Hackers targeted three Iranian steel companies, forcing the country’s state-owned plant to halt production. China stated the United States stole 97 billion pieces of global internet data and 124 billion pieces of telephone data in June, specifically https://newsblock.today/the-number-of-blockchain-cyberattacks-is-growing/ blaming the National Security Agency ‘s Office of Tailored Access Operations . Hackers targeted Lithuania’s state-owned energy provider in a DDoS attack. Killnet, which Lithuanian officials link to Russia, claimed responsibility for the attack.
- Both intensive simulations and real-time experiments clearly show that our proposed collaborative learning-based intrusion detection framework can achieve an accuracy of up to 97.7% in detecting attacks.
- With solid investments in cyber security infrastructure, Estonia has developed extensive expertise in this area, becoming one of the most recognized and valued international cyber security experts.
- Keep reading to learn all about one of the most devastating crypto cyberattacks, as well as common cyberattacks used by cybercriminals.
- The report suggests a multi-layered security protocol to decentralize risk — exactly what blockchain can provide.

With the internet shrinking the world into a global village, more and more people are joining social media. More social apps are being launched with each dawn as conversational commerce gains popularity. Most social media platform users protect the services and their data with weak, unreliable passwords. The current fast-paced advancement in technology also offers an incubating https://newsblock.today/ effect to cyber-attacks to continue becoming more sophisticated and executable. With the rolling out of the game-changing fifth-generation networks that offer ten times faster download speeds, this will inevitably create more opportunities for hackers. Faster speeds will increase the chances of more devices being hacked and the execution of larger cyber-attacks.
Monitor enterprise blockchain infrastructure
As illustrated, they revolve around knowledge-based remediation ; possession-based remediation ; and biometric-based remediation . Normally, hackers penetrate the central administration of a device and automatically gain full control of the devices and systems. By decentralising such device authority systems, blockchain ensures such attacks are harder to execute . In this case, blockchain can be used to secure such overall systems or devices by decentralising their administration. The approach will give the capabilities of the device to make security decisions on their own.
This intertwining of blockchain and cybersecurity is still an evolving approach. Not all research ideas on digital identities, decentralized storage, securing edge devices, and smart contracts align with business needs. Without careful consideration, implementation can become impractical or even impossible. Here are some hurdles that organizations may encounter when considering blockchain as part of their cybersecurity strategy. In order to destroy or corrupt a blockchain, a hacker would have to destroy the data stored on every user’s computer in the global network.
What is Cryptocurrency and Does it Affect Cybersecurity?
Based on this finding, it can be said here that there is a need for research studies exploring solutions to these wide ranges of cybersecurity challenges reported in BCT in several research papers. After Estonia’s experience with the 2007 cyber attacks, scalable blockchain technology was developed to ensure integrity of data stored in government repositories and to protect its data against insider threats. Estonia became host to the NATO Cooperative Cyber Defence Centre of Excellence and the European IT agency. Coinjoin is an example of a simple protocol that works by mixing one or more initial amounts through mulitiple transactions which each continually split the inputs and outputs of each transaction throughout a pool of wallets. Changing amounts may or may not repetedly touch the same wallet address. The resulting final amount, redistributed and possibly reconsolidated either to the original or differnet addresses , cannot currently be traced back in a way that legally proves ownership of the funds.
A series of DDoS attacks targeted a high-stakes Minecraft tournament and ended up impacting Andorra Telecom, the country’s only internet service provider. An Iranian-linked group conducted espionage and other malicious cyber operations against a range of private companies and local and federal governments. The websites of the Ukrainian Cabinet of Ministers and Ministries of Foreign Affairs, Infrastructure, and Education were disrupted in the days before Russian troops invaded Ukraine. Wiper malware was also used to penetrate the networks of one Ukrainian financial institution and two government contractors. An attack on a satellite broadband service run by the American company Viasat disrupted internet services across Europe, including Ukrainian military communications at the start of the Russian invasion. The attackers hacked satellite modems belonging to thousands of Europeans to disrupt the company’s service.
What role does blockchain play in cyberattacks and cybersecurity?
Blockchain technology is a distributed and decentralised ledger system that can record transactions between multiple computers. Blockchain started as the technology behind bitcoin but has popularly grown into a promising mitigation technology for cybersecurity. It is quite a tough and challenging time for businesses that operate on digital network platforms.
