Phishing is a nefarious practice where cybercriminals attempt to trick individuals into revealing sensitive data on bogus websites. These attacks are often carried out through seemingly legitimate emails, text messages, or even social media sites and posts, luring victims to click on a fraudulent link and provide sensitive information. The sophistication of these deceptive emails can be so high that even tech-savvy individuals might not recognise them.

The successful execution of a phishing attack can lead to significant financial losses, data breaches, and even severe damage to the company’s reputation. Therefore, gaining knowledge about phishing threats and adopting effective measures to prevent phishing emails is essential, especially on widely-used platforms like Outlook.

Phishing is not only about illicit money acquisition, it also involves unauthorized access to sensitive data such as passwords and financial information. The purpose of these attacks is often to carry out more targeted and potentially damaging spear-phishing attacks. Understanding the various types of phishing attacks and the tactics employed by cybercriminals is the first step towards building a robust defense against these threats.

Types of Phishing Attacks

Phishing attacks come in many forms, each with its unique features and potential harm. One such type is whaling attacks, a form of spear-phishing that specifically targets high-profile individuals such as executives or celebrities. The goal? To steal sensitive information. In a whaling attack, cybercriminals:

  • Conduct extensive research to personalize their emails

  • Use urgent language to prompt actions

  • Manipulate email domains to appear legitimate when soliciting confidential data like payroll or financial information.

Another type of phishing attack is malware phishing. It involves the use of fake emails, with malicious attachments that appear trustworthy. If a recipient opens these attachments, their IT systems could be compromised and become paralyzed.

Spear-phishing attacks also exist, which are direct, personalized attacks on specified individuals, in contrast with generic phishing attempts that aim at a wide range of victims. Recognizing these different types of attacks is an integral part of your defense strategy against phishing.

Common Tactics Used by Cybercriminals

A range of ingenious tactics are employed by cybercriminals in their phishing attempts. Some common strategies include:

  • Impersonating known or trusted entities like Google or Wells Fargo to weave a credible story that tricks recipients into actions like clicking on a link or opening an attachment

  • Sending phishing emails that contain threats or a sense of urgency, pressuring the recipient to act quickly to avoid penalties or to claim a supposed reward

  • Creating a sense of panic and urgency, leading to hasty actions without proper scrutiny

It is important trick users to be aware of these tactics and to exercise caution when dealing with suspicious emails or text messages either.

Another tactic involves enticing victims with promises of prizes or discounts, luring them into providing personal information or engaging with malicious links. Recipients should be wary of any unsolicited emails with requests for installing programs or following links to update payment information, which are common tactics involving fake websites or malicious attachments in phishing emails. Comprehension of these tactics enhances your ability to protect yourself and your organization from becoming victims of phishing scams.

Configuring Outlook’s Built-in Security Features

Illustration of Outlook security features - How to stop phishing emails

Despite being a widely-used platform for both personal and professional communication, Outlook is not impervious to phishing threats. Fortunately, it comes equipped with built-in security features that can be configured to protect against phishing attacks.

These features include Junk Email Filter, which automatically scans incoming emails to assess if they should be marked as spam. Regular updates of Outlook are advisable to ensure the newest security features and the latest version of the spam filter are installed.

In addition to filtering junk emails, Outlook also allows users to adjust Microsoft Defender for Office 365 anti-phishing policies to avoid mistakenly allowing phishing messages by inaccurately placing domains on the Allow list.

By tuning anti-phishing protection and regularly monitoring the X-Forefront-Antispam-Report header field for any indication of skipped spam or phishing filtering, users can significantly enhance their email security. We will now examine how to modify junk email settings and craft safe and blocked senders lists in Outlook.

Adjusting Junk Email Settings

When learning how to stop phishing emails, the Outlook’s Junk Email Filter plays a crucial role in spam filtering, which can protect against phishing emails. You can adjust its settings to guide the filter in identifying spam.

For instance, trusted senders can be added to the safe senders list to ensure their messages are not misclassified as junk. Conversely, you can add suspicious email from addresses or domains to the blocked senders list to automatically send these emails to the spam folder.

