All of us are familiar with the importance of social media in facilitating communication. e-mail is one of the safest social media platforms for online communications and information transfer over the internet. As of now, many people rely on email or communications provided by strangers. Because everyone may send emails or a message, spammers have a great opportunity to compose spam messages about our many hobbies and passions, interests, and concerns. Our internet speeds are severely slowed down by spam, which also collects personal information like our phone numbers from our contact list. There is a lot of work involved in identifying these fraudsters and also identifying spam content. Email spam refers to the practice of sending large numbers of messages via email. The recipient bears the bulk of the cost of spam, therefore it's practically free advertising. Spam email is a form of commercial advertising for hackers that is financially viable due of the low cost of sending email. Anti-spam filters have become increasingly important as the volume of unwanted bulk e-mail (also spamming) grows. We can define a message, if it is a spam or not using this proposed model. Machine learning algorithms can be discussed in detail, and our data sets will be used to test them all, with the goal of identifying the one that is most accurate and precise in its identification of email spam. Society of machine learning techniques for detecting unsolicited mass email and spam.

Malware damages computers and the threat is a serious problem. Malware can be detected by pattern matching method or dynamic heuristic method. However, it is difficult to detect all new malware subspecies perfectly by existing methods. In this paper, we propose a new method which automatically detects new malware subspecies by static analysis of execution files and machine learning. The method can distinguish malware from benignware and it can also classify malware subspecies into malware families. We combine static analysis of execution files with machine learning classifier and natural language processing by machine learning. Information of DLL Import, assembly code and hexdump are acquired by static analysis of execution files of malware and benignware to create feature vectors. Paragraph vectors of information by static analysis of execution files are created by machine learning of PV-DBOW model for natural language processing. Support vector machine and classifier of k-nearest neighbor algorithm are used in our method, and the classifier learns paragraph vectors of information by static analysis. Unknown execution files are classified into malware or benignware by pre-learned SVM. Moreover, malware subspecies are also classified into malware families by pre-learned k-nearest. We evaluate the accuracy of the classification by experiments. We think that new malware subspecies can be effectively detected by our method without existing methods for malware analysis such as generic method and dynamic heuristic method.
