3cx and supply chain attacks
Overview of the 3CX supply chain attack
3CX, a popular provider of softphone services to large corporations, has disclosed a supply chain attack that affected its desktop phone app, 3CXDesktopApp. The attack, which is suspected to have been ongoing since March 3, 2023, may have compromised the communications of up to 12 million daily users. Malicious DLLs were loaded into the Windows and Mac versions of the app, creating a backdoor on affected systems. The attack was discovered after users reported the app's suspicious behaviour on March 22, and on March 29th, multiple vendors confirmed the malware issue. 3CX advises customers to use the web-based app instead of the desktop application until a fix is provided. This supply chain attack, which may have been an advanced persistent threat, highlights the need for companies to maintain strict security protocols and be vigilant about potential vulnerabilities in their software supply chain.

What are supply chain attacks?
In recent years, supply chain attacks have become an increasingly prevalent and concerning issue for businesses and individualA supply chain attack is a type of cyber attack that targets a company's or organization's supply chain, which is the network of businesses and individuals that contribute to the creation and delivery of a product or service. These attacks can have devastating consequences, including data breaches, theft of sensitive information, and malware infections.
One particularly dangerous type of supply chain attack is a software supply chain attack. In this type of attack, hackers target the software that a company uses, such as a popular operating system or application, and inject malware or other malicious code into it. When users download and install the compromised software, the malware is also installed, giving the hackers access to sensitive data and control over the affected systems.
One of the most infamous examples of a software supply chain attack occurred in 2017, when hackers used a compromised version of the popular Ukrainian accounting software MeDoc to distribute the NotPetya malware. This attack caused widespread disruption and financial losses for numerous companies around the world.
Another recent example of a software supply chain attack was the SolarWinds attack in late 2020, in which hackers compromised the software update process for SolarWinds' Orion software, allowing them to infiltrate numerous organizations, including multiple US government agencies.
Software supply chain attacks can be particularly difficult to detect and prevent, as they often involve compromising trusted software vendors or providers. However, there are some steps that businesses and individuals can take to reduce their risk of falling victim to a supply chain attack:
Stay up-to-date with software patches and updates. Companies should ensure that they regularly install updates and patches for all software and systems, as these often include security fixes that can help prevent attacks.
Use trusted software vendors and providers. Businesses should carefully vet all software vendors and providers to ensure that they have robust security measures in place and a strong track record of security.
Monitor network activity. Companies should monitor their networks for suspicious activity, such as unusual network traffic or unauthorized access attempts.
Implement security protocols and training. Businesses should implement strong security protocols and train employees on how to identify and respond to potential cyber threats.
Supply chain attacks, including software supply chain attacks, pose a serious threat to all businesses and individuals. These attacks can be difficult to detect and prevent, but by taking proactive steps to improve security, companies can reduce their risk of falling victim to an attack.
