Singtel, Singapore's multinational telecommunications conglomerate, is another victim of the Accellion data breach that occurred on December 23.\ \ Singtel announced its impact in a [public statement](https://www.singtel.com/personal/support/about-accellion-security-incident). “Singtel has been informed by a third-party vendor Accellion that its file-sharing system called FTA has been illegally attacked by unidentified hackers.” Singtel said in its statement. This incident is part of a wider supply chain attack. Other potential victims include [ASIC](https://www.upguard.com/news/asic-data-breach), Allens, and the [New Zealand Central Bank](https://www.upguard.com/news/new-zealand-central-bank-cyberattack). Investigations are ongoing, but Singtel already suspects that sensitive customer information was compromised.  “We are currently conducting an impact assessment with the utmost urgency to ascertain the nature and extent of data that has been potentially accessed. Customer information may have been compromised.” [Supply chain attacks](https://www.upguard.com/blog/supply-chain-attack) are becoming popular because they make the life of a cyber attacker much easier. Third-party vendors need access to sensitive data in order to integrate with internal systems. Because each vendor stores sensitive data for all of its users, a hacker needs to only compromise a single vendor to impact multiple victims, rather than targeting each victim individually.[‍](https://www.accellion.com/company/press-releases/accellion-provides-update-to-recent-fta-security-incident/) [Accellion has said](https://www.accellion.com/company/press-releases/accellion-provides-update-to-recent-fta-security-incident/) that they have now patched all vulnerabilities, but this is little consolidation to the many victims that need to recover from this breach. Had [the data leaks exposing Accellion](https://www.upguard.com/product/breach-risk/threat-monitoring) been identified earlier, this pernicious domino effect may have been avoided. ## How secure is Accellion? Accellion operates the Kiteworks Private Data Network, a platform that unifies and secures sensitive data exchanges through email, file sharing, managed file transfer, secure forms, and APIs. The company provides encryption, access controls, and compliance management tools designed to help organizations protect confidential information and meet regulatory requirements across government and enterprise sectors. * View our free preliminary report on Accellion’s security posture * 13 risk factors, including email security, SSL, DNS health, open ports and common vulnerabilities [View Accellion's score](/security-report/accellion) [View score](/security-report/accellion) [https://www.accellion.com/](/security-report/accellion) ### Sign up for our newsletter UpGuard's monthly newsletter cuts through the noise and brings you what matters most: our breaking research, in-depth analysis of emerging threats, and actionable strategic insights. ## Latest news Stay up-to-date with the latest news in cybersecurity.
