Cybercriminal Checklist Review: Password Theft Tactics & PtH Attacks
 
01:26:03
Featuring guest speaker, hacker, enterprise security MVP, and named by SC Magazine as one of the top "Women to Watch” in security, Paula Januszkiewicz. When we set up our Windows server or workstation passwords, they are hashed and stored either in SAM or a ntds.dit database in Active Directory. This is useful for verification purposes, but if your operating system can re-use the password, it means others can decrypt it! A cached hash may also be reused later for authentication. In this engaging on-demand webinar, Enterprise Security MVP and Microsoft Security Trusted Advisor, Paula Januszkiewicz will delve into: -How PtH attacks work, and how to prevent them -How to prevent password credential leakage in Windows -How credential attacks work -The role of cryptography for passwords in Windows -The DPAPI (Data Protection API) idea behind the cached credentials Tune in to gain deep insights into pervasive encryption and decryption techniques used across systems, networks, and applications; and how to strengthen your Windows password security!

MCTS 70-680: Encrypting File System (EFS)
 
15:17
The Encrypting File System (EFS) is used in Windows to encrypt files so they cannot be read even using an offline attack. In order to ensure you can always access encrypted files, Windows allows a DRA to be created. A DRA is anther user that can access any files encrypted. This video looks at how the encrypted file system works and how to configure a DRA. 03:11 demo on how to encrypt files 05:52 exporting the EFS certificate using cipher /r:filename 06:22 Configuring a DRA using group policy HKEY\Computer configuration\Windows Settings\Security Settings\Public Key Polices\Encrypting file system How EFS works A file is encrypted with a symmetric key. This is the same style of algorithm used to secure compressed files like zip. The same password or key is used to encrypt the file as decrypt the file. The symmetric key is randomized for each file and thus you need some where to store all these symmetric keys. The easiest place to store the symmetric key is in the file itself. That way if the file is moved to a different computer or hard disk the key is always present with the file. In order to make sure that the symmetric key is stored in the file can't be read, the symmetric key is encrypted using an EFS certificate. An EFS certificate is generated for the user when they encrypt there first file or by running the command cipher /k. In a domain environment you can also configure a certificate authority to create and manage these certificates. This essentially means the certificates are generated by Active Directory and store in Active Directory. A certificate uses asymmetric keys. Asymmetric keys are when you have two keys. One key to encrypt the file and one to decrypt the file. Neither key will perform both functions. This means that when the symmetric key is encrypted with the public key it can be read without the private key. This protects the symmetric key. In order to protect the EFS certificate stored on the computer it is encrypted using the users password. When the users logs on the users password is used to access the certificate and thus get access to the private keys in the certificate. This is why when changing the users password you should always be logged in as the user. This way Windows can access the EFS certificate and change the password. If you are logged in as anther user and you use the administrators tools to change the password the password will not be updated on the EFS certificate and access to the EFS certificate will be lost. In order to ensure you can always access encrypted files you can firstly backup your EFS certificates. Secondly you can configure a DRA. A DRA is anther user that has access to the encrypted files. EFS does this by adding another symmetric key to the file which is encrypted using the DRA's EFS public key. Setting up a DRA A DRA is anther user that has access to encrypted files. The DRA will only be able to access files that were encrypted after it was setup. In order to configure a DRA the certificate for the DRA user must be exported using the command cipher /r:filename. Once the cer and pfk files are exported, the certificates public key (cer file) can be added to the "HKEY\Computer configuration\Windows Settings\Security Settings\Public Key Polices\Encrypting file system". In order to read encrypted files, the pfk file needs to be added to the computer you want to read the files on. This case is done by double clicking the pfk file and finishing the wizard.

