The emailmay look likeit has been sent from a bank, the InternalRevenue Service or an online financial servicesuch as PayPal, escrow or an online financialrewards system. The website that the victim is redirectedto appears in every way to be real. Upon enteringusernames, passwords or any other vital information, it isnot unlikely that the website appears to crash. This isbecause the phisher has what he needs and doesn’t wantthe victim to find out about the phony website.
The simplified flow of information in a phishingattack is:1. A deceptive message is sent from the phisher to the user.2. A user provides confidential information to a phishingserver (normally after some interaction with the server).3. The phisher obtain the confidential information from theserver.4.

Phishing had been widely used at least half a decade ago but it still remains as oneof the popular methods to scam internet users .Many of us might still be wonderingwhy there are so many victims out there even though we had been taught from timeto stay aware of a phishing scam. There are five reasons here why phishing is still apopular trick and below are the reasons.#1- it tricks the victim with fear:one of the most common method is to trick the victim by sendingthem an email and tell them that their internet banking account isbeing compromised and need to click on a link to resolve the issue.Once the user followed the link, the user will be redirected to someforged website that looks similar to the banking website whichrequires the user to input his/her username and password. Once thatform is sent, all the data will be transmitted to the attacker controlledserver.
#2-it tricks the victim with special interest: Some scammers use the scenario such as winning lottery or viewingadult material to create a temptation for the victim to click on a linkthat redirects to the phishing site.#3-it is not a rocket science technology:Phishing attacks involves creating a forged website and it might bedifficult to certain people. However if it is compare to hacking abanking server, creating website is not that complicated. Thereforemany novice or intermediate scammer will choose to use thephishing method over any other method in their hacking project.#4-it can be launched via many types of communication channel:phishing can happen not only by simply building a forged websiteand anticipate for the victim to come to you. It can also involvesending emails to lure them to the forged website.
Besides that, a phishing scam uses as well the manipulation of aURL and post it as a comment or forum to trick them to theforged website. Apart from using the computer knowledge to lure thevictim, phishing can also be done via phone calls. The conclusion isthis type of scam can be done via multiple channels and multipletechniques.#5-Compromising one account is not the end.After stealing one’s credentials is not the end, but it can be thebeginning. Why is it so? Internet users nowadays have manyonline accounts for instance Facebook , Twitter, and LinkedIn.In common, most users will use the same username andpassword for each of the account so that remembering them isnot an issue. Hence this can lead to the users’ credentials thathad been stolen can be used as well for other accounts by thescammers.
