Wall Street is Backing Out of CryptoWall Street is quietly moving out of the crypto market, Bloomberg reports. While the market has continued to be battered by news of fraud and imminent regulatory crackdowns, there was a time when it seemed like Wall Street had started to warm up to the rise of crypto assets.Last year, when the crypto industry enjoyed what was probably the biggest bull run in its history, it seemed a lot of mainstream financial companies were also ready to join the bandwagon. Names like Goldman Sachs, Fidelity Investments and Barclays Bank Plc. were all affiliated with reports to open cryptocurrency divisions, and these speculations sent ripples around the financial industry.Goldman Sachs’ Trading Desk DreamsGoldman Sachs was one of the first Wall Street firms to show interest in Bitcoin futures, and rumors claimed that the firm was working on developing a seperate crypto trading desk. The investment bank partnered with Galaxy Digital and led a $57 million series B in..... Continue reading at: https://news.yahoo.com/wall-street-backing-crypto-204020484.html
Long story short a client has been hit with CryptoWall and it's cheaper to pay the ransom than it is to try and recreate the work that's encrypted. We're in Canada, and having a hell of a time trying to get Bitcoins NOW as time is running out on the ransom. We've signed up for sites like Circle in an attempt to get bitcoins but most seem to be US only. How the heck can we get some bitcoins immediately?
Today at work I encountered a computer with a variant of the "Cryptowall" virus. Basically, it takes the common files on your computer (jpegs, .doc, pdf and similar), encrypts them and then holds them hostage until you pay the ransom. The instructions mentioned the TOR browser and online it's often said they want the payment in bitcoin. I'm not a proper IT technician so I couldn't do much for the poor guy who just lost many valuable files but the more I read about it, I felt it was an equal part scary and brilliant. It also struck me as very cyberpunk, hence why I'm posting it here. The very idea of locking down somebody else's files, with only you having the key, and then proceeding to make them pay a big sum of money to get their stuff back just felt so incredibly high tech, low life to me.
Are there any sites/databases with a list of known bitcoin addresses linked to ransomware?
Hi all, I'm asking this due to part of an university assignment where I have a full data set of bitcoin transactions from 2010 - 2014 and was wondering if anyone knew of any sites that contain known bitcoin wallet addresses used by ransomware? I have a few of the well known ones such as Cryptowall but I'm trying to find as many as possible. Any help would be much appreciated!
I show up to one of my client's offices today, and I'm greeted by a torrent of "Mother fuckers, cocksuckers, stupid pricks etc..". So right away I'm thinking what a fun day this is going to be. After getting settled in and the owner calmed down a bit, I was able to find out what was going on. Turns out, he had a cryptowall placed on his computer, demanding something called "Bitcoin." I could hardly contain myself... I proceeded to sympathize with him. I told him about how it was the favored currency of kiddie fuckers, degenerate gamblers, terrorist, and "investors" world wide. Needless to say he was skeptical of such great fundamentals, but after doing his research he came around. I informed him that since bitcoin had lost 70% of its "value" the neckbeards needed another way to scam money from people and so they invented a computer virus. Turns out his IT deptartment had backups and just did a fresh install, wasted tons of time, but at least he didn't have to pay. 10/10 this business owner will suck federal reserve cock until the day he dies. So everyone make sure you support this business.
Introducing eDollar, the ultimate stablecoin built on Ethereum
As someone who's been obsessed with pegged cryptocurrencies for the past 6 months, I was delighted to find out that even with just my meager programming skills, developing for Ethereum is so incredibly easy that I've been able to come up with what I believe is close to being the perfect design for a stable cryptocurrency. In short, the eDollar is a token pegged to the USD that is issued in a manner similar to bitUSD, and that has a DAO (called Maker) backing it and providing liquidity similar to the system of liquidity providing custodians that NuBits uses. The purpose of eDollar is to give average people a currency they can use on the ethereum network to interact with dapps, without having to worry about insane volatility like with bitcoin and other 1st gen cryptocurrencies. It also gives ethereum investors the possibility to take leveraged ETH positions (albeit with very high collateral requirements). To see a full (but rough) description of the features of the eDollar design, you can check out this post on the Maker forum: http://makerdao.com/index.php?topic=4.0 (the forum design is really fancy, I know :p) To see the eDollar contract with comments, check: http://makerdao.com/peggedCoinRemake.sol To see the test frontend http://makerdao.com/edollarfrontendtest.html# (edit I should add that the front end is not currently set up to work with the latest version of the contract, so the dapp can't actually be tested atm without adding new ABI calls) These are the basic pointers of the design:
If EUSD is currently trading above 99 cents, then anyone can issue new EUSD by putting up 3 USD worth of ether as collateral for every 1 EUSD (300% collateral requirement).
