Cryptocurrency-mining bot targets devices with SSH service

Target: Internet of Things (IoT) devices that have an open Remote Desktop Protocol (RDP) port.

Attack Vector: Cryptocurrency miner.
Summary: A newly discovered cryptocurrency-mining bot is targeting Internet of Things (IoT) devices that have an open Remote Desktop Protocol (RDP) port, enabling it to exploit vulnerable devices. Not only are attackers targeting IoT connected devices, they are also capable of carrying out cryptocurrency mining in the background. The IP related to the attack has been identified as, which is based in the US, California, and connected to the organisation Vivid Hosting. It has seen to be typically landing on port 22, an SSH service. This implies the attack could be applicable to all servers and connected devices with a running SSH service.
Risk assessment summary: This threat has been assessed as 3c MODERATE. If successful, the attacker can install a cryptocurrency miner on to a device using social engineering tactics. Once the miner has been installed, the attackers can funnel profit, in the form of Monero and Ethereum cryptocurrency, over to a scam website. However, the likelihood of infection is mitigated by employing good security practices to protect against phishing or embedded email delivered malware.


Ripple is a payment system and a digital currency which evolved completely independently of Bitcoin. Although Ripple holds the second highest market cap after Bitcoin, there are surprisingly no studies which analyze the provisions of Ripple. In this paper, we study the current deployment of the Ripple payment system. For that purpose, we overview the Ripple protocol and outline its security and privacy provisions in relation to the Bitcoin system. We also discuss the consensus protocol of Ripple. Contrary to the statement of the Ripple designers, we show that the current choice of parameters does not prevent the occurrence of forks in the system. To remedy this problem, we give a necessary and sufficient condition to prevent any fork in the system. Finally, we analyze the current usage patterns and trade dynamics in Ripple by extracting information from the Ripple global ledger. As far as we are aware, this is the first contribution which sheds light on the current deployment of the Ripple system.

xCurrent Ripple’s software that provides API-based messaging and transaction settlement based on an open, neutral protocol of value transfer between different ledgers and networks.

Solution Components

Messenger: – Messenger is an API-based messaging module that enables bidirectional communication between connected RippleNet banks. It connects to the beneficiary bank’s instance of Messenger to exchange KYC and risk information, fees, FX rates (if applicable), payment details and expected time of funds delivery. It packages this information and presents the entire cost structure to the originating bank, providing unprecedented visibility into the total cost of the transaction. If information is incorrect or missing, transacting parties will find out before initiating the transaction, drastically increasing straight through processing (STP) rates. Once the sender approves the transaction, Messenger employs ILP to settle funds and notifies all parties of the transaction confirmation.

Validator: – Validator is a component that cryptographically confirms the success or failure of a payment. It coordinates the funds movement across the ledgers of transacting parties in a way that removes all settlement risk and minimizes delays in settlement. Validator provides the single source of truth for the transacting counterparties regarding the success or failure of a payment.

FX Ticker: – FX Ticker is the component of xCurrent that facilitates the exchange between ledgers by enabling liquidity providers to post FX rates. This component provides the exchange rate between any pair of ledgers that it is configured with. Additionally, it keeps track of the account, currency and authentication credentials for each configured ILP Ledger. During the transaction, it coordinates transfers on ILP Ledgers for settlement, ensures the validity of an FX quote and transfers the payment amount to the beneficiary bank’s ILP Ledger.

ILP Ledger: – ILP Ledger is a sub ledger of each transacting bank’s general ledger. This component of xCurrent is utilized to the track the credits, debits and liquidity across the transacting parties. ILP Ledger enables transacting parties to settle funds atomically, which means the entire transaction settles instantly or not at all — no matter how many parties are involved. The ability to atomically settle enables new, low-value offerings through the ability to send real-time payments as the settlement of funds happens in milliseconds. Further, the settlement risk is eliminated because the payment processes entirely or fails upfront. ILP Ledger is designed to provide transacting banks with 24/7, on-demand availability. The combination of these capabilities allows banks to profitably offer low-value, on-demand international payments products and services.

Key Benefits

 Enhance Customer Acquisition and Retention

By delivering new products and services to retail and corporate customers — featuring high-speed, on-demand, cost-effective and traceable global payments — in both assisted and unassisted channels, it provides an opportunity re-engage and retain existing customers. xCurrent’s frictionless payment experience mitigates disintermediation from online, non-bank payment providers. The solution is a key competitive advantage and promotion-worthy offering to drive customer acquisition. Enhance Customer Acquisition and Retention

Lower Operational Costs

With xCurrent’s bidirectional messaging, banks can more efficiently exchange information regarding the sender, receiver, fees, rates, and delivery estimate and payment status to lower their operational cost of processing international payments. Payment processing costs are significantly reduced through xCurrent’s ability to increase STP rates and eliminate SWIFT fees. Treasury operations costs are decreased by lowering in-flight capital requirements, liquidity costs, counter party risk and compliance costs. Reconciliation costs are reduced due to xCurrent’s ability to provide instant confirmation and real-time liquidity monitoring.

Bitcoin Gold

What is Bitcoin Gold (BTG)

Bitcoin Gold (BTG) is a fork of the Bitcoin block chain. At block 491407, Bitcoin Gold miners will begin creating blocks with a new proof-of-work algorithm, and this will cause a bifurcation of the Bitcoin block chain. The original Bitcoin block chain will continue on unaltered, but a new branch of the block chain will split off from the original chain. The new branch is a distinct block chain with the same transaction history as Bitcoin up until the fork, but then diverges from it. As a result of this process, a new cryptocurrency is born and we gave it a name BITCOIN GOLD (BTG).

What is the purpose of Bitcoin Gold?

The purpose of Bitcoin Gold is to make Bitcoin mining decentralized again. Satoshi Nakamoto’s idealistic vision of “one CPU one vote” has been superseded by a reality where the manufacture and distribution of mining equipment has become dominated by a very small number of entities, some of which have engaged in abusive practices against individual miners and the Bitcoin network as a whole. By changing Bitcoin’s proof-of-work algorithm from SHA256 to Equihash, all of the specialized SHA256 mining equipment will be obsolete for mining the Bitcoin Gold blockchain. Thus, Bitcoin Gold will provide an opportunity for countless new people around the world to participate in the mining process with widely-available consumer hardware that is manufactured and distributed by reputable mainstream corporations. A more decentralized, democratic mining infrastructure is more resilient and more in line with Satoshi’s original vision.

How can I get Bitcoin Gold?

The Bitcoin Gold (BTG) initial coin distribution method is almost exactly the same as that used by the Bitcoin Cash fork of August 1. Everyone who held Bitcoin when block 491406 was mined automatically received Bitcoin Gold at the rate of 1 BTC = 1 BTG. (If you had 20 BTC at the time of the fork, you now also have 20 BTG.)

What wallet should I keep my BTC in to make sure I will receive BTG?

Some wallets may offer you direct access to your BTG, while others may require you to take additional technical steps. Verified wallets that support BTC and BTG side-by-side will be listed on the Bitcoin Gold home page. We will publish guides for retrieving BTG from the most popular wallets, including Bitcoin Core, Electrum, Mycelium, hardware wallets, paper wallets, and more.
