Threat analysis; your attack surface.

• Source: QNAP warns of critical auth bypass flaw in its NAS devices. The Taiwanese Network Attached Storage (NAS) device maker disclosed three vulnerabilities that can lead to an authentication bypass, command injection, and SQL injection.
  

  • CVE-2024-21899: If exploited, the improper authentication vulnerability could allow users to compromise the security of the system via a network.
    
  • CVE-2024-21900: If exploited, the injection vulnerability could allow authenticated users to execute commands via a network.
    
  • CVE-2024-21901: If exploited, the SQL injection vulnerability could allow authenticated administrators to inject malicious code via a network.
    

• The flaws impact various versions of QNAP's operating systems, including QTS 5.1.x, QTS 4.5.x, QuTS hero h5.1.x, QuTS hero h4.5.x, QuTScloud c5.x, and the myQNAPcloud 1.0.x service.
  

• Source: Switzerland: Play ransomware leaked 65,000 government documents. In a new statement published today, the Swiss government confirmed that 65,000 government documents were leaked in the breach.

Relevance of the published data volume.

The data package published on the darknet comprised around 1.3 million files. Once the data had been downloaded, the NCSC took the lead in systematically categorising and triaging all documents relevant to the Federal Administration. The results showed that the volume of data relevant to the Federal Administration comprised around 65,000 documents, or approximately 5% of the total published data set. The majority of these files belonged to Xplain (47,413) with a share of over 70%; around 14% (9,040) belonged to the Federal Administration. Around 95% of the Federal Administration’s files belonged to the administrative units of the Federal Department of Justice and Police (FDJP): the Federal Office of Justice, Federal Office of Police, State Secretariat for Migration and the internal IT service centre ISC-FDJP. With just over 3% of the data, the Federal Department of Defence, Civil Protection and Sport (DDPS) is slightly affected and the other departments are only marginally affected in terms of volume.

Proportion of sensitive data.

Sensitive content such as personal data, technical information, classified information and passwords was found in around half of the Federal Administration's files (5,182). Personal data such as names, email addresses, telephone numbers and postal addresses were found in 4,779 of these files. In addition, 278 files contained technical information such as documentation on IT systems, software requirement documents or architectural descriptions, 121 objects were classified in accordance with the Information Protection Ordinance and 4 objects contained readable passwords.

• Supporting Source: Information about the hacker attack on Xplain.
  

Xplain filed a criminal complaint after the incident, provided the authorities with all the necessary information and cooperated with them in investigating and limiting the damage. We rebuilt the entire IT infrastructure in accordance with the recommendations of the National Cyber Security Center (NCSC) and replaced the external operators. An external audit of the infrastructure and processes was completed in November. The NCSC subsequently wrote an assessment of the audit. The Federal Council's strategy crisis team on data leaks (PSC-D) took note of the report.

• Spoofed Zoom, Google & Skype Meetings Spread Corporate RATs.
  

A threat actor is creating fake Skype, Google Meet, and Zoom meetings, mimicking these popular collaboration applications to spread various commodity malware that can steal sensitive data from both Android and Windows users.

• Additional Information.
  • What is a "Data Breach"? A data breach is a security violation, in which sensitive, protected or confidential data is copied, transmitted, viewed, stolen, altered or used by an individual unauthorized to do so.
  • What is "Malware"? Malware (a portmanteau for malicious software) is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy.
  • What is a "Payload"? In the context of a computer virus or worm, the payload is the portion of the malware which performs malicious action; deleting data, sending spam or encrypting data. In addition to the payload, such malware also typically has overhead code aimed at simply spreading itself, or avoiding detection.
  • What is "Phishing"? Phishing is a form of social engineering where attackers deceive people into revealing sensitive information or installing malware such as ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim is navigating the site, and transverse any additional security boundaries with the victim.
  • Social engineering (security) In the context of information security, social engineering is the psychological manipulation of people into performing actions or divulging confidential information. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in that it is often one of many steps in a more complex fraud scheme.
    
  • What is "Information Security" (InfoSec)? Information security, sometimes shortened to InfoSec, is the practice of protecting information by mitigating information risks. It is part of information risk management.
    • Information Security Attributes: Confidentiality, Integrity and Availability (C.I.A.). Information Systems are composed in three main portions, hardware, software and communications with the purpose to help identify and apply information security industry standards, as mechanisms of protection and prevention, at three levels or layers: physical, personal and organizational. Essentially, procedures or policies are implemented to tell administrators, users and operators how to use products to ensure information security within the organizations.
  • What is "Risk management"? Risk management is the identification, evaluation, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities.
  • What is a "Vulnerability" (computing)? Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system. Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware.
  • What is an "Attack Surface"? The attack surface of a software environment is the sum of the different points (for "attack vectors") where an unauthorized user (the "attacker") can try to enter data to or extract data from an environment. Keeping the attack surface as small as possible is a basic security measure.
  • What is an "Attack Vector"? In computer security, an attack vector is a specific path, method, or scenario that can be exploited to break into an IT system, thus compromising its security. The term was derived from the corresponding notion of vector in biology. An attack vector may be exploited manually, automatically, or through a combination of manual and automatic activity.
  • What is "Standardization"? Standardization is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, or quality. It can also facilitate a normalization of formerly custom processes.
    • List of computer standards.
    • List of technical standard organizations.
  • What is a "Replay attack"? A replay attack is a form of network attack in which valid data transmission is maliciously or fraudulently repeated or delayed. Another way of describing such an attack is: "an attack on a security protocol using a replay of messages from a different context into the intended (or original and expected) context, thereby fooling the honest participant(s) into thinking they have successfully completed the protocol run."
  • What is a "Man-in-the-middle attack"? In cryptography and computer security, a man-in-the-middle, ..., attack is a cyberattack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other, as the attacker has inserted themselves between the two parties.
  • What is "Transport Layer Security" (TLS)? Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
  • What is a "Handshake" (computing)?. In computing, a handshake is a signal between two devices or programs, used to, e.g., authenticate, coordinate. An example is the handshaking between a hypervisor and an application in a guest virtual machine.
  • What is Security theater? The practice of taking security measures that are considered to provide the feeling of improved security while doing little or nothing to achieve it.
