This covert threat involves unauthorized access to computer systems and networks with the intent to gather sensitive information, potentially causing severe consequences. It can range from shattered corporate reputations or loss of competitive advantage to compromised national security. In this context, understanding common cyber espionage tactics is critical to implement effective countermeasures.
Business email compromise
Characterized by its deceptive simplicity, business email attacks involve impersonating a trusted individual or entity through email communication to manipulate employees, clients, or consumers into revealing sensitive information or executing fraudulent financial transactions. This can often result in substantial economic losses and reputational damage.
Credential stuffing
Threat actors use stolen usernames and passwords from one website or service to gain access to other accounts, exploiting individuals who use the same login credentials across multiple platforms. This tactic relies on reused passwords, making it an effective method to compromise accounts and access sensitive information.
Insider threat
According to IBM, attacks initiated by malicious insiders were the costliest at an average of USD 4.90 million. This is a significant cyber threat tactic wherein individuals with authorized access to an organization’s systems and data exploit their position. These individuals can be employees, contractors, or business partners.
Supply chain attacks
In these attacks, actors seek to compromise third-party vendors or suppliers to access the target organization’s systems or data. They can then undermine the security of the entire supply chain, potentially leading to data breaches, system compromises, or other adverse consequences. Proactive risk mitigation is essential to counter this multi-layered and evolving threat.
