OTX BotIranian Botnet Exposed via Open Directory: 15-Node Relay Network and Active C2
An Iranian threat actor's operational infrastructure was exposed through an open directory, revealing a 15-node relay network spanning Finland and Iran, an SSH-based botnet framework, and an active command and control server. The exposed bash history documented the full operation, including tunnel deployment, DDoS tooling development, and botnet creation. The actor used on-host compilation to evade detection and leveraged a Python script for mass SSH deployment. The botnet client, compiled and renamed 'hex' on infected hosts, showed automatic reconnection capabilities. This operation appears to be financially or personally motivated rather than state-directed, with infrastructure dual-purposed for censorship bypass and attack operations.

Two years later, the title was ported to the Amiga platform, and the following year to the Commodore 64, Amstrad CPC, Atari ST, MS-DOS, and ZX Spectrum. https://archivegame.org/action-fighter/ #game #sega #amiga #amstrad #atari #commodore64 #zxspectrum #dos
RondoDox Botnet: From Zero to 174 Exploited Vulnerabilities
The RondoDox botnet has emerged as a significant threat, exploiting 174 different vulnerabilities since May 2025. It primarily targets IoT devices and internet-exposed services for DoS attacks. The botnet's infrastructure includes exploiting and hosting components, with evidence suggesting the use of compromised residential IPs. RondoDox's operators have shown a rapid adoption of newly disclosed vulnerabilities, sometimes exploiting them within days of publication. The botnet's evolution includes a shift from a shotgun approach using numerous exploits to a more focused strategy targeting recent, critical vulnerabilities. The malware shares similarities with Mirai but focuses solely on DoS attacks. This threat highlights the importance of exposure management in cybersecurity.

Jarkko SakkinenMS-DOS indie gamedev, demoscene and similar "oldschool" forums usually recommend one of these options:
1. DJGPP
2. Turbo C++
3. Watcom C/C++
I possess MiSTeR FPGA with ao486 core so thought that would be a cool target to play a bit with but I need a development environment.
So... I created a development kit repository, providing tools to create MS-DOS COM an EXE files with the current GCC. It also provides ao486-simulation configs for dosbox-x and x86box. Finally it has a QEMU launcher emulating 486 SX 33 MHz, which matches ao486.
And yes, it's GCC + GAS thing plain and simple. I'm not really familiar with nasm etc. Before GAS it was TASM (Turbo Assembler) :-) Important thing here is that it has a C orchestrator and does not require FASM to provide MZ stub.
AKA edit-compiler-run delivered :-)
As a test run I have a test program does only some silly graphics but does give 486 a good test run given that:
1. 486 optimized codebase with a mentionable portion assembly (and I really did enjoy this).
2. Weird display mode in 320x240 256 color resolution and page flpping.
3. Configures memory to flat realmode (aka "unreal mode") and piggybacks lua-precalculated texture and palette to an additional .rodata_32 section.
Will be out in the foreseeable future...
