FortiGuard Labs encountered recent samples of a DDoS-as-a-service botnet calling itself Condi. It attempted to spread by exploiting TP-Link Archer AX21 (AX1800) routers vulnerable to CVE-2023-1389, which was disclosed in mid-March of this year. Read more.

Akamai researchers have identified a new Magecart-style skimmer campaign that hides behind legitimate website domains to steal PII and credit card information.

A new vulnerability, which we refer to as “Migraine” for its involvement with macOS migration, could allow an attacker with root access to automatically bypass System Integrity Protection (SIP) in macOS and perform arbitrary operations on a device

Endpoint Detection & Response systems (EDR),
delivered by in-house teams or as part of a managed
service, are a feature of modern intrusion detection
and remediation operations. This success is a problem
for attackers, and malicious actors have worked to
find new ways to evade EDR detection capabilities.

The next post in our XNU memory safety series examines how our hardened kernel allocator performs in the real world against a previously patched but powerful UAF software vulnerability. In this detailed analysis, we find out what might happen if SockPuppet were to meet kalloc_type in iOS 16.

In this blog post, we will provide details on a BlackCat ransomware incident that occurred in February 2023, where we observed a new capability, mainly used for the defense evasion phase.

This blog post seeks to draw out some high-level trends and anomalies based on our ongoing tracking of QakBot command and control (C2) infrastructure. By looking at the data with a broader scope, we hope to supplement other research into this particular threat family, which in general focuses on specific infrastructure elements; e.g., daily alerting on active C2 servers.

We’re sharing our latest research and analysis into malware campaigns that are targeting online businesses — including newer malware posing as AI tools.

WithSecure Intelligence identified attacks which occurred in late March 2023 against internet-facing servers running Veeam Backup & Replication software. Our research indicates that the intrusion set used in these attacks has overlaps with those attributed to the FIN7 activity group. It is likely that initial access & execution was achieved through a recently patched Veeam Backup & Replication vulnerability, CVE-2023-27532.

• Check Point Research (CPR) and Check Point Incident Response Team (CPIRT) encountered a previously unnamed ransomware strain, we dubbed Rorschach, deployed against a US-based company.
  Rorschach ransomware appears to be unique, sharing no overlaps that could easily attribute it to any known ransomware strain. In addition, it does not bear any kind of branding which is a common practice among ransomware groups.
• The ransomware is partly autonomous, carrying out tasks that are usually manually performed during enterprise-wide ransomware deployment, such as creating a domain group policy (GPO). In the past, similar functionality was linked to LockBit 2.0.
• The ransomware is highly customizable and contains technically unique features, such as the use of direct syscalls, rarely observed in ransomware. Moreover, due to different implementation methods, Rorschach is one of the fastest ransomware observed, by the speed of encryption.
• The ransomware was deployed using DLL side-loading of a Cortex XDR Dump Service Tool, a signed commercial security product, a loading method which is not commonly used to load ransomware. The vulnerability was properly reported to Palo Alto Networks.

In this blog entry, we provide technical details and analysis on the 3CX attacks as they happen. We also discuss available solutions which security teams can maximize for early detection and mitigate the impact of 3CX attacks.

We discovered a new malware, which we named “OpcJacker” (due to its opcode configuration design and its cryptocurrency hijacking ability), that has been distributed in the wild since the second half of 2022.

Another day, another ransomware gang. The Dark Power ransomware gang is new on the block, and is trying to make a name for itself. This blog dives into the specifics of the ransomware used by the gang, as well as some information regarding their victim naming and shaming website, filled with non-paying victims and stolen data.

In 2018, EFF along with researchers from Lookout Security published a report describing the Advanced Persistent Threat (APT) we dubbed "Dark Caracal." Now we have uncovered a new Dark Caracal campaign operating since March of 2022, with hundreds of infections across more than a dozen countries. In this report we will present evidence that the cyber mercenary group Dark Caracal is still active and continues to be focused on Latin America, as was reported last year. We have discovered that Dark Caracal, using the Bandook spyware, is currently infecting over 700 computers in Central and South America, primarily in The Dominican Republic and Venezuela.

We discovered an active campaign targeting Eastern Europeans in the cryptocurrency industry using fake job lures.

As part of our research into the cryptomining botnet kmsdbot, we rendered it useless.

At the end of November 2022, OpenAI released ChatGPT, the new interface for its Large Language Model (LLM), which instantly created a flurry of interest in AI and its possible uses. However, ChatGPT has also added some spice to the modern cyber threat landscape as it quickly became apparent that code generation can help less-skilled threat actors effortlessly launch cyberattacks.

In Check Point Research’s (CPR) previous blog, we described how ChatGPT successfully conducted a full infection flow, from creating a convincing spear-phishing email to running a reverse shell, capable of accepting commands in English. The question at hand is whether this is just a hypothetical threat or if there are already threat actors using OpenAI technologies for malicious purposes.

CPR’s analysis of several major underground hacking communities shows that there are already first instances of cybercriminals using OpenAI to develop malicious tools. As we suspected, some of the cases clearly showed that many cybercriminals using OpenAI have no development skills at all. Although the tools that we present in this report are pretty basic, it’s only a matter of time until more sophisticated threat actors enhance the way they use AI-based tools for bad.

BMC&C Eclypsium Research has discovered and reported 3 vulnerabilities in American Megatrends, Inc. (AMI) MegaRAC Baseboard Management Controller (BMC) software. We are referring to these vulnerabilities collectively as BMC&C. MegaRAC BMC is widely used by many leading server manufacturers to provide “lights-out” management capabilities for their server products. Server manufacturers…

The Wi-Peep exploit allows an attacker to covertly locate all of the Wi-Fi-enabled devices in a building quickly using inexpensive hardware.

Black Basta operational TTPs are described here in full detail, revealing previously unknown tools and techniques and a link to FIN7.
