■■■■□ SectorA01 (Lazarus) employed a highly sophisticated, multi-stage attack chain
beginning with social engineering via a fake official Deriv trading platform installer (NSIS-based).
The infection progresses through a polyglot payload sequence (NSIS → Electron/JavaScript → Python → .NET), using dynamic code execution via eval() on remotely fetched JavaScript, Pastebin as a dead-drop mechanism with 1,000 pre-generated XOR-encrypted URLs, and Living-off-the-Land techniques by downloading and installing the legitimate official Python interpreter when absent.

Once inside, the malware conducts broad data theft including browser credentials and credit-card information, keylogging with clipboard monitoring and exfiltration, and keyword-based recursive searches for sensitive files (wallet, mnemonic, .env, etc.).
It establishes strong remote access through an AnyDesk backdoor using a pre-configured fixed password via service.conf overwrite, while achieving multi-layered persistence through the startup folder, scheduled tasks, and AnyDesk auto-start.

Defense evasion is comprehensive: it disables Windows Defender and Firewall while adding exclusions, masquerades as the legitimate system process Runtime Broker.exe, tampers PE timestamps to future dates (2070 and 2093), communicates in the final stage exclusively over Tor via a .onion C2 domain, and incorporates automatic client updates with trace self-deletion to hinder detection and analysis.

■■□□□ The Central Bank of India (RBI) 🇮🇳 has made a good decision from cyber security perspective.

They have forced all bank websites to be subdomains of bank.in

This will effectively cause most phishing campaigns to go astray.

■□□□ 💥 Cyber-War on Israel: Transport display outages; new details on cyber intrusion into "Urban Digital" company.

🎤Following a widespread disruption in transport information displays in the occupied territories, Hebrew sources confirmed that the incident originated from a cyber intrusion into the infrastructure of the "Urban Digital" company. This attack disabled parts of the smart displays in cities such as Ashkelon and Modiin for about an hour.

🎥The management of the company owning "Urban Digital" announced that to contain the incident, all servers were completely shut down and more than 100 experts were active until morning to control the situation.

🎤Initial assessment indicates that the attackers are from the same groups that have targeted several other organizations of this regime in recent months. Technical investigation is ongoing.

■■■■□ Hackers posing as Kyrgyzstan’s Justice Ministry are spreading 2013-era NetSupport RAT across Kyrgyzstan and Uzbekistan using fake PDFs and old Java tricks—blocking outsiders to hide the attack.
■□□□□ CVE-2025-5318
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
