Cyber Security News has compiled a top 10 most notable cyber-attacks of 2023 list, serving as a reminder to businesses that advancements in technology, increased connectivity, and the more sophisticated tactics used by threat actors mean that cyber-attacks are evolving at a rapid pace.

Top of its list is the MOVEit Mass Attack launched by a Russian hacking group which used the MOVEit file transfer software to extort an estimated $75-100 million from 2,667 organisations. The others in the list include Cisco IOS XE attacks, the US government hacked via Microsoft 365, the Citrix Bleed attack, Okta’s customer support data breach, the Western Digital cyber-attack, and the MGM Resorts breach. The list also includes the Royal Ransomware attack over the city of Dallas, the GoAnywhere attacks, and the 3CX software supply chain attack.

Businesses should, therefore, make sure that they are well protected for 2024 from a wide range of common cyber-attack methods, including malware, phishing, distributed denial of Service (DDoS), man-in-the-Middle (MitM), and many more.
