Volt Typhoon | Breaking Cybersecurity News | The Hacker News

The U.S. Environmental Protection Agency (EPA) said it's forming a new "Water Sector Cybersecurity Task Force" to devise methods to counter the threats faced by the water sector in the country. "In addition to considering the prevalent vulnerabilities of water systems to cyberattacks and the challenges experienced by some systems in adopting best practices, this Task Force in its deliberations would seek to build upon existing collaborative products," the EPA  said . In a letter sent to all U.S. Governors, EPA Administrator Michael Regan and National Security Advisor Jake Sullivan highlighted the need to secure water and wastewater systems (WWS) from cyber attacks that could disrupt access to clean and safe drinking water. At least two threat actors have been linked to intrusions targeting the nation's water systems, including those by an Iranian hacktivist group named  Cyber Av3ngers  as well as the China-linked  Volt Typhoon , which has targeted commu...

The U.S. government on Wednesday said the Chinese state-sponsored hacking group known as  Volt Typhoon  had been embedded into some critical infrastructure networks in the country for at least five years. Targets of the threat actor include communications, energy, transportation, and water and wastewater systems sectors in the U.S. and Guam. "Volt Typhoon's choice of targets and pattern of behavior is not consistent with traditional cyber espionage or intelligence gathering operations, and the U.S. authoring agencies assess with high confidence that Volt Typhoon actors are pre-positioning themselves on IT networks to enable lateral movement to OT assets to disrupt functions," the U.S. government  said . The idea is to pre-position themselves on IT networks by maintaining persistence and understanding the target environment over time for disruptive or destructive cyber attacks against U.S. critical infrastructure in the event of a major crisis or conflict with the coun...

IT leaders know the drill—regulators and cyber insurers demand regular network penetration testing to keep the bad guys out. But here's the thing: hackers don't wait around for compliance schedules. Most companies approach network penetration testing on a set schedule, with the most common frequency being twice a year (29%), followed by three to four times per year (23%) and once per year (20%), according to the Kaseya Cybersecurity Survey Report 2024 . Compliance-focused testing can catch vulnerabilities that exist at the exact time of testing, but it's not enough to stay ahead of attackers in a meaningful way. Why More Frequent Testing Makes Sense When companies test more often, they're not just checking a box for compliance—they're actually protecting their networks. The Kaseya survey also points out that the top drivers for network penetration testing are: Cybersecurity Control and Validation (34%) – ensuring the security controls work and vulnerabilities are minimized.

The threat actors behind the  KV-botnet  made "behavioral changes" to the malicious network as U.S. law enforcement began issuing commands to neutralize the activity. KV-botnet is the name given to a network of compromised small office and home office (SOHO) routers and firewall devices across the world, with one specific cluster acting as a covert data transfer system for other Chinese state-sponsored actors, including  Volt Typhoon  (aka Bronze Silhouette, Insidious Taurus, or Vanguard Panda). Active since at least February 2022, it was  first documented  by the Black Lotus Labs team at Lumen Technologies in mid-December 2023. The botnet is known to comprise two main sub-groups, viz. KV and JDY, with the latter principally used for scanning potential targets for reconnaissance. Late last month, the U.S. government  announced  a court-authorized disruption effort to take down the KV cluster, which is typically reserved for manual operations a...
