New UULoader Malware Distributes Gh0st RAT and Mimikatz in East Asia

Aug 19, 2024 Threat Intelligence / Cryptocurrency

A new type of malware called UULoader is being used by threat actors to deliver next-stage payloads like Gh0st RAT and Mimikatz . The Cyberint Research Team, which discovered the malware, said it's distributed in the form of malicious installers for legitimate applications targeting Korean and Chinese speakers. There is evidence pointing to UULoader being the work of a Chinese speaker due to the presence of Chinese strings in program database (PDB) files embedded within the DLL file. "UULoader's 'core' files are contained in a Microsoft Cabinet archive (.cab) file which contains two primary executables (an .exe and a .dll) which have had their file header stripped," the company said in a technical report shared with The Hacker News. One of the executables is a legitimate binary that's susceptible to DLL side-loading, which is used to sideload the DLL file that ultimately loads the final stage, an obfuscate file named "XamlHost.sys" that&#

Cybercriminals Exploit Popular Software Searches to Spread FakeBat Malware

Aug 19, 2024 Malvertising / Cybercrime

Cybersecurity researchers have uncovered a surge in malware infections stemming from malvertising campaigns distributing a loader called FakeBat. "These attacks are opportunistic in nature, targeting users seeking popular business software," the Mandiant Managed Defense team said in a technical report. "The infection utilizes a trojanized MSIX installer, which executes a PowerShell script to download a secondary payload." FakeBat , also called EugenLoader and PaykLoader, is linked to a threat actor named Eugenfest. The Google-owned threat intelligence team is tracking the malware under the name NUMOZYLOD and has attributed the Malware-as-a-Service (MaaS) operation to UNC4536. Attack chains propagating the malware make use of drive-by download techniques to push users searching for popular software toward bogus lookalike sites that host booby-trapped MSI installers. Some of the malware families delivered via FakeBat include IcedID, RedLine Stealer, Lumma Steale

How to Automate the Hardest Parts of Employee Offboarding

Aug 19, 2024 SaaS Account Management

According to recent research on  employee offboarding , 70% of IT professionals say they've experienced the negative effects of incomplete IT offboarding, whether in the form of a security incident tied to an account that wasn't deprovisioned, a surprise bill for resources that aren't in use anymore, or a missed handoff of a critical resource or account. This is despite an average of five hours spent per departing employee on activities like finding and deprovisioning SaaS accounts. As the SaaS footprint within most organizations continues to expand, it is becoming exponentially more difficult (and time-consuming) to ensure all access is deprovisioned or transferred when an employee leaves the organization.  How Nudge Security can help Nudge Security is a  SaaS management platform  for modern IT governance and security. It discovers every cloud and SaaS account ever created by anyone in your organization, including generative AI apps, giving you a single source of truth for depa

Xeon Sender Tool Exploits Cloud APIs for Large-Scale SMS Phishing Attacks

Aug 19, 2024 Cloud Security / Threat Intelligence

Malicious actors are using a cloud attack tool named Xeon Sender to conduct SMS phishing and spam campaigns on a large scale by abusing legitimate services. "Attackers can use Xeon to send messages through multiple software-as-a-service (SaaS) providers using valid credentials for the service providers," SentinelOne security researcher Alex Delamotte said in a report shared with The Hacker News. Examples of the services used to facilitate the en masse distribution of SMS messages include Amazon Simple Notification Service (SNS), Nexmo, Plivo, Proovl, Send99, Telesign, Telnyx, TextBelt, Twilio. It's important to note here that the activity does not exploit any inherent weaknesses in these providers. Rather, the tool uses legitimate APIs to conduct bulk SMS spam attacks. It joins tools like SNS Sender that have increasingly become a way to send bulk smishing messages and ultimately capture sensitive information from targets. Distributed via Telegram and hacking fo

Microsoft Patches Zero-Day Flaw Exploited by North Korea's Lazarus Group

Aug 19, 2024 Vulnerability / Zero-Day

A newly patched security flaw in Microsoft Windows was exploited as a zero-day by Lazarus Group , a prolific state-sponsored actor affiliated with North Korea. The security vulnerability, tracked as CVE-2024-38193 (CVSS score: 7.8), has been described as a privilege escalation bug in the Windows Ancillary Function Driver (AFD.sys) for WinSock. "An attacker who successfully exploited this vulnerability could gain SYSTEM privileges," Microsoft said in an advisory for the flaw last week. It was addressed by the tech giant as part of its monthly Patch Tuesday update. Credited with discovering and reporting the flaw are Gen Digital researchers Luigino Camastra and Milánek. Gen Digital owns a number of security and utility software brands like Norton, Avast, Avira, AVG, ReputationDefender, and CCleaner. "This flaw allowed them to gain unauthorized access to sensitive system areas," the company disclosed last week, adding it discovered the exploitation in early J

