This document summarizes a research paper on classifying and extracting variants of malware. It discusses using both dynamic and static analysis to classify malware, including using entropy analysis to detect unpacking of packed malware. It proposes using control flow graphs and matching algorithms to perform malware classification and generate signatures to detect variants. The paper presents the methodology used, including generating signature trees and feature extraction. It evaluates classification algorithms like Naive Bayes, J48, and Random Forest on real and synthetic malware datasets. The conclusion is that the approaches can effectively identify malware variants and new malware is often a variant of existing malware.
Adware is a software that may be installed on the client machine for displaying advertisements for the
user of that machine with or without consideration of user. Adware can cause unrecoverable threat to the security
and privacy of computer users as there is an increase in number of malicious adware’s. The paper presents an
adware detection approach based on the application of data mining on disassembled code. This is an approach for
an accurate adware detection algorithm with adware data set and machine learning techniques. In this paper, we
disassemble binary files, generate instruction sequences and past his data through different data mining as well as
machine learning algorithms for feature extraction and feature reduction for detection of malicious adware.Then
system accurately detect both novel and known adware instances even though the binary difference between
adware and legitimate software is usually small.

Traditionally, "Cryptography" is a benediction to information processing and communications, it helps people to store information securely and the private communications over long distances. Cryptovirology is the study of applications of cryptography to build the malicious software. It is an investigation, how modern cryptographic tools and paradigms can be used to strengthen, develop and improve new malicious software attacks. Cryptovirology attacks have been categorized as : give malware enhanced privacy and be more robust against reverse-engineering, secondly give the attacker enhanced anonymity while communicating with deployed malware. This paper presents the idea of ``Cryptovirology'' which introduce a twist on how cryptography can also be used offensively. Being offensive means, it can be used to mount extortion based attacks that cause loss of access to information, loss of confidentiality, and information leakage, tasks which cryptography usually prevents. Also analyze threats and attacks that misuse of cryptography can cause when combined with fraudulent software (viruses, Trojans). Public-key cryptography is very essential for the attacks that based on cryptovirology. This paper also suggest some of the countermeasures, mechanisms to cope with and prevent such attacks. Even if the attackers actions on the host machine are being monitored, it still cannot be proven beyond reasonable doubt that he or she is the attacker; and it is an “originator-concealing attack”. Evidence should be collected from the “author’s own system which was used for the attack”. These attacks have implications on how the use of
cryptographic tools and techniques should be audited and managed in general purpose computing environments, and imply that access to the cryptographic tools should be in well control of the system(such as API routines). The experimental virus would demonstrate how cryptographic packages can be packed into a small space, which may have independent existence. These are many powerful attacks, where the attacker can encrypt the victim’s data for ransom and release it after hostage.
Limiting Self-Propagating Malware Based on Connection Failure Behavior csandit
Self-propagating malware (e.g., an Internet worm) exploits security loopholes in software to
infect servers and then use them to scan the Internet for more vulnerable servers. While the
mechanisms of worm infection and their propagation models are well understood, defense
against worms remains an open problem. One branch of defense research investigates the
behavioral difference between worm-infected hosts and normal hosts to set them apart. One
particular observation is that a worm-infected host, which scans the Internet with randomly
selected addresses, has a much higher connection-failure rate than a normal host. Rate-limit
algorithms have been proposed to control the spread of worms by traffic shaping based on
connection failure rate. However, these rate-limit algorithms can work properly only if it is
possible to measure failure rates of individual hosts efficiently and accurately. This paper points
out a serious problem in the prior method and proposes a new solution based on a highly
efficient double-bitmap data structure, which places only a small memory footprint on the
routers, while providing good measurement of connection failure rates whose accuracy can be
tuned by system parameters.
Replay of Malicious Traffic in Network TestbedsDETER-Project
In this paper we present tools and methods to integrate attack measurements from the Internet with controlled experimentation on a network testbed. We show that this approach provides greater fidelity than synthetic models. We compare the statistical properties of real-world attacks with synthetically generated constant bit rate attacks on the testbed. Our results indicate that trace replay provides fine time-scale details that may be absent in constant bit rate attacks. Additionally, we demonstrate the effectiveness of our approach to study new and emerging attacks. We replay an Internet attack captured by the LANDER system on the DETERLab testbed within two hours.

