Cryptojacking software group

In simple terms, miners use computational resources to perform calculations, which involve iterating through billions of random inputs, until a desired output is achieved. Since mining uses a lot of processing power, cyber-criminals have found a way to get their victims to mine the coins on their behalf, often without them knowing. They are able to do this by infecting a vulnerable server with a type of malware that runs the mining program. Each time a user visits an infected website, the program is installed on their device, where it runs in the background mining the coins.

Joao Correia. Cyberattacks come in all shapes in sizes. At other times, an attacker is trying to achieve a goal that is not necessarily intended to cause your organization any harm. Sometimes malware simply sits on your computing infrastructure, quietly performing its job without immediately causing obvious damage — but it still drains your resources, essentially acting as a black hole. This type of malware will cost you a ton of money, but it also risks significant reputational damage.

Worse, this malware is hiding in one of the most unlikely locations: your SQL database. Content: 1. Cryptojacking 2. Why cryptojacking will cost you 3. Understanding PostgreSQL 4. A PostgreSQL vulnerability that enables cryptojacking 5. Handling cryptojacking in the real world 7. Automated and live patching is key 8. Mining cryptocurrency can mean big money, but for cryptomining the facts on the ground have changed.

Not so long ago it was easy to mine large amounts of cryptocurrency just by using a standard computer with an internet connection — you could do it at home. However, that changed over the years because many popular cryptocurrency algorithms are designed in a way that means that mining coins become more difficult as time passes. The result is that today, mining coins is computationally extremely demanding — miners need a lot of resources to mine cryptocurrency, and resources are not free.

This hits profits and, in many cases, means that unless resources can be obtained for free — in other words, stolen — mining cannot be performed profitably. And that is what cryptojacking is all about — stealing resources to use for the purpose of cryptomining. Cryptojackers are motivated to stay hidden as long as they can, and they will of course try and inject their cryptojacking code where you are least likely to find it — we will come to that later in this article.

A hacker that installs cryptomining software on your systems does not do so to directly disrupt your operations nor to steal data — but the drain on your computing resources can be extremely expensive. There are other consequences too. We list some of the effects here:. But what is PostgreSQL, and do you even use it in your workloads?

These components operate in the background to support your applications. PostgreSQL is very popular in part because it is cheap to run and easy to implement. In December , a research team found the first example of hackers injecting cryptomining code into PostgreSQL. You can read a deep analysis from the team at Unit 42 , it explains the methodology used by PGMiner here.

Nonetheless, this feature is actively being exploited for cryptojacking. In this article , security vendor Imperva explains how hackers are injecting cryptomining code into PostgreSQL instances by making use of an image of Scarlett Johannsson. It sounds odd, yes, but essentially by appending malicious code to an image file, attackers can insert their code into a PostgreSQL instance via remote code execution.

The image is hosted on a public image hosting service and it looks like an image of a popular actor, nothing else — but this innocent image hides a real danger as it contains a real payload. According to the authors of the article, many anti-virus applications will not catch the payload in the image file. It goes to show that attackers have multiple avenues to inject cryptomining code just where they want it to be.

Worse, these exploits are currently out there in the wild — and attackers can use automated tools to find vulnerable PostgreSQL servers. Worse, in the case of CVE, there is currently no patch available. For example, minimizing or completely abolishing the use of superuser access in PostgreSQL and limiting what remote users can do. Another key point around best practice is the ability to consistently patch vulnerabilities. While CVE in itself does not currently have an associated patch, in the broad, patching closes the vulnerabilities that act as entry points for attackers — including those who try to install cryptomining code on your servers.

Notably, while many malware threats are restricted to a specific processor architecture, the PostgreSQL threats we discuss in this article are a threat across x86, ARM and MIPS processor architectures. We pointed to patching in the previous section — but there are difficulties associated with patching.

Patching consistently and effectively is particularly challenging. Tech teams sometimes do not prioritize patching, and rarely have the resources to roll out patches as fast as they can — nor to do so in a truly consistent manner. As so often is the case in cybersecurity, automation is the first step in getting patching done right. Patching automation lightens the workload for busy technology teams, while boosting consistency by virtue of automation.

