Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts. Without knowledge of the password for an account, an adversary may opt to systematically guess the password using a repetitive or iterative mechanism. An adversary may guess login credentials without prior knowledge of system or environment passwords during an operation by using a list of common passwords. Password guessing may or may not take into account the target's policies on password complexity or use policies that may lock accounts out after a number of failed attempts. Guessing passwords can be a risky option because it could cause numerous authentication failures and account lockouts, depending on the organization's login failure policies. (Citation: Cylance Cleaver) Typically, management services over commonly used ports are used when guessing passwords. Commonly targeted services include the following: * SSH (22/TCP) * Telnet (23/TCP) * FTP (21/TCP) * NetBIOS / SMB / Samba (139/TCP & 445/TCP) * LDAP (389/TCP) * Kerberos (88/TCP) * RDP / Terminal Services (3389/TCP) * HTTP/HTTP Management Services (80/TCP & 443/TCP) * MSSQL (1433/TCP) * Oracle (1521/TCP) * MySQL (3306/TCP) * VNC (5900/TCP) * SNMP (161/UDP and 162/TCP/UDP) In addition to management services, adversaries may "target single sign-on (SSO) and cloud-based applications utilizing federated authentication protocols," as well as externally facing email applications, such as Office 365.(Citation: US-CERT TA18-068A 2018). Further, adversaries may abuse network device interfaces (such as `wlanAPI`) to brute force accessible wifi-router(s) via wireless authentication protocols.(Citation: Trend Micro Emotet 2020) In default environments, LDAP and Kerberos connection attempts are less likely to trigger events over SMB, which creates Windows "logon failure" event ID 4625.

Примеры процедур
Название Описание
China Chopper

China Chopper's server component can perform brute force password guessing against authentication portals.(Citation: FireEye Periscope March 2018)
Emotet

Emotet has been observed using a hard coded list of passwords to brute force user accounts. (Citation: Malwarebytes Emotet Dec 2017)(Citation: Symantec Emotet Jul 2018)(Citation: US-CERT Emotet Jul 2018)(Citation: Secureworks Emotet Nov 2018)(Citation: CIS Emotet Dec 2018)

SpeakUp

SpeakUp can perform brute forcing using a pre-defined list of usernames and passwords in an attempt to log in to administrative panels. (Citation: CheckPoint SpeakUp Feb 2019)
APT28

APT28 has used a brute-force/password-spray tooling that operated in two modes: in brute-force mode it typically sent over 300 authentication attempts per hour per targeted account over the course of several hours or days.(Citation: Microsoft STRONTIUM New Patterns Cred Harvesting Sept 2020) APT28 has also used a Kubernetes cluster to conduct distributed, large-scale password guessing attacks.(Citation: Cybersecurity Advisory GRU Brute Force Campaign July 2021)
CrackMapExec

CrackMapExec can brute force passwords for a specified user on a single target system or across an entire network.(Citation: CME Github September 2018)
HermeticWizard

HermeticWizard can use a list of hardcoded credentials in attempt to authenticate to SMB shares.(Citation: ESET Hermetic Wizard March 2022)
Lucifer

Lucifer has attempted to brute force TCP ports 135 (RPC) and 1433 (MSSQL) with the default username or list of usernames and passwords.(Citation: Unit 42 Lucifer June 2020)
Pony

Pony has used a small dictionary of common passwords against a collected list of local accounts.(Citation: Malwarebytes Pony April 2016)

Xbash

Xbash can obtain a list of weak passwords from the C2 server to use for brute forcing as well as attempt to brute force services with open ports.(Citation: Unit42 Xbash Sept 2018)(Citation: Trend Micro Xbash Sept 2018)
P.A.S. Webshell

P.A.S. Webshell can use predefined users and passwords to execute brute force attacks against SSH, FTP, POP3, MySQL, MSSQL, and PostgreSQL services.(Citation: ANSSI Sandworm January 2021)

Update Software

Perform regular software updates to mitigate exploitation risk.
Multi-factor Authentication

Use two or more pieces of evidence to authenticate to a system; such as username and password in addition to a token from a physical smart card or token generator.
Password Policies

Set and enforce secure password policies for accounts.
Account Use Policies

Configure features related to account use like login attempt lockouts, specific login times, etc.

Обнаружение

Monitor authentication logs for system and application login failures of Valid Accounts. If authentication failures are high, then there may be a brute force attempt to gain access to a system using legitimate credentials.
