(Adds shares in paragraph 2, details about a separate cyber
incident in paragraph 3 and information about Monday's incident
through paragraphs 4-7)
Oct 7 (Reuters) - Home security firm ADT Inc ADT.N
said on Monday an unauthorized actor had illegally accessed its
network using credentials obtained through a third-party
business partner.
Shares of the company fell 1.8% after the bell.
Monday's incident comes just months after the company
reported a separate cybersecurity breach where the unauthorized
actors accessed ADT's customer order details and "limited"
customer information, including email addresses, phone numbers
and postal addresses.
The company has taken steps to shut down the unauthorized
access and launched an investigation into the incident, which it
said is at an early stage and still ongoing.
ADT said, in a regulatory filing, that the unauthorized
actor took certain encrypted internal data associated with
employee user accounts. However, it does not believe any
customers' personal information or their security systems were
compromised, the company added.
ADT said it is working closely with federal law enforcement
and external cybersecurity experts to help with its response to
the incident.
The company has also implemented countermeasures to help
safeguard its information technology assets and operations,
which have resulted in some disruptions to ADT's information
systems, the company said in the filing.
