Slashdot: Small Study Finds Computer Repair Shops Accessed Personal Data - And Sometimes Even Copied It

Small Study Finds Computer Repair Shops Accessed Personal Data - And Sometimes Even Copied It
Published on November 28, 2022 at 02:43AM
Ars Technica reports on what happened when researchers at the University of Guelph in Ontario, Canada, left laptops overnight at 12 computer repair shops — and then recovered logs after receiving their repairs: The logs showed that technicians from six of the locations had accessed personal data and that two of those shops also copied data onto a personal device.... The amount of snooping may actually have been higher than recorded in the study, which was conducted from October to December 2021. In all, the researchers took the laptops to 16 shops in the greater Ontario region. Logs on devices from two of those visits weren't recoverable. Two of the repairs were performed on the spot and in the customer's presence, so the technician had no opportunity to surreptitiously view personal data. In three cases, Windows Quick Access or Recently Accessed Files had been deleted in what the researchers suspect was an attempt by the snooping technician to cover their tracks.... The vast majority of repair shops provide no privacy policy and those that do have no means of enforcing them. Even worse, repair technicians required a customer to surrender their login password even when it wasn't necessary for the repair needed. These findings came from a separate part of the study, in which the researchers brought an Asus UX330U laptop into 11 shops for a battery replacement. This repair doesn't require a technician to log in to the machine, since the removal of the back of the device and access to the device BIOS (for checking battery health) is all that's needed. Despite this, all but one of the repair service providers asked for the credentials to the device OS anyway. When the customer asked if they could get the repair without providing the password, three refused to take the device without it, four agreed to take it but warned they wouldn't be able to verify their work or be responsible for it, one asked the customer to remove the password, and one said they would reset the device if it was required.

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.