Modifying your safe senders or blocked senders list is straightforward. Simply select an item and use the Edit or Remove options to update the list accordingly. Furthermore, by enabling the ‘Automatically filter junk email’ setting under Block or allow, Outlook can filter spam without manual intervention, greatly reducing the burden on users.

Creating Safe Senders and Blocked Senders Lists

Forming safe senders and blocked senders lists in Outlook serves as an efficient method to manage your emails. To add someone to your Safe Senders list, follow these steps:

  1. Navigate to the Home tab

  2. Click Junk, then Junk E-mail Options

  3. On the Safe Senders tab, check ‘Automatically add people I e-mail to the Safe Senders List’

This helps prevent trusted emails from multiple accounts from being mistakenly treated as junk. However, if you want to prevent emails from your contacts being automatically treated as safe, you can clear the ‘Also trust email from my Contacts’ checkbox under the Junk Email Options.

To block unwanted email senders, you can immediately block a specific spammer by right-clicking the message and choosing Junk > Block Sender, or go to the Blocked Senders tab in Junk E-mail Options to manually enter their email address, domain, or ban an entire domain using the @domain format. By creating and maintaining these lists, you can effectively manage your email traffic and keep your inbox clean and secure.

Enhancing Email Security with Advanced Tools

Though Outlook’s inherent security features offer substantial protection against phishing attacks, supplementing email security with advanced tools bolsters the defense layers. Microsoft 365 Advanced Threat Protection (ATP) and Defender for Office 365 are two such powerful tools.

They provide additional security features such as ATP Safe Links, ATP Safe Attachments, and anti-phishing policies employing machine learning and impersonation detection algorithms. These features can help protect against sophisticated phishing attacks that might bypass traditional security measures.

Defender for Office 365 extends protection across email and Microsoft Teams against phishing and other cyberthreats. It offers the following benefits:

  • Threat protection policies

  • AI-based detection of malicious content

  • Features for investigating, responding to, and remediating cyberattacks

  • Configuration insights

  • Cyberattack simulation training

Organizations using Defender for Office 365 can take advantage of these features to enhance their cybersecurity defenses.

Next, we will explore how the implementation of email encryption and the utilization of multi-factor authentication can further bolster email security in Outlook.

Implementing Email Encryption

.Email message encryption is a powerful tool to protect against phishing attacks. By keeping email messages encrypted within Microsoft 365, you can ensure that sensitive information is safe from unauthorized access. offers two encryption options: ‘Encrypt’ to keep messages encrypted within Microsoft 365, and ‘Encrypt and Prevent Forwarding’ to also prevent copying or forwarding of the same email message.

Encrypted messages can be read directly in, the Outlook mobile app, or the Mail app in Windows 10 by or Microsoft 365 account holders. For recipients outside of or Microsoft 365, they can read encrypted messages using a temporary passcode that is provided inbound emails. Implementing email encryption is a significant step towards enhancing email security and thwarting phishing attacks.

Utilising Multi-Factor Authentication

Another advanced tool that can significantly enhance Outlook security is multi-factor authentication (MFA). MFA adds an extra layer of security by requiring more than just a password to access an account.

This could be something the user knows, the same password such as a password, something the user has, like a phone or hardware token, same password, and something the user is, for example, biometric verification.

MFA makes it more difficult for scammers to access an account even if they have obtained the username and password. To set up MFA, users should navigate to their account security settings in Outlook and follow the provided prompts to add an extra verification method.

Once MFA is enabled, Outlook will require an additional factor, like a verification code sent via SMS or generated through an authenticator app, when a user attempts to sign in from an unrecognized device or location. Utilising MFA is an effective way to enhance email security and safeguard your accounts against phishing attacks.

The recognition and reporting of phishing emails are vital components in thwarting phishing attacks. Signs of a phishing email in Outlook may include suspicious sender addresses, incorrect grammar, and bizarre requests from the sender. If you come across a suspicious phishing email, you should report it as phishing using the ‘Report phishing message’ option in Outlook.

