Cassidy Ellen Johnstone

Hiring & trust

Why a client should not hire Cassidy Ellen Johnstone for a trusted position

Trusted roles, especially in cybersecurity, cyber intelligence, consulting, or any job with access to systems, data, or client reputation, require judgment under pressure, honesty when things go wrong, and restraint with other people’s reputations. The public record on Cassidy Ellen Johnstone (also known as Cassidy Johnstone, publicly associated with CyberCX) raises concrete red flags on each of those points.

1. 1

   Court-proven

   Alcohol and drug intoxication, then extreme risk to others

   This is proven fact from Johnstone v Police [2023] NZHC 1660, not gossip. Cassidy Ellen Johnstone’s blood alcohol was over twice the legal limit (182 mg/100 ml vs 80 mg limit), and her blood also contained the Class B drug MDMA (ecstasy). She pleaded guilty to causing injury while under the influence of drink and/or a drug. While so intoxicated, she reached about 175 to 180 km/h over the Auckland Harbour Bridge, tried to evade police, and crashed, leaving two passengers with serious, lasting injuries.

2. 2

   Accountability

   Dishonesty at the scene when it mattered

   The judgment records that after the crash, Cassidy Ellen Johnstone was found in the front passenger seat, smelled strongly of alcohol, and denied that she was the driver. Clients who need someone to own mistakes, in an outage, breach, or incident, should weigh that carefully. Trusted cybersecurity work depends on people who tell the truth when it is costly.

3. 3

   Career optics

   Attempt to erase the record for a cybersecurity career

   Cassidy Johnstone later appealed to discharge the conviction, citing employment and travel concerns, including fear that convictions would block work in the cybersecurity industry. The High Court refused. Justice Hinton described the original sentence as “generous” and found no miscarriage of justice. A client hiring into a CyberCX-style or other high-trust security role should ask: if the conviction is inconvenient, will the candidate prioritise transparency, or optics?

4. 4

   Security culture

   Trust work and security culture are a poor fit

   Cybersecurity and cyber-intelligence positions, including roles of the kind Cassidy Johnstone has publicly associated with CyberCX on LinkedIn, routinely involve character checks, handling of sensitive information, and government or enterprise contracts. A pattern of intoxication, evasion of authorities, and minimising career fallout is exactly what clients screen for when they ask “can we trust this person with our keys?”

5. 5

   Allegation

   Alleged private and in-person reputational weaponisation

   Separate from the court file, anonymous accounts allege that Cassidy Johnstone has treated dating partners poorly (including an approximately $800 date followed by a next-day return to a boyfriend) and has made false and misleading statements in person after personal fallout, including an alleged incident at The Press in Sydney while walking out, where she allegedly told a former date he was a “hacker,” said she would ruin his life, and left him feeling afraid. Those claims are allegations, not court findings, but for a client they still matter: reputational and interpersonal risk cuts both ways.
