Cibercrime invadiu as empresas em Portugal: como reagir?

Em 2021, a Check Point Research registou, nas organizações portuguesas que acompanhava, uma média de 881 ciberataques por semana por organização. O valor foi 81% superior ao de 2020.

Nos dados de 2021 da Check Point Research, divulgados em janeiro de 2022, destacaram-se a educação, a saúde e a administração pública entre os setores mais visados.

Today I'm going to teach you how to protect your company, so that you won't be another victim of this escalating cybercrime. And so that you understand the importance of effective protection, let's look at what has happened to companies that we all consider impenetrable.

Portugal: which companies under attack?

Entre os exemplos de cibercrime citados neste artigo estão as seguintes empresas portuguesas:

  • SIC
  • Express
  • Continente
  • SONAE
  • Vodafone
  • TAP
  • Cofina
  • Sport Lisboa e Benfica

And these were not simple attacks, resulting in the loss of a computer mouse.

The attack on Vodafone caused firemen, letter carriers and some hospitals to lose the ability to respond to users. The Judiciary Police was unable to receive complaints. Even the ATMs of the Multibanco network stopped working!

"One of the hospitals affected was the one in Matosinhos, which was prevented from sending automatic messages with calls for appointments and exams and test results to Covid-19."

- Mariana Marques Tiago in Public

Other Portuguese organizations affected include:

  • Portuguese Sea and Atmosphere Institute
  • EMEL
  • INEM

Mário Vaz, CEO of Vodafone in Portugal, explains that thousands of users lost access to calls, text messages, mobile data and, in some cases, even access to television channels was conditioned.

And the chaos is not limited to the Vodafone network. The attack on the Impresa group, which includes SIC and the Expresso newspaper, was conducted by the Lapsus hacker group and resulted in thousands of destroyed archive files.

It was natural to think that these attacks were being conducted by someone planning to exterminate free journalism in Portugal. But the BBC claims that the Lapsus group is led by a young man of only 16!

The criminal organization had already been associated with the attack on the Ministry of Health in Brazil, and this time they managed to hijack the Twitter account of the Expresso, in addition to the website www.expresso.pt. This was how the page looked when trying to access it:

The same group claimed attacks on the Portuguese Parliament and Tap. And allegedly conditioned access to websites of the Cofina group and affected the portals of:

  • Record Newspaper
  • Correio da Manhã
  • Jornal de Negócios
  • Sábado Magazine
  • CMTV

The feeling that remains is that of an entire country in a state of siege, without access to essential information and services, because of a teenage prank. And if it was hard to think that companies are so vulnerable and that they need to protect themselves more than ever, the more than evident proof is here.

"Our country's greatest institutions have been vandalized in the snap of a finger."

- Nuno Diniz - Morebiz Founder

As a business owner, the question that arises from this observation is only one: how can I ensure the minimum protection requirements for my company? Read on to find out.

What threats can my company face?

There are two types of cybercrime commonly used in an attack on companies or institutions: phishing and ransomware. We have written about both, but today we will summarize the information you need to defend your company.

Phishing: The Essentials

Phishing is known as the criminal act of tricking a user into sharing confidential information such as passwords or credit card numbers.

As infishing, there is more than one way to "catch" a victim. But using an email posing as a trusted person or organization - such as a bank or government entity - is still the most common practice.

Os cinco passos de um ataque de phishing

This is the usual sequence of crime:

  1. The victim opens the email because he finds a scary or urgent subject in his inbox;

  2. The email asks the victim to download an attachment and/or consult a website and do a certain urgent action;

  3. The user clicks and enters a trustworthy looking website;

  4. The website asks the user to log in or enter bank or personal details;

  5. This information is later sold, used to empty bank accounts and/or extort the victim

The big difference between a user who knows how to identify this type of threat and one who stumbles at every trap is cybersecurity training.

In any case, as a general rule, you should be suspicious that you are facing a phishing attempt when the email you just received exhibits the following signs:

  1. The email is addressed to you in a general way (e.g.: Dear Reader)

  2. Calls for immediate action

  3. Use abbreviated, suspicious, or misspelled links

  4. There are spelling errors in the body of the text.

  5. Asks for personal information

  6. It comes from an email that you are not familiar with

  7. Contains suspicious attachments

  8. Proposes an offer too good to be true

Remember that typically criminals impersonate banks, government entities, companies, or social media platforms. And the attempt to steal can come not only through email but also through phone calls or text messages!

No relatório da Kaspersky de 2020, a proteção contra phishing foi acionada em dispositivos de 19,73% dos utilizadores da Kaspersky em Portugal, a segunda maior percentagem na amostra, depois do Brasil. Em 2024, o CERT.PT registou 790 incidentes de phishing, cerca de 29% dos incidentes que registou nesse ano.

Ransomware: The Essentials

If you didn't know the term: ransomware is a type of malicious software that can prevent you from accessing your system or personal files, unless you pay a ransom to regain access.

This type of software can reach your computer, for example, through a phishing attempt. And it was thanks to a similar process that the Lapsus group managed to take over the Expresso newspaper's website.

- What is Ransomware?

Now that you know how the two types of cybercrime that most affect Portuguese companies operate, it's time to learn how to defend yourself.

How do I defend my company against phishing and ransomware?

When your company understands the importance of good practices in cybersecurity, it will achieve a higher level of maturity: your employees can identify phishing attempts and your company's data is less vulnerable than before. But does that mean your company is protected against any cyberattack attempt?

Far from it.

It's up to you to strengthen the castle walls; Morebiz - IT Solutions recommends that you implement it:

  • Automatic backups
  • Credentials System
  • Secure VPNs

Download our free Manual of Good Practices - Computer Security

I will explain to you what each one means (this is exactly what I advised our clients who had security issues when remote work became mandatory):

1 - Automatic backups

ou should not only centralize your company's data on a single server but also ensure that the information stored on that server is duplicated on another server. Note: the two servers should be located in different locations to safeguard against data loss in the event of a fire or serious electrical accident.

The system works simply: the first server will allow access to the company's data at any time and from anywhere. The second server will ensure that if there is an accident with the first server, the data is not lost forever. All done automatically

2 - Credentials system

Access to your company's servers should be highly restricted. This means that each employee should have personal and non-transferable access data. Prevent anyone from entering your company's network and gaining direct access to the data and documents stored on your servers!

3 - Secure VPNs

VPN is a term that can intimidate less tech-savvy entrepreneurs. But in reality, it stands for Virtual Private Network. This Virtual Private Network is used so that your remote workers can access your company's services (e.g., accessing data or downloading documents) in asecure and controlled way.

These guidelines were provided by the General Directorate of Administration and Public Employment in April of last year, in their Guide to Health and Safety at Telework in Public Administration. If you want to delve deeper, our colleagues at Integrity.pt have done a comprehensive work, which we have taken the liberty of including in this article.
