By: Ganesan D 07 Jan 2025 Category: Cyber Threats

This year has seen a huge spike in cyber-attacks, targeting critical areas like infrastructure, healthcare, financial institutions, and even political campaigns.

These attacks show just how advanced hackers are becoming and how vulnerable many industries still are. Here’s a look at the Top 10 Cyber Attacks of 2024, breaking down their impact, scale, and what they mean on a global level.

Key Takeaways from 2024 Cybersecurity Trends

Healthcare Under Siege:

Ransomware gangs ramped up attacks on healthcare systems, exploiting their critical importance.

Geopolitical Espionage:

State-sponsored hackers, particularly from China and Russia, intensified assaults on critical infrastructure and political organizations.

Supply Chain Vulnerabilities:

High-profile incidents like the XZ Utils attack highlighted the inherent risks in software supply chains.

AI Weaponization:

Cybercriminals began harnessing generative AI tools for advanced malware creation and offensive operations.

2024's Most Notorious Cyber Incidents

1. Ransomware Chaos in Healthcare:

The Alphv/BlackCat group attacked Change Healthcare in February, crippling healthcare services across the U.S. Over 100 million individuals’ medical data were exposed, and the company paid $22 million in ransom to restore operations.

2. Cloud Breach Nightmare

Snowflake’s cloud platform suffered a breach in April due to missing multifactor authentication (MFA). Major companies like AT&T, Ticketmaster, and Santander Bank were impacted, with terabytes of sensitive data stolen by the Scattered Spider group.

3. Espionage from the East

Chinese state-backed groups led two campaigns in 2024:

Volt Typhoon targeted U.S. critical infrastructure to prepare for potential disruptions.
Salt Typhoon infiltrated telecom providers, stealing metadata and targeting political figures.

4. Software Supply Chain Attack

March’s XZ Utils backdoor attack (CVE-2024-3094) was a near-disaster. Malicious code in a common utility threatened thousands of downstream systems globally before being contained.

5. Data Broker Breach Exposed

In April, hackers compromised National Public Data’s systems, leaking 2.9 billion records. This breach exposed personal information like Social Security numbers, sold on the dark web for $3.5 million.

6. Update Gone Wrong

CrowdStrike’s faulty Falcon update in July led to a global outage, affecting 8.5 million devices. Airlines and hospitals were hit hard, causing $5.4 billion in damages for major corporations.

7. Attack on Internet Archives

Hackers exposed 31 million files from the Internet Archive in September and launched politically motivated DDoS attacks, linked to pro-Palestinian groups.

8. AI Misuse Attempts

State-sponsored groups from Russia, China, and Iran attempted to exploit OpenAI’s tools for phishing, reconnaissance, and malware creation, but OpenAI successfully thwarted these attempts.

9. Dell Customer Data Exposed

In May, Dell Technologies disclosed a breach of 49 million customer records. The attackers attempted to sell the stolen data online for $500,000.

10. Russian Espionage at Microsoft

Midnight Blizzard (APT29) infiltrated Microsoft’s corporate email systems, targeting senior executives in cybersecurity and legal roles. This campaign was part of broader espionage activities discovered in January 2024.

Lessons Learned

Cybersecurity is no longer optional. Companies must adopt advanced strategies like multi-factor authentication (MFA), continuous vulnerability scanning, and robust employee training to counter the evolving threat landscape.
