How to avoid spearphishing attacks

Don't be that Fish

February 10, 2020

Spearfishing is the name of a network spoofing attack method that targets a person or organization in order to steal sensitive information -- such as financial information or email account details. Cyber ​​criminals often use this technique to install a malware on the target computer. Unlike a regular phishing attack, spear phishing emails appear to come from friends or legitimate companies like PayPal and Google. The spearfishing email comes from a trusted source; it contains a link to some fake website asking you to release some confidential information or download their software.

According to industry reports, the overwhelming majority of business security breaches result from such spearphishing attacks. Larger companies are also susceptible to similar attacks. The recent CNN Spearfish Hack is an example of how everyone is on the path to these threats.

Phishing attacks have been around (almost) forever. As cyber criminals make huge profits from these scams, there is excellent reason for such attacks to continue for a long time. There are ways to ward off falling victim to these frauds. One such way is to use an external service: sites such as fhishprotection offer businesses and organizations anti-phishing solutions.

However, if you are a little scrupulous on the Internet, you can avoid these attacks. Here are some ways to avoid getting caught up in spearphishing scams.

Implement DMARC authentication

Nothing is impossible in this digital age. Suppose you received an email from ceo@company.com and you received it from a company address, we should not trust it. We can block cyber ​​criminals from the field of email. Spearphishing emails look authentic and lead to successful phishing attacks. Implementing
DMRC (Domain-Based Message Authentication, Reporting and Optimization) can help prevent these attacks.

This technology relies on the SPF (Sender Policy Framework) and DKM (Domaincase Identified Mail) standards established for email authentication. It analyzes the email against its database, and if no record matches the sender’s email, it rejects the email. They submitted the report to the Security Admin. All major email providers, Google, Yahoo and AOL use DMARC authentication to ensure that fake and deceptive emails do not reach users.

This is a great technology, but it is not foolproof. In May 2017, hackers launched a successful phishing attack on Google, which sent Google document links to Gmail users. Google stopped the attack within an hour, but the damage was already done. The company is taking special steps to prevent another Google Spearfish attack and is strengthening security.

This does not mean that the DMARC cannot protect you. It is still useful. This is just one of many steps you can take to protect yourself from cyber attacks.

Encrypt sensitive data

Encryption is a great way to protect yourself from falling victim to these frauds. It ensures that only allowed people have access to your data. Encrypt the data on your device with a full disk encryption. You can buy encrypted drives to protect your data. When using the Internet, consider signing up for a VPN to encrypt Internet traffic. You can encrypt your data in the cloud using automated tools available on the Web. Once your data is encrypted, even if your account gets hijacked, your data will be safe.

Doubt the grammar

Businesses and companies spend a lot of money on copywriters to create emails with the right grammar, great content, and headline. Emails with bad grammar, punctuation and errors are unlikely to get them from you. If you get such an email with broken English, some inexperienced scammer may send it. You receive a link in the email, which leads you to a fake website that requires sensitive information. Be careful not to give them any of your material.

Check the site’s SSL credentials

When you visit a website, make sure it starts with “https”. SSL (Secure Sockets Layer) ensures that data is transmitted over the Internet in encrypted form. Never fill in your passwords or other confidential information on a site that does not have a valid SSL certificate. It is very effective and helps prevent spear fishing attacks. Often people don’t check SSL certificates when filling out information in one form. That makes them easy targets and it is why they become prey to these crimes.

Take advantage of AI

Implement an AI system that prevents spear phishing attacks such as brand deception and business email compromise. Machine learning can analyze data and find patterns in it. With advanced AI algorithms, machine learning can identify patterns and vulnerabilities that lead to an attack. When combined with machine learning and powerful disorder detection algorithms, spearfishing can help limit the spread of attack.

Multi-factor authentication

Another great way to prevent spearphishing attacks is to enable multi-factor authentication. This will add an extra layer of security to your data. Most businesses use this technology. Sites like Google are already offering two-step verification to its users. So even if hackers have some information about you, they must overcome another level of security. MFA requires at least two identifiers. This could be a randomly generated token, an OTP or an additional login of your number. Run it wherever possible. You have extra security.

Keep your system up to date

It is important to keep your system up to date. Make sure you are running the latest version of the operating system. If you’re working on Windows, Microsoft is always worried about user security. They are always updated for security patches so that your security does not come into force. Security patches are essential because they can recognize the latest fishing methods and protect you from being attacked. So, make certain your system is up to date and install security patches.

Conclusion

Be very wary of the links you visit and learn about the latest spearfishing techniques. If you are mindful enough, you can avoid spearfishing.
