Open-Source Stealer Widely Abused by Threat Actors
The threat of InfoStealers is widespread and has been frequently employed by various Threat Actors (TA)s to launch attacks and make financial gains. Until now, the primary use of stealers by TAs has been to sell logs or to gain initial entry into a corporate network.

L'uso di piattaforme didattiche fornite da Google e Microsoft nelle scuole italiane solleva interrogativi sullo scambio di dati con gli Stati Uniti, al centro di un braccio di ferro tra Washington e la Commissione europea. E per il ministero dell'Istruzione il problema è delle scuole
Google’s Threat Analysis Group (TAG) tracks actors involved in information operations (IO), government backed attacks and financially motivated abuse. For years, TAG has been tracking the activities of commercial spyware vendors to protect users. Today, we actively track more than 30 vendors with varying levels of sophistication and public exposure selling exploits or surveillance capabilities to government backed actors. These vendors are enabling the proliferation of dangerous hacking tools, arming governments that would not be able to develop these capabilities in-house. While use of surveillance technologies may be legal under national or international laws, they are often found to be used by governments to target dissidents, journalists, human rights workers and opposition party politicians.
Vulkan engineers have worked for Russian military and intelligence agencies to support hacking operations, prepare for attacks on infrastructure and spread disinformation
The 3CX VoIP Desktop Application has been compromised to deliver malware via legitimate 3CX updates. Huntress has been investigating this incident and working to validate and assess the current supply chain threat to the security community.
A security issue arose on Update 7, version numbers 18.12.407 & 18.12.416 only for our Electron Windows App. Check this post for more info.

A digitally signed and trojanized version of the 3CX Voice Over Internet Protocol (VOIP) desktop client is reportedly being used to target the company's customers in an ongoing supply chain attack.
A Trojanized version of the popular VOIP/PBX software is in the news; here’s what hunters and defenders are doing
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.
In response to the growing public attention given to ChatGPT, the Europol Innovation Lab organised a number of workshops with subject matter experts from across Europol to explore how criminals can abuse large language models (LLMs) such as ChatGPT, as well as how it may assist investigators in their daily work.
This guide provides steps organizations can take to assess whether users have been targeted or compromised by threat actors exploiting CVE-2023-23397.
The government of France has banned TikTok – and all other recreational apps – from phones issued to its employees.
The nation's ministère de la transformation et de la fonction publiques last Friday issued a statement PDF announcing the policy, which minister of transformation and public service Stanislas Guerini justified on grounds that no recreational apps have sufficiently robust security for them to be deployed on government-owned devices.
QakBot is a banking trojan that has been evolving since its first version was discovered in 2008. According to the 2022 report published by CISA, it was one of the most active variants in 2021, and during 2022 and so far in 2023 it has remained quite active. Taking a brief look at the latests news of QakBot it has been updating its tactics constantly, for example, using a Windows zero-day to avoid displaying the MoTW or the most recent one, using OneNote files to drop QakBot.
In this case we are particularly interested in the anti-analysis techniques used by QakBot during the early stages of its execution. These techniques can make malware analysis harder if they are not known, so learning to identify and bypass them is essential to get to see the malware’s operation at its full potential. Furthermore, there are techniques that can replicate / adopt different types of malware, so knowking them opens the door to the study of different samples.
Uptycs has already identified three Windows-based malware families that use Telegram this year, including Titan Stealer, Parallax RAT, and HookSpoofer. Attackers are increasingly turning to it, particularly for stealer command and control (C2).
And now the Uptycs threat research team has discovered a macOS stealer that also controls its operations over Telegram. We’ve dubbed it MacStealer.
The National Crime Agency has today revealed that it has infiltrated the online criminal marketplace by setting up a number of sites purporting to offer DDoS-for-hire services.
Today’s announcement comes after the Agency chose to identify one of the sites currently being run by officers as part of a sustained programme of activity to disrupt and undermine DDoS as a criminal service.
As we continue to enhance the security of our cloud, we are going to address the problem of email sent to Exchange Online from unsupported and unpatched Exchange servers. There are many risks associated with running unsupported or unpatched software, but by far the biggest risk is security. Once a version of Exchange Server is no longer supported, it no longer receives security updates; thus, any vulnerabilities discovered after support has ended don’t get fixed. There are similar risks associated with running software that is not patched for known vulnerabilities. Once a security update is released, malicious actors will reverse-engineer the update to get a better understanding of how to exploit the vulnerability on unpatched servers.
