DomainTools is tracking an increase in SMS phishing (or “smishing”) campaigns impersonating the US Postal Service (USPS). The text messages inform recipients that there’s a problem with their delivery address and they need to click on a link to resolve the issue.
“At first glance, the choice of language in the text seems suspect,” DomainTools says. “Likely adopted from another phishing script and used over in this campaign, the phrasing shows signs that it was written by someone that either has English as an additional language, or has limited proficiency and likely relied on a translation service to help craft the message. Thankfully they didn’t have the foresight to use a platform like ChatGPT to help craft the content, which could have generated a more convincing lure.”
The researchers note that attackers can use publicly available information to gather additional information about their targets in order to craft more convincing phishing attacks.
“In this case, the person of interest used the same email addresses not only to register for different services, but tied the emails together by using them as back up or secondary emails for a number of other accounts,” DomainTools says. “When these additional accounts are included, we uncover an additional 20 domains tied to the same person. When individuals don’t expect this data to come to light, they may become lax in what else they tie to these items, including social media and other accounts that are useful in expanding and adding new prospective avenues for inquiry.”
DomainTools adds, “Even though phishing and smishing campaigns have become an unfortunate daily fact of life, they remain a significant source of prospective harm for not only individuals, but the companies and organizations whose services they use. The resulting harm both from a loss perspective as well as the emotional toll on individuals, is added to the cost in time, money, and resources that companies face in defending their customers and ensuring that their brand reputation and business operations are not impacted.”
