This dataset includes labels that explain the linkages between flows connected with harmful or possibly malicious activity to provide network malware researchers and analysts with more thorough information. These labels were painstakingly created at the Stratosphere labs using malware capture analysis.

We present a concise explanation of the labels used for the identification of malicious flows, based on manual network analysis, below:

Attack: This label signifies the occurrence of an attack originating from an infected device directed towards another host. Any flow that endeavors to exploit a vulnerable service, discerned through payload and behavioral analysis, falls under this classification. Examples include brute force attempts on telnet logins or header-based command injections in GET requests.

Benign: The "Benign" label denotes connections where no suspicious or malicious activities have been detected.

C&C (Command and Control): This label indicates that the infected device has established a connection with a Command and Control server. This observation is rooted in the periodic nature of connections or activities such as binary downloads or the exchange of IRC-like or decoded commands.

DDoS (Distributed Denial of Service): "DDoS" is assigned when the infected device is actively involved in a Distributed Denial of Service attack, identifiable by the volume of flows directed towards a single IP address.

FileDownload: This label signifies that a file is being downloaded to the infected device. It is determined by examining connections with response bytes exceeding a specified threshold (typically 3KB or 5KB), often in conjunction with known suspicious destination ports or IPs associated with Command and Control servers.

HeartBeat: "HeartBeat" designates connections where packets serve the purpose of tracking the infected host by the Command and Control server. Such connections are identified through response bytes below a certain threshold (typically 1B) and exhibit periodic similarities. This is often associated with known suspicious destination ports or IPs linked to Command and Control servers.

Mirai: This label is applied when connections exhibit characteristics resembling those of the Mirai botnet, based on patterns consistent with common Mirai attack profiles.

Okiru: Similar to "Mirai," the "Okiru" label is assigned to connections displaying characteristics of the Okiru botnet. The parameters for this label are the same as for Mirai, but Okiru is a less prevalent botnet family.

PartOfAHorizontalPortScan: This label is employed when connections are involved in a horizontal port scan aimed at gathering information for potential subsequent attacks. The labeling decision hinges on patterns such as shared ports, similar transmitted byte counts, and multiple distinct destination IPs among the connections.

Torii: The "Torii" label is used when connections exhibit traits indicative of the Torii botnet, with labeling criteria similar to those used for Mirai, albeit in the context of a less common botnet family.

This dataset is part of my PhD research on malware detection and classification using Deep Learning. It contains static analysis data: Top-1000 imported functions extracted from the 'pe_imports' elements of Cuckoo Sandbox reports. PE malware examples were downloaded from virusshare.com. PE goodware examples were downloaded from portableapps.com and from Windows 7 x86 directories.

This dataset is created to form a Balanced URLs dataset with the same number of unique Benign and Malicious URLs. The total number of URLs in the dataset is 632,508 unique URLs.

The creation of the dataset has involved 2 different datasets from Kaggle which are as follows:

First Dataset: 450,176 URLs, out of which 77% benign and 23% malicious URLs. Can be found here: https://www.kaggle.com/datasets/siddharthkumar25/malicious-and-benign-urls

Second Dataset: 651,191 URLs, out of which 428103 benign or safe URLs, 96457 defacement URLs, 94111 phishing URLs, and 32520 malware URLs. Can be found here: https://www.kaggle.com/datasets/sid321axn/malicious-urls-dataset

To create the Balanced dataset, the first dataset was the main dataset, and then more malicious URLs from the second dataset were added, after that the extra Benign URLs were removed to keep the balance. Of course, unifying the columns and removing the duplicates were done to only keep the unique instances.

For more information about the collection of the URLs themselves, please refer to the mentioned datasets above.

All the URLs are in one .csv file with 3 columns: 1- First column is the 'url' column which has the list of URLs. 2- Second column is the 'label' which states the class of the URL wether 'benign' or 'malicious'. 3- Third column is the 'result' which also represents the class of the URL but with 0 and 1 values. {0 is benign and 1 is malicious}.

In recent years, with the development of the Internet, the attribution classification of APT malware remains an important issue in society. Existing methods have yet to consider the DLL link library and hidden file address during the execution process, and there are shortcomings in capturing the local and global correlation of event behaviors. Compared to the structural features of binary code, opcode features reflect the runtime instructions and do not consider the issue of multiple reuse of local operation behaviors within the same APT organization. Obfuscation techniques more easily influence attribution classification based on single features. To address the above issues, (1) an event behavior graph based on API instructions and related operations is constructed to capture the execution traces on the host using the GNNs model. (2) ImageCNTM captures the local spatial correlation and continuous long-term dependency of opcode images. (3) The word frequency and behavior features are concatenated and fused, proposing a multi-feature, multi-input deep learning model. We collected a publicly available dataset of APT malware to evaluate our method. The attribution classification results of the model based on a single feature reached 89.24% and 91.91%. Finally, compared to single-feature classifiers, the multi-feature fusion model achieves better classification performance.

