Malicious Ads Target Cryptocurrency Users With Cinobi Banking Trojan

August 17, 2021Ravie Lakshmanan
A new social engineering-based malvertising campaign targeting Japan has been found to deliver a malicious application that deploys a banking trojan on compromised Windows machines to steal credentials associated with cryptocurrency accounts. The application masquerades as an animated porn game, a reward points application, or a video streaming application, Trend Micro researchers Jaromir Horejsi and Joseph C Chen  said  in an analysis published last week, attributing the operation to a threat actor it tracks as Water Kappa, which was  previously found  targeting Japanese online banking users with the Cinobi trojan by leveraging exploits in Internet Explorer browser. The switch in tactics is an indicator that the adversary is singling out users of web browsers other than Internet Explorer, the researchers added. Water Kappa's latest infection routine commences with malvertisements for either Japanese animated porn games, reward points apps, or video streaming services, with t

Hackers Steal Over $600 Million Worth of Cryptocurrencies from Poly Network

August 11, 2021Ravie Lakshmanan
Hackers have siphoned $611 million worth of cryptocurrencies from a blockchain-based financial network in what's believed to be one of the largest heists targeting the digital asset industry, putting it ahead of breaches targeting exchanges Coincheck and Mt. Gox in recent years. Poly Network, a China-based cross-chain decentralized finance (DeFi) platform for swapping tokens across multiple blockchains such as Bitcoin and Ethereum, on Tuesday  disclosed  unidentified actors had exploited a vulnerability in its system to plunder thousands of digital tokens such as Ether. "The hacker exploited a vulnerability between contract calls," Poly Network said.  The stolen Binance Chain, Ethereum, and Polygon assets are said to have been transferred to three different wallets, with the company urging miners of affected blockchain and centralized crypto exchanges to blocklist tokens coming from the addresses. The three wallet addresses are as follows -  Ethereum: 0xC8a65Fadf

Researchers Warn of Linux Cryptojacking Attackers Operating from Romania

July 19, 2021Ravie Lakshmanan
A threat group likely based in Romania and active since at least 2020 has been behind an active cryptojacking campaign targeting Linux-based machines with a previously undocumented SSH brute-forcer written in Golang. Dubbed " Diicot brute ," the password cracking tool is alleged to be distributed via a software-as-a-service model, with each threat actor furnishing their own unique API keys to facilitate the intrusions, Bitdefender researchers said in a report published last week. While the goal of the campaign is to deploy Monero mining malware by remotely compromising the devices via brute-force attacks, the researchers connected the gang to at least two  DDoS  botnets, including a  Demonbot  variant called chernobyl and a Perl  IRC bot , with the XMRig mining payload hosted on a domain named mexalz[.]us since February 2021. The Romanian cybersecurity technology company said it began its investigation into the group's hostile online activities in May 2021, leading

Crackonosh virus mined $2 million of Monero from 222,000 hacked computers

June 25, 2021Ravie Lakshmanan
A previously undocumented Windows malware has infected over 222,000 systems worldwide since at least June 2018, yielding its developer no less than 9,000 Moneros ($2 million) in illegal profits. Dubbed " Crackonosh ," the malware is distributed via illegal, cracked copies of popular software, only to disable antivirus programs installed in the machine and install a coin miner package called XMRig for stealthily exploiting the infected host's resources to mine Monero. At least 30 different versions of the malware executable have been discovered between Jan. 1, 2018, and Nov. 23, 2020, Czech cybersecurity software company Avast  said  on Thursday, with a majority of the victims located in the U.S., Brazil, India, Poland, and the Philippines. Crackonosh works by replacing critical Windows system files such as "serviceinstaller.msi" and "maintenance.vbs" to cover its tracks and abuses the  safe mode , which prevents antivirus software from working, to

Crypto-Mining Attacks Targeting Kubernetes Clusters via Kubeflow Instances

June 09, 2021Ravie Lakshmanan
Cybersecurity researchers on Tuesday disclosed a new large-scale campaign targeting Kubeflow deployments to run malicious cryptocurrency mining containers. The campaign involved deploying  TensorFlow  pods on Kubernetes clusters, with the pods running legitimate  TensorFlow images  from the official Docker Hub account. However, the container images were configured to execute rogue commands that mine cryptocurrencies. Microsoft said the deployments witnessed an uptick towards the end of May. Kubeflow  is an open-source machine learning platform designed to deploy machine learning workflows on  Kubernetes , an orchestration service used for managing and scaling containerized workloads across a cluster of machines. The deployment, in itself, was achieved by taking advantage of Kubeflow, which exposes its UI functionality via a dashboard that is deployed in the cluster. In the attack observed by Microsoft, the adversaries used the centralized dashboard as an ingress point to create a

