Fraud Alert: Phishing —

The Latest Tactics and Potential

Business Impact



As one of the top cyber crime ploys impacting both consumers and businesses, phishing has

grown in volume and sophistication over the past several years. The down economy is

providing a breeding ground for new, socially-engineered attempts to defraud unsuspecting

business people and consumers. With honest money-earning avenues less available, the

cyber crime ecosystem is ready with off-the-shelf phishing kits. It no longer takes a hacker

to enable and commit fraud on the Internet — anyone with a motive can join in.

The potential impact on a business can be great — whether an employee or its customers

have been phished, or the company Web site has been compromised. Organizations need

to stay current on the latest methods employed by cyber criminals and proactively take

steps to prevent this type of fraud.

This fraud alert highlights the current growth and trends in today’s phishing schemes,

the potential impact on companies, and insight into how businesses can apply

technology to protect themselves and their customers.


Phishing Knows No Limits

Phishing — luring unsuspecting users to provide sensitive information for identity or

business theft — is a serious threat for both consumers and businesses. In the last decade

since phishing arrived on the scene, this fraud method has been growing rapidly, with

one estimate citing approximately 8 million daily phishing attempts worldwide.1

The Anti-Phishing Working Group (APWG) reported that unique phishing attacks

submitted to APWG rose 13 percent during the second quarter of 2008 to more than

28,000.2 It also reported that, during the same period, the number of malware-spreading

URLs infecting PCs with password-stealing code rose to a new record of more than 9,500

sites — a 258% increase compared with the same quarter in 2007. Figure 1 shows one

area of phishing — spear phishing — and its growth over a 16-month period.


Be Aware of the Latest Phishing Schemes


Spear Phishing

Targeted versions of phishing, called spear phishing, have emerged over the past several

years. While common phishing is indiscriminate in its targets, spear phishing targets are

known customers of a specific bank, mortgage provider, or other type of organization.

Consumers aren’t the only targets of spear phishing. Increasingly, corporate employees are

being targeted by savvy criminals. In these attacks, the goal is to gain access to corporate

banking information, customer databases, and other information to facilitate cyber crime.

According to VeriSign iDefense, spear phishing against corporations reached new heights

during April and May 2008. Many of these attacks target senior executives and other

high-profile individuals. The victim counts from these attacks is staggering — over

15,000 corporate users in 15 months. Victims include Fortune 500 companies,

government agencies, financial institutions and legal firms.


Business Services Phishing

In addition to spear phishing targeted at employees, there have been recent schemes

targeting businesses using services such as Yahoo! or Google AdWords. PhishTank

reported that AdWords customers were sent e-mails alerting them that their accounts

required updating. The account holder was encouraged to log into the spoofed AdWords

interface and then provide credit card information.4 With many small and mid-size

companies relying on online advertising to drive traffic to their sites, their marketing

managers could be easy prey for this type of phishing scam.

Phishing that Plays on Economic Fears

Today’s economic turmoil delivers unprecedented opportunities for criminals to exploit

victims. For instance, popular scams include phishing e-mails that look like they are

coming from a financial institution that recently acquired the target victim’s bank, savings

& loan, or mortgage holder.5 The large amount of merger and acquisition activity taking

place creates an atmosphere of confusion for consumers, exacerbated by the dearth of

consistent communications with customers. Phishers thrive in this type of situation.


Blended Phishing/Malware Threats

To increase success rates, some attacks combine phishing with malware for a blended

attack model. For instance, a potential victim receives a phishing e-card via e-mail that

appears to be legitimate. By clicking on the link inside the e-mail to receive the card, the

person is taken to a spoofed Web site which downloads a Trojan to the victim’s computer.

Alternatively, the victim may see a message that indicates a download of updated software

is needed before the victim can view the card. When the victim downloads the software,

it’s actually a keylogger.

5. “FTC Consumer Alert: Bank Failures, Mergers and Takeovers: A Phish-erman’s Special,”


Phishing-based keyloggers have tracking components which attempt to monitor specific

actions (and specific organizations such as financial institutions, online retailers, and ecommerce

merchants) in order to obtain sensitive information such as account numbers,

userids, and passwords.

Another type of Trojan that enables phishers to capture sensitive information is a

redirector. Redirectors route end users’ network traffic to a location where it was not

intended to go. The APWG is seeing significant increases in both phishing-based

keyloggers and redirectors.6

Man-in-the-Middle SSL Stripping

During 2008, a new type of malware was introduced that allows cyber criminals to spoof

an encrypted session. This is a variance on the standard man-in-the-middle (MITM)

attack that criminals use to access passwords or sensitive information passing unprotected

over the network.


Texting and Mobile Phone Phishing Scams

Posing as a real financial institution, phishers are using SMS as an alternative to e-mail

to attempt to gain access to confidential account information. Known as “smishing”, the

typical scam informs the mobile phone user that the person’s bank account has been

compromised or credit card/ATM card has been deactivated. The potential victim is

directed to call a number or go to a spoofed Web site to reactivate the card. Once on the

site, or through an automated phone system, the potential victim is asked for card and

account numbers and PIN numbers.


How Phishing Could Impact Your Business

While the financial industry continues to be a primary target for phishers, it’s certainly

not the only sector vulnerable to attack. Auction sites, payment services, retail, and social

networking sites are also frequent targets. The APWG also reports a massive increase in

attacks aimed at cell phone providers and manufacturers. In short, no business or brand

is inherently safe.

