Android ransomware: turning CryptoLocker into CryptoUnlocker
 
31:15
This presentation by Alexander Adamov (NioGuard) was delivered at VB2015 in Prague, Czech Republic. We are seeing an increasing number of pieces of ransomware for Android devices. They are adopting new social engineering, communication and encryption techniques such as the use of TOR and advanced encryption algorithms (RSA-1024 and even elliptic curve cryptography). However, the majority of Android cryptolockers are simple enough to be disassembled and used to restore encrypted data. The presentation will start with an overview of recent Android ransomware as well as the technologies used by them. Then we turn to reverse engineering techniques that can be applied to analyse malicious behaviour. Finally, we will perform a demo showing the process of analysing and patching the cyptolocker. During the demo the following tools and techniques will be addressed: disassembling/assembling using apktool, decompiling a dex file to jar with the dex2jar tool, decompiling a jar file with Java Decompiler to analyse the original Java code, a signing tool to sign the new package, Android SDK and emulator to run the cryptolocker.

How to remove Cryptolocker-v3(TeslaCrypt/Alpha .Crypt) ransomware
 
03:15
Cryptolocker-v3(TeslaCrypt/Alpha Crypt) is a file-encrypting ransomware programs that target all version of Windows including Windows XP, Windows Vista, Windows 7, and Windows 8. When Cryptolocker-v3 first installed on your computer they will create a random named executable in the %AppData% folder. It important to stress that both Cryptolocker-v3, TeslaCrypt and Alpha Crypt will scan all drive letters on your computer including removable drives, network shares, and even DropBox mappings. If a supported data file is detected it will encrypt it and then append a .ECC or .EZZ extension to the filename based on the particular variant you are infected with. The Cryptolocker-v3 ransomware will change your Windows desktop wallpaper to a BMP file located on the Windows desktop. And there are some fiels: HELP_TO_DECRYPT_YOUR_FILES.txt and the BMP file is called HELP_TO_DECRYPT_YOUR_FILES.bmp or HELP_TO_SAVE_FILES.txt and HELP_TO_SAVE_FILES.bmp. The Cryptolocker-v3 prompted "Your personal files are encrypted", and need a ransom of $500 worth of bitcoins in order to obtain the key to decrypt the files. TeslaCrypt and Alpha Crypt appeared earlier this year and masquerades as a variant of the notorious CryptoLocker ransomware. How to remove Cryptolocker-v3, TeslaCrypt or Alpha Crypt ransomware virus? 1. Reboot your computer into Safe Mode. 2. Remove associated Cryptolocker-v3 Files: %AppData%\random.exe %AppData%\key.dat %AppData%\log.html 3. Remove associated Cryptolocker-v3 Registry Information: HKCU\Software\Microsoft\Windows\CurrentVersion\Run\%AppData%\random.exe Is it possible to decrypt files encrypted by Alpha Crypt? Unfortunately at this time there is no way to decrypt. Learn more about how to remove computer virus ►https://www.youtube.com/user/MrRemoveVirus

My PGP/GPG key is RSA 2048-bit, but I put the private key on Gnuk Token
 
45:05
NIIBE Yutaka https://summit.debconf.org/debconf14/meeting/144/my-pgpgpg-key-is-rsa-2048-bit-but-i-put-the-private-key-on-gnuk-token/ In this casual session, I will demonstrate Gnuk Token, which is built by Free Software and free hardware design. I will demonstrate NeuG standalone device, which can generate random numbers at 70KiB/s, too. My PGP/GPG key is RSA 2048-bit now. I understand that some person doesn't want to sign my key, because it looks weaker. I develop Gnuk, the firmware for USB Token, which is compatible to OpenPGP card, under GPLv3. My original purpose/goal was not to put a person into a dilemma: computing freedom vs. better security. I think that I have achieved the goal somehow, and it's strong enough (RSA 2048-bit) and it's not that slow (1.4sec to sign), IMO. It is unfortunate for me that Debian community demands RSA 4096-bit or more. Thus, another dilemma is still there; longer key length or better control of private key by Free Software. Good news is that I have implemented Ed25519 (for signing) already, and going to implement Curve25519 (for decryption) in Gnuk. Besides, I am also GnuPG developer, and try to implement Curve25519 support now. It will be good if GnuPG 2.1 will be released and people will enjoy Gnuk Token with Ed25519/Curve25519 until Debconf15 in Germany. During the development of Gnuk, I develop NeuG, the true random number generator to generate private keys on the device. The entropy source is built-in A/D converter. I realized that this feature is very useful, and I build standalone device (just for generating random numbers). FST-01 is a reference board for Gnuk/NeuG. It has STM32F103 as MCU which runs at 72MHz. It has no crypto accelerator. Schematic design and PCB design are available as free hardware design. Material is available at gobby.debian.org: debconf14 → bof → gnuk

