CyberPeace Alert: Global Disruptions as CrowdStrike Update Triggers Windows BSOD
Overview:
It is worth stating that millions of Windows users around the world are facing the Blue Screen of Death (BSOD) problem that makes systems shutdown or restart. This has been attributed to a CrowdStrike update that was released recently and has impacted many organizations, financial institutions, and government agencies across the globe. Indian airlines have also reported disruptions on X (formerly Twitter), informing passengers about the issue.
Understanding Blue Screen of Death:
Blue Screen errors, also known as black screen errors or STOP code errors, can occur due to critical issues forcing Windows to shut down or restart. You may encounter messages like "Windows has been shut down to prevent damage to your computer." These errors can be caused by hardware or software problems.
Impact on Industries
Some of the large U. S. airlines such as American Airlines, Delta Airlines, and United Airlines had to issue ground stops because of communication problems. Also, several airports on Friday suffered a massive technical issue in check-in kiosks for IndiGo, Akasa Air, SpiceJet, and Air India Express.
The Widespread Issue
The issue seems widespread and is causing disruption across the board as Windows PCs are deployed at workplaces and other public entities like airlines, banks, and even media companies. It has been pointed out that Windows PCs use a special cybersecurity solution from a company called CrowdStrike that seems to be the culprit for this outage, affecting most Windows PC users out there.
Microsoft's Response
The issue was acknowledged by Microsoft and the mitigations are underway. The company in its verified X handle Microsoft 365 status has shared a series information on the latest outage and they are looking into the matter. The issue is under investigation.
In one of the posts from Microsoft Azure, it is mentioned that they have become aware of an issue affecting Virtual Machines (VMs) running Windows Client and Windows Server with the CrowdStrike Falcon agent installed. These VMs may encounter a bug check (BSOD) and become stuck in a restarting state. Their analysis indicates that this issue started approximately at 19:00 UTC on July 18th. They have provided recommendations as follows:
Restore from Backup: In case customers have available backups prior to 19:00 UTC on July 18th, they should recover VM data from the backups. If the customer is using Azure Backup, they can get exact steps on how to restore VM data in the Azure portal. here.
Offline OS Disk Repair: Alternatively, customers can attempt offline repair of the OS disk by attaching an unmanaged disk to the affected VM. Encrypted disks may require additional steps to unlock before repair. Once attached, delete the following file:
Windows/System/System32/Drivers/CrowdStrike/C00000291*.sys
After deletion, reattach the disk to the original VM.
Microsoft Azure is actively investigating additional mitigation options for affected customers. We will provide updates as we gather more information.

Incident Overview
Earlier this week, the Chinese media reported that several ‘Macau’ government websites were hacked, indicating a significant targeted cyberattack. The hacked website includes those of the office of the Secretary for Security, the public security police, the fire services department and the Security Forces Services Bureau. It was reported that the police have launched a criminal investigation to trace the source of the crime. Furthermore, officials believe the source of the intrusion was likely from overseas, and authorities have carried out an emergency response in conjunction with telecommunication operators to restore affected services on a priority basis. The densely populated Macau is a special administrative region on the south coast of China and the cyber attacks on the essential government website of China raise a serious concern.
Response and Mitigation
Macau's authorities carried out an emergency response in collaboration with telecommunication operators to restore regular services as a distributed denial-of-service attack (DDoS) was reported to be carried out on certain government websites which resulted in the inactivity of those several websites. The country's security forces instructed Macau Telecom to investigate the incident and submit a report and improvement plan to prevent similar attacks in the future.
Context and Implications
The hack on the government websites of Macau is not a single incident; rather, it is a part of an increasing pattern of cyberattacks on the region's vital infrastructure. According to a recent report, the frequency of cybercrimes has tripled since 2020, targeting Macau's critical infrastructure, which is worrying. This pattern draws attention to the growing threats that public sector organisations and governments throughout the world confront.
Final Words
In light of such sophisticated attacks targeting vital infrastructure or critical government operations, it is imperative that the country ensure powerful cybersecurity strategies and measures. Implementing robust cybersecurity measures, developing incident response planning, regular security checks, employee training on cyber hygiene, public awareness and capacity building and international collaboration to jointly develop and plan counteract strategies is a crucial step to build safeguards against such cyber threats.
The incident of a cyberattack on the government websites of Macau serves stark reminder of the evolving threats and cybersecurity challenges, it is a serious concern when critical government websites are compromised by malicious actors. It highlights the necessity for continuous vigilance and cybersecurity measures in place to counter such cyber attacks. A comprehensive approach to cybersecurity, the government can enhance their overall cybersecurity posture, establish resilience against such threats in future, and save the functionality of essential government websites.

