Guide to preventing phishing and other cyber attacks

It’s not just large online brands and organizations that are at risk from phishing and other cyber attacks. The majority of threats are opportunistic, with cybercriminals only too happy to exploit any online weaknesses, regardless of the targeted organization’s size, cybersecurity budget, or the sector that it operates in.

Speaking to CBS News’ 60 Minutes, Federal Reserve Chair Jerome Powell said “The world evolves. And the risks change as well. And I would say that the risk that we keep our eyes on the most now is cyber risk” (cbsnews.com). The online environment “has become a more popular target for illicit trade which poses a major challenge to an innovation-driven global economy” according to a report (europa.eu) carried out by the EUIPO (European Observatory on Infringements of Intellectual Property Rights) and the OECD (Organisation for Economic Co-operation and Development).

In this guide, we will focus on how to detect, disrupt, and ultimately neutralize online threats impersonating your brands. Phishing and other cyber attacks can damage your organization’s reputation, cause huge financial losses, disrupt operations and the provision of services, and also threaten the online safety of your customers and prospects.

We’ll also take a look at how the most common cyber attacks work, and examine how Netcraft’s anti-cybercrime platform is uniquely positioned to combat online threats with unparalleled speed and accuracy.


Cybercrime threats, at a glance

The majority of cybercriminals are motivated by financial gain, and will use a variety of attack methods, requiring only modest technical ability, to exploit your organization’s digital channels.

They might construct fake shops purporting to sell branded goods that drives traffic away from your legitimate site. Or register a domain name that is so similar to yours that customers believe they’re using your website, when it’s in fact controlled by a criminal.

Alternatively, they could establish phishing sites designed to steal payment and personal information from your existing (and potential) customers. Or they might create convincing social media profiles or ads to mislead customers or direct them to malicious websites.

This is just a small selection of the types of cyber attack that criminals will exploit. Below are descriptions of the most common attack types and techniques.


Phishing attacks

Phishing is a type of online scam where criminals impersonate legitimate organizations in an attempt to trick victims into sharing personal information, such as passwords or credit card numbers. These scams can be very convincing and use logos, colors, and website layouts that look identical to those used by the impersonated organization. Phishing attacks can lead to real personal losses for each victim, as well as reputational and financial risk for the organizations that are targeted.

Phishing attacks are often launched on a massive scale, as criminals can send millions of scam emails and SMS messages quickly, at virtually no cost. If a victim clicks on a link from within the scam message, they’ll be directed to a phishing website, designed to look like those operated by established organizations. From here, the criminals will attempt to lure visitors into disclosing private and sensitive information (which can be used for future cyber attacks), or may trick victims into transferring funds into an account they control.

Phishing attacks have evolved over the years, going far beyond the stereotype of criminals in a far-off place sending millions of misspelled emails in the hopes of tricking a naive user to submit their bank account details. Modern phishing emails can be very difficult to spot, even by experienced users, and are expertly designed to mimic official communications.


Fake shops

Claiming to offer highly discounted goods, fraudulent online stores (or fake shops) impersonate the websites of luxury brands and established retailers. These shops are often a front to capture payment details (and other sensitive information) that users submit at the checkout stage of the transaction. These details can then be used to create convincing phishing attacks (described above) or sold on to other cybercriminals. For most victims, goods are rarely delivered, and those that are will most likely be counterfeit.

Fake shops don’t just harm your existing customers; they also drive your prospects away from your legitimate online store, costing brands financially and in terms of reputational damage.

Deceptive domains

Online retailers and businesses across all sectors use websites and domains to sell services and develop their brand. Criminals will ‘spoof’ legitimate domains (website addresses) in order to make their cyber attacks appear more convincing. This includes a number of techniques to make the domain look authentic, such as substituting lookalike characters – such as “o” (letter O) and “0” (zero) – or ‘typosquatting’ (when criminals register a common misspelling of another organization’s domain as their own).

The fake website will often include duplicated logos, trademarks and products of the spoofed site to make the scam more convincing. Victims are reassured when they see familiar branding, and are less likely to suspect malicious activity.


Fake mobile apps

The popularity of apps, which are installed on millions of phones and tablets, has led to cybercriminals creating fake copies of official apps in order to impersonate legitimate organizations . The aim is, again, to obtain their customers’ personal information or financial details, which are often required in order to install the app. Criminals will take organizations’ official apps from the Google Play and the Apple store and redistribute copies on their third-party sites, giving them opportunity for the app to be hacked before it’s installed.

Social media impersonation

Cyber criminals will create fraudulent Facebook pages, as well as fake Twitter and Instagram accounts, created to mislead and confuse potential victims. They can include scam celebrity endorsements designed to trick victims into visiting fake shops and other malicious websites, or fake profiles of your key employees (known as ‘executive impersonation’) that appear on LinkedIn and other professional networking sites.

Sophisticated detection techniques

At the core of Netcraft’s detection capability are highly effective searches across internet-scale datasets derived from Netcraft’s decades of experience mapping the internet.

Searches cover a wide range of digital channels including typosquatting or lookalike domains, compromised websites, social media platforms, search engine ads, email and SMS. Processing over five million threat reports each day, Netcraft continuously monitors for occurrences of our customers’ brand names, logos and trademarks online.

Detected threats are analyzed using our automated threat intelligence platform and those targeting customers begin the disruption & takedown process.


Disrupting cyber attacks

Once a cyber attack—a phishing website, fake social media profile, or fraudulent email, for example—has been detected through Netcraft’s cybercrime detection or by your own team and validated with our threat intelligence process, Netcraft blocks access to the attack and begins the takedown process.

Once blocked, users of the Netcraft apps and extensions are immediately protected. Netcraft also licenses its feeds to browsers and antivirus companies along with internet infrastructure companies, protecting billions of internet users from potential exposure while Netcraft’s automated takedown services work to rapidly take the attack offline completely.

Rapid takedown of malicious content

To conduct a takedown, Netcraft gathers evidence of the cyber attack, and begins to identify the relevant parties providing resources to the attacker. In parallel, Netcraft automatically contacts hosting providers, domain registrars, webmasters and others via email, API, private contact, or otherwise.

A suspected attack can be analyzed, validated, and takedown notifications dispatched within minutes of discovery. This is thanks to Netcraft’s highly automated takedown process which uses rule-based matching (and other machine learning technologies) to gather the necessary evidence that providers require to take down the malicious content.

Our automated takedown process is designed to rapidly identify and block malicious or fraudulent websites and domains in order to restore a safe online environment for you and your customers.
