Simjacker APK для Android скачать бесплатно

The Simjacker Apk vulnerability is currently being actively exploited by a certain private company that works with the government to monitor people. It and related exploits represent a huge leap in sophistication and sophistication over previously seen mobile core network attacks.

We are announcing the existence of a Simjacker vulnerability and an associated exploit. We suspect that a highly skilled attacker has been exploiting this vulnerability for at least two years, primarily for surveillance purposes. In addition to the impact on its victims,

our investigation shows that Simjacker and related exploits appear significantly more sophisticated and sophisticated than previous attacks on mobile core networks. This represents a significant increase in the skills and abilities of attackers attempting to exploit mobile networks.

We'll learn more about Simjacker technical capabilities at the Virus Bulletin conference in London on October 3, but in this blog, we'll look at how the attack works, how it works, who can benefit from it, And why is. event A very important new type of attack.

About Simjacker Apk

AdaptiveMobile Security has announced a new, previously unknown vulnerability called Simjacker Apk and a related exploit. This vulnerability is currently being actively exploited by a private company that works with the government to monitor people.

Simjacker and related exploits represent a huge leap in sophistication and sophistication over previously seen mobile core network attacks. It main attack consists of an SMS that sends a specific spyware-like code to a mobile phone, which then reads the SIM card in the phone.

To "take over" the mobile phone and execute, reset and execute sensitive commands. Location information has been obtained from thousands of devices over time without the knowledge or consent of affected mobile phone users.

During the attack, the user does not even realize that he has been attacked, the information is obtained and successfully acquitted. However, Simjacker Apk can attack and has been further upgraded to perform additional attack types.

Simjacker attacks

The attack begins with a text message containing a series of instructions for the Simjacker Apk. Following these instructions, the SIM card asks the mobile phone for the serial number and cell ID of the base station in whose coverage area the customer is located and sends an SMS reply with this information to the attacker's number.

The coordinates of the base station are known (and also available online), so using Cell ID the subscriber's location can be determined with an accuracy of several hundred meters. Location-based services generally use the same principle to determine your location without satellite support, e.g. B. Indoors or when GPS is turned off.

Any tampering with a compromised Simjacker is completely invisible to the user. SMS messages containing commands or replies to messages containing device location data do not appear on the app, so Simjacker victims do not even know they are being spied on.

How can a user prevent Simjacker attacks?

Unfortunately, there is no specific way for users to prevent Simjacker Apk. It is the duty of mobile operators to ensure the security of their customers. Most importantly, they avoid using the old SIM menu application and block SMS codes containing malicious commands.

But there is good news. While the attack doesn't require expensive hardware, it does require deep technical knowledge and specialized skills, which means the method is unlikely to be used by every cybercriminal and their dog.

In addition, the researchers notified the developer of the S@T browser, About the vulnerability. In response, the company has released a set of security guidelines for operators using the app. Simjacker also been reported to the GSM Association, an international organization representing the interests of mobile operators worldwide. So companies should take all necessary security measures as soon as possible.

What information does a Simjacker attack steal?

What data caught the attention of Simjacker Apk and his team of cybercriminals?

This gives cyber attack groups access to information such as:

• geographical location;
• user language;
• battery level;
• Email account

Know the connection between multiple devices (all communication via email, messaging, and WhatsApp).

Simjacker App is not only capable of stealing data from your mobile device, but this attack allows your smartphone to perform certain actions without you noticing. Your phone has been accidentally shaken:

• Send viral SMS with your phone number
• Start unofficial international calls
• Denial of service attacks
• Spread malware

A set of Simjacker vulnerabilities and attacks

Simjacker are also used for many other types of attacks such as scams, fraudulent calls, information leaks, denial of service, and chats against individuals and mobile operators.

Analysts at Adaptive Mobile Security Threat Intelligence observed that hackers varied their attacks and performed many of these exploits. In theory, all cell phone brands and models are vulnerable to attack because the vulnerability is related to the technology embedded in the SIM card.

The Simjacker vulnerability could spread to more than a billion mobile phone users worldwide, potentially affecting the Americas, West Africa, Europe, the Middle East, and all regions of the world where this technology is used for SIM cards.

Prevent attacks and build long-term security

We are pretty sure this exploit was developed by an elite private company working with the government to monitor people.

Adaptive Mobile Security works closely with its customers and the industry at large; Involves both mobile network operators and SIM card manufacturers in protecting mobile subscribers. We have stopped the attacks and are committed to using our global threat intelligence to defend against these new and sophisticated attacks that bypass existing security measures.

How does this work?

In its simplest form, a Simjacker main attack involves sending an SMS containing a specific spyware-like code to a mobile phone, causing the UICC (SIM card) in the phone to "take control" of the mobile phone. . Gives instructions. Retrieve and execute sensitive orders.

The attack begins when an SMS – what we at SimJacker call an “attack message” – is sent to the target phone. This Simjacker attack message, sent from an SMS sender account associated with another phone, GSM modem, or A2P account, contains a set of SIM Toolkit (STK) instructions and specifically the UICC/EUICC (SIM). Designed for use by. card) in the device.

To execute these instructions, the attacker exploits the presence of special software called S@T Browser on the UICC. It uses the S@T Browser library on the UICC as an execution environment where it can execute logic on the phone. In the main attack observed, the Simjacker code running on UICC requests location and unique device information (IMEI) from the phone.

Once this information is received, the Simjacker code running on the UICC combines it and sends the combined information via another SMS (we call it a "data message") to the recipient's number and the combined activation logic' comes back to This data message is a method that can be used to extract location and IMEI information on an attacker-controlled remote phone.
