Naftor and Grupa Pern (Naftoport/ SIARKOPOL/ SARMATIA/ NAFTOSERWIS) is the most dangerous Listed by alphv Ransomware Group

On November 14, 2023, the ransomware group Alphv listed Naftor Sp. z o.o. and its parent Grupa PERN (which includes Naftoport, Siarkopol, Sarmatia, and Naftoserwis) on its leak site, warning that internal files had been exfiltrated and would be published if demands were not met. The listing explicitly threatens the companies’ clients and partners, stating that continued cooperation could expose their own confidential data and that the attackers had already leveraged the Polish fuel-logistics firm’s vulnerabilities to penetrate partner networks.

Primary Disclosure Details

The Alphv leak site posting does not quantify the number of records affected or list specific data types beyond “internal files” and “confidential documents.” It claims the companies failed to comply with European Union GDPR requirements and asserts that any contacts with Naftor or Grupa PERN now carry legal and financial risk. The disclosure warns that all confidential documents will be made public in the near future and that the group has already used the victim’s network as a pivot to reach partners and clients. No ransom amount or exact deadline appears in the public listing.

Why This Matters for You and Your Family

If you or any member of your household has done business with Naftor, Grupa PERN, or any of its subsidiaries, your personal or business information may already sit inside the exfiltrated archive. Even if you never directly contracted with them, supply-chain exposure means data you shared with another vendor could have been swept up when Alphv moved laterally. Internal files in fuel and logistics sectors routinely contain contracts, invoices, employee details, and correspondence that can be repurposed for identity theft, spear-phishing, or blackmail. Ordinary families who ship goods, work at partner firms, or simply appear in vendor databases face the same downstream risk as the primary victim.

Doxxing and Identity-Chain Implications

Credential leaks and internal documents from incidents like this frequently cascade into account takeovers across unrelated services. An email address or password pair taken from a logistics vendor can unlock personal webmail, banking portals, or children’s gaming accounts. Once attackers link your work identity to home accounts, they can build a complete profile that includes addresses, phone numbers, and family relationships. This is exactly how doxxing chains form: one breach becomes the seed that sprouts further compromises months later. Gaming accounts belonging to you or your children are especially vulnerable because kids often reuse credentials learned at home.

Alphv’s Publicly Known Track Record

Public reporting attributes the Alphv group, also known as BlackCat, with emerging in late 2021 after the shutdown of REvil. The gang has targeted organizations across healthcare, manufacturing, and critical infrastructure, including several European energy and logistics entities. Their typical playbook combines initial access via compromised credentials or vulnerable remote-desktop services, followed by rapid lateral movement, data exfiltration, and dual extortion: demanding ransom for decryption keys while simultaneously threatening to publish stolen files. The Naftor/Grupa PERN listing follows this pattern, using public pressure on partners as leverage to force the primary victim to pay.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to scrub what you can.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught in hours rather than months.
• Rotate any password you ever used at Naftor, Grupa PERN, or their subsidiaries anywhere it has been reused, and switch on 2FA through an authenticator app instead of SMS.
• Cover the entire household — DoxxScan family coverage extends to dependents and children’s gaming accounts that often chain back to the same address or credentials.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing day-to-day accounts.

The incident demonstrates how a single logistics-sector breach can ripple outward and place ordinary families in the crosshairs long after the initial attack. Acting quickly on credential hygiene and identity mapping limits how far attackers can travel down the chain. Start your DoxxScan trial today; its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage including children’s gaming accounts give you and your family a practical defense against the next wave of exposure.
