The Netwalker ransomware operators have published the stolen data for K-Electric, Pakistan’s largest private power company, after a ransom was not paid.
On September 7th, 2020, K-Electric suffered a Netwalker ransomware attack that disrupted online billing services, but not the supply of power.
Soon after, BleepingComputer obtained access to the Tor ransom payment page for K-Electric’s attack, where ransomware operators demanded a $3,850,000 payment. The attackers also stated that they would release files stolen during the attack if a ransom was not paid.
In a statement to BleepingComputer, K-Electric denied that any data was stolen from the company.
“Karachi, 11th September 2020: Following the attempted cyber incident earlier this week and its on-going forensic investigation, the power utility has confirmed that initial investigation shows all customer data has remained intact and secure, reiterating that critical customer services including bill payment solutions, customer care centres and 118 call-centre are operational and fully functional.”
Netwalker publishes stolen data
This week, Netwalker has released an 8.5 GB archive of files allegedly stolen from K-Electric during the September ransomware attack.
Pakistani cybersecurity firm Rewterz, who examined the archive contents, told BleepingComputer that it contains sensitive information like financial data, customer information, engineering reports, maintenance logs, and more.
This data includes unaudited profit and loss statements, engineering diagrams for turbines, and pictures of customer statements, which are marked as being from K-Electric.
With the varied information disclosed as part of this attack, customers should be concerned that their personal information may have been exposed.
It is also important for K-Electric to be transparent about the exposed info so employees and customers can adequately protect themselves.
BleepingComputer has contacted K-Electric for another statement but has not received a reply.
