A former core infrastructure engineer, Daniel Rhyne, from an industrial company in New Jersey, was sentenced to 32 months in prison for attacking his employer's computer network and demanding a ransom in Bitcoin. The 59-year-old Rhyne, who is from Kansas City, Missouri, was sentenced on September 28 by U.S. District Judge Michael A. Shipp in Trenton. He pleaded guilty in April this year to charges including extortion by threatening to damage a protected computer and intentionally damaging a protected computer. The prosecution did not disclose the name of the company, which is headquartered in Somerset County, New Jersey, serving clients in industries ranging from biopharmaceuticals to oil and gas.According to the FBI's criminal complaint, around 4 PM on November 25, 2023, the company's network administrator began receiving hundreds of password reset notifications for accounts, and subsequently discovered that all other domain administrator accounts had been deleted. Forty-four minutes later, employees received an email titled "Your Network Has Been Penetrated," claiming that the company's IT administrator had been locked out, backups had been deleted, and warning that unless 20 Bitcoins (approximately $750,000 at the time) were paid by December 2, an additional 40 servers would be shut down daily for 10 days. The ransom was set at 700,000 euros, to be paid in Bitcoin.Investigators traced the attack back to an unauthorized virtual machine created on the company network on November 9, 2023, with the password "TheFr0zenCrew!", which was subsequently set for the administrator account, 301 user accounts, and the email used to send the ransom note.

A 28-year-old core member of the globally renowned ransomware group Qilin has been arrested in Japan and was extradited to Germany on October 2.

Japanese police apprehended him while he was traveling to Osaka in late May this year, and he was subsequently handed over to German authorities after being deemed eligible by the Tokyo High Court. Qilin operates under a "ransomware as a service" (RaaS) model and previously claimed responsibility for a cyber attack on Japan's Asahi Group in 2025.

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.

Following the attack on the Liquid Network, Blockstream rejected the hacker's demand for a 10% ransom on the remaining approximately 598.5 bitcoins and requested the hacker to return the bitcoins. "Unauthorized acquisition of assets and refusal to return them is a criminal act, not responsible disclosure; this is by no means white hat hacking, but outright theft."Previously, after Blockstream confirmed that the vulnerability in the bridging node had been fixed, the Liquid Network attacker returned 3,400 BTC and retained approximately 598.5 BTC (worth about 47.3 million USD).

Blockstream tweeted that it will not pay a ransom for the return of the stolen Bitcoin from the Liquid Network, stating that acquiring assets without authorization and refusing to return them constitutes theft, which does not fall under responsible disclosure or white hat behavior.Blockstream stated that if the stolen funds are not returned, it will cooperate with law enforcement agencies, exchanges, service providers, and forensic experts to track, recover the assets, and identify the responsible parties through all legal means, while emphasizing that Bitcoin transactions are transparent and relevant evidence will not disappear. Blockstream is the main developer and technical provider of the Liquid Network. Liquid Network stated that "approximately 4,000 BTC were taken by white hat hackers," and the sidechain has therefore suspended operations.

Berlin's mayor, Kai Wegner, has made it clear that Berlin will not yield to extortion. The main departments affected are transportation and construction management, which were temporarily isolated from the state government's network after the incident.

According to Caixin, the Hong Kong Court of Appeal yesterday rejected the sentence reduction application of the mastermind behind the electric fraud and human trafficking, Ma Zhihao, and upheld the original sentence of 56 months in prison. During the investigation of the case, the Hong Kong police tracked the criminal funds through blockchain and cryptocurrency transaction records, identifying the key points where ransoms and criminal proceeds were received.It is reported that a victim's family paid approximately 9,527 Tether (USDT) to a cryptocurrency wallet designated by the criminals. The blockchain tracking records conclusively prove that 8,127 USDT flowed into an exchange account registered under Ma Zhihao's real name and Hong Kong ID, which was then exchanged for about 63,000 Hong Kong dollars and transferred to his personal HSBC bank account, becoming important evidence of his involvement in the crime and obtaining profits. The Court of Appeal pointed out that if it were not for the 7-year sentencing cap imposed by the District Court, the punishment faced by the defendant would be much heavier than this.

Cybersecurity company Check Point Research discovered that the StopAndProtect ransomware campaign uses nearly 2,000 compromised WordPress sites to spread malware, steal data, monitor victims, and deploy ransomware. This campaign was identified in mid-May. As of July 24, it has compromised over 6,000 unique IP addresses, including 1,852 in the United States, and 630 each in Russia and India.The compromised websites were also used to host malware, send commands, and store stolen files, screenshots, and activity logs. Attackers lure Windows users into running PowerShell commands through fake CAPTCHAs, thereby stealing credentials and cryptocurrency wallet recovery phrases, and spreading through networks and USB devices. Researchers have collected over 31,000 screenshots and more than 700 data compression packages, and believe that the attackers may have inadvertently infected themselves.

The United States, the European Union, and the United Kingdom jointly announced sanctions against a group involving state-level hacker organizations, cybercrime gangs, and their infrastructure providers. The targets are accused of causing billions of dollars in losses to global businesses, critical infrastructure, and government agencies. Among the most notable is the EU's sanction against the Russian cybercriminal Vitaly Nikolayevich Kovalev (alias "Stern").The EU has identified Stern as one of the core managers of the notorious Trickbot Group ransomware organization, which includes several high-risk ransomware variants such as Conti ransomware and Ryuk. On-chain analysis shows that wallet addresses associated with Stern have received over $300 million in ransom payments, potentially making him the "largest confirmed ransomware operator" to date. According to analysis, the $300 million only represents the profits obtained by Stern personally, and the overall illegal income of the Trickbot group may be much higher.On-chain fund flows indicate that Stern has had transactional connections with multiple ransomware ecosystems, including Ryuk, Conti, Diavol, Karakurt, Royal, and Quantum. Investigations show that Stern plays a role similar to "CEO" within the Trickbot organization, responsible for budget management, personnel recruitment, infrastructure procurement, and attack planning.