Phishing attacks that pose as a company’s official Web site diminish the company’s

online brand and deter customers from using the actual Web site out of fear of

becoming a fraud victim. In addition to the direct costs of fraud losses, businesses whose

customers fall victim to a phishing scam also risk:

• A drop in online revenues and/or usage due to decreased customer trust

• Potential non-compliance fines if customer data is compromised

Even phishing scams aimed at other brands can impact a business. The resulting fear

caused by phishing can cause consumers to stop transacting with anyone they can’t trust.


Protecting Your Business

While there is no silver bullet, there are technologies that can help protect you and your

customers. Many of the current phishing techniques rely on driving customers to

spoofed Web sites to capture personal information. Technology such as Secure Sockets

Layer (SSL) and Extended Validation (EV) SSL are critical in fighting phishing and other

forms of cyber crime by encrypting sensitive information and helping customers

authenticate your site.

Security best practices call for implementing the highest levels of encryption and

authentication possible to protect against cyber fraud and build customer trust in the

brand. SSL, the world standard for Web security, is the technology used to encrypt and

protect information transmitted over the Web with the ubiquitous HTTPS protocol. SSL

protects data in motion which can be intercepted and tampered with if sent

unencrypted. Support for SSL is built into all major operating systems, Web browsers,

Internet applications, and server hardware.

To help prevent phishing attacks from being successful and to build customer trust,

companies also need a way to show customers that they are a legitimate business.

Extended Validation (EV) SSL Certificates are the answer, offering the highest level of

authentication available with an SSL Certificate and providing tangible proof to online

users that the site is indeed a legitimate business.

EV SSL gives Web site visitors an easy and reliable way to establish trust online by

triggering high security Web browsers to display a green address bar with the name of the

organization that owns the SSL Certificate and the name of the Certificate Authority

that issued it. Figure 2 shows the green address bar in Internet Explorer.

The green bar shows site visitors that the transaction is encrypted and the organization

has been authenticated according to the most rigorous industry standard. Phishers can

then no longer capitalize on visitors not noticing they are not on a true SSL session.

EV SSL Certificate


While cyber criminals are becoming adept at mimicking legitimate Web sites, without

the company’s EV SSL Certificate there is no way they can display its name on the

address bar because the information shown there is outside of their control. And they

cannot obtain the legitimate company’s EV SSL Certificates because of the stringent

authentication process.


Consumer and Employee Education

In addition to implementing EV SSL technology, businesses should continue to educate

their customers and employees on safe Internet practices and how to avoid cyber fraud.

Teach them how to recognize the signs of a phishing attempt such as: misspellings (less

common as phishers become more sophisticated), generic greetings instead of being

personalized, urgent calls-to-action, account status threats, requests for personal

information, and fake domain names/links.

Also educate your customers and employees on how to recognize a valid, secure Web site

before they provide any personal or sensitive information by:

• Looking for the green bar

•Making sure the URL is HTTPS

• Clicking on the padlock to match the certificate information with the Web site they

intended to go to

Education is a key component of building the trust necessary to overcome phishing fears.

By helping your customers understand how to confirm they are safe on your Web site,

you can grow revenues, differentiate your offering, and/or benefit from operational

savings by moving more transactions online.



Phishing will continue to evolve into new forms, while attempting to take advantage of

human behaviors such as compassion, trust, or curiosity. Protecting your brand and your

business from phishing requires constant diligence, but pays rewards beyond reduced

fraud losses.

By educating and protecting your customers with the highest levels of protection

provided by EV SSL Certificates, your business can ensure customers have greater

confidence in your online services. By demonstrating leadership in online security, you

can broaden your market appeal and in doing so, generate new revenue streams.



Certificate Authority (CA)— A Certificate Authority is a trusted third-party

organization that issues digital certificates such as Secure Sockets Layer (SSL) Certificates

after verifying the information included in the Certificates.

Encryption— Encryption is the process of scrambling a message so that only the

intended audience has access to the information. Secure Sockets Layer (SSL) technology

establishes a private communication channel where data can be encrypted during online

transmission, protecting sensitive information from electronic eavesdropping.

Extended Validation (EV) SSL Certificate— Requires a high standard for verification of

Secure Sockets (SSL) Certificates dictated by a third party, the CA/Browser Forum. In

Microsoft® Internet Explorer 7 and other popular high security browsers, Web sites secured

with Extended Validation SSL Certificates cause the URL address bar to turn green.

HTTPS— Web pages beginning with "https" instead of "http" enable secure

information transmission via the protocol for secure http. “Https” is one measure of

security to look for when sending or sharing confidential information such as credit card

numbers, private data records, or business partner data.


Secure Sockets Layer (SSL) Technology— SSL and its successor, transport layer security

(TLS), use cryptography to provide security for online transactions. SSL uses two keys to

encrypt and decrypt data − a public key known to everyone and a private or secret key

known only to the recipient of the message.

SSL Certificate— A Secure Sockets Layer (SSL) Certificate incorporates a digital

signature to bind together a public key with an identity. SSL Certificates enable

encryption of sensitive information during online transactions, and in the case of

organizationally validated Certificates, also serve as an attestation of the Certificate

owner’s identity.