robust malware detection for iot devices using deep eigen space learningVenkat Projects
Internet of Things (IoT) in military settings generally consists of a diverse range of Internet-connected devices and nodes (e.g. medical devices and wearable combat uniforms). These IoT devices and nodes are a valuable target for cyber criminals, particularly state-sponsored or nation state actors. A common attack vector is the use of malware. In this paper, we present a deep learning based method to detect Internet Of Battlefield Things (IoBT) malware via the device’s Operational Code (OpCode) sequence. We transmute OpCodes into a vector space and apply a deep Eigenspace learning approach to classify malicious and benign applications. We also demonstrate the robustness of our proposed approach in malware detection and its sustainability against junk code insertion attacks. Lastly, we make available our malware sample on Github, which hopefully will benefit future research efforts (e.g. to facilitate evaluation of future malware detection approaches).

X-ware: a proof of concept malware utilizing artificial intelligenceIJECEIAES
Recent years have witnessed a dramatic growth in utilizing computational intelligence techniques for various domains. Coherently, malicious actors are expected to utilize these techniques against current security solutions. Despite the importance of these new potential threats, there remains a paucity of evidence on leveraging these research literature techniques. This article investigates the possibility of combining artificial neural networks and swarm intelligence to generate a new type of malware. We successfully created a proof of concept malware named X-ware, which we tested against the Windows-based systems. Developing this proof of concept may allow us to identify this potential threat’s characteristics for developing mitigation methods in the future. Furthermore, a method for recording the virus’s behavior and propagation throughout a file system is presented. The proposed virus prototype acts as a swarm system with a neural network-integrated for operations. The virus’s behavioral data is recorded and shown under a complex network format to describe the behavior and communication of the swarm. This paper has demonstrated that malware strengthened with computational intelligence is a credible threat. We envisage that our study can be utilized to assist current and future security researchers to help in implementing more effective countermeasures.
COMPARISON OF MALWARE CLASSIFICATION METHODS USING CONVOLUTIONAL NEURAL NETWO...IJNSA Journal
Malicious software is constantly being developed and improved, so detection and classification of malwareis an ever-evolving problem. Since traditional malware detection techniques fail to detect new/unknown malware, machine learning algorithms have been used to overcome this disadvantage. We present a Convolutional Neural Network (CNN) for malware type classification based on the API (Application Program Interface) calls. This research uses a database of 7107 instances of API call streams and 8 different malware types:Adware, Backdoor, Downloader, Dropper, Spyware, Trojan, Virus,Worm. We used a 1-Dimensional CNN by mapping API calls as categorical and term frequency-inverse document frequency (TF-IDF) vectors and compared the results to other classification techniques.The proposed 1-D CNN outperformed other classification techniques with 91% overall accuracy for both categorical and TF-IDF vectors.
Poly-meta-morphic malware looks different each time it is stored on di.docxrtodd884
Poly/meta-morphic malware looks different each time it is stored on disk or executed. Consider the challenges of detecting such malware.
Please respond to the following:
•   What is one approach to detect poly/meta-morphic malware? Your answer may address malware statically stored on disk or running in memory, and you may describe a publicly known solution or propose something novel.
•   What are the limitations of the method you described?
Solution
Malware is a one type of software which can harm the computer’s operating system and may also can steal the personal information from the computer, malware can be made by using any programming language by the programmer. It is very difficult to define a malware with a single term or a single name. A malware can be consider as a malicious software or malcode or as a malicious code .Malware do the bulk of the intrusive activities on a system and that spreads itself across the hosts in a network.
Malware is defined as software performing actions intended by an attacker, mostly with malicious intentions of stealing information, identity or other resources in the computing systems.There are different types of malware like adware, bots, Trojan horses, viruses, bugs, rootkits, spyware and worms. However, attributable to the technology advancement many malware writers try to use higher concealment techniques to avoid detection. The concealment technique is created with the combination of previous behaviour therefore on attack and at identical time to avoid the signature-based detection. In this, several common techniques that are commonly used like as polymorphic and metamorphic.
Stealth Malware
Malware creators’ initial tries therefore on turn tail from redounded to appear of stealing techniques. Stealth virus is prepared to cover its signs and traces. Virus normally changes and modifies info resources on the system. For example, a file-hosted virus would possibly append its own code to the tip of Associate in possible file. If Associate in application examines the infected file, it\'ll discover the being code inside the file and catch the virus.
clustering approach to identify and group harmful programs or apps samples that show almost the same behavior.almost the same behavior . This approach also energetic/changing analysis to get the execution traces of harmful programs or apps programs using automated tools.
This approach is used to boost the efficiency of dynamic malware analysis systems . It is a large sort of latest malicious files presently appears. It’s because of mutations of only variety of malware programs. The projected system avoids analyzing malware binaries that just represent mutated instances of already analyzed polymorphic malware. It drastically decrease the quantity of some time required for analyzing a set of malware programs.

