Ransomware Attack At EB Archbald & Associates, a Provider To Oil-Gas Producers
There was a ransomware attack at EB Archbald & Associates, Inc., which provides energy production accounting services to oil and gas producers and operators.
“On March 23, 2025, we discovered that our company had been the target of a so-called ‘ransomware’ attack,” the Oklahoma City, Oklahoma-based company said in a notice to its 17,000 victims. “The attackers hacked into our system and utilized software to encrypt all data on our servers and Microsoft cloud-based portal. In a subsequent communication the attackers demanded payment of a large sum of money in exchange for their release of a ‘decryption key.’
“We immediately contacted the local office of the Federal Bureau of Investigation (FBI) and notified them of the attack. Per recommendations received from the FBI we refused to meet the attackers’ extortion demands. Five days after their initial attack, and following our refusal to meet their monetary demand, we received a communication from the attackers claiming that they had downloaded information from our systems which they intended to release on the world wide web,” the company said in the notice.
