CanisterSprawl: pgserve Compromised on npm: Malicious Versions Harvest Credentials and Exfiltrate to a Decentralized ICP Canister

On April 21, 2026, compromised versions of pgserve (1.1.11, 1.1.12, and 1.1.13) were published on npm, containing a 1,143-line credential-harvesting script that executes during the postinstall phase of npm install. The malware functions as a supply-chain worm, reinjecting itself into other packages if it finds an npm publish token. Stolen credentials are encrypted using RSA-4096 and AES-256 and exfiltrated to a decentralized Internet Computer Protocol (ICP) canister. The last legitimate release was v1.1.10, published on April 17, 2026. The malware was detected by StepSecurity AI Package Analyst and Harden Runner, which flagged the compromised versions as Critical / Rejected and confirmed live exfiltration during analysis. The injected script performs operations such as harvesting environment variables, collecting filesystem secrets, encrypting payloads, and propagating to other npm packages and Python packages if a PyPI token is detected. The exfiltration domains have been added to a global block list.

New Windows RPC Vulnerability Lets Attackers Escalate Privileges Across All Windows Versions

PhantomRPC is a significant architectural vulnerability in the Windows Remote Procedure Call (RPC) framework that allows local privilege escalation to SYSTEM-level access across all Windows versions. Discovered by Kaspersky's Haidar Kabibo at Black Hat Asia 2026, this vulnerability stems from the RPC runtime's failure to verify the legitimacy of a responding server during calls to offline or disabled servers. Attackers can exploit this by setting up a malicious RPC server that impersonates a legitimate endpoint, using the RpcImpersonateClient API to escalate privileges from low-privileged accounts to SYSTEM or Administrator levels. Five distinct exploitation paths have been identified: 1. gpupdate.exe coercion: An attacker can intercept an RPC call made by the Group Policy Client service when executing gpupdate /force, granting SYSTEM-level access if TermService is disabled. 2. Microsoft Edge startup: Launching msedge.exe triggers an RPC call to TermService, allowing privilege escalation from Network Service to Administrator via a spoofed endpoint. 3. WDI background service: The Diagnostic System Host polls TermService regularly, enabling an attacker to exploit this without user interaction. 4. ipconfig.exe and DHCP Client: Running ipconfig.exe initiates an RPC call to the DHCP Client service, allowing a Local Service attacker to elevate privileges if DHCP is disabled and a fake server is present. 5. w32tm.exe and Windows Time: An attacker can expose a named pipe endpoint, allowing them to impersonate any privileged user executing the Windows Time executable. The vulnerability was reported to Microsoft on September 19, 2025, but Microsoft categorized it as moderate severity and closed the case without a patch, as the attack requires SeImpersonatePrivilege, which is granted by default to certain accounts. Organizations are advised to implement defensive measures such as enabling RPC monitoring, ensuring legitimate services are running, and restricting SeImpersonatePrivilege. Kaspersky has provided tools for auditing environments for exploitable RPC call patterns through the PhantomRPC GitHub repository.

Fileless Malware and Email Authentication Gaps

Fileless malware operates stealthily within networks, utilizing legitimate system tools like PowerShell and Windows Management Instrumentation (WMI) to execute malicious code in memory without leaving traces on disk. Traditional antivirus solutions struggle to detect these threats due to their reliance on file signatures. The primary vector for fileless malware is email, where attackers use spoofed messages to trick users into activating malicious scripts. Misconfigurations in Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records create vulnerabilities that attackers exploit to deliver spoofed emails. Traditional endpoint protection mechanisms are inadequate against fileless attacks, necessitating a shift towards behavioral analysis for detection. Organizations must assess their preparedness by ensuring proper email authentication configurations and enhancing endpoint security capabilities. Integration among security teams and updated employee security awareness programs are also essential. Sendmarc helps organizations mitigate vulnerabilities by providing visibility into SPF, DKIM, and DMARC configurations and enforcing DMARC to block unauthenticated messages.

Safeguarding Against the Personal Attack Chain in the Age of “Always On” Connectivity

The cybersecurity industry has focused on protecting corporate perimeters, but cybercriminals are increasingly targeting executives and their families, exploiting personal vulnerabilities. Executives are twelve times more likely to be targeted than average employees, with over half experiencing personal breaches. The Personal Attack Chain is a multi-stage process where attackers exploit an executive's personal digital footprint to gain access to corporate resources. The stages include reconnaissance, intrusion, lateral movement, and action on objectives. Reactive security measures are insufficient; proactive intelligence is necessary to identify threats before they reach organizations. Home security is often compromised by vendors, and travel increases vulnerability. Digital Executive Protection (DEP) is becoming essential for safeguarding executives and their families, balancing privacy, convenience, and security. Effective strategies include minimizing digital footprints, safeguarding devices and networks, providing identity theft protection, and educating executives on online safety. Personal cybersecurity is now a corporate imperative, requiring a holistic approach to protect individuals and organizations alike.
