In mid-2022, Mandiant's Managed Defense detected multiple intrusions involving QAKBOT, leading to the deployment of BEACON coupled with other pre-ransomware indicators. This marked Mandiant's initial identification of UNC4393, the primary user of BASTA ransomware. Mandiant has responded to over 40 separate UNC4393 intrusions across 20 different industry verticals. While healthcare organizations have not traditionally been a focus for UNC4393, several breaches in the industry this year indicate a possible expansion of their interests. However, this represents only a fraction of the cluster's victims, with the Black Basta data leak site purporting over 500 victims since inception.
Over the course of this blog post, Mandiant will detail the evolution of UNC4393's operational tactics and malware usage throughout its active lifespan, with a focus on the period following the QAKBOT botnet takedown. We will highlight the cluster's transition from readily available tools to custom malware development as well as its evolving reliance on access brokers and diversification of initial access techniques.

DigiCert will be revoking certificates that did not have proper Domain Control Verification (DCV). Before issuing a certificate to a customer, DigiCert validates the customer’s control or ownership over the domain name for which they are requesting a certificate using one of several methods approved by the CA/Browser Forum (CABF). One of these methods relies on the customer adding a DNS CNAME record which includes a random value provided to them by DigiCert. DigiCert then does a DNS lookup for the domain and verifies the same random value, thereby proving domain control by the customer..
A major company made a staggering $75 million ransomware payment to hackers earlier this year, according to cybersecurity vendor Zscaler.

o you have problems configuring Microsoft's Defender? You might not be alone: Microsoft admitted that whatever it's using for its defensive implementation exacerbated yesterday's Azure instability.
No one has blamed the actual product named "Windows Defender," we must note.
According to Microsoft, the initial trigger event for yesterday's outage, which took out great swathes of the web, was a distributed denial-of-service (DDoS) attack. Such attacks are hardly unheard of, and an industry has sprung up around warding them off.
A cyberattack has hit a blood-donation nonprofit that serves hundreds of hospitals in the southeastern US.