But automation alone is not enough as patching often also involves disruption, and it can happen that teams put patching on hold because they are concerned that patching will lead to service breaks.

Live patching mitigates this issue by ensuring that patches can be applied without the need to restart servers. Live patching is not that widely available — and it is not always available for all the operating systems and services that your solutions depend on — such as PostgreSQL. We already deliver a live patching solution for important Linux OS distributions and indeed for key libraries in those distributions. Users of our live patching solutions for Linux server operating systems benefit because maintenance teams spend much less time applying patches — TuxCare applies patches automatically.

TuxCare also benefits server maintenance in that our automated, live patching solution applies patches on-the-fly.

Live patching means that critical security updates are installed without the need to restart a server — and without disrupting operations. This live, automated patching feature will soon be available for PostgreSQL databases and will mean that organizations that use TuxCare can significantly improve their PostgreSQL patching regime and therefore reduce many of the opportunities for malware injections — including cryptominers. To wrap up, you now know that profit-seeking hackers may be trying to hide cryptomining code in your servers — and indeed in your PostgreSQL database.

And it is not a threat that you can ignore — cryptomining software does not peacefully cohabit with your software solutions: it will drain your resources and will put you at risk of very significant costs.

Awareness is a good start, but you must also take action. Tighten up your PostgreSQL instances by limiting permissions, users and by patching consistently. Struggling to patch consistently? Subscribe to our newsletter to get the latest news on live patching technology from TuxCare Team.

Blog Open Source Enterprise Security. We list some of the effects here: Cost increases. We explained earlier that cryptomining is very resource-intensive. Cryptojacking upsets this balance, and it means that your workloads can suddenly fail — leading to unexpected outages. Where your billing is dependent on usage you can expect dramatically higher bills.

Physical damage. While your workloads are designed to run within the physical and environmental limits of your hardware, cryptojackers will show absolutely no concern when abusing your hardware via illicitly installed cryptomining software. It can lead to physical hardware failure as components such as CPUs are run beyond manufacturer and environmental limits. Compliance and legal concerns. Where an organization handles personal or other confidential data on its servers the presence of unauthorized cryptomining software can breach compliance regulations as the cryptomining software can have access to this data.

It can lead to significant legal problems. Cryptominers can become a security problem. Cryptojacking may start off as just an abuse of resources, but hackers can repurpose the software to accomplish other goals. This could be disrupting your services, or stealing data. In other words, a resource drain can quickly morph into a critical cyberattack.

Cryptojacking – Threat, Impacts and how to protect business from becoming a victim

As the value of cryptocurrencies, particularly Bitcoin, continues to surge, cybercriminals have invested in more cryptocurrency-related attack methods. It has become increasingly difficult to mine Bitcoin profitably and efficiently on commodity hardware such as laptops, smartphones, or desktop computers. One such example is Monero-Mining malware, which moves laterally across devices on an infected network. The malware uses laptops and workstations to profitably mine Monero cryptocurrency while deploying ransomware encryptions on affected devices. Free White Paper Darktrace. Although not as immediately profitable as ransomware, cryptomining can be secretly pursued in a target environment for months without causing evident business disruption or drawing attention. A botnet of infected devices mining cryptocurrency on multiple devices and targeting numerous organisations can go undetected by traditional security tools, allowing malicious actors to make a sustained profit.

The attacks result in the MrbMiner crypto-miner being installed onto the target servers, with the software apparently created, controlled.

WatchDog: Exposing a Cryptojacking Campaign That’s Operated for Two Years

Hackers are constantly learning, innovating and developing new attack methods — a phenomenon that crippled and embarrassed many organizations in Data breaches rose 45 percent last year, underlining the success of hacking innovations, with healthcare and banking racking up hits and the business sector weathering more than half of all breaches. To help companies better prepare for the year ahead, The Chertoff Group analyzed the cyber threat landscape to develop predictive cyber trends to watch in Why are we seeing such a concentration of cryptocurrency breaches? Cryptojacking is covert and highly profitable, affecting endpoints, mobile devices and servers: it runs in the background, quietly stealing spare machine resources to make significant profits with a low chance of detection. If the recent and explosive growth of ransomware indicates anything, it is that criminal organizations will continue to employ malware for profit. And, due to its ease of deployment, low-risk profile and profitability, TCG posits that this trend will continue to increase in While exploiting software flaws is a longstanding tactic used in cyberattacks, efforts to actively subvert software development processes are also increasing. Contrary to popular belief, software developers tend to be easy hacking targets. In a survey of U.

