New Python Backdoor Uses Tunneling Service to Steal Browser and Cloud Credentials

New Python Backdoor Uses Tunneling Service to Steal Browser and Cloud Credentials

Apr 30, 2026 Cloud Security / Threat Intelligence
Cybersecurity researchers have disclosed details of a stealthy Python-based backdoor framework called DEEP#DOOR that comes with capabilities to establish persistent access and harvest a wide range of sensitive information from compromised hosts. "The intrusion chain begins with execution of a batch script ('install_obf.bat') that disables Windows security controls, dynamically extracts an embedded Python payload ('svc.py'), and establishes persistence through multiple mechanisms including Startup folder scripts, registry Run keys, scheduled tasks, and optional WMI subscriptions," Securonix researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a report shared with The Hacker News. It's assessed that the batch script is distributed via traditional approaches like phishing. It's currently not known how widespread attacks distributing the malware are, and if any of those infections have been successful. "Based on our current a...

New Linux 'Copy Fail' Vulnerability Enables Root Access on Major Distributions

New Linux 'Copy Fail' Vulnerability Enables Root Access on Major Distributions

Apr 30, 2026 Linux / Vulnerability
Cybersecurity researchers have disclosed details of a Linux local privilege escalation (LPE) flaw that could allow an unprivileged local user to obtain root. The high-severity vulnerability tracked as CVE-2026-31431 (CVSS score: 7.8) has been codenamed Copy Fail by Xint.io and Theori. "An unprivileged local user can write four controlled bytes into the page cache of any readable file on a Linux system, and use that to gain root," the vulnerability research team at Xint.io and Theori said . At its core, the vulnerability stems from a logic flaw in the Linux kernel's cryptographic subsystem, specifically within the algif_aead module. The issue was introduced in a source code commit made in August 2017. Successful exploitation of the shortcoming could allow a simple 732-byte Python script to edit a setuid binary and obtain root on essentially all Linux distributions shipped since 2017, including Amazon Linux, RHEL, SUSE, and Ubuntu. The Python exploit involves four ...
Google Fixes CVSS 10 Gemini CLI CI RCE and Cursor Flaws Enable Code Execution

Google Fixes CVSS 10 Gemini CLI CI RCE and Cursor Flaws Enable Code Execution

Apr 30, 2026 AI Security / Vulnerability
Google has addressed a maximum severity security flaw in Gemini CLI -- the "@google/gemini-cli" npm package and the "google-github-actions/run-gemini-cli" GitHub Actions workflow -- that could have allowed attackers to execute arbitrary commands on host systems. "The vulnerability allowed an unprivileged external attacker to force their own malicious content to load as Gemini configuration," Novee Security said in a Wednesday report. "This triggered command execution directly on the host system, bypassing security before the agent’s sandbox even initialized." The shortcoming, which does not have a CVE identifier, carries a CVSS score of 10.0. It affects the following versions - @google/gemini-cli < 0.39.1 @google/gemini-cli < 0.40.0-preview.3 google-github-actions/run-gemini-cli < 0.1.22 In its advisory published last week, Google said the impact is limited to workflows using Gemini CLI in headless mode, adding that any use of...

SAP-Related npm Packages Compromised in Credential-Stealing Supply Chain Attack

Apr 29, 2026 Supply Chain Attack / Malware
Cybersecurity researchers are sounding the alarm about a new supply chain attack campaign targeting SAP-related npm Packages with credential-stealing malware. According to reports from Aikido Security , Onapsis , OX Security ,  SafeDep , Socket , StepSecurity , and Google-owned Wiz , the campaign – calling itself the Mini  Shai-Hulud – has affected the following packages associated with SAP's JavaScript and cloud application development ecosystem - mbt@1.2.48 @cap-js/db-service@2.10.1 @cap-js/postgres@2.2.2 @cap-js/sqlite@2.2.2 "The affected versions introduced new installation-time behavior that was not previously part of these packages' expected functionality," Socket said. "The compromised releases added a preinstall script that acts as a runtime bootstrapper, downloading a platform-specific Bun ZIP from GitHub Releases, extracting it, and immediately executing the extracted Bun binary." "The implementation also follows HTTP redirects wi...
New Wave of DPRK Attacks Uses AI-Inserted npm Malware, Fake Firms, and RATs