After issuing EUSD, the issuer gets a debt that has to be covered by burning an equal amount of EUSD if they want to get their collateral back.
If the collateral/debt ratio for a position ever goes below 150% anyone can perform a "hard margin call", getting the entire collateral balance in return for covering the debt.
In practice this should never happen due to the existence of Maker (trading as MKR), the "guardian DAO". Maker has the ability to perform soft margin calls and forced covers.
a soft margin call can be done on any position with a c/d ratio below 200%, and with penalty of up to 5%. The issuer will get the remaining collateral after the value of the debt and the penalty (if any) has been subtracted from it.
a forced cover enables Maker to cover any position at the market rate as determined by the feed. This ability ensures that Maker can guarantee liquidity for users who wants to get out of eDollar.
Maker will earn income by staking with the eDollar collateral. Only a small portion of the collateral will be used for this since it gets locked up for 3 months at a time. A system will be in place to ensure that the collateral cannot be stolen by Maker, and that it only gains access to the profits from the staking.
The profits will be used to buy diversified collateral, such as gold vouchers from DGX.io. This diversified collateral will be used as a last resort in case the ether price crashes so fast that some positions become undercollateralized before they can be margin called (known as a black swan event).
The money will also be used to pay for price feeds from Augur, and to fund infrastructure such as the EtherEx foundation and the Ethereum Foundation, as well as be distributed to MKR holders as dividends.
Maker can upgrade its own guardian contract, and update vital parameters of the eDollar contract (such as changing the source of price feeds, or changing collateral requirements). To prevent abuse these actions have to be primed with a delay (which can be several months for extremely vital functions), so that users will be able to notice and withdraw their funds from the contract if this power is being misused.
To give users some amount of privacy, a simple coinjoin system will be avaiable soon after launch, called Shuffle. This should provide privacy equal to that of Darkcoin, but the eventual goal will be to have a zerocoin level privacy implementation that makes all eDollar transactions 100% anonymous by default.
Shapeshift will be natively integrated in the UI to allow users to seamlessly send and receive eDollar as bitcoin.
A bunch of features to make life easier for the user will be implemented in the eDollar front end, some based on bitcoin/shapeshift (shopping, debit cards) and some being curated lists of ethereum dapps that accept eDollar (gambling dapps and possibly augur and other prediction markets).
eDollar will trade against bitcoin and ether on etherex, and will also trade on a single centralized exchange where high liquidity will be ensured by Maker and the centralized market making company Cryptowall.
other assets can be created by anyone using the same system, but be collateralized by eDollar instead in order to reduce risk (since it's easier to determine the right collateral requirements when the collateral isn't volatile). This opens up the possibility to trade any asset on the ethereum block chain. Maker will initially create and keep liquid AAPL, gold and CNY on EtherEx as a proof of concept that anything can be done as long as there's a price feed.
I made this post and the intentionally hyperbole claims in the hopes that I'll provoke the armchair economists out of the woodwork to start a discussion on how risky this type of pegged asset it, and what other mechanisms can be put in place to minimize the risk. The great effort of convincing dapps to use eDollar has also yet to begin, and there needs to be a community wide discussion on how to handle metacoin deposits to dapps before they can even implement it. In the long run I'm hoping to have an ongoing discussion about every aspect of eDollar, pegged currencies and other ethereum based assets on makerdao.com, so anyone will have easy access to the different arguments and points of view.
