Russia-Linked Hackers Use Microsoft 365 Device Code Phishing for Account Takeovers

Russia-Linked Hackers Use Microsoft 365 Device Code Phishing for Account Takeovers

Dec 19, 2025 Cybersecurity / Cloud Security
A suspected Russia-aligned group has been attributed to a phishing campaign that employs device code authentication workflows to steal victims' Microsoft 365 credentials and conduct account takeover attacks. The activity, ongoing since September 2025, is being tracked by Proofpoint under the moniker UNK_AcademicFlare . The attacks involve using compromised email addresses belonging to government and military organizations to strike entities within government, think tanks, higher education, and transportation sectors in the U.S. and Europe. "Typically, these compromised email addresses are used to conduct benign outreach and rapport building related to the targets' area of expertise to ultimately arrange a fictitious meeting or interview," the enterprise security company said . As part of these efforts, the adversary claims to share a link to a document that includes questions or topics for the email recipient to review before the meeting. The URL points to a Clo...
Cracked Software and YouTube Videos Spread CountLoader and GachiLoader Malware

Cracked Software and YouTube Videos Spread CountLoader and GachiLoader Malware

Dec 19, 2025 Endpoint Security / Threat Intelligence
Cybersecurity researchers have disclosed details of a new campaign that has used cracked software distribution sites as a distribution vector for a new version of a modular and stealthy loader known as CountLoader. The campaign "uses CountLoader as the initial tool in a multistage attack for access, evasion, and delivery of additional malware families," Cyderes Howler Cell Threat Intelligence team said in an analysis. CountLoader was previously documented by both Fortinet and Silent Push, detailing the loader's ability to push payloads like Cobalt Strike, AdaptixC2, PureHVNC RAT, Amatera Stealer, and PureMiner. The loader has been detected in the wild since at least June 2025. The latest attack chain begins when unsuspecting users attempt to download cracked versions of legitimate software like Microsoft Word, which causes them to be redirected to a MediaFire link hosting a malicious ZIP archive, which contains an encrypted ZIP file and a Microsoft Word document wi...
WatchGuard Warns of Active Exploitation of Critical Fireware OS VPN Vulnerability

WatchGuard Warns of Active Exploitation of Critical Fireware OS VPN Vulnerability

Dec 19, 2025 Vulnerability / Network Security
WatchGuard has released fixes to address a critical security flaw in Fireware OS that it said has been exploited in real-world attacks. Tracked as CVE-2025-14733 (CVSS score: 9.3), the vulnerability has been described as a case of out-of-bounds write affecting the iked process that could allow a remote unauthenticated attacker to execute arbitrary code. "This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer," the company said in a Thursday advisory. "If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured." The vulnerability impacts the following versions of Fireware OS - 2025.1 - Fixed in 2025.1.4 12.x - Fixed in 12.11.6 1...

Nigeria Arrests RaccoonO365 Phishing Developer Linked to Microsoft 365 Attacks

Nigeria Arrests RaccoonO365 Phishing Developer Linked to Microsoft 365 Attacks

Dec 19, 2025 Cybercrime / Law Enforcement
Authorities in Nigeria have announced the arrest of three "high-profile internet fraud suspects" who are alleged to have been involved in phishing attacks targeting major corporations, including the main developer behind the RaccoonO365 phishing-as-a-service (PhaaS) scheme. The Nigeria Police Force National Cybercrime Centre (NPF–NCCC) said investigations conducted in collaboration with Microsoft and the Federal Bureau of Investigation (FBI) led to the identification of Okitipi Samuel, also known as Moses Felix, as the principal suspect and developer of the phishing infrastructure. "Investigations reveal that he operated a Telegram channel through which phishing links were sold in exchange for cryptocurrency and hosted fraudulent login portals on Cloudflare using stolen or fraudulently obtained email credentials," the NPF said in a post shared on social media. In addition, laptops, mobile devices, and other digital equipment linked to the operation have been se...
New UEFI Flaw Enables Early-Boot DMA Attacks on ASRock, ASUS, GIGABYTE, MSI Motherboards

New UEFI Flaw Enables Early-Boot DMA Attacks on ASRock, ASUS, GIGABYTE, MSI Motherboards

Dec 19, 2025 Firmware Security / Vulnerability
Certain motherboard models from vendors like ASRock, ASUSTeK Computer, GIGABYTE, and MSI are affected by a security vulnerability that leaves them susceptible to early-boot direct memory access ( DMA ) attacks across architectures that implement a Unified Extensible Firmware Interface ( UEFI ) and input–output memory management unit ( IOMMU ). UEFI and IOMMU are designed to enforce a security foundation and prevent peripherals from performing unauthorized memory accesses, effectively ensuring that DMA-capable devices can manipulate or inspect system memory before the operating system is loaded. The vulnerability, discovered by Nick Peterson and Mohamed Al-Sharifi of Riot Games in certain UEFI implementations, has to do with a discrepancy in the DMA protection status. While the firmware indicates that DMA protection is active, it fails to configure and enable the IOMMU during the critical boot phase. "This gap allows a malicious DMA-capable Peripheral Component Interconnect E...
China-Aligned Threat Group Uses Windows Group Policy to Deploy Espionage Malware

China-Aligned Threat Group Uses Windows Group Policy to Deploy Espionage Malware

Dec 18, 2025 Malware / Cloud Security
A previously undocumented China-aligned threat cluster dubbed LongNosedGoblin has been attributed to a series of cyber attacks targeting governmental entities in Southeast Asia and Japan. The end goal of these attacks is cyber espionage, Slovak cybersecurity company ESET said in a report published today. The threat activity cluster has been assessed to be active since at least September 2023. "LongNosedGoblin uses Group Policy to deploy malware across the compromised network, and cloud services (e.g., Microsoft OneDrive and Google Drive) as command and control (C&C) servers," security researchers Anton Cherepanov and Peter Strýček said . Group Policy is a mechanism for managing settings and permissions on Windows machines. According to Microsoft, Group Policy can be used to define configurations for groups of users and client computers, as well as manage server computers. The attacks are characterized by the use of a varied custom toolset that mainly consists of C#...
