What is phishing and how does it work?

No one is safe from a phishing attack.

Phishing is a type of social engineering attack where someone tries to trick the user into revealing information. This is most often done via malicious websites and emails.

Email phishing happens when an email from a sender appears to come from someone you know, but it's actually from a malicious actor. It could be an email from your bank, for example, but what you don't know is that the email actually came from a fake email account and not your bank. The goal of the phisher is to trick you into giving up your login credentials—or any other sensitive information—by clicking on links or downloading attachments that contain malware.

Phishers who send out spear phishing emails go a step further and target specific individuals or businesses instead of sending out mass emails indiscriminately. The goal is usually to steal data from those individuals or businesses. The hackers might trick someone into wiring money to them, or they might create a fake form to capture credit card or banking info. The possibilities are endless, but the main goal in all of this is deception.

There are over 18,000 phishing domains registered daily

20% of all employees in an organization will likely click a link in a phishing email

In the last 6 years, the average cost of a phishing attack has quadrupled and is currently $14.8 million

Phishing attacks are everywhere

Phishing is one of the most common tactics used by hackers to gain access to data. Large organizations are often targeted with spear phishing campaigns that are personalized for the company’s security team.

Spear phishing campaigns are harder to detect because they require more time, effort, and resources on behalf of the sender. Hackers are clever in their spear phishing emails, fake ads, or social campaigns. They learn things about your role or you as an individual, and use that as a way to gain your trust and pull off their scheme.

Small businesses are also at risk of spear phishing attacks. Common targets include small business owners or managers who have access to company bank accounts or W-2 information. These small companies may not have any cybersecurity measures in place which makes them easy targets for hackers looking for sensitive information without raising suspicion.

Phishing attacks have moved from targeting individuals to going after organizations. While large companies with resources are a lucrative target, 1 in 4 data breaches in the US in 2020 involved a small company. Every organization, no matter the size, is at risk.

How can you stop phishing?

New domains are the biggest threats when it comes to phishing attacks. These attacks are often assembled quickly from kits, meaning it’s easy for hackers to get new sites up as their old ones are taken down. Old methods, like a list of threat feeds, isn't enough to combat phishing.

With DNS Security, phishing attacks can be prevented by filtering out malicious websites that have never even been senen before.

Every new link you encounter in the course of the day has the possibility of being a phishing website or other malicious site—especially sites that have only been registered in the last 30 days. You can protect your company and your employees by implementing AI-driven PDNS and blocking new and uncategorized domains, in addition to known phishing sites.

Take a zero-trust approach to cybersecurity, and put your company in a position to minimize the possibility of intrusion. When DNS protection is in place, it can mitigate 33% of all data breaches. It’s a lightweight but powerful layer that will keep your entire organization safe.

Threats We Block

malware threat icon
Malware

Malware is short for “malicious software” and can be spread in a variety of ways such as forced downloads or malicious ad content. It includes viruses, worms, spyware, ransomware, and trojan horses. The most common way that malware gets onto a computer or other device is through surfing hacked sites. So the best way to protect your company from malware is to prevent your users from ever accessing these sites.

Zero Day Threats

DNSFilter is the best security product to protect against zero-day attacks because our proprietary AI tools are constantly scanning the internet for new sites that could potentially contain scams or malware. DNSFilter detects threats up to 80 hours faster than static threat feeds.

Phishing Attacks

Phishing and spear phishing attacks are a favorite among hackers because they are relatively easy to implement. They use email or chat (such as public Slack channels or Discord) to lure victims into a scam, or more commonly to a link where they will enter data or download malware. Phishing attacks can be broad and general, impersonating institutions like banks or hospitals, or they can be targeted and sophisticated, often impersonating employees inside your own organization. Because DNSFilter is constantly scanning the web for new malicious sites, we can prevent phishing attacks by stopping your employees before they hit a malicious site, or give a phisher their data.

Ransomware

Ransomware is software that allows hackers to encrypt files, networks, and computers remotely. They then hold your data hostage until your company pays a ransom. With the evolution of ransomware in key sectors like healthcare as well as the ubiquity that Ransomware-As-A-Service offers, this threat technique has become one of the top causes of cybersecurity incidents worldwide. In 2020 the average ransomware demand was $233,000 and they now make up around ⅓ of all security breaches. If your company doesn’t pay you risk data loss, or in some cases, data being sold on the darkweb. The key to ransomware protection is stopping the malware from being downloaded in the first place, which usually requires blocking the site that hosts the malicious content before an unsuspecting user can visit it and become infected.

Cryptojacking

A true 21st century threat, cryptojacking is the unauthorized takeover of a computer or network to “mine” cryptocurrency. Because new currency is created by computers using massive amounts of computing resources computational bandwidth is at a premium. Cryptojacking infects a distributed network of computers to utilize their computational bandwidth, slowing down the device and, at scale, driving up your energy costs. DNSFilter has a robust catalog of known cryptojacking sites, and domains that contain cryptocurrency references can be blocked in a single click.

Typosquatting

Thousands of people type Amazan.com into their browser every day. Turns out, the average internet user isn’t always the best speller. Bad actors take advantage of this by setting up malicious sites with domain names that feature common misspellings of familiar sites. Everyday we seem to discover new “Chase” login pages with an increasingly creative variety of typos (check out the fake sites here). DNSFilter protects the user from typosquatting by blocking access to domains that are known to contain malware or malicious content. Never worry about misspelled domain names again.

Man-in-the-Middle attacks

Have you ever visited a site that just looked off? Middleman attacks create a fake site that mimics a trustworthy brand login, and provides form fields where users enter their password, username, and potentially credit card data. The hacker then absconds with this data, leaving the user confused and exposed. Our AI-tool scans the UX of domains and includes logo matching, identifying when logos are being used on sites where they do not belong, ensuring that man-in-the-middle sites are quickly found, cataloged, and blocked.
