RipperSec Downs Nature Israel in #OpZionistV2 DDoS Attack

Israel’s oldest and largest independent environmental nonprofit has become the latest target in an ongoing wave of politically motivated cyberattacks against Israeli-affiliated organizations. Nature Israel, which supports the Society for the Protection of Nature in Israel (SPNI), suffered prolonged downtime after its website, natureisrael.org, was targeted in the #OpZionistV2 campaign led by the hacktivist group RipperSec alongside its ally, The Comrade’s Group.

Target and Operation Background

Through its official Telegram channel, RipperSec announced a new target on August 7, 2026, at 15:00 local time (GMT+8) under the #OpZionistV2 banner. The announced target was Nature Israel, the organization supporting SPNI, Israel’s oldest and largest independent nature conservation body.The announcement included a warning message directed at parties the group associates with Israeli government policy: “Stop Killings People, We Are Watching Your Action.”

Technical Attack Details

Screenshots of the attack panels circulated on RipperSec’s Telegram channel show that the operation was carried out using several stresser tools in rotation across multiple rounds. One panel, Zeus Stresser, shows an attack configured with the TLS – HTTP/2 Flooder high rps (No CF) method, a 120-second duration, eight concurrent threads out of a maximum of 30, a rate limit of 32, and traffic geolocation set to World Wide. The panel confirmed “The attack was sent successfully” against https://natureisrael.org on port 443.

A subsequent wave relied on the MegaMedusa engine, whose execution logs show repeated requests against the target’s IP address, recording a mix of Request timed out, No Title Detected (504), 502 Bad Gateway, and connect ECONNREFUSED errors on 34.74.129.120:443. A third tool, Cybernetic Wolf, was also deployed with a configuration of 1,000 attack threads and a 100ms rate limit per worker, indicating the operation was sustained across multiple waves rather than a single strike.

Impact and Site Status

Third-party verification reports from check-host.net and check-host.cc, shared by RipperSec, show natureisrael.org unreachable from dozens of monitoring nodes worldwide , including Tirana, Sydney, Novi Travnik, Sofia, and São Paulo , all returning uniform NETWORK ERROR [ECONNREFUSED] errors. Direct attempts to load the site during this window returned 504 Gateway Time-out pages, “This page isn’t working” messages, and “This site can’t be reached” errors with the code ERR_CONNECTION_ABORTED.Following the attack waves, RipperSec published a “TARGET DOWN” status update alongside check-host report links as supporting evidence. Activity continued through at least four additional attack rounds, indicating a sustained effort to keep the site offline over an extended period.

About RipperSec and #OpZionistV2

RipperSec is a hacktivist group known for launching DDoS attacks against websites it considers affiliated with Israel amid the ongoing escalation in the Middle East. The #OpZionistV2 campaign continues a pattern from earlier operations: announcing targets via Telegram, executing attacks with a mix of commercial and open-source stresser tools, and publishing downtime evidence through third-party monitoring services as proof for followers.

In this incident, RipperSec also credited a group called The Comrade’s Group as an operational partner, reflecting a broader pattern of cross-group collaboration increasingly seen in geopolitically motivated hacktivist campaigns in the region.

CyberAsia.io will continue monitoring developments in the #OpZionistV2 campaign and will update this article as further information on impact or response from the affected party becomes available.

Verification Status

RipperSec posted Zeus Stresser, MegaMedusa, and Cybernetic Wolf panel screenshots plus check-host links. Those artifacts support a claimed Layer 7 / TLS flood against natureisrael.org on port 443, including a 34.74.129.120:443 address in their logs. CyberAsia did not operate a probe of our own. Treat the outage as a claimed disruption corroborated by third-party checkers they selected, not as a confirmed application compromise or data theft. No dump, no admin panel, no credential leak was attached to this wave.

TTP Notes: MegaMedusa and HTTP/2 Flooders

The TLS HTTP/2 flooder setting marked “No CF” is an operator hint that they believed the host was not behind Cloudflare. HTTP/2 multiplexing lets a small volunteer panel generate high request-per-second load without a classic volumetric botnet. MegaMedusa logs mixing 504, 502, and ECONNREFUSED usually mean the origin or load balancer gave up, not that the CMS was popped. Nonprofits on cheap VPS plus a single A record are the typical casualty class for this campaign style.

Mitigation & Prevention Strategies

For the affected organization / IT team.

• Put a real DDoS edge in front of origin. HTTP/2 and TLS flood controls, bot challenges, and hide the origin IP that appeared in MegaMedusa logs.
• Do not leave admin or staging on the same IP. Split WordPress login and donor portals onto a separate host so a public homepage flood does not take payments down.
• Rate-limit and cache anonymous GET/HEAD. Most of this campaign is unauthenticated HTTPS requests, not logged-in abuse.

For staff and supporters.

• If the site is down, use the organization’s social accounts for updates. Do not click “mirror” or donation links that appear in random Telegram comments during an outage.
• Ignore any message that claims to be a ransom or a leak tied to this DDoS. This wave, as published, was a takedown claim only.
