Researchers predict an increase in the use of banking malware for cyber espionage operations within non-financial and government organisations.
“Cyber criminals have come to appreciate that sensitive personal and organisational information are the currency of their ‘hacker economy,’” said Vincent Weafer, senior vice-president at McAfee Labs.
“In the enterprise, we see password-stealing Trojans evolving to become information-gathering tools for cyber espionage attacks,” Vincent Weafer said.
According to Weafer, highly-targeted attacks are achieving new levels of sophistication, whether they target log in credentials or intellectual property and trade secrets.