A FRAMEWORK FOR ANALYSIS AND COMPARISON OF DYNAMIC MALWARE ANALYSIS TOOLSIJNSA Journal
Malware writers have employed various obfuscation and polymorphism techniques to thwart static analysis approaches and bypassing antivirus tools. Dynamic analysis techniques, however, have essentially overcome these deceits by observing the actual behaviour of the code execution. In this regard, various methods, techniques and tools have been proposed. However, because of the diverse concepts and strategies used in the implementation of these methods and tools, security researchers and malware analysts find it difficult to select the required optimum tool to investigate the behaviour of a malware and to contain the associated risk for their study. Focusing on two dynamic analysis techniques: Function Call monitoring and Information Flow Tracking, this paper presents a comparison framework for dynamic malware analysis tools. The framework will assist the researchers and analysts to recognize the tool’s implementation strategy, analysis approach, system-wide analysis support and its overall handling of binaries, helping them to select a suitable and effective one for their study and analysis.
A SURVEY ON MALWARE DETECTION AND ANALYSIS TOOLSIJNSA Journal
The huge amounts of data and information that need to be analyzed for possible malicious intent are one of the big and significant challenges that the Web faces today. Malicious software, also referred to as malware developed by attackers, is polymorphic and metamorphic in nature which can modify the code as it spreads. In addition, the diversity and volume of their variants severely undermine the effectiveness of traditional defenses that typically use signature-based techniques and are unable to detect malicious executables previously unknown. Malware family variants share typical patterns of behavior that indicate their origin and purpose. The behavioral trends observed either statically or dynamically can be manipulated by using machine learning techniques to identify and classify unknown malware into their established families. This survey paper gives an overview of the malware detection and analysis techniques and tools.

To improve network security different steps has been taken as size and importance of the network has
increases day by day. Then chances of a network attacks increases Network is mainly attacked by some
intrusions that are identified by network intrusion detection system. These intrusions are mainly present in data
packets and each packet has to scan for its detection. This paper works to develop a intrusion detection system
which utilizes the identity and signature of the intrusion for identifying different kinds of intrusions. As network
intrusion detection system need to be efficient enough that chance of false alarm generation should be less,
which means identifying as a intrusion but actually it is not an intrusion. Result obtained after analyzing this
system is quite good enough that nearly 90% of true alarms are generated. It detect intrusion for various

