Cryptocurrency-Stealing Malware Landscape – Dell SecureWorks

Posted: September 7, 2015 at 11:46 am

Introduction

Bitcoin, a digital currency and payment system introduced in 2009, has been subject to an increasing amount of attention from thieves. Although the system itself is protected by strong cryptography, thieves have stolen millions of dollars of bitcoin[i] from victims by exploiting weaknesses in Bitcoin private key storage systems.

Since Bitcoin's introduction, an increasing number of alternative digital currencies (altcoins) have been created, based on the original Bitcoin client's source code. Even though none of these altcoins have approached the per-coin value of Bitcoin, some have achieved total market caps measuring in the millions of dollars. As a result, these altcoins have also been targeted for theft.

Mass theft of cryptocurrency is usually accomplished through the hacking of exchanges or marketplaces. These thefts are typically well-publicized, and the total number of stolen coins is known. However, another category of Bitcoin theft targets individual users' wallets or exchange accounts via malware such as general-purpose remote access trojans (RATs) or specialized cryptocurrency-stealing malware (CCSM). Due to the skyrocketing value of cryptocurrencies since the beginning of 2013 and the relative simplicity of coding malware and tools to steal cryptocurrency, the Dell SecureWorks Counter Threat Unit(TM) (CTU) research team predicts that CCSM will become one of the fastest-growing categories of malware.

CCSM classification project

To understand the scope of this new threat, CTU researchers embarked on a project to obtain and classify as many CCSM samples as possible. Researchers scanned incoming malware streams with YARA rules, searching for samples that refer to known cryptocurrency software wallet filenames and locations. These samples were classified into families based on similarity. As of this publication, there are more than 100 unique families of malware on the Internet with functionality to steal wallet files or to steal cryptocurrency using other means.

Overall trends

Figure 1 shows the increase in the Windows-compatible CCSM over time. This chart tracks only Windows malware because the Windows portable executable format includes a timestamp in the file headers showing exactly when the malware was compiled. Most malware authors do not bother to alter this timestamp post-release, so it a reasonable and reliable indicator of when a particular sample was created. This chart shows the relationships between average monthly Bitcoin price, new family emergence, and overall total number of families. These variables show a correlation between malware emergence and the price (acceptance) of the currency.

The trend shown in Figure 1 closely follows the overall price trend of Bitcoin. As Bitcoin has become more valuable, more malware authors are targeting it. The record-breaking highs in Bitcoin value from the end of 2013 into 2014 have been accompanied by record-breaking numbers of new CCSM families.

Popularity of coins in CCSM

All CCSM analyzed by CTU researchers targeted Bitcoin. Figure 2 shows the distribution of CCSM-targeted altcoins between January 2009 and the middle of February, 2014.

Figure 3 shows the overall ratio of samples belonging to each malware family. A few malware families seem to be in widespread distribution, while others may have only one or two variants. The "Unclassified" group represents cryptocurrency malware that CTU researchers have not classified as of this publication. The "Miscellaneous" group includes the cryptocurrency malware families the CTU research team has discovered that would not fit into the chart.

CCSM categories

Wallet stealer

The most common type of CCSM is the wallet stealer, a category that includes nearly every family of CTU-analyzed CCSM. This type of malware searches for "wallet.dat" or other well-known wallet software key storage locations, either by checking known file locations or by searching all hard drives for matching filenames. Typically, the file is uploaded to a remote FTP, HTTP, or SMTP server where the thief can extract the keys and steal the coins by signing a transaction, transferring the coins to the thief's Bitcoin/altcoin address.

Most cryptocurrency security guides recommend protecting the wallet with a strong passphrase, preventing the thief from decrypting and using the private keys if the file is stolen. To counter this protection, many of the analyzed wallet-stealer malware families use a keylogger or clipboard monitor to obtain the wallet file's passphrase and send it to the thief.

Credential stealer

Many wallet-stealer families also steal credentials for various web-based wallets, such as Bitcoin exchanges. Some individuals keep a significant amount of bitcoin or other currency in exchanges to trade on price movements. Malware authors are aware of this activity, and many victims have reported that their exchange wallets were emptied without their authorization. In most cases, it is impossible to know exactly what malware was used in the theft, because a full forensic analysis of the victim's hard drive is rarely performed.

