ComicForm and SectorJ149 Hackers Deploy Formbook Malware in Eurasian Cyberattacks

сент. 22, 2025 Malware / Data Theft
Organizations in Belarus, Kazakhstan, and Russia have emerged as the target of a phishing campaign undertaken by a previously undocumented hacking group called ComicForm since at least April 2025. The activity primarily targeted industrial, financial, tourism, biotechnology, research, and trade sectors, cybersecurity company F6 said in an analysis published last week. The attack chain involves sending emails bearing subject lines like "Waiting for the signed document," "INvoice for Payment," or "Reconciliation Act for Signature," urging recipients to open an RR archive, within which there exists a Windows executable that masquerades as a PDF document (e.g., "Акт_сверки pdf 010.exe"). The messages, written in Russian or English, are sent from email addresses registered in the .ru, .by, and .kz top-level domains. The executable is an obfuscated .NET loader designed to launch a malicious DLL ("MechMatrix Pro.dll"), which subsequently...

How to Gain Control of AI Agents and Non-Human Identities

How to Gain Control of AI Agents and Non-Human Identities

сент. 22, 2025 AI Security / Cloud Security
We hear this a lot: "We've got hundreds of service accounts and AI agents running in the background. We didn't create most of them. We don't know who owns them. How are we supposed to secure them?" Every enterprise today runs on more than users. Behind the scenes, thousands of non-human identities, from service accounts to API tokens to AI agents, access systems, move data, and execute tasks around the clock. They're not new. But they're multiplying fast. And most weren't built with security in mind. Traditional identity tools assume intent, context, and ownership. Non-human identities have none of those. They don't log in and out. They don't get offboarded. And with the rise of autonomous agents, they're beginning to make their own decisions, often with broad permissions and little oversight. It's already creating new blind spots. But we're only at the beginning. In this post, we'll look at how non-human identity risk is evolving, where most organizations are still exposed, and...

Microsoft Patches Critical Entra ID Flaw Enabling Global Admin Impersonation Across Tenants

сент. 22, 2025 Cloud Security / Vulnerability
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...
DPRK Hackers Use ClickFix to Deliver BeaverTail Malware in Crypto Job Scams

DPRK Hackers Use ClickFix to Deliver BeaverTail Malware in Crypto Job Scams

сент. 21, 2025 Malware / Threat Intelligence
Threat actors with ties to the Democratic People's Republic of Korea (aka DPRK or North Korea) have been observed leveraging ClickFix-style lures to deliver a known malware called BeaverTail and InvisibleFerret. "The threat actor used ClickFix lures to target marketing and trader roles in cryptocurrency and retail sector organizations rather than targeting software development roles," GitLab Threat Intelligence researcher Oliver Smith said in a report published last week. First exposed by Palo Alto Networks in late 2023, BeaverTail and InvisibleFerret have been deployed by North Korean operatives as part of a long-running campaign dubbed Contagious Interview (aka Gwisin Gang), wherein the malware is distributed to software developers under the pretext of a job assessment. Assessed to be a subset of the umbrella group Lazarus , the cluster has been active since at least December 2022. Over the years, BeaverTail has also been propagated via bogus npm packages and f...

Researchers Uncover GPT-4-Powered MalTerminal Malware Creating Ransomware, Reverse Shell

сент. 20, 2025 Malware / Artificial Intelligence
Cybersecurity researchers have discovered what they say is the earliest example known to date of a malware that bakes in Large Language Model (LLM) capabilities. The malware has been codenamed MalTerminal by SentinelOne SentinelLABS research team. The findings were presented at the LABScon 2025 security conference. In a report examining the malicious use of LLMs, the cybersecurity company said AI models are being increasingly used by threat actors for operational support, as well as for embedding them into their tools – an emerging category called LLM-embedded malware that's exemplified by the appearance of LAMEHUG (aka PROMPTSTEAL) and PromptLock . This includes the discovery of a previously reported Windows executable called MalTerminal that uses OpenAI GPT-4 to dynamically generate ransomware code or a reverse shell. There is no evidence to suggest it was ever deployed in the wild, raising the possibility that it could also be a proof-of-concept malware or red team tool. ...
ShadowLeak Zero-Click Flaw Leaks Gmail Data via OpenAI ChatGPT Deep Research Agent

ShadowLeak Zero-Click Flaw Leaks Gmail Data via OpenAI ChatGPT Deep Research Agent

