🔒 Dutch healthcare software vendor ChipSoft has confirmed a ransomware incident that forced it to take its website and patient-facing digital services offline. The provider of the HiX EHR platform warned of "possible unauthorized access" and advised customers to disconnect affected systems while it investigates. The national healthcare CERT, Z-CERT, is coordinating response efforts with ChipSoft and impacted hospitals.

🔍 Cisco Talos attributes a previously undocumented cluster, UAT-10362, to targeted spear‑phishing against Taiwanese NGOs and suspected universities, deploying a new Lua‑based stager named LucidRook. The actor uses RAR/7‑Zip lures and a dropper called LucidPawn, relying on repeated DLL side‑loading to execute payloads. LucidRook embeds an Lua 5.4.8 interpreter and Rust libraries to fetch and run encrypted Lua bytecode, while some variants use a reconnaissance DLL, LucidKnight, to profile targets before staging further activity.

🔒 Smart Slider 3 Pro update infrastructure was hijacked to push a malicious 3.5.1.35 release to WordPress and Joomla sites. The tampered update preserved normal slider functionality while installing multiple backdoors, creating a hidden administrator account, and exfiltrating credentials. The vendor urges immediate upgrade to 3.5.1.36 (or restoring to 3.5.1.34 or earlier) and advises treating affected sites as fully compromised.

🔒 Microsoft Incident Response researchers detail a Storm-2755 campaign that used malvertising and SEO poisoning to phish Canadian users and capture OAuth tokens and credentials via adversary-in-the-middle (AiTM) proxying. The actor replayed tokens (notably using the Axios/1.7.9 user-agent) to hijack authenticated sessions and bypass non-phishing-resistant MFA. Compromised accounts were used to search for payroll and HR data, create hidden inbox rules, and in some cases directly modify Workday payment information, resulting in at least one confirmed payroll diversion. Microsoft urges immediate token revocation, removal of malicious inbox rules, and adoption of phishing-resistant MFA and device-based conditional access.

🔐 eSentire's Threat Response Unit identified a previously undocumented remote access trojan, STX RAT, after an attempted deployment in a financial services environment in late February 2026. The malware uses multi-stage, script-based delivery and in-memory execution to evade detection, leveraging XXTEA encryption, Zlib compression and reflective PowerShell loaders. It delays credential theft until instructed by an encrypted C2 channel and implements registry autoruns and COM hijacking for persistence. Organizations should strengthen endpoint protections and limit exposure to script-based attack vectors.

🔒 Bitcoin Depot detected unauthorized access to parts of its corporate IT environment on March 23, which allowed attackers to use compromised credentials tied to digital asset settlement accounts. Threat actors transferred 50.903 Bitcoin (approximately $3.66m) out of company-controlled wallets before the activity was blocked. The company says customer-facing platforms and customer data were not affected, and operations have not been materially disrupted. External cybersecurity specialists and law enforcement are assisting the ongoing investigation.

🛡️ Researchers at Jamf Threat Labs report a ClickFix campaign that opens Script Editor via the applescript:// URL scheme, preloading a malicious script with a single browser click. This bypasses Terminal paste protections introduced in macOS Tahoe 26.4 and removes a major user decision point. The lightweight script decodes a hidden URL, uses curl to retrieve a payload, and launches a new Atomic Stealer variant. Script Editor behavior can vary by macOS version; recent builds may prompt to save before execution.

🛡️ Jamf Threat Labs has identified a macOS malware campaign delivering the Atomic Stealer (AMOS) infostealer/backdoor using a ClickFix social engineering technique that now leverages Script Editor instead of Terminal. Attackers display fake Apple guidance in a browser window to convince users to paste and run malicious commands, bypassing Terminal paste-scanning warnings added in the macOS 26.4 update. Network defenders are advised to restrict clipboard and run-dialog use, limit execution of untrusted binaries, and block suspicious adverts and sites.

🎟️ Scammers are exploiting BTS's ARIRANG world tour pre-sales by cloning official ticket pages for multiple countries, creating at least 10 fraudulent domains observed in early April. These lookalike sites replicate the purchase flow and pressure fans into instant payments — in Brazil many victims are urged to pay via PIX, sending funds to mule accounts that are difficult to recover. To avoid fraud, fans should use only the official tour page, verify domains, confirm country-specific sales formats, and contact banks immediately if scammed. Enable banking alerts and use security software that blocks phishing sites.

🔒 A spear-phishing campaign targeting Middle Eastern civil society and journalists has been linked to the South Asian threat actor Bitter, according to Access Now and mobile-security firm Lookout. Active from 2023 through 2025, the operation used Android spyware tracked as ProSpy and deceptive staging sites to deliver malicious APKs and harvest credentials. Attackers attempted Apple and Google account takeovers and could exfiltrate files, messages, contacts, geolocation and remotely enable microphones and cameras.

🔎 Access Now, Lookout, and SMEX report a coordinated hack-for-hire campaign that targeted journalists, activists, and officials across the MENA region from 2023–2025. The operation used spear-phishing, OAuth consent-based pages, and messaging-platform lures to harvest credentials and two-factor codes. Observed domains impersonated Apple, Signal, Telegram, and Android services, and infrastructure overlaps link activity to a cluster known as Bitter. One Apple account was compromised while other intrusion attempts were blocked.

