JDY botnet scans SOHO/IoT devices globally to map services and targets, especially US military networks. Lumen’s Black Lotus Labs reported the resurgence of the JDY botnet, a covert reconnaissance network tied to Chinese state-sponsored hacking groups including Volt Typhoon. The network was first spotted in late 2023 as a cluster inside KV-botnet. The U.S. government […]

Cybersecurity researchers have warned of a "resurgence and expansion" of JDY, a covert network associated with China-nexus state-sponsored threat actors

The Russian state-sponsored hacking group known as Turla has transformed its custom backdoor Kazuar into a modular peer-to-peer (P2P) botnet that's engineered for stealth and persistent access to compromised hosts

Kazuar, a sophisticated malware family attributed to the Russian state actor Secret Blizzard, has been under constant development for years and continues to evolve in support of espionage-focused operations. Over time, Kazuar has expanded from a relatively traditional backdoor into a highly modular peer-to-peer (P2P) botnet ecosystem designed to enable persistent, covert access to target environments. The post Kazuar: Anatomy of a nation-state botnet appeared first on Microsoft Security Blog.

Persistent Attack Grants Remote SSH Access via ExploitSomeone - possibly nation-state hackers - appears to be constructing a botnet from thousands of Asus routers in hacking that survives a firmware patch and reboots. Nearly 9,000 routers have been compromised and the number is growing, say researchers.

An elusive, sophisticated cybercriminal group has used known and zero-day vulnerabilities to compromise more than 20,000 SOHO routers and other IoT devices so far, and then puts them up for sale on a residential proxy marketplace for state-sponsored cyber-espionage actors and others to use.

The Chinese state-sponsored hacking group Volt Typhoon has begun to rebuild its "KV-Botnet" malware botnet after it was disrupted by law enforcement in January, according to researchers from SecurityScorecard. [...]

Chinese Botnet Targets US Critical Infrastructure and TaiwanA Chinese state-sponsored botnet called Raptor Train has infected more than 260,000 IoT and office network devices to target critical infrastructure globally. The hackers used zero-days and known vulnerabilities to compromise more than 20 different types of devices to expand their botnet.

Cybersecurity researchers have uncovered a never-before-seen botnet comprising an army of small office/home office (SOHO) and IoT devices that are likely operated by a Chinese nation-state threat actor called Flax Typhoon (aka Ethereal Panda or RedJuliett)

Volume of Poorly Secured, Legacy IoT That Can Be Turned Against Us Keeps GrowingThe FBI announcing that it has forcibly removed "KV Botnet" Chinese nation-state malware from "hundreds" of poorly secured SOHO routers across America highlights the risk posed by the growing volume of outdated IoT devices. The FBI's fix is temporary, and we need a more permanent solution.

US government agencies took down the botnet of Chinese APT Volt Typhoon, used to target critical infrastructure for nation-state espionage

The U.S. government on Wednesday said it took steps to neutralize a botnet comprising hundreds of U.S.-based small office and home office (SOHO) routers hijacked by a China-linked state-sponsored threat actor called Volt Typhoon and blunt the impact posed by the hacking campaign

The Chinese state-sponsored APT has compromised as many as 30% of Cisco legacy routers on a SOHO botnet that multiple threat groups use.

The Chinese state-sponsored APT hacking group known as Volt Typhoon (Bronze Silhouette) has been linked to a sophisticated botnet named 'KV-botnet' since at least 2022 to attack SOHO routers in high-value targets. [...]
