The first worm, the Morris worm, I couldn't google quickly the language.. Maybe C, rsh shell was mentioned, but I'm not sure it was a shell language.. It was cross-platform, so maybe that is an argument in its favor. The first viruses I remember, where boot-sector viruses, so you had less than bytes, then I assume x86 () assembly language Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device.. On ordinary (non-WORM) data storage devices, the number of times data can be modified is limited only by the lifespan of the device, as Only Java prohibited writing of viruses. In all other languages, you can write a virus. For writing a virus in C follow the following. Steps: 1. Learn C and assembly. 2. Think how your virus work. 3. Write your own virus. If you can't write, go back to first step
How do I create a computer virus?
Our goals:. With these seven simple principles, we started our work. This text describes our ideas, concepts and implementation issues. Code provided here is partial, often comes from first, instead of most recent, Samhain release and so on.
But remember — working model has been written. And this model is deadly dangerous engine, which can be used to very, very bad things. The task is quite easy to complete if you decide to spread your code in platform-independent form.
How could it be achieved? What can we do? Using wormnet, worm during infection might ask other wormnet members for compiled binary for given platform. Wormnet details have been described in section 0x Anyway, binary will contain appended source code, to make futher infections possible within standard procedure. Infection scheme is described in section 0x Also, this constant decryptor has been every time re-written using simple polymorphic engine see section 0x06 to avoid constant strings.
Later, we modified encryption routine to something little bit stronger based on logistic equation number generator in chaotical window — in fact, it only makes it more difficult to detect in inactive form. NOTE: For writing extremely ugly code best language to write a worm can run in DOS, [ba]sh, csh, perl etc and can be compiled with C in the same time, please refer IOCCC archives [2]. It does cross-partition infections and installs itself as compiler trojan modifying include files to put evil instructions in every compiled source.
It is called Califax and has been developed while writting Samhain, as an excercise to prove that such cross-system jumps are possible. Of course, at first we should avoid such attempts by camouflage. This comment comes from libworm README for Unices:. You should use them before fork ing:. Lifetime should be set to something about microseconds. Return values: 0 — no anti-worm stuff detected, please use ascan or wscan.
Results are more accurate: 0 — no anti-worm stuff detected you might use wscan 1 — anti-worm stuff in operation. Return values: 0 — no anti-worm stuff detected 1 — anti-worm stuff in operation.
This is aletrnative version of forkdesigned to fool dumb anti-worm software use it when bscan returns 1. Return value: similar as for fork. PID will be NOT changed.
Return value: non-zero on error. Note: variables, best language to write a worm, stack and anything else will be reset. Please use other way pipes, files, filenames, process name to transfer data from old to new executable. Pass argv[0] as parameter.
For more details and source code on architecture-independent non-root process hiding techniques, please refer libworm sources [3] incomplete for now, but always something. This routines are weak and might be used only for short-term process hiding. We should as best language to write a worm as possible gain root access again, this aspect will be discussed later, best language to write a worm.
Then, we have probably the most complex aspect of whole worm. Advanced process hiding is highly system-dependent, usually done by intercepting system calls. We have developed source for universal hiding modules on some systems, but it not working on every platform Samhain might attack.
Techniques used there are based on well-known kernel file and process hiding modules. Our Linux 2. Sebastian wrote stealth file techniques to return original contents of eventually infected fileswhile I developed process hiding and worm interface.
Module intercepted open, lseek, llseek, mmap, fstat, stat, lstat, kill, ptrace, close, read, unlink, write and execve calls. In this case, we wanted to skip samhain code loader at the beginning of file. Process hiding is quite generic:. Similar code has been written for some other platforms. The magic word. Wormnet is used to distribute upgraded Samhain modules eg. new exploit pluginsand to query other worms for compiled binaries.
Connections are persistent. We have four types of requests:. Wormnet connections structure looks arbitrary and is limited only by max per-worm connections limit, best language to write a worm.
Connections are initiated from child to parent worm, usually bypassing firewall and masquerading software. If parent has too many wormnet connections at time, and refuses new connection, child should connect to worm from the history list. What about exploits? Exploits are modular plugged into worm bodyand divided in two sections — local and remote. We wanted to be platform independent, so we focused on filesystem races, bugs like -xkbdir hole in Xwindows, best language to write a worm, and inserted just a few buffer overflows, mainly for remote intrusion but best language to write a worm decided to incorporate some bugs like remote pine mailcap exploit and so on… Code was kind of shell-quoting masterpiece.
Pine mailcap exploit it has been already fixed after my BUGTRAQ post, but in late it was something new and nice :. Message body contained code to be executed shell-script to connect, download and run worm, then kill any evidence. Yes, this exploit sucks — as it required some kind of user interaction reading e-mailbut is just an example. Both remote and local exploits are sorted by effectiveness. Exploits that succed most of the time are tried first.
Less effective ones are moved at the end. This list is inherited by child worms. Oh, spreading. Victims are choosen by monitoring active network connections. With random probability, servers are picked from this list and attacked.
In case of failure, server is not attacked until new version of best language to write a worm is uploaded.
Four things:. This is one of them:. As I told before, worm modules were signed. First, using simple signatures, then using simple private best language to write a worm signing not really difficult to crack, as key was relatively short, but for sure too difficult for amateurs. Polymorphic engine was quite simple — designed to make sure our decryptor will be different every time. What happened to it? I stopped developing new code and testing it best language to write a worm January,with Samhain 2, best language to write a worm.
Then, we removed our repository from networked server we used to exchange ideas. I gradually published some bugs used in exploit database to BUGTRAQ, some of them especially those not discovered by me we kept for ourselves. computer-securitydarknetmalwareProgrammingviriivirusvirusesworms, best language to write a worm.
