Multiple vulnerabilities have been discovered in Mozilla Firefox and Firefox Extended Support Release (ESR), the most severe of which could allow for remote code execution.
Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Multiple improper neutralization of special elements used in an OS command vulnerabilities (CWE-78) in the Web GUI of FortiWAN before 4.5.9 may allow an authenticated attacker to execute arbitrary commands on the underlying system’s shell via specifically crafted HTTP requests.
An improper input validation vulnerability in the sniffer interface of FortiSandbox before 3.2.2 may allow an authenticated attacker to silently halt the sniffer via specifically crafted requests.
FortiGuard Labs is aware of a new campaign from the APT10/Cicada threat actors. Reported by researchers at Symantec, this latest campaign highlights the various tools and custom malware used by Cicada to perform espionage activity, which we covered in our blog post from 2019, which used different TTPs. APT 10 is also referred to as:CicadaCVNXHOGFISH menuPassPOTASSIUM Stone Panda Red Apollo This group focuses specifically on the following verticals:GovernmentLegalPharmaceuticalReligiousTelecomNon-Governmental Organizations (NGOs)and targets multiple countries around the world, including in Europe, Asia, and North America. First seen attacking Japanese interests, Cicada has been observed targeting various managed service providers globally as well. Campaigns have been attributed to the government of China.As part of our membership with the Cyber Threat Alliance, all indicators of compromise (IOCs) were provided to us in advance before publication to ensure Fortinet protections were in place during the time of announcement.What are the Technical Details of Cicada?Cicada has been observed to use a custom loader and malware to perform their attacks. Various activities observed included attacks on Microsoft Exchange Servers. The report suggested that potential zero day exploits were likely used to gain access. Once inside, the attackers would deploy a loader and a custom backdoor known as Sodamaster.Sodamaster is fileless and evades sandbox detection, and enumerates various operating system parameters such as username, hostname, and OS of the targeted systems. It can also download and execute additional payloads. According to the report, the TTPs (Tactics, Techniques and Procedures) used by Cicada were in operation since 2020.Various tools used by Cicada are Mimikatz, rar archiving (file compression), system/network discovery (to determine what systems and services are running) , WMIExec (cmd line to execute commands remotely), and NBTscan (open source for network reconnaissance) tools. Other observations were the usage of VLCplayer that was exploited to act as a custom loader, and WinVnc for remote control of compromised machines.How Widespread is this?This is limited to targeted attacks.Who is Behind this Attack?This has been attributed to APT10 and is state sponsored. For further details on APT10, please refer to “Two Chinese Hackers Associated With the Ministry of State Security Charged with Global Computer Intrusion Campaigns Targeting Intellectual Property and Confidential Business Information” in the APPENDIX.What Operating Systems are Affected?Windows Operating Systems.What is the Status of Coverage?FortiGuard Labs has coverage in place for publicly available samples as:Riskware/MimikatzW64/HUILOADER.ZYJB!trW64/Ecipekac.M!trAll network IOCs are blocked by the WebFiltering client.
Multiple security issues have been found in the Mozilla Firefox web
browser, which could potentially result in the execution of arbitrary
code, information disclosure or spoofing.
FortiGuard Labs is aware of a report that a new Remote Access Trojan (RAT) called “Borat” is sold in underground forums. The RAT provides not only typical RAT capabilities such as keylogging, audio and webcam recording, and browser credential stealing to cybercriminals, but also offers file encryption and decryption capability as well as creating a ransom note on the victim’s machine.Why is this Significant?This is significant because Borat RAT not only enables cybercriminals to perform typical RAT activities but also provides ransomware capabilities as well.What Functionalities Does Borat RAT Provide?Borat RAT allows an attacker to perform the following activities:KeyloggingRansomware activities such as encrypting and decrypting files as well as creating a ransom note on the victim’s machineDistributed Denial of Service (DDoS)Audio and webcam recordingRemote desktopReverse proxySteals device infoProcess hollowingCredential stealingDiscord token stealingPlay audioSwap mouse buttonsHold mouseShow and hide the Desktop and the taskbarEnable and disable webcam lightHang systemTurn off the monitorDisplay blank screen What is the Status of Coverage?FortiGuard Labs provides the following AV coverage for Borat RAT:MSIL/Agent.CFQ!trMSIL/Keylogger.DUS!trMalicious_Behavior.SB
