A critical token validation failure in Microsoft Entra ID (previously Azure Active Directory) could have allowed attackers to impersonate any user, including Global Administrators, across any tenant. The vulnerability, tracked as CVE-2025-55241 , has been assigned the maximum CVSS score of 10.0. It has been described by Microsoft as a privilege escalation flaw in Azure Entra. There is no indication that the issue was exploited in the wild. It has been addressed by the Windows maker as of July 17, 2025, requiring no customer action. Security researcher Dirk-jan Mollema, who discovered and reported the shortcoming on July 14, said the shortcoming made it possible to compromise every Entra ID tenant in the world, with the likely exception of national cloud deployments . The problem stems from a combination of two components: the use of service-to-service (S2S) actor tokens issued by the Access Control Service (ACS) and a fatal flaw in the legacy Azure AD Graph API (graph.windows.n...

A proxy network known as REM Proxy is powered by malware known as SystemBC , offering about 80% of the botnet to its users, according to new findings from the Black Lotus Labs team at Lumen Technologies. "REM Proxy is a sizeable network, which also markets a pool of 20,000 Mikrotik routers and a variety of open proxies it finds freely available online," the company said in a report shared with The Hacker News. "This service has been a favorite for several actors such as those behind TransferLoader , which has ties to the Morpheus ransomware group." SystemBC is a C-based malware that turns infected computers into SOCKS5 proxies, allowing infected hosts to communicate with a command-and-control (C2) server and download additional payloads. First documented by Proofpoint in 2019, it's capable of targeting both Windows and Linux systems . In a report earlier this January, ANY.RUN revealed that the Linux variant of SystemBC proxy implant is potentially desi...

Fortra has disclosed details of a critical security flaw in GoAnywhere Managed File Transfer (MFT) software that could result in the execution of arbitrary commands. The vulnerability, tracked as CVE-2025-10035 , carries a CVSS score of 10.0, indicating maximum severity. "A deserialization vulnerability in the License Servlet of Fortra's GoAnywhere MFT allows an actor with a validly forged license response signature to deserialize an arbitrary actor-controlled object, possibly leading to command injection," Fortra said in an advisory released Thursday. The company also noted that successful exploitation of the vulnerability is dependent on the system being publicly accessible over the internet. Users are advised to update to the patched release – version 7.8.4, or the Sustain Release 7.6.3 – to safeguard against potential threats. If immediate patching is not possible, it's advisable to ensure that access to the GoAnywhere Admin Console is not open to the public...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday released details of two sets of malware that were discovered in an unnamed organization's network following the exploitation of security flaws in Ivanti Endpoint Manager Mobile (EPMM). "Each set contains loaders for malicious listeners that enable cyber threat actors to run arbitrary code on the compromised server," CISA said in an alert. The vulnerabilities that were exploited in the attack include CVE-2025-4427 and CVE-2025-4428 , both of which have been abused as zero-days prior to them being addressed by Ivanti in May 2025. While CVE-2025-4427 concerns an authentication bypass that allows attackers to access protected resources, CVE-2025-4428 enables remote code execution. As a result, the two flaws could be chained to execute arbitrary code on a vulnerable device without authentication. According to CISA, the threat actors gained access to server running EPMM by combing the two vulner...

Google on Wednesday released security updates for the Chrome web browser to address four vulnerabilities, including one that it said has been exploited in the wild. The zero-day vulnerability in question is CVE-2025-10585 , which has been described as a type confusion issue in the V8 JavaScript and WebAssembly engine. Type confusion vulnerabilities can have severe consequences as they can be weaponized by bad actors to trigger unexpected software behavior, resulting in the execution of arbitrary code and program crashes. Google's Threat Analysis Group (TAG) has been credited with discovering and reporting the flaw on September 16, 2025. As is typically the case, the company did not share any additional specifics about how the vulnerability is being abused in real-world attacks, by whom, or the scale of such efforts. This is done to prevent other threat actors from exploiting the issue before users can apply a fix. "Google is aware that an exploit for CVE-2025-10585 exis...

Cybersecurity researchers have disclosed multiple critical security vulnerabilities in Chaos Mesh that, if successfully exploited, could lead to cluster takeover in Kubernetes environments. "Attackers need only minimal in-cluster network access to exploit these vulnerabilities, execute the platform's fault injections (such as shutting down pods or disrupting network communications), and perform further malicious actions, including stealing privileged service account tokens," JFrog said in a report shared with The Hacker News. Chaos Mesh is an open-source cloud-native Chaos Engineering platform that offers various types of fault simulation and simulates various abnormalities that might occur during the software development lifecycle.

A team of academics from ETH Zürich and Google has discovered a new variant of a RowHammer attack targeting Double Data Rate 5 (DDR5) memory chips from South Korean semiconductor vendor SK Hynix. The RowHammer attack variant, codenamed Phoenix ( CVE-2025-6202 , CVSS score: 7.1), is capable of bypassing sophisticated protection mechanisms put in place to resist the attack. "We have proven that reliably triggering RowHammer bit flips on DDR5 devices from SK Hynix is possible on a larger scale," the Computer Security Group (COMSEC) at ETH Zürich said. "We also proved that on-die ECC does not stop RowHammer, and RowHammer end-to-end attacks are still possible with DDR5." RowHammer refers to a hardware vulnerability where repeated access of a row of memory in a DRAM chip can trigger bit flips in adjacent rows, resulting in data corruption. This can be subsequently weaponized by bad actors to gain unauthorized access to data, escalate privileges, or even cause a...

The attacks involve sending an HTTP request to the "/apriso/WebServices/FlexNetOperationsService.sv...

A security weakness has been disclosed in the artificial intelligence (AI)-powered code editor Cursor that could trigger code execution when a maliciously crafted repository is opened using the program. The issue stems from the fact that an out-of-the-box security setting is disabled by default, opening the door for attackers to run arbitrary code on users' computers with their privileges. "Cursor ships with Workspace Trust disabled by default, so VS Code-style tasks configured with runOptions.runOn: 'folderOpen' auto-execute the moment a developer browses a project," Oasis Security said in an analysis. "A malicious .vscode/tasks.json turns a casual 'open folder' into silent code execution in the user's context." Cursor is an AI-powered fork of Visual Studio Code, which supports a feature called Workspace Trust to allow developers to safely browse and edit code regardless of where it came from or who wrote it. With this option disab...

Threat actors affiliated with the Akira ransomware group have continued to target SonicWall devices for initial access. Cybersecurity firm Rapid7 said it observed a spike in intrusions involving SonicWall appliances over the past month, particularly following reports about renewed Akira ransomware activity since late July 2025.
