By targeting critical infrastructure or disrupting essential services, Iran aims to exert pressure on the United States to change its policies or make concessions.

Tactics and Techniques Employed

Iranian cyber actors employ a diverse range of tactics and techniques to achieve their objectives. Phishing attacks are a common method, where deceptive emails or websites are used to trick individuals into revealing sensitive information, such as usernames, passwords, or financial details. These attacks can be highly sophisticated, using social engineering to impersonate trusted sources and lure victims into clicking malicious links or opening infected attachments. Another prevalent technique is the use of malware. Iranian hackers develop and deploy various types of malicious software, including viruses, worms, and Trojans, to infiltrate computer systems, steal data, or disrupt operations. This malware can be delivered through various channels, such as email attachments, infected websites, or compromised software updates.

Distributed denial-of-service (DDoS) attacks are also frequently employed. These attacks involve overwhelming a target server or network with a flood of traffic, rendering it inaccessible to legitimate users. DDoS attacks can be used to disrupt websites, online services, and critical infrastructure, causing significant inconvenience and financial losses. In addition, Iranian hackers have been known to engage in supply chain attacks, compromising software or hardware vendors to gain access to their customers' systems. This allows them to infiltrate a wide range of organizations through a single point of entry. The tactics used by Iranian cyber actors are constantly evolving, requiring continuous monitoring and adaptation of defense strategies.

High-Profile Examples of Iranian Cyber Attacks

Over the years, several high-profile cyber attacks have been attributed to Iranian actors, highlighting the scope and severity of this threat.
