Cybersecurity Weekly Report The Evolution of the Threat Landscape

Not much cybercrime made headlines from 21 to 27 March 2026; however, it should be noted that the period was not without action. This past week represents a shift that is much more critical than the previous week’s events. Cyberattacks are becoming more covert, thoughtful, and integrated into daily life. The increased investment in cybersecurity professional training demonstrates that traditional defense mechanisms alone cannot provide sufficient defense against the more advanced nature of today’s cyber threats. Attackers are now taking longer-term access to systems, using more covert methods of manipulation, and planning for data extraction over a longer period of time.

A third-party data breach associated with a major digital platform and the disruption from ransomware affecting a municipal system in the U.S. are both examples of how attackers are innovating their attack models. Now that organizations are focusing on where they are the largest or most obvious target, attackers are looking for indirect access to systems, including through vendors, integrations, and blind spots that do not raise alarms when accessed. This represents a noticeable shift from direct attack to subtle incursions.

Why Are Supply Chain and Indirect Attacks Increasing?

The increasing attack vector reliance on supply chains and third-party services was emphasized this week. Instead of targeting an organization’s highly secured core systems, attackers are now moving towards exploiting external service providers and associated platforms that generally have less stringent security mechanisms. Many recent incidents illustrate that attackers lack access to the primary infrastructure of an organization, but gained access to the data of that same organization through its partner ecosystem or third-party supply chains.

This represents a significant shift for modern organisations given how connected the modern business world is. Each time an organization connects to another organisation via an API, outsourced service, or other similar integrations, additional risks are introduced. Due to pre-defined trust in many connections, an attacker can utilize an exploit for the first time without it being apparent that an attack has been executed.

This creates difficulty for anyone trying to investigate an attack against an entity as they will have no indicators of an attack occurring. Attackers are using this inherent trust in these connections as a means to compromise data and gain persistent access for extended periods of time.

What Do Recent Incidents Reveal About Critical Infrastructure Security?

A ransomware attack on a municipal computer system this week revealed current weaknesses in our city’s infrastructure of public sector systems. While it didn’t rise to the level of a major crisis, the incident caused temporary closures of a number of important services that demonstrate just how quickly and dramatically restricted access to essential services can have an impact on their operation.

Many public sector systems are still dependent on outdated technologies that do not have the capacity for comprehensive management and monitoring which therefore creates an opportunity for an attacker to take advantage of those weaknesses without requiring any sophisticated technical skills to do so. While the goal of some attacks may be purely to steal money, others are simply intended as a means of causing disruption, testing response capabilities, or identifying gaps across an entire system.

Why Is Human Behavior Still a Major Entry Point?

This week’s major theme has been criminals continuing to use human actions as their primary method of attack. Cybercriminals will continue to use human actions as their primary method of attack. Criminals will use human actions as their primary mode of attack using attackers designing attacks that look like something users do every day rather than attackers using only technical weaknesses but rather making use of psychological impact, urgency, and trusting nature of users.

The tactics that they are using to accomplish this are as follows

• Repeated authentication requests that are designed to wear down the user’s patience and drive them to respond.

• Phishing emails generated with unknown technology that look like very realistic phishing emails that sound very similar to those sent to trusted email addresses.

• Communicating with the victim’s company using an internal or trusted source.

What makes these attacks successful is their ability to hide among normal daily activities of the users being attacked. Victims unknowingly allow access or allow unauthorized transactions because they think they are complying with a valid solicitation when responding. Because of this, these types of attacks are extremely difficult to detect, and they also shift a portion of the responsibility for security from systems to the individual user.

Are Identity-Based Attacks Becoming the Standard?

This week’s threat landscape continues to see identity-based attacks leading the way. Attackers have shifted from focusing solely on gaining access to systems; they now use various means to gain access to systems, including the use of legitimate credentials to log into systems of compromised accounts or the use of session hijacking to take advantage of valid, active sessions.

Once within an organization’s systems, attackers will frequently act in a controlled and measured manner (without triggering any alerts) by not acting quickly or drastically changing their actions.

Common patterns of identity-based attacks are as follows:

1. Gradual access over time to systems using credentials to log in from compromised accounts

2. Session hijacking used in lieu of password theft to access a system from a valid, active session

3. Slowly moving laterally across multiple connected environments

Since the behavior of an attacker aligns closely with the normal behavior of users, many traditional security controls and mechanisms may not recognize the attacker’s activity as a malicious act. Thus, there is an actual need for deeper behavioral analysis and continuous monitoring over time.