What is CRYPTOGRAPHIC SERVICE PROVIDER? What does CRYPTOGRAPHIC SERVICE PROVIDER mean?

What is CRYPTOGRAPHIC SERVICE PROVIDER? What does CRYPTOGRAPHIC SERVICE PROVIDER mean? CRYPTOGRAPHIC SERVICE PROVIDER meaning - CRYPTOGRAPHIC SERVICE PROVIDER definition - CRYPTOGRAPHIC SERVICE PROVIDER 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 Microsoft Windows, a Cryptographic Service Provider (CSP) is a software library that implements the Microsoft CryptoAPI (CAPI). CSPs implement encoding and decoding functions, which computer application programs may use, for example, to implement strong user authentication or for secure email. CSPs are independent modules that can be used by different applications. A user program calls CryptoAPI functions and these are redirected to CSPs functions. Since CSPs are responsible for implementing cryptographic algorithms and standards, applications do not need to be concerned about security details. Furthermore, one application can define which CSP it is going to use on its calls to CryptoAPI. In fact, all cryptographic activity is implemented in CSPs. CryptoAPI only works as a bridge between the application and the CSP. CSPs are implemented basically as a special type of DLL with special restrictions on loading and use. Every CSP must be digitally signed by Microsoft and the signature is verified when Windows loads the CSP. In addition, after being loaded, Windows periodically re-scans the CSP to detect tampering, either by malicious software such as computer viruses or by the user him/herself trying to circumvent restrictions (for example on cryptographic key length) that might be built into the CSP's code. To obtain a signature, non-Microsoft CSP developers must supply paperwork to Microsoft promising to obey various legal restrictions and giving valid contact information. As of circa 2000, Microsoft did not charge any fees to supply these signatures. For development and testing purposes, a CSP developer can configure Windows to recognize the developer's own signatures instead of Microsoft's, but this is a somewhat complex and obscure operation unsuitable for nontechnical end users. The CAPI/CSP architecture had its origins in the era of restrictive US government controls on the export of cryptography. Microsoft's default or "base" CSP then included with Windows was limited to 512-bit RSA public-key cryptography and 40-bit symmetric cryptography, the maximum key lengths permitted in exportable mass market software at the time. CSPs implementing stronger cryptography were available only to U.S. residents, unless the CSPs themselves had received U.S. government export approval. The system of requiring CSPs to be signed only on presentation of completed paperwork was intended to prevent the easy spread of unauthorized CSPs implemented by anonymous or foreign developers. As such, it was presented as a concession made by Microsoft to the government, in order to get export approval for the CAPI itself. After the Bernstein v. United States court decision establishing computer source code as protected free speech and the transfer of cryptographic regulatory authority from the U.S. State Department to the more pro-export Commerce Department, the restrictions on key lengths were dropped, and the CSPs shipped with Windows now include full-strength cryptography. The main use of third-party CSPs is to interface with external cryptography hardware such as hardware security modules (HSM) or smart cards.

What is a trapdoor function?
 
04:06
Modern cryptography depends on the existence of several special kinds of mathematical functions. One important kind is a trapdoor function. Trapdoor functions are somewhat similar to hash functions in that they are easy to compute but hard to invert…​ except if you know a secret piece of information. So if someone does not have the secret or key, they cannot invert the function. If they do, they can open the trapdoor and invert the function. Trapdoor functions form the basis of modern cryptographic techniques that are widely-used online.