Many exchanges have implemented two-factor authentication (2FA) using one-time PINs (OTP) to combat unauthorized account logins. However, advanced malware can easily bypass OTP-based 2FA by intercepting the OTP as it is used and creating a second hidden browser window to log the thief into the account from the victim's computer. Simultaneously, the malware displays a fake "authentication failed" message and blocks the victim's access to the website while the thief empties the account. CTU researchers have not observed a verified example of this type of attack against cryptocurrency exchanges. However, this technique has been successfully used against online banking sites for several years, and it is only a matter of time before CCSM uses this approach.

Man in the middle

CTU researchers have observed at least one family of CCSM that does not exfiltrate wallet files or private keys. Instead, it acts as a "man in the middle," altering the recipient address of a transaction before it is signed. The observed sample runs in the background, monitoring the contents of the clipboard. The malware checks new data in the clipboard for a valid Bitcoin address. If the data is a valid address, the malware replaces it with the thief's Bitcoin address. Victims who do not notice the replacement send the bitcoins to the thief.

RPC automation

Bitcoin and altcoin "reference client" software includes remote procedure call (RPC) functionality, which allows another program to interact with the wallet software. In many cases, a thief with access to this functionality could connect to a running client on a local TCP port and steal the balance of an unencrypted wallet using only two commands (three if the wallet is encrypted and the malware has obtained the passphrase). CTU researchers have not witnessed any CCSM malware taking advantage of this technique as of this publication. It would be difficult to detect this type of theft from a network standpoint, as the transaction would look like any authorized transaction. Another advantage to this technique is that it requires no external command and control (C2) or exfiltration server that can be shut down or blocked.

Detection rates

Across the CCSM samples analyzed by CTU researchers, the average unweighted detection rate across all major antivirus (AV) vendors was 48.9%. Figure 4 lists the major CCSM families classified by the CTU research team and their respective detection rates averaged across all major AV vendors.

Wallet protection

Client software choices

When the private keys for a cryptocurrency are stored on a computer connected to the Internet, the potential for theft exists. For Bitcoin there are alternative wallets, such as Armory and Electrum, which can protect against theft-by-malware by using a split arrangement for key storage. One computer, disconnected from any network, runs a copy of the software and holds the private key that can sign transactions. A second computer connected to the Internet holds only a master public key of which addresses belong to the offline wallet. This computer can generate transactions, but it cannot sign them because it does not have the private key. A user wishing to transfer coins generates an unsigned transaction on the online computer, carries the transaction to the offline computer, signs the transaction, and then carries it to the online computer to broadcast the transaction to the Bitcoin network.

Using a split Armory or Electrum wallet can make processing transactions much safer, although the user must still verify the transaction details to ensure malware on the online computer has not altered the transaction before it is signed. Unfortunately, no such clients currently exist for altcoins, although the need for them is recognized and bounties have been offered for their development.

Hardware wallets

Using two computers in a split arrangement where transactions are carried via "sneakernet" is relatively secure, but the logistics are complicated. A much more convenient method would be to use a dedicated hardware device to store the private keys and verify transactions without the possibility of theft. These devices are already in development, with one (the "Trezor" wallet) due to be shipped within the first quarter of 2014.

Transaction integrity verification

Hardware wallets work well for local transactions but not for safely interacting with a remote website on a potentially infected computer. Securely verifying a transaction that has transited a potentially compromised waypoint requires an offline device that can display the details of the transaction before it is processed. Public-key cryptography signs the transaction data on the bank's server before the data is sent to the user. The offline device can verify the signature of the transaction and determine if any changes occurred in transit. If the transaction shows no tampering, the offline device generates a one-time code that authenticates the transaction. This transaction integrity verification (TIV) should become standard for all financial entities, including institutions and sites that accept cryptocurrencies.

Conclusion

After observing CCSM, CTU researchers drew the following conclusions:

As discussed in Enterprise Best Practices for Cryptocurrency Adoption, wallet security is the most pivotal aspect to keeping funds secure. Implementing the practices outlined in that publication will mitigate most, if not all, of the current threats to cryptocurrency wallets.

Ripple, a Cryptocurrency Company, Wants to Rewire Bank …

Posted: August 13, 2015 at 3:56 am

A digital-currency company thinks it can protect the personal information used to perform identity checks in the financial industry.

Companies built around Bitcoin and other digital currencies mostly focus on storing and transferring money. But at least one company is trying to prove that some of the underlying technology can have a much wider impact on the financial industry.

That startup, Ripple Labs, has already had some success persuading banks to use its Bitcoin-inspired protocol to speed up money transfers made in any currency, especially across borders (see 50 Smartest Companies 2014: Ripple Labs). Now it is building a system that uses some similar cryptographic tricks to improve the way financial companies check the identity of their customers. The system could also provide a more secure way to log in to other online services.