Malware Protection
Week5Part4-IS
Revision Fall2013
Malware Protection
Malware protection use to be known simply as virus protection. We have learned that
viruses are one form of malicious software and that a broader term to describe the
multitude of threats and the protection mechanism is needed. This is why the term
Malware is broader categorization of the threat and also the protection. Malware is a
portmanteau of the terms Malicious Software. Different malware protection packages
can cover a range of threats including viruses, worms, Trojans, spyware, adware, rootkits
to name a few.
As malware has evolved so has malware protection. Malware protection packages (MPP)
have evolved to provide more comprehensive protection mechanisms; including
firewalls, Intrusion Detection/Protection Systems (IDS/IPS), remote and central
management of system clusters, heterogeneous system protection and management,
signature and heuristic scanning, sandboxing to name just a few features.
It is important to understand that no one Malware Protection Package will find all pieces
of malware. Each package has its strengths and weaknesses. It is a good idea to always
have some form of malware protection running on your system in real time. However,
should you become infected it is useful to have an alternative strategy making use of
other scanners that you can run manually.
Free or Paid for Scanners
There is an adage that “you get what you pay for”. Generally this is true, but over time I
have found that there are some excellent free malware scanners that for single user
systems do a nice job. Some major requirements I have for a malware scanner are: it is
easy to run; does not require a lot of user interaction, uses little system resources, does a
good job finding and removing threats and automatically updates its signature database.
The following is not an endorsement for paid versus free scanners. It represents my
experiences for what they are worth.
I use to have a paid for Norton subscription. I found that over time the system footprint
for Norton grew which meant Norton required more CPU and overall system resources
for its real-time scanning processes. I think Norton has got better based on recent
experience I have with Windows 8 however at the time I had several performance
problems related to Norton. This got me to switch to free AVG. I used AVG for a while
and had real good luck, until AVG’s advertising got obnoxious. I decided to remove
AVG and found that process very difficult. I finally succeeded and then moved to using
free Avast. I have been using Avast for several years having very good luck.
I then started testing various malware scanners on virtual machines. This got me familiar
with Microsoft Security Essentials. This is a free product offered by Microsoft that nicely
integrates with Windows Vista and Windows 7 systems. I like the simplicity of its

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract :- Malware, short for malicious software, means a variety of forms of intrusive, hostile or annoying
program code or software. Malware is a pervasive problem in distributed computer and network systems.
Malware variants often have distinct byte level representations while in principal belong to the same family of
the malware. The byte level content is different because of small changes to the malware source code can result
in significantly different compiled object code. In this project we describe malware variants with the umbrella
term of polymorphism. We are the first to use the approach of structuring and decompilation to generate
malware signatures. We employ both dynamic and static analysis to classify the malware. Entropy analysis was
initially determines if the binary has undergone a code packing transformation. If a packed, dynamic analysis
employing application level emulation reveals the hidden code using entropy analysis to detect when unpacking
is complete. Static analysis is then identifies characteristics, the building signatures for control flow of graphs
in each procedure. Then the similarities between the set of control flow graphs and those are in a malware
database accumulate to establish a measure of similarity. A similarity search is performed on the malware
database to find similar objects to the query. Additionally, a more effective approximate flow graph matching
algorithm is proposed that uses the decompilation technique of structuring to generate string based signatures
amenable to the string edit distance. We use real and synthetic malware to demonstrate the effectiveness and
efficiency of Malwise.
Keywords: Bayes classifier, Computer Security, Random forest, Spyware.
I. Introduction
We are Discus about the packed and polymorphic malware, we proposes a novel system, named
malwise, for malware classification using a fast application level emulator to reverse the code packing
transformation, and two flow graph matching algorithms to perform classification. Now Present years, Internet
worms have proliferated because of hardware and software mono-cultures, which make it possible to exploit a
single vulnerability to compromise a large number of hosts. Most Internet worms follow a
scan/compromise/replicate pattern of behaviour, where the worm instance first identifies possible victims, then
exploits one or more vulnerabilities to compromise a host, and finally replicates there. These actions are
performed through network connections and, therefore, network intrusion detection systems (NIDSs) have been
proposed by the security community as mechanisms for detecting and responding to worm activity, the need for
the timely generation of worm detection signatures motivated the development of systems that analyze the
contents of network streams to automatically derive worm signatures. Cyber criminals constantly develop new
versions of their malicious software to evade pattern-based detection by anti-virus products.
The Data security company receives it has to be determined whether the sample is Malicious or has
been encountered before, it possibly in a modified form. Analogous to the human immune system, the ability to
recognize commonalities among malware which belong to the same malware family would allow anti-virus
products to proactively detect both known samples, as well as future releases of the malware samples from the
family.
II. Related Work
We use several real vulnerabilities to create polymorphic worms; run our signature generation
algorithms on workloads consisting of samples of these worms; evaluate the quality (as measured in false
positives and false negatives) of the signatures produced by these algorithms; and evaluate the computational
cost of these signature generation algorithms. Now Present anti-virus software typically employee a variety of
methods to detect malware programs, such as signature-based scanning, heuristic-based detection, and
behavioural detection

