Inside a Data Breach: What Really Happens?

Data breaches have unfortunately become one of those facts of our digitized life. As cyber threats grow in sophistication, even the smallest and largest organizations can become victims of an attack that allows unauthorized parties access to sensitive information. 

But what does a data breach actually consist of? To understand that, let us go in-depth into the anatomy of a breach: its stages, consequences, and the important steps an organization needs to take to respond.

What Causes a Data Breach?

Anything that ranges from high-level hacking attempts to even simple mistakes made by employees can bring about a data breach. Some very common causes include:

Malicious Attacks

Phishing, malware, or ransomware is leveraged by cybercriminals as a standard method to gain unauthorized access to systems and data.

Human Error

Employees may unwittingly disclose sensitive information through misconfigurations, lost devices, or falling for social engineering tactics.

System Vulnerabilities

Outdated software, weak passwords, or unpatched security flaws may provide an open door for attackers.

Knowing what these triggers are is important for an organization to take appropriate and effective preventive measures that will reduce the likelihood of a breach.

How Does a Data Breach Occur?

A typical data breach follows a series of stages, often referred to as the “cyber kill chain.” This process includes:

Reconnaissance

The attackers acquire information about the target organization and look for a possible vulnerability to infiltrate it.

Initial Compromise

With this information, the hackers breach all the system’s defenses, usually through some weak point-an unsecured server or phishing email.

Privilege Escalation

The attackers, once inside, increase their privileges in the system to higher levels that would allow them to move laterally across the network.

Lateral Movement

With elevated privileges, hackers explore the network, searching for valuable data and additional systems to compromise.

Data Exfiltration

The attacker begins extracting sensitive information, often in small batches to avoid detection.

Covering Tracks

Sophisticated attackers will attempt to erase evidence of their presence, making it harder for the organization to detect and respond to the breach.

Understanding this process helps organizations better prepare for and respond to potential breaches.

What Happens Immediately After a Breach?

The period immediately after a data breach is discovered is very crucial. The organizations need to act with speed and ensure that limited damage is caused to the stakeholders. The following are the essential steps that an organization should take after the occurrence of data breach:

Containment of Breach

This involves stopping the bleeding by isolating all affected systems from further unauthorized access.
The crisis management team should be composed of representatives from the IT security, legal, and communication sectors.

Initial Assessment

Establish quickly the scope and severity of the breach, including what data was compromised and who might be affected.

Evidence Preservation

Document in detail every shred of evidence related to the breach for further analysis and possible legal proceedings.

These preparatory measures will, in turn, set the platform for a much deeper response and restoration operation.

How Should Organizations Communicate About a Breach?

Communication over the data breach is very sensitive. It calls for a tight balance between being open while taking into account the legal and strategic positions. Breach communication elements would include:

Internal Communication

Informed staff about the incident and well-briefed with standard questions/answers

Stakeholder Notification

Inform all affected parties, affiliates, and other agencies as may be required by law and in good conscience immediately.

Communications Plan

Formulate a clear-cut, single message to assure the public to regain confidence in the organization.

Good communication would lessen reputational damage and demonstrate that an organization is serious about assuming liability for the breach.

What Are The Long-Term Consequences Of A Data Breach?

A data breach has impacts reaching well beyond the initial crisis. Organizations should therefore be prepared for a variety of long-term consequences that might include:

Financial Consequences

Breach response costs, legal fees, regulatory fines, and possible class-action lawsuits can amount to millions of dollars.

Reputation Loss

A breach could result in erosion of customer confidence in the company brand, which might subsequently affect lost business and market value.

Operational Disruption

Breach recovery may be time-consuming and require resources that divert focus from regular core business operations.

Regulatory Scrutiny

A breach may trigger additional regulatory scrutiny and compliance standards that the organization is expected to follow.

Awareness of the potential long-term impacts makes a stronger case for better cybersecurity and well-planned incident response.