Practical Attacks on Crypto Structures The SSL/TLS Case  Itsik Mantin Technion Lecture
 
54:40
Practical Attacks on Crypto Structures The SSL/TLS Case - Itsik Mantin of Imperva at Technion-Israel Institute of Technology Technion Computer Engineering Center summer school 2014 Lecture The Secure Socket Layer SSL and its successor Transport Layer Security TLS are probably the most popular cryptographic protocols in the world. Over the last decade, a large number of attacks were discovered on TLS, showing practical ways to break the protocol and impersonate legitimate servers or steal secret data. As opposed to most attacks on popular systems, many of the TLS attacks broke the cryptographic structures of the protocol, including the way it uses the Advanced Encryption Standard AES. In the presentation I will explain how the BEAST, TIME, BREACH and other attacks work, and will try to answer the questions that bother many people in the web industry: 1 Why does TLS have so many vulnerabilities, and 2Should we expect more attacks to come.

Kali Linux | How to Encrypt All Your Network Traffic using tcpcryptd
 
06:14
In this video, I show you how to encrypt your network traffic using a cool tool called tcpcrypt and kali linux 2016.2 Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. Unlike other security mechanisms, Tcpcrypt works out of the box: it requires no configuration, no changes to applications, and your network connections will continue to work even if the remote end does not support Tcpcrypt, in which case connections will gracefully fall back to standard clear-text TCP. Install Tcpcrypt and you’ll feel no difference in your every day user experience, but yet your traffic will be more secure and you’ll have made life much harder for hackers. tcpcrypt: https://github.com/scslab/tcpcrypt So why is now the right time to turn on encryption? Here are some reasons: Intercepting communications today is simpler than ever because of wireless networks. Ask a hacker how many e-mail passwords can be intercepted at an airport by just using a wifi-enabled laptop. This unsophisticated attack is in reach of many. The times when only a few elite had the necessary skill to eavesdrop are gone. Computers have now become fast enough to encrypt all Internet traffic. New computers come with special hardware crypto instructions that allow encrypted networking speeds of 10Gbit/s. How many of us even achieve those speeds on the Internet or would want to download (and watch) one movie per second? Clearly, we can encrypt fast enough. Research advances and the lessons learnt from over 10 years of experience with the web finally enabled us to design a protocol that can be used in today’s Internet, by today’s users. Our protocol is pragmatic: it requires no changes to applications, it works with NATs (i.e., compatible with your DSL router), and will work even if the other end has not yet upgraded to tcpcrypt—in which case it will gracefully fall back to using the old plain-text TCP. No user configuration is required, making it accessible to lay users—no more obscure requests like “Please generate a 2048-bit RSA-3 key and a certificate request for signing by a CA”. Tcpcrypt can be incrementally deployed today, and with time the whole Internet will become encrypted. How Tcpcrypt works Tcpcrypt is opportunistic encryption. If the other end speaks Tcpcrypt, then your traffic will be encrypted; otherwise it will be in clear text. Thus, Tcpcrypt alone provides no guarantees—it is best effort. If, however, a Tcpcrypt connection is successful and any attackers that exist are passive, then Tcpcrypt guarantees privacy. Network attackers come in two varieties: passive and active (man-in-the-middle). Passive attacks are much simpler to execute because they just require listening on the network. Active attacks are much harder as they require listening and modifying network traffic, often requiring very precise timing that can make some attacks impractical. By default Tcpcrypt is vulnerable to active attacks—an attacker can, for example, modify a server’s response to say that Tcpcrypt is not supported (when in fact it is) so that all subsequent traffic will be clear text and can thus be eavesdropped on. Tcpcrypt, however, is powerful enough to stop active attacks, too, if the application using it performs authentication. For example, if you log in to online banking using a password and the connection is over Tcpcrypt, it is possible to use that shared secret between you and the bank (i.e., the password) to authenticate that you are actually speaking to the bank and not some active (man-in-the-middle) attacker. The attacker cannot spoof authentication as it lacks the password. Thus, by default, Tcpcrypt will try its best to protect your traffic. Applications requiring stricter guarantees can get them by authenticating a Tcpcrypt session.

