Study Notes
Types of Hackers
- Elite hackers are highly technical individuals who can write scripts to exploit vulnerabilities and discover new ones.
Insider Threats
- Insiders are more dangerous than outside intruders because they have access and knowledge to cause immediate damage.
- Insiders often know the security systems and can avoid detection.
- Insider attacks can be accidental or intentional.
- Examples: Chelsea Manning and Edward Snowden.
Physical Access
- Numerous individuals have physical access to company facilities, including custodial crews, contractors, and partners.
Criminal Organizations
- Criminal organizations employ structured threats with planning, financial backing, and possibly collusion with insiders.
- Structured threats involve greater planning, more financial backing, and possibly corruption of insiders.
- Tactics, techniques, and procedures (TTPs) are methods used by adversaries to assist in identification and defense.
Threat Intelligence
- Threat intelligence gathers information from various sources to focus defenses against likely threat actors.
- Threat intelligence is crucial for detecting threats and prioritizing responses.
- There are two comprehensive forms: Information Sharing and Analysis Centers (ISACs) and Information Sharing and Analysis Organizations (ISAOs).
Open Source Intelligence
- Open source intelligence collects threat intelligence information from public sources.
- Public sources include news articles, blogs, and government reports.
- Open source intelligence helps in understanding adversary TTPs.
Historical Incidents
- Morris Worm (1988): first large-scale attack on the Internet; 6000 infected, $100 million in damage.
- Citibank and Vladimir Levin (1994): broke into bank's cash management system; stole $10 million, recovered $9.6 million; 3 years in jail.
