On July 19th, CrowdStrike released a sensor configuration update to Windows systems.
This configuration update triggered a logic error resulting in a system crash and blue screen (BSOD) on impacted systems.
According to CrowStrike, this issue is not the result of or related to a cyberattack.
In the wake of the recent global outage, cybersecurity firm CrowdStrike has issued a warning about a surge in phishing and fraud attempts. As systems were disrupted and services went down, cybercriminals wasted no time exploiting the chaos to launch a wave of attacks. These malicious actors are taking advantage of the confusion and urgency created by the outage to trick people.
Phishing attempts are becoming increasingly sophisticated, making it difficult for even tech-savvy individuals to distinguish between legitimate and fraudulent communications.

- Sending phishing emails posing as CrowdStrike support to customers
- Impersonating CrowdStrike staff in phone calls
- Posing as independent researchers, claiming to have evidence the technical issue is linked to a cyberattack and offering remediation insights
- Selling scripts purporting to automate recovery from the content update issue
