“Recently, APT35 infiltrators have begun targeting government forces and armed forces to steal secret data.”

Fears of government and military networks have arisen all over the world in recent months due to a rise in targeted violations attributed to the Iranian alignment Threats Apt35.

The voltage, which was initially discovered in early 2025, uses harmful programs specifically designed to violate protected circumference and collect user passwords.

Early signs of hacking indicate emails speaking spears that contain HTML attachments that infiltrate the targeted environment when they are hidden by launching a multi -stage load.

According to the attack series analysis, Microsoft Office documents that benefit from Cve-2023-23397 are used to wander in the Outlook security structure repeatedly as an initial heading.

The main theft unit of credit data is recovered from the driving and control server (C2) far from the built -in code after downloading PowerShell Stager.

The researchers at Stromshield noted that the smooth shift from the exploitation of documents to the good poll and the accreditation nominated by researchers in the Ministry of Defense Network in April.

Once installed, harmful programs are offered as trusted system operations in order to avoid detection. In order to intercept NTLM exchanges for challenge, response and memory retail adoption data, it connects to a Windows security supply facade (SSPI).

Then this retail is sent to the attacker’s infrastructure, where the distinctive accounts are lock on valuable servers using a mixture of scrolling and retail methods.

Several accounts were hacked within military communications networks without stopping traditional infiltration systems, which had a great impact.

The dramatic symbol is like one recorded case like the following sample, which shows how the virus uses SSPI hooks from PowerShell: –

Infection mechanism

The download in two phases first determines the perimeter of the victim is the key to the infection mechanism.

After exploiting a successful document, the first Stager is achieved by the environment by wiping the loaded Kernel units and requesting the registration keys for safety tools.

To prevent reverse engineering attempts, implementation stops if a well -known sand box is found. If not, the Base64 car load is decoded from the second stage by Stager and written to % Appdata % Roaming Msnetcache.dll before downloading it using Rundl32.exe.

Viliam.ude-FINAL (.)

This DLL combines traffic with original HTTPS sessions through the SSPI logic application, intercepting accreditation data, then sending HTTP requests to C2 via 443 port.

All the things that have been taken into account, the campaign shows the increasing efficiency of APT35 in deep integration into reliable systems and the use of original application programming facades to obtain credit data without revealing clear artifacts.

To find such secret interventions before vital access, it is necessary to constant attention to advanced details and behavioral monitoring.