Pass the Hash Attacks: 15 minute crash course from Thycotic
 
12:17
Join Jonathan Cogley, CEO at Thycotic, for a crash course in Pass the Hash attacks. Find out how these attacks happen, ways newer versions of Windows help protect against them, and other steps you can take to protect your organization. Pass the Hash is a very popular attack that takes just minutes to escalate. When successful, an attacker can capture a password hash for a domain admin account instantly. Once the hash is compromised, it can be used to move horizontally across the network, giving the attacker access to whatever that credential unlocks. A privileged account management (PAM) tool like Thycotic Secret Server helps you manage passwords, keeps them securely encrypted, audits who uses them, and automatically changes the passwords after a credential is used. When a PAM tool automates password management, it guarantees passwords are changed after use and ensures password hashes are no longer valid, even if they were captured by an attacker. Protect yourself against Pass-the-Hash attacks using a privileged account management tool like Thycotic's Secret Server at: http://thycotic.com/solutions/pass-the-hash-att­­acks Recorded live at Microsoft Ignite 2015.

HTTP Cookie Hijacking in the Wild: Security and Privacy Implications
 
46:12
by Suphannee Sivakorn & Jason Polakis The widespread demand for online privacy, also fueled by widely-publicized demonstrations of session hijacking attacks against popular websites (see Firesheep), has spearheaded the increasing deployment of HTTPS. However, many websites still avoid ubiquitous encryption due to performance or compatibility issues. The prevailing approach in these cases is to force critical functionality and sensitive data access over encrypted connections, while allowing more innocuous functionality to be accessed over HTTP. In practice, this approach is prone to flaws that can expose sensitive information or functionality to third parties. In this work, we conduct an in-depth assessment of a diverse set of major websites and explore what functionality and information is exposed to attackers that have hijacked a user's HTTP cookies. We identify a recurring pattern across websites with partially deployed HTTPS; service personalization inadvertently results in the exposure of private information. The separation of functionality across multiple cookies with different scopes and inter-dependencies further complicates matters, as imprecise access control renders restricted account functionality accessible to non-session cookies. Our cookie hijacking study reveals a number of severe flaws; attackers can obtain the user's home and work address and visited websites from Google, Bing and Baidu expose the user's complete search history, and Yahoo allows attackers to extract the contact list and send emails from the user's account. Furthermore, e-commerce vendors such as Amazon and Ebay expose the user's purchase history (partial and full respectively), and almost every website exposes the user's name and email address. Ad networks like Doubleclick can also reveal pages the user has visited. To fully evaluate the practicality and extent of cookie hijacking, we explore multiple aspects of the online ecosystem, including mobile apps, browser security mechanisms, extensions and search bars. To estimate the extent of the threat, we run IRB-approved measurements on a subset of our university's public wireless network for 30 days, and detect over 282K accounts exposing the cookies required for our hijacking attacks. We also explore how users can protect themselves and find that, while mechanisms such as the EFF's HTTPS Everywhere extension can reduce the attack surface, HTTP cookies are still regularly exposed. The privacy implications of these attacks become even more alarming when considering how they can be used to deanonymize Tor users. Our measurements suggest that a significant portion of Tor users may currently be vulnerable to cookie hijacking.

DEF CON 23 - Eijah - Crypto for Hackers
 
55:52
Hacking is hard. It takes passion, dedication, and an unwavering attention to detail. Hacking requires a breadth of knowledge spread across many domains. We need to have experience with different platforms, operating systems, software packages, tools, programming languages, and technology trends. Being overly deficient in any one of these areas can add hours to our hack, or even worse, bring us total failure. And while all of these things are important for a well-rounded hacker, one of the key areas that is often overlooked is cryptography. In an era dominated by security breaches, an understanding of encryption and hashing algorithms provides a tremendous advantage. We can better hone our attack vectors, especially when looking for security holes. A few years ago I released the first Blu-Ray device key, AA856A1BA814AB99FFDEBA6AEFBE1C04, by exploiting a vulnerability in an implementation of the AACS protocol. As hacks go, it was a simple one. But it was the knowledge of crypto that made it all possible. This presentation is an overview of the most common crypto routines helpful to hackers. We'll review the strengths and weaknesses of each algorithm, which ones to embrace, and which ones to avoid. You'll get C++ code examples, high-level wrapper classes, and an open-source library that implements all the algorithms. We'll even talk about creative ways to merge algorithms to further increase entropy and key strength. If you've ever wanted to learn how crypto can give you an advantage as a hacker, then this talk is for you. With this information you'll be able to maximize your hacks and better protect your personal data.

