SIM Cards in 29 Countries Vulnerable to Remote Simjacker Attacks

SIM Cards in 29 Countries Vulnerable to Remote Simjacker Attacks

Oct 12, 2019
Until now, I'm sure you all might have heard of the SimJacker vulnerability disclosed exactly a month ago that affects a wide range of SIM cards and can remotely be exploited to hack into any mobile phone just by sending a specially crafted binary SMS. If you are unaware, the name "SimJacker" has been given to a class of vulnerabilities that resides due to a lack of authentication and proprietary security mechanisms implemented by dynamic SIM toolkits that come embedded in modern SIM cards. Out of many, two such widely used SIM toolkits — S@T Browser technology and Wireless Internet Browser (WIB) — have yet been found vulnerable to SimJacker attacks, details of which we have provided in our previous articles published last month. At that time, a few experts in the telecom industry confirmed The Hacker News that the SimJacker related weaknesses were internally known to many for years, and even researchers also revealed that an unnamed surveillance company has been

Remember the Simjacker vulnerability? Earlier this month, we reported about a critical unpatched weakness in a wide range of SIM cards, which an unnamed surveillance company has actively been exploiting in the wild to remotely compromise targeted mobile phones just by sending a specially crafted SMS to their phone numbers. If you can recall, the Simjacker vulnerability resides in a dynamic SIM toolkit, called the S@T Browser , which comes installed on a variety of SIM cards, including eSIM, provided by mobile operators in at least 30 countries. Now, it turns out that the S@T Browser is not the only dynamic SIM toolkit that contains the Simjacker issue which can be exploited remotely from any part of the world without any authorization—regardless of which handsets or mobile operating systems victims are using. WIB SIM ToolKit Also Leads To SimJacker Attacks Following the Simjacker revelation, Lakatos, a researcher at Ginno Security Lab, reached out to The Hacker News earli

How to Handle Retail SaaS Security on Cyber Monday

How to Handle Retail SaaS Security on Cyber Monday

Nov 27, 2023SaaS Security / Cyber Monday
If forecasters are right, over the course of today, consumers will spend  $13.7 billion . Just about every click, sale, and engagement will be captured by a CRM platform. Inventory applications will trigger automated re-orders; communication tools will send automated email and text messages confirming sales and sharing shipping information.  SaaS applications supporting retail efforts will host nearly all of this behind-the-scenes activity. While retailers are rightfully focused on sales during this time of year, they need to ensure that the SaaS apps supporting their business operations are secure. No one wants a repeat of one of the biggest retail cyber-snafus in history, like when one U.S.-based national retailer had 40 million credit card records stolen.  The attack surface is vast and retailers must remain vigilant in protecting their entire SaaS app stack. For example, many often use multiple instances of the same application. They may use a different Salesforce tenant for eve
New SIM Card Flaw Lets Hackers Hijack Any Phone Just By Sending SMS

New SIM Card Flaw Lets Hackers Hijack Any Phone Just By Sending SMS

Sep 12, 2019
Cybersecurity researchers today revealed the existence of a new and previously undetected critical vulnerability in SIM cards that could allow remote attackers to compromise targeted mobile phones and spy on victims just by sending an SMS. Dubbed " SimJacker ," the vulnerability resides in a particular piece of software, called the S@T Browser (a dynamic SIM toolkit), embedded on most SIM cards that is widely being used by mobile operators in at least 30 countries and can be exploited regardless of which handsets victims are using. What's worrisome? A specific private company that works with governments is actively exploiting the SimJacker vulnerability from at least the last two years to conduct targeted surveillance on mobile phone users across several countries. S@T Browser , short for SIMalliance Toolbox Browser, is an application that comes installed on a variety of SIM cards, including eSIM, as part of SIM Tool Kit (STK) and has been designed to let mobile
