  • Baiting: Offering something enticing to lure victims into a trap.
  • Tailgating: Following authorized personnel into restricted areas.

Famous Social Engineering Attacks

Kevin Mitnick, one of the most notorious hackers, used social engineering to bypass security systems and access sensitive information in the 1990s. His techniques highlighted the power of psychological manipulation in cybercrime.

Advanced Persistent Threats (APTs)

What are APTs?

APTs are prolonged and targeted cyber attacks, typically orchestrated by well-funded and skilled adversaries, such as nation-states or organized crime groups.

Characteristics of APTs

  • Long-term presence in the target’s network.
  • Use of sophisticated techniques to evade detection.
  • Specific targets, often for political or economic gain.

Examples of APT Campaigns

The Stuxnet worm, discovered in 2010, targeted Iran’s nuclear facilities and is believed to be a state-sponsored attack. The APT1 group, linked to China’s People’s Liberation Army, has been implicated in numerous cyber espionage operations against Western companies.