Full Disk Operating System Encryption Softwares in India/ Laptops / PC/  Computers
 
07:30
DriveCrypt Plus Pack (DCPP) encrypts the entire operating system, partitions or the entire hard disk using AES 256. DCPP file encryption software is automatic and completely transparent to the user. Not only does this decrease user involvement and training requirements, but also it creates the foundation for enforceable security. The careful integration of boot protection and automatic encryption provides a high degree of security with minimal impact on users. Boot protection prevents subversion of the operating system (via CD/USB boot-up, for example) or the introduction of rogue programs while sector by sector encryption makes it impossible to copy individual files for brute force attacks. DCPP Windows encryption safeguards the operating system and the important system files (which often contain clues to passwords for Windows). DCPP can create a fake “prepared” operating system: If somebody forces you to reveal the Password, you can provide a "second password" and the system will boot the prepared/fake operating system. The adversary will not be able to determine if he is using the fake or real system. Alternatively, if you are forced to reveal a password, the “destruction password” can be used to irremediably destroy all data. As data is read from the hard disk, DCPP automatically decrypts the data before it is loaded into memory. When data is written back to the hard disk, it is automatically re-encrypted. This process is completely transparent to the user or any application programs, the data is caught "on the fly" as it transfers back and forth between the hard disk and memory. Consequently, users don't need to remember to decrypt or re-encrypt their data, or change the normal operation of their PC. In addition, only individual sectors are decrypted at any one time, not the whole hard disk. Some other products that claim to be "on the fly" decrypt an entire file and load it into memory, creating significant security risks. DCPP is smarter and more secure because it decrypts only the specific sectors of a file that are in use. Unprotected data never resides on a DCPP encrypted disk. The user is authenticated by means of pre-boot authentication (PBA) before the system is started and therefore before the operating system is booted. This kind of authentication cannot be manipulated, PBA therefore guarantees maximum security. Neither keys nor passwords are stored on the PC's hard disk. All of the information required to boot the operating system is derived from the password. This makes the use of hard disk tools for analysing the hard disk completely ineffective. PBA in provided by a system call BootAuth and is a fully graphical login screen. Automatic & transparent Full Disk Encryption (FDE) offers several key advantages relative to file encryption. FDE secures the system and temp files that often contain sensitive data but are missed by file encryption. Even removing the drive itself does not give access to any file or directory structure. FDE is performed sector by sector without creating temp or backup files. As a result, large files will decrypt without delay whereas file encryption is normally much slower. Whole disk encryption also avoids such time consuming tasks as secure deletes of temp files or work files in clear text, and obviates the need to do a full delete on disks to be discarded. Boot protection Pre-Boot authentication: Login before starting the operating system Multiple OS boot support (Microsoft) Invisible operating system (allows the hiding of the entire operating system) Full or partial hard disk encryption Sector level protection Complete "power off" protection i.e. unauthorised users are prohibited from starting up the PC AES 256 bit encryption No size limitation for encrypted disks Manages an unlimited amount of encrypted disks simultaneously. Allows steganography to hide data into pictures Trojan and keyboard sniffer protection preventing passwords from being sniffed/captured (red screen modus). Anti dictionary and brute-force attack mechanisms (due to the nature of DCPP, it is the most difficult system to attack compared to anything else available.) Encrypts almost any kind of media (hard disks, floppy disks, ZIP, JAZ, etc...) Administrator/user specific rights USB-Token authentication at pre-boot level (Aladdin R2, Rainbow USB-Token as well as Memorysticks) Facility to validate the integrity of the encryption method. Recovery disk for "disaster recovery" Easy to install, deploy and use. Completely transparent to the user Minimal administration and user training.