Researchers Link CryptoCore Attacks On Cryptocurrency Exchanges to North Korea

May 24, 2021Ravie Lakshmanan
State-sponsored hackers affiliated with North Korea have been behind a slew of attacks on cryptocurrency exchanges over the past three years, new evidence has revealed. Attributing the attack with "medium-high" likelihood to the Lazarus Group (aka APT38 or Hidden Cobra), researchers from Israeli cybersecurity firm ClearSky said the campaign, dubbed " CryptoCore ," targeted crypto exchanges in Israel, Japan, Europe, and the U.S., resulting in the theft of millions of dollars worth of virtual currencies. The  findings  are a consequence of piecing together artifacts from a series of isolated but similar reports detailed by  F-Secure , Japanese CERT  JPCERT/CC , and  NTT Security  over the past few months. Since emerging on the scene in 2009,  Hidden Cobra  actors have used their offensive cyber capabilities to carry out espionage and cyber cryptocurrency heists against businesses and critical infrastructure. The adversary's targeting aligns with North Korean

FreakOut! Ongoing Botnet Attack Exploiting Recent Linux Vulnerabilities

January 19, 2021Ravie Lakshmanan
An ongoing malware campaign has been found exploiting recently disclosed vulnerabilities in network-attached storage (NAS) devices running on Linux systems to co-opt the machines into an  IRC botnet  for launching distributed denial-of-service (DDoS) attacks and mining Monero cryptocurrency. The attacks deploy a new  malware variant called " FreakOut " by leveraging critical flaws fixed in Laminas Project (formerly Zend Framework) and Liferay Portal as well as an unpatched security weakness in TerraMaster, according to Check Point Research's new analysis published today and shared with The Hacker News. Attributing the malware to be the work of a long-time cybercrime hacker — who goes by the aliases Fl0urite and Freak on HackForums and Pastebin at least since 2015 — the researchers said the flaws —  CVE-2020-28188 ,  CVE-2021-3007 , and  CVE-2020-7961  — were weaponized to inject and execute malicious commands in the server. Regardless of the vulnerabilities exploit

Warning: Cross-Platform ElectroRAT Malware Targeting Cryptocurrency Users

January 05, 2021Ravie Lakshmanan
Cybersecurity researchers today revealed a wide-ranging scam targeting cryptocurrency users that began as early as January last year to distribute trojanized applications to install a previously undetected remote access tool on target systems. Called ElectroRAT by Intezer, the RAT is written from ground-up in Golang and designed to target multiple operating systems such as Windows, Linux, and macOS.  The apps are developed using the open-source Electron cross-platform desktop app framework. "ElectroRAT is the latest example of attackers using Golang to develop multi-platform malware and evade most antivirus engines," the researchers said . "It is common to see various information stealers trying to collect private keys to access victims wallets. However, it is rare to see tools written from scratch and targeting multiple operating systems for these purposes." The campaign, first detected in December, is believed to have claimed over 6,500 victims based on th

Wormable Gitpaste-12 Botnet Returns to Target Linux Servers, IoT Devices

December 15, 2020Ravie Lakshmanan
A new wormable botnet that spreads via GitHub and Pastebin to install cryptocurrency miners and backdoors on target systems has returned with expanded capabilities to compromise web applications, IP cameras, and routers. Early last month, researchers from Juniper Threat Labs documented a crypto-mining campaign called " Gitpaste-12 ," which used GitHub to host malicious code containing as many as 12 known attack modules that are executed via commands downloaded from a Pastebin URL. The attacks occurred during a 12-day period starting from October 15, 2020, before both the Pastebin URL and repository were shut down on October 30, 2020. Now according to Juniper, the  second wave of attacks  began on November 10 using payloads from a different GitHub repository, which, among others, contains a Linux crypto-miner ("ls"), a file with a list of passwords for brute-force attempts ("pass"), and a local privilege escalation exploit for x86_64 Linux systems.

September 10, 2020Swati Khandelwal
Cybercriminals successfully plundered another digital cryptocurrency exchange. European cryptocurrency exchange Eterbase this week disclosed a massive breach of its network by an unknown group of hackers who stole cryptocurrencies worth 5.4 million dollars. Eterbase, which has now entered maintenance mode until the security issue is resolved, described itself as Europe's Premier Digital Asset Exchange. Based in Bratislava, Slovakia, and launched in 2019, Eterbase is a small cryptocurrency exchange platform that focuses on crypto to SEPA integration (via individual IBAN accounts), multi-asset support, and regulatory compliance. On Monday night, malicious threat actors managed to raid six Eterbase's hot wallets for Bitcoin, Ethereum, XRP, Tezos, Algorand, and TRON and transferred the funds into their wallets managed at six rival crypto exchanges, Eterbase reported on its Telegram channel on Tuesday. According to a tweet posted by the affected exchange, Eterbase t

