🛏️ The Play ransomware group claims to have stolen confidential MyPillow data and threatened a public dump, while CEO Mike Lindell denies any breach and calls the allegations politically motivated. Lindell says MyPillow stores no sensitive data internally and has received no ransom demands, attributing data handling to third parties. The Play group's leak portal set a deadline for release, leaving the truth pending until the deadline passes. The article warns that third-party handling of data still exposes organisations and individuals to meaningful risk.

🔒 A Romanian national was sentenced to 56 months in federal prison after pleading guilty to aggravated identity theft and unauthorized access to an Oregon state government computer network. The 46-year-old, known online as "inthematrixl," also sold access and stolen personal data from other U.S. victims, causing at least $250,000 in losses. Authorities coordinated internationally to arrest and extradite him, and the court ordered forfeiture of cryptocurrency and supervised release.

🔍 Wiz has attributed a cluster named Jinx-0164 to a campaign targeting cryptocurrency firms with custom macOS malware, recruiter-themed lures and supply-chain tampering. The actor relies on LinkedIn-based social engineering and lookalike meeting domains to deliver a Python stealer/remote access tool called Audiofix, which poses as an audio driver and harvests keys, credentials and wallet data. They also abuse stolen GitHub tokens to inject backdoors into CI/CD repositories, causing builds to propagate the malware across development environments.

🛳️ Carnival Corporation confirmed a data breach affecting nearly 6 million customers after attackers used social engineering to access an employee account on April 10, 2026. The company began notifying 5,995,277 individuals and engaged third-party security experts while blocking the unauthorized activity. Analysis of leaked data indicates exposed names, dates of birth, emails, genders, locations, and loyalty program details tied to Holland America’s Mariner Society.

📄 ESET summarizes notable APT activity observed between October 2025 and March 2026, highlighting China-, Iran-, North Korea-, and Russia-aligned operations alongside unattributed clusters. The report illustrates geopolitical drivers behind campaigns, describes new tooling and supply-chain compromises such as a trojanized axios package, and notes destructive incidents impacting critical infrastructure. ESET confirms protections by its products and notes the report reflects a subset of its Threat Intelligence.

🛡️ The FBI warns of a gang dubbed the Silent Ransom Group (SRG) that has shifted from phishing and remote access scams to in-person impersonation of IT support, gaining physical access to devices to install malware or exfiltrate data. The group, active since at least 2022, typically steals data to extort victims without using ransomware encryption. Indicators include unauthorized installs of remote-access tools, new USB or external drive activity, and unexpected data uploads to services like OneDrive or Google Drive.

🛡️ Microsoft uncovered a targeted cryptojacking campaign that lures owners of high-performance PCs to malicious download pages for utilities like CrystalDiskInfo and HWMonitor. The attackers used SEO poisoning and, in some cases, manipulated AI chatbots to surface attacker-controlled download links. Infected ZIP archives include legitimate utilities and a malicious DLL that installs the ScreenConnect remote access tool, enabling persistent access and deployment of a process-hollowing loader that ultimately launches GPU miners.

🛡️ WatchGuard and ESET report two active campaigns spreading Windows and Android banking trojans across Latin America and Europe. The Grandoreiro campaign leverages DLL side-loading, WebRTC/STUN/ICE communications, and phishing to target Portuguese banks and international financial services. ESET details BTMOB, a rapidly evolving Android RAT sold as a service with an APK builder that enables mass phishing-based distribution and remote device control.

📧 Recent phishing campaigns exploit Google’s AppSheet platform to send convincing emails from a legitimate noreply{@}appsheet.com address, making them likely to bypass filters. Attackers craft personalized messages — urgent warnings or enticing job offers — to trick victims into submitting identity details on clone sites, then harvest credentials and data. The compromises can lead to account takeover, device control, and secondary targeted attacks using the stolen information.

🛡️ Researchers uncovered a malicious npm package named mouse5212-super-formatter that exfiltrates files from the /mnt/user-data directory used by Anthropic's Claude AI. OX Security describes the campaign, codenamed Malware-Slop, as a postinstall script that authenticates to GitHub using environment or hard-coded tokens, creates or targets a repository, and uploads local files to an attacker-controlled account. The package has been downloaded hundreds of times, and the linked GitHub account—created shortly before the package appeared—has since disappeared. Analysts noted the actor leaked a private token, suggesting poor OPSEC and possibly AI-assisted malware creation.

🛡️ CrowdStrike, Google, and The Shadowserver Foundation coordinated to disrupt the Glassworm botnet by simultaneously takedown of four resilient C2 channels. The threat abused Solana blockchain memo fields, the BitTorrent DHT, Google Calendar events, and traditional VPS-hosted servers to persist and evade mitigation. Active campaigns targeted developers via malicious OpenVSX and VS Code extensions and later poisoned GitHub and npm artifacts. Infected hosts now beacon to a CrowdStrike-controlled IP and YARA rules have been published to detect compromise.