Older report from Dell but I just came across it while trying to build a list of strong use-cases for butts: http://www.secureworks.com/cyber-threat-intelligence/threats/cryptowall-ransomware/ "Based on post-mortem data collected by researchers, CryptoWall has been less effective at producing income than CryptoLocker. Both malware families accepted payments via Bitcoin, with 0.27% of CryptoWall victims and 0.21% of CryptoLocker victims paying ransoms in bitcoins. CryptoLocker also accepted MoneyPak, and an additional 1.1% of victims paid ransoms using pre-paid MoneyPak cards. As of this publication, CryptoWall has only collected 37% of the total ransoms collected by CryptoLocker despite infecting nearly 100,000 more victims. CryptoWall's higher average ransom amounts and the technical barriers typical consumers encounter when attempting to obtain bitcoins has likely contributed to this malware family's more modest success. Additionally, it is likely the CryptoWall operators do not have a sophisticated "cash out" and laundering operation like the Gameover Zeus crew and cannot process pre-paid cards in such high volumes." TL;DR fiat beats butts even in the realm of ransomware. So I'm back to just claiming it's only marginally useful for drugs.
A customer of mine is going to pay the ransome of $500 to get their files back. My question is I know ZERO about Bitcoin and am having trouble getting started and how to purchase the currency. We cannot seem to buy $500 with a credit card and there is no way we are going to do a wire transfer. We found Expresscoin in Santa Monica and I am waiting on a return phone call to go down there with $500 in cash to buy the Bitcoins. How does this work, do I bring a USB hard drive to put the Bitcoins on or do I sign up for an online account? Please no comments about backup or shadow copies or all of that. This post is just about CryptoWall and Bitcoin payment.
There's this computer here that was locked by CryptoWall - a piece of malware which encrypts files with a certain extension (mostly important documents, photo's etc) with a 2048-bit RSA key while they securely store the private key on their servers. The programmers are using bitcoins to take ransom for the files and that's the reason I've started this question. Would it be possible to create a fake transaction to trick the CryptoWall system to think they have paid, even though the transaction hasn't been verified? I could imagine them not really taking the time to actually accurately check if a transaction has had its verifications. Though, I'm not sure obviously as I'm not an experienced cryptocurrency user. Thoughts? Input? :)
Got hit with cryptowall at work, need help buying bitcoins with credit card ASAP
Hello all, this morning I found out we were hit with cryptowall at work. The fee is 1.27 bitcoins. I have never bought them before and all my boss gave me was a credit card. I already created a wallet but I can't really find any place to buy ~$500 with a credit card. Does anyone have any suggestions at all? This is urgent. Thank you so much.
[LPT request] Saw a friend get hit by ransomware, and it freaked me out. What can I do to prevent it?
He got some cryptowall ransomware that basically encrypted all his .doc, .pdf and other files and the only way out was to send the attacker 0.5 bitcoins. There was nothing he could do to decrypt it, though I figured that we could revert to olderr versions of the files using an application. What are the best practices to avoid something like that? I don't click on any surveys/awards/etc. I run Malwarebytes every week and have Windows Security Essentials running all the time. What else can I do? I don't have system restore set up.
One of my company's customers got struck with Cryptowall 2.0 and it made its way into the offsite backup so all their files are encrypted. Thus eliminating the option of wipe-and-reload. Are there any reputable tools out yet to decrypt the files? I have also heard rumors that sending in the Bitcoin no longer guarantees a valid decryption key. How screwed are we?
Sheriff's Office Forced To Pay Ransom For Their Own Case Files
Story is here: http://www.jrn.com/newschannel5/news/Sheriffs-Office-Forced-To-Pay-Ransom-For-Their-Own-Case-Files-282493831.html What really has me wonder is that per Det. Jeff McCliss: Cryptowall doesn't access or tamper with files, but keeps them locked until the user pays a ransom. In this case, it was in the currency bitcoins worth $500. I could be wrong, but isn't encryption technically changing the file and since this change occurs, could it not be argued that evidence is tampered with? Even with hashes physically recorded, I can see this being a dicey issue. Thoughts?
Getting my Armory offline wallet balance transfered
A long time ago, when bitcoin values started to go up- I setup an Armory offline wallet. Very cool, and secure system. Too secure. I don't use it much, and Armory has this nasty habit of needing the full transaction history of bitcoin before it will work. I've tried a few times today, and it keeps giving up. I've got the offline PC here to, along with a paper "backup" wallet I created when I first installed everything. I just want to move it all to Electrum. It's been on my list of things to do for a while, but as I've said in another thread, I'm trying to help a friend help a client pay a cryptowall ransom- and don't want to wait hours and hours for Armory to sync up. I messed around a little with Electrum and blockchain.info- trying to find some way to import off the Armory paper wallet- but I'm not having any luck. Any ideas?
