Slashdot: Carrier Caught Injecting 'SMS AD' Into Google Verification Code Message

Carrier Caught Injecting 'SMS AD' Into Google Verification Code Message
Published on July 01, 2021 at 03:32AM
An anonymous reader quotes a report from 9to5Google: SMS is widely regarded as an insecure form of two-factor authentication, and another example of this has just emerged. A carrier looks to be injecting ads into the Google verification code used to sign in to services like Gmail. Action Launcher developer Chris Lacy today tweeted how his Google verification code -- which starts with "G-" -- featured an "SMS AD." The advertisement -- for a VPN -- includes a quick message and short URL. For those that immediately suspect this is just a phishing attempt, the verification code is legitimate and was requested by Lacy to successfully verify a login attempt. Google Messages even flagged the link/message as spam. As such, Googlers responding to the thread suspect this is an occurrence of a carrier appending an ad -- note the extra spaces -- into a real text message. It's very unlikely that Google's security teams would allow advertising into a very crucial part of the login process where end user trust is paramount. Google issued the following statement to us today: "These are not our ads and we are currently working with the wireless carrier to understand why this happened." Google confirms that the "SMS AD" did not originate from its own advertising network. Meanwhile, it's working with the wireless carrier in question to find out what occurred. Lacy has decided "not to state the carrier for privacy reasons," and Google did not share that information either.

Slashdot: US Army Soldier Arrested In AT&T, Verizon Extortions

US Army Soldier Arrested In AT&T, Verizon Extortions Published on January 01, 2025 at 02:35AM An anonymous reader quotes a report from KrebsOnSecurity: Federal authorities have arrested and indicted a 20-year-old U.S. Army soldier on suspicion of being Kiberphant0m, a cybercriminal who has been selling and leaking sensitive customer call records stolen earlier this year from AT&T and Verizon. As first reported by KrebsOnSecurity last month, the accused is a communications specialist who was recently stationed in South Korea. Cameron John Wagenius was arrested near the Army base in Fort Hood, Texas on Dec. 20, after being indicted on two criminal counts of unlawful transfer of confidential phone records. The sparse, two-page indictment (PDF) doesn't reference specific victims or hacking activity, nor does it include any personal details about the accused. But a conversation with Wagenius' mother -- Minnesota native Alicia Roen -- filled in the gaps. Roen said that prio...

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.
