SPECTR Malware Targets Ukraine Defense Forces in SickSync Campaign

SPECTR Malware Targets Ukraine Defense Forces in SickSync Campaign

Jun 07, 2024 Cyber Attack / Malware
The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of cyber attacks targeting defense forces in the country with a malware called SPECTR as part of an espionage campaign dubbed SickSync. The agency attributed the attacks to a threat actor it tracks under the moniker UAC-0020, which is also called Vermin and is assessed to be associated with security agencies of the Luhansk People's Republic (LPR). LPR was declared a sovereign state by Russia days prior to its military invasion of Ukraine in February 2022. Attack chains commence with spear-phishing emails containing a RAR self-extracting archive file containing a decoy PDF file, a trojanized version of the SyncThing application that incorporates the SPECTR payload, and a batch script that activates the infection by launching the executable. SPECTR serves as an information stealer by grabbing screenshots every 10 seconds, harvesting files, gathering data from removable USB drives, and stealing credentials and ...
Product Walkthrough: How Reco Discovers Shadow AI in SaaS

Product Walkthrough: How Reco Discovers Shadow AI in SaaS

Jan 09, 2025AI Security / SaaS Security
As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...

Celebrity TikTok Accounts Compromised Using Zero-Click Attack via DMs

Jun 05, 2024 Cyber Attack / Online Security
Popular video-sharing platform TikTok has acknowledged a security issue that has been exploited by threat actors to take control of high-profile accounts on the platform. The development was first reported by Semafor and Forbes , which detailed a zero-click account takeover campaign that allows malware propagated via direct messages to compromise brand and celebrity accounts without having to click or interact with it. The exploit has been found to take advantage of a zero-day vulnerability in the messaging component that allows malicious code to be executed as soon as the message is opened. It's currently unclear how many users have been affected, although a TikTok spokesperson said that the company has taken preventive measures to stop the attack and stop it from happening again in the future. The company further said that it's working directly with impacted account holders to restore access and that the attack only managed to compromise a "very small" number...

May 31, 2024 Network Security / Cyber Attack
More than 600,000 small office/home office (SOHO) routers are estimated to have been bricked and taken offline following a destructive cyber attack staged by unidentified cyber actors, disrupting users' access to the internet. The mysterious event, which took place between October 25 and 27, 2023, and impacted a single internet service provider (ISP) in the U.S., has been codenamed Pumpkin Eclipse by the Lumen Technologies Black Lotus Labs team. It specifically affected three router models issued by the ISP: ActionTec T3200, ActionTec T3260, and Sagemcom. "The incident took place over a 72-hour period between October 25-27, rendered the infected devices permanently inoperable, and required a hardware-based replacement," the company said in a technical report. The blackout is significant, not least because it led to the abrupt removal of 49% of all modems from the impacted ISP's autonomous system number (ASN) during the time-frame. While the name of the ISP was...
Microsoft Warns of Surge in Cyber Attacks Targeting Internet-Exposed OT Devices

Microsoft Warns of Surge in Cyber Attacks Targeting Internet-Exposed OT Devices

May 31, 2024 OT Security / Threat Intelligence
Microsoft has emphasized the need for securing internet-exposed operational technology (OT) devices following a spate of cyber attacks targeting such environments since late 2023. "These repeated attacks against OT devices emphasize the crucial need to improve the security posture of OT devices and prevent critical systems from becoming easy targets," the Microsoft Threat Intelligence team said . The company noted that a cyber attack on an OT system could allow malicious actors to tamper with critical parameters used in industrial processes, either programmatically via the programmable logic controller (PLC) or using the graphical controls of the human-machine interface (HMI), resulting in malfunctions and system outages. It further said that OT systems often lack adequate security mechanisms, making them ripe for exploitation by adversaries and carry out attacks that are "relatively easy to execute," a fact compounded by the additional risks introduced by direc...

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...

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...
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 mali...
