New SIM-swap hacks highlight carriers’ wobbly security

New SIM-swap hacks highlight carriers’ wobbly security

  • Written by Martha DeGrasse/Light Reading
  • 14th January 2020

Several new studies have found that hackers can convince wireless carriers’ customer service agents to port legitimate phone numbers to bogus accounts — a practice that can then open that account up to fraud and theft.

Researchers at Princeton University called three of the four major carriers and tried to convince customer service representatives to move phone numbers to new SIM cards. Verizon, AT&T and T-Mobile each received ten calls from the researchers, who posed as customers.

Astoundingly, in all 30 cases the fake customers successfully convinced the carriers to move the numbers to new SIM cards.

When the carriers tried to authenticate the customers by texting personal identification numbers (PINs), the “customers” acted confused and said the wrong PIN numbers, because of course they had not received the texts. Then the carriers asked for other forms of authentication, like most recently called numbers and most recent payments. The researchers had done their homework and in most cases were able to answer these questions correctly.

How can researchers (and hackers) get access to a victim’s call history and payment history? By manipulating it. They can text multiple people fake offers that seem too good to refuse, until one person calls back. Now they have a recently called number. If the call happens to be from a prepaid account, the hacker has hit the jackpot because they can go to a convenience store, buy a refill card for a few dollars and then use it to refill that victim’s account. Now the hacker has payment history. The next step is to call the carrier and request a SIM swap.

  • Ransomware, data breaches inundate OT & industrial sector
    Three-quarters of industrial firms suffered a ransomware attack in the past year, with far more compromises affecting operational technology (OT) than ever before — representing a surge in attacks driven by both the industrial sector’s vulnerability and propensity to pay ransoms in order to remain operational. In the past 12 months, more than half of […]

    Lost in AT&T’s big $14 billion announcement with Ericsson for open RAN was the fact that it also plans to purchase 5G radios from Fujitsu. The move represents a major win for the Japanese wireless network equipment vendor, which is relatively unknown outside its home market. “In order to support the acceleration of open RAN in AT&T’s […]

    A Public Safety Spectrum Alliance (PSSA) filing this week reiterates its call for the FCC to award a nationwide license of 4.9 GHz  spectrum to the FirstNet Authority, ignoring a recent coalition filing that asks the commission to approve rules that would let local jurisdictions largely determine how the airwaves are used.

    Attackers can exploit a critical Bluetooth security vulnerability that’s been lurking largely unnoticed for years on macOS, iOS, Android, and Linux device platforms. The keystroke injection vulnerability allows an attacker to control the targeted device as if they were attached by a Bluetooth keyboard, performing various functions remotely depending on the endpoint. Tracked as CVE-2023-45866, the flaw exists […]
