Chinese threat actors have been using the Quad7 botnet in password-spray attacks, posing a significant cybersecurity threat. Reports indicate that Chinese hackers have deeply penetrated the U.S. telecommunications infrastructure, potentially allowing them to monitor millions of mobile-phone users on the networks of at least three major U.S. carriers. They have also infiltrated the private wiretapping and surveillance system built for the exclusive use of U.S. federal law enforcement agencies. This breach has raised concerns about the vulnerability of American telecom systems to Chinese government surveillance. Additionally, the City of Columbus, Ohio, has confirmed that the Rhysida ransomware gang stole the personal data of 500,000 residents, including sensitive information such as Social Security numbers and bank account details, during a July attack. The city had initially downplayed the severity of the hack, but recent disclosures have highlighted the extensive impact of the breach.
