Address resolution protocol (ARP) poisoning, also known as ARP spoofing or ARP poison routing, becomes actual cyberattack events carried out over a Local Area Network (LAN) that sends malicious ARP protocol packets to a default gateway on a LAN. In other words, a Man in the Middle (MitM) attack allows an attacker to intercept communication between network devices. An attacker can receive data or remain undetected once the ARP packets have left the source network.
Most machines use address resolution protocol on a local computer network to communicate with each other. When an ARP poison attack is executed, an attacker sends out a fake ARP request, causing all devices connected on the target LAN to update their routing tables and associate the attacker’s machine and MAC address as the default gateway. When the user tries to access an internet address, they will get redirected to the device that belongs to an attacker and then served with falsified ARP messages.
Trustifi, a global leader in email security, provides several interlocking tools that help stop ARP poisoning and ARP cache attacks from hijacking email accounts and sessions.

How to Detect ARP Poisoning?
People often confuse ARP poison attack or spoofing with IP address spoofing, as they differ in meaning and purpose. The former means stealing someone else’s Media Access Control (MAC) address; the latter refers to the practice of corrupting the ARP table. These terms are sub-elements of cyberattacks on Internet protocol (IP) and MAC addresses.
ARP Spoof attacks occur when an attacker pretends to be another entity, such as a person or a business, to commit a crime. The technological implementation of ARP spoof involves websites, phone calls, emails, or more sophisticated approaches like DNS cache poison attacks, causing conflicting source IP addresses or Address Resolution Protocol ARP corruption.
The main goals of ARP poison are to illegally acquire confidential data, steal money, spread
malware protection-evading malware, bypass the wireless network security through malicious links or attachments, or redirect network traffic to perform denial-of-service attacks. Cybercriminals often employ spoofing to obtain critical information to launch more significant attacks, such as a man-in-the-middle attack or an advanced persistent threat. Hackers attempt ARP spoofing through every online communication channel to steal data, an individual’s identity, and assets.
How to Detect an ARP Cache Poison Attack
It is possible to check your ARP table to detect potential attacks by entering the following command line: “arp -a” on both Windows and Linux. This table will display both internet address and physical address columns (mapping of IP and MAC address). If multiple IP addresses have the same MAC address, you might be the victim of an ARP spoof attack.
One of the reasons why ARP cache poison attacks and spoofing are so dangerous is that they often serve as the launching pad for more advanced ARP attacks against their victim’s network and applications. Many ARP attack and spoofing prevention strategies have limited success, including network packet filtering, static ARP entries and cache, and IPv6 network addresses. MAC address filtering can block traffic from specific machines, networks, or devices. However, MAC spoofing can be quickly done in many operating systems, so any device can pretend to have a unique MAC address.
Once a cybercriminal executes a successful ARP poison attack (ARP spoof attack), they can then efficiently perform several attacks, including but not limited to the following:
DDoS attack (Distributed denial of service attacks)
This attack attempts to overload a server or the network with traffic so it cannot function properly. An attacker can use a given network IP address of the server they want to attack to perform a DDoS attack. With enough repeated successful ARP spoofing, the victim will be flooded with ARP traffic across their network switching infrastructure.
Session Hijacking Attacks
This attack occurs when an attacker uses an ARP spoofing tool to gain network access, allowing them to steal your session IDs. An attacker can then access your logged-in accounts using that stolen session ID. To prevent ARP poison attacks, you can use a high-quality virtual private network to mask your IP addresses and keep your online activity private and secure. A VPN is an encrypted tunnel that blocks your activity from the ARP poisoning attacker. You can also define a static ARP entry for IP addresses on your network and prevent devices from listening on ARP responses.
Man-in-the-Middle Attacks
This attack involves altering communications between two parties to appear to be communicating using the port, protocol, and source IP addresses. Hackers can intercept and manipulate web traffic and even push malware to a network device and a victim’s computer.
Email Hijacking
Cybercriminals use ARP poison attacks to take control of the email accounts of banks, financial institutions, or other companies. An attacker can monitor transactions and correspondence between the bank and its customers.
An attacker can spoof the bank’s email address and send customers emails instructing them to resend their credentials to an account controlled by the attacker.
Prevent ARP Spoofing Using Email Security To SafeGuard End-To-End Communications
ARP poisoning and ARP cache events impact organizations’ local network users. An attacker used ARP poison to corrupt the cache table and spoofing to hijack network connections. While stopping ARP poison attacks, including a man-in-the-middle, is often very challenging for SecOPs and NetOps teams, enable email encryption safeguards to protect end-to-end communications quickly.
Using One-Click Compliance and encryption from Trustifi, the sending user can encrypt the email first before leaving the secure gateway.
When the message is delivered to the destination, even if it is an ARP cache impersonation or session hijacking, the payload of the email is still encrypted and unreadable by the impostor.

Trustifi utilizes advanced encryption for every email sent and received on the platform, providing access to encryption technology directly integrated into a company’s preferred email provider.
Trustifi MFA Methods For Recipient Authentication
By enabling multi-factor authentication tools, you will ensure that emails are kept fully secure and can only be accessed by their intended recipients. Senders can encrypt emails with just a simple click of a button.
Recipients can securely and easily access encrypted emails in their inbox after verifying their identity with an additional authentication factor without creating new accounts or logging into third-party systems. This makes encryption much more accessible, making users far more likely to use it.
Many Methods To Verify The Identity Of The Email Recipient:
– PIN code sent via SMS or as a phone call
– Personal password
– PIN code sent via email
– Utilizing the recipient’s Single Sign-On (SSO) with Gmail, O365, or Yahoo
Core Benefits
The main benefit of two-factor authentication tools is that they verify the recipient. It does no good to go to great lengths to protect the contents of a message only to have it accessed by the wrong person. Trustifi’s two-factor authentication feature offers another layer of security to ensure that the intended recipient opens every email.
Trustifi Tracking Postmark Proof
Trustifi’s Postmark Proof Tracking tools offer the first viable alternative to Certified Mail and revolutionize how sensitive data is sent and tracked via email.
