Nasty Cr1ptT0r Ransomware: Threat to NAS
What is Network Attached Storage and why is it targeted?
Network attached storage (NAS) is a devoted file storage that allows more than one user and heterogeneous client devices to recover data from centralized disk capacity. NAS devices are do not have a keyboard or display they are configured and managed with a browser-based utility. NAS devices are typically linked to servers running Linux operating system.
Due to vulnerabilities detected and old firmware in D-Link DNS 320 it is exploited by cybercriminals. The device was exposed to WAN through 8080 ports, FTP port 21 and a range of ports for port forwarding. Not only this in 2023, a hard-coded backdoor was also noticed in this router. This backdoor permitted hacker to gain unauthorized access for victim’s network.
An unpatched device is ripe target for attack
What is Cr1ptT0r?
Cr1ptT0r is an encryption Trojan ransomware that seems to target Network Assigned Storage (NAS) devices.
The malware then saves two plain text files in victims machine, one is the ransom note called “_FILES_ENCRYPTED_README.txt,” that provides information about how victim can reach the ransomware operator to pay ransom, receive decryption key and know what is happening with the system.
Second file is named “_cr1ptt0r_support.txt” and it has the address of a website in the Tor network. If victims fail to understand what they should do they can use this support URL.

Due to its ability to infect embedded systems and the possibility to adapt its code to infect Windows machines Cr1ptT0r is a treacherous threat.
What all devices are targeted by Cr1ptT0r?
The new ransomware strain is targeting several types of D-Link devices that are connected to the Internet in a manner that is not secure and has known vulnerabilities or do not support the latest firmware or is security patched.
Do I need to pay ransom to get my data back?
As of writing, ransomware operator allows victim to unlock one file for free. After which victim who want to get the data need to pay ransom and provide Cr1ptT0r with the type and firmware version of the device. Once the ransom is paid victim receives a script to decrypt files.
Moreover, victim can get decryption from OpenBazaar marketplace, for BTC 0.30672023 (about $ 1,200). If target wants to unlock any specific file, then by paying $19.99 this can be done. In such a case the file needs to be sent to the operator.
Apart from this, Bleeping Computer noticed that the operators also offer decryption key for Synolocker ransomware that made headlines in 2014 for the same price.
Don’t even think for a second that you are secure. A flaw in your device or network security can make you a victim. Therefore, to stay protected from such unforeseen attacks always keep backup of your important data. Plus, run an updated anti malware on your system like Systweak’s Advanced System Protector.

