Cisco Discovers “PoSeidon” POS Malware

Published

on

Researchers at Cisco’s Talos Security Intelligence and Research Group have discovered a dangerous, new form of point-of-sale (POS) malware dubbed “PoSeidon”. The malware builds upon previous trojans like ZeuS and BlackPOS that affected retail stores like Target and Home Depot. Many credit card terminals run legacy versions of Windows, which leaves them vulnerable to all sorts of malware. And with new threats like PoSeidon, even newer terminals are at risk.

PoSeidon – A Nightmare for Both Customers and Merchants

Cisco Discovers "PoSeidon" POS MalwarePoSeidon is an alarmingly sophisticated piece of software that relies on outdated and insecure technologies like credit card magnetic stripes. Information stored on a magnetic stripe can easily be encoded onto a new magnetic stripe on a fake credit card. Underground stolen credit card markets thrive in the U.S. due to America’s reliance on magnetic stripe cards. Chip-based “EMV” cards are much harder to clone and are common in many countries outside North America.

The PoSeidon Malware starts by injecting a “Loader” that maintains persistence on the POS terminal. This allows PoSeidon to stay on the system even if the terminal is rebooted. Next, the malware contacts an external server to download a keylogger called “FindStr”. FindStr scrapes the terminal’s memory for number sequences that could be credit card numbers. The software then checks to see if the numbers are, in fact, credit card data by using the Luhn algorithm. Anything else is filtered out before the data is sent to external servers of Russian origin. From that point, stolen credit card data is likely sold in various black markets.

“PoSeidon is another in the growing number of Point-of-Sale malware targeting PoS systems that demonstrate the sophisticated  techniques and approaches of malware authors,” says Cisco. The company encourages network administrators to consider best security practices to prevent large-scale infections due to malware like PoSeidon.

“As long as PoS attacks continue to provide returns, attackers will continue to invest in innovation and development of new malware families.”

    It is essential ( and inevietable) that we rapidly move away from a “pull system” of transaction operation (credit/debit cards which need customers to reveal their security codes ) and which have numerous hackable storage databases with various intermediaries to “verify” money transfer.

    The only medium/longterm solution for Banks/Merchants is to utilise a decentralised blockchain “push system” application for securing/processing payments, where no security codes are sent along with transfer data, but the transaction simply “pushes” the value required and doesnt allow any hacker the ability to pull money from any intercept of the data.

    This system already exists, and is being developed at a phenomenal rate. Its called bitcoin and runs on the decentralised blockchain protocol.

    If you are still not up to speed with where bitcoin is going,( maybe still listening to the shills and misinformed media) you need to read up fast. Those looking ahead can clearly see that peer-to-peer “push” transaction technology is going to have a massive impact on the likes of MasterCard and Visa in the remaining years of this decade.

    Its going to be fun – trust the Rat !

Crypto-Security Testnet Surpasses Key Milestones

Published

on

Security and has been combined with micro-compucomputing are a combination which ascended to greatly relevant, both economically and financially, since the early days of commercial internet technology, the John McAfee associated era of anti-virus software, and fears of ‘millennium-bug’ (‘Y2K’)-induced societal meltdowns.

As a market player, ‘cybersecurity‘ is hailed for its continuedvalue and growth, with recent implementations advancing in tandem with technological development. With ‘blockchain’ having become a key buzzword in recent years, it comes as little surprise that digital security providers have been attempting to identify and provide protection against cryptocurrency related scams.

Examples of these include ‘malware‘ AKA ‘malicious software’. They are often created with the aim of illicitly subvert the processing power of the victim’s device for use towards the mining of cryptocurrencies, or lock and potentially delete highly sensitive data (such as Ransomware’).

Cybersecurity and Blockchain

Crypto attacks can affect almost any person or institution: from private wallets and exchanges, to cryptocurrency operators, and even sometimes unsuspecting users of internet browsers with no relation to blockchain based services.

In an article published at CCN in August 2018, I wrote about the large prolificity and news coverage of cyber-attacks carried out against cryptocurrency organisations: with a majority of them involving the theft of high-value quantities of tokens or sensitive data.

Key points raised in the piece include the identification of wallets and exchanges as high-value targets for potential thieves, as well as a discussion surrounding a study of over 1000 participants in which none of the top exchanges were “lauded for security”.

As cybersecurity has been exposed as a fatal flaw in the unauthorised access / theft access of finances and data, it has also drawn a spotlight on the various methods employed by the companies which suffer these attacks.

Middleware, Wear and Tear

Some teams attempt to protect their data and finances through the creation and implementation of their own proprietary cybersecurity solutions whilst others seek the tender of others,

‘Middleware’ is nothing new and has long been utilised as a means of implementing third-party solutions as a means of shifting professional a legislative liability regarding essential functions of a brand technology.

It’s a creation by third party product / service providers that sits between external and internal code in order to facilitate functions or protections.

Decentralized Security Testnet

REMME is a project harnessing blockchain technology to create a distributed cybersecurity solution for enterprises.

Its now-released testnet has already demonstrated the efficacy of storing hashed Public Key Infrastructure certificates on the blockchain, and with 300 pilot program participants signed up, REMME isn’t short of applicants eager to trial its distributed identity and access management solution.

‘Distributed Identity and Access management’ (IAMd) and ‘Public Key Infrastructure’ requests (PKId) count amongst two of the primary features of the proprietary REMChain testchain network infrastructure. Both claims of which have come from CEO Alex Momot, who additionally praised “The interoperability of the public blockchain and sidechains”.

