The company decided to keep the January breach a secret in order to monitor the intruders' actions.
Dutch ISP KPN recently acknowledged that it suffered a data breach in January.
"Anonymous hackers took credit for the breach and even published a Pastebin file that contained the credentials of 500 customers to prove that they managed to gain access," writes Softpedia's Eduard Kovacs.
"On January 28, when the breach was discovered, after consultations with law enforcement and Dutch government agencies, the firm decided to keep everything a secret, allegedly to allow them to monitor the attacker’s moves," Kovacs writes. "This obviously failed, since a short while after the incident was made public and the 500 credential sets were published, the ISP decided to suspend email access, advising customers to change their passwords to prevent unfortunate incidents."
