Browshing a new way to phishing using malicious browser extension. European Union Agency For Cybersecurity. Retrieved 20 December Read. Archived from the original on January 19, Typically this requires either the sender or recipient to have been previously hacked for the malicious third party to obtain the legitimate email. Retrieved April 17,

For covert redirect, an attacker could use a real website instead by corrupting the site with a malicious login popup dialogue box. This makes covert redirect different from others.

For example, suppose a victim clicks a malicious phishing link beginning with Facebook. A popup window from Facebook will ask whether the victim would like to authorize the app.

If the victim chooses to authorize the app, a "token" will be sent to the attacker and the victim's personal sensitive information could be exposed.

These information may include the email address, birth date, contacts, and work history. Worse still, the attacker may possibly control and operate the user's account.

This could potentially further compromise the victim. This vulnerability was discovered by Wang Jing, a Mathematics Ph. Users can be encouraged to click on various kinds of unexpected content for a variety of technical and social reasons.

For example, a malicious attachment might masquerade as a benign linked Google Doc. Alternatively users might be outraged by a fake news story, click a link and become infected.

Not all phishing attacks require a fake website. Messages that claimed to be from a bank told users to dial a phone number regarding problems with their bank accounts.

Vishing voice phishing sometimes uses fake caller-ID data to give the appearance that calls come from a trusted organization.

A phishing technique was described in detail in a paper and presentation delivered to the International HP Users Group, Interex.

The term "phishing" is said to have been coined by the well known spammer and hacker in the mids, Khan C Smith. Phishing on AOL was closely associated with the warez community that exchanged unlicensed software and the black hat hacking scene that perpetrated credit card fraud and other online crimes.

AOL enforcement would detect words used in AOL chat rooms to suspend the accounts of individuals involved in counterfeiting software and trading stolen accounts.

Since the symbol looked like a fish, and due to the popularity of phreaking it was adapted as "Phishing". AOHell , released in early , was a program designed to hack AOL users by allowing the attacker to pose as an AOL staff member, and send an instant message to a potential victim, asking him to reveal his password.

Once the victim had revealed the password, the attacker could access and use the victim's account for fraudulent purposes.

Phishing became so prevalent on AOL that they added a line on all instant messages stating: "no one working at AOL will ask for your password or billing information".

In late , AOL crackers resorted to phishing for legitimate accounts after AOL brought in measures in late to prevent using fake, algorithmically generated credit card numbers to open accounts.

The shutting down of the warez scene on AOL caused most phishers to leave the service. Retrieved May 5, There are anti-phishing websites which publish exact messages that have been recently circulating the internet, such as FraudWatch International and Millersmiles.

Such sites often provide specific details about the particular messages. As recently as , the adoption of anti-phishing strategies by businesses needing to protect personal and financial information was low.

These techniques include steps that can be taken by individuals, as well as by organizations.

Phone, web site, and email phishing can now be reported to authorities, as described below. People can be trained to recognize phishing attempts, and to deal with them through a variety of approaches.

Such education can be effective, especially where training emphasises conceptual knowledge [] and provides direct feedback.

Many organisations run regular simulated phishing campaigns targeting their staff to measure the effectiveness of their training.

People can take steps to avoid phishing attempts by slightly modifying their browsing habits. Alternatively, the address that the individual knows is the company's genuine website can be typed into the address bar of the browser, rather than trusting any hyperlinks in the suspected phishing message.

Nearly all legitimate e-mail messages from companies to their customers contain an item of information that is not readily available to phishers.

Some companies, for example PayPal , always address their customers by their username in emails, so if an email addresses the recipient in a generic fashion " Dear PayPal customer " it is likely to be an attempt at phishing.

However it is unsafe to assume that the presence of personal information alone guarantees that a message is legitimate, [] and some studies have shown that the presence of personal information does not significantly affect the success rate of phishing attacks; [] which suggests that most people do not pay attention to such details.

Emails from banks and credit card companies often include partial account numbers. However, recent research [] has shown that the public do not typically distinguish between the first few digits and the last few digits of an account number—a significant problem since the first few digits are often the same for all clients of a financial institution.

The Anti-Phishing Working Group produces regular report on trends in phishing attacks. Google posted a video demonstrating how to identify and protect yourself from Phishing scams.

A wide range of technical approaches are available to prevent phishing attacks reaching users or to prevent them from successfully capturing sensitive information.

Specialized spam filters can reduce the number of phishing emails that reach their addressees' inboxes.

These filters use a number of techniques including machine learning [] and natural language processing approaches to classify phishing emails, [] [] and reject email with forged addresses.

Another popular approach to fighting phishing is to maintain a list of known phishing sites and to check websites against the list.

One such service is the Safe Browsing service. Opera 9. Some implementations of this approach send the visited URLs to a central service to be checked, which has raised concerns about privacy.

