• Trend Research has identified multiple IP address ranges in Russia that are being used for cybercrime activities aligned with North Korea. These activities are associated with a cluster of campaigns related to the Void Dokkaebi intrusion set, also known as Famous Chollima.
• The Russian IP address ranges, which are concealed by a large anonymization network that uses commercial VPN services, proxy servers, and numerous VPS servers with RDP, are assigned to two companies in Khasan and Khabarovsk. Khasan is a mile from the North Korea-Russia border, and Khabarovsk is known for its economic and cultural ties with North Korea.
• Trend Research assesses that North Korea deployed IT workers who connect back to their home country through two IP addresses in the Russian IP ranges and two IP addresses in North Korea. Trend Micro’s telemetry strongly suggests these DPRK aligned IT workers work from China, Russia and Pakistan, among others.
• Based on Trend Research’s assessment, North Korea-aligned actors use the Russian IP ranges to connect to dozens of VPS servers over RDP, then perform tasks like interacting on job recruitment sites and accessing cryptocurrency-related services. Some servers involved in their brute-force activity to crack cryptocurrency wallet passwords fall within one of the Russian IP ranges.
• Instructional videos have also been found with what it looks like non-native English text, detailing how to set up a Beavertail malware command-and-control server and how to crack cryptocurrency wallet passwords. This makes it plausible that North Korea is also working with foreign conspirators.
• IT professionals in Ukraine, US, and Germany have been targeted in these campaigns by fictitious companies that lure them into fraudulent job interviews. Trend Research assesses that the primary focus of Void Dokkaebi is to steal cryptocurrency from software professionals interested in cryptocurrency, Web3, and blockchain technologies.

Exploited vulnerabilities have turned up in Ivanti products 16 times since 2024. That’s more than any other vendor in the network edge device space.

A Moscow-based disinformation network named “Pravda” — the Russian word for "truth" — is pursuing an ambitious strategy by deliberately infiltrating the retrieved data of artificial intelligence chatbots, publishing false claims and propaganda for the purpose of affecting the responses of AI models on topics in the news rather than by targeting human readers, NewsGuard has confirmed. By flooding search results and web crawlers with pro-Kremlin falsehoods, the network is distorting how large language models process and present news and information. The result: Massive amounts of Russian propaganda — 3,600,000 articles in 2024 — are now incorporated in the outputs of Western AI systems, infecting their responses with false claims and propaganda.

In September of 2024 while on a customer assigment I encountered the “Network Configuration Operators” group, a so called builtin group of Active Directory (default). As I had never heard of or encountered this group membership before, it sprung to eye immediately. Initially I tried to look up if it had any security implications, like its more known colleagues DNS Admins and Backup Operators, but to no avail. Surpisingly little came up about the group but I couldn’t help myself from probing further. This led me down the rabbithole of Registry Database access control lists and possibilities of weaponization, culminating with the discovery of CVE-2025-21293. Before we move along to the body of work, I have to give out a special thanks to Clément Labro, who initially did the heavy lifting of finding a way to weaponize performancecounters. (This will hopefully make more sense by the end of the article) and my colleagues at ReTest Security ApS, who have provided me with knowledge in the field and the oppertunity to put it to use.

In the last few days, many Tor relay operators - mainly hosting relay nodes on providers like Hetzner - began receiving abuse notices.
All the abuses reported many failed SSH login attempts - part of a brute force attack - coming from their Tor relays.

Tor relays normally only transport traffic between a guard and an exit node of the Tor network, and per-se should not perform any SSH connections to internet-facing hosts, let alone performing SSH brute force attacks.

• Trend Micro researchers observed an attacker exploiting the Atlassian Confluence vulnerability CVE-2023-22527 to achieve remote code execution for cryptomining via the Titan Network.
• The malicious actor used public IP lookup services and various system commands to gather details about the compromised machine.
• The attack involved downloading and executing multiple shell scripts to install Titan binaries and connect to the Titan Network with the attacker’s identity.
• The malicious actor connects compromised machines to the Cassini Testnet, which allows them to participate in the delegated proof of stake system for reward tokens.

