Iranian Cybergroup Toufan Targets Organizations to Steal Login Credentials

A pro-Palestinian cybergroup called Cyber Toufan, which means “cyber storm,” has become a serious threat to Israeli groups in the changing digital battlefield of the Israel-Gaza war.

Over the past year, this ideologically driven group has orchestrated over 100 breaches, focusing on sectors critical to Israel’s economy and security, including government, defense, finance, and infrastructure.

Escalating Cyber Warfare in the Israel-Gaza Conflict

Unlike traditional cybercriminals motivated by financial gain, Cyber Toufan’s operations are politically charged, aiming to disrupt, destabilize, and inflict reputational damage through meticulously timed data leaks on platforms like Telegram and dedicated leak sites.

Their attacks are not random but strategically targeted at entities with direct or indirect ties to Israeli interests, amplifying the psychological and political impact of their campaigns.

Cyber Toufan’s tactics reveal a sophisticated yet opportunistic approach, capitalizing on poor cybersecurity hygiene rather than relying on advanced malware or zero-day exploits.

According to the Report, Investigations by the OP Innovate Incident Response team into three confirmed intrusions highlight a consistent pattern: attackers gain initial access through weak or reused credentials lacking multi-factor authentication (MFA), often tied to externally managed VPN or firewall services provided by third-party vendors like Bezeq or Partner.

Exploiting Weak Security for Stealthy Intrusions

Once inside, they execute stealthy lateral movement using native tools like PowerShell and SMB/Windows Admin Shares, exploiting flat networks and unprotected file servers sometimes even guest accounts with no password to exfiltrate sensitive data.

Their methods map to the MITRE ATT&CK framework, covering reconnaissance (T1595), resource development (T1583), initial access via valid accounts (T1078), and defense evasion (T1027, T1562) by leveraging legitimate system tools to avoid detection.

This approach allows them to persist undetected until data is leaked, often weeks later, for maximum strategic effect.

The group’s operations also show evidence of parallel attacks, suggesting coordinated campaigns to amass large volumes of intelligence in a short timeframe, which are then selectively released to align with media cycles or geopolitical events.

The real challenge for targeted organizations lies in their own vulnerabilities missing centralized logging, insufficient retention (sometimes as short as a day), and lack of network segmentation have repeatedly enabled Cyber Toufan’s success.

Without comprehensive audit trails or real-time alerting, defenders struggle to trace attack paths or detect early reconnaissance, while flat internal networks allow attackers to pivot freely once inside.

To counter such threats, organizations must prioritize enforcing MFA across all remote access points, eliminating default or dormant accounts, segmenting networks with strict firewall rules, locking down file servers with least-privilege policies, and investing in robust logging solutions with extended retention periods of at least 90 days.

As Cyber Toufan continues to exploit basic misconfigurations, the message is clear: bolstering fundamental security practices is no longer optional but a critical line of defense against politically motivated cyber warfare.
