Case #3: Email link installed malware to hijack
bank account credentials
Business
Problem:
This SMB size manufacturing company
had $94,700 removed from a corporate bank account from an
unknown person. The incident was reported to the bank and
FBI to investigate. Due to the small amount of money,
nominal resources were assigned with no strong leads. Bank
suspected a person/group in Eastern Europe that intercepted
account credentials to withdraw funds.
Timeframe: Four weeks
Budget: $35,000
Business Solution:
After the shocking discovery was made, it was time to implement
rock-solid security solutions to prevent this from happening
again. The first step was to determine from a forensics
perspective if a PC at the company had malware installed.
A malware program was discovered on one of the PC's in the
accounting department. It was determined based on
interviews that various links may have been "clicked" by the end
user as a habit to review emails. The PC was removed from
service for any future prosecution. The entire company
environment was scanned for viruses, malware, bot-nets, and
adware to "sanitize" the infrastructure. New firewalls
were installed, VLAN's set up in accounting, and only dedicated
PC's that went through extensive "hardening" and proactive
monitoring tools now access financial systems.
Business Results: The SMB learned a painful lesson that took
IT Security to a whole new level that not only protected on-line
banking transactions, but was a significant improvement to
securing the entire organization ranging from intellectual
property to HR data about employees.
