More SIM Cards Vulnerable to Simjacker Attack Than Previously Disclosed

More SIM Cards Vulnerable to Simjacker Attack Than Previously Disclosed

Sep 27, 2019
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
Vodafone Germany rolls out SIM Card-based end-to-end Encryption

Vodafone Germany rolls out SIM Card-based end-to-end Encryption

Mar 11, 2014
Since mobile has become a basic need for every common as well as important figure now a days. So, every company is highly working to find more effective ways to protect sensitive data of their users and in the race, Vodafone lead the game. In collaboration with its security partner Giesecke & Devrient ( G&D ) which is an international leader in mobile security solutions, Vodafone is offering an end-to-end encryption for mobile communication based on the phone SIM card. Secure Data such as emails, documents, data carriers, and VPN connections will be signed and encrypted by the SIM in such a way that they are unreadable to unauthorized third parties assuring your security and privacy. SIM users have to encrypt the data by simply using a PIN and a digital signature, and the same is needed in order to decrypt the communication. " The solution uses the widespread S/MIME encryption program for email exchanges, and in the future, encryption via PGP will also be
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
