Foreign adversaries typically spend years attempting to penetrate government systems such as these, using stealth to avoid being seen and carefully hiding any tells or tracks. First, unauthorized access must be revoked and proper authentication protocols restored. To address these vulnerabilities, three immediate steps are essential.
The attackers exploited a vulnerability in software from Kaseya , a Miami-based company whose products help systemadministrators manage large networks remotely. As its name suggests, CVE-2015-2862 was issued in July 2015. It’s from 2015!” “It’s a patch for their own software.
The vulnerability could potentially allow an authenticated attacker to gain access to corporate network, access to sensitive data, and control private clouds within an entire infrastructure. “An authenticated actor may be able to send malicious traffic to VMware Cloud Director which may lead to arbitrary remote code execution.
A baseboard management controller (BMC) is a specialized service processor that monitors the physical state of a computer, network server or other hardware device using sensors and communicating with the systemadministrator through an independent connection. ” continues the analysis. Pierluigi Paganini.
Systemadministrators need to employ security best practices with the systems they manage.” Str ong passw ords, a vulnerability remediation plan, and two factors of authentication can go a long way to keep systems secure from the most basic and common attacks.” ” Cashdollar concludes.
In many cases, the web interface can be accessed without authentication. “They all come with a default username and “1234” as the default password, which is rarely changed by systemadministrators.” Copyright (C) 2014-2015 Media.net Advertising FZ-LLC All Rights Reserved -->. Pierluigi Paganini.
Webmin is an open-source web-based interface for systemadministration for Linux and Unix. To exploit the malicious code, your Webmin installation must have Webmin -> Webmin Configuration -> Authentication -> Password expiry policy set to Prompt users with expired passwords to enter a new one. Pierluigi Paganini.
In this type of distributed denial of service (DDoS) attack, the malicious traffic generated with the technique is greater than the once associated with the use of memcached, a service that does not require authentication but has been exposed on the internet by inexperienced systemadministrators. Brasília time, 1:00 p.m.
The Center for Internet Security (CIS) has a reference that can help systemadministrators and security teams establish a benchmark to secure their Docker engine. Ensure that container images are authenticated, signed, and from a trusted registry (i.e., Docker Trusted Registry ). Pierluigi Paganini.
The vulnerability could be exploited by an authenticated, local attacker to execute arbitrary commands as a privileged user. ” Cisco advisory reveals that the vulnerability could be exploited remotely by leveraging the operating system remote management tools. when running on a Microsoft Windows end-user system. “The
Audit user accounts with administrative privileges and configure access controls with least privilege in mind, and use multifactor authentication. CVE-2015-1635 : An RCE vulnerability in specific versions of Windows (e.g., CVE-2015-1635 : An RCE vulnerability in specific versions of Windows (e.g., 7 SP1, 8, 8.1)
A code signing certificate is used to authenticate the identity of a software developer or publisher, and it provides cryptographic assurance that a signed piece of software has not been altered or tampered with. The two leaked Nvidia certificates have expired, being valid from 2011 to 2014 and 2015 to 2018.
The CVE-2018-15442 vulnerability could be exploited by an authenticated, local attacker to execute arbitrary commands as a privileged user. Cisco advisory reveals that the vulnerability could be also exploited remotely by leveraging the operating system remote management tools. when running on a Microsoft Windows end-user system.
The threat actors leverage perfectly orchestrated social engineering technique by “persuading” people holding significant corporate positions to open a non-malicious PDF email attachment coming from an authentic address in their contacts. The page resembles an authentic Microsoft Office 365 file sharing page. Pierluigi Paganini.
We were able to trace the implant back to at least 2015, along with variants intended to hijack the execution of Telegram and Chrome applications as a persistence method. Ferocious Kitten is one of the groups that operate in a wider eco-system intended to track individuals in Iran. Notify your supervisors as soon as possible.
The CISA agency provides recommendations for systemadministrators and owners to enhance the level of security of their organizations: Maintain up-to-date antivirus signatures and engines. Keep operating system patches up-to-date. If these services are required, use strong passwords or Active Directory authentication.
“In July 2017, Equifax systemadministrators discovered that attackers had gained. Digital certificates are encrypted electronic tokens that are used to authenticate servers and systems. Because this one was expired, the system was unable to inspect encrypted traffic. The network. Pierluigi Paganini.
