Key Red Flags in These Phishing Samples
A fake email that claims you have reached your email quota or your email account is suspended may exhibit any of the following warning signs:
1. Email messages asking for action to be taken within very short time frames (e.g., "immediate response required", "last opportunity")
2. Sender email addresses that contain typos or misspellings (e.g., [email protected], instead of [email protected])
3. Use of non-specific salutation such as "Dear User", versus addressing your specific identity
4. Email requests to click on a hyperlink or download a file to "confirm" or "update"
5. Poor sentence structure and spelling/grammar errors, randomness in branding
6. When hovering over hyperlink, use of shortened or suspicious URL
7. Instilling a sense of urgency to respond quickly so that the recipient will not lose their email account
Legitimate companies will not send out unsolicited emails to warn of possible impending suspension of an email account, or request users' passwords or any other private information through a hyperlink included in unsolicited emails.
How These Fake Lures Typically Work
The attack pattern of these imitation lures is straightforward and effective:
1. An incoming fraudulent quota exceedance email presenting no evidence of verification or assurance of authenticity is received into the inbox.
2. The panic reaction causes you to click on the link before you can consider your reaction to what was just received.
3. The clicked link will direct you to a highly believable imitation of a genuine login page, which captures your credentials.
4. The email could also contain links that will force your computer to install malware, or any other type of phishing attack.
The most advanced versions coming out by 2026 will utilize AI-generated text in order to enhance grammatical, spelling errors and enhance individual personalization based on past data breaches.
How to Protect Yourself from These Scams
To avoid falling victim to these types of attacks follow these recommendations:
1. Never click on any links in any urgent quota overage or quotation suspension notices, always manually log in to your account by using the official website.
2. Implement two-factor authentication (2FA) wherever possible.
3. Use a password manager by generating a unique and secure password for all online accounts and use different credentials.
4. Inform your email service provider of any suspicious email you have received or report any suspicious emails using the built-in phishing report function.
5. Before clicking on a link in an email always hover your mouse over the link to verify its actual destination/website.
6. Maintain the most recent versions of both your e-mail application and antivirus software.
If you are an organization, regularly provide security awareness training for all employees to assist them in recognizing these types of lures at the earliest stage possible.
What to Do If You Clicked a Suspicious Link
If you have clicked the link for an email quota has been exceeded or the suspension of your account, please do the following:
1. Change your password immediately using the official website (not through the email).
2. Enable/review two-step verification settings.
3. Run a malware scan of your computer.
4. Keep an eye on your account for unusual activity.
5. Report this email to your email service provider and possibly to the authorities — e.g., the Federal Trade Commission.
Acting quickly can help minimize any negative consequences associated with this event.
