The digital battleground surrounding the Israel-Gaza conflict has intensified dramatically over the past year, with politically motivated threat actors launching sophisticated campaigns against Israeli organizations and their international partners.
Among the most prominent of these groups is Cyber Toufan, an Iranian-linked hacktivist collective whose name translates to “cyber storm” in Arabic, signaling their ideological alignment with regional tensions and their destructive intentions.
Since late 2023, Cyber Toufan has claimed responsibility for over 100 successful breaches across multiple sectors, including government agencies, defense contractors, financial institutions, and critical infrastructure providers.

Unlike traditional cybercriminal organizations motivated by financial gain, this group operates with clear political objectives designed to disrupt, destabilize, and inflict reputational damage on entities connected to Israel’s economy and security apparatus.
OP Innovate analysts identified a concerning pattern in the group’s operations after investigating three confirmed Cyber Toufan intrusions over recent months.
The investigations revealed that these attacks follow a consistent methodology: initial access through weak or reused credentials without multi-factor authentication, followed by stealthy lateral movement across compromised networks, and culminating in coordinated data leak campaigns distributed publicly via Telegram channels.

What sets Cyber Toufan apart from more technically advanced persistent threat groups is their deliberate exploitation of basic security negligence rather than sophisticated zero-day vulnerabilities.
The group has demonstrated remarkable success by targeting organizations whose VPN or firewall infrastructure is managed by third-party service providers, particularly those using services from companies like Bezeq and Partner.
In these scenarios, attackers exploit default or previously leaked credentials associated with service provider configurations, essentially walking through unlocked digital doors rather than breaking them down.

The group’s tactical approach reveals a preference for “living off the land” techniques, utilizing legitimate administrative tools such as PowerShell and PsExec to navigate compromised networks without deploying custom malware.
This methodology allows them to blend seamlessly with normal system activity while avoiding detection by traditional antivirus solutions.
Attack Methodology and Technical Analysis
Cyber Toufan’s operational framework demonstrates sophisticated planning despite relying on basic attack vectors.
Their reconnaissance phase involves comprehensive mapping of external attack surfaces, specifically targeting organizations with exposed servers, firewall interfaces, and VPN administrative panels.
The group actively hunts for leaked or stolen credentials from infostealer logs, previous breaches, and credential marketplaces, prioritizing low-friction access routes that bypass security controls.
Once inside target networks, the attackers conduct systematic internal scanning to locate machines with exposed and unprotected SMB shares, often encountering configurations with no password enforcement or weak credential protection.
This lateral movement strategy leverages native Windows file-sharing protocols and administrative shares, enabling data collection without triggering security alerts or requiring endpoint compromise.
The exfiltration phase operates with strategic timing, as stolen data is often extracted via SMB or remote administrative tools, staged in compressed archives, and transferred over encrypted channels.
Critically, the group coordinates large-scale exfiltration across multiple victims simultaneously, suggesting intentional intelligence collection efforts before exposure, with data leaks deliberately delayed for maximum psychological and strategic impact.
