🔒 ADT confirmed unauthorized access to customer and prospective customer data detected on April 20, saying it terminated the intrusion and opened an investigation. The company reported that stolen information was limited to names, phone numbers, and addresses, with a small subset including dates of birth and the last four digits of SSNs or Tax IDs. ADT emphasized no payment data or customer security systems were affected. ShinyHunters claims over 10 million records were taken after a vishing attack that allegedly compromised an employee’s Okta SSO and accessed Salesforce data.

🔒 Unit 42 describes a fundamental shift in the npm threat landscape following the September 2025 Shai‑Hulud worm and subsequent 2026 incidents. Adversaries now harvest npm and GitHub tokens to persist inside CI/CD pipelines, deploy dormant multi‑stage payloads, and automatically republish backdoored packages. The report attributes a broad, coordinated campaign to TeamPCP, documents propagation via Docker Hub, GitHub Actions and VS Code extensions, and recommends mitigations such as credential rotation, egress filtering, and dependency pinning.

🔥 A custom backdoor named Firestarter has been observed persisting on Cisco Firepower and Secure Firewall devices running ASA or FTD software, surviving reboots, firmware updates, and security patches. U.S. CISA and the U.K. NCSC link the activity to a threat actor tracked as UAT-4356, which exploited CVE-2025-20333 and CVE-2025-20362. Cisco recommends reimaging and upgrading affected devices; administrators can check compromise with show kernel process | include lina_cs, and CISA published YARA rules and mitigation guidance.

🔎 Since February, Unit 42 has observed sustained operations by TGR-STA-1030 across multiple countries, with a pronounced concentration in Central and South America. The observed intrusions reuse the same tactics, techniques, and procedures previously attributed to this group, indicating continuity with prior espionage campaigns. Analysts reference The Shadow Campaigns: Uncovering Global Espionage for historical context, and advise organizations in affected regions to review detections and strengthen defensive controls.

🔒 Tyler Buchanan has pleaded guilty in a Florida court to conspiring with others to hack company computer systems and steal at least $8 million in virtual currency. He faces sentencing later this year. Buchanan is tied to the notorious Scattered Spider group, which has used SMS phishing and colleague impersonation to target employees. Security leaders are urged to reinforce defenses and train staff against social engineering.

📞 BlackFile, a financially motivated extortion group active since February 2026, is using vishing and spoofed VoIP/CNAM calls to impersonate IT support and harvest employee credentials and one-time passcodes. Palo Alto Networks' Unit 42 and RH-ISAC report attackers register devices to bypass multifactor authentication, escalate to executive accounts, and search Salesforce and SharePoint via APIs for files containing terms like 'confidential' and 'SSN'. Stolen data is moved to attacker-controlled infrastructure and published on a dark web leak site before seven-figure ransom demands are issued; victims have also faced swatting and targeted harassment. Organizations are advised to tighten call-handling policies, enforce caller identity verification, and conduct simulation-based social engineering training.

🔒 CISA and the U.K. NCSC disclosed that a federal civilian agency's Cisco Firepower device running ASA firmware was compromised in September 2025 by a persistent backdoor dubbed FIRESTARTER. The ELF bootkit alters the startup mount list and attempts to hook LINA to execute arbitrary shellcode and sustain post-patching persistence. Cisco recommends reimaging; a cold power cycle is a temporary mitigation.

🛰️ The NASA Office of Inspector General (OIG) says a Chinese national, identified in a 2024 indictment as Song Wu, posed as U.S. researchers to obtain sensitive aerospace modeling software and source code from NASA employees, universities, and private firms. The campaign ran from January 2017 through December 2021 and also targeted multiple U.S. government agencies. Song faces wire fraud and aggravated identity theft charges and remains at large.

🔒 The personal health data of more than 500,000 UK Biobank volunteers was briefly listed for sale on Chinese e-commerce platforms, prompting removal of the adverts and joint action by UK and Chinese authorities. UK Biobank says the datasets were de-identified and did not include direct identifiers such as names or NHS numbers, and there is currently no evidence the data were purchased. The organisation has suspended researcher access, restricted downloads on its cloud research platform and launched a forensic investigation into misuse by researchers at three academic institutions.

🔒Researchers uncovered 26 malicious iOS apps, dubbed FakeWallet, impersonating popular cryptocurrency wallets on the Apple App Store since at least fall 2025. The apps, available to users whose Apple accounts are set to China, redirect victims to trojanized wallet builds or phishing pages to capture recovery phrases and private keys. Kaspersky found the campaign uses typosquatting, library injection, OCR modules, and enterprise provisioning to install payloads. Apple removed many of the apps after disclosure.

