In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". [ b ] [ 4 ] The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution through OpenSSH on the affected Linux system.
February 8: Foxconn is hacked by a hacker group, "Swagg Security", releasing a massive amount of data including email and server logins, and even more alarming—bank account credentials of large companies like Apple and Microsoft. Swagg Security stages the attack just as a Foxconn protest ignites against terrible working conditions in southern ...
Typical resource leaks include memory leak and handle leak, particularly file handle leaks, though memory is often considered separately from other resources. [1] Examples of resources available in limited numbers to the operating system include internet sockets, file handles, process table entries, and process identifiers (PIDs). Resource ...
A DDoSecrets server hosting BlueLeaks data for public download was located in Germany, and German authorities seized it at the request of the United States. DDoSecrets co-founder Emma Best reported that it was the group's "primary public download server". [44] [45] [46] After the leak, Twitter suspended DDoSecrets' account.
Code injection is a computer security exploit where a program fails to correctly process external data, such as user input, causing it to interpret the data as executable commands. An attacker using this method "injects" code into the program while it is running.
In programming and software development, fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks. Typically, fuzzers are ...

Another example is the key leakage that can occur when using some public-key systems when cryptographic nonce values used in signing operations are insufficiently random. [2] Bad randomness cannot protect proper functioning of a cryptographic system, even in a benign circumstance, it can easily produce crackable keys that cause key leakage.
