A recent case has highlighted that ransomware threats can sometimes come from within an organisation. Daniel Rhyne, a 57-year-old IT administrator from Kansas City, Missouri, has been accused of holding his own company hostage by locking down their systems and demanding a ransom to restore access.
The incident occurred in November last year when Rhyne was employed at an industrial company based in Somerset County, New Jersey. According to the Federal Bureau of Investigation (FBI), Rhyne allegedly took control of the company’s network by resetting the passwords of network administrator accounts as well as those of hundreds of employees. He then proceeded to delete critical backups and locked out both servers and workstations, crippling the organisation’s operations.
An hour after initiating the attack, Rhyne allegedly sent an email to the company's employees informing them of the situation and demanding a ransom in exchange for unlocking the systems. The FBI claims this was an attempt at extortion, with Rhyne threatening further damage if his demands were not met.
Rhyne’s actions were investigated by the FBI, and he has been charged with multiple counts, including extortion, intentional damage to a protected computer, and wire fraud. Should he be convicted of all charges, he faces up to 35 years in prison and a $500,000 fine, as reported by The Register.
Several pieces of evidence were gathered by the FBI to support their case against Rhyne. For instance, he allegedly used a tool known as PsPasswd, a Windows Sysinternals utility, to reset user passwords. The new password set for the accounts was "TheFr0zenCrew!", a telling detail that investigators believe connects him directly to the attack. Rhyne also reportedly kept a hidden virtual machine (VM) on his company-issued laptop, allowing him to maintain remote access to the network's administrative controls.
Adding to the case, the FBI noted that Rhyne's digital activities prior to the attack were suspicious. He allegedly used his work laptop to search for ways to alter administrator passwords via command-line tools, which are often used by IT professionals to manage networks remotely. Investigators claim that on the day of the attack, Rhyne was seen logging into his work laptop, conducting these searches, and reviewing company password spreadsheets while also accessing the hidden VM.
The fact that he used his company-issued laptop to perform these actions leaves a strong digital trail linking him to the crime. The FBI’s detailed investigation paints a clear picture of how the attack was executed, utilising common IT tools to gain unauthorised control over the company’s systems.
If Rhyne is found guilty, his actions could serve as a warning to organisations about the potential for internal threats. It highlights the need for companies to have strong security protocols in place, not just to defend against external hackers but also to safeguard against malicious insiders who have privileged access to sensitive systems.
This case illustrates how cyberattacks are evolving and how attackers, even those within the organisation, can exploit their knowledge and access to launch devastating attacks. Organisations must remain vigilant and continually monitor for suspicious behaviour, no matter the source, to protect their critical digital infrastructure.