Additional features include the ‘REMchain block explorer’ – ‘node monitoring’ (connected to five nodes worldwide) – REMME WebAuth demo application.

While a pilot program reportedly attracting over 300 global enterprise applicants, REMME feels confident about the future of their long terms plans: which include full integration existing enterprise systems (ERP, CRM, Accounting software etc.).

MyEtherWallet Compromised in Security Breach; Users Urged to Move Tokens

Published

on

Popular cryptocurrency service MyEtherWallet (MEW) is urging users to move their tokens after the platform succumbed to its second cyber attack of the year. As the company reported earlier, hackers targeted MEW’s popular VPN service in an attempt to steal cryptocurrency.

Hola VPN Users Compromised

Rather than target MEW directly, hackers took control of the Hola VPN service, which claims nearly 50 million users. For the next five hours, MEW users who had the Hola chrome extension installed and running on their computer were exposed.

MEW took to Twitter to urge users to move their funds immediately.

“Urgent! If you have Hola chrome extension installed and used MEW within the last 24 hrs, please transfer your funds immediately to a brand new account!” the company said. It added the following message shortly thereafter:”We received a report that suggest Hola chrome extension was hacked for approximately 5 hrs and the attack was logging your activity on MEW.”

At the time of writing, MEW’s Twitter feed had no further updates.

MyEtherWallet is used to access cryptocurrency wallets, where users can send and receive tokens from other people.

The company reportedly told TechCrunch that the attack originated from a Russian-based IP address.

“The safety and security of MEW users is our priority. We’d like to remind our users that we do not hold their personal data, including passwords so they can be assured that the hackers would not get their hands on that information if they have not interacted with the Hola chrome extension in the past day,” MEW said, as quoted by TechCrunch.

It’s not yet clear how many users were compromised in the attack or how much, if any, was stolen from their wallets. MEW suffered a similar incident in February after a DNS attack wiped out $365,000 worth of cryptocurrency from users’ accounts.

Cyber Attacks on the Rise

The attack on MEW came less than 24 hours after Hacked reported another major cyber breach involving Bancor, a decentralized cryptocurrency exchange. The security breach compromised roughly $23.5 million worth of digital currency, including Ethereum, NPXS and BNT, Bancor’s native token.

Last month, a pair of South Korean exchanges fell prey to cyber criminals, prompting local regulators to expedite their approval of new cryptocurrency laws.

It has been estimated that a total of $761 million has been stolen from cryptocurrency exchanges in the first half of the year, up from $266 million in all of 2017. That figure is expected to rise to $1.5 billion this year.

CipherTrace, the company behind the estimates, told Reuters last week that stolen cryptocurrencies are mainly used to launder money and aid criminals in concealing their identities.

Mt. Gox vs. Bithumb: That Was Then, This Is Now

Published

on

Bithumb now shares something in common with the Tokyo-based shuttered bitcoin exchange Mt. Gox — both suffered a hack on about the same date, June 19. It’s a club that no exchange wants to belong to and that Bithumb happened on the seven-year anniversary of Mt. Gox’s maiden attack has to be more than an eerie coincidence.

It’s a stark reminder of the risks involved with keeping funds on an unregulated exchange, vulnerabilities that cost South Korea’s Bithumb some $36.6 million in digital cash and Mt. Gox $450 million in hacked bitcoin and its future. The Mt. Gox theft unfolded over a series of hacks that culminated in 2014. Though it’s still early on in the Bithumb hack, it appears the South Korean exchange will recover from the security breach. So what do we know now that we didn’t on June 19, 2011?

Then vs. Now

Former Coinbase official Nick Tomaino, who is also the founder of crypto fund 1 confirmation, reflected on the Mt. Gox hack in what proved to be a prescient tweet given the Bithumb attack that was about to surface.

The thing to note about Mt. Gox is that the Japan-based exchange in 2011 controlled most of the BTC trading volume, approximately three-quarters of it by average estimates — more if you ask Tomaino. Since bitcoin fever caught on in 2017, there are more than 500 cryptocurrency exchanges on which trading volume is shared. Binance boasts the highest trading volume and captures nearly 15% of bitcoin trading. It’s much less than Mt. Gox days but still a little high.

The other thing to note is that the Mt. Gox hack or actually hacks, as there were multiple attacks on the exchange over several years, was a mysterious event that was shrouded in controversy and mistrust of a key executive. Bithumb, on the other hand, confronted the hack seemingly right away on Twitter and has not let any grass grow under its feet in the interim, which is a key difference in the way Mt. Gox was handled.

Also, the bitcoin price didn’t tank in response to the Bithumb hack. It traded lower for a while, but less than 24 hours it was back in the green, which is a reflection of the fact that bitcoin trading is no longer dependent on a single exchange.

Charlie Lee, creator of Litecoin (LTC), the No. 6 cryptocurrency by market cap, was among the first to respond to the Bithumb hack. He tweeted:

Indeed, Bithumb does expect to be able to cover the losses via their reserves.

Crypto Security

It’s still early on in Bithumb’s security breach, and more details are sure to emerge in time. In the meantime, it’s a good idea to use the hack as an opportunity to examine the security of your cryptocurrency investment portfolio. There are several hardware wallet options out there for you to choose from — whether it’s Trezor or Ledger Nano S, to name a couple — and as Charlie Lee advised, “only keep on exchange coins that you are actively trading.”