2.1 Single Polymorphic worms:
Now consider the anatomy of Polymorphic worms. We refer to a network flow containing a particular
infection attempt as an instance or sample of a polymorphic worm. After briefly characterizing the types of
content found in a polymorphic worm, we observe that samples of the same worm often share some invariant
content due to the fact that they exploit the same vulnerability. We provide examples of real-world software
vulnerabilities that support this observation. We design the SRE signature type from regular expression.
It is believed that regular expression has significant advantages for intrusion detection in terms of
flexibility, accuracy, and efficiency. Regular expressions have been widely used in intrusion detection systems,
for example, in Snort and Bro. However, the full regular expression is too complex and its numerous syntax
rules are not needed for worm detection. Hence, we introduce the simplified regular expression as a way of
representing worm signatures
2.2 Smaller signature set:
Symantec's signature set is currently tens of megabytes, and growing exponentially. If every signature
were to cover many files that would significantly slow signature set growth. Hancock can do this and also
generate replacements for old signatures, reducing the signature set's size. Detecting malware variants improves
signature based detection methods. The size of signature databases is growing exponentially, and detecting
entire families of related malicious software can prevent the blowout in the number of stored malware
signatures.
Malwise is a system for detecting malware based on a using a different kind of signature. A more
powerful and robust signature. In Malwise, the structure of a program is used instead of traditional string
signatures that are used in Antivirus. Program structure doesn't change much when malware evolves or mutates.
Program structure can effectively fingerprint an entire family of malware and detect new family
members even if they haven't been seen before by the system.
2.3 False Positive Check Index:
Illustrates the effects of accuracy and thresholds on the false positive index, with four illustrative base
rates (the false positive index is the number of false positive test results for each true positive test result). It
shows that increasing test accuracy makes for more attractive tradeoffs in using the test. For example, it shows
that that for any base rate, if the threshold is set so as to correctly detect 50 percent of truly positive cases, or
major security risks, a diagnostic with A = 0.80 has a false-positive index of about three times that of a
diagnostic with A = 0.90; a diagnostic with A = 0.70 has an index of about six times that of a test with A = 0.90;
and a diagnostic with A = 0.60 has an index of about eight times that of a test with A = 0.90. These ratios vary
somewhat with the threshold selected, but they illustrate how much difference it would make if a high value of
A could be achieved for field polygraph testing. If the diagnosis of deception could reach a level of A = 0.90,
testing would produce much more attractive tradeoffs between false positives and false negatives than it has at
lower levels of A.
Nevertheless, if the proportion of major security risks in the population being screened is equal to or
less than 1 in 1,000, it is reasonable to expect even with optimistic assessments of polygraph test accuracy that
each spy or terrorist that might be correctly identified as deceptive would be accompanied by at least hundreds
of non deceptive examinees mislabeled as deceptive, from whom the spy or terrorist would be indistinguishable
by polygraph test result. The possibility that deceptive examinees may use countermeasures makes this tradeoff
even less attractive.