Digital Artist: Back Up Your Artworks on an unattached external storage now.
This September seems to be the peak epidemic period of Cryptowall Ransomware and all of its numerous variants. CryptoWall is a file-encrypting ransomware program that was released around the end of April 2014 that targets all versions of Windows. When you are first infected with CryptoWall it will scan your computer for data files and "encrypt" them using RSA-2048 encryption so they are no longer able to be opened. There is no known utility to decrypt RSA-2048 encryption without the private key held as ransom by the evil virus writer. Brute force decryption approach would take around 100 years to decrypt a file. Once the infection has encrypted the files on your computer drives it will open a Notepad window that contains instructions on how to access the CryptoWall Decryption Service where you can pay a ransom to purchase a decryption program. The ransom cost starts at $500 USD and after 5 days goes up to $750 with the cost increasing again after another 24 hours to a maximum ransom of $1,500 USD. This ransom must be paid in Bitcoins and sent to a Bitcoin address that changes per infected user. Besides your local hard drives, it attacked all mapped network drives and all external storage devices attached to your computer (flash drive, USB external hard drive, thumd drives, USB sticks... everything You name it). This virus also encrypted files on your Cloud backup such as Dropbox drive or Google drive too. It slips by Anti-virus and anti-trojan software on your pc without any detection (The new CryptoWall samples were not detected by any of the 55 antivirus products used on the VirusTotal website when they were discovered Sunday), so more often than not when You found out about the virus, all your files on all your drives have already been encrypted. Some digital artists have lost all their artworks by not having a reliable unattached incremental back ups or having an unreliable external backup drive which was attached to the pc at the time so the back up was also encrypted. All your personal documents and artworks could be wiped out in around 2 hours. On the average it takes only around 2 hours to encrypt a 2 terabyte drive. Please digital artists, back up all your artworks on a reliable external hard drive and disconnect it from your computer after a successful back up and store it in a safe place. Info about this scary virus Regards, :) DL ( I have just lost all my drawings without backup) :)
I apologize if we are skipping some rules for the sub but we are at work and we have had the cryptowall virus. We are going to pay the ransom - yes we know the risks, sadly it's where we are with this thing. None of us have used bitcoin and we have set up probably 10 accounts by now but have yet to be able to simply purchase any using a card. Either the verifcation takes days or simply cards are not an option. If someone (with a good rep) would like to sell us some we will gladly pay including some fee that an exchange would have charged. Thanks! If someone can decrypt these files we would simply just pay you.
He called me and asked me to come ASAP because he said he couldn't access any of his file son dropbox. I went, thinking he had done something stupid. But when I opened his dropbox folder, every subfolder had three files titled "DECRYPT" When I opened the text file, it said that all his files had been encrypted by an RSA-(forgot the number) level encryption and that there was nothing for him to do except send 0.5 bitcoins within a week. If he didn't comply, he would have to send 1 BTC after that. I think the ransomware was called cryptowall and after a couple of hours of searching online, it was evident that if one didn't make backups (he hadn't) it was difficult to get the files back. It's possible to go back to an older version, but we didn't have much luck. But at the end, he went "Fuck this bitcoin nonsense. I hope they ban it." I know this isn't a big deal in the grand scheme of things, but it's a deal to take note of.
Hi Guys, A break / fix client contacted me yesterday regarding a CryptoWall incident. I got setup on coinbase account but, it says its going to take 5 business days to transfer. Does anybody have 1.87 bitcoins that would be willing to part with? I will transfer the coins back once the funds become available. I can even do paypal if that works. Msg me. Thank You, eaglefan9000
Cryptowall 3.0. Just like Cryptowall and Cryptowall 2.0, this threat is used for collecting ransoms. This version spreads with the help of exploit kits, what means that it can get into the system easier than its previous examples. Once it infiltrates the computer, it encrypts needed files with the help of the same RSA-2048 algorithm and starts asking the money. cryptowall‑3‑bitcoin. 13 Oct 2015 - 02:13PM.
