Phishing attacks are a major concern for individuals and businesses alike, with 1 in 4 people falling victim to a phishing scam. This can lead to financial loss, identity theft, and damage to your reputation.
To prevent phishing attacks, it's essential to be cautious when clicking on links or providing personal information online. Be wary of emails or messages that ask for sensitive information, as 80% of phishing attacks start with an email.
Using strong and unique passwords for all online accounts can also help protect you from phishing attacks. This is because 75% of people use the same password for multiple accounts, making it easier for hackers to gain access.
Regularly updating your operating system and browser can also help prevent phishing attacks, as outdated software can leave you vulnerable to cyber threats.

What Is a Phishing Attack?
A phishing attack is a type of cybercrime where scammers try to trick people into giving away sensitive information like passwords, credit card numbers, or social security numbers.
Phishers often pretend to be a trusted source, like a bank or a government agency, to gain your trust. They might send you an email or message that looks legitimate, but has a hidden link or attachment that installs malware on your device.
Phishing attacks can happen through various channels, including email, text messages, and even phone calls. According to the article, phishing attacks are a leading cause of data breaches, with 81% of organizations experiencing a breach due to phishing.
These attacks are often carried out by organized crime groups, who use the stolen information for financial gain. In some cases, the stolen data is sold on the dark web, where it can be used for identity theft or other malicious purposes.

How Phishing Affects Your Business
Phishing attacks can be devastating to your business. Any disruption to your business can be devastating, and clearing out a phishing attack takes time.
You could be the target of a phishing attack unknowingly, and it's not just about your business being affected - your website could also be the source of one without realizing it. Scammers often hijack someone else's resources to send spam emails.
If your website is sending spam emails, your email accounts could be flagged for abuse and suspended, and so could your website. This could lead to your business coming to a sudden halt.

How an Attack Affects My Business
A phishing attack can have a significant impact on your business, and it's not just about the initial attack itself. Your business could be the source of a phishing attack without you even realizing it.
Scammers often hijack someone else's resources to send spam emails, which can lead to your email accounts being flagged for abuse and suspended. This can happen quickly, leaving your business in a difficult situation.
Any disruption to your business can be devastating, especially if you're a small business. In one case, a multinational firm instructed all 130,000 employees to disconnect from their laptops, causing a significant loss of productivity.
Clearing out a phishing attack takes time, and while you wait around, your business could suffer. This could be for days, weeks, or even longer, depending on the severity of the attack.
Your website could be blacklisted and your business could come to a sudden halt. This can be a nightmare to deal with, especially if you're not prepared.
Phished Brands in the Wild
The top 50 brands most commonly targeted by phishing attacks are a sobering reminder of the scope of the problem. AT&T Inc. tops the list, with a sample phishing domain of att-rsshelp[.]com.
PayPal is the second most targeted brand, with attackers using domains like paypal-opladen[.]be to trick victims into submitting sensitive information. Microsoft, DHL, Meta, and the Internal Revenue Service are also among the top 10 most targeted brands.
A closer look at the data reveals that attackers often use misspellings and concatenation of services to create phished domains. For example, a phishing domain for Microsoft might be login[.]microsoftonline.ccisystems[.]us. This tactic is designed to trick victims into thinking they're visiting a legitimate website.
Here are the top 10 most targeted brands:
These brands are often targeted because they have a large customer base and are perceived as high-value targets by attackers.
Preventing Phishing Attacks
Being proactive with website security is essential to avoid falling victim to phishing schemes. Anti-phishing software and malware programs can help protect websites from these types of attacks.

Example Attempt
Phishing attacks can be sneaky, but there are some red flags to watch out for. A phishing email might look like it's from your bank, complete with a logo and a URL that looks legitimate.
The problem is, the email address might not be the real deal. If you hover over the URL, you might see a different email address or a fake website. That's a big warning sign.
Hackers are also using social media to gather information. They'll create fake login pages for popular platforms like Instagram and Facebook, and send them to you. Once they get into your profile, they can steal your personal data.
A legitimate bank would never ask you to click a link and enter your social security number or banking information. They'd ask you to visit their official website, securely enter your login credentials, and change your password. That's a much safer option.
In fact, a bank would likely reset your password for you, rather than asking you to click on a suspicious link. That's just common sense.