New Wave of DPRK Attacks Uses AI-Inserted npm Malware, Fake Firms, and RATs

Apr 29, 2026 Malware / Social Engineering
Cybersecurity researchers have discovered malicious code in an npm package after a malicious package as a dependency to the project by Anthropic's Claude Opus large language model (LLM). The package in question is " @validate-sdk/v2 ," which is listed on npm as a utility software development kit (SDK) for hashing, validation, encoding/decoding, and secure random generation. However, its real functionality is to plunder sensitive secrets from the compromised environment. The package, which shows signs of being vibe-coded using generative artificial intelligence (AI), was first uploaded to the repository in October 2025. The malware campaign has been codenamed PromptMink by ReversingLabs, which linked the activity as part of a broader campaign mounted by the North Korean threat actor known as Famous Chollima (aka Shifty Corsair), which is behind the long-running Contagious Interview campaign and the fraudulent IT Worker scam . "The new malware campaign [...] inv...
Webinar: How to Automate Exposure Validation to Match the Speed of AI Attacks

Webinar: How to Automate Exposure Validation to Match the Speed of AI Attacks

Apr 29, 2026 Artificial Intelligence / Exposure Validation
In February 2026, researchers uncovered a shift that completely changed the game: threat actors are now using custom AI setups to automate attacks directly into the kill chain. We aren't just talking about AI writing better phishing emails anymore. We’re talking about autonomous agents mapping Active Directory and seizing Domain Admin credentials in minutes. The problem? Most defensive workflows still look like this: your CTI team finds a threat, they pass it to the Red Team to test, and eventually, the results reach the Blue Team for patching. This process is full of friction, silos, and delays. The reality is simple: You cannot fight an AI adversary moving at machine speed when your defense moves at the speed of a calendar invite. To bridge this gap, we’re hosting a technical deep dive with the team at Picus Security to unveil a new defensive paradigm: Autonomous Exposure Validation .

What to Look for in an Exposure Management Platform (And What Most of Them Get Wrong)

What to Look for in an Exposure Management Platform (And What Most of Them Get Wrong)

Apr 29, 2026 Exposure Management / Security Operations
Every security team has a version of the same story. The quarter ends with hundreds of vulnerabilities closed. The dashboards are bursting with green. Then someone in a leadership meeting asks: "So, are we actually safer now?" Crickets. The room goes quiet because an honest answer requires context – which is something that patch counts and CVSS scores were never designed to provide. Exposure management was created to provide this context - to bridge the gap between remediation efforts and actual risk reduction. The market has responded with a flood of platforms claiming to deliver it.  Yet the question security leaders are asking is: which exposure management platform actually does provide it? In this article, I’ll break down the four dominant approaches to exposure management, explain what each one can and can't deliver, and lay out five evaluation criteria that help you separate platforms built to reduce risk to your unique business and environment from platforms ...

LiteLLM CVE-2026-42208 SQL Injection Exploited within 36 Hours of Disclosure

LiteLLM CVE-2026-42208 SQL Injection Exploited within 36 Hours of Disclosure

Apr 29, 2026 Vulnerability / Cloud Security
In yet another instance of threat actors quickly jumping on the exploitation bandwagon, a newly disclosed critical security flaw in BerriAI's LiteLLM Python package has come under active exploitation in the wild within 36 hours of the bug becoming public knowledge. The vulnerability, tracked as CVE-2026-42208 (CVSS score: 9.3), is an SQL injection that could be exploited to modify the underlying LiteLLM proxy database. "A database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter," LiteLLM maintainers said in an alert last week. "An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example, POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorized access to the proxy and the c...