Behind the Scenes of iOS Security
 
51:32
by Ivan Krstic With over a billion active devices and in-depth security protections spanning every layer from silicon to software, Apple works to advance the state of the art in mobile security with every release of iOS. We will discuss three iOS security mechanisms in unprecedented technical detail, offering the first public discussion of one of them new to iOS 10. HomeKit, Auto Unlock and iCloud Keychain are three Apple technologies that handle exceptionally sensitive user data – controlling devices (including locks) in the user's home, the ability to unlock a user's Mac from an Apple Watch, and the user's passwords and credit card information, respectively. We will discuss the cryptographic design and implementation of our novel secure synchronization fabric which moves confidential data between devices without exposing it to Apple, while affording the user the ability to recover data in case of device loss. Data Protection is the cryptographic system protecting user data on all iOS devices. We will discuss the Secure Enclave Processor present in iPhone 5S and later devices and explain how it enabled a new approach to Data Protection key derivation and brute force rate limiting within a small TCB, making no intermediate or derived keys available to the normal Application Processor. Traditional browser-based vulnerabilities are becoming harder to exploit due to increasingly sophisticated mitigation techniques. We will discuss a unique JIT hardening mechanism in iOS 10 that makes the iOS Safari JIT a more difficult target.

Combining Cryptographic Primitives To Prevent Jamming Attacks In Wireless Networks
 
05:49
Objective of this project is to prevent jamming attacks in wireless network using cryptographic primitives. The Open Nature of wireless medium leaves an intentional interference attack, typically referred to as jamming. This intentional interference with wireless transmission launch pad for mounting Denial-Of-Service attack on wireless networks. Typically, jamming has been addresses under an external threat model. However, adversaries with internal knowledge of protocol specification and network secrets can launch low-effort jamming attacks that are difficult to detect and counter. In this work we address the problem of jamming attacks and adversary is active for short period of time, selectively targeting the messages of high importance. We show that the selective jamming attacks can be launched by performing real-time packet classification at the physical layer. To mitigate these attacks, we develop three schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layer attributes. They are Strong Hiding Commitment Schemes (SHCS), Cryptographic Puzzles Hiding Schemes (CPHS), All-Or-Nothing Transformation Hiding Schemes (AONTS-HS). Random key distribution methods are done along with three schemes to give more secured packet transmission in wireless networks.BAVITHRA VM5446 IT BATCH.44

Bitlocker Encryption
 
04:05
- Windows BitLocker Drive Encryption is a new security feature that provides better data protection for your computer, by encrypting all data stored on the Windows operating system volume. (In this version of Windows, a volume consists of one or more partitions on one or more hard disks. BitLocker works with simple volumes, where one volume is one partition. A volume usually has a drive letter assigned, such as "C.") - BitLocker protects your hard drive from offline attack. This is the type of attack where a malicious user will take the hard drive from your mobile machine and connect it to another machine so they can harvest your data. BitLocker also protects your data if a malicious user boots from an alternate Operating System. With either attack method, BitLocker encrypts the hard drive so that when someone has physical access to the drive, the drive is unreadable. -BitLocker lets you encrypt the hard drive(s) on your windows 10 (pro and enterprise), windows 8.1 and 8.0 (pro and enterprise), Windows 7 and Vista Enterprise, Windows 7 and Vista Ultimate or Windows Server 2008 and R2. BitLocker will not encrypt hard drives for Windows XP, Windows 2000 or Windows 2003 - Enjoy.. and more at http://www.shibiaprime.blogspot.com
