A local cybersecurity company recently reported alarming news: over 30,000 Australian banking passwords were stolen by hackers using infostealer malware. This threat significantly impacts customers of major Australian banks, including the Big Four: ANZ, NAB, Westpac, and the Commonwealth Bank. Research by the Sydney-based company Dvuln reveals that this malware has infiltrated user devices to collect sensitive banking information. Security experts are deeply concerned. Compromised banking information has surfaced online, marking a severe violation of privacy and security. The Dvuln report indicates that the stolen data is not from direct breaches of banking security systems, but rather from infected customer devices. Infostealer malware is a type of malicious software that poses a significant threat to the integrity of financial transactions and personal data. According to Dvuln, this malware has emerged as one of the most common yet underreported threats facing Australia's financial sector today.
