What counts as phishing?
Any attempt to obtain information or money through a fraudulent email is considered phishing. Phishing emails masquerade as a real email from a trusted source: a person or, more often, a company like Amazon, Google, or PayPal. These emails create a sense of urgency for users to follow a link to a page where they will enter their passwords to avoid an adverse event, such as closing their email account or dealing with a fraudulent charge, or to recheck their account balance. One account. .
Once they log in, their information may be stolen or their computer may be infected with malware or ransomware. In some cases, cybercriminals use the data to hack accounts, pocket money, or make fraudulent purchases.
Phishing scams typically involve link manipulation – the use of misspelled URLs that look like legitimate URLs. Phishers often use embedded images in emails instead of text to help bypass filters. More sophisticated approaches may involve a covert redirect that uses a login popup on a legitimate website.
There are some common approaches:
- Spear phishing is a targeted attack against a specific person or company. These attacks typically involve gathering information about the target(s) in advance to better design phishing emails to manipulate potential victims.
- Clone phishing uses a previously sent legitimate email with an attachment or link whose content and address are cloned. The link/attachment is replaced with a malicious site or dangerous attachment.
- Whale strikes are directed against top executives or other high-profile targets. These scams typically take the form of important business or legal emails and have even included fake subpoenas.
- SMS phishing, or smishing, uses mobile phone text messages to steal recipients' personal information.

Designated email addresses
If your business regularly receives legitimate emails for financial transactions, you can set up specific email addresses just for these requests. Limit the exposure of these addresses on public sites, which can help reduce your phishing footprint.
Code Names/Code Words
Code names aren't just for spies. For example, employees or customers can set specific email formats or keywords for correspondence so the recipient knows the email is legitimate.
Apply email policies
Set policies to minimize the number of sensitive transactions that occur through email. If employees know that financial authorizations should only be done in person or over the phone, they are unlikely to fall for a phishing attempt to trick them into doing it by email.
Phishing is a growing and ever-changing threat, so it's essential to stay up to date with the latest threats and the steps your organization can take to mitigate these attacks.