сент. 20, 2025 Artificial Intelligence / Cloud Security
Cybersecurity researchers have disclosed a zero-click flaw in OpenAI ChatGPT's Deep Research agent that could allow an attacker to leak sensitive Gmail inbox data with a single crafted email without any user action. The new class of attack has been codenamed ShadowLeak by Radware. Following responsible disclosure on June 18, 2025, the issue was addressed by OpenAI in early August. "The attack utilizes an indirect prompt injection that can be hidden in email HTML (tiny fonts, white-on-white text, layout tricks) so the user never notices the commands, but the agent still reads and obeys them," security researchers Zvika Babo, Gabi Nakibly, and Maor Uziel said . "Unlike prior research that relied on client-side image rendering to trigger the leak, this attack leaks data directly from OpenAI's cloud infrastructure, making it invisible to local or enterprise defenses." Launched by OpenAI in February 2025, Deep Research is an agentic capability built into ...

SystemBC Powers REM Proxy With 1,500 Daily VPS Victims Across 80 C2 Servers

сент. 19, 2025 Botnet / Network Security
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...

17,500 Phishing Domains Target 316 Brands Across 74 Countries in Global PhaaS Surge

сент. 19, 2025 Email Security / Social Engineering
The phishing-as-a-service (PhaaS) offerings known as Lighthouse and Lucid has been linked to more than 17,500 phishing domains targeting 316 brands from 74 countries. "Phishing-as-a-Service (PhaaS) deployments have risen significantly recently," Netcraft said in a new report. "The PhaaS operators charge a monthly fee for phishing software with pre-installed templates impersonating, in some cases, hundreds of brands from countries around the world." Lucid was first documented by Swiss cybersecurity company PRODAFT earlier this April, detailing the phishing kit's ability to send smishing messages via Apple iMessage and Rich Communication Services (RCS) for Android. The service is assessed to be the work of a Chinese-speaking threat actor known as the XinXin group (changqixinyun), which has also leveraged other phishing kits like Lighthouse and Darcula in its operations. Darcula is developed by an actor named LARVA-246 (aka X667788X0 or xxhcvv), while Light...

Russian Hackers Gamaredon and Turla Collaborate to Deploy Kazuar Backdoor in Ukraine

Russian Hackers Gamaredon and Turla Collaborate to Deploy Kazuar Backdoor in Ukraine

сент. 19, 2025 Malware / Cyber Espionage
Cybersecurity researchers have discerned evidence of two Russian hacking groups Gamaredon and Turla collaborating together to target and co-comprise Ukrainian entities. Slovak cybersecurity company ESET said it observed the Gamaredon tools PteroGraphin and PteroOdd being used to execute Turla group's Kazuar backdoor on an endpoint in Ukraine in February 2025, indicating that Turla is very likely actively collaborating with Gamaredon to gain access to specific machines in Ukraine and deliver the Kazuar backdoor.  "PteroGraphin was used to restart the Kazuar v3 backdoor, possibly after it crashed or was not launched automatically," ESET said in a report shared with The Hacker News. "Thus, PteroGraphin was probably used as a recovery method by Turla." In a separate instance in April and June 2025, ESET said it also detected the deployment of Kazuar v2 through two other Gamaredon malware families tracked as PteroOdd and PteroPaste. Both Gamaredon (aka Aqua B...

CISA Warns of Two Malware Strains Exploiting Ivanti EPMM CVE-2025-4427 and CVE-2025-4428

сент. 19, 2025 Data Breach / Vulnerability
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...

SonicWall Urges Password Resets After Cloud Backup Breach Affecting Under 5% of Customers

сент. 18, 2025 Data Breach / Network Security
SonicWall is urging customers to reset credentials after their firewall configuration backup files were exposed in a security breach impacting MySonicWall accounts. The company said it recently detected suspicious activity targeting the cloud backup service for firewalls, and that unknown threat actors accessed backup firewall preference files stored in the cloud for less than 5% of its customers. "While credentials within the files were encrypted, the files also included information that could make it easier for attackers to potentially exploit the related firewall," the company said . The network security company said it's not aware of any of these files being leaked online by the threat actors, adding it was not a ransomware event targeting its network. "Rather this was a series of brute-force attacks aimed at gaining access to the preference files stored in backup for potential further use by threat actors," it noted. It's currently not known who is...
