Cybersecurity news covers everything related to protecting computers, networks, programs and data from unauthorized access, attacks or damage. Staying informed on this evolving field helps professionals develop strategies to combat threats and protect their clients’ data.
Several high-profile cyberattacks in 2025 highlighted how sensitive customer information can become compromised and businesses’ ability to operate as usual. The hack of 23andMe, for example, compromised the personal data of more than 14 million people; while a breach of Mr. Cooper Group’s systems led to the theft of account information on nearly all current and former customers.
These incidents often have a ripple effect, with businesses and governments across the globe affected by disruptions to payment processing, security alerts, data breaches and other vulnerabilities. This underscores the need for a coordinated international strategy and increased collaboration among public and private sector organizations to address growing cyberattack threats.
In October, Boeing, one of the world’s largest aerospace and defense contractors, was hit by a ransomware attack involving a flaw in Citrix software known as Citrix Bleed. The flaw was exploited by the LockBit ransomware strain, which ultimately leaked 43 gigabytes of Boeing data when the company refused to pay a demanded ransom.
In addition, a new self-replicating worm called ACR Stealer is ramping up attacks against unpatched Cisco IOS XE devices in Australia. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the threat to its Known Exploited Vulnerabilities Catalog, with attackers exploiting the flaw in the wild to gain root privileges on susceptible systems.
