Examples of successful phishing attacks
One of the most well-known phishing attacks occurred in 2016 when several users received fraudulent emails that appeared to come from PayPal. The message requested users to verify their account information, leading to the theft of many users’ data.
Another example is the 2020 attack, where criminals used fake websites that looked legitimate and tricked users into entering their banking information. This attack affected hundreds of victims and resulted in significant financial losses.
How to identify phishing?
Phishing refers to scam attempts aimed at obtaining personal information, such as passwords or banking details. Identification is based on recognizing suspicious messages and websites, which can prevent data leaks and financial losses.
Signs of suspicious emails
Suspicious emails may contain several warning signs that help identify potential phishing messages. Common signs include unusual sender addresses, poorly written content, and pressure to act quickly.

How to respond to a phishing attack?
Responding to a phishing attack requires quick and effective actions. Identify the attack, act swiftly, and ensure that you protect your information going forward.
Identify the attack
Phishing attacks can manifest in various ways, such as suspicious emails or messages. Pay attention to unusual links, incorrect addresses, or poorly written messages. If something seems suspicious, it is advisable to verify it before opening attachments or clicking links.
Attacks can also occur on social media or other platforms, so be cautious when sharing personal information. Always use official channels when contacting service providers or organizations.
Act quickly
If you suspect you have fallen victim to a phishing attack, act immediately. The first step is to disconnect the device from the internet to prevent any potential malware from spreading. This can prevent further damage and protect other devices on the network.
Do not delay; change your passwords immediately, especially for accounts you may have accessed during the attack. Ensure that the new password is strong and unique so that it is not easily guessed.
Report the incident
Report the phishing attack to your organization or service provider. This can help other users avoid similar attacks. Most companies and services provide specific channels for reporting suspicious activity.
If the attack has occurred on your bank account or other financial accounts, also notify your bank. They can help secure your account and prevent potential fraud.
Change passwords
Changing passwords is one of the most important actions after a phishing attack. Use strong passwords that include both uppercase and lowercase letters, numbers, and special characters. Avoid passwords based on personal information, such as birthdays or parts of your name.
A good practice is to change passwords regularly, for example, every few months, and to use different passwords for different accounts. This reduces the risk that one leaked password leads to multiple account thefts.
Check accounts
Ensure that you regularly check all your accounts. This means you should check your bank account, email, and social media accounts for any suspicious activity. If you notice anything unusual, such as unknown transactions or messages, act immediately.
If you use multiple accounts, keep track of their usage and ensure that all information is up to date. This can help you detect potential issues earlier.
Use two-factor authentication
Two-factor authentication (2FA) adds an extra layer of security to your account. This means that even if someone obtains your password, they cannot log into your account without another verification method, such as a text message or app. Enable this feature on all accounts that offer it.
Two-factor authentication is especially important for email and banking accounts that contain sensitive information. It can prevent attackers from accessing your account even if they have your password.
Ensure security software is up to date
Keep your security software up to date and ensure it is installed on all your devices. Good programs can prevent malware from accessing your device and protect you from phishing attacks. Regularly check for software updates and run scans on your devices.
Additionally, consider using a firewall, which can provide extra protection against online attacks. A properly configured firewall can block suspicious traffic and protect your data.
