of Dark-ROP are alarming; the attacker can completely breach the enclave’s memory protections and trick the SGX hardware into disclosing the enclave’s encryption keys and producing measurement reports that defeat remote attestation. This result strongly suggests that SGX research should focus more on traditional security mitigations rather than on making enclave development more convenient by expanding the trusted computing base and the attack surface (e.g., Graphene, Haven).
