Iranian Cyber Actors’ Brute Force and Credential Access Activity Compromises Critical Infrastructure Organizations
Cosa significa
CISA Cybersecurity Advisories ha pubblicato un advisory sul ransomware Iranian Cyber Actors’ Brute Force and Credential Access Activity Compromises Critical Infrastructure Organizations. Le misure indicate vanno confrontate con esposizione, identita, segmentazione e capacita di ripristino.
Perché conta
L'advisory descrive attivita ransomware osservate e misure difensive pubblicate da un'autorita. Non prova che il proprio perimetro sia compromesso, ma richiede una verifica prioritaria di esposizione e controlli.
Azioni consigliate
- Verificare e correggere con priorita i sistemi Internet-facing indicati dalla fonte; applicare MFA resistente al phishing, segmentazione e backup offline immutabili con prove di ripristino.
- Verificare sistemi esposti, accessi remoti e versioni rispetto all'advisory ufficiale.
- Confermare che backup offline e immutabili siano separati e ripristinabili.
- Correlare TTP e IOC pubblicati con la telemetria autorizzata del proprio perimetro.
Benefici operativi potenziali
- Prioritizzazione delle esposizioni Internet e delle vulnerabilita sfruttate
- Verifica dei controlli su accessi remoti, movimento laterale ed esfiltrazione
- Validazione documentata della capacita di ripristino
Traduzione in elaborazione
Il contenuto ufficiale è disponibile nella lingua originale. La versione italiana verrà pubblicata al termine dei controlli automatici.

Cybersecurity Advisory Iranian Cyber Actors’ Brute Force and Credential Access Activity Compromises Critical Infrastructure Organizations Release Date October 16, 2024 Alert Code AA24-290A Related topics: Cybersecurity Best Practices , Multifactor Authentication , Organizations and Cyber Safety Summary The Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), the Communications Security Establishment Canada (CSE), the Australian Federal Police (AFP), and Australian Signals Directorate's Australian Cyber Security Centre (ASD's ACSC) are releasing this joint Cybersecurity Advisory to warn network defenders of Iranian cyber actors’ use of brute force and other techniques to compromise organizations across multiple critical infrastructure sectors, including the healthcare and public health (HPH), government, information technology, engineering, and energy sectors. The actors likely aim to obtain credentials and information describing the victim’s network that can then be sold to enable access to cybercriminals. Since October 2023, Iranian actors have used brute force, such as password spraying, and multifactor authentication (MFA) ‘push bombing’ to compromise user accounts and obtain access to organizations. The actors frequently modified MFA registrations, enabling persistent access. The actors performed discovery on the compromised networks to obtain additional credentials and identify other information that could be used to gain additional points of access. The authoring agencies assess the Iranian actors sell this information on cybercriminal forums to actors who may use the information to conduct additional malicious activity. This advisory provides the actors’ tactics, techniques, and pr
