Trivy Supply Chain Attack Triggers Self-Spreading CanisterWorm Across 47 npm Packages

Mar 21, 2026Malware / Threat Intelligence

The threat actors behind the supply chain attack targeting the popular Trivy scanner are suspected to be conducting follow-on attacks that have led to the compromise of a large number of npm packages with a previously undocumented self-propagating worm dubbed CanisterWorm . The name is a reference to the fact that the malware uses an ICP canister , which refers to tamperproof smart contracts on the Internet Computer blockchain, as a dead drop resolver . The development marks the first publicly documented abuse of an ICP canister for the explicit purpose of fetching the command-and-control (C2) server, Aikido Security researcher Charlie Eriksen said . The list of affected packages is below - 28 packages in the @EmilGroup scope 16 packages in the @opengov scope @teale.io/eslint-config @airtm/uuid-base32 @pypestream/floating-ui-dom The development comes within a day after threat actors leveraged a compromised credential to publish malicious trivy, trivy-action, and setup-tri...

Trivy Security Scanner GitHub Actions Breached, 75 Tags Hijacked to Steal CI/CD Secrets

Mar 20, 2026DevSecOps / Cloud Security

Trivy, a popular open-source vulnerability scanner maintained by Aqua Security, was compromised a second time within the span of a month to deliver malware that stole sensitive CI/CD secrets. The latest incident impacted GitHub Actions " aquasecurity/trivy-action " and " aquasecurity/setup-trivy ," which are used to scan Docker container images for vulnerabilities and set up GitHub Actions workflow with a specific version of the scanner, respectively. "We identified that an attacker force-pushed 75 out of 76 version tags in the aquasecurity/trivy-action repository, the official GitHub Action for running Trivy vulnerability scans in CI/CD pipelines," Socket security researcher Philipp Burckhardt said . "These tags were modified to serve a malicious payload, effectively turning trusted version references into a distribution mechanism for an infostealer." The payload executes within GitHub Actions runners and aims to extract valuable developer s...

Critical Langflow Flaw CVE-2026-33017 Triggers Attacks within 20 Hours of Disclosure

Mar 20, 2026Vulnerability / Artificial Intelligence

A critical security flaw impacting Langflow has come under active exploitation within 20 hours of public disclosure, highlighting the speed at which threat actors weaponize newly published vulnerabilities. The security defect, tracked as CVE-2026-33017 (CVSS score: 9.3), is a case of missing authentication combined with code injection that could result in remote code execution. "The POST /api/v1/build_public_tmp/{flow_id}/flow endpoint allows building public flows without requiring authentication," according to Langflow's advisory for the flaw. "When the optional data parameter is supplied, the endpoint uses attacker-controlled flow data (containing arbitrary Python code in node definitions) instead of the stored flow data from the database. This code is passed to exec() with zero sandboxing, resulting in unauthenticated remote code execution." The vulnerability affects all versions of the open-source artificial intelligence (AI) platform prior to and inc...

Google Adds 24-Hour Wait for Unverified App Sideloading to Reduce Malware and Scams

Mar 20, 2026Data Privacy / Mobile Security

Google on Thursday announced a new "advanced flow" for Android sideloading that requires a mandatory 24-hour wait period to install apps from unverified developers in an attempt to balance openness with safety. The new changes come against the backdrop of a developer verification mandate the tech giant announced last year that requires all Android apps to be registered by verified developers to be installed on certified Android devices. The move, it added, was done to flag bad actors faster and prevent them from distributing malware. This also includes potential scenarios where cybercriminals trick unsuspecting users who sideload such apps into granting them elevated privileges that make it possible to turn off Play Protect, the anti-malware feature built into all Google-certified Android devices. However, the mandatory registration requirements have been met with criticism from over 50 app developers and marketplaces, including F-Droid, Brave, The Electronic Fronti...

The Importance of Behavioral Analytics in AI-Enabled Cyber Attacks

Mar 20, 2026Artificial Intelligence / Data Protection

Artificial Intelligence (AI) is changing how individuals and organizations conduct many activities, including how cybercriminals carry out phishing attacks and iterate on malware. Now, cybercriminals are using AI to generate personalized phishing emails, deepfakes and malware that evade traditional detection by impersonating normal user activity and bypassing legacy security models. As a result, rule-based models alone are often insufficient for identity security against AI-enabled threats. Behavioral analytics must evolve beyond monitoring suspicious activity patterns over time into dynamic, identity-based risk modeling capable of identifying inconsistencies in real time. Common risks introduced by AI-enabled attacks AI-enabled cyber attacks introduce very different security risks compared to traditional cyber threats. By relying on automation and mimicking legitimate behavior, AI allows cybercriminals to scale their attacks while reducing obvious signals to remain undetected. AI-...

Magento PolyShell Flaw Enables Unauthenticated Uploads, RCE and Account Takeover

Mar 20, 2026Web Security / Vulnerability

Sansec is warning of a critical security flaw in Magento's REST API that could allow unauthenticated attackers to upload arbitrary executables and achieve code execution and account takeover. The vulnerability has been codenamed PolyShell by Sansec owing to the fact that the attack hinges on disguising malicious code as an image. There is no evidence that the shortcoming has been exploited in the wild. The unrestricted file upload flaw affects all Magento Open Source and Adobe Commerce versions up to 2.4.9-alpha2. The Dutch security firm said the problem stems from the fact that Magento's REST API accepts file uploads as part of the custom options for the cart item. "When a product option has type 'file,' Magento processes an embedded file_info object containing base64-encoded file data, a MIME type, and a filename," it said . "The file is written to pub/media/custom_options/quote/ on the server." Depending on the web server configuration, the ...

"For example, if you're using an older version of iOS and were to click a malicious link or visit a compromised website, the data on your iPhone might be at risk of being stolen," Apple said in a support document. "We thoroughly investigated these issues as they were found and released software updates as quickly as possible for the most recent operating system versions to address vulnerabilities and disrupt such attacks."

Speagle Malware Hijacks Cobra DocGuard to Steal Data via Compromised Servers

Mar 19, 2026Cyber Espionage / Threat Intelligence

Cybersecurity researchers have flagged a new malware dubbed Speagle that hijacks the functionality and infrastructure of a legitimate program called Cobra DocGuard. "Speagle is designed to surreptitiously harvest sensitive information from infected computers and transmit it to a Cobra DocGuard server that has been compromised by the attackers, masking the data exfiltration process as legitimate communications between client and server," Symantec and Carbon Black researchers said in a report published today. Cobra DocGuard is a document security and encryption platform developed by EsafeNet. The abuse of this software in real-world attacks has been publicly recorded twice to date. In January 2023, ESET documented an intrusion where a gambling company in Hong Kong was compromised in September 2022 via a malicious update pushed by the software. Later that August, Symantec highlighted the activity of a new threat cluster codenamed Carderbee, which was found using a trojan...
