FBI, NSA and CISA Warns of Russian Hackers Targeting Critical Infrastructure

FBI, NSA and CISA Warns of Russian Hackers Targeting Critical Infrastructure

January 12, 2022Ravie Lakshmanan
Amid renewed tensions between the U.S. and Russia over  Ukraine  and  Kazakhstan , American cybersecurity and intelligence agencies on Tuesday released a joint advisory on how to detect, respond to, and mitigate cyberattacks orchestrated by Russian state-sponsored actors. To that end, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), and National Security Agency (NSA) have laid bare the tactics, techniques, and procedures (TTPs) adopted by the adversaries, including spear-phishing, brute-force, and  exploiting known vulnerabilities  to gain initial access to target networks. The list of flaws exploited by Russian hacking groups to gain an initial foothold, which the agencies said are "common but effective," are below — CVE-2018-13379  (FortiGate VPNs) CVE-2019-1653  (Cisco router) CVE-2019-2725  (Oracle WebLogic Server) CVE-2019-7609  (Kibana) CVE-2019-9670  (Zimbra software) CVE-2019-10149  (Exim Simple Mail Transf
CISA, FBI and NSA Publish Joint Advisory and Scanner for Log4j Vulnerabilities

CISA, FBI and NSA Publish Joint Advisory and Scanner for Log4j Vulnerabilities

December 23, 2021Ravie Lakshmanan
Cybersecurity agencies from Australia, Canada, New Zealand, the U.K., and the U.S. on Wednesday released a joint advisory in response to widespread exploitation of multiple vulnerabilities in Apache's Log4j software library by nefarious adversaries. "These vulnerabilities, especially Log4Shell, are severe," the intelligence agencies said in the  new   guidance . "Sophisticated cyber threat actors are actively scanning networks to potentially exploit  Log4Shell ,  CVE-2021-45046 , and  CVE-2021-45105  in vulnerable systems. These vulnerabilities are likely to be exploited over an extended period." An attacker can exploit Log4Shell (CVE-2021-44228) by submitting a specially crafted request to a vulnerable system that causes that system to execute arbitrary code. CVE-2021-45046, on the other hand, allows for remote code execution in certain non-default configurations, while CVE-2021-45105 could be leveraged by a remote attacker to cause a denial-of-service (DoS
CISA Compliance for 2022

CISA Compliance for 2022

December 20, 2021The Hacker News
The last several years have seen an ever-increasing number of cyber-attacks, and while the frequency of such attacks has increased, so too has the resulting damage. One needs only to look at  CISA's list of significant cyber incidents  to appreciate the magnitude of the problem. In May of 2021, for example, a ransomware attack brought down the Colonial Pipeline, causing a serious fuel disruption for much of the United States. Just last month, a hacking group gained access to call logs and text messages from telecommunications carriers all over the world. These are just two of dozens of cyber-attacks occurring this year. Because of these and other cyber security incidents, the Department of Homeland Security issues a  compulsory directive  to federal agencies to better protect federal information systems and the data that they contain against cyber-attack. This directive is based around  CISA's catalog of vulnerabilities  that are known to pose a significant risk. The directi

Why Everyone Needs to Take the Latest CISA Directive Seriously

December 03, 2021The Hacker News
Government agencies publish notices and directives all the time. Usually, these are only relevant to government departments, which means that nobody else really pays attention. It's easy to see why you would assume that a directive from CISA just doesn't relate to your organization. But, in the instance of the latest CISA directive, that would be making a mistake. In this article, we explain why, even if you're in the private or non-government sector, you should nonetheless take a close look at CISA Binding Operational Directive 22-01. We outline why CISA was forced to issue this directive, and why that firm action has implications for all organizations – inside and outside of government. Acting on cybersecurity issues isn't as simple as flicking a switch, of course, so keep reading to find out how you can address the core issue behind the CISA directive. Okay, so what exactly is a CISA directive? Let's take a step back to gain some context. Just like any organ
CISA Warns of Actively Exploited Critical Zoho ManageEngine ServiceDesk Vulnerability

CISA Warns of Actively Exploited Critical Zoho ManageEngine ServiceDesk Vulnerability

December 02, 2021Ravie Lakshmanan
The U.S. Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) are warning of active exploitation of a newly patched flaw in Zoho's ManageEngine ServiceDesk Plus product to deploy web shells and carry out an array of malicious activities. Tracked as  CVE-2021-44077  (CVSS score: 9.8), the issue relates to an unauthenticated, remote code execution vulnerability affecting ServiceDesk Plus versions up to and including 11305 that, if left unfixed, "allows an attacker to upload executable files and place web shells that enable post-exploitation activities, such as compromising administrator credentials, conducting lateral movement, and exfiltrating registry hives and Active Directory files," CISA  said . "A security misconfiguration in ServiceDesk Plus led to the vulnerability," Zoho  noted  in an independent advisory published on November 22. "This vulnerability can allow an adversary to execute arbitrary code
CISA Issues Warning On Cyber Threats Targeting Water and Wastewater Systems

CISA Issues Warning On Cyber Threats Targeting Water and Wastewater Systems

October 15, 2021Ravie Lakshmanan
The U.S. Cybersecurity Infrastructure and Security Agency (CISA) on Thursday warned of continued ransomware attacks aimed at disrupting water and wastewater facilities (WWS), highlighting five incidents that occurred between March 2019 and August 2021. "This activity—which includes attempts to compromise system integrity via unauthorized access—threatens the ability of WWS facilities to provide clean, potable water to, and effectively manage the wastewater of, their communities," CISA, along with the Federal Bureau of Investigation (FBI), the Environmental Protection Agency (EPA), and the National Security Agency (NSA),  said  in a joint bulletin. Citing spear-phishing, outdated operating systems and software, and control system devices running vulnerable firmware versions as the primary intrusion vectors, the agencies singled out five different cyber attacks from 2019 to early 2021 targeting the WWS Sector — A former employee at Kansas-based WWS facility unsuccessfully
CISA Warns of Actively Exploited Zoho ManageEngine ADSelfService Vulnerability

CISA Warns of Actively Exploited Zoho ManageEngine ADSelfService Vulnerability

September 08, 2021Ravie Lakshmanan
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday issued a bulletin warning of a zero-day flaw affecting Zoho ManageEngine ADSelfService Plus deployments that is currently being actively exploited in the wild. The flaw, tracked as  CVE-2021-40539 , concerns a REST API authentication bypass that could lead to arbitrary remote code execution (RCE). ADSelfService Plus builds up to 6113 are impacted. ManageEngine ADSelfService Plus is an integrated self-service password management and a single sign-on solution for Active Directory and cloud apps, enabling admins to enforce two-factor authentication for application logins and users to reset their passwords. "CVE-2021-40539 has been detected in exploits in the wild. A remote attacker could exploit this vulnerability to take control of an affected system," CISA  said , urging companies to apply the latest security update to their ManageEngine servers and "ensure ADSelfService Plus is not directl