🚆 Eurail says attackers stole personal information for over 300,000 customers after an unauthorized transfer of files from its network on December 26, 2025. The company disclosed the incident publicly in February and notified affected individuals by letter on March 27, reporting that records contained names, passport numbers and other sensitive identifiers. A sample of the stolen data was posted on Telegram and put up for sale on the dark web; Eurail advises customers to update Rail Planner passwords, reset reused passwords elsewhere, monitor bank accounts, and watch for phishing and suspicious transactions.

🔒 Google Threat Intelligence Group warns that UNC6783, a financially motivated cluster possibly tied to the 'Raccoon' persona, is targeting business process outsourcers (BPOs) and large enterprises via live chat social engineering. The campaign directs employees to spoofed Okta login pages hosted on Zendesk-like domains such as [.]zendesk-support[.]com and uses a phishing kit that steals clipboard contents to bypass MFA and enroll attacker devices for persistence. GTIG also observed fake security updates delivering remote access malware and the use of Proton Mail to deliver ransom notes. Organizations should deploy phishing-resistant MFA like FIDO2 keys, monitor live chat, block unauthorized domains and audit new MFA enrollments.

🪙 Bitcoin Depot confirmed on March 23, 2026 that an unauthorized actor accessed portions of its corporate IT environment and transferred approximately 50.903 BTC (about $3.665 million) from company-controlled wallets. The operator of more than 25,000 Bitcoin ATMs said it promptly activated incident response protocols, engaged external cybersecurity experts, and notified law enforcement while believing customer platforms and systems were not affected. On April 6, the company declared the incident material and warned that its cyber insurance may not cover all losses as the investigation continues.

🔍 A German privacy group, Fairlinked, reports that LinkedIn injects a large JavaScript payload into Chrome-based browsers that scans for over 6,000 installed extensions and collects device signals on many interaction events. The code allegedly harvests extension presence, CPU/memory/screen and other metadata and ties those fingerprints to logged-in identities. LinkedIn disputes the characterisation, saying the checks target scraping and policy-violating extensions. Users are advised to consider non-Chrome browsers and reduce extension exposure to limit profiling.

🔍 Sansec researchers uncovered a campaign that embeds a credit-card skimmer into Magento storefronts by hiding it inside a 1×1-pixel SVG element with an onload handler. The handler stores the entire payload as a base64 string decoded via atob() and executed inline to avoid external script detection. When shoppers click checkout a fake Secure Checkout overlay validates card and billing fields in real time and exfiltrates data in XOR-encrypted, base64-obfuscated JSON; Sansec identified six exfiltration domains and published actionable mitigations.

🔐 Google warns that UNC6783 is compromising business process outsourcing (BPO) providers to steal corporate support tickets and other sensitive data for extortion. Attackers use social engineering, live-chat phishing, and spoofed Zendesk-style domains plus fake Okta login pages; observed phishing kits can exfiltrate clipboard contents to bypass MFA and register devices. The group also distributes fake security updates to deliver remote access malware and then contacts victims via ProtonMail; Google recommends deploying FIDO2 keys, monitoring live chat, blocking spoofed domains, and auditing MFA enrollments.

⚠️ Researchers at Jamf observed a ClickFix variation that uses the built-in Script Editor and the applescript:// URL scheme to deliver the Atomic Stealer (AMOS) to macOS users. Victims are lured to fake Apple-themed pages that launch Script Editor with prefilled AppleScript executing an obfuscated "curl | zsh" chain, avoiding the need to open Terminal. The delivered code decodes a base64+gzip payload, writes a Mach-O binary to /tmp/helper, strips extended attributes with "xattr -c", makes it executable, and runs it. Treat Script Editor prompts as high risk and follow official Apple troubleshooting guidance rather than third-party guides.

🔍 Cybersecurity firm Darktrace has identified a new variant of the Chaos botnet that targets misconfigured cloud deployments, expanding the malware's focus beyond routers and edge devices. The 64-bit ELF binary was delivered to a deliberately misconfigured Hadoop honeypot via an HTTP request that created an application embedding shell commands to fetch and execute the payload from pan.tenire[.]com. The updated sample removes SSH- and router-based spread features and instead implements a SOCKS proxy, enabling compromised hosts to relay attacker traffic and broadening the botnet's monetization and evasion capabilities.

🛡️Masjesu, also tracked as XorBot, is a stealthy DDoS-for-hire botnet that targets diverse IoT devices including routers, gateways, cameras, DVRs and NVRs. First observed in 2023 and updated through 2024, it uses XOR-based obfuscation, avoids blocklisted ranges (including DoD IPs), and emphasizes persistence and low visibility. After binding a hard-coded TCP port (55988) the malware establishes persistence, disables common tools like wget and curl, and connects to remote controllers to receive flood commands. Its traffic is concentrated in Vietnam, Ukraine, Iran, Brazil, Kenya and India, with Vietnam accounting for nearly half of observed activity.