Verifying identity is a constant, expensive headache for financial institutions, which are bound by strict regulations designed to curtail money laundering and support for blacklisted organizations such as terrorist groups. Most banks turn to one of a handful of large data brokers, such as Experian or Acxiom, to power their ID checks. When you open a new account, a bank gathers key personal information and sends it to its broker to verify your identity, and to confirm that you arent on any block list.

Under Ripples system, the same basic process would take place. However, your personal information would be used to generate a unique cryptographic token. A bank could send the token to a data broker that has its own token, made using your personal information at an earlier time. The math underpinning Ripples system would allow the broker to confirm that the data you had given the bank was correct, without either the bank or the broker ever revealing the data itself.

Apples mobile payment technology uses similar technology to protect credit card numbers (see 10 Breakthrough Technologies 2015: Apple Pay). When you use Apple Pay, only a cryptographic token representing your credit card number is transferred to the merchant. That token can be used to charge your card, but it wont reveal anything to anyone who manages to steal it, and it cannot be reused.

Stefan Thomas, chief technology officer of Ripple, says its ID verification system should reduce the risk that personal data will be stolen or accidentally leaked and should also be faster than the systems used today, which have developed gradually over decades and still use outdated technology. He says Ripple decided to develop the technology after it became clear that the financial system needed more than just new ways to transfer money.

Thomas adds that by cutting costs and security risks, Ripples system might allow cheaper data brokers to emerge. It could also make it easier for banks to operate in poorer parts of the world, where verification systems can be particularly expensive to operate, even for U.S. banks, he says. And Ripples engineers are also working on ways their protocol can be used to log in to online services.

Sarah Jane Hughes, a law professor at Indiana University who specializes in payment systems, says Ripple has identified a legitimate opportunity. Companies spend a lot on complying with identity verification rules, and mistakes are expensive, she says. For example, PayPal agreed to pay $7.7 million to the U.S. Treasury last week for failing to block just under 500 transactions involving people subject to U.S. sanctions. If you could do verification more rapidly and with a greater degree of certainty, it would be hugely valuable, says Hughes.

However, Hughes says, switching to a new system would not be easy for most financial institutions. They would probably have to retain the old system for some time for compatibility reasons. That means Ripples idea would have to deliver significant benefits to gain traction.

Nvidia Is About To Steal The Cryptocurrency Mining Crown …

Posted: August 8, 2015 at 7:20 pm

Buried on the 17th page of Toms Hardwares GeForce GTX 750 Ti graphics card review is a simple benchmark result that will dramatically disrupt the landscape of cryptocurrency mining. In fact, its the kind of data that should send AMD back to the drawing board at least if they want to maintain their choke-hold on the mining hardware market.

Historically AMD has been the undisputed crowd favorite of miners looking to stock up on new forms of digital currency like Dogecoin and Litecoin. AMDs Radeon graphics cards possess a secret sauce that allows significantly more powerful compute capabilities, at least the kind required for Scrypt-based mining.

That is, untilNvidiareleased their new Maxwell architecture this week.

PNYs GTX 750 ti | Image Credit: PNY Technologies

As we learned from my introduction to the GTX 750 Ti,first-generation Maxwell cards exhibit a 35% peak performance boost per core and twice the performance per watt. They also blow Kepler hashrates out of the water. Based on what Im seeing with the 750 Ti, Nvidia is poised to embarrass AMD in the performance-per-watt race and thats a substantial factor when youre paying the inflated energy bills caused by mining.

Nvidia didnt breathe a word of Maxwells seriously improved hashing ability in their marketing copy or press briefings, but Toms Hardware discovered it, and Ive been able to replicate their findings with multiple 750 Ti cards from both Nvidia and PNY.

Hashrate using a reference 750 Ti 1GB card from Nvidia (Software: Cudaminer)

What youre looking at in the image above is a hashrate of about 242kh/s using Nvidias reference 750 Ti 1GB graphics card ($139). This is significant for several reasons. First, the 750 Ti is a 60Watt card and doesnt even require a PCI-E power connector. You could plug this card into a cheap box from HP or Dell with a 300W power supply and have power to spare. Second, the temperature never seems to breach 65 degrees Celsius, and it runs considerably quieter and cooler than the AMD 260x ($119), which achieves a peak hashrate of 206kh/s and consumes nearly 130Watts of power.

