🛡️ Unit 42 identified 18 malicious browser extensions posing as GenAI productivity tools that deliver RATs, infostealers and MitM capabilities. These extensions intercept prompts, exfiltrate credentials and proxy HTTPS responses, often using AI-generated code to accelerate development. Organizations should restrict extensions, scrutinize permissions and treat browsers as critical attack surfaces. Google removed or warned developers after disclosure.

⚠️ A supply chain attack delivered two malicious PyPI releases of PyTorch Lightning (versions 2.6.2 and 2.6.3) published on April 30, 2026; the packages execute automatically on import to harvest credentials. The malicious build hides a _runtime directory with a downloader that fetches the Bun JavaScript runtime and runs an obfuscated 11MB payload that validates GitHub tokens against the api.github[.]com/user endpoint and injects worm-like commits across writable branches. The threat also tampers with local npm packages by adding postinstall hooks, incrementing patch versions, repacking .tgz files, and enabling accidental republishing back to npm. PyPI has quarantined the project; maintainers are investigating, and users should block the affected releases, downgrade to 2.6.1, and rotate any exposed credentials.

🔒 Ukrainian authorities have arrested three suspects accused of compromising more than 610,000 accounts on the online gaming platform Roblox. Investigators say the group used social engineering lures that delivered infostealer malware to harvest usernames, passwords and authentication tokens, then assessed accounts for rare items and Robux. At least 357 high‑value accounts were identified and sold on Russian websites for cryptocurrency, reportedly generating over $225,000. Searches at ten properties recovered computers, storage devices, mobile phones, bank cards, handwritten notes and cash; analysis is ongoing and the suspects face up to 15 years if convicted.

🚨 Ukrainian police arrested three individuals accused of hacking and selling over 610,000 Roblox accounts, reportedly generating about $225,000 in proceeds. The Lviv authorities executed ten searches, seizing $35,000 in cash and multiple devices including 37 mobile phones, 11 desktop PCs, seven laptops, five tablets, and four USB drives. Prosecutors say the suspects — aged 19, 21, and 22 — used info‑stealing malware disguised as a game-enhancer, harvested credentials, categorized accounts by value, and sold high‑value profiles via a Russian website and closed online communities.

🔒 KELA's 2026 report reveals nearly 2.9 billion compromised credentials traced worldwide in 2025, including usernames, passwords, session tokens and cookies sourced from ULP lists, breached email repositories and marketplaces. At least 347 million were obtained by infostealers operating on about 3.9 million infected machines, driven by a surge in macOS infections. The firm warns that AI-driven, autonomous attack workflows and increasing vulnerability weaponization are escalating risk for organizations.

🛡️ A Brazil-based cybercrime group known as LofyGang has resurfaced after more than three years, deploying a new infostealer called LofyStealer (aka GrabBot) that specifically targets Minecraft players. The malware is disguised as a game cheat called 'Slinky' and uses a JavaScript loader to drop and execute chromelevator.exe in memory to harvest browser data. It captures cookies, passwords, tokens, payment cards and IBANs across multiple browsers and exfiltrates them to a C2 at 24.152.36[.]241. ZenoX highlights a strategic shift to a malware-as-a-service model with free and premium tiers and warns that attackers are increasingly abusing GitHub, SEO-poisoned lures and other trusted platforms to distribute malicious payloads.

🔒 Kaspersky researchers discovered a campaign that placed 26 fake crypto-wallet apps in the Chinese App Store, impersonating popular wallets and using benign features to pass review. The malicious apps direct users to phishing pages that prompt installation of a provisioning profile, enabling sideloaded, trojanized wallet builds that request seed phrases. On macOS, infostealers like MacSync use ClickFix lures and can patch legitimate wallet apps to display fake recovery dialogs. The report includes concrete mitigation steps to protect seed phrases and devices.

🚨 Malicious release v0.23.3 of the elementary-data PyPI package was published after an attacker exploited a GitHub Actions script-injection flaw in the project's workflow. The tainted package and its Docker image silently installed an elementary.pth-based loader that exfiltrated SSH keys, cloud credentials, developer tokens and cryptocurrency wallets. A clean v0.23.4 was released, but users who pulled the compromised artifacts must rotate secrets and remediate affected environments.

🔒 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.

🔐 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.

💳 Cybercriminals have trojanized an Android NFC-relay application to capture contactless payment data and PINs, enabling cloning of cards and remote ATM cash-outs. ESET researchers report a new NGate malware variant was injected into the HandyPay app and distributed via a fake lottery site and a spoofed Google Play page targeting Android users in Brazil since November 2025. Traces in the injected code, including emoji markers in debug logs, led researchers to suspect use of generative AI, and ESET has published indicators and a MITRE ATT&CK mapping to aid detection.

📱 ESET has identified a new NGate variant that uses a trojanized version of the legitimate HandyPay NFC relay app to harvest payment card data and PINs. Distributed since November 2025 and focused on Brazil, the malicious app relays tapped NFC data to attacker-controlled devices to facilitate contactless fraud and ATM withdrawals. It requires minimal permissions by leveraging its role as the default payment application, helping it evade detection.

The patched app silently forwards NFC payment card data and captures payment card PINs, exfiltrating them to attacker-controlled C&C infrastructure to enable contactless ATM cash-outs and unauthorized payments. Distribution targeted Android users in Brazil since November 2025 via a fake Rio de Prêmios lottery site and a counterfeit Google Play page; both samples were served from the same domain, indicating a single operator. ESET notified Google and the HandyPay developer; known samples are detected by Google Play Protect and ESET.

🔒 Two phishing campaigns are delivering Formbook infostealer to Windows devices using distinct stealth techniques. One abuses DLL sideloading via RAR attachments containing multiple DLLs and an EXE, while the other hides payloads in obfuscated JavaScript and PDF files that drop PowerShell commands and a custom loader. WatchGuard warns these methods leverage trusted processes to evade detection and urges monitoring of archive attachments, anomalous DLL loads and suspicious PowerShell activity.

🔒 DarkSword and Coruna are two newly discovered, zero-click spyware families actively abused in the wild to compromise iPhones and iPads without user interaction. DarkSword targets iOS 18 with a six‑vulnerability chain and runs filelessly in RAM, while Coruna exploits older releases (iOS 13–17.2.1) via numerous WebKit flaws. Both harvest passwords, messages, photos, browser history and crypto‑wallet secrets; researchers report several thousand infections and advise immediate OS updates and mitigations.

🔒 Researchers at Socket uncovered 108 malicious Google Chrome extensions that collectively amassed about 20,000 installs and reported to a single command-and-control server. Published under five publisher identities, the add-ons posed as games, Telegram sidebars, and enhancement tools while exfiltrating Google account data, hijacking Telegram Web sessions, opening arbitrary URLs, and injecting ads and scripts. Some source files contained Russian-language comments; attribution remains unconfirmed. Users should remove any identified extensions and log out of Telegram Web sessions immediately.