Cybercriminals Are Using Legit Cloud Monitoring Tools As Backdoor

September 09, 2020Ravie Lakshmanan
A cybercrime group that has previously struck Docker and Kubernetes cloud environments has evolved to repurpose genuine cloud monitoring tools as a backdoor to carry out malicious attacks, according to new research. "To our knowledge, this is the first time attackers have been caught using legitimate third party software to target cloud infrastructure," Israeli cybersecurity firm Intezer said in a Tuesday analysis. Using software called Weave Scope , which is used as a visualization and monitoring tool for Docker and Kubernetes services, the TeamTNT threat actor not only mapped the cloud environment of their victims but also executed system commands without having to deploy malicious code on the target server explicitly. TeamTNT has been active at least since late April this year, directing their attacks on misconfigured Docker ports to install a cryptocurrency mining malware and a Distributed Denial-of-Service (DDoS) bot. Then last month , the crypto-mining gan

Undetectable Linux Malware Targeting Docker Servers With Exposed APIs

July 28, 2020Swati Khandelwal
Cybersecurity researchers today uncovered a completely undetectable Linux malware that exploits undocumented techniques to stay under the radar and targets publicly accessible Docker servers hosted with popular cloud platforms, including AWS, Azure, and Alibaba Cloud. Docker is a popular platform-as-a-service (PaaS) solution for Linux and Windows designed to make it easier for developers to create, test, and run their applications in a loosely isolated environment called a container. According to the latest research Intezer shared with The Hacker News, an ongoing Ngrok mining botnet campaign scanning the Internet for misconfigured Docker API endpoints and has already infected many vulnerable servers with new malware. While the Ngrok mining botnet is active for the past two years, the new campaign is primarily focused on taking control over misconfigured Docker servers and exploiting them to set up malicious containers with cryptominers running on the victims' infrastructu

New Android Malware Now Steals Passwords For Non-Banking Apps Too

July 16, 2020Ravie Lakshmanan
Cybersecurity researchers today uncovered a new strain of banking malware that targets not only banking apps but also steals data and credentials from social networking, dating, and cryptocurrency apps—a total of 337 non-financial Android applications on its target list. Dubbed " BlackRock " by ThreatFabric researchers, which discovered the trojan in May, its source code is derived from a leaked version of Xerxes banking malware, which itself is a strain of the LokiBot Android banking trojan that was first observed during 2016-2017. Chief among its features are stealing user credentials, intercepting SMS messages, hijacking notifications, and even recording keystrokes from the targeted apps, in addition to being capable of hiding from antivirus software. "Not only did the [BlackRock] Trojan undergo changes in its code, but also comes with an increased target list and has been ongoing for a longer period," ThreatFabric said. "It contains an important nu

Docker Images Containing Cryptojacking Malware Distributed via Docker Hub

June 25, 2020Ravie Lakshmanan
With Docker gaining popularity as a service to package and deploy software applications, malicious actors are taking advantage of the opportunity to target exposed API endpoints and craft malware-infested images to facilitate distributed denial-of-service (DDoS) attacks and mine cryptocurrencies. According to a report published by Palo Alto Networks' Unit 42 threat intelligence team, the purpose of these Docker images is to generate funds by deploying a cryptocurrency miner using Docker containers and leveraging the Docker Hub repository to distribute these images. "Docker containers provide a convenient way for packaging software, which is evident by its increasing adoption rate," Unit 42 researchers said . "This, combined with coin mining, makes it easy for a malicious actor to distribute their images to any machine that supports Docker and instantly starts using its compute resources towards cryptojacking." Docker is a well-known platform-as-a-servic

Over 700 Malicious Typosquatted Libraries Found On RubyGems Repository

April 16, 2020Ravie Lakshmanan
As developers increasingly embrace off-the-shelf software components into their apps and services, threat actors are abusing open-source repositories such as RubyGems to distribute malicious packages, intended to compromise their computers or backdoor software projects they work on. In the latest research shared with The Hacker News, cybersecurity experts at ReversingLabs revealed over 700 malicious gems — packages written in Ruby programming language — that supply chain attackers were caught recently distributing through the RubyGems repository. The malicious campaign leveraged the typosquatting technique where attackers uploaded intentionally misspelled legitimate packages in hopes that unwitting developers will mistype the name and unintentionally install the malicious library instead. ReversingLabs said the typosquatted packages in question were uploaded to RubyGems between February 16 and February 25, and that most of them have been designed to secretly steal funds by r