Are APIs and SaaS Ecosystems Creating Hidden Risks?

While APIs and SaaS solutions will continue to be a critical part of the way that businesses operate in this digital age, they are also increasingly becoming areas of risk. This week’s briefing shows that attackers are now starting to interact with these systems in unintended fashion instead of directly exploiting vulnerabilities.

For many systems, the problems come not from the systems themselves being broken, but from them being misused by attackers who take more data than they were supposed to and/or use too many permissions while being able to evade detection. Most SaaS systems contain either legacy integrations or non-active integrations that continue to be in place, but not actively managed.

These methods of exploitation exist as “hidden gap” vulnerabilities, and therefore make it easier for attackers to exploit these types of systems undetected, increasing the need for improved visibility and access control to all connected systems.

Why Are Attackers Choosing to Stay Invisible?

This week, the second major takeaway was how malicious attackers are continuing to favour low-noise and persistent attacks. Rather than attempting to have an immediate impact on their victims, malicious hackers seem to favour going undetected for extended periods. This allows them more time and opportunity to study their targets, learn how users within that organization behave and maximize the value of being able to access their target’s systems.

There are three common behaviors that malicious attackers exhibit while conducting low-noise persistent attacks:

• Collecting data slowly over time versus conducting mass data exfiltration
• Operating a system continuously without any apparent interruptions
• Creating user behaviour patterns that closely mimic what a legitimate user would be doing

This method of operation creates the perception of a false sense of security for organizations because, although their systems are operating normally, there may still be threats that continue to exist and are evolving behind the scenes.

How Is Cybercrime Becoming More Structured?

Cybercrime has transitioned from being a collection of isolated events to an interconnected and organized system of crime. Over the last week, various groups have been found to be involved at multiple points along the attack lifecycle (gaining access, exploiting access, monetizing access).

The increased level of collaboration increases the efficiencies and decreases the risks of an attack; however, it makes it more difficult for organizations to protect themselves, as many organizations will face not just one criminal group but a group of specialized criminal groups working in concert with one another.

What Makes Cybersecurity An Essential Skill By 2026

With the rapid development of new technologies, the demand for highly-skilled individuals in cyber security has grown exponentially. Today’s organizations not only want their employees to have theoretical knowledge about how cyber attacks occur, but also want them to have practical experience responding to these attacks in real life.

Many modern courses are adapting by placing more emphasis on hands-on training providing

learners with practical skills including:

• Threat Detection and Analysis
• Monitoring User Behaviour
• Incident Response and Recovery

At the Boston Institute of Analytics, there has been a movement towards developing learners’ capabilities through practical hands-on training to prepare them for the real world. The goal of the Boston Institute of Analytics is to help learners transition from theory-based concepts to real-life application within continually changing environments.

A major goal of Boston Institute of Analytics is to provide learners with the tools necessary to move beyond just theoretical concepts and into practical application in a continually changing world.

What are Some Methods Companies are Adapting to These New Environments?

Most companies are beginning to make the switch from single-layered or single-dimensional security systems to a more comprehensive approach. Organizations are now combining prevention, detection, and response to achieve this objective.

Some of the approaches taken by organizations to combine their efforts include:

• Monitoring users across multiple systems
• Tracking the behavior of API and Integration systems
• Observing endpoint and device activity
• Establishing multi-layered security frameworks

With more visibility and greater ability to respond, organizations will be able to lessen the amount of time it takes from when they have been breached until they have detected the breach.

Conclusion: What Can We Learn from This Week?

The way cybercrime has evolved from being noisy and disruptive to now relying on trust, behavior, and complexity in their systems to achieve their goals is what we can take away from the week’s events. Organizations must adapt to this new approach to cybersecurity in order to protect against potential attacks as well as to learn how these incidents will unfold over a longer period; therefore, organizations need to have visibility, agility/versatility/ability (or similar), and continuous learning at the forefront of their modern cybersecurity programs.

As we have seen in the past few weeks, those entering the cybersecurity field must also consider their training in relation to other aspects of life, cybersecurity course fees, and how good of a fit job-wise and financially they are for them. Having the right program to develop real-world skills will be an important part of being able to remain relevant within the ever-changing world of cybersecurity.
