Fired IT Worker Jailed for Sabotaging Former Employer’s System
A disgruntled IT whizz has been locked up for hacking into the computer network of a company that fired him — causing a major system outage.
Vladimir Yanpolsky, 45, from Hungerford Square, Weybridge, was sentenced to three-and-a-half years behind bars at Kingston Crown Court on Wednesday, 22 January. He was found guilty of breaching the Computer Misuse Act 1990 after a thorough investigation.
Remote Hack Caused Critical System Failure
On 5 March 2017, a London-based IT services firm suffered a severe network crash. Police inquiries quickly traced the attack back to remote access from suspicious IP addresses. The trail led straight to Yanpolsky, who had been sacked months earlier.
Detectives from the Met’s Cyber Crime Unit matched the IPs to Yanpolsky’s home and new workplace. He was arrested just three days later on 8 March 2017.
Denies Offence but Evidence Mounts
During police interviews, Yanpolsky denied all wrongdoing and was released on bail while officers seized his devices. Subsequent forensic analysis tied him firmly to the cyberattack.
He was formally charged in September 2018 under the Computer Misuse Act.
Detective Chief Inspector Kirsty Goldsmith said: “Yanpolsky used his specialist knowledge of a company he was fired from in acrimonious circumstances to deliberately sabotage its IT operations. Since his arrest, he has shown no remorse for the consequences of his actions. I am proud of the tenacity, dedication and skill of the officers during a painstaking investigation, who presented strong technical evidence to the court leading to this conviction.”
Justice Served for Cyber Sabotage
This case sends a clear warning: insider knowledge is no excuse for cybercrime. Yanpolsky’s hefty jail term highlights the risks of vengeful IT attacks on businesses.
