This report depicts the negative impact of email phishing and its affect in business and industries. Not only large businesses but also it can eventually interrupt the content of the confidentiality. Phishing attack is referred to as a method that is used for tricking the users by unknowingly provide those personal and financial data or sending capital to the attackers . In order to prevent the digitized system from the phishing attack it is necessary for the system developer to adopt proper protection mechanism. In order to prevent these kinds of attack the users should avoid clicking in unknown electronic mail contents and Links.
This report demonstrates the common phishing attacks and its potential damages However after identifying this issues possible mitigation strategies are also needed to be identified and those are also elaborated in this report. It has been found that the most common form of phishing attack is a form of electronic message like email for providing links to what appears to be legitimate site but is a malicious site that is generally controlled by the external attackers. These paper measures the role of phishing attack its possible classification and counter measurements. Besides the details of phishing attack the possible mitigation strategies are also developed and demonstrated in this report details.
Theft is referred to as a very popular idea among the members who are having high level of criminal intension. Financial records and other important belongings can eventually be hijacked with the phishing attack. If proper security mechanisms are not adopted the, the data will be easily hacked through external assaults. From outside the phishing attack looks like not at all different from a normal official communication but though it looks similar but its negative impact is very high. The attacker’s uses fraud website but the looks like an official one at the same time the content of the messages are also not identified as a viral one from the outside. As soon as the attackers send the emails to that person whom he or she wishes to attack a spam message received by the receiver. However, from outside, none of the receiver will be able to identify that whether the message is a malicious one or not.

In order to steal bank details and personnel confidential information this particular type of attacks mechanism re used by the hackers. Once the message will be received and clicked by the receiver their personal message contents will be hijacked.
For stealing the confidentiality of the consumers this particular attack takes place in the retails online stores. There are many online shopping stores which are facing continuous this kind of cyber attacks.
According to phishing is a kind of social engineering where the attackers are also identified as a phisher. The phishers are attempts to fetch legitimate confidentiality f the users or the sensitive of credential information through mimicking the role of electronic communication. During the development of any online store or shopping centre besides adopting the security standards the developers should also consider necessary phishing attacks preventing mechanism. Based on the background and details of the business necessary security is required to be adopted by the developers. In this kind of attacks the attackers cannot directly get the password or security code but influence the users to get attacked by clicking on the links and spam message content.
In traditional stage of attacks the phishers used to copy the codes from the IOL websites and all crafted pages those look similar like the part of the AOL. Besides phishing attack there are some other attack mechanism are also there in terms of snooping, spoofing etc. The cyber criminals use all these attacks for hijacking the confidential info ration from the user’s server.
The phishing information flow is consists of five different components. If cyber criminals who wish to hack confidential information from the server allows all these components work combiningly to deliver the possible outcome. The five components of the information flow include: user or the victim of the attack, phisher or the attacker, the phisher collector, phisher or the casher and the financial institution. It can be said that a complete phishing attack defines there different roles for the phishers.
The first role is the role of a mailer. These attackers send large number of email content to that person or system which they wish to attack. They generally used the botnets for sending this emails. These are directed towards the users to fraud websites. Then comes the role of the collectors who asset up the websites those are widely hosted by the compromised machines. These machines again prompt the users for providing confidential information for achieving the actual payouts. However, it has been found that in most of the cases between these phishers monetary exchanges are offers.
On the other hand it can be said that, before delving into the phishing attack it is important to clarify what s not actually phishing. Scam and auction fraud are not referred to as a phishing of it do not found to be involved in obtaining the user’s confidential credentials. After surveying different latest banking details it has been found that, the banking details are hijacked by the attackers through phishing attack.
Three different types of phishing attacks are there such as clone phishing, spear phishing, phone phishing. Phishing attack has spear beyond the emails to involve the VOIP, SMS, messaging, social networking sites and also even multiplayer games. Some major categories of phishing attacks are mentioned below:
Clone phishing: In this kid of phishing attacks the attackers widely creates cloned emails before attacking to the target person’s credentials. The attackers do this by getting data in terms of content and recipients addresses from the emails those were delivered previously. Then the attackers send the similar message content just by replacing the original content with malicious links. The attacker also employs address spoofing to ensure that the emails appear to be forming the original email senders. The email is claimed to be a re send of the original or the updated version as a major trapping strategy.
Spear phishing: Spear phishing targets only specific groups of people. It can be said that, instead of the casting out of the thousand of the emails randomly this kind of attacks are took place over a large number of people who are working for a single organization. These kinds of attacks are referred to as high level attacks which took place are large organizations or businesses.
Phone phishing: These kinds of attacks are somewhere differs from the email attacks. In this sort of attacks the victims are asked for dialing a particular number and as soon as the attackers dial the numbers the data stored in the server get hijacked and misused by the hijackers. For traditional cases, phone equipments use to have dedicated lines thus voice over the internet protocol has become a very easy one to manipulate.
These kinds of attacks have become a very common one due to the excessive usage of the shared key. Domain key identified mails allows the business organizations to take the major responsibility for transmitting the information from the sender to the recipient. In order to resolve the issues of phishing attack certain mitigation strategies are also elaborated below.
