Amid renewed tensions concerning the U.S. and Russia more than Ukraine and Kazakhstan, American cybersecurity and intelligence companies on Tuesday produced a joint advisory on how to detect, respond to, and mitigate cyberattacks orchestrated by Russian point out-sponsored actors.
To that stop, the Cybersecurity and Infrastructure Security Company (CISA), Federal Bureau of Investigation (FBI), and Countrywide Security Company (NSA) have laid bare the tactics, procedures, and procedures (TTPs) adopted by the adversaries, including spear-phishing, brute-power, and exploiting known vulnerabilities to achieve preliminary obtain to focus on networks.
The checklist of flaws exploited by Russian hacking groups to get an initial foothold, which the agencies explained are “popular but effective,” are underneath —
- CVE-2018-13379 (FortiGate VPNs)
- CVE-2019-1653 (Cisco router)
- CVE-2019-2725 (Oracle WebLogic Server)
- CVE-2019-7609 (Kibana)
- CVE-2019-9670 (Zimbra computer software)
- CVE-2019-10149 (Exim Simple Mail Transfer Protocol)
- CVE-2019-11510 (Pulse Protected)
- CVE-2019-19781 (Citrix)
- CVE-2020-0688 (Microsoft Exchange)
- CVE-2020-4006 (VMWare)
- CVE-2020-5902 (F5 Massive-IP)
- CVE-2020-14882 (Oracle WebLogic)
- CVE-2021-26855 (Microsoft Trade, exploited usually along with CVE-2021-26857, CVE-2021-26858, and CVE-2021-27065)
“Russian state-sponsored APT actors have also shown innovative tradecraft and cyber capabilities by compromising third-party infrastructure, compromising 3rd-occasion software package, or acquiring and deploying custom malware,” the organizations stated.
“The actors have also shown the ability to preserve persistent, undetected, very long-time period entry in compromised environments — which includes cloud environments — by making use of respectable qualifications.”
Russian APT groups have been historically observed placing their sights on operational technology (OT) and industrial management techniques (ICS) with the purpose of deploying destructive malware, main between them remaining the intrusion strategies against Ukraine and the U.S. electrical power sector as properly as assaults exploiting trojanized SolarWinds Orion updates to breach the networks of U.S. government agencies.
To increase cyber resilience in opposition to this threat, the agencies advise mandating multi-issue authentication for all end users, hunting out for signals of irregular exercise implying lateral motion, enforcing network segmentation, and keeping functioning units, purposes, and firmware up to day.
“Take into account using a centralized patch management system,” the advisory reads. “For OT networks, use a risk-dependent evaluation strategy to determine the OT network belongings and zones that must take part in the patch administration method.”
Other mitigation tactics involve —
- Apply sturdy log collection and retention
- Involve accounts to have powerful passwords
- Permit solid spam filters to prevent phishing emails from achieving stop-buyers
- Carry out rigorous configuration management programs
- Disable all needless ports and protocols
- Be certain OT components is in go through-only manner
