ENT18198622
TALX is working with Entergy to notify former and current Entergy employees whose 2016 W-2 data have been acquired by criminals from the TALX portal. An unauthorized third party gained access to the accounts. It was done primarily by successfully answering personal questions about the affected employees in order to reset the employees’ PINS. It gave unauthorized access to certain Entergy employees’ online portal accounts and electronic W-2 tax forms for the tax year 2016 or earlier. TALX has arranged for two years of complimentary restoration and assistance help for affected Entergy employees.