Cloudflare Security Features
Cloudflare offers a robust security solution to protect against phishing attacks. Cloudflare's Security Center includes new Brand and Phishing Protection tools that automatically identify and block "confusable" domains.
These domains often result from common misspellings, such as clodflare.com, or concatenation of services, like cloudflare-okta.com, which attackers use to trick victims into submitting private information.
Cloudflare Security Center: New Brand & Protection Tools
Cloudflare's Security Center is getting a boost with new Brand and Phishing Protection tools. These tools automatically identify and block "confusable" domains, which are often used by attackers to trick victims into submitting private information.
Common misspellings like clodflare.com and concatenation of services like cloudflare-okta.com are now protected. These tools provide an additional layer of protection against phishing attempts.
Cloudflare One customers can access the new Brand and Phishing Protection tools under the Cloudflare Security Center. They offer more controls, such as custom strings to monitor and a searchable list of historical domains.
The new domain brand matching and alerting feature is a key part of Cloudflare's brand protection. It detects hostnames created for phishing legitimate brands by monitoring DNS queries made to 1.1.1.1, Cloudflare's public DNS resolver.
Cloudflare's system uses "fuzzy" matching to compare strings and calculate a similarity score based on factors like phonetics and substring matching. This allows for real-time detection of matches with saved patterns.
In the future, an automated matching system will simplify the process of detecting matches for users.

Matching SSL/TLS Certificates
Cloudflare's security features include matching SSL/TLS certificates against domains. This means we can identify potential phishing sites by checking if their certificates match the domains they claim to represent.
By analyzing Certificate Transparency logs, we can identify potentially fraudulent certificates. These certificates are often created shortly after domain registration in an attempt to give phishing sites more legitimacy by supporting HTTPS.

Understanding Phishing Threats
Phishing attacks are a serious threat to individuals and businesses alike. In the first quarter of 2025, there were 1,003,924 phishing attacks observed, the largest number since late 2023.
Phishing attacks often involve fake websites that look identical to legitimate ones, but with slight misspellings or modifications. For example, attackers may register a domain like "clodflare.com" to trick users into submitting private information.
To identify a phishing website, take the following steps: check the URL for misspellings or unusual characters, look for a padlock icon in the address bar, and be cautious of links that ask for sensitive information.
Phishing attacks are becoming more sophisticated, with attackers using QR codes to lead consumers to phishing sites and malware. In the first quarter of 2025, there was a significant increase in attacks against online payment and financial sectors.
A specific type of phishing attack called spear phishing targets specific individuals and accounts, often with the goal of gaining information on a particular company. This can lead to bigger data breaches that can be more profitable for scammers.

Identify a Website
To identify a website, pay attention to its overall quality. A legitimate website will have sharp graphics, correct spelling and grammar, and a polished feel.
Simple spelling mistakes, broken English, or grammatical errors can be a red flag that you're on a phishing site.
A legitimate website will usually have a "contact us" section with details like a postal address, phone number, email address, and social media channels. If this section is missing, it may indicate a phishing site.
Low-resolution images or a lack of effort in design can also suggest a phishing site.

Domain Brand Matching and Alerting
Domain brand matching and alerting is a crucial aspect of protecting against phishing threats. Our system uses a technique called "fuzzy" matching to compare strings and calculate a similarity score based on factors like phonetics, distance, and substring matching.
To detect matches, we monitor the first use of a domain or subdomain by sifting through trillions of daily DNS queries made to 1.1.1.1, Cloudflare's public DNS resolver. This allows us to compile a list of hostnames in the wild for the first time and perform matching against our users' saved patterns in real-time.
Our users can create and save custom strings, which can be strings with edit distances, to enable our system to generate alerts whenever we detect a match with any of the domains in the list. This is especially useful for security teams tracking more complex patterns.
In the future, we plan to introduce an automated matching system that will simplify the process of detecting matches for our users. This will make it easier for security teams to stay on top of potential threats.
Here are some examples of how our domain brand matching and alerting system works:
Note that these are just a few examples of the top 50 brands that are commonly targeted by phishing attacks, as reported in our Brand Protection tools.
Combining Threat Intelligence with Zero Trust
Combining threat intelligence with Zero Trust is a game-changer in the fight against phishing threats. You can easily block confusable domains found by threat intelligence capabilities by creating Cloudflare Gateway or DNS policy rules.
This means that as soon as a malicious domain is detected, you can immediately stop users from resolving or browsing to it, thwarting attacks before they happen.
By integrating threat intelligence with Zero Trust, you can significantly reduce the risk of phishing attacks.
