It all started in with a paper on the first decentralized digital currency, Bitcoin, created by an unknown person or persons referred to as Satoshi Nakamoto. Bitcoin is a peer-to-peer currency based on cryptography that works on distributed ledger technology known as blockchain. In , the first open-source software for Bitcoin was released. The main advantage of Bitcoin is its decentralized nature; however, this also makes it impossible to control or censor by any single authority, making Bitcoin attractive to cybercriminals.
Over time, more than 4, similar cryptocurrencies, also known as altcoins, have emerged and, as a result, the use of malware that targets bitcoins or altcoins for financial gain has been on the rise. Two cryptocurrencies that have become popular among cybercriminals due to their privacy features and untraceable nature are Zcash and Monero.
In this blog, ThreatLabZ provides an insight of various cryptominers and stealer malware variants that are taking advantage of rising cryptocurrency prices and popularity. ThreatLabZ researchers have categorized malware payloads related to cryptocurrency into the following three categories:.
While a single system capable of calculating approximately hashes per second is not useful for mining, a botnet of , similar hosts can produce 10,, hashes per second. Authors of most crypto-malware, new or old, download original or slightly modified versions of legitimate and open source-mining software rather than writing their own mining malware. In the beginning of our research, we only observed bitcoin miners, but now Monero tops the list of cryptocurrencies mined by malware.
Cryptominers have been targeting all types of operating systems, such as Windows, Linux, OSX, and even Android and IoT devices, despite their low processing power. Cybercriminals have also targeted servers by exploiting various vulnerabilities to install cryptominers. Cryptomining trends have been growing dramatically since cryptocurrency prices hit an all time high in late In fact, according to ThreatLabZ analysis, cryptomining has outgrown ransomware to become one of the top threats in Cryptocurrencies such as bitcoins are not stored in wallets as some people might think.
Bitcoins are stored in blockchain which is distributed via a public ledger. Cryptocurrencies work on the concept of public key cryptography, where a public key is the wallet address used to receive money, while a private key is kept secret in wallet files and is required to spend money.
So, in simple terms, wallets only store credentials to access or spend money stored in blockchain and owned by the user.
Wallet stealers have been around for almost as long as cryptominers. In fact, the first bitcoin wallet stealer was documented just three months after the first cryptominer. Over time, some very simple malware emerged whose only function was to steal wallet. Some generic and popular infostealer malware variants, like Pony and Azorult, also have the capability to steal cryptocurrency wallets and passwords amongst their long lists of tools. Cybercriminals always come up with innovative ways to profit.
Clipboard hijacking for replacing crypto-addresses is one of their innovative and subtle methods. Cryptocurrency wallet addresses are cryptographically generated, random-looking sequences of alphanumeric characters. They are not easy to remember, and that works to the advantage of bad actors. In April , a Reddit user posted about the first clipboard hijacker malware, which was a Chrome extension posing as the Dogecoin ticker extension.
Over the years, many clipboard hijacker variants have emerged. Some just replace a bitcoin address with one hardcoded address, while others can replace a bitcoin address with a similar-looking address from as many as 10, embedded addresses. Some target only one currency, while others target more than 13 currencies. As with miners and wallet stealers, there is some standalone clipboard hijacker malware in the news, such as ComboJack and CryptoShuffler, and there is multipurpose malware also capable of clipboard hijacking, such as Evrial and NjRAT Lime , which we recently blogged about.
A variant of Phorpiex, an old and popular worm, was spotted with clipboard hijacking capability instead of the spamming functionality for which it is known. Technical details given below. There have also been some malware variants that did not try to add new functionality, but used existing features, such as keylogging, web injects, and overlay attacks to steal cryptocurrencies. Below are few examples:. Around September , banking malware Dridex was seen targeting cryptocurrency-related software, searching filesystem paths and lists of processes to inject keyloggers.
This functionality already existed in Dridex and was configured to target cryptocurrency-related tools along with its traditional targets. In August , TrickBot, a traditional banking malware variant with version and group tag tt started targeting coinbase. Six months later, in February , another TrickBot variant with version and group tag kas2 again targeted crypto-exchanges with dynamic WebInjects for coin purchasing pages.
These are Android malware variants with the ability to detect the top open window of applications and phish credentials for that app by showing a static or dynamically fetched overlay to the user.
Initially developed for targeting banking apps, these are also used to steal cryptocurrencies. Phorpiex, also known as Trik SDBot fork , is a decade-old botnet known for its worming and spamming capabilities.
It used to spread via Skype, but for some time it has been spread using email spam and removable drives. It began showing interest in coinminers some time back and has been downloading various coinminers along with other malware on systems infected with Phorpiex.
It also downloaded a Monero miner payload with following configuration. Recently, we came across Phorpiex v6. Phorpiex monitors for 14 cryptocurrencies and if the address format for any cryptocurrency is detected, it replaces that with a corresponding address from a hardcoded list.
