Today, we are rightfully concerned about security breaches and our lives online. If you’re a Verizon subscriber, you may have noticed some suspicious activity on your account. The company has informed customers that it suffered a security breach that resulted in some SIM swapping.
According to the company, an unauthorized third party gained access to the last four digits of several people’s credit/debit cards. Although his payment information is not compromised, that third party may have used those four digits to gain access to his Verizon account and process a SIM card change. If a SIM swap occurred, Verizon should have already reversed it.
Verizon said it has monitored the activity of affected users and found no evidence that malicious activity is still ongoing, or that the attackers have gained access to personal information such as SSNs, full credit card numbers, tax IDs, or other information. . The carrier also reset a number of PINs as a precaution.
Verizon’s notification might have been late for some people. According to a Verizon subscriber speaking with computer beepfell victim to a SIM swap attack a week before Verizon alerted anyone, and the attackers tried to access their cryptocurrency wallet on Coinbase.
However, as of this writing, your account shouldn’t be compromised, and if you suffered a SIM swap attack, it should have been reversed by Verizon by now. But recent security breaches have affected everyone from Samsung, DoorDash, Plex, or even LastPass, so you should double down on your online security, even if you haven’t run into any nasty issues.
