Black Kingdom ransomware

securelist.com/black-kingdom-ransomware/102873/ Black Kingdom ransomware appeared on the scene back in 2019, but we observed some activity again in 2021. The ransomware was used by an unknown adversary for exploiting a Microsoft Exchange vulnerability (CVE-2021-27065). The complexity and sophistication of the Black Kingdom family cannot bear a comparison with other Ransomware-as-a-Service (RaaS) or Big Game Hunting (BGH) families. The ransomware is coded in Python and compiled to an executable using PyInstaller; it supports two encryption modes: one generated dynamically and one using a hardcoded key.. Code analysis revealed an amateurish development cycle and a possibility to recover files encrypted with Black Kingdom with the help of the hardcoded key. The industry already provided a script to recover encrypted files in case they were encrypted with the embedded key.

OSINT 101: What is open source intelligence and how is it used?

www.welivesecurity.com/2021/06/16/osint-101-what-is-open-source-intelligence-how-is-it-used/ The cybersecurity industry often gets obsessed with technology: the latest exploits, hacking tools and threat hunting software. In reality, a lot comes down to people. Its people who develop malware, people that hit the red button to launch attacks and, on the other side, people who are tasked with defending against them. To this end, OSINT, or open source intelligence, is an important but often overlooked human element of cybersecurity.. The bottom line is that whatever you can find out online about your organization, so can the bad actors. That thought alone should drive ongoing OSINT efforts to mitigate cyber-risk.

NSA Releases Guidance on Securing Unified Communications and Voice and Video over IP Systems

www.nsa.gov/News-Features/Feature-Stories/Article-View/Article/2661746/nsa-releases-guidance-on-securing-unified-communications-and-voice-and-video-ov/ NSA released a Cybersecurity Technical Report today that provides best practices and mitigations for securing Unified Communications (UC) and Voice and Video over IP (VVoIP) call-processing systems. The comprehensive report, Deploying Secure Unified Communications/Voice and Video over IP Systems, also describes potential risks to UC/VVoIP systems that arent properly secured. To complement the larger report, NSA published an abridged Cybersecurity Information Sheet to capture key takeways and introduce the steps organizations should take when securing their UC/VVoIP systems.

New TA402 Molerats Malware Targets Governments in the Middle East

www.proofpoint.com/us/blog/threat-insight/new-ta402-molerats-malware-targets-governments-middle-east Proofpoint researchers identified a malware called LastConn distributed by TA402, a threat actor also known as Molerats. The malware targeted government institutions in the Middle East and global government organizations associated with geopolitics in the region.

In campaigns identified throughout 2021, TA402 leveraged Middle Eastern geopolitical themes including ongoing conflict in the Gaza Strip.

What you need to know about Process Ghosting, a new executable image tampering attack

www.elastic.co/blog/process-ghosting-a-new-executable-image-tampering-attack Security teams defending Windows environments often rely on anti-malware products as a first line of defense against malicious executables. Microsoft provides security vendors with the ability to register callbacks that will be invoked upon the creation of processes on the system. Driver developers can call APIs such as PsSetCreateProcessNotifyRoutineEx to receive such events. Despite the name, PsSetCreateProcessNotifyRoutineEx callbacks are not actually invoked upon the creation of processes, but rather upon the creation of the first threads within those processes. This creates a gap between when a process is created and when security products are notified of its creation.

A New Spyware is Targeting Telegram and Psiphon VPN Users in Iran

thehackernews.com/2021/06/a-new-spyware-is-targeting-telegram-and.html Threat actors with suspected ties to Iran have been found to leverage instant messaging and VPN apps like Telegram and Psiphon to install a Windows remote access trojan (RAT) capable of stealing sensitive information from targets’ devices since at least 2015. Russian cybersecurity firm Kaspersky, which pieced together the activity, attributed the campaign to an advanced persistent threat (APT) group it tracks as Ferocious Kitten, a group that has singled out Persian-speaking individuals allegedly based in the country while successfully operating under the radar.

Network Forensics on Azure VMs (Part #1)

isc.sans.edu/forums/diary/Network+Forensics+on+Azure+VMs+Part+1/27536/ The tooling to investigate a potentially malicious event on an Azure Cloud VM is still in its infancy. We have covered before (Forensicating Azure VMs) how we can create a snapshot of the OS disk of a running VM. Snapshotting and then killing off the infected VM is very straight forward, but it also tips off an intruder that he has been found out. Sometimes, it makes sense to first watch for a while, and learn more, for example about compromised accounts, lateral movement, or other involved hosts.

Hiccup in Akamais DDoS Mitigation Service Triggers Massive String of Outages

threatpost.com/hiccup-akamais-ddos-outages/167004/ Major financial institutions, airlines and the Hong Kong stock exchange were knocked offline by a backfiring distributed denial-of-service (DDoS) mitigation service Thursday.

Polazert Trojan using poisoned Google Search results to spread

blog.malwarebytes.com/awareness/2021/06/polazert-trojan-using-poisoned-google-search-results-to-spread/ Trojan.Polazert aka SolarMarker has gone back and fine-tuned an old tactic known as SEO-poisoning to plant their Remote Access Trojan (RAT) on as many systems as possible. This RAT runs in memory and is used by attackers to install additional malware on affected systems. Trojan.Polazert is specifically designed to steal credentials from browsers and provide an attacker with a backdoor that allows them to further compromise infected systems. To achieve this, collected data is sent to a C&C server.

Ransomware Operators’ Strategies Evolve as Attacks Rise

beta.darkreading.com/attacks-breaches/ransomware-operators-strategies-evolve-as-attacks-rise Corporate email inboxes remain a valuable target for many cybercriminals, but ransomware operators are finding new avenues into enterprise networks as defensive tools improve, new research shows. Ransomware attackers have begun to leverage criminal organizations, mostly banking Trojan distributors, for malware deployment. These so-called “access facilitators” distribute backdoors to victims using malicious links and attachments sent via email. Once they infiltrate a target, the attackers can sell their access to ransomware groups for a cut of the profit, Proofpoint reports.