Researchers Uncover New Infrastructure Tied to FIN7 Cybercrime Group

Aug 19, 2024 Cybercrime / Network Security

Cybersecurity researchers have discovered new infrastructure linked to a financially motivated threat actor known as FIN7 . The two clusters of potential FIN7 activity "indicate communications inbound to FIN7 infrastructure from IP addresses assigned to Post Ltd (Russia) and SmartApe (Estonia), respectively," Team Cymru said in a report published this week as part of a joint investigation with Silent Push and Stark Industries Solutions. The findings build on a recent report from Silent Push, which found several Stark Industries IP addresses that are solely dedicated to hosting FIN7 infrastructure. The latest analysis indicates that the hosts linked to the e-crime group were likely procured from one of Stark's resellers. "Reseller programs are common in the hosting industry; many of the largest VPS (virtual private server) providers offer such services," the cybersecurity company said. "Customers procuring infrastructure via resellers generally must

Why Hardsec Matters: From Protecting Critical Services to Enhancing Resilience

Aug 13, 2024Cyber Defense / Compliance

Traditionally, the focus has been on defending against digital threats such as malware, ransomware, and phishing attacks by detecting them and responding. However, as cyber threats become more sophisticated. There is a growing recognition of the importance of measures that stop new attacks before they are recognized. With high-value assets, it's not good enough to have the protection, it's essential to have some assurance that the protection is effective. With software, that assurance is hard work, and this has led to a complimentary approach, called hardsec. What is Hardsec? Short for " Hardware Security ." Hardsec is about using hardware logic and electronics to implement a security defence, rather than through software alone - thereby providing a higher level of security assurance and resilience against both external and insider threats . Making it an essential component of comprehensive cybersecurity strategies. The Rise of Sophisticated Attacks When the impact of an attack ag

OpenAI Blocks Iranian Influence Operation Using ChatGPT for U.S. Election Propaganda

Aug 17, 2024 National Securit / AI Ethics

OpenAI on Friday said it banned a set of accounts linked to what it said was an Iranian covert influence operation that leveraged ChatGPT to generate content that, among other things, focused on the upcoming U.S. presidential election. "This week we identified and took down a cluster of ChatGPT accounts that were generating content for a covert Iranian influence operation identified as Storm-2035," OpenAI said . "The operation used ChatGPT to generate content focused on a number of topics — including commentary on candidates on both sides in the U.S. presidential election – which it then shared via social media accounts and websites." The artificial intelligence (AI) company said the content did not achieve any meaningful engagement, with a majority of the social media posts receiving negligible to no likes, shares, and comments. It further noted it had found little evidence that the long-form articles created using ChatGPT were shared on social media platforms.

Attackers Exploit Public .env Files to Breach Cloud Accounts in Extortion Campaign

Aug 16, 2024 Cloud Security / Application Security

A large-scale extortion campaign has compromised various organizations by taking advantage of publicly accessible environment variable files (.env) that contain credentials associated with cloud and social media applications. "Multiple security missteps were present in the course of this campaign, including the following: Exposing environment variables, using long-lived credentials, and absence of least privilege architecture," Palo Alto Networks Unit 42 said in a Thursday report. The campaign is notable for setting up its attack infrastructure within the infected organizations' Amazon Web Services (AWS) environments and using them as a launchpad for scanning more than 230 million unique targets for sensitive data. With 110,000 domains targeted, the malicious activity is said to have netted over 90,000 unique variables in the .env files, out of which 7,000 belonged to organizations' cloud services and 1,500 variables are linked to social media accounts.

Russian Hacker Jailed 3+ Years for Selling Stolen Credentials on Dark Web

Aug 16, 2024 Dark Web / Data Breach

A 27-year-old Russian national has been sentenced to over three years in prison in the U.S. for peddling financial information, login credentials, and other personally identifying information (PII) on a now-defunct dark web marketplace called Slilpp . Georgy Kavzharadze, 27, of Moscow, Russia, pleaded guilty to one count of conspiracy to commit bank fraud and wire fraud earlier this February. In addition to a 40-month jail term, Kavzharadze has been ordered to pay $1,233,521.47 in restitution. The defendant, who went by the online monikers TeRorPP, Torqovec, and PlutuSS, is believed to have listed over 626,100 stolen login credentials for sale on Slilpp and sold more than 297,300 of them on the illicit marketplace between July 2016 and May 2021. "Those credentials were subsequently linked to $1.2 million in fraudulent transactions," the U.S. Department of Justice (DoJ) said . "On May 27, 2021, Kavzharadze's account on Slilpp listed 240,495 login credentials fo