Hold on a minute! I can hear you saying. AMDs 260x is $20 cheaper than Nvidias entry-level 750 Ti! Thats true, but the nominal price difference quickly evaporates when you consider how the 750 Ti sips power, which matters in the long run. Additionally, Toms Hardware ran the same mining environment test with AMDs upcoming Radeon 265 ($149) and achieved a peak hashrate of 252kh/s and remember that the Radeon 265 is a 150Watt card.

For that same price of $149, heres what I pulled off with PNYs 750 Ti 2GB with a moderate (and stable) overclock:

Americas #1 Cryptocurrency: The Secret Currency …

Posted: at 8:08 pm

A sudden avalanche of folks have been asking about this pitch again, so I thought Id re-share and update my thoughts on something I wrote in the Friday File for the Irregulars back in October of 2013 so yes, this is getting a little old. Much of this is from that original note, or from my update back in January of 2014, though Ive gone through and updated my thoughts (and some of the numbers) a little bit.

From my quick glance, the core of the spiel from the Stansberry folks hasnt changed much for this Secret Currency since then, other than to call it the #1 Cryptocurrency now that that term has entered the popular lexicon (and indeed, the ad is not dramatically different than it was when I first covered similar ads of theirs five or six years ago).

The one thing thats particularly different in the last year or two is that they use the curiosity about Bitcoin to catch your attention

The ad back in 2013 started out as a warning about Bitcoin:

Urgent Message for U.S. Investors:

Do NOT buy Bitcoin until you watch this public message

This is the true story of alternative currencies in America the one you wont hear anywhere else. The story only wealthy families know. Please take five minutes to watch this message and avoid making a very costly Bitcoin mistake.

And then went on to compare Bitcoin to a host of past internet failures or value-destroyers like Webvan and Pets.com and Groupon, and then makes the argument that the secret currency does the same things Bitcoin does (provide some privacy, get away from the US dollar, etc.).

Which is sort of true I have some experience with both this secret currency and with Bitcoin, I tinkered with Bitcoin myself for a to see how it worked and whether it might be a viable alternative to using credit cards, and Im not all that impressed with how useful it might become at the moment though I still have maybe half a bit coin sitting in a wallet somewhere.

This is how they introduce the ad now:

Harry Potter And The Cryptocurrency of Stars | Kalzumeus …

Posted: at 8:08 pm

If youre wondering why my blog suddenly has Harry Potter fanfic click this to show the spoiler otherwise it might be more fun to dive right in.

So I thought it was worth understanding how Stellar works, at the protocol level. It turned out to be easier to explain with a story than a code sample.

With apologies to J.K. Rowling, here we go:

Goblin Banker: So, young Master Potter,I understand that these last few days have been a bit trying for you, but on the upside, youre filthy stinking rich.

Harry Potter: Im still having trouble wrapping my head around piles and piles of gold coins in a vault guarded by a dragon. What did you call them again?

Goblin Banker: Galleons.

Harry Potter: And werent there Sickles and Knuts, too?

Goblin Banker: Meaningless complications for the moment, sir. Lets just focus on your galleons.

Harry Potter: What is a galleon worth, anyway?

Goblin Banker: What is anything worth, young Master Potter? An apple or a dragons egg or the limb of an ancient yew severed in a lightning strike? All things are worth what someone will happily trade you for them.

Navigating the cryptocurrency minefield

Posted: April 14, 2015 at 9:47 pm

Contrary to popular belief, virtual currency is actually extremely secure

The online payments industry is in a phase of change with developments coming thick and fast in how payments are made, on what devices and in what form.

Understandably, many businesses trying to navigate the online payments industry are finding it hard to know which direction to take in these turbulent times.

However, the variety of new payment opportunities also makes it an exciting time for those who are willing to take a gamble and ride the rapids, so to speak.

One of the most intriguing developments in the payments industry is the rise of cryptocurrencies, which have the potential to completely alter the landscape of the industry as we know it.

>See also:Something you didn't notice in the Chancellor's Budget 2015: a step forward for bitcoin

Free from any banking or state authority, and designed for the world of online payments, cryptocurrencies are arguably the next step in the evolution of money. Yet, despite all its revolutionary potential, this is a payment option that many businesses are wary of.

The big concern with cryptocurrency is how secure an investment it is without the same levels of regulations in place, and with no insurance, how can you guarantee your money will retain its value, or be there at all?

Moreover, only years into the short history of cryptocurrency there are already real-life examples of how it can go terribly wrong.
