![]() So, the developers finally decided to migrate the PHP source code to the repository on GitHub for several security reasons. However, the security experts at the PHP team is investigating the whole matter closely, and experts state that the malicious change was a hacked server, not a hacked individual user’s Git account.Īccording to the internal reports, the changes affected the development branches for PHP 8.1, which is scheduled for release later this year. And the changes were clearly malicious and were immediately reversed. ![]() The first commit was discovered a couple of hours after its implementation during a routine code review. This line executed PHP code from the user’s HTTP header if the line began with ‘zerodium’, explained by Jake Birchall, a PHP developer. If this version of PHP runs on a server, an attacker can execute arbitrary code by sending the User-Agentt header. Read More Here This script will let you easily connect to this backdoor and execute commands on the machine. The added line 370, where the zend_eval_string function is called, contained the code that actually injected a backdoor to remotely execute code on a website running an infected version of the PHP. Python based backdoor exploit script for PHP/8.1.0-dev Description: On the 28th of March 2021 a backdoor was placed within PHP version 8.1.0-dev. In fact, they changed the PHP source code to implement a remotely managed backdoor. The hackers tried to hide their malicious activity and passed off the implemented changes as simple typographical fixes. The threat actors added commits hidden as PHP developers Rasmus Lerdorf and Nikita Popov. The cybercriminals have recently hacked into the official PHP Git repository in order to inject two malicious secret backdoors into the source code and change the codebase. That these snapshot builds are not recommended for production.Hackers Hacked PHP Git Repository to Inject Secret Backdoor Into Source Code If there is no snapshot for your package available,Īnd to request that a snapshot for that package is being build. Waiting for two months is no option for you? In that case you can download After the builds have been done, you canĭownload the binary packages from PECL packages that is, after PHP 8.1.2 has been released, what is currently Late January or early February to trigger the mass build for all applicable Provide possibly premature binary packages, so as usual, we will wait until Well, the PHP for Windows team does not want to This happens if the parameters are configurable by an attacker for instance by providing the output of scryptenc() in a context where Hack/PHP code would. See the manual for details.Īnd you may be eager to try it out, but you need one or more PECL packagesįor which there are no PHP 8.1 binary packages available yet, and you may wonder when X64 builds are recommended (almost all Windows installations support 圆4). ![]() ![]() The 圆4 builds of PHP 7 support native 64-bit integers, LFS, 64-bit memory_limit and much more. PHP PGO build for maximum performance (old).Profile Guided Optimization is an optimizationįeature available in Microsoft's Visual C++ compiler that allows you to optimize an output file based on profiling data collected during test runs of the application or module. The FastCGI protocol, utilizing no multithreading (but also for example CLI). For NTS binaries the widespread use case is interaction with a web server through Use case for TS binaries involves interaction withĪ multithreaded SAPI and PHP loaded as a module into a web server. The VC15 and VS16 builds require to have the Visual C++ Redistributable for Visual Studio 2015-2019 圆4 or x86 installed TS and NTS Include improvements in performance and stability. More recent versions of PHP are built with VC15 or VS16 (Visual Studio 2017 or 2019 compiler respectively) and With Apache, using the apache2handler SAPI, you have to use the Thread Safe (TS) versions of PHP. We use their binaries to build the Apache SAPIs. They provide VC15 and VS16 builds of Apache for x86 and 圆4. Please use the Apache builds provided by Apache Lounge. If you are using PHP as FastCGI with IIS you should use the Non-Thread Safe (NTS) versions of PHP.