🛡️ CrowdStrike, together with Google and the Shadowserver Foundation, announced the simultaneous disruption of all command-and-control channels used by GlassWorm, a persistent campaign that has targeted software developers since early 2025. The operators trojanized VS Code extensions and poisoned npm and Python packages to deliver a data-theft framework capable of credential harvesting and system profiling. Multiple resilient C2 resolution layers were used — Solana memo fields, BitTorrent DHT, Google Calendar events, and commercial VPS hosts — all of which were neutralized in the coordinated action. CrowdStrike attributes the activity to likely Russia-based cybercriminals and warns about the severe risk posed by supply chain compromises to developer ecosystems.

🎯 Group-IB has identified over 4,300 fraudulent domains impersonating FIFA since last August, organized across six schemes and four threat actors targeting 2026 World Cup fans. The main operator, dubbed Ghost Stadium, uses a Chinese-speaking developer and a phishing kit that clones fifa.com, including its PingIdentity SSO flow, and leverages paid Facebook ads. Other actors include domain squatters, a PhaaS supplier and infostealer campaigns, which have already harvested around 2,500 FIFA credentials. Group-IB warns ticket fraud losses could reach into the hundreds of millions and advises fans to buy only from fifa.com, avoid crypto-based offers and enable MFA.

🔒 The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to patch a critical, actively exploited privilege escalation flaw in the LiteSpeed cPanel user-end plugin, tracked as CVE-2026-48172. LiteSpeed released urgent updates to fix the issue in the lsws.redisAble function and advised administrators to check logs and block suspicious IPs. CISA added the flaw to its known exploited vulnerabilities catalog and required patches by May 29 under BOD 22-01.

🔒 The Dutch National Police arrested a 35-year-old man from Buren suspected of multiple unlawful intrusions into AFC Ajax's computer systems earlier this year. The intrusions allowed access to data belonging to a few hundred individuals, modification of fewer than 20 stadium bans, and reassignment of purchased tickets. Ajax patched the exploited vulnerabilities, reported the breach to the Dutch Data Protection Authority and police, and the investigation remains ongoing.

🛡️ Microsoft warns of an active cryptojacking campaign that leverages AI chatbot interactions to surface malicious download sites. The attacks impersonate legitimate utilities and target high-performance GPU systems, using ZIP archives with sideloaded rogue DLLs to install ScreenConnect and deliver GPU miners. The campaign establishes persistent remote access, configures Defender exclusions, and supports multiple miners while evading analysis tools.

🛡️ Mandiant found attackers exploited a critical unauthenticated deserialization flaw (CVE-2026-5426) in KnowledgeDeliver LMS to deliver the Godzilla web shell. The issue stemmed from a shared hardcoded ASP.NET machineKey across customer deployments, allowing signed malicious ViewState payloads and remote code execution. Compromised installations were used to push fake installers, deploy Cobalt Strike beacons, and modify site scripts to load attacker-controlled payloads.

🔒 Charter Communications confirmed a data breach after the ShinyHunters extortion group claimed to have stolen millions of customer records. The company says it is notifying authorities and maintains that No sensitive personal information (PI) or CPNI was exfiltrated. ShinyHunters alleges the intrusion began via a vishing attack that compromised an employee's Microsoft Entra account and allowed access to Salesforce data.

🔒 The FBI has alerted organisations to Kali365, a phishing-as-a-service platform that can hijack Microsoft 365 accounts without stealing passwords and can bypass multi-factor authentication. Launched in April 2026 and sold via Telegram, Kali365 offers AI-generated lures, automated templates, dashboards, and OAuth token capture for as little as $250 monthly. The kit exploits Microsoft’s device code flow, tricking victims into authorising attacker devices on legitimate Microsoft pages, granting access to Outlook, Teams, and OneDrive. The FBI recommends blocking device code flow with a conditional access policy in Microsoft Entra ID and deploying phishing-resistant MFA such as hardware security keys.

🔒 Researchers at SafeDep uncovered the Megalodon campaign that pushed 5,718 malicious commits into 5,561 public GitHub repositories during a six-hour window on May 18. The attackers modified GitHub Actions workflows to embed base64-encoded bash payloads designed to exfiltrate CI-exposed secrets such as cloud credentials, SSH keys, and OIDC tokens. The campaign used compromised Personal Access Tokens or deploy keys and forged author identities like build-bot to directly commit changes without PRs, and delivered two payload variants that either ran on every push or via workflow_dispatch triggers.
