Photo by Although exchanges, wallets, and other cryptocurrency custody services are strengthening their defenses, hackers continue to innovate and outpace even the current state of the art in cybersecurity, the CipherTrace report notes. For example, many breaches involve blended attacks in which hackers employ multiple techniques— including SIM swapping, phishing, URL hijacking, etc. As a result, both end-users and the exchange IT staff are unaware of these highly unusual transfers until the thieves have made off with their loot. To put it simply, an exit scam is when scammers launch a new cryptocurrency based on a promising concept.

When Reporting on Defcon, Avoid Stereotypes and A.T.M.s


On this week's show we're chatting with The Grugq about secure messaging. Facebook has announced it's rolling out an end-to-end encryption feature and the reaction to this wonderful announcement has been somewhat bizarre.

We'll be talking to Grugq about why crypto absolutists are hating on companies that are rolling out non-default e2e features. We'll also talk about a couple of interesting case studies in which e2e encryption did absolutely nothing for the people using it. This week's show is brought to you by Sensepost, an absolutely fantastic security firm that operates in England and South Africa. Sensepost has been an academy for security luminaries over the years.

Haroon Meer of Thinkst was an early stage employee, Maltego creator Roelof Temmingh was a co-founder. So, they're smart. They've been doing this for 15 years and Sensepost's Daniel Cuthbert will be joining us in this week's sponsor interview to talk about what courses they're offering and who winds up actually taking them.

The really interesting part is it's not always security professionals in those courses. Oh, and do add Patrick and Adam on Twitter if that's your thing. Putin signs new anti-terror law in Russia. Edward Snowden is upset.

Texas Imperial Software DefCon 18 challenge

It can only be termed a tragedy if you own thousands of Bitcoin yet cannot access it because you saved them in a password-protected ZIP file, and later forgot the password. Michael Stay was a crypto-analyst and reverse engineer in the s and worked for Google for around six years. The Russian investor contacted Stay via LinkedIn in October , in which he asked him to help in retrieving the password. The investor was more than willing to pay the amount because the crypto he owned was worth thirty times more than what he had originally paid in To unlock the ZIP file, Stay had to develop a program to hack into the file by trying several different combinations.

(Rosic, ). Overall confidence in the prudential integrity of Bitcoin and other cryptocurrencies has also declined, in the.

A personal perspective from recent experiences as a first time DEF CON attendee has left a desire to return next year. I was not sure what to expect, where to go, or what to see. The content of the workshop was detailed and kept my interest, there was an issue with having no power strips or outlets for anyone attending to charge their machines. Halfway through the course most people lost power to their machines and could no longer participate. Most of my time was spent exploring what the conference had to offer and participating in the OpenCTF challenge.

It wasn't a total surprise that The Guy, as Stay calls him, had found the former Google security engineer. Nineteen years ago, Stay published a paper detailing a technique for breaking into encrypted zip files.

The blockchain is the underlying technology that enables the bitcoin cryptocurrency to exist. A foundational component of this technology is its complex cryptosystem. When you create a bitcoin wallet, under the hood you are creating an Elliptic Curve key pair based on Secpk1 curves. The key pair has a private key and a public key.

Course Description Learn essential concepts of cryptography as it is used on the modern Internet, including hashing, symmetric encryption, and asymmetric encryption. Then perform hands-on projects calculating hashes and encrypting secrets with RSA, and compete to solve challenges including cracking Windows and Linux password hashes, short and poorly-chosen RSA keys. No previous programming experience required. The best computer to bring is a bit Linux machine, real or virtual. However, the Python projects can also be done on a Mac. I will have a few loaner computers available. As you can see below, the course will include hands-on projects with blockchains, using Multichain, Ethereum, and Bitcoin.

The purpose of this infographic is to visualize the size of large cryptocurrency hacks that have occurred in the past as if they all happened today. The hacks included in this infographic extend beyond exchanges, as there were other large entities that experienced cryptocurrency hacks, such as marketplaces like Silk Road 2. All hacks in this infographic are displayed as if the price of bitcoin were the same when they occurred, in order to visualize their magnitudes in relation to one another.
