This information can then be used to craft a believable email. Typically, a victim receives a message that appears to have been sent by a known contact or organization.

The attack is then carried out either through a malicious file attachment, or through links connecting to malicious websites.

Although many phishing emails are poorly written and clearly fake, cybercriminal groups increasingly use the same techniques professional marketers use to identify the most effective types of messages.

Successful phishing messages are difficult to distinguish from real messages. Usually, they are represented as being from a well-known company, even including corporate logos and other collected identifying data.

These include:. Cybercriminals continue to hone their skills in making existing phishing attacks and creating new types of phishing scams.

Some common types of phishing attacks include:. Spear phishing attacks , which are directed at specific individuals or companies.

These attacks usually employ gathered information specific to the victim to more successfully represent the message as being authentic. Spear phishing emails might include references to co-workers or executives at the victim's organization, as well as the use of the victim's name, location or other personal information.

This attack often carries the objective of stealing large sums. Those preparing a spear phishing campaign research their victims in detail to create a more genuine message.

Using information relevant or specific to a target increases the chances of the attack being successful. Because, a typical whaling attack targets an employee with the ability to authorize payments, the phishing message often appears to be a command from an executive to authorize a large payment to a vendor when, in fact, the payment would be made to the attackers.

This is done in an attempt to trick users into attempting to log in to the fake site with personal credentials. Clone phishing attacks use previously delivered but legitimate emails that contain either a link or an attachment.

Attackers make a copy -- or clone -- of the legitimate email, and replace any number of links or attached files with malicious ones.

Victims can often be tricked into clicking the malicious link or opening the malicious attachment. This technique is often used by attackers who have taken control of another victim's system.

In this case, the attackers use their control of one system within an organization to email messages from a trusted sender, known to the victims.

Normally something similar to a real-sounding access point. When victims connect to the evil twin network, the attackers gain access to all transmissions to or from victim devices.

This includes access to user IDs and passwords. Attackers can also use this vector to target victim devices with their own fraudulent prompts.

A typical scam of this type uses speech synthesis software to leave voicemails notifying the victim of suspicious activity in a bank or credit account.

The call will solicit the victim to respond to verify their identity -- thus compromising the victim's account credentials.

Phishing attacks depend on more than simply sending an email to victims and hoping that they click on a malicious link or open a malicious attachment.

Attackers use several techniques to entrap their victims:. To help prevent phishing messages from reaching end users, experts recommend layering security controls, including:.

This can, include the DomainKeys Identified Mail DKIM protocol, which enables users to block all messages except for those that have been cryptographically signed.

DMARC provides a framework for using protocols to block unsolicited emails more effectively. There are several resources on the internet that provide help to combat phishing.

Interactive security awareness training aids, such as Wombat Security Technologies' PhishMe, can help teach employees how to avoid phishing traps.

In addition, sites like FraudWatch International and MillerSmiles publish the latest phishing email subject lines that are circulating the internet.

Phishing scams come in all shapes and sizes. Users can stay safe, alert and prepared by knowing about some of the more recent ways that scammers have been phishing.

A few examples of more modern phishing attacks include:. These happen when major payment applications and websites are used as a ruse to gain sensitive information from phishing victims.

In this scam, a phisher masquerades as an online payment service such as PayPal, Venmo or TransferWise. Generally, these attacks are performed through email, where a fake version of a trusted payment service asks a user to verify log in details and other identifying information.

Usually, they claim that this is necessary in order to resolve an issue with the user's account. Often, these phishing attempts include a link to a fraudulent "spoof" page.

PayPal is aware of these threats and has released informational materials for their customers to reference in order to stay prepared against phishing attacks.

They recommend that anyone who receives a suspicious email from an account claiming to be PayPal should not click any links, but instead, use the hovering technique outlined above to see if the link address matches PayPal's actual domain.

PayPal also advised to then separately log in to their account to make sure everything looks like it should. If a user is unsure of how to spot a fraudulent online-payment phishing email, there are a few details to look out for.

Generally, a phishing email from PayPal has been known to include:. If a person receives one of these emails, they should open their payment page on a separate browser tab or window and see if their account has any alerts.

If a user has been overpaid or is facing suspension, it will say so there. Additionally, PayPal urges users to report any suspicious activity to them, so they can continue to monitor these attempts and prevent their users from getting scammed.

These are common forms of phishing, and it operates on the assumption that victims will panic into giving the scammer personal information. Usually, in these cases, the scammer poses as a bank or other financial institution.

In an email or phone call, the scammer informs their potential victim that their security has been compromised.

Often, scammers will use the threat of identity theft to successfully do just that. These are especially alarming, as this type of scam can be very personalized and hard to spot.

In these cases, an attacker purporting to be the recipient's boss, CEO or CFO contacts the victim, and requests a wire transfer or a fake purchase.

One work-related scam that has been popping up around businesses in the last couple of years is a ploy to harvest passwords.

This scam often targets executive-level employees, since they are likely not considering that an email from their boss could be a scam.

The fraudulent email often works because, instead of being alarmist, it simply talks about regular workplace subjects. Usually, it informs the victim that a scheduled meeting needs to be changed.

From there, the employee is asked to fill out a poll about when a good time to reschedule would be via a link. That link will then bring the victim to a spoof login page for Office or Microsoft Outlook.

