APT28 Hacker Group Targeting Europe, Americas, Asia in Widespread Phishing Scheme

Mar 18, 2024 Cyber Warfare / Malware
The Russia-linked threat actor known as  APT28  has been linked to multiple ongoing phishing campaigns that employ lure documents imitating government and non-governmental organizations (NGOs) in Europe, the South Caucasus, Central Asia, and North and South America. "The uncovered lures include a mixture of internal and publicly available documents, as well as possible actor-generated documents associated with finance, critical infrastructure, executive engagements, cyber security, maritime security, healthcare, business, and defense industrial production," IBM X-Force  said  in a report published last week. The tech company is tracking the activity under the moniker  ITG05 , which is also known as Blue Athena, BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard (formerly Strontium), FROZENLAKE, Iron Twilight, Pawn Storm, Sednit, Sofacy, TA422, and UAC-028. The disclosure comes more than three months after the adversary was spotted using decoys related to the ongoing I

Cybersecurity Agencies Warn Ubiquiti EdgeRouter Users of APT28's MooBot Threat

Feb 28, 2024 Firmware Security / Vulnerability
In a new joint advisory, cybersecurity and intelligence agencies from the U.S. and other countries are urging users of Ubiquiti EdgeRouter to take protective measures, weeks after a botnet comprising infected routers was  felled by law enforcement  as part of an operation codenamed Dying Ember. The botnet, named MooBot, is said to have been used by a Russia-linked threat actor known as APT28 to facilitate covert cyber operations and drop custom malware for follow-on exploitation. APT28, affiliated with Russia's Main Directorate of the General Staff (GRU), is known to be active since at least 2007. APT28 actors have "used compromised EdgeRouters globally to harvest credentials, collect NTLMv2 digests, proxy network traffic, and host spear-phishing landing pages and custom tools," the authorities  said  [PDF]. The adversary's use of EdgeRouters dates back to 2022, with the attacks targeting aerospace and defense, education, energy and utilities, governments, hospita

HUMINT: Diving Deep into the Dark Web

Jul 09, 2024Cybercrime / Dark Web
Discover how cybercriminals behave in Dark Web forums- what services they buy and sell, what motivates them, and even how they scam each other. Clear Web vs. Deep Web vs. Dark Web Threat intelligence professionals divide the internet into three main components: Clear Web - Web assets that can be viewed through public search engines, including media, blogs, and other pages and sites. Deep Web - Websites and forums that are unindexed by search engines. For example, webmail, online banking, corporate intranets, walled gardens, etc. Some of the hacker forums exist in the Deep Web, requiring credentials to enter. Dark Web - Web sources that require specific software to gain access. These sources are anonymous and closed, and include Telegram groups and invite-only forums. The Dark Web contains Tor, P2P, hacker forums, criminal marketplaces, etc. According to Etay Maor, Chief Security Strategist at Cato Networks , "We've been seeing a shift in how criminals communicate and co
A New Age of Hacktivism

A New Age of Hacktivism

Feb 22, 2024 Hacktivism / Information Warfare
In the past 2 years, we have observed a significant surge in hacktivism activity due to ongoing wars and geopolitical conflicts in various regions. Since the war against Ukraine began, we have witnessed a notable mobilization of non-state and state-backed actors alike, forming new groups or joining existing hacker collectives.  We understand hacktivism as a form of computer hacking that is done to further the goals of political or social  activism 1 . While  activism  describes a normal, non-disruptive use of the Internet in order to support a specific cause (online petitions, fundraising, coordinating activities),  hacktivism  includes operations that use hacking techniques with the intent to disrupt but not to cause serious harm (e.g., data theft, website defacements, redirects, Denial-of-Service attacks). Cyber operations that inherit a willingness or intent to cause harm to physical property, severe economic damage or loss of life would be referred to as  cyberterrorism, 2, 3  Th

