An Australian hacker has pleaded guilty to infecting 3,000 computers with an information-stealing Trojan.

Anthony Scott Harrison, 21, from the Black Forest area near Adelaide, pleaded guilty on Monday to seven computer hacking offences over the attempted cybercrime scam, UPI reports.

He used an unnamed strain of malware to swipe bank logins and credit card details.

Harrison also admitted creating a 74,000-strong bot army of compromised Windows machines capable of launching denial of service attacks.

Harrison, pictured here leaving a South Australian District Court, will be sentenced in September.. ®
