The text discusses a cyberattack on the supplier AddComm, impacting the distribution of water board tax assessments in the HHNK management area. AddComm notified HHNK of the security breach on May 17, leading to a temporary data hostage situation. Despite the disruption, HHNK managed to deliver tax assessments to residents and businesses by post at the end of May. AddComm confirmed the ransomware attack on May 22 but resumed services safely by early June.
HHNK emphasized the protection of customer privacy, negotiating with cybercriminals to safeguard data interests. While data from HHNK’s secure portal was compromised, phishing attempts through email or messaging platforms were ruled out as HHNK doesn’t provide such contact information to AddComm. Although the extent of personal data exposure remains under investigation, AddComm reassured that less than 4% of households’ data may have been accessible.
The text also addresses concerns about potential misuse of personal information and offers precautionary measures, advising vigilance during payments and providing resources for fraud prevention. Despite assurances from AddComm that compromised data has likely been deleted, HHNK recommends ongoing alertness, especially regarding unexpected mail and payment verifications. Additionally, HHNK acknowledges the disruption in AddComm’s services, causing a delay in accessing water board tax assessments through their online platform, My HHNK, but assures residents of a secure payment environment.
