The largest fuel distribution line in the United States had to be shut down in early May due to a blackmail malware attack. Victim Colonial Pipeline According to a security company expert who assisted the company, the attackers entered a dark network with a leaked password.
Security company Mandiantin deputy director Charles Carmakal said in an interview To Bloomberg, attackers could access remotely via a vpn connection. The vpn user account used by the attackers was no longer actively in use at the time of the attack, but its credentials still allowed access to the company’s systems.
The password used to log in has been found among the passwords leaked to the dark network. It is likely that the employee has used the same password in another service that was previously hacked.
That user has not had two-step authentication, so the blackmailers logged in with just a username and password. It is not known how the attackers found out the correct username. No traces of the fishing on that worker have been found.
The attackers entered the systems on April 29th. More than a week later, on May 7, at five o’clock in the morning, one of the employees noticed a ransom demand on the control room computer screen. The matter was reported to the supervisor and shortly after six in the morning the entire distribution line was closed.
