The updated GHOSTPULSE malware has evolved to embed malicious data directly within pixel structures, making it harder to detect and requiring new analysis and detection techniques.

If someone asked me what was the best way to make money from a compromised AWS Account (assume root access even) — I would have answered “dump the data and hope that no-one notices you before you finish it up.”

This answer would have been valid until ~8 months ago when I stumbled upon a lesser known feature of AWS KMS which allows an attacker to do devastating ransomware attacks on a compromised AWS account.

Now I know that ransomware attacks using cross-account KMS keys is already known (checkout the article below)— but even then, the CMK is managed by AWS and they can just block the attackers access to the CMK and decrypt data for the victim because the key is OWNED by AWS and attacker is just given API access to it under AWS TOS. Also there’s no way to delete the CMK but only schedule the key deletion (min 7 days) which means there’s ample time for AWS to intervene.

Version 1.1: October 18, 2024

• Based on our investigations, we are confident that there has been no breach of our systems.
• We have determined that the data in question is on a public-facing * DevHub environment—a Cisco resource center that enables us to support our community by making available software code, scripts, etc. for customers to use as needed.
• At this stage in our investigation, we have determined that a small number of files that were not authorized for public download may have been published.
• As of now, we have not observed any confidential information such as sensitive PII or financial data to be included but continue to investigate to confirm.
• Out of an abundance of caution, we have disabled public access to the site while we continue the investigation.
• Meanwhile, Cisco will engage directly with customers if we determine they have been impacted by this event.

On October 16, 2024, Radiant Capital experienced a security breach resulting in the loss of approximately $50 million USD. The attack compromised three Radiant developers, all of whom are…

The Internet Archive was breached again, this time on their Zendesk email support platform after repeated warnings that threat actors stole exposed GitLab authentication tokens.

Since mid-September 2024, our telemetry has revealed a significant increase in “Lumma Stealer”1 malware deployments via the “HijackLoader”2 malicious loader.

On October 2, 2024, HarfangLab EDR detected and blocked yet another HijackLoader deployment attempt – except this time, the malware sample was properly signed with a genuine code-signing certificate.

In response, we initiated a hunt for code-signing certificates (ab)used to sign malware samples. We identified and reported more of such certificates. This report briefly presents the associated stealer threat, outlines the methodology for hunting these certificates, and providees indicators of compromise.

Two individuals behind the Anonymous Sudan cybercriminal group were indicted by the U.S. Department of Justice, which acknowledged AWS for its contributions.

The United States Department of Justice (DOJ) recently announced the takedown of Anonymous Sudan, a prolific entity in the distributed denial-of-service (DDoS) space who are known especially for their politically motivated hacktivism. This takedown is a huge step toward making the internet a safer place, and it required significant effort from multiple parties, including Akamai.
