New ransomware threat emerges in 2025
A new and unusually dangerous and sophisticated gang of cybercriminals, named BlackLock, has emerged as a major ransomware threat in 2025. Cybersecurity company Reliaquest observed a staggering 1,425 percent increase in the gang’s activities in the last quarter of 2024. Its ransomware is built to target Windows, VMWare ESXi, and Linux environments and is designed as a double-extortion attack, which involves not only locking the target organization’s critical data by encrypting it, but also by identifying sensitive information and threatening to expose it. “BlackLock’s rise has been both swift and strategic, targeting organizations across a wide range of sectors and geographies,” reports Reliaquest.
Latest Microsoft outage ‘triggered’ by a cyber-attack
A second outage of several Microsoft services in two weeks, this one attributed to a cyber-attack, is fuelling further questions about the underlying security of the Windows operating system. According to Microsoft: "While the initial trigger event was a Distributed Denial-of-Service (DDoS) attack... initial investigations suggest that an error in the implementation of our defenses amplified the impact of the attack rather than mitigating it.” Services affected included Outlook, Azure, and Microsoft 365, with some people complaining on social media that they were unable to work. Starbucks customers also reported issues with the Starbucks app in Boston, New York, Washington DC, Dallas, Chicago, Los Angeles, Tampa and other cities. The disruption caused by this latest outage is, however, minor compared with the Windows outage caused by a mishandled CrowdStrike security upgrade, which resulted in canceled flights and marooned passengers in major international airports around the world last week.
Exclusive: CrowdStrike crash is only the beginning…
The famous “blue screen of death,” witnessed with horror by 8.5 million Microsoft Windows users worldwide as a result of the ongoing CrowdStrike outage, may soon become a far more familiar sight across a wide range of sectors. While there is no evidence that the widespread Microsoft Windows outage caused by the CrowdStrike upgrade was anything but accidental, many in the cybersecurity industry are seeing the past week’s experience as a dummy run for a full-fledged cyber-attack aimed at crippling critical infrastructure. As the current media pictures of people sleeping in airports testify, some sectors appear to be faring better than others.
Cybercriminals capitalize on CrowdStrike outage
Organized cybercriminal gangs have lost little time in attempting to cash in on the ongoing CrowdStrike/Windows outage currently affecting banks, airlines and businesses. According to the UK’s National Security Cyber Centre: “An increase in phishing referencing this outage has already been observed, as opportunistic malicious actors seek to take advantage of the situation. This may be aimed at both organizations and individuals.”
