According to recent findings by DomainTools researchers, there has been a significant increase in cyber-attacks targeting the US Postal Service (USPS) through phishing and smishing campaigns. As a result, the researchers decided to investigate the origins and implications of these attacks, publishing their findings in an advisory on Thursday.

One particular smishing message caught the researchers’ attention due to its unusual language, suggesting that it may have been authored by a non-native English speaker or someone relying on translation services. This sparked further investigation which led the researchers to a domain marked with a high-risk score. Upon delving deeper, they discovered 163 related domains associated with email addresses that followed a familiar naming convention.

Intriguingly, the researchers stumbled upon a Facebook account connected to one of these email addresses, which provided some insight into the potential identity of the threat actor. It is believed that the individual behind the smishing campaign is a suspected Iranian national residing and working in Tehran. This aligns with the initial suspicion that the campaign’s lure text was likely not written by a native English speaker.

The DomainTools research highlights the ongoing and persistent threat posed by phishing and smishing campaigns, emphasizing the impact they have on both individuals and organizations. The advisory warns that these campaigns not only cause financial and emotional harm to individuals, but they also impose costs on companies in terms of time, money, and resources needed to defend their customers and protect their brand reputation and business operations.

Furthermore, the security firm stresses the importance of swiftly and comprehensively identifying the infrastructure and individuals behind these campaigns. This is crucial for cybersecurity entities and law enforcement agencies in minimizing the harm caused by these criminal acts and prosecuting those responsible.

Phishing and smishing campaigns have become a daily reality, posing significant risks to individuals and organizations alike. These campaigns exploit the trust and reliance people and businesses have on email and other communication channels. By impersonating legitimate entities, such as the USPS, cybercriminals attempt to deceive recipients into divulging sensitive information or clicking on malicious links.

The USPS is one of many organizations that have fallen victim to these types of attacks. Cybercriminals continue to evolve their tactics, making it more challenging to differentiate between genuine and fraudulent communications. This underscores the need for individuals and organizations to remain vigilant and adopt proactive cybersecurity measures.

Individuals should be cautious when receiving messages, especially those requesting personal information or financial details. It is essential to verify the legitimacy of the sender and the content before taking any action. Organizations, on the other hand, should invest in robust cybersecurity solutions and educate their employees about the potential risks and best practices for identifying and responding to phishing and smishing attempts.

In conclusion, the recent surge in cyber-attacks targeting the USPS through phishing and smishing campaigns has raised concern among cybersecurity researchers. The discovery of a suspected Iranian national behind one of these campaigns highlights the global nature of cyber threats and the need for international cooperation to combat them. It serves as a reminder of the ongoing challenges posed by phishing and smishing attacks and the importance of proactive cybersecurity measures.
