2024-04-01: Now when you use the shlog as the shell for an account, the shlog will use the first shell found from /etc/shells and recording the whole login session.

2024-03-22: Our ssh_rundirect is now updated with the new capabilities to not only control the max size of file creation and set the required mask in the jail environment but also global environment. Also now you can set the account so that it can get different supplementary groups in global and jail environments, very flexible.

2024-02-24: Our WZSysGuard now can reliably detect long runing SetUID process, this will greatly help to detect possible back doors when your system got hacked.

2023-11-20: We have updated fcrypt package again. The new version will allow apps that generate top secret info can pass the secret info through pipe to our auto-encryption tool to get encrypted immediately.

2023-08-15: We have now released version 3.1 for fcrypt package. The new version fixed a possible issue that attackers could use to steal the info that should be protected.

2023-06-18: We have now further enhanced the anti-hacking capabilities of AutoSSH and AutoSFTP, making statically analyzing the codes harder, so the encrypted passphrase protection is now even better.

2023-02-20: The gencert program in our WZSysGuard software now has an improvement that will allow multiple commands to be certified and registered at once to save the trouble to need to enter WZSysGuard passprase and 2 times of checksum protection passphrase for each command's certification registration.

2022-12-20: Our WZSysGuard software now provides a daemon program that can help the system to combat many of the software-based attacks, such as dtrace, probevue, systemtap, bpftrace, uprobe, kprobe, or the memory snoopers that open the /dev/mem, /dev/kmem, /proc/kcore. It will still allow users to use strace/truss/gdb kind of tools to debug programs, and for a program that users want to prevent other to use the strace/truss/gdb kind of tools to steal info from the program, they can use the gencert/secrun/setit to protect the program.

2022-11-17: Our WZSysGuard software now provides 3 sample scripts for commands portection: once users run our gencert for a need-be-protected command, they can now just link from one of the 3 scripts to the same command name under /usr/scmd, and put /usr/scmd in the front of the PATH value, then our software can provide just Trojan Horse prevention protection with the p1cmd linked commands, provide additional 10 seconds anti-software-based password stealing attacks for the commands linked with the p10cmd, and provide process life time anti-software-based attacks for commands linked with the p0cmd.

2022-08-28: Our software now uses the sha2 384bits to encrpt the software password. And our privilege delegation software CaclMgr now can combat super user to manually modify any user's PD DB to bypass proper delegation by the ower.

2022-08-22: Our fcrypt software now offers a pair of file encryption automation tools for app to auto-encrypt the important and sensitive file immediately after it's generated without human intervention and it will only allow the accounts that have got privilege delegation from the file owner to decrypt the file without need to know the encryption key, and purely depends on the privilege delegation and authentication of privilege delegation.

2022-08-14: Our Linux verion of WZSysGuard software has been updated to make it compatible with Windows 10/11's WSL/WSL2 environment, but we found if the Linux is Ubuntu 18.04, it still has a compatible issue, running wzsgreg and wzsgchk could cause 18.04 panic the Windows PC.

The result program is a binary program, has the same functionality, but can't be debugged or traced by gdb or truss/tusc/strace; script program once converted will not be visible, you can no longer use something similar to "bash -x program" to see its execution steps. The converted program will have the most completed anti software-based attacks capabilities added. Almost all types of command that can directly run on Linux/Solaris/AIX can be converted, except those programs that will use child process to run the main functions. For those need child process to do the functions, you will need our WZSysGuard's secit to provide the protections for those commands.

2021-10-31: Our Linux security software are now grouped in to NOFA and FAOK classes, those with NOFA tag ones will find and kill any processes that use fanotify, to avoid critical file change got hidden; for those need fanotify function you need to find and use FAOK class of software, if you can't find that for the platform, then you either need to stop use the software which need the fanotify or stop use our software.

2021-08-15: Our wzshSDK and wzshRUN 6.0 now released. With encrypted script runs with wzshRUN 6.0, those hidden info stealing threats will be minimized: dtrace, systemtap, uprobe, kprobe, ftrace, bpftrace, memory snooper reading /dev/mem, /dev/kmem, /proc/kcore will be detected and killed. Our wzshRUN 6.0 now provides 2 very usefull security enhancement programs. 1st one is the sysguard which will be run as daemon to prevennt above mentioned threats; 2nd one is the runcmd, this one will allow the users to run commands without need to worry that passwords entered to be stolen by softwarei ways.

2018-01-31: We have setup demo machine at AWS for public to test and win prize 3 times, each time last for almost a year. The condition to win the prize is very simple: anyone who can first find another software that has similar function to one of our software, but is more robust to against attacks and make the functions more reliable. However, no one has won the prize.

2017-07-17: Our Linux software can be used in Windows 10 Linux environment, so can make Windows 10 more secure.

2016-11-27: The password/passphrase read function used in our software now will kill the system call tracer process that attaches to our process; dtrace like process; processes that open system memory device or access our process' memory; process that opens our TTY. And it will continue to provide info for user to find possible TTY keylogger. On Linux platform, it will also try to prevent attacker to use Kprobe/Uprobe to steal the password/passphrase.

2016-11-13: Our recently updated WZSysGuard V5.1 provides an application security enhancement program: appguard. When supplied with those important applications' process IDs, the appguard process will detect whether those processes are being traced by system call tracer, debugger; dtrace like process created; processes that open system memory device or accessing those protected processes' memory. All these are possile hacking processes, so the appguard will try to kill them to minimize risk of secret info got stolen.

2016-11-13: Now, our updated wzshRUN V5.3 can help to enhance system's security: when a encrypted script is running, it can detect dtrace type of process, possible memory peeper, and kill them.