Email phishing has become one of the most major concerns for the users, who are utilizing emails for communication purposes. It is an extremely dangerous and vulnerable cyber threat that has acquired the entire world of technology. This type of cyber threat is responsible for causing various damages to the confidentiality and integrity of sensitive information or data of the users. However, there are some of the most important mitigation strategies or methods for the proper eradication of this cyber threat. The most important and significant methods for mitigation of email phishing are given below:
Access Control: The first and the foremost method to mitigate the cyber threat of email phishing is controlling the overall access. If the access of the utilization of emails will be controlled properly, the chances of this type of threat are highly reduced or diminished. Emails are considered as the most private and confidential data. This type of data should not be shared with anyone and thus to maintain the confidentiality and integrity, access control is required. It helps to selectively restrict the overall access to any specific place or data by means of placing a firewall in between. The users, who try to access the confidential data or information without the permission of the authorized users, are known as unauthorized users and this type of permission is termed as authorization. Access control restricts the overall usability of the emails and thus this is the most effective way to mitigate the risk of email phishing.
Proper Training: Another important to stop the email phishing is proper training. If this type of discrepancy is observed within an organization, the users should be given proper training so that they do not share any personal details over the emails. When they would be cautious of this fact, they will not click on any other link provided by the unauthorized web sites or unknown email sender. This would eventually reduce the chances of email phishing to a great extent and the emails of the employees will be secured. The users should have the capability to verify or differentiate the authorized or the unauthorized electronic mails. For this purpose, significant training is required. All types of potential issues or damages are hence avoided easily. They should know that no organization would ask for any confidential or sensitive data or information from their users. When such an email comes into the inbox of the user; they should verify the fact, whether it is from an authorized user or not.
Checking Legitimacy of Emails: The third important way to mitigate the cyber threat of email phishing is to check the legitimacy of the electronic mails of the users. The users should take a closer look on the display name of the sender while clicking on the email for the purpose of reading it. This would help them in understanding whether the sender is legitimate or not. Moreover, the legitimacy of the electronic mails is also checked by this. All the organizations utilize a specific domain for the emails or URLs, so that the email, which is originating from a separate domain, is marked with red flag.
Checking for Mismatched URLs: The next important method to mitigate the cyber threat of email phishing is the proper checking of the mismatched or wrong URLs. When the embedded URL seems properly valid, it should be hovered for showing a separate web address. Moreover, the users must be avoiding clicking on various links within emails unless and until these emails are absolutely sure of the fact that the links are legitimate.
Checking of Proper Subject: Another significant method or way to mitigate the several cyber threat of email phishing is checking of the subject of the sent electronic mail. Most of the phishing mails do not comprise of any generic subject or greeting, hence, it should be verified that the electronic mail contains a proper greeting and relevant subject. If this type of subject is absent, the email should be avoided and even discarded. The discarding of emails should be done only if the sender is unknown to the receiver. Often, a known sender send emails with no subject. This type of emails should not be discarded by the receiver
Installation of Anti Phishing Software: Another important way to mitigate the email phishing is to install the anti phishing software within the system. If the system will not comprise of this type of software, there is always a high chance that such emails would be coming and no notification would be provided. However, if an anti phishing software is present or is installed within the system, the victim can easily mitigate this type of risk or threat and their emails would be safe and secured.
The above-mentioned methods are extremely useful for any user to mitigate the overall risk of email phishing.
Conclusion
Therefore, from the above discussion, it can be concluded that email phishing is the sole attempt for the purpose of obtaining any type of sensitive information from the electronic mails like credit card credentials, passwords, usernames and many more. This is mainly done for various malicious reasons by means of remaining disguised as one of the most trustworthy entities within electronic communication. The email phishing is subsequently carried out by the email spoofing or even instant messaging. The users are often directed in entering their personal information within any particular fake web site. The users cannot differentiate amongst the legal or the illegal administrators of the web site. The most significant victims of this type of cyber threat are banks, social web sites, IT administrators, auction sites and online payment processors. The phishing emails mainly comprise of various links of the web sites, which are responsible for distributing malware. It is one of the most important example of the social engineering technique that is utilized for deceiving the users and also exploiting the weaknesses within the recent security of web site. The above report has properly outlined the entire concept of email phishing with relevant details. There are various potential damages that are possible with email phishing. All of these potential damages of the email phishing are properly mentioned here. Moreover, the users could be in great danger as it compromises with the security and confidentiality of the users. Significant mitigation methods are also given here.
The important recommendations for the victims of email phishing are given below:
The first recommendation is to restrict the total access of the usernames and passwords of the email account. This would eventually restrict the access of the data and the unauthorized users cannot access the information.
The second significant recommendation for the victims of email phishing is to restrict the overall usability of physical systems. Due to the restriction of physical systems, the hackers or the attackers cannot access the email and hence the chances of this type of cyber threat are reduced.
The third recommendation is to deploy a continuous monitoring, detection as well as response for the emails. A verification link is one of them. The users could be able to track down the activities, if any unauthorized user accesses the emails or email accounts.
The next recommendation is to limit the execution. There are various application control solutions that are responsible for mitigating the risks of execution. This type of methodology should be incorporated within any system for ensuring that only the specific list of authorized binaries would be running on the various systems.
