In 2024, cyber threats reached new levels of severity, with some of the most damaging attacks in history. These attacks targeted governments, organizations, and individuals, highlighting the growing risks in the digital world. The scale and impact of these breaches made it clear that cybersecurity resilience is no longer optional but essential. Many businesses and governments felt the effects, from data loss to financial damage. The following are seven major cyber events from 2024, their consequences, and key lessons for improving cybersecurity. Let’s dive into the critical takeaways for organizations.

| November 2024 | US Telecom Breach | Chinese hackers (Salt Typhoon) | Accessed sensitive call data and wiretapping systems | Still under assessment |
| October 2024 | Ukrainian Recruitment Disruption | Russian hackers (UNC5812) | Phishing campaign disrupted military recruitment | Undisclosed |
| July 2024 | CrowdStrike Global IT Outage | Faulty update | IT disruptions in major industries worldwide | $5.4 billion |
| June 2024 | Indonesia National Data Center Ransomware | Unknown hackers | Disrupted 282 public services | National crisis and data loss |
| May 2024 | UK Ministry of Defense Data Breach | Chinese hackers | Payroll records of 270,000 military personnel exposed | Raised security concerns |
| March 2024 | Israeli Nuclear Facility Network Breach | Iranian hackers | Leaked documents from nuclear facility | Future attack risks |
| February 2024 | French Citizen Data Breach | Unknown hackers | Exposed data of 33 million citizens | Significant reputational damage |
1. Chinese Hackers Breach U.S. Telecom Providers
Date: November 2024
Bad Actor: Chinese hackers (Salt Typhoon)
Impact: Compromised sensitive call data, wiretapping systems, and private communications
Details
In November 2024, a very sophisticated attack by the group known as the Salt Typhoon hackers was executed on at least eight U.S. telecom providers. The hacking operation used exploits in telecom networks to obtain sensitive information without permission. This sensitive information included call records and court-ordered wiretapping systems. This incident leaked private communication from high-profile individuals, causing a huge scare over national security threats. The attack highlighted weaknesses in the critical infrastructure, specifically in the case of state-sponsored actors.
Lesson Learned
Organizations conducting critical infrastructure operations need to pay attention to:
- Multi Layered security deployment.
- Periodic network security audit.
- Immediate detection and response to unauthorized activity.
2. Russian Hackers Target Ukrainian Draft-Age Men
Date: October 2024
Bad Actor: Russian hackers (UNC5812)
Impact: Phishing attack has halted the recruitment process while the hackers made off with people’s personal details
Details
UNC5812 – a Russian hacking group, is behind this phishing campaign against the men of the Ukrainian draft age. They employed the Telegram channel and malicious application which was disguised as tools capable of monitoring recruiters. Since they were trusted tools, their login credentials were stolen along with the malware using them to track locations and record conversations on the telephone. The hacking activity crippled the military recruitment program when the country needed soldiers most. This theft of sensitive information for use in propaganda attacks added fuel to the fire and further heightened the conflict in that region.
Lesson Learned
Phishing attacks remain one of the primary means through which attackers operate. Organizations and governments must:
- Educate their employees and public about phishing awareness.
- Implement endpoint detection and response tools.
- Use safety-featured communications tools that do feature adequate verification steps.
3. CrowdStrike Software Update Causes Global IT Outage
Date: July 2024
Bad Actor: CrowdStrike (malware software update)
Impact: Shutdowns in dozens of sectors, $5.4 billion
Details
In July 2024, a worldwide IT shutdown was caused on devices to the tune of 8.5 million, following a bad software update by cybersecurity firm CrowdStrike. The most recurring cause of system crashes would then be the BSOD, commonly known as the “blue screen of death.” The attack crippled airlines, public transportation systems, hospitals, and financial centers. The impact was economic with loss estimated above $5.4 billion making this one of the costliest cybersecurity-related cases in the same year.
Lesson Learned
Industry giants do not have exclusivity over flaws. Organizations have to:
- Test updates in isolation in controlled conditions before they release them
- Implement roll back of failed updates
- Have clear, honest communication for all stakeholders concerned
4. Indonesia’s National Data Center Hit by Ransomware
Date: June 2024
Bad Actor: Unknown hackers
Impact: Disruption of public services and critical data loss
Details
Indonesia’s Temporary National Data Center was paralyzed in June 2024 after the attack by the Brain Cipher malware ransomware. The systems, including immigration and student registration portals, were paralyzed, while operations at airports also came to a standstill. Hackers initially demanded an $8 million ransom, but the government refused to pay. The attackers eventually released a decryption key, though significant data loss had already occurred, sparking national outrage and forcing the resignation of senior officials.
Lesson Learned
Ransomware incidents reinforce the need for:
- Regular backups stored offline.
- Continuous employee training to mitigate phishing risks.
- Strong incident response plans to handle such crises effectively.
5. Chinese Hackers Breach the UK Ministry of Defense
Date: May 2024
Bad Actor: Chinese hackers
Impact: This hack exposed 270,000 military personnel payroll data
Details
A third party contractor Shared Services Connected Ltd (SSCL) was compromised wherein hackers exploited the vulnerabilities that existed in this company’s computers and gained access to Britain’s Ministry of Defense. Now the sensitive payroll record of active or retired personnel- containing personal home addresses-were stolen, in the process generating a grave nation security issue. This breach, left unchecked for months, revealed significant flaws in both the contractor’s and the government’s detection and response practices.
Lesson Learned
The hack underscores the need for:
- Third-party partners’ cybersecurity posture assessment.
- Zero-trust networks used to isolate access.
- Privileged access monitoring systems that are continuous
6. Iranian Hackers Compromise Israeli Nuclear Facility Network
Date: March 2024
Attacker: Iranian hackers
Impact: Exhilarated documents; operational systems safe
Details
In March 2024, hackers from Iran had targeted the Shimon Peres Negev Nuclear Research Center in Israel. Though they hacked into and released thousands of confidential documents, it did not access the operational systems. The breach escalates cyber warfare between Iran and Israel. However, the leaked documents were not of high sensibility, which may be utilized in phishing or social engineering later.
Lesson Learned
The entities that have high sensitivity are expected to
- Use segmented networks in order to segmentally separate the vital systems.
- Update and patch the software applications in order to fix the vulnerabilities
- Stage red team exercises to mimic the adverse persistent threat APT breaches
7. Data Breach Affects 33 Million French Citizens
Date: February 2024
Bad Actor: Anonymous hackers
Impact: Compromised sensitive private data of millions
Details
A huge data attack made public private information about 33 million French citizens who rely on two French payment processors, Viamedis and Almerys. That included social security numbers, marital status, and birth dates. The incident was tracked down to a phishing attack where, due to the mistake through human error, a few security holes in the medical portal had been exploited. According to allegations, the hacking included access to banking details and no medical report data was retrieved.
Lesson Learned
Health care has to shore up defenses via:
- Strengthening access controls on portals with sensitive data.
- Conducting regular penetration testing to uncover weaknesses.
- Training employees to recognize and avoid phishing scams.