Your driving license to expert cryptography
 
01:13:59
http://www.wibu.com/webinar-your-driving-license-to-expert-cryptography.html - Download the slide deck Few successful software applications don’t use cryptographic methods to protect code and data from predatory attacks. By analogy, applying cryptography is like driving a car. Just as you first have to learn what all the controls are for before you can go zipping down the interstate, first you must become familiar with basic cryptographic methods. And just like yesterday’s trendy car is no longer in vogue today, obsolescence in security is accelerating. There isn’t much you can do to slow down technological evolution, but as a software developer, you can ensure that a primary responsibility is to use cryptography properly and safely. CodeMeter® from Wibu-Systems offers a wide range of cryptographic methods. Nevertheless, even great technologies like CodeMeter may fail if they have been implemented poorly or without the necessary safety precautions. The presentation provides an overview of the available cryptographic methods in the CodeMeter API. An essential key point is the secure storage of private and secret keys; the first question you should ask yourself is where you should be storing your licenses. CmDongle, the hardware-based protection vessel, offers an impenetrable fortress. CmActLicense, the software-based container, is available with a unique and proprietary technology, SmartBind®. The private and secret keys are stored in an encrypted license file whose key is the fingerprint of the specific PC to which the license file is bound. How to operate encryption is your second important decision; that should depend on the kind of application you have developed and the threat scenario you are going to face in your business model. Finally, there are many cool facts: did you know that in Counter Mode (CTR), encryption with AES is really just about XOR? For example, consider a database field with a Boolean value. A simple encryption with AES returns exactly two possible encrypted values. This means that an attacker would actually be able to derive the unencrypted value for all records by knowing just one record. This is where our presentation begins: we show you practical examples about how to implement CodeMeter in ways that allow it to protect your software today and tomorrow. During this hour together, we discuss: * HASH functions - SHA 256 * Symmetric encryption - AES 128 - Direct encryption in CmContainer - Indirect encryption - Encryption without CmContainer - Selection of the most appropriate operating mode * Asymmetric encryption - ECC 224 - RSA 2048

How To Recover Files from CryptoWall and Preventing it on Network Shares
 
17:36
In this video we explore how to recover from CryptoWall and CryptoLocker, as well as how to prevent it or at least give us a warning. I explain a recent problem at work and some of the best practices, which allow us to contain CryptoWall and get back the file from a prior time period. We explore what needs to be in place to recover from CryptoWall and I show you how Previous Version or Volume Shadow Copy can help. We also examine how to identify malware running with some simple tools like pslist and the wmic process get tools. We also see how to get an email if CryptoWall or CryptoLocker is running on your network by configuring FSRM.

Delete VVV File Extension
 
02:56
http://www.anti-spyware-101.com/how-to-remove-vvv-file-extension VVV File Extension (.vvv) is part of the TeslaCrypt Ransomware that replaces the default extension of an encrypted file with “.vvv”. Our researchers have concluded that this application can get on your computer via infected websites or malicious emails. in the case of email spam, it comes as an attached file that can appear as a photo or a small video. And, once it is on your PC, it will go to work. This particular ransomware was set to encrypt files with the RSA-2048 encryption algorithm. The RSA-2048 algorithm is very strong and decrypting it is no easy task. At present, there is no free decryption tool for this ransomware on offer. VVV File Extension replaced the default extension of documents, images, video and audio files, and other file types. Basically, TeslaCrypt Ransomware encrypts files likely to feature valuable information for which you would be willing to pay the ransom that its developers demand. Furthermore, this ransowamre will prevent you from accessing Windows features such as Registry Editor (regedit), System Configuration (MSConfig), Command Prompt (cmd), and Task Manager. The note present in its interface window says that you have to pay before the timer runs out because the private decryption key will be deleted. Regardless, we suggest removing this ransomware instead with the help of this video.

RuhrSec 2017: "How to Build Hardware Trojans", Prof. Dr. Christof Paar
 
44:45
Countless systems ranging from consumer electronics to military equipment are dependent on integrated circuits (ICs). A surprisingly large number of embedded systems are already security-critical, e.g., medical devices, automotive electronics, SCADA systems or network routers. If the underlying ICs in an applications are maliciously manipulated through hardware Trojans, the security of the entire system can be compromised. In recent years, hardware Trojans have drawn the attention of governments and the scientific community. Even though hardware Trojans have been studied over the last 10 years or so, little is known about how they might look, especially those that are particularly designed to avoid detection. In this talk we introduce several approaches with which a sophisticated attacker could insert Trojan into hardware platforms. We will look at hardware Trojans realized on both, ASICs (application specific integrated circuits) and FPGAs, i.e., programmable hardware.