III. Methodology
3.1 Topology Creation:
In this module we are constructing the topology for transmitting data. Based on this topology we are
testing our data transmission and data access. For creating the topology here we are using server socket to
connect nodes.
3.2 Generating Signature Tree for Multiple Polymorphic Worms:
We can generate signatures of these attacks by extracting their invariant parts and any two signatures
can be compared in terms of specifics according to definitions can we also organize the generated signatures
into a tree so as to represent the familial resemblance of the byte sequences of these attacks. One obvious benefit
of the tree organization would be that the (signature) tree would reflect and illustrate logical relations between
these attacks and shed light on how worm variants evolve over time. For example, if the signature of a new
attack is a child node of a known worm’s signature in the signature tree, we immediately know that this new
attack should be a variant of the known worm.
IV. System Implementation
Our approach employs both dynamic and static analysis to classify malware. Entropy analysis initially
determines if the binary has undergone a code packing transformation. If packed, dynamic analysis employing
application level emulation reveals the hidden code using entropy analysis to detect when unpacking is
complete.
Fig 2: home Page
If not, then Static analysis then identifies characteristics, building signatures for control flow graphs in
each procedure. The similarities between the set of control flow graphs and those in a malware database
accumulate to establish a measure of similarity. A similarity search is performed on the malware database to
find similar objects to the query.

Two approaches are employed to generate and compare flow graph signatures. Two flow graph
matching methods are used to achieve the goal of either effectiveness or efficiency.
a) Exact Matching is an ordering of the nodes in the control flow graph is used to generate a string based
signature or graph invariant of the flow graph.
Fig 4: open spydata
b) Approximate Matching is the control flow graph is structured in this approach. Structuring is the process of
decompiling unstructured control flow into higher level, source code like constructs including structured
conditions and iteration.
4.1 Data Collection:
Our data set consists of 100 binaries out of which 90 are benign and 10 are spyware binaries. The benign
files were collected from Download.com, which certifies the files to be free from spyware. The spyware files
were downloaded from the links provided by SpywareGuide.com. This hosts information about different types
of spyware and other types of malicious software.
Fig 5: run command
4.2 Byte Sequence Generation:
We have opted to use byte sequences as data set features in our experiment. These byte sequences
represent fragments of machine code from an executable file. We use xxd, which is a UNIX-based utility for
generating hexadecimal dumps of the binary files. From these hexadecimal dumps we may then extract byte
sequences, in terms of n-grams of different sizes.
4.3 Dataset Generation:
Two ARFF databases based on frequency and common features were generated. All input attributes in
the data set are represented by Booleans. These ranges are represented by either 1 or 0.

4.4 Feature Extraction:
The output from the parsing is further subjected to feature extraction. We extract the features by using
following approaches, the Common Feature-based Extraction (CFBE) and Frequency-based Feature Extraction.
The occurrence of a feature and the frequency of a feature. Both methods are used to obtain Reduced Feature
Sets (RFSs) which are then used to generate the ARFF files.
Fig 7: test for naivebayes
4.5 Classification:
A Naive Bayes classifier is a probabilistic classifier based on Bayes theorem with independence
assumptions, i.e., the different features in the data set are assumed not to be dependent of each other. This of
course, is seldom true for real-life applications. Nevertheless, the algorithm has shown good performance for a
wide variety of complex problems. J48 is a decision tree-based learning algorithm. During classification, it
adopts a top-down approach and traverses a tree for classification of any instance. Moreover, Random Forest is
an ensemble learner. In this ensemble, a collection of decision trees are generated to obtain a model that may
give better predictions than a single decision tree.

V. Conclusion
The Malware can be classified according to similarity in its flow graphs. This analysis is made more
challenging by packed malware. In this paper we proposed different algorithms to unpack malware using
application level emulation.
We also proposed performing malware classification using either the edit distance between structured
control flow graphs, or the estimation of isomorphism between control flow graphs. We implemented and
evaluated these approaches in a fully functionally system, named Malwise. The automated unpacking was
demonstrated to work against a promising number of synthetic samples using known packing tools, with high
speed. To detect the completion of unpacking, we proposed and evaluated the use of entropy analysis. It was
shown that our system can effectively identify variants of malware in samples of real malware. It was also
shown that there is a high probability that new malware is a variant of existing malware. Finally, it was
demonstrated the efficiency of unpacking and malware classification warrants Malwise as suitable for potential
applications including desktop and Internet gateway and Antivirus systems.
