| Responsible Organization | 1. Chinese government-backed hackers, specifically a group known as Hafnium, were responsible for the software failure incident [112241, 117452]. 2. Chinese state-sponsored hacking group, Hafnium, was behind the aggressive hacking campaign targeting Microsoft email services [117452]. 3. Chinese hackers, including a group known as APT10, were responsible for the cyberattacks on Microsoft Exchange email server software [112301]. 4. Chinese military officials, specifically five Chinese army officials, were accused of cyber-espionage and hacking into U.S. companies [27177]. 5. Chinese army officials from People's Liberation Army Unit 61398 were accused of cyber-espionage and hacking into U.S. companies [27177]. |
| Impacted Organization | 1. US Steel Corp., Westinghouse, Alcoa, Allegheny Technologies, SolarWorld, and the United Steelworkers Union were targeted by the cyber-espionage attack [27177]. 2. At least 30,000 Microsoft customers, including businesses and government agencies in the United States, were impacted by the aggressive hacking campaign attributed to the Chinese government [117452]. |
| Software Causes | 1. The failure incident was caused by vulnerabilities in Microsoft Exchange Server software that were exploited by a Chinese state-sponsored hacking group [112241]. 2. The hackers exploited zero-day vulnerabilities in Exchange Server, allowing them to access email servers without a password and steal emails, install malware, and continue surveillance of their targets [117452]. 3. The initial breach was discovered in January, with the attackers escalating their efforts in recent weeks as Microsoft moved to repair the vulnerabilities [117452]. 4. The attack affected a large number of targets, estimated to be in the tens of thousands, including businesses, government agencies, small businesses, local governments, and military contractors [117452]. 5. The hackers targeted a broad range of victims, from small businesses to local and state governments, and some military contractors, using the vulnerabilities in Exchange Server [117452]. 6. Microsoft identified the Chinese hacking group Hafnium as the state-sponsored group behind the attack, but other hackers not affiliated with Hafnium also exploited the vulnerabilities to target organizations that had not patched their systems [117452]. 7. The attack was considered an aggressive hacking campaign sponsored by the Chinese government, with estimates of around 30,000 Microsoft customers being affected [117452]. 8. The vulnerabilities exploited by the hackers were previously unknown to Microsoft, making it a challenging situation for organizations to patch their systems and protect themselves from the attack [117452]. |
| Non-software Causes | 1. The failure incident was caused by a state-sponsored Chinese hacking group known as Hafnium, which targeted Microsoft email services [117452]. 2. The hackers exploited vulnerabilities in Microsoft Exchange Server software, allowing them to access email servers without a password and steal emails, install malware, and continue surveillance of their targets [117452]. 3. The attack escalated in late February as the hackers began weaving multiple vulnerabilities together and attacking a broader group of victims, including small businesses, local governments, and large credit unions [117452]. 4. The hackers exploited zero-day vulnerabilities in Exchange Server software that were previously unknown to Microsoft, making it challenging for organizations to defend against the attack [117452]. |

| Duration | temporary | The software failure incident related to the Microsoft Exchange Server hack was temporary. The hackers exploited vulnerabilities in Exchange Server software, leading to an aggressive hacking campaign affecting tens of thousands of victims in the United States [Article 117452]. The attack escalated in recent weeks as Microsoft moved to repair the vulnerabilities exploited by the hackers [Article 117452]. The U.S. government issued an emergency warning urging federal agencies to immediately patch their systems to address the widespread exploitation of Microsoft Exchange Server vulnerabilities [Article 117452]. The attack was detected in January and escalated in late February, with the hackers targeting a broad range of victims, including small businesses, local governments, and military contractors [Article 117452]. The hackers were able to steal emails and install malware to continue surveillance of their targets [Article 117452]. The attack was attributed to a Chinese hacking group known as Hafnium, assessed to be state-sponsored and operating out of China [Article 117452]. Additionally, other hackers not affiliated with Hafnium began exploiting the vulnerabilities to target organizations that had not patched their systems [Article 117452]. |
| Behaviour | crash, omission, value, other | (a) crash: The software failure incident related to the Microsoft Exchange Server vulnerabilities can be categorized as a crash. The hackers exploited vulnerabilities in Exchange, causing the system to crash and allowing unauthorized access to email servers without a password. This led to the compromise of tens of thousands of victims in the United States alone [Article 117452]. (b) omission: The software failure incident can also be categorized as an omission. The hackers exploited a bug that allowed them to access email servers without a password, indicating an omission in the system's security measures that should have prevented unauthorized access [Article 117452]. (c) timing: The software failure incident can be categorized as a timing failure. The attack escalated in late February as Microsoft moved to repair the vulnerabilities exploited by the hackers. The timing of the attack coincided with the release of patches by Microsoft, indicating a strategic timing by the hackers to exploit the vulnerabilities [Article 117452]. (d) value: The software failure incident can be categorized as a value failure. The hackers were able to steal emails and install malware to continue surveillance of their targets, indicating a failure in the system's ability to protect sensitive data and prevent unauthorized access [Article 117452]. (e) byzantine: The software failure incident can be categorized as a byzantine failure. The attack involved multiple vulnerabilities being woven together and exploited by the hackers, leading to inconsistent responses and interactions within the system. The attack escalated as the hackers combined and chained exploits, creating a complex and erratic behavior within the compromised systems [Article 117452]. (f) other: The software failure incident can be categorized as a failure due to system behaving in a way not described in the options (a to e). The attack involved stealthy exploitation of vulnerabilities, escalation of the attack, and targeting a broad range of victims, indicating a multifaceted and sophisticated behavior by the hackers that may not fit neatly into the predefined categories of failure behaviors [Article 117452]. |
