Woman charged in $265K cyber scam targeting Calgary business

A five-month investigation into a sophisticated cyber fraud scheme has led to charges against an Edmonton woman accused of defrauding a Calgary oil field supply company out of more than $255,000.
Calgary police say the company first reported the fraud on May 5, after discovering that a payment they had sent was intercepted and redirected to a fraudulent bank account.
Investigators believe the company’s email system was compromised, allowing cybercriminals to alter a legitimate invoice and reroute the funds.
Further investigation revealed the fraudulent account also contained an additional $10,000 obtained from the Canada Revenue Agency (CRA) through similar means.
On Oct. 9, Calgary police, with help from the Edmonton Police Service, executed four search warrants in Edmonton. Officers seized $17,830 in Canadian cash, $1,414 in U.S. cash, and 10 digital devices believed to be connected to the scam.
The full $265,000 was successfully recovered and returned to both the company and the CRA.
Rosswida Tjiueza, 38, of Edmonton, has been charged with two counts of fraud over $5,000 and two counts of possession of proceeds of crime over $5,000.
“Cyber fraud investigations are often highly complex, involving multiple jurisdictions, digital forensics, and coordinated law enforcement efforts,” said CPS Insp. Keith Hurley in a statement. “This fraud underscores how sophisticated cybercriminals can exploit business communications to redirect substantial funds without immediate detection.”
Anyone who believes they have been the victim of a cyber-enabled crime is urged to report it by calling 403-266-1234. Anonymous tips can also be submitted to Crime Stoppers.
