Differentiate between a script-bot and a smart-bot Largest Online Education Community- December 5, 2022
We labeled this sample dataset (either malware or botnet), which became the baseline for the dynamic feature selection and was used to train our neural network model. Ultimately, our framework employs the same sample set for learning the behavioral properties of botnet applications. After executing these applications in a sandbox, we collected the features that are most relevant to a botnet activity. The execution time for feature selection was 2 minutes, and the resultant schema was stored in a CSV file for further analysis using a Python script.
All the experiments are performed in a powerful feature of Weka workbench  known as Weka Experimental . It has a GUI explorer built-in for experimenting machine learning algorithms on big datasets, and robust enough to produce a large number of experimental results needed for evaluation and comparison. Normally, the validation in machine learning classifiers is performed in two different ways to assess accurate performance measures for classifiers. One method is called K- fold cross validation  and the other is known as random sampling validation . Consequently, we determined that applications that belong to a specific botnet family demonstrate certain C&C communication patterns. Specifically, each malware application belonging to a particular family performs similar actions while executing remote commands[23,24], sharing information, and implementing request/response mechanisms.
It clearly shows that, 92% of botnet dataset established TCP connection, whereas only 33% malware do so. Moreover, the average connections established by each botnet and malware application are 10 and 2.5 respectively. In order to get insight into the HTTP traffic, we also observed the GET requests initiated by both datasets. It can be seen from the Figs 21 and 22 that 40% of the botnet applications use GET command for communication, however, 23% of the malware samples use this feature to communicate externally via HTTP. Fig 13 shows the comparison of the top 1746 botnet and malware applications with respect to DNS requests.
Bots are not robots and they don’t symbolize the end of marketing or sales as we know it. You might have noticed these terms and others like them increasingly pop across your screen. While they each represent technological advances, it’s important to know the meaning of each and how they differ to ensure you remain informed on how they can impact you.
As for as DNS response record is concern, 95% of the botnet applications receive (average of 2.7) DNS server replies, whereas only 48% malware samples receive (average 0.9) DNS response. Fig 14 shows the response generated by DNS server also known as DNS_TYPE_A_Requests. Similarly, the total number of unsuccessful DNS queries is presented in Fig 15. On the average, the DNS server’s responses for botnet applications are more than those for malware samples.
They’re very good at what they do, but they’re unable to mimic conversational type language and their capabilities are basic. SmartBot360 combines the best of both worlds, by allowing your organization to create and maintain simple or complex AI chatbots in a DIY fashion, and only request expert consultation when needed. Save time by collecting patient information prior to their appointment, or recommend services based on assessment replies and goals.
Smart robots have the capacity for not only manual labor but cognitive tasks. Erik Brynjolfsson and Andrew McAfee, authors of “The Second Machine Age,” maintain that technological advances have led global culture to an inflection point rivaling that brought about by the industiral revolution. When thinking about bots, however, it’s important to maintain perspective. They can serve a variety of purposes and what they ultimately accomplish is dependent on the humans that control them. Search engines like Google extensively use bots, often known as web crawlers, to analyze content and index the web. The use of a bot in their case allows sites to be catalogued much faster and more scalably than humans could accomplish alone.
This chatbot focuses on emotional intelligence and deep learning techniques as well as artificial intelligence. It can give recommended courses of action based on symptoms and even connect you to a real doctor. Will ask you about your symptoms, body, medical history, and more before using a clever algorithm to bring up the most and least likely diagnoses.
We have found that this is very common in healthcare, as patients are impatient and want to get straight to their required information. Being able to effectively respond to such off-script patient utterances is what differentiates AI chatbots from scripted chatbots. Smart robots can collaborate with humans, working along-side them and learning from their behavior.
They’re still capable of performing tasks, but they’re much more sophisticated and personalized than the former. They’re better able to understand contexts and use analytics to personalize responses based on user profiles and past behavior. Lastly, dynamic analysis itself requires a comprehensive set of execution traces in order to represent complete a program behavior. Although it is impractical to completely observe a complex program behavior, yet several software programs have been introduced to extend code coverage like Monkey Runner . However, it is still argued [84,85] to effectively provide full behavior coverage with existing options. Android applications can access internal storage and external storage from SD cards.
Moreover, a similar trend was observed for unsuccessful DNS queries generated by the botnet applications, i.e it is higher than malware applications. Figs 4–7 and show the accuracy rates (in percent), precision, recall, F-measure for Drebin dataset using 10-fold cross validation. Although all ML classifiers produced relatively good accuracy rates i.e higher than 90% however, simple logistic regression outperforms the other tested classifiers. It correctly classifies 99.49% of Drebin dataset using the selected features to distinguish botnet applications.
- During the specified running time we have collected the frequencies of feature vector called by those applications.
- The unique differentiator is that Maya gets continuously trained on failed questions and is able to answer such questions going forward, thus making it an intuitive technology.
- Machine learning and data mining are extensively used in anomaly detection especially in establishing generic and heuristic methods .
- Moreover, it offers cross-platform compatibility by sharing its C&C system with Windows bots.
AI is important in healthcare chatbots because whenever a patient has an emergency or asks something similar to an existing question, it can answer or direct them to the appropriate page with the next steps to take. Patients smartbots expect immediate replies to their requests nowadays with chatbots being used in so many non-healthcare businesses. A chatbot can either provide the answer through the chatbot or direct them to a page with an answer.
Finally, in the learning component the sample of a known botnet dataset are trained with the help of ANN model. In addition to that, class labeling for the large scale Drebin dataset is performed using a backpropagation model. Various machine learning classifiers are applied to determine the most suitable classification algorithm to draw a clear line between botnet and other types of malicious applications. On the other hand, our proposed framework SMARbot uses 4891 malware samples obtained from  and employs various machine learning algorithms for classification. Unlike the aforementioned approaches, SMARTbot uses dynamic analysis in order to detect botnet behavioral patterns in mobile applications.
