These activities could be associated with the Islamic Revolutionary Guard Corps (IRGC) and could be used for propaganda purposes. This situation can be seen as an opportunity for the mitigation of defense strategies and vulnerabilities. It is important to continually take security measures against threats to IT and OT systems and to prevent attacks by reducing known risks.<span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">At this point, the support of cybersecurity companies like SOCRadar is of great importance. SOCRadar can assist companies in the proactive detection and mitigation of cyber threats. Services offered by SOCRadar include threat intelligence, digital risk management, brand protection,. These services enable companies to build a more effective defense against cyber threats. In particular, SOCRadar’s<a href="https://socradar.io/suites/cyber-threat-intelligence/"><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(17, 85, 204); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; text-decoration-line: underline; vertical-align: baseline;"> threat intelligence</a><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;"> and <a href="https://socradar.io/suites/brand-protection/"><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(17, 85, 204); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; text-decoration-line: underline; vertical-align: baseline;">digital risk management services </a><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">can help companies detect cyber threats earlier and take measures against these threats..

<h3 style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;">Brute Force</h3><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">Adversaries may use brute force techniques to gain access to accounts.. Without knowledge of the password for an account or set of accounts, an adversary may systematically guess the password using a repetitive or iterative mechanism. Brute forcing passwords can take place via interaction with a service that will check the validity of those credentials or offline against previously acquired credential data, such as password hashes. <span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">Brute forcing credentials may take place at various points during a breach. For example, adversaries may attempt to brute force access to Valid Accounts within a victim environment leveraging knowledge gathered from other post-compromise behaviors such as OS Credential Dumping, Account Discovery, or Password Policy Discovery. Adversaries may also combine brute forcing activity with behaviors such as External Remote Services as part of Initial Access.<span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(0, 0, 0);

These mitigations align with the Cross-Sector Cybersecurity Performance Goals (CPGs) developed by CISA and the National Institute of Standards and Technology (NIST). The CPGs provide a minimum set of practices and protections that CISA and NIST recommend all organizations implement.