Both defendants are Iranian nationals believed to be living abroad. This is the first cryptojacking case to be prosecuted in the Eastern District of Missouri. Louis Division. Computing power is needed for a virtual master ledger that uses complicated algorithms to verify and record cryptocurrency transactions. Individuals or groups can dedicate their computer power and be rewarded with cryptocurrency.

An advanced persistent threat APT is a stealthy threat actor , typically a nation state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period.

Cryptojacking is a type of cybercrime that involves the unauthorized use of people's devices computers, smartphones, tablets, or even servers by cybercriminals to mine for cryptocurrency. Like many forms of cybercrime, the motive is profit, but unlike other threats, it is designed to stay completely hidden from the victim. Cryptojacking is a threat that embeds itself within a computer or mobile device and then uses its resources to mine cryptocurrency. Cryptocurrency is digital or virtual money, which takes the form of tokens or "coins. Cryptocurrencies use a distributed database, known as 'blockchain' to operate.

Introduction of Cryptojacking

Instances of cryptojacking malware have jumped more than percent since last year, a new report finds. A collaborative group of cybersecurity researchers called the Cyber Threat Alliance CTA published the report Wednesday, detailing the various and repercussions from cryptojacking — the illicit practice of hijacking a user's computer to mine cryptocurrencies. Most notably, CTA points out in the research that the number of instances of illicit mining malware found has sharply spiked in the months from the close of to end of July In the key findings document , the alliance points to a particular exploit that has been plaguing the security world for over a year, Eternalblue, as one of the leading causes. The CTA's analysis explains that a number of Windows operating systems remain vulnerable to the bug, despite a patch released by Microsoft.

It's been a productive afternoon for the entire team, but for one of your users it can be difficult for Endpoint Protection software to detect mining.

A guide to cryptojacking – how to prevent your computer from being turned into a money-making tool

Group-IB, an international company specializing in the prevention of cyberattacks, is recording new outbreaks of illegal mining cryptojacking threats in the networks of commercial and state organizations. Cryptojacking using computation capacity of a computer or infrastructure for cryptocurrency mining without the knowledge or consent of its owner is still a comparatively popular method of personal gain, in spite of a clear tendency toward a decrease in the number of incidents of this type of fraud. The low entry barrier to the illegal mining market results in a situation where cryptocurrency is being mined by people without technical expertise or experience with fraudulent schemes.

A powerful hardware-based threat detection technology is being integrated into a Microsoft enterprise security product to help protect businesses from cryptojacking malware. The problem with failing to foil cryptominers is that the cryptocurrency mined at these organizations is then used to fund other nefarious activities by criminal gangs or state-sponsored actors, Schrader maintained. Executing security tasks in a hardware module, as Microsoft and Intel are doing, has significant performance advantages, Das noted. TDT leverages a rich set of performance profiling events available in Intel SoCs system-on-a-chip to monitor and detect malware at its final execution point the CPU , he continued.

Step aside, ransomware. As you read previously on this blog, ransomware has become a booming industry , run somewhat like an MLM.

What are the steps you can take if you are cryptojacked

Cybercriminals are always on the lookout for clever ways to turn new technology into money-making opportunities — cryptojacking is just one of their latest innovations. Cybercriminals are always on the lookout for clever ways to turn new technology into money-making opportunities. Cryptojacking is one of their latest innovations. Although fairly recent, cryptojacking has already evolved into a complex threat model, coming in various flavors and targeting different types of physical and virtual devices. After the registration of every new block, an amount of new cryptocurrency is created and awarded to the miner that solved the validation equation first. Dedicated crypto-mining farms consist of large arrays of powerful computers to compete for cryptocurrency rewards and rake in billions of dollars every year.
