Ransomware is increasingly targeting home backups on NAS, cloud storage, and external drives. Here’s how these attacks work, and how to keep your family photos and documents safe.
An unknown threat actor compromised the npm account of an axios maintainer, publishing two malicious versions of the package. These versions introduced a dependency on plain-crypto-js, a newly created malicious package. Despite quick removal, axios's widespread usage led to rapid exposure. The malicious package includes a dropper that downloads and executes platform-specific second-stage payloads, functioning as remote access trojans. These payloads can execute remote shells, inject binaries, browse directories, list processes, and perform system reconnaissance. Organizations are advised to audit their environments, remove malicious artifacts, rotate exposed credentials, investigate potential compromise paths, and monitor for suspicious activity.

In case of a cyber incident, most organizations fear more of data loss (via exfiltration) than regular data encryption because they have a good backup policy in place. If exfiltration happened, it means a total loss of control of the stolen data with all the consequences (PII, CC numbers, …).
Operation DualScript is a sophisticated multi-stage malware campaign targeting cryptocurrency and financial activities. It utilizes Windows Scheduled Tasks, VBScript launchers, and PowerShell execution to maintain persistence while minimizing disk artifacts. The attack operates through two parallel chains: a web-based PowerShell loader deploying a cryptocurrency clipboard hijacker, and a secondary chain executing the RetroRAT implant in memory. RetroRAT monitors user activity, captures keystrokes, and tracks interactions with financial services to harvest sensitive information. The malware employs various anti-analysis techniques and establishes a command-and-control channel for remote access and data exfiltration. This campaign highlights the growing abuse of trusted system utilities and in-memory execution techniques to evade traditional detection mechanisms.
This is the fourth update to the TeamPCP supply chain campaign threat intelligence report,&#;x26;#;xc2;&#;x26;#;xa0;"When the Security Scanner Became the Weapon"&#;x26;#;xc2;&#;x26;#;xa0;(v3.0, March 25, 2026). Update 003 covered developments through March 28, including the first 48-hour pause in new compromises and the campaign&#;x26;#;39;s shift to monetization. This update consolidates intelligence from March 28-30, 2026 -- two days since our last update.
A lot of the information seen on DShield honeypots [1] is repeated bot traffic, especially when looking at the Cowrie [2] telnet and SSH sessions. However, how long a session lasts, how many commands are run per session and what the last commands run before a session disconnects can vary. Some of this information could help indicate whether a session is automated and if a honeypot was fingerprinted. This information can also be used to find more interesting honeypot sessions.
TeamPCP launched a sophisticated attack on the Telnyx Python SDK, publishing malicious versions 4.87.1 and 4.87.2 to PyPI. The attack represents an evolution from their previous LiteLLM campaign, incorporating WAV-based steganography, split-file code injection, and expanded platform support. The payload, activated on import, uses stealthy techniques to download and execute credential-stealing malware across Linux, macOS, and Windows systems. Key changes include the use of audio steganography to hide malicious code, improved evasion through split-file injection, and the addition of Windows support with Startup folder persistence. The attackers shifted from HTTPS to plaintext HTTP infrastructure, potentially exposing their activities to network monitoring. Organizations are advised to downgrade to the last clean version and treat affected systems as compromised.

Key Takeaways What Happened AI assistants now handle some of the most sensitive data people own. Users discuss symptoms and medical history. They ask questions about taxes, debts, and personal finances, upload PDFs, contracts, lab results, and identity-rich documents that contain names, addresses, account details, and private records. That trust depends on a simple expectation: […] The post ChatGPT Data Leakage via a Hidden Outbound Channel in the Code Execution Runtime appeared first on Check Point Research .

Threat actors are exploiting tax season with numerous campaigns leveraging tax themes to deliver malware, remote monitoring tools, fraud attempts, and credential phishing. Over a hundred campaigns have been observed in 2026, with a notable increase in remote monitoring and management (RMM) payloads. Tactics include impersonating tax agencies, claiming expired documents, and requesting tax filing support. While primarily targeting the United States, campaigns have also been observed in Canada, Australia, Switzerland, and Japan. Notable actors include TA4922, a newly designated threat group delivering malware from the Winos4.0 ecosystem, and TA2730, focusing on credential phishing for financial institutions. Business email compromise actors are also using tax form lures to steal financial and personal data. These campaigns demonstrate the ongoing exploitation of timely and topical themes by cybercriminals to deceive users.