Some time back, we came across two malware strains targeting Brazilian users. The malware contains code from multiple open-source projects, which they use to carry out the malicious activity. They also contain multiple references to characters or objects in Lord of the Rings. The following are open-source projects used by loader and final payload. Complete technical details are beyond the scope of this blog.
Along with targeting multiple banking sites for traffic interception using Fiddler, the malware targets some websites for keywords related to a bitcoin wallet, address, etc. It also steals credentials for digital currency wallet like mercadobitcoin. EngineBox use a clipboard change event handler, which checks whether data copied to a clipboard is a bitcoin address.
The last transaction of this bitcoin address was on The attacker is constantly moving money out of this address as soon as it is received. Transactions on this bitcoin address are shown in the screen below:. Kasidet is multipurpose malware also known as Neutrino, a bot that was first observed being advertised on a hacking forum in December It was seen downloading coinminers on infected systems starting late Coinminer details are as follows:.
As more people are getting familiar with and starting to use or invest in cryptocurrencies, the awareness and pervasiveness of cryptocurrencies in everyday life will continue to rise.
In spite of their initial resistance to cryptocurrencies, more and more governments are realizing the potential of cryptocurrencies and the underlying blockchain technology in the digital era. As a result, we will see an increase in crypto-malware. The Zscaler ThreatLabZ research team will continue to monitor and analyze these threats with a goal to provide protection against them.
URL: Cryptocurrency miners and stealers have been around for a few years, but have grown in number with the surge in cryptocurrency value. Cybercriminals have taken notice of the increasing worth and have begun adding support for cryptomining as well as stealing capabilities to existing malware families.
Cryptomining malware is a direct source of income for cybercriminals, unlike information-stealing malware, which involves the cybercriminal stealing the information and then the added step of having to sell or use the stolen information for indirect financial gain.
Here is how to do that. It's now seven years on, and we have more work than ever to do. Even when they are offline. This game is so good, easily the best out there. Once you found the item you like on Skinport, buying is convenient, cheap and fast. Eg, "-u Steve. Dogeminer 2 save file.
Mapped: Facebook’s Path to Social Network Domination (2008-2020)
For the first time, Russian private investors bought two small power plants to create a data center and a farm for mining cryptocurrency. Moreover, one by one, many states decided to create national electronic money systems, fearing to "fall out" of the race for the title of "the most dynamic modern economy". The market of cryptocurrencies today is equal in capitalisation to such companies as the Japanese network provider NTT Docomo, the oilfield services company Schlumberger, the Royal Bank of Canada, and the Japanese telecommunication carrier Nippon Telegraph. In Dubai, for example, state cryptocurrency has already been launched, and blockchain technology is planned to be used in all state structures by It is already used in bond transfers, money transfers, payment processes and trading platforms. Transactions are processed quickly, safely and more cost-effective. The Central Bank of Russia is also ready to use blockchain technologies to provide financial services, however, the legalization of already existing cryptocurrencies is considered inexpedient. Last year President of Russia, Vladimir Putin instructed the government and the Bank of Russia to prepare amendments to the legislation of mining, placement of cryptocurrencies, and determining the status of digital technologies used in the financial sphere.

One of the largest crypto currency mining farms opened Thursday in Yerevan. He said that around 40 guests are expected to come to Armenia in the next two days. They will also meet with representatives of the government to learn opportunities for greater investments in the country. Now 3, machines producing bitcoins and Ethereum operate in the mining farm. The number of machines are planned to be increased to ,

The theme of the conference The First Digital Industry Business Portal is a convenient communication platform for meetings and communication of experts and professionals in the field of digital transformation of industry. This joint initiative is being implemented by the Ctrl2GO Group of Companies, one of the leaders in the field of digitalization, and the leading Russian publisher of corporate
The parts of the O2O JV Samokat e-grocery delivery, Delivery Club food delivery and Citimobil taxi service play an important role in Sberbank's ecosystem, VTBC notes, but sees the "divorce of the two partners was only a matter of time". The sale of the stake in MF Technologies was seen as positive for Sberbank, by VTBC, as this will allow it to reroute funds to other ecosystem projects, including e-commerce platform Sbermegamarket, in order to reach its ambitious strategic targets. Sova also believes that Sber selling the share "gives credence" to previous media reports that the Sber and Mail. The analysts at Sova see the news as marginally negative for both VK and Sber. For VK, repeated changes in key shareholders typically do little to help a company stay on track.
Other sections. The situation gets even worse when you go somewhere other than the official store — fake applications, limited security checks, and so on. However, the spread of malware targeting Android OS is not limited to unofficial stores — advertising, SMS-spam campaigns and other techniques are also used. Among this array of threats we found a rather interesting sample — Trojan. This Trojan boasts a complicated modular architecture that means it can conduct a variety of malicious activities: mine cryptocurrencies, annoy users with constant ads, launch DDoS attacks from the affected device and much more. Samples of the Loapi family are distributed via advertising campaigns.