An approach introduced in mid involves switching to a special DNS service that filters out known phishing domains: this will work with any browser, [] and is similar in principle to using a hosts file to block web adverts.

To mitigate the problem of phishing sites impersonating a victim site by embedding its images such as logos , several site owners have altered the images to send a message to the visitor that a site may be fraudulent.

The image may be moved to a new filename and the original permanently replaced, or a server can detect that the image was not requested as part of normal browsing, and instead send a warning image.

The Bank of America website [] [] is one of several that asks users to select a personal image marketed as SiteKey and displays this user-selected image with any forms that request a password.

Users of the bank's online services are instructed to enter a password only when they see the image they selected.

However, several studies suggest that few users refrain from entering their passwords when images are absent.

A similar system, in which an automatically generated "Identity Cue" consisting of a colored word within a colored box is displayed to each website user, is in use at other financial institutions.

Security skins [] [] are a related technique that involves overlaying a user-selected image onto the login form as a visual cue that the form is legitimate.

Unlike the website-based image schemes, however, the image itself is shared only between the user and the browser, and not between the user and the website.

The scheme also relies on a mutual authentication protocol, which makes it less vulnerable to attacks that affect user-only authentication schemes.

Still another technique relies on a dynamic grid of images that is different for each login attempt. The user must identify the pictures that fit their pre-chosen categories such as dogs, cars and flowers.

Only after they have correctly identified the pictures that fit their categories are they allowed to enter their alphanumeric password to complete the login.

Unlike the static images used on the Bank of America website, a dynamic image-based authentication method creates a one-time passcode for the login, requires active participation from the user, and is very difficult for a phishing website to correctly replicate because it would need to display a different grid of randomly generated images that includes the user's secret categories.

Several companies offer banks and other organizations likely to suffer from phishing scams round-the-clock services to monitor, analyze and assist in shutting down phishing websites.

Solutions have also emerged using the mobile phone [] smartphone as a second channel for verification and authorization of banking transactions.

Organisations can implement two factor or multi-factor authentication MFA , which requires a user to use at least 2 factors when logging in.

For example, a user must both present a smart card and a password. This mitigates some risk, in the event of a successful phishing attack, the stolen password on its own cannot be reused to further breach the protected system.

However, there are several attack methods which can defeat many of the typical systems. Organizations that prioritize security over convenience can require users of its computers to use an email client that redacts URLs from email messages, thus making it impossible for the reader of the email to click on a link, or even copy a URL.

While this may result in an inconvenience, it does almost completely eliminate email phishing attacks. An article in Forbes in August argues that the reason phishing problems persist even after a decade of anti-phishing technologies being sold is that phishing is "a technological medium to exploit human weaknesses" and that technology cannot fully compensate for human weaknesses.

On January 26, , the U. Federal Trade Commission filed the first lawsuit against a suspected phisher. The defendant, a Californian teenager, allegedly created a webpage designed to look like the America Online website, and used it to steal credit card information.

Secret Service Operation Firewall, which targeted notorious "carder" websites. Companies have also joined the effort to crack down on phishing.

On March 31, , Microsoft filed federal lawsuits in the U. District Court for the Western District of Washington. The lawsuits accuse " John Doe " defendants of obtaining passwords and confidential information.

March also saw a partnership between Microsoft and the Australian government teaching law enforcement officials how to combat various cyber crimes, including phishing.

He was found guilty of sending thousands of emails to America Online users, while posing as AOL's billing department, which prompted customers to submit personal and credit card information.

Facing a possible years in prison for the CAN-SPAM violation and ten other counts including wire fraud , the unauthorized use of credit cards, and the misuse of AOL's trademark, he was sentenced to serve 70 months.

Goodin had been in custody since failing to appear for an earlier court hearing and began serving his prison term immediately. From Wikipedia, the free encyclopedia.

Whatever the real reason some birds respond to pishing, it is clear that this talkative technique can be an asset to birders who use it responsibly.

Studies and bird reports have shown that some birds are more responsive to pishing than others. In general, the technique is largely effective in North America and northern Europe but less effective in tropical habitats.

This may be because of the different bird sounds species make in different regions of the world and pishing is only useful in areas where birds naturally make similar sounds.

Whether or not birds respond to pishing also depends on environmental conditions, including ambient noise levels caused by weather, bird song, and nearby humans.

Individual birds may also vary in their responses depending on how frequently they hear pishing. Pishing is an easy technique to master and many birders have their sounds that work best in the field.

Different sounds can be effective, though most are made with the teeth together and repeated three to five times in a slow, regular tempo.

Changing the tempo or adding additional sounds to each pish sequence can also entice birds to respond.

Kissing or lip-smacking noises, tongue clicks, and a rapid "chit-chit-chit" noise are pishing alternatives that can also get the attention of curious birds.

The volume of the pish should be kept at or slightly softer than a conversational tone. Birds have excellent hearing and very loud pishes are likely to chase birds away rather than attract them.