📦 A Dutch journalist followed instructions on a government website to conceal a Bluetooth tracker inside a mailed postcard addressed to a naval ship, enabling observers to follow the vessel for roughly a day as it sailed from Heraklion, Crete, toward Cyprus. Navy personnel discovered the device during routine mail sorting within 24 hours of arrival and disabled it. As a result, Dutch authorities now ban electronic greeting cards from naval mail to close that screening gap.

🛡️ Zscaler ThreatLabz attributes a new campaign to Tropic Trooper that uses a trojanized SumatraPDF installer to deliver the AdaptixC2 Beacon post‑exploitation agent. Victims—primarily Chinese‑speaking individuals in Taiwan, with some targets in South Korea and Japan—are lured via military‑themed ZIP archives that show a decoy PDF while fetching encrypted shellcode. The backdoored reader launches a Xiangoop‑derived loader called TOSHIS, which stages payloads and only escalates to installing Visual Studio Code and configuring VS Code tunnels for persistent remote access on high‑value hosts.

🐛Researchers from Socket have identified malicious npm packages that execute during installation to harvest credentials and developer artifacts, then attempt worm-like propagation across ecosystems. The payload targets cloud and CI/CD tokens, SSH keys, .npmrc files, browser profiles and crypto wallets, exfiltrating data via HTTPS webhooks and ICP endpoints. It attempts to republish compromised packages using stolen npm tokens and can also generate PyPI payloads via .pth injection. The campaign leverages blockchain-hosted canisters for C2 and remains under active investigation.

🔒 A high-severity SSRF vulnerability in LMDeploy (CVE-2026-33626, CVSS 7.5) was exploited in the wild within 13 hours of disclosure. The flaw in the vision-language module's load_image() function allows fetching arbitrary URLs without validating internal addresses, enabling access to cloud metadata and internal services. Security researchers and Sysdig observed targeted port scanning, API enumeration, and out-of-band DNS callbacks, highlighting rapid weaponization of AI-infrastructure bugs.

🛡️ A malicious npm release of the Bitwarden CLI (version 2026.4.0) was briefly published after attackers compromised a GitHub Action in the project's CI/CD pipeline. The trojanized package included a loader that installs bun and executes a payload designed to harvest cloud, development, and CI credentials. Bitwarden reported no evidence of user vault access and the package was removed within roughly 1.5 hours, with compromised access revoked and remediation initiated.

🔒 The Bitwarden CLI @bitwarden/cli npm package was briefly compromised when attackers published a malicious v2026.4.0 release on April 22, 2026. The injected payload harvested developer secrets — including npm and GitHub tokens, SSH keys, and cloud credentials — and contained self‑propagation capability to infect other packages. Bitwarden confirmed only the npm distribution channel was affected, found no evidence of vault or production data access, revoked compromised access, deprecated the release, and initiated remediation; affected developers should rotate exposed credentials.

🔒 Symantec researchers observed Trigona ransomware affiliates using a custom command-line exfiltration utility, uploader_client.exe, in March to siphon high-value documents to a hardcoded server. The tool supports parallel uploads, TCP rotation after 2GB, selective file-type exclusion, and an authentication key to control access to stolen data. The shift from public utilities like Rclone appears intended to reduce detection during double-extortion operations. Symantec has published IoCs to aid defenders.

🔒 Mandiant attributes a newly documented cluster, UNC6692, with social-engineering campaigns via Microsoft Teams that coerce victims into installing malicious software and browser extensions. The actor leverages large-scale email-bombing to create urgency, then impersonates IT helpdesk staff to deliver an AutoHotkey-based installer hosted on attacker-controlled AWS S3. That installer loads the SNOW malware family — including SNOWBELT, SNOWGLAZE, and SNOWBASIN — enabling credential theft, tunneling, lateral movement, and data exfiltration.

🔐 Checkmarx's KICS Docker images and VS Code/Open VSX extensions were trojanized to harvest developer secrets. Dependency security firm Socket investigated after Docker alerted them to malicious images pushed to the official checkmarx/kics repository and found an embedded MCP addon that downloaded a credential-stealing module (mcpAddon.js). The malware targeted GitHub tokens, cloud credentials, npm tokens, SSH keys, Claude configs and environment variables, encrypting and exfiltrating them to audit.checkmarx.cx while creating public GitHub repositories to receive stolen data. Checkmarx removed the artifacts, rotated exposed credentials and advised developers to rotate secrets, pin image SHAs and rebuild from trusted sources.

🔐 Cisco Talos reports that UAT-4356 exploited FXOS n-day vulnerabilities (CVE-2025-20333 and CVE-2025-20362) to deploy a custom backdoor named FIRESTARTER on Cisco Firepower, ASA and FTD appliances. The implant injects into the LINA process, replaces a WebVPN XML handler, and executes shellcode delivered via specially crafted requests. Operators should follow Cisco advisories for detection, remediation and recommended software upgrades.
