What is a DoS Attack? Types, Exploitations and Security Tips

In the space of 5 years, the number of Denial of Service (DoS) attacks has almost doubled. The result is the paralysis of tens of millions of web platforms and the loss of thousands or even millions of euros by victim organisations.

Companies such as Amazon and GitHub have already been affected by this type of attack. One of the best-known attacks is MIRAI, which used a botnet of nearly 100,000 hijacked machines to make Dyn’s services unavailable in 2016.

Black Box Penetration Testing: Objective, Methodology and Use Cases

During a penetration test, we generally consider 3 test conditions: black, grey or white box.

These test conditions correspond to the levels of information provided to the pentesters in order to carry out a pentest on a specific target. While a white box pentest will consist of providing as much information as possible, during a black box penetration test, the pentesters will have no data on the test target.

Antivirus and EDR Bypass Techniques

Antivirus, anti-malware and EDR are tools commonly used to prevent attacks.

However, these solutions can be bypassed. In this article, we take a closer look at the various antivirus and EDR bypass techniques that can be implemented in a loader: a program whose aim is to execute a malicious payload on a machine by bypassing the various protections in place.

What is Smishing?

Smishing (SMS phishing): How to Identify Attacks and Protect Yourself?

You will no doubt be familiar with phishing, which consists of sending malicious emails to encourage people to perform sensitive actions, such as entering their credentials on a fake authentication page.

Smishing is very similar, except that the attacker does not send emails, but text messages, hence the name smishing. Essentially, smishing is nothing more and nothing less than SMS phishing.

Penetration Testing: Methodology, Scope and Types of Pentests

With cybersecurity risks on the rise, it is becoming more and more obvious to carry out a penetration test (pentest) to reassure customers, partners and investors.

Moreover, for companies involved in a certification process (ISO 27001, SOC2, HDS, PCI-DSS, etc.), a penetration test is an imperative. And for others, it is an essential prerequisite for satisfying the pentesting report requests of their customers and prospects.

API Penetration Testing: Objective, Methodology, Black Box, Grey Box and White Box Tests

APIs are prime targets for attackers because of their exposure and critical nature, particularly in terms of handling sensitive data. To minimise the risk of security breaches, it is essential to implement robust security measures, understand the types of attack and assess their potential impact.

There are several ways of assessing the security of an API. In this article, we present the “offensive” approach, which we believe to be the most effective: API penetration testing (or API pentesting). We detail the principles and objectives, as well as use cases for black box, grey box and white box pentesting.
