polleninformation.at Listed by apt73 Ransomware Group

On April 27, 2026, the Austrian website polleninformation.at appeared on the leak site of the ransomware group apt73. The listing states that internal files were exfiltrated during a ransomware attack, exposing a file described as containing personal information and passwords across 22,140 lines.

Reported Details from Reporting

Public reporting indicates the incident involved a ransomware deployment that led to data exfiltration. The leaked material is characterized as internal files from the pollen information service, which provides seasonal allergy data to the public. The apt73 leak page lists the victim under the category of personal info and passwords, though the exact number of individuals affected remains unknown. No evidence has surfaced that the data has been broadly distributed beyond the group’s leak site at the time of reporting.

Why This Matters for You and Your Family

When a seemingly specialized site like a pollen tracker is breached, ordinary people who used it to check daily allergy forecasts can find their details exposed. If you or anyone in your household entered an email address, created an account, or reused a password on polleninformation.at, that credential may now be in the hands of a ransomware operator. Personal information and passwords together allow attackers to attempt logins on other services where you use the same details. For families, this risk extends to shared accounts or children who may have registered using a parent’s email. A single breach like this can quietly sit undetected for months until the credentials surface in fraud or identity theft attempts.

The Doxxing and Identity-Chain Risk

Credential leaks rarely stop at one site. Attackers combine exposed emails, passwords, and any associated personal details to map connections across social media, gaming platforms, and other accounts. This process, known as identity chaining, can lead to doxxing where an attacker assembles enough information to harass, impersonate, or extort you or your children. Gaming accounts are particularly vulnerable because they often link to the same email or phone number used on everyday services. A password stolen from a pollen website can become the key that unlocks a child’s Fortnite or Roblox profile, exposing chat logs, friend lists, and sometimes payment methods. Once one account falls, the chain grows quickly.

apt73’s Publicly Known Track Record

Public reporting attributes the activity to a group known as apt73. The group emerged in recent years and has targeted organizations across multiple sectors with a standard ransomware playbook: initial access often gained through phishing or exploited vulnerabilities, followed by data exfiltration and encryption of systems. After deployment, apt73 typically posts samples or full datasets on its leak site if victims do not pay the demanded ransom. Notable prior victims have included various mid-sized enterprises and service providers, though details on many remain limited. Their extortion style relies on the public pressure created by listing victims and threatening to release sensitive files.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup of exposed records.
• Rotate the password used on polleninformation.at anywhere it is reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next exposure is caught in hours, not months.
• Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts that often chain back to the same credentials.
• Let remediation specialists handle takedown requests across data brokers and leak sites on your behalf while you focus on securing your accounts.
