In this Threat Analysis report, Cybereason investigates the Ransomware-as-a-Service (RaaS) known as Beast and how to defend against it through the Cybereason Defense Platform.
It affected (before patching) all currently-maintained branches, and recently was highlighted by CISA as being exploited-in-the-wild.
This must be the first time real-world attackers have reversed a patch, and reproduced a vulnerability, before some dastardly researchers released a detection artefact generator tool of their own. /s
At watchTowr's core, we're all about identifying and validating ways into organisations - sometimes through vulnerabilities in network border appliances - without requiring such luxuries as credentials or asset lists.

The difficult part of the initial response to a human-operated ransomware attack is identifying the attack vector. You may already know from recent security incident trends that the vulnerabilities of VPN devices are likely to be exploited, but it often...
Kryptina's adoption by Mallox affiliates complicates malware tracking as ransomware operators blend different codebases into new variants.
It lets attackers control Macs remotely.
CVE-2024-29847 Ivanti Endpoint Manager AgentPortal Deserialization of Untrusted Data Remote Code Execution Vulnerability.
Uncover the secrets of the Quad7 botnet and its ever-evolving toolset. Learn about the new backdoors and protocols used by these operators.
Every sysadmin is familiar with Veeam’s enterprise-oriented backup solution, ‘Veeam Backup & Replication’. Unfortunately, so is every ransomware operator, given it's somewhat 'privileged position' in the storage world of most enterprise's networks. There's no point deploying cryptolocker malware on a target unless you can also deny access to backups, and so, this class of attackers absolutely loves to break this particular software.
With so many eyes focussed on it, then, it is no huge surprise that it has a rich history of CVEs. Today, we're going to look at the latest episode - CVE-2024-40711.
Well, that was a complex vulnerability, requiring a lot of code-reading! We’ve successfully shown how multiple bugs can be chained together to gain RCE in a variety of versions of Veeam Backup & Replication.
This post is about sandbox evasion techniques and their usefulness in more targeted engagements.
There's a lot of sandbox evasion techniques, some are simple: query WMI, some are cool: parsing SMBIOS tables, most try to detect sandbox artifacts. I wanted to know if these techniques are still effective for detecting sandboxes, or if the sandboxes have since been updated to counter them.
Ontinue Cyber Defenders have observed an uptick in activities related to the LummaC2 infostealer being used as a Malware-as-a-Service.
In early July 2024, the Sentinel Labs researchers released an extensive article1 about “FIN7 reboot” tooling, notably introducing “AvNeutralizer”, an anti-EDR tool. This tool has been found in the wild as a packed payload.
In this article, we offer a thorough analysis of the associated private packer that we named “PackXOR”, as well as an unpacking tool. Additionally, while investigating the packer usage, we determined that PackXOR might not be exclusively leveraged by FIN7.
We have examined the Windows TCP/IP network stack flaw that could grant adversaries remote access with maximum privileges. Exploiting CVE-2024–38063 does not imply any action on the part of the user…
We provide a technical analysis on how CVE-2023-22527 can be exploited by malicious actors for cryptojacking attacks that can spread across the victim’s system.
Discover the latest insights on the emerging ransomware group Cicada3301, first detected in June 2024. Truesec's investigation reveals key findings about this group, named after a famous cryptography game, now targeting multiple victims.
Imagine this: an OpenSSH backdoor is discovered, maintainers rush to push out a fixed release package, security researchers trade technical details on mailing lists to analyze the backdoor code. Speculation abounds on the attribution and motives of the attacker, and the tech media pounces on the story. A near miss of epic proportions, a blow to the fabric of trust underlying open source development, a stark reminder of the risks of supply-chain attacks. Equal measures brilliant and devious.

Cado Security has identified a malware-as-a-service (MaaS) targeting macOS users named “Cthulhu Stealer”.
Looking into the abuse of ITarian RMM and introducing Dolphin Loader
people frequently reach out to me with companies to look into. usually it takes me about 10 minutes before i move on for one reason or another—it's not interesting for a story or has good security, for example. i didnt expect anything different when an acquaintance told me about Tracki, a self-proclaimed "world leader in GPS tracking" that they suspected could be used nefariously.
at first glance, Tracki appeared to be a serious company, maybe even one that cared about security. we could never have guessed what was about to unfold before us.
half a year into our investigation, we'd found it all: a hidden conglomerate posing as five independent companies, masked from governments and customers alike through the use of dozens of false identities, US letterbox companies, and an undeclared owner. a 90s phone sex scheme that, through targeting by one of hollywood's most notorious fixers, spiraled into a collection of almost a hundred domains advertising everything from online dating to sore throat remedies. a slew of device-assisted murder cases, on top of potential data breaches affecting almost 12 million users, ranging from federal government officials to literal infants. and most importantly, a little-known Snoop Dogg song. how in the world did we get here?