Executive Summary:
In the context of the recent earthquake in Taiwan, a video has gone viral and is being spread on social media claiming that the video was taken during the recent earthquake that occurred in Taiwan. However, fact checking reveals it to be an old video. The video is from September 2022, when Taiwan had another earthquake of magnitude 7.2. It is clear that the reversed image search and comparison with old videos has established the fact that the viral video is from the 2022 earthquake and not the recent 2024-event. Several news outlets had covered the 2022 incident, mentioning additional confirmation of the video's origin.
Claims:
There is a news circulating on social media about the earthquake in Taiwan and Japan recently. There is a post on “X” stating that,
“BREAKING NEWS :
Horrific #earthquake of 7.4 magnitude hit #Taiwan and #Japan. There is an alert that #Tsunami might hit them soon”.

Fact Check:
We started our investigation by watching the videos thoroughly. We divided the video into frames. Subsequently, we performed reverse search on the images and it took us to an X (formally Twitter) post where a user posted the same viral video on Sept 18, 2022. Worth to notice, the post has the caption-
“#Tsunami warnings issued after Taiwan quake. #Taiwan #Earthquake #TaiwanEarthquake”
The same viral video was posted on several news media in September 2022.
The viral video was also shared on September 18, 2022 on NDTV News channel as shown below.
Conclusion:
To conclude, the viral video that claims to depict the 2024 Taiwan earthquake was from September 2022. In the course of the rigorous inspection of the old proof and the new evidence, it has become clear that the video does not refer to the recent earthquake that took place as stated. Hence, the recent viral video is misleading . It is important to validate the information before sharing it on social media to prevent the spread of misinformation.
Claim: Video circulating on social media captures the recent 2024 earthquake in Taiwan.
Claimed on: X, Facebook, YouTube
Fact Check: Fake & Misleading, the video actually refers to an incident from 2022.
Executive Summary:
A misleading video of a child covered in ash allegedly circulating as the evidence for attacks against Hindu minorities in Bangladesh. However, the investigation revealed that the video is actually from Gaza, Palestine, and was filmed following an Israeli airstrike in July 2024. The claim linking the video to Bangladesh is false and misleading.
Claims:
A viral video claims to show a child in Bangladesh covered in ash as evidence of attacks on Hindu minorities.
Fact Check:
Upon receiving the viral posts, we conducted a Google Lens search on keyframes of the video, which led us to a X post posted by Quds News Network. The report identified the video as footage from Gaza, Palestine, specifically capturing the aftermath of an Israeli airstrike on the Nuseirat refugee camp in July 2024.
The caption of the post reads, “Journalist Hani Mahmoud reports on the deadly Israeli attack yesterday which targeted a UN school in Nuseirat, killing at least 17 people who were sheltering inside and injuring many more.”
To further verify, we examined the video footage where the watermark of Al Jazeera News media could be seen, We found the same post posted on the Instagram account on 14 July, 2024 where we confirmed that the child in the video had survived a massacre caused by the Israeli airstrike on a school shelter in Gaza.
Additionally, we found the same video uploaded to CBS News' YouTube channel, where it was clearly captioned as "Video captures aftermath of Israeli airstrike in Gaza", further confirming its true origin.
We found no credible reports or evidence were found linking this video to any incidents in Bangladesh. This clearly implies that the viral video was falsely attributed to Bangladesh.
Conclusion:
The video circulating on social media which shows a child covered in ash as the evidence of attack against Hindu minorities is false and misleading. The investigation leads that the video originally originated from Gaza, Palestine and documents the aftermath of an Israeli air strike in July 2024.
- Claims: A video shows a child in Bangladesh covered in ash as evidence of attacks on Hindu minorities.