• Check Point Research identified a network of GitHub accounts (Stargazers Ghost Network) that distribute malware or malicious links via phishing repositories. The network consists of multiple accounts that distribute malicious links and malware and perform other actions such as starring, forking, and subscribing to malicious repositories to make them appear legitimate.
• This network is a highly sophisticated operation that acts as a Distribution as a Service (DaaS). It allows threat actors to share malicious links or malware for distribution through highly victim-oriented phishing repositories.
• Check Point Research is tracking the threat group behind this service as Stargazer Goblin. The group provides, operates, and maintains the Stargazers Ghost Network and distributes malware and links via their GitHub Ghost accounts.
• The network distributed all sorts of malware families, including Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine.
• Our latest calculations suggest that more than 3,000 active Ghost accounts are part of the network. Based on core GitHub Ghost accounts, we believe that the network began development or testing on a smaller scale for the first time around August 2022.
• Check Point Research discovered an advertiser in Dark-Web forums that provides the exact GitHub operation. The first advertisement was published on July 8, 2023, from an account created the previous day.
• Based on the monitored campaigns from mid-May to mid-June 2024, we estimate that Stargazer Goblin earned approximately $8,000. However, we believe that this amount is only a small fraction of what the actor made during that period. The total amount during the operations’ lifespan is estimated to be approximately $100,000.
• Stargazers Ghost Network appears to be only one part of the grand picture, with other Ghost accounts operating on different platforms, constructing an even bigger Distribution as a Service universe.

Following a recent and highly disruptive cyberattack on telecom carrier Orange España the cybersecurity community needs to rethink its approach to safeguarding the digital identity of staff involved in network engineering and IT infrastructure management. Orange España is the second-largest mobile operator in Spain. In early January, an attacker going by the alias ‘Snow’ hijacked Orange España’s RIPE Network Coordination Centre (NCC) account. RIPE is Europe’s regional Internet registry. After this initial breach, Snow sabotaged the telecommunications firm’s border gateway protocol (BGP) and resource public key infrastructure (RPKI) configurations.

Chinese threat actors exploited a new zero-day vulnerability in Barracuda's Email Security Gateway (ESG) appliances.

A Lockbit ransomware attack against German hospital network Katholische Hospitalvereinigung Ostwestfalen caused service disruptions.

Discord will switch to temporary file links for all users by the end of the year to block attackers from using its CDN (content delivery network) for hosting and pushing malware.

Apple's "Find My" location network can be abused by malicious actors to stealthily transmit sensitive information captured by keyloggers installed in keyboards.

The Find My network and application is designed to help users locate lost or misplaced Apple devices, including iPhones, iPads, Macs, Apple Watches, AirPods, and Apple Tags.

The service relies on GPS and Bluetooth data crowd-sourced from millions of Apple devices worldwide to find devices reported as lost or stolen, even if those are offline.

olish intelligence services are investigating a hacking attack on the country's railways, Polish media say.

Hackers broke into railway frequencies to disrupt traffic in the north-west of the country overnight, the Polish Press Agency (PAP) reported on Saturday.

The signals were interspersed with recording of Russia's national anthem and a speech by President Vladimir Putin, the report says.

“Russia used sophisticated malware to steal sensitive information from our allies, laundering it through a network of infected computers in the United States in a cynical attempt to conceal their crimes.  Meeting the challenge of cyberespionage requires creativity and a willingness to use all lawful means to protect our nation and our allies,” stated United States Attorney Peace.  “The court-authorized remote search and remediation announced today demonstrates my Office and our partners’ commitment to using all of the tools at our disposal to protect the American people.”

A majority of 5G network operators experienced up to six cyber incidents in the past year. Defenses are especially lacking for ransomware and phishing attacks.