New 'VietCredCare' Stealer Targeting Facebook Advertisers in Vietnam

New 'VietCredCare' Stealer Targeting Facebook Advertisers in Vietnam

Feb 21, 2024 Malware / Cyber Threat
Facebook advertisers in Vietnam are the target of a previously unknown information stealer dubbed  VietCredCare  at least since August 2022. The malware is "notable for its ability to automatically filter out Facebook session cookies and credentials stolen from compromised devices, and assess whether these accounts manage business profiles and if they maintain a positive Meta ad credit balance," Singapore-headquartered Group-IB  said  in a new report shared with The Hacker News. The end goal of the large-scale malware distribution scheme is to facilitate the takeover of corporate Facebook accounts by targeting Vietnamese individuals who manage the Facebook profiles of prominent businesses and organizations. Facebook accounts that have been successfully seized are then used by the threat actors behind the operation to post political content or to propagate phishing and affiliate scams for financial gain. VietCredCare is offered to other aspiring cybercriminals under the stealer-as

U.S. Government Disrupts Russia-Linked Botnet Engaged in Cyber Espionage

Feb 16, 2024 Botnet / Network Security
The U.S. government on Thursday said it disrupted a botnet comprising hundreds of small office and home office (SOHO) routers in the country that was put to use by the Russia-linked APT28 actor to conceal its malicious activities. "These crimes included vast spear-phishing and similar credential harvesting campaigns against targets of intelligence interest to the Russian government, such as U.S. and foreign governments and military, security, and corporate organizations," the U.S. Department of Justice (DoJ)  said  in a statement. APT28 , also tracked under the monikers BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard (formerly Strontium), FROZENLAKE, Iron Twilight, Pawn Storm, Sednit, Sofacy, and TA422, is  assessed  to be linked to Unit 26165 of Russia's Main Directorate of the General Staff (GRU). It's known to be active since at least 2007. Court documents allege that the attackers pulled off their cyber espionage campaigns by relying on  MooBot , a Mirai

FritzFrog Returns with Log4Shell and PwnKit, Spreading Malware Inside Your Network

Feb 01, 2024 Cyber Attack / Botnet
The threat actor behind a peer-to-peer (P2P) botnet known as  FritzFrog  has made a return with a new variant that leverages the  Log4Shell vulnerability  to propagate internally within an already compromised network. "The vulnerability is exploited in a brute-force manner that attempts to target as many vulnerable Java applications as possible," web infrastructure and security company Akamai said in a report shared with The Hacker News. FritzFrog,  first documented  by Guardicore (now part of Akamai) in August 2020, is a Golang-based malware that primarily targets internet-facing servers with weak SSH credentials. It's known to be active since January 2020. It has  since evolved  to strike healthcare, education, and government sectors as well as improved its capabilities to ultimately deploy cryptocurrency miners on infected hosts, claiming more than 1,500 victims over the years. What's novel about the latest version is the use of the Log4Shell vulnerability a

U.S. Feds Shut Down China-Linked "KV-Botnet" Targeting SOHO Routers

Feb 01, 2024 Cyber Threat / Network Security
The U.S. government on Wednesday said it took steps to neutralize a botnet comprising hundreds of U.S.-based small office and home office (SOHO) routers hijacked by a China-linked state-sponsored threat actor called Volt Typhoon and blunt the impact posed by the hacking campaign. The existence of the botnet, dubbed  KV-botnet , was  first disclosed  by the Black Lotus Labs team at Lumen Technologies in mid-December 2023. The law enforcement effort was  reported  by Reuters earlier this week. "The vast majority of routers that comprised the KV-botnet were Cisco and NetGear routers that were vulnerable because they had reached 'end of life' status; that is, they were no longer supported through their manufacturer's security patches or other software updates," the Department of Justice (DoJ)  said  in a press statement. Volt Typhoon  (aka DEV-0391, Bronze Silhouette, Insidious Taurus, or Vanguard Panda) is the moniker assigned to a China-based adversarial collect
HeadCrab 2.0 Goes Fileless, Targeting Redis Servers for Crypto Mining

