Phishing is one of the oldest threats on the internet and remains one of the main security problems within this environment. Since it does not require sophisticated resources to target its victims and divert information, the cyber threat is combated with numerous tools, such as the DNS firewall.
This strategy does not require extensive technical knowledge and can be disseminated across different platforms. Phishing is one of the most common cyber attacks and can cause countless problems for companies and users . In addition to diverting sensitive information, this threat also allows the implementation of malicious files and viruses on devices, causing technical problems and unavailability of services.
Understand how phishing can harm your business:
For this reason, it is very important that companies prepare to deal with this threat in the best way possible , relying on the best tools on the market to prevent this trap from causing problems for the business. See the complete content below and discover how the DNS firewall can help your company ensure its digital security.
What is phishing?
Phishing threat used to steal access information, financial data, confidential documents and even to install malicious software. Using social engineering , cybercriminals develop fake emails posing as trusted companies to deceive their victims.
One of the most used strategies in applying this scam is simulating emails from financial institutions and e-commerces , leading the user to believe that it is a legitimate contact. This email is usually accompanied by a malicious link that directs the victim to a fake page or causes them to download a malicious file.
Because it is a simplified strategy, phishing continues to be widely used by cybercriminals to carry out scams and steal confidential information. According to the report prepared by Kaspersky , in 2022 Brazil suffered approximately 76 thousand fraud attempts through phishing attacks.
This same report brought worrying data regarding the distribution of malicious messages, demonstrating that cybercriminals have been using Whatsapp, Telegram and Viber to maintain an even more comprehensive strategy of distributing false messages . This data demonstrates how phishing is still an active threat and must be combatted through more efficient security strategies.
Is it possible to avoid phishing?
Firstly, we need to understand that phishing, despite being a simplified threat, can also cause immeasurable losses for companies. Since the emergence of the General Data Protection Law , concerns about the confidentiality of sensitive information have become a priority within businesses.
Therefore, it became necessary for companies to implement more sophisticated resources to block unauthorized access attempts. In addition to preventing users from creating points of vulnerability in the company's networks and devices.
It is necessary to establish, in addition to an internet usage policy , the implementation of some rules of conduct that help to avoid most malicious contacts, such as:
Keep an eye on email addresses and contacts
Although cybercriminals can create emails very similar to those used by legitimate companies, it is impossible to properly disguise sender emails and contact information. Although the threat successfully replicates the name of the institution and its visual characteristics , the sender's address does not have a real connection with the institution and is easily identified.
A valuable tip is to check the presence of a large extension in that email address, containing abbreviations or numbers. It is also important to check the content after the at sign, that is: whether it really is a corporate email or whether it is a common account on an email platform, which deserves even more attention.
Spelling errors
It is very common that within phishing emails we find very obvious spelling errors. Legitimate companies rarely make grammar or spelling errors, so the presence of one of them could characterize a phishing .
Be careful with links and files
It is very important to avoid accessing links sent by email from untrustworthy senders and also with possible attachments . In addition to impersonating companies and financial institutions, cybercriminals can also gain access to your contact list and disguise their fake emails as someone in your circle of family, friends or co-workers.
These links can redirect you to false pages and make you provide access data or banking information , causing great losses for you and the company. Attachments can be malicious files that corrupt devices and divert information.
Phishing attacks are sophisticated
For many years, this type of threat appeared due to a lack of knowledge and preparation among internet users. For this reason, even the most simplified attempts managed to obtain results, based on the victims' lack of preparation.
However, over the years phishing attacks have become more targeted. Using social engineering, cybercriminals began to develop more personalized traps to target victims and users of specific companies and organizations.
Depending on the criminal's objective, social media data can be collected to build an assertive and efficient trap , creating a realistic email and directing the attack to a specific victim. Personal information is used in the construction of this email or contact attempt, so that accessing the links or downloading the attachments is more likely.
The improvement in cybercriminals' strategy has also been favored by the emergence of new technologies, so that these threats are becoming increasingly difficult to detect , as is the case with automation resources. As a result, cybercriminals are able to send millions of phishing emails simultaneously.
Use technology as an ally
In addition to implementing these precautions into the company's routine, it is also necessary to have technological resources that help keep networks and devices more protected, such as the DNS firewall. Although there are anti-phishing measures that help reduce the incidence of this type of attack, in most cases this strategy is insufficient.
This is because there are some problems that are easily overcome by cybercriminals, such as:
- Cybercriminals can easily generate new fraudulent domains, so blacklisted URLs cannot keep up with current threats.
- Email filtering relies on content inspection , signatures, and display names.
- Even with the employee education process, it is still possible to create points of vulnerability.
- Commercial email compromise filters can only be applied to email tools , disregarding threats that can arrive through web pages, applications and social networks.
- Among other problems.
For this reason, the DNS firewall has proven to be a complete and well-structured tool for detecting and controlling phishing threats within your company. With threats becoming increasingly sophisticated and structured, it is essential to have the correct tool to keep your company and its data always protected.