What Should Developers Know About Threat Modeling?
Threat modeling is a process that very few developers seem to pursue. However, it is a process that helps you and your entire team to model all potential threats to model all possible risks to your application. This process has become essential for optimizing network security by recognizing objectives, vulnerabilities, and developing measures to prevent the effects of threats towards the system. The threat is something that can be malicious to your organization and data systems. Like for example, incidental occurrences such as the failure of a storage device which can compromise the integrity of the entire organization. Now, let’s read the remaining part of the article to get more insight into this topic.
Importance of Threat Modeling:Threats are one of the most significant factors that compel companies to spend $89.1 billion only on enterprise security solutions.
Assessment ScopeIn this step, you need to understand the price of what’s at stake. Recognizing tangible assets, like databases of information or sensitive files, is usually straightforward, and realizes the capabilities provided by the application.
Identify Possible Attacks/Threats Prioritizing Identified RisksOnce identified, risk management can be prioritized. For every threat, determine potential outcomes and the impact of those to understand how to reduce these issues. Also, look for ways to mitigate any future risks. Although many of the threats might appear to be security-related, and others might have more natural explanations. Threat assessments also include power outages and even a flooded server room. All these factors can lead to severe threats to your enterprise.
What’s the Best Time to Model the Threat?The most suitable time to model the threat is at the beginning of a project. However, it’s better to conduct a threat modeling project halfway by a project or even at the end than not at all. To model, the threat at the end of a project can be beneficial, like understanding the architecture and how data flows through it. But, threat modeling at the end of a project can lead to finding more work which might require to fix poor design decisions that were not caught at the beginning. Those entering into threat modeling, remember to conduct the first session on your existing project, letting you experiment with a threat modeling session so that you can familiarize yourself with everything required. By doing so, you will better analyze all assets and the flow of data to assess the risks. Once the process is hit out, you’ll have a better chance of getting successful in your new project of threat modeling. Moreover, you will also be prepared for threats that might exist in the design phase of the project. From here, you might begin to take into account threats during the initial design of a brand new feature.
How to Approach the Threat Model?Then you need to understand who the users are within the administrators, regular system users, outsourced contractors and perhaps potential hackers with apps or other tools looking for vulnerabilities within your network. There are other actors, too, which includes disgruntled former employees. Defining the user’s actors is vital as missing a group can indicate that you might be missing an entire category of threats. Also, consider the
The Flow of Data and Information:At this point of threat modeling, track each of the different data flow running through the system. For each of them, you need to know where the data goes. What does it interact with along the way? Later look to identify where data can leak or where it might get exposed. More data components mean more opportunities for a hacker to gain access to the information. While individual data means that the information flows differently based on the architecture and the specific situation. One example might include a request from a user’s browser where the cookie is sent through and interacts with multiple components as it does. Search for opportunities for each data flows for any actors to get hold of valuable information. If something makes you frown, step back through the process and move that threat through until you can mitigate the frowning moment.
Threat List Complete:When the list gets completed, prioritize the list from unlikely to improbable to not likely. No matter what is the probability of the risk, work through the risk as a real possibility. When you have the risk list then manage the threats by the following ways: • Accepting: If the risk is shallow, recognize the potential impact. It is also possible that you will find the potential negative user impact, and you can also reassess it later. • Transferring: Maybe another team is responsible for managing a particular risk. If that team picks up the defense quickly so, outsource it. • Avoiding: Consider the complete structural changes to your data flow to avoid risks. It might also mean that architectural changes are required to kill a particular feature so as not to prevent the danger. • Reducing: Take all possible actions to lower the risk by lessening the impact of the risks. You may need to take multiple steps to reduce the threat. Great efforts are required to mitigate the risks.
Final Thoughts:Don’t stop once the threat modeling is completed. Keep working because of threats and actors’ changes with time. Make a list of all potential issues or risks that must be addressed and incorporate them into your plan. Also, remember that you should be careful with whom you are sharing your threat modeling plan. It is essential because you never know where that information might end up, or who might be a threat to your data and organization.

How To Use Big Data To Avoid Building Highways To Hell

The research uses data on biodiversity, climate, transportation, and crop yields to draft a color-coded mapping system indicating where new road projects should go to provide the most benefits for food production, while being the least harmful to the environment.

“In developing countries, post-harvest losses of food are a big problem, and much of this is because of poor infrastructure,” Phalan says. “Imagine what traveling all day under the hot sun in the back of a truck over an unpaved, potholed road can do to a crate of tomatoes or soft fruits. In West Africa, I have seen piles of oranges left to rot in the orchards where they were produced because it was too difficult and costly to get them to market while they were still fresh.”
The scientists focused their study on the Greater Mekong in Southeast Asia, one of the most biologically significant parts of the Earth—and a region that has lost almost a third of its tropical forests since the 1970s.

The area includes Vietnam, Laos, Cambodia, Thailand, Myanmar, and the Yunnan province of China. It has an estimated 20,000 plant species, 2,000 types of land vertebrates and 850 species of freshwater fish, much of which are not found anywhere else in the world. Plus, the region’s massive forests act as “carbon sinks,” absorbing greenhouse gases.
“The approach and tools need to be modified according to local, national and regional priorities, but I think could be applicable to other regions, including the United States,” says Xu. “Most infrastructure in the United States was built decades ago, if not a century ago, so there is an imperative to update road networks.”

The researchers used computer mapping software to overlay maps showing yield gaps — the difference between current crop yields and what could be produced using improved farming methods.
“The approach taken in our study provides a sort of initial screening of where it might be most environmentally problematic to build new infrastructure,” Phalan says, adding that it would still be necessary for individual projects to undergo an environmental impact statement to find issues not detected in the preliminary look.
“Government planning policy can help,” he says. “For example, in the United States, large areas are designated ‘roadless’ areas, which helps to keep human impacts in such areas low. Finance is another mechanism. Major lenders, such as the International Finance Corporation, are increasingly requiring developers to commit to environmental standards that protect species and habitats.”
The tools highlighted in this study “help pinpoint the projects we should oppose most loudly, while transparently showing the reasons why, and providing alternatives where environmental costs are lower and development benefits are greater,” Xu says. “Conservationists need to be active voices in infrastructure development. I think these approaches have the potential to change the tone of the conversation.”