HeadCrab 2.0 Goes Fileless, Targeting Redis Servers for Crypto Mining

Feb 01, 2024 Cryptocurrency / Botnet
Cybersecurity researchers have detailed an updated version of the malware  HeadCrab  that's known to target Redis database servers across the world since early September 2021. The development, which comes exactly a year after the malware was first  publicly disclosed  by Aqua, is a sign that the financially-motivated threat actor behind the campaign is actively adapting and refining their tactics and techniques to stay ahead of the detection curve. The cloud security firm  said  that "the campaign has almost doubled the number of infected Redis servers," with an additional 1,100 compromised servers, up from 1,200 reported at the start of 2023. HeadCrab is designed to infiltrate internet-exposed Redis servers and wrangle them into a botnet for illicitly mining cryptocurrency, while also leveraging the access in a manner that allows the threat actor to execute shell commands, load fileless kernel modules, and exfiltrate data to a remote server. While the origins of th

Russian TrickBot Mastermind Gets 5-Year Prison Sentence for Cybercrime Spree

Jan 26, 2024 Cyber Crime / Malware
40-year-old Russian national Vladimir Dunaev has been sentenced to five years and four months in prison for his role in creating and distributing the TrickBot malware, the U.S. Department of Justice (DoJ) said. The development comes nearly two months after  Dunaev pleaded guilty  to committing computer fraud and identity theft and conspiracy to commit wire fraud and bank fraud. "Hospitals, schools, and businesses were among the millions of TrickBot victims who suffered tens of millions of dollars in losses," DoJ  said . "While active, TrickBot malware, which acted as an initial intrusion vector into victim computer systems, was used to support various ransomware variants." Originating as a banking trojan in 2016, TrickBot evolved into a Swiss Army knife capable of delivering additional payloads, including ransomware. Following efforts to take down the botnet, it was absorbed into the Conti ransomware operation in 2022. The cybercrime crew's allegiance to
New CherryLoader Malware Mimics CherryTree to Deploy PrivEsc Exploits

New CherryLoader Malware Mimics CherryTree to Deploy PrivEsc Exploits

Jan 25, 2024 Threat Intelligence / Malware Research
A new Go-based malware loader called  CherryLoader  has been discovered by threat hunters in the wild to deliver additional payloads onto compromised hosts for follow-on exploitation. Arctic Wolf Labs, which discovered the new attack tool in two recent intrusions, said the loader's icon and name masquerades as the legitimate CherryTree note-taking application to dupe potential victims into installing it. "CherryLoader was used to drop one of two privilege escalation tools,  PrintSpoofer  or  JuicyPotatoNG , which would then run a batch file to establish persistence on the victim device," researchers Hady Azzam, Christopher Prest, and Steven Campbell  said . In another novel twist, CherryLoader also packs modularized features that allow the threat actor to swap exploits without recompiling code. It's currently not known how the loader is distributed, but the attack chains examined by the cybersecurity firm show that CherryLoader ("cherrytree.exe") and i

Feds Warn of AndroxGh0st Botnet Targeting AWS, Azure, and Office 365 Credentials

Jan 17, 2024 Botnet / Cloud Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI)  warned  that threat actors deploying the  AndroxGh0st  malware are creating a botnet for "victim identification and exploitation in target networks." A Python-based malware,  AndroxGh0st  was first documented by Lacework in December 2022, with the malware inspiring several  similar tools  like AlienFox, GreenBot (aka Maintance), Legion, and Predator. The cloud attack tool is capable of infiltrating servers vulnerable to known security flaws to access Laravel environment files and steal credentials for high-profile applications such as Amazon Web Services (AWS), Microsoft Office 365, SendGrid, and Twilio. Some of the notable flaws weaponized by the attackers include  CVE-2017-9841  (PHPUnit),  CVE-2021-41773  (Apache HTTP Server), and  CVE-2018-15133  (Laravel Framework). "AndroxGh0st has multiple features to enable SMTP abuse including scanning, exploitat
Remcos RAT Spreading Through Adult Games in New Attack Wave

