Image: Shutterstock.com Three different cybercriminal groups claimed access to internal networks at communications giant T-Mobile in more than 100 separate incidents throughout 2022, new data suggests. In each case, the goal of the attackers was the same: Phish T-Mobile employees for access to internal company tools, and then convert that access into a cybercrime service that could be hired to divert any T-Mobile user’s text messages and phone calls to another device. The conclusions above are based on an extensive analysis of Telegram chat logs from three distinct cybercrime groups or actors that have been identified by security researchers as particularly active in and effective at “SIM-swapping,” which involves temporarily seizing control over a target’s mobile phone number. Countless websites and online services use SMS text messages for both password…

Web hosting giant GoDaddy made headlines this month when it disclosed that a multi-year breach allowed intruders to steal company source code, siphon customer and employee login credentials, and foist malware on customer websites. Media coverage understandably focused on GoDaddy’s admission that it suffered three different cyberattacks over as many years at the hands of the same hacking group.  But it’s worth revisiting how this group typically got in to targeted companies: By calling employees and tricking them into navigating to a phishing website. In a filing with the U.S. Securities and Exchange Commission (SEC), GoDaddy said it determined that the same “sophisticated threat actor group” was responsible for three separate intrusions, including: -March 2020: A spear-phishing attack on a GoDaddy employee compromised the hosting login credentials of approximately 28,000…

A security firm has discovered that a six-year-old crafty botnet known as Mylobot appears to be powering a residential proxy service called BHProxies, which offers paying customers the ability to route their web traffic anonymously through compromised computers. Here’s a closer look at Mylobot, and a deep dive into who may be responsible for operating the BHProxies service. The BHProxies website. First identified in 2017 by the security firm Deep Instinct, Mylobot employs a number of fairly sophisticated methods to remain undetected on infected hosts, such as running exclusively in the computer’s temporary memory, and waiting 14 days before attempting to contact the botnet’s command and control servers. Last year, researchers at Minerva Labs spotted the botnet being used to blast out sextortion scams. But according to a new report…

Posted by Eugene Liderman, Director of Mobile Security Strategy, Google As Mobile World Congress approaches, we have the opportunity to have deep and meaningful conversations across the industry about the present and future of connected device security. Ahead of the event, we wanted to take a moment to recognize and share additional details on the notable progress being made to form harmonized connected device security standards and certification initiatives that provide users with better transparency about how their sensitive data is protected. Supporting the GSMA Working Party for Mobile Device Security Transparency We’re pleased to support and participate in the recently announced GSMA working party, which will develop a first-of-its-kind smartphone security certification program. The program will leverage the Consumer Mobile Device Protection Profile (CMD PP) specification released by ETSI,…

Posted by Roger Piqueras Jover, Ivan Lozano, Sudhi Herle, and Stephan Somogyi, Android Team A modern Android powered smartphone is a complex hardware device: Android OS runs on a multi-core CPU - also called an Application Processor (AP). And the AP is one of many such processors of a System On Chip (SoC). Other processors on the SoC perform various specialized tasks — such as security functions, image & video processing, and most importantly cellular communications. The processor performing cellular communications is often referred to as the baseband. For the purposes of this blog, we refer to the software that runs on all these other processors as “Firmware”. Securing the Android Platform requires going beyond the confines of the Application Processor (AP). Android’s defense-in-depth strategy also applies to the firmware…

Millions of Americans receiving food assistance benefits just earned a new right that they can’t yet enforce: The right to be reimbursed if funds on their Electronic Benefit Transfer (EBT) cards are stolen by card skimming devices secretly installed at cash machines and grocery store checkout lanes. On December 29, 2022, President Biden signed into law the Consolidated Appropriations Act of 2023, which — for the first time ever — includes provisions for the replacement of stolen EBT benefits. This is a big deal because in 2022, organized crime groups began massively targeting EBT accounts — often emptying affected accounts at ATMs immediately after the states disperse funds each month. EBT cards can be used along with a personal identification number (PIN) to pay for goods at participating stores, and…

Microsoft is sending the world a whole bunch of love today, in the form of patches to plug dozens of security holes in its Windows operating systems and other software. This year’s special Valentine’s Day Patch Tuesday includes fixes for a whopping three different “zero-day” vulnerabilities that are already being used in active attacks. Microsoft’s security advisories are somewhat sparse with details about the zero-day bugs. Redmond flags CVE-2023-23376 as an “Important” elevation of privilege vulnerability in the Windows Common Log File System Driver, which is present in Windows 10 and 11 systems, as well as many server versions of Windows. “Sadly, there’s just a little solid information about this privilege escalation,” said Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative. “Microsoft does note that the…

Posted by Kent Walker, President, Global Affairs & Chief Legal Officer, Google & Alphabet and Royal Hansen, Vice President of Engineering for Privacy, Safety, and Security Should companies be responsible for cyberattacks? The U.S. government thinks so – and frankly, we agree. Jen Easterly and Eric Goldstein of the Cybersecurity and Infrastructure Security Agency at the Department of Homeland Security planted a flag in the sand: “The incentives for developing and selling technology have eclipsed customer safety in importance. […] Americans…have unwittingly come to accept that it is normal for new software and devices to be indefensible by design. They accept products that are released to market with dozens, hundreds, or even thousands of defects. They accept that the cybersecurity burden falls disproportionately on consumers and small organizations, which are…
