Cybersecurity round-up 2024- The biggest news from 2024 and what to expect in 2025

Cybersecurity round-up 2024- The biggest news from 2024 and what to expect in 2025

This year has been pivotal for cybersecurity, marked by large-scale data breaches, record-breaking ransomware attacks, and growing challenges for security professionals. As 2024 comes to a close, it’s essential to reflect on some of the major incidents that defined the year and discuss what lies ahead in 2025 for the ever-evolving cybersecurity landscape.

2024’s most notable cybersecurity incidents

CrowdStrike outage causing global disruption

In July, a software update from the cloud security firm CrowdStrike caused widespread outages, disabling 8.5 million Windows devices worldwide. The incident led to significant disruptions across critical sectors, including emergency services, airports, and law enforcement.

The error behind this disruption highlights the importance of thorough testing and quality assurance in updates for security tools. It also serves as a stark reminder of how even trusted cybersecurity vendors can inadvertently cause massive operational disruptions.

Midnight Blizzard’s attack on Microsoft

The Russian state-backed group Midnight Blizzard dominated headlines early in the year with its calculated attack on Microsoft. Utilizing a password spray attack, the group exploited a legacy test tenant account lacking multi-factor authentication, granting access to sensitive corporate emails and internal systems. Later in the year, the group continued its assault with targeted spear-phishing campaigns, emphasizing the importance of robust authentication measures and proactive threat detection.

Record ransomware payouts

Global ransomware payments exceeded $1 billion for the first time in 2023, and 2024 saw this trend continue unabated. Sophisticated “big game hunting” tactics, targeting large organizations with demands exceeding $1 million, were a significant driver of this escalation. The rising use of artificial intelligence further lowered barriers to entry, enabling a surge in the number of active ransomware groups.

The world’s largest compilation of passwords leaked

In July, a hacking forum posted nearly 10 billion unique plaintext passwords, the largest-ever compilation of its kind. Dubbed "rockyou2024.txt," the file contained credentials from numerous past breaches. This incident underscored the urgency for stronger password policies, multi-factor authentication, and user education to prevent credential-based attacks.

The largest health data breach in U.S. history

In October, the private health information of over 100 million individuals was exposed in a ransomware attack targeting Change Healthcare. The breach, attributed to the ALPHV ransomware group, disrupted critical healthcare services and resulted in a $22 million ransom payout. This incident highlighted the vulnerability of the healthcare sector and the dire need for robust cybersecurity measures to protect sensitive patient data.

What to expect in 2025

The lessons from 2024 provide a roadmap for understanding and mitigating future threats. Here are the key trends and expectations for the year ahead:

The growing role of artificial intelligence

AI’s dual-edged impact on cybersecurity will become even more pronounced in 2025. On the defensive side, AI-driven tools will enhance threat detection, vulnerability management, and incident response. However, attackers are also leveraging AI to automate phishing, craft sophisticated malware, and identify new vulnerabilities. Organizations must invest in AI-powered solutions while continuously monitoring for AI-driven threats.

Increased focus on cloud security

As cloud adoption continues to rise, so do the associated security risks. Misconfigured cloud environments and inadequate access controls remain primary concerns. Expect to see greater emphasis on secure cloud architectures, real-time monitoring, and compliance frameworks tailored for cloud-based operations.

Supply chain security as a priority

High-profile breaches in 2024 have highlighted vulnerabilities in the software supply chain. In 2025, organizations are likely to adopt stricter vendor vetting processes, continuous monitoring of third-party integrations, and adherence to supply chain security standards like the Software Bill of Materials (SBOM).

Addressing the cybersecurity talent gap

With 90% of organizations reporting skills shortages and increasing burnout among cybersecurity professionals, addressing this talent gap will be critical in 2025. Initiatives such as upskilling programs, cross-training within IT teams, and the adoption of automated tools to reduce workload will play an essential role in alleviating this crisis.

Proactive approach to ransomware

Given the record payouts and rising number of attacks, combating ransomware will remain a top priority. Organizations will increasingly adopt zero-trust architectures, maintain comprehensive data backups, and prioritize incident response planning to minimize potential disruptions and financial losses.

Global cybersecurity legislation and cooperation

2025 is likely to bring tighter regulations and international cooperation in cybersecurity. Governments worldwide are expected to implement stricter laws governing data privacy, incident reporting, and ransomware payments. Enhanced collaboration between nations will also play a crucial role in dismantling organized cybercrime operations.

Wrapping up

The cybersecurity landscape of 2024 has been defined by unprecedented incidents, from massive data breaches to operational disruptions caused by ransomware. These events underscore the importance of adopting a proactive and layered approach to cybersecurity.

As we step into 2025, organizations must embrace emerging technologies, prioritize workforce development, and focus on collaborative efforts to combat the evolving threat landscape.

The new year promises advancements in cybersecurity strategies and tools, but with them comes greater responsibility. It’s a call to action for organizations to remain vigilant, adaptive, and prepared for whatever challenges lie ahead.

 

2024 was full of cybersecurity lessons. Excited to see how AI and proactive strategies shape 2025—staying ahead is key!
