Production server crash leads to FBI case, despite modest losses

A US software developer faces computer sabotage charges after being arrested over allegations he placed malicious code on his former employer’s computer servers.

Davis Lu, 51, of Houston, Texas, was charged with one count of damaging protected computers following his arrest on Wednesday April 14.

The case traces back to IT issues the yet-to-name Cleveland, Ohio-based start-up experienced on August 4, 2019, which saw production servers crash and staff stranded. systems.

A subsequent investigation discovered “unauthorized code installed on a server, causing an infinite loop to be created and a crash by that server.”

A US Department of Justice declaration on the case adds that the company also found a code that deleted files associated with user profiles – a factor that explains the locking behavior of the system.

Relatively modest losses of over $ 5,000 resulted from the incident.

prime suspect

Lu, a senior software developer at the start-up during the crash-era, was asked to return his computer.

A subsequent forensic investigation would have uncovered internet research on how to elevate privileges, hide processes, and delete large folders and files.

Additionally, the review concluded that Lu “had deleted encrypted volumes, attempted to delete Linux directories, and attempted to delete two more projects” before returning his computer to work.

If Lu was not a suspect in the first place, then the results of an examination of his work computer certainly served to put him in this role, which led to his indictment and arrest.

The suspect faces a single count of allegedly damaging a protected computer.

Although the aggravating incident occurred over 18 months ago, the lawsuits against Lu are still in their infancy and no plea has been filed.

The case, perhaps surprising given the low dollar value of the alleged losses, was investigated by the Cleveland Division of the FBI.
