Hackers Created Rogue VMs to Evade Detection in Recent MITRE Cyber Attack

Hackers Created Rogue VMs to Evade Detection in Recent MITRE Cyber Attack
May 24, 2024 Endpoint Security / Threat Intelligence
The MITRE Corporation has revealed that the cyber attack targeting the not-for-profit company towards late December 2023 by exploiting zero-day flaws in Ivanti Connect Secure (ICS) involved the threat actor creating rogue virtual machines (VMs) within its VMware environment. "The adversary created their own rogue VMs within the VMware environment, leveraging compromised vCenter Server access," MITRE researchers Lex Crumpton and Charles Clancy  said . "They wrote and deployed a JSP web shell (BEEFLUSH) under the vCenter Server's Tomcat server to execute a Python-based tunneling tool, facilitating SSH connections between adversary-created VMs and the ESXi hypervisor infrastructure." The motive behind such a move is to sidestep detection by obscuring their malicious activities from centralized management interfaces like vCenter and maintain persistent access while reducing the risk of being discovered. Details of the attack  emerged  last month when MITRE rev

FBI Seizes BreachForums Again, Urges Users to Report Criminal Activity
May 15, 2024 Data Breach / Cyber Crime
Law enforcement agencies have officially seized control of the notorious  BreachForums  platform, an online bazaar known for peddling stolen data, for the second time within a year. The website ("breachforums[.]st") has been replaced by a seizure banner stating the clearnet cybercrime forum is under the control of the U.S. Federal Bureau of Investigation (FBI).  The operation is the result of a collaborative effort from authorities in Australia, Iceland, New Zealand, Switzerland, the U.K., the U.S., and Ukraine. The FBI has also taken control of the  Telegram channel  operated by Baphomet, who became the administrator of the forum following the  arrest  of his predecessor Conor Brian Fitzpatrick (aka  pompompurin ) in March last year. It's worth noting a prior iteration of BreachForums, hosted at breached.vc/.to/.co and managed by pompompurin, was seized by law enforcement in late June 2023. "This Telegram chat is under the control of the FBI," a message

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike
May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo

Malicious Python Package Hides Sliver C2 Framework in Fake Requests Library Logo

Malicious Python Package Hides Sliver C2 Framework in Fake Requests Library Logo
May 13, 2024 Software Security / Malware
Cybersecurity researchers have identified a malicious Python package that purports to be an offshoot of the  popular requests library  and has been found concealing a Golang-version of the Sliver command-and-control (C2) framework within a PNG image of the project's logo.  The package employing this steganographic trickery is  requests-darwin-lite , which has been downloaded 417 times prior to it being taken down from the Python Package Index (PyPI) registry. Requests-darwin-lite "appeared to be a fork of the ever-popular requests package with a few key differences, most notably the inclusion of a malicious Go binary packed into a large version of the actual requests side-bar PNG logo," software supply chain security firm Phylum  said . The changes have been introduced in the package's setup.py file, which has been configured to decode and execute a Base64-encoded command to gather the system's Universally Unique Identifier ( UUID ), but only after confirming

Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign

Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign
May 09, 2024 Mobile Security / Cyber Attack
Polish government institutions have been targeted as part of a large-scale malware campaign orchestrated by a Russia-linked nation-state actor called  APT28 . "The campaign sent emails with content intended to arouse the recipient's interest and persuade him to click on the link," the computer emergency response team, CERT Polska,  said  in a Wednesday bulletin. Clicking on the link redirects the victim to the domain run.mocky[.]io, which, in turn, is used to redirect to another legitimate site named webhook[.]site, a  free service  that allows developers to inspect data that's being sent via a webhook, in an effort to evade detection. The next step involves the download of a ZIP archive file from webhook[.]site, which contains the Windows Calculator binary that masquerades as a JPG image file ("IMG-238279780.jpg.exe"), a hidden batch script file, and another hidden DLL file ("WindowsCodecs.dll"). Should a victim run the application, the malic

Android Malware Wpeeper Uses Compromised WordPress Sites to Hide C2 Servers

Android Malware Wpeeper Uses Compromised WordPress Sites to Hide C2 Servers
May 01, 2024 Malware / Android
Cybersecurity researchers have discovered a previously undocumented malware targeting Android devices that uses compromised WordPress sites as relays for its actual command-and-control (C2) servers for detection evasion. The malware, codenamed  Wpeeper , is an ELF binary that leverages the HTTPS protocol to secure its C2 communications. "Wpeeper is a typical backdoor Trojan for Android systems, supporting functions such as collecting sensitive device information, managing files and directories, uploading and downloading, and executing commands," researchers from the QiAnXin XLab team  said . The ELF binary is embedded within a repackaged application that purports to be the  UPtodown App Store  app for Android (package name "com.uptodown"), with the APK file acting as a delivery vehicle for the backdoor in a manner that evades detection. The Chinese cybersecurity firm said it discovered the malware after it detected a  Wpeeper artifact  with zero detection on t

New U.K. Law Bans Default Passwords on Smart Devices Starting April 2024

New U.K. Law Bans Default Passwords on Smart Devices Starting April 2024
Apr 30, 2024 IoT Security / Botnet
The U.K. National Cyber Security Centre (NCSC) is calling on manufacturers of smart devices to comply with new legislation that prohibits them from using default passwords, effective April 29, 2024. "The law, known as the  Product Security and Telecommunications Infrastructure act  (or PSTI act), will help consumers to choose smart devices that have been designed to provide ongoing protection against cyber attacks," the NCSC  said . To that end, manufacturers are required to not supply devices that use guessable default passwords, provide a point of contact to report security issues, and state the duration for which their devices are expected to receive important security updates. Default passwords can not only be easily found online, they also act as a vector for threat actors to log in to devices for follow-on exploitation. That said, a unique default password is permissible under the law. The law, which aims to enforce a set of minimum security standards across the b

ToddyCat Hacker Group Uses Advanced Tools for Industrial-Scale Data Theft
Apr 22, 2024 Network Security / Endpoint Security
The threat actor known as  ToddyCat  has been observed using a wide range of tools to retain access to compromised environments and steal valuable data. Russian cybersecurity firm Kaspersky characterized the adversary as relying on various programs to harvest data on an "industrial scale" from primarily governmental organizations, some of them defense related, located in the Asia-Pacific region. "To collect large volumes of data from many hosts, attackers need to automate the data harvesting process as much as possible, and provide several alternative means to continuously access and monitor systems they attack," security researchers Andrey Gunkin, Alexander Fedotov, and Natalya Shornikova  said . ToddyCat was  first documented  by the company in June 2022 in connection with a series of cyber attacks aimed at government and military entities in Europe and Asia since at least December 2020. These intrusions leveraged a passive backdoor dubbed Samurai that allows

Apr 17, 2024 Ransomware / Cyber Espionage
A previously undocumented "flexible" backdoor called  Kapeka  has been "sporadically" observed in cyber attacks targeting Eastern Europe, including Estonia and Ukraine, since at least mid-2022. The findings come from Finnish cybersecurity firm WithSecure, which attributed the malware to the Russia-linked advanced persistent threat (APT) group tracked as  Sandworm  (aka APT44 or Seashell Blizzard). Microsoft is tracking the same malware under the name KnuckleTouch. "The malware [...] is a flexible backdoor with all the necessary functionalities to serve as an early-stage toolkit for its operators, and also to provide long-term access to the victim estate," security researcher Mohammad Kazem Hassan Nejad  said . Kapeka comes fitted with a dropper that's designed to launch and execute a backdoor component on the infected host, after which it removes itself. The dropper is also responsible for setting up persistence for the backdoor either as a schedul