Dataset consisting of feature vectors of 215 attributes extracted from 15,036 applications (5,560 malware apps from Drebin project and 9,476 benign apps). The dataset has been used to develop and evaluate multilevel classifier fusion approach for Android malware detection, published in the IEEE Transactions on Cybernetics paper 'DroidFusion: A Novel Multilevel Classifier Fusion Approach for Android Malware Detection'. The supporting file contains further description of the feature vectors/attributes obtained via static code analysis of the Android apps.

An October 2023 phishing simulation carried out at worldwide organizations found that the highest share of employees clicking on malicious links and submitting passwords were in the North America, with over ** percent of them doing so. Europe ranked second, with **** percent, followed closely by Asia and the Pacific region.

Introduction

This study seeks to obtain data which will help to address machine learning based malware research gaps. The specific objective of this study is to build a benchmark dataset for Windows operating system API calls of various malware. This is the first study to undertake metamorphic malware to build sequential API calls. It is hoped that this research will contribute to a deeper understanding of how metamorphic malware change their behavior (i.e. API calls) by adding meaningless opcodes with their own dissembler/assembler parts.

Malware Types and System Overall

In our research, we have translated the families produced by each of the software into 8 main malware families: Trojan, Backdoor, Downloader, Worms, Spyware Adware, Dropper, Virus. Table 1 shows the number of malware belonging to malware families in our data set. As you can see in the table, the number of samples of other malware families except AdWare is quite close to each other. There is such a difference because we don't find too much of malware from the adware malware family.

Figure shows the general flow of the generation of the malware data set. As shown in the figure, we have obtained the MD5 hash values of the malware we collect from Github. We searched these hash values using the VirusTotal API, and we have obtained the families of these malicious software from the reports of 67 different antivirus software in VirusTotal. We have observed that the malicious software families found in the reports of these 67 different antivirus software in VirusTotal are different.

Description

The datasets demonstrate the malware economy and the value chain published in our paper, Malware Finances and Operations: a Data-Driven Study of the Value Chain for Infections and Compromised Access, at the 12th International Workshop on Cyber Crime (IWCC 2023), part of the ARES Conference, published by the International Conference Proceedings Series of the ACM ICPS.

Using the well-documented scripts, it is straightforward to reproduce our findings. It takes an estimated 1 hour of human time and 3 hours of computing time to duplicate our key findings from MalwareInfectionSet; around one hour with VictimAccessSet; and minutes to replicate the price calculations using AccountAccessSet. See the included README.md files and Python scripts.

We choose to represent each victim by a single JavaScript Object Notation (JSON) data file. Data sources provide sets of victim JSON data files from which we've extracted the essential information and omitted Personally Identifiable Information (PII). We collected, curated, and modelled three datasets, which we publish under the Creative Commons Attribution 4.0 International License.

1. MalwareInfectionSet We discover (and, to the best of our knowledge, document scientifically for the first time) that malware networks appear to dump their data collections online. We collected these infostealer malware logs available for free. We utilise 245 malware log dumps from 2019 and 2020 originating from 14 malware networks. The dataset contains 1.8 million victim files, with a dataset size of 15 GB.

2. VictimAccessSet We demonstrate how Infostealer malware networks sell access to infected victims. Genesis Market focuses on user-friendliness and continuous supply of compromised data. Marketplace listings include everything necessary to gain access to the victim's online accounts, including passwords and usernames, but also detailed collection of information which provides a clone of the victim's browser session. Indeed, Genesis Market simplifies the import of compromised victim authentication data into a web browser session. We measure the prices on Genesis Market and how compromised device prices are determined. We crawled the website between April 2019 and May 2022, collecting the web pages offering the resources for sale. The dataset contains 0.5 million victim files, with a dataset size of 3.5 GB.

3. AccountAccessSet The Database marketplace operates inside the anonymous Tor network. Vendors offer their goods for sale, and customers can purchase them with Bitcoins. The marketplace sells online accounts, such as PayPal and Spotify, as well as private datasets, such as driver's licence photographs and tax forms. We then collect data from Database Market, where vendors sell online credentials, and investigate similarly. To build our dataset, we crawled the website between November 2021 and June 2022, collecting the web pages offering the credentials for sale. The dataset contains 33,896 victim files, with a dataset size of 400 MB.
