What is Phishing?

Phishing is a type of social engineering attack used to steal user data, including login credentials and credit card details. Scammers obtain sensitive information or data from the user, by disguising themselves as a trustworthy source. The victim is duped into opening an email, instant message, or text message. The recipient then clicks a malicious link, leading to the installation of malware, the freezing of the system if part of a ransomware attack or the revealing of sensitive information.

As an example, is the 2018 phishing attack targeting Netflix users. The phishing email purported to be from Netflix and warned recipients that the company were unable to access the customer’s billing information. The message requested customers to click on a link to update their payment method. That link, of course, directed the customers to a fake website created by the scammers.

That being said, not all phishing attacks look and operate in the same way. Phishing scams can take a variety of forms and often have different goals. Some phishing email might try to trick users into clicking a link that leads to a fake website as in the Netflix scam already mentioned. These fake websites install malware allowing hackers to steal personal or senstive information or take control of your device.

What is Spear Phishing?

Spear phishing is an email scam targeted towards a specific individual, organization or business. It is often used to steal data or install malware on a targeted user’s computer for malicious purposes. A typical spear phishing attack includes an email and attachment. The email includes information specifically related to the target, often including the target's name and position within the organization. Most huge data breaches have a social engineering component augmented by detection evasion techniques.

The Evolution of Phishing

The evolution of phishing is, of course, in line with the evolution of technology. Until recently, a typical method used in phishing emails to install malware on a device, was to carry the malware as an infected attachment, usually an Office document or PDF. This method matched employees use of emails to share documents. This method was successful and continues to this day.

However, as the use of online collaboration portals increase, employees are less likely to share documents via email. In response to this change, cybercriminals are changing their tactics. Instead of phishing emails containing malware-infected documents, scammers are piggy-backing on the way online collaboration portals work. That is, sending emails with shared links to documents and files. These shared platforms are at risk of being misused by phishing campaigns via malicious links in fake emails branded to look like the portal. A current focus of these phishing scams is on SharePoint and OneDrive.

Phishing is as much about human behavior as it is about technology. Cybercriminals know that tricking users into performing an action can effectively get them the results they need. Getting the human user to perform this action relies on ‘trust’. It is this trust element that scammers use when they spoof well-known brands, such as SharePoint and OneDrive.

Protecting against Phishing Attacks with an Anti Phishing Filter

The first line of defense against phishing scams is email protection. Email messages created by attackers sometimes have a recognizable spoofed email sender address, and some phishing attacks are designed to ensure the message looks like it’s from an official source. Recipients not trained to look for phishing emails click links that takes them to an attacker-controlled server. DMARC (Domain-based Message Authentication, Reporting and Conformance) is a security framework that detects and stops these attacks.

DMARC is a set of cybersecurity configurations that use a combination of digital signatures (DKIM) and DNS verification using Sender Policy Framework (SPF). DomainKeys Identified Mail (DKIM) adds public-private key encryption that adds a signature to the header in an email. The owner of a domain adds a verification key as a DNS entry and SPF protocols at the recipient email server perform a lookup for this verification entry. Only valid IPs can then send an email on behalf of the sender’s domain. SPF eliminates an attacker’s ability to send spoofed email messages.

DMARC works in conjunction with email filters and DNS-based content filters so that users are unable to access attacker-controlled websites. With DMARC, the messages should not be able to reach the user’s inbox. Messages blocked by DMARC rules are quarantined where the email administrator can review it for any false positives. Should a message return a false negative, the malicious content would reach the user’s inbox. DNS-based content filtering would trigger and block the user from accessing the website where an attacker phishes for user credentials.

Without the right cybersecurity tools in place, organizations are vulnerable to phishing scams. This malware could cost an enterprise millions in disaster recovery and ransom fees if they’re paid. The only way to avoid them is to have the right email security using DMARC and content filtering.

Benefits of a Phishing Filter

More than 90% of all cyberattacks start with a phishing email. Cybercrime is a powerful tool for criminals looking to steal data or demand ransom money. Phishing continues to be the most common form of cyberattacks, however, phishing can be prevented by implementing an email phishing filter for email protection.

The main reason an organisation deploys an anti-phishing filter is to protect the business and its employees from phishing attacks. However, there are lots of benefits of an email phishing filter. Here are some of the many benefits:

Protecting Users On and Off the Network

Remote working is known to be a strain on communicating and collaboration in the workplace, hence, it’s now trickier for employees to identify a phishing email when working remotely. Where an employee would previously ask a colleague sitting next to them about the suspiciousness of an email, that has been removed since remote working. However, with an anti-phishing filter, employees will be protected from phishing emails no matter their work location, whether they are in the office or working from home.

Increase in Employee Productivity

Implementing an email phishing filter will significantly reduce the number of emails an employee will receive. This means that they will spend less time sieving through emails, deleting spam emails, and more time working or responding to real emails. Systems administrators will also see a rise in productivity, as a phishing email protection solution will manage all spam emails, instead of a singular person continuously updating whitelists and blacklists.

Preventing BEC attacks (Business Email Compromise)

An advanced phishing email protection will not only stop phishing emails entering a user's mailbox but will identify if an account has been compromised. An anti-phishing filter such as SpamTitan Cloud not only scans inbound emails for suspicious messages but scans outbound emails. If an account has been comprised, the anti-phishing filter will block emails from being sent and will protect the domain authority.

Data Loss Prevention

One of the risks associated with phishing attacks is data loss. Business data and personal data are extremely valuable to cybercriminals as they can either (1) sell the information on the dark web or (2) demand a ransom to restore the data. Consequently, with an email phishing filter, phishing emails are blocked, reducing the risk of an employee clicking on a suspicious link, resulting in a cybercriminal installing malware onto the device to gain access to sensitive data.

Ransomware Prevention

Similar to data loss prevention, if criminals can’t get access to sensitive information or gain access to business systems and infrastructure via phishing attacks, the risk of ransomware is diminished. It’s important to note that organisations should use a layered defense approach for ransomware prevention, and not solely rely on a phishing filter. A DNS filter will prevent employees from accessing malicious websites to help the defense against ransomware.

Phishing is one of the most common and successful ways to infect an organization with malware. Employees instructed not to click on URLs in unexpected emails still can't seem to resist the temptation. Once clicked these malicious URLs can lead to data breaches, ransomware and other devastating threats. SpamTitan Plus Plus is an advanced phishing protection solution from TitanHQ.
