Cisco Talos recently discovered a new ransomware actor called RA Group that has been operating since at least April 22, 2023.

A new ransomware group known as RA Group has become the latest threat actor to leverage the leaked Babuk ransomware source code to spawn its own locker variant. The cybercriminal gang, which is said to have been operating since at least April 22, 2023, is rapidly expanding its operations, according to cybersecurity firm Cisco Talos. "To date, the group has compromised three organizations in the

Government, aviation, education, and telecom sectors located in South and Southeast Asia have come under the radar of a new hacking group as part of a highly-targeted campaign that commenced in mid-2022 and continued into the first quarter of 2023. Symantec, by Broadcom Software, is tracking the activity under its insect-themed moniker Lancefly, with the attacks making use of a "powerful"

A new ransomware-as-service (RaaS) operation called MichaelKors has become the latest file-encrypting malware to target Linux and VMware ESXi systems as of April 2023. The development points to cybercriminal actors increasingly setting their eyes on the ESXi, cybersecurity firm CrowdStrike said in a report shared with The Hacker News. "This trend is especially noteworthy given the fact that ESXi

In KeePass 2.x before 2.54, it is possible to recover the cleartext master password from a memory dump, even when a workspace is locked or no longer running. The memory dump can be a KeePass process dump, swap file (pagefile.sys), hibernation file (hiberfil.sys), or RAM dump of the entire system. The first character cannot be recovered. In 2.54, there is different API usage and/or random string insertion for mitigation.

Cybersecurity researchers have discovered an ongoing phishing campaign that makes use of a unique attack chain to deliver the XWorm malware on targeted systems. Securonix, which is tracking the activity cluster under the name MEME#4CHAN, said some of the attacks have primarily targeted manufacturing firms and healthcare clinics located in Germany. "The attack campaign has been leveraging rather

### Impact Prior to version v1.20230419.0, the FormData API implementation was subject to an integer overflow. If a FormData instance contained more than 2^31 elements, the `forEach()` method could end up reading from the wrong location in memory while iterating over elements. This would most likely lead to a segmentation fault, but could theoretically allow arbitrary undefined behavior. In order for the bug to be exploitable, the process would need to be able to allocate 160GB of RAM. Due to this, the bug was never exploitable on the Cloudflare Workers platform, but could theoretically be exploitable on deployments of workerd running on machines with a huge amount of memory. Moreover, in order to be remotely exploited, an attacker would have to upload a single form-encoded HTTP request of at least tens of gigabytes in size. The application code would then have to use `request.formData()` to parse the request and `formData.forEach()` to iterate over this data. Due to these limitations...

Today, Talos is publishing a glimpse into the most prevalent threats we've observed between May 5 and May 12. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key

Retired hardware and forgotten cloud virtual machines are a trove of insecure confidential data. Here's how to ameliorate that weakness.

One long-awaited security move caused a ripple effect in the cybercrime ecosystem.