Remcos RAT Spreading Through Adult Games in New Attack Wave

Jan 16, 2024 Botnet / Malware
The remote access trojan (RAT) known as Remcos RAT has been found being propagated via webhards by disguising it as adult-themed games in South Korea. WebHard, short for  web hard drive , is a popular online file storage system used to upload, download, and share files in the country. While webhards have been used in the past to deliver  njRAT ,  UDP RAT, and DDoS botnet malware , the AhnLab Security Emergency Response Center's (ASEC) latest analysis shows that the technique has been adopted to distribute Remcos RAT. In these attacks, users are tricked into opening booby-trapped files by passing them off as adult games, which, when launched, execute malicious Visual Basic scripts in order to run an intermediate binary named "ffmpeg.exe." This results in the retrieval of Remcos RAT from an actor-controlled server. A sophisticated RAT, Remcos (aka Remote Control and Surveillance) facilitates unauthorized remote control and surveillance of compromised hosts, enablin
8220 Gang Exploiting Oracle WebLogic Server Vulnerability to Spread Malware

8220 Gang Exploiting Oracle WebLogic Server Vulnerability to Spread Malware

Dec 19, 2023 Cryptojacking / Cyber Threat
The threat actors associated with the  8220 Gang  have been observed exploiting a high-severity flaw in Oracle WebLogic Server to propagate their malware. The security shortcoming is  CVE-2020-14883  (CVSS score: 7.2), a remote code execution bug that could be exploited by authenticated attackers to take over susceptible servers. "This vulnerability allows remote authenticated attackers to execute code using a gadget chain and is commonly chained with  CVE-2020-14882  (an authentication bypass vulnerability also affecting Oracle Weblogic Server) or the use of leaked, stolen, or weak credentials," Imperva  said  in a report published last week. The 8220 Gang has a history of  leveraging known security flaws  to distribute cryptojacking malware. Earlier this May, the group was spotted utilizing another shortcoming in Oracle WebLogic servers (CVE-2017-3506, CVSS score: 7.4) to rope the devices into a crypto mining botnet. Recent attack chains documented by Imperva entail t
New KV-Botnet Targeting Cisco, DrayTek, and Fortinet Devices for Stealthy Attacks

New KV-Botnet Targeting Cisco, DrayTek, and Fortinet Devices for Stealthy Attacks

Dec 15, 2023 Botnet / Advanced Persistent Threat
A new botnet consisting of firewalls and routers from Cisco, DrayTek, Fortinet, and NETGEAR is being used as a covert data transfer network for advanced persistent threat actors, including the China-linked threat actor called  Volt Typhoon . Dubbed  KV-botnet  by the Black Lotus Labs team at Lumen Technologies, the malicious network is an amalgamation of two complementary activity clusters that have been active since at least February 2022. "The campaign infects devices at the edge of networks, a segment that has emerged as a soft spot in the defensive array of many enterprises, compounded by the shift to remote work in recent years," the company  said . The two clusters – codenamed KV and JDY – are said to be distinct yet working in tandem to facilitate access to high-profile victims as well as establish covert infrastructure. Telemetry data suggests that the botnet is commandeered from IP addresses based in China. While the bots part of JDY engages in broader scanning
New NKAbuse Malware Exploits NKN Blockchain Tech for DDoS Attacks

New NKAbuse Malware Exploits NKN Blockchain Tech for DDoS Attacks

Dec 15, 2023 Blockchain / Internet of Things
A novel multi-platform threat called  NKAbuse  has been discovered using a decentralized, peer-to-peer network connectivity protocol known as  NKN  (short for New Kind of Network) as a communications channel. "The malware utilizes NKN technology for data exchange between peers, functioning as a potent implant, and equipped with both flooder and backdoor capabilities," Russian cybersecurity company Kaspersky  said  in a Thursday report. NKN, which has over 62,000 nodes, is  described  as a "software overlay network built on top of today's Internet that enables users to share unused bandwidth and earn token rewards." It incorporates a blockchain layer on top of the existing TCP/IP stack. While threat actors are known to take advantage of emerging communication protocols for command-and-control (C2) purposes and evade detection, NKAbuse leverages blockchain technology to conduct distributed denial-of-service (DDoS) attacks and function as an implant inside com