Once they have entered your login information, the scammers steal their password. One common explanation for the term is that phishing is a homophone of fishing.

And it is named so because phishing scams use lures to catch unsuspecting victims, or fish. Those characters were a common HTML tag found in chat transcripts.

Because it occurred so frequently in those logs, AOL admins could not productively search for it as a marker of potentially improper activity.

All of which could have eventually given the activity its name, since the characters appear to be a simple rendering of a fish.

In the early s, a group of individuals called the Warez Group created an algorithm that would generate credit card numbers. The numbers were created at random in the attempt to create fake AOL accounts.

The faked account would then spam other AOL accounts. Using these screen names, they would then "phish" people via AOL Messenger for their information.

In the early s, phishing saw more changes in implementation. The "love bug of " is an example of this. Also, in the early s, different phishers began to register phishing websites.

A phishing website is a domain similar in name and appearance to an official website. Today, phishing schemes have gotten more varied, and are potentially more dangerous than before.

More modern technologies are also being utilized now. As an example, the CEO of an energy firm in the U. It is unclear whether the attackers used bots to react to the victim's questions.

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.

Remember that if it seems to good to be true, it probably is! Some of them will even tell you that you have only a few minutes to respond. Sometimes, they will tell you that your account will be suspended unless you update your personal details immediately.

Most reliable organizations give ample time before they terminate an account and they never ask patrons to update personal details over the Internet.

In phishing, typically a fraudulent e-mail message is used to direct a potential victim to a World Wide Web site that mimics the appearance of a familiar bank or e-commerce site.

In addition to or instead of directly defrauding a victim, this information may be used by criminals to perpetrate identity theft , which may not be discovered for many years.

The e-mails appear to come from trusted or known sources. The American computer security company Symantec estimated that in more than 95 billion phishing e-mails were sent out globally.

According to the global Anti-Phishing Working Group, there were tens of thousands of phishing Web sites. Info Print Cite.

Submit Feedback. Phishing is an example of social engineering techniques used to deceive users. Attempts to deal with phishing incidents include legislation , user training, public awareness, and technical security measures the latter being due to phishing attacks frequently exploiting weaknesses in current web security.

The word is a neologism created as a homophone of fishing. Phishing attempts directed at specific individuals or companies is known as spear phishing.

Within organizations, spear phishing targets employees, typically executives or those that work in financial departments that have access to financial data.

Threat Group Fancy Bear used spear phishing tactics to target email accounts linked to Hillary Clinton 's presidential campaign.

They attacked more than 1, Google accounts and implemented the accounts-google. The term whaling refers to spear phishing attacks directed specifically at senior executives and other high-profile targets.

The content of a whaling attack email may be an executive issue such as a subpoena or customer complaint. This usually begins online, with the hope or promise of it progressing to real-life romance.

This is never the object of the perpetrator; in general, he is seeking access to the mark's money or resources, or to receive gifts or other consideration from the victim.

Occasionally, it may be a form of self-serving attention-getting. Clone phishing is a type of phishing attack whereby a legitimate, and previously delivered, email containing an attachment or link has had its content and recipient address es taken and used to create an almost identical or cloned email.

The attachment or link within the email is replaced with a malicious version and then sent from an email address spoofed to appear to come from the original sender.

It may claim to be a resend of the original or an updated version to the original. Typically this requires either the sender or recipient to have been previously hacked for the malicious third party to obtain the legitimate email.

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.

SMS phishing [23] or smishing [24] uses cell phone text messages to deliver the bait to induce people to divulge their personal information.

The victim is then invited to provide their private data; often, credentials to other websites or services.

Furthermore, due to the nature of mobile browsers, URLs may not be fully displayed; this may make it more difficult to identify an illegitimate logon page.

Smishing messages may come from telephone numbers that are in a strange or unexpected format. Most types of phishing use some form of technical deception designed to make a link in an email and the spoofed website it leads to appear to belong to the spoofed organization.

Many desktop email clients and web browsers will show a link's target URL in the status bar while hovering the mouse over it. This behavior, however, may in some circumstances be overridden by the phisher.

Internationalized domain names IDN can be exploited via IDN spoofing [34] or homograph attacks , [35] to create web addresses visually identical to a legitimate site, that lead instead to malicious version.

Phishers have taken advantage of a similar risk, using open URL redirectors on the websites of trusted organizations to disguise malicious URLs with a trusted domain.

Phishers have sometimes used images instead of text to make it harder for anti-phishing filters to detect the text commonly used in phishing emails.

To avoid anti-phishing techniques that scan websites for phishing-related text, phishers sometimes use Adobe Flash a technique known as phlashing.

These look much like the real website, but hide the text in a multimedia object. Some phishing scams use JavaScript commands in order to alter the address bar of the website they lead to.

An attacker can also potentially use flaws in a trusted website's own scripts against the victim.

In reality, the link to the website is crafted to carry out the attack, making it very difficult to spot without specialist knowledge.

Such a flaw was used in against PayPal. Covert redirect is a subtle method to perform phishing attacks that makes links appear legitimate, but actually redirect a victim to an attacker's website.

The flaw is usually masqueraded under a log-in popup based on an affected site's domain. This often makes use of open redirect and XSS vulnerabilities in the third-party application websites.

Normal phishing attempts can be easy to spot because the malicious page's URL will usually be different from the real site link.

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.

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 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.
