Background for this topic.
Source code is the human-readable text programmers write in a language such as Python, Java, or C before it is compiled or interpreted into a running program. It defines the program’s logic, data handling, and interactions with operating systems, networks, and other services. Source code may include application code, scripts, and configuration that controls software behavior.
In security, exposed or improperly protected repositories can disclose credentials, private keys, internal endpoints, or details that help attackers find exploitable flaws. Vulnerabilities may also enter through unsafe coding patterns, outdated dependencies, or malicious changes to code and build pipelines. Defenses include least-privilege repository access, secret scanning, peer review, static analysis, dependency and software-composition checks, and integrity controls for releases. Preserving commit history and build provenance helps investigators determine what changed and whether delivered software matches reviewed source.
1.5TB of databases, source code, BIOS tools said to be stolen Owners of MSI-brand motherboards, GPUs, notebooks, PCs, and other equipment should exercise caution when updating their device's firmware or BIOS after the manufacturer revealed it has recently suffered a cyberattack.…
Plus: Substack shanked by bitter Twitter? The chunk of internal source code Twitter released the other week contains a "shadow ban" vulnerability serious enough to earn its own CVE, as it can be exploited to bury someone's account of sight "without recourse."…
Less than a month ago, Twitter indirectly acknowledged that some of its source code had been leaked on the code-sharing platform GitHub by sending a copyright infringement notice to take down the incriminated repository. The latter is now inaccessible, but according to the media, it was accessible to the public for several months. A user going by the name FreeSpeechEnthousiast committed
Taiwanese PC parts maker MSI (Micro-Star International) has been listed on the extortion portal of a new ransomware gang known as "Money Message," which claims to have stolen source code from the company's network. [...]
