USSD on a Sony Ericsson mobile phone (2005). Unstructured Supplementary Service Data (USSD), sometimes referred to as "quick codes" or "feature codes", is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator's computers.
A software update, sometimes referred to as a patch, can add functionalities and address flaws in existing code. [8] Unfortunately, in delivering updates to neutralize flaws, these systems can unintentionally introduce vulnerabilities that, in turn, can be exploited by attackers. [9] [10] [11]
ETSI and 3rd Generation Partnership Project (3GPP) standards, such as GSM and LTE, define supplementary service codes that make it possible to query and set certain service parameters (e.g., call forwarding) directly from mobile devices.
Security researchers with U.S. cybersecurity firm Symantec said they have discovered a “highly sophisticated” Chinese hacking tool that has been able to escape public attention for more than a ...
FinFisher can be covertly installed on targets' computers by exploiting security lapses in the update procedures of non-suspect software. [ 2 ] [ 3 ] [ 4 ] The company has been criticized by human rights organizations for selling these capabilities to repressive or non-democratic states known for monitoring and imprisoning political dissidents ...
Pipedream is a software framework for malicious code targeting programmable logic controllers (PLCs) and industrial control systems (ICS). [1] First publicly disclosed in 2022, it has been described as a "Swiss Army knife" for hacking. [1] It is believed to have been developed by state-level Advanced Persistent Threat actors. [1]
Asaf Shelly published the technique in 2017 [22] and demonstrated the use of Binary Randomization in a software update system. For every updated device, the Cloud-based service introduced variations to code, performs online compilation, and dispatched the binary.
The malicious code is known to be in 5.6.0 and 5.6.1 releases of the XZ Utils software package. The exploit remains dormant unless a specific third-party patch of the SSH server is used. Under the right circumstances this interference could potentially enable a malicious actor to break sshd authentication and gain unauthorized access to the ...