If you’re uncertain about the email’s legitimacy, you can report it as a security risk, spam, phishing, or malicious content through Outlook’s ‘More options’ feature. Next, we will examine in detail how to identify warning signs and efficiently report phishing attempts.

Identifying Red Flags

Identifying red flags in phishing emails is a critical skill that can help you avoid falling victim to scams. Red flags related to sender details may include emails marked as [External], domains in the address not matching the reputable company, the presence of a ‘?’ in the sender’s image, and a ‘via’ tag showing a discrepancy in the sender’s address. Other indicators of phishing emails can be poor grammar and spelling, unfamiliar greetings or tones, and using generic greeting or salutations like ‘Dear sir or madam’.

Phishing emails often convey a sense of urgency or request actions that deviate from the norm, such as following links, sharing personal or bank details with, or even initiating phone calls. They may also initiate contact without prior interactions, offering prizes or discounts. Attachments and links that appear as suspicious activity should be treated with caution, as they are common methods used by phishers to compromise security.

When a text message just seems unusual, it’s advised to contact the person or company through a known, independent channel to verify the text message email’s legitimacy and consider reporting and deleting the message if it’s from an unknown source or account.

Reporting Phishing Attempts

Reporting phishing attempts is a critical step in combating these cyber threats. In Microsoft 365 Outlook, you can report phishing emails by selecting the suspicious message and using the ‘Report message’ feature to classify it as phishing.

Reporting suspicious stop phishing emails to organizations like the Anti-Phishing Working Group is encouraged, aligning with the mantra ‘See something, say something’, to aid in incident response and risk mitigation.

In, you can report phishing attempts by selecting the suspicious phishing message and navigating to Junk > Phishing > Report, which reports but does not block the sender.

To prevent future messages from the sender, you should add them to the blocked sender’s list. Within Outlook, users can configure junk email reporting options to ‘Ask me before sending a report,’ ‘Automatically send reports,’ or ‘Never send reports,’ depending on their preferences for contributing to Microsoft’s research and improvement of email protection technologies.

  • Changing passwords

  • Enabling multi-factor authentication after suspecting a phishing attack

  • Using antivirus software to scan your device and remove any malware or spyware that may have been installed

If a suspicious attachment has been downloaded, here are the immediate actions to be taken:

  1. Disconnect your device from the internet to prevent further damage.

  2. Document all details related to the phishing attack, including the information that was potentially shared with the attacker.

  3. Report the incident to local law enforcement, especially if you’ve lost money or there’s suspicion of identity theft.

We will now examine in detail the processes of reporting and recovery post a successful phishing attack.

Immediate Actions

Recognising a phishing attack is just the first step. Once a phishing attack is detected, immediate actions need to be taken to secure the compromised bank account and prevent further damage. Changing the passwords of all affected accounts should be the first step. It’s also recommended to create unique passwords for each account to ensure one compromised password does not lead to additional vulnerabilities.

Enabling multi-factor authentication (MFA) on your Outlook account can significantly decrease the risk of identity theft and unauthorized access, providing security even if your account password is known to someone else. Neglecting to take these immediate actions can lead to further breaches and possibly lead to a cascade of threats that could have been avoided.

Reporting and Recovery

After taking immediate actions, the next step is to:

  1. Report the phishing scam to the company that was spoofed.

  2. Report the phishing scam to appropriate authorities like the Anti-Phishing Working Group or the FBI’s Internet Crime Complaint Center.

  3. If your credit cards or bank accounts are compromised, it’s critical to contact the financial institutions to alert them to potential fraud.

In the aftermath of a phishing attack, it’s crucial to secure your your bank account details and personal information. You should also contact one of the major credit agencies and your credit card companies to put a freeze on your credit report and protect your credit card amount against fraudulent charges. If you visited a suspicious website during the phishing attack, use Microsoft Edge’s ‘Report unsafe site’ feature to report it.

Sharing your experience, including any personal or financial information that may have been targeted, can help others avoid a similar phishing scam and contribute to collective cyber safety awareness.
