Chinese Hackers Distributing SMS Bomber Tool with Malware Hidden Inside

Chinese Hackers Distributing SMS Bomber Tool with Malware Hidden Inside
June 23, 2022Ravie Lakshmanan
A threat cluster with ties to a hacking group called Tropic Trooper has been spotted using a previously undocumented malware coded in Nim language to strike targets as part of a newly discovered campaign. The novel loader, dubbed Nimbda, is "bundled with a Chinese language greyware 'SMS Bomber' tool that is most likely illegally distributed in the Chinese-speaking web," Israeli cybersecurity company Check Point  said  in a report. "Whoever crafted the Nim loader took special care to give it the same executable icon as the SMS Bomber that it drops and executes," the researchers said. "Therefore the entire bundle works as a trojanized binary." SMS Bomber, as the name indicates, allows a user to input a phone number (not their own) so as to flood the victim's device with messages and potentially render it unusable in what's a denial-of-service (DoS) attack. The fact that the binary doubles up as SMS Bomber and a backdoor suggests that t

Europol Busts Phishing Gang Responsible for Millions in Losses
June 22, 2022Ravie Lakshmanan
Europol on Tuesday announced the dismantling of an organized crime group that dabbled in phishing, fraud, scams, and money laundering activities. The cross-border operation, which involved law enforcement authorities from Belgium and the Netherlands, saw the arrests of nine individuals in the Dutch nation. The suspects are men between the ages of 25 and 36 from Amsterdam, Almere, Rotterdam, and Spijkenisse and a 25-year-old woman from Deventer, according to a  statement  from the National Police Force. Also confiscated as part of 24 house searches were firearms, ammunition, jewelry, designer clothing, expensive watches, electronic devices, tens of thousands of euros in cash, and cryptocurrency, the officials said. "The criminal group contacted victims by email, text message and through mobile messaging applications," the agency  noted . "These messages were sent by the members of the gang and contained a phishing link leading to a bogus banking website." Unsu

RIG Exploit Kit Now Infects Victims' PCs With Dridex Instead of Raccoon Stealer

RIG Exploit Kit Now Infects Victims' PCs With Dridex Instead of Raccoon Stealer
June 21, 2022Ravie Lakshmanan
The operators behind the Rig Exploit Kit have swapped the Raccoon Stealer malware for the Dridex financial trojan as part of an ongoing campaign that commenced in January 2022. The switch in modus operandi,  spotted  by Romanian company Bitdefender, comes in the wake of Raccoon Stealer  temporarily closing the project  after one of its team members responsible for critical operations passed away in the Russo-Ukrainian war in March 2022. The Rig Exploit Kit is notable for its abuse of browser exploits to distribute an array of malware. First spotted in 2019, Raccoon Stealer is a credential-stealing trojan that's advertised and sold on underground forums as a malware-as-a-service (MaaS) for $200 a month. That said, the Raccoon Stealer actors are already working on a second version that's expected to be "rewritten from scratch and optimized." But the void left by the malware's exit is being filled by other information stealers such as RedLine Stealer and Vidar.

New NTLM Relay Attack Lets Attackers Take Control Over Windows Domain
June 21, 2022Ravie Lakshmanan
A new kind of Windows NTLM relay attack dubbed  DFSCoerce  has been uncovered that leverages the Distributed File System (DFS): Namespace Management Protocol (MS-DFSNM) to seize control of a domain. "Spooler service disabled, RPC filters installed to prevent PetitPotam and File Server VSS Agent Service not installed but you still want to relay [Domain Controller authentication to [Active Directory Certificate Services]? Don't worry MS-DFSNM have (sic) your back," security researcher Filip Dragovic  said  in a tweet. MS-DFSNM  provides a remote procedure call (RPC) interface for administering distributed file system configurations. The NTLM (NT Lan Manager) relay attack is a well-known method that exploits the challenge-response mechanism. It allows malicious parties to sit between clients and servers and intercept and relay validated authentication requests in order to gain unauthorized access to network resources, effectively gaining an initial foothold in Active Di

Atlassian Confluence Flaw Being Used to Deploy Ransomware and Crypto Miners
June 17, 2022Ravie Lakshmanan
A recently patched  critical security flaw  in Atlassian Confluence Server and Data Center products is being actively weaponized in real-world attacks to drop cryptocurrency miners and ransomware payloads. In at least two of the Windows-related incidents observed by cybersecurity vendor Sophos, adversaries exploited the vulnerability to deliver Cerber ransomware and a  crypto miner  called z0miner on victim networks. The bug ( CVE-2022-26134 , CVSS score: 9.8), which was  patched  by Atlassian on June 3, 2022, enables an unauthenticated actor to inject malicious code that paves the way of remote code execution (RCE) on affected installations of the collaboration suite. All supported versions of Confluence Server and Data Center are affected. Other notable malware pushed as part of disparate instances of attack activity include Mirai and Kinsing bot variants, a rogue package called  pwnkit , and Cobalt Strike by way of a web shell deployed after gaining an initial foothold into the

Researchers Uncover 'Hermit' Android Spyware Used in Kazakhstan, Syria, and Italy
June 17, 2022Ravie Lakshmanan
An enterprise-grade surveillanceware dubbed Hermit has been put to use by entities operating from within Kazakhstan, Syria, and Italy over the years since 2019, new research has revealed. Lookout attributed the spy software, which is equipped to target both Android and iOS, to an Italian company named RCS Lab S.p.A and Tykelab Srl, a telecom services provider which it suspects to be a front company. The San Francisco-based cybersecurity firm said it detected the campaign aimed at Kazakhstan in April 2022. Hermit is modular and comes with myriad capabilities that allow it to "exploit a rooted device, record audio and make and redirect phone calls, as well as collect data such as call logs, contacts, photos, device location and SMS messages," Lookout researchers Justin Albrecht and Paul Shunk  said  in a new write-up. The spyware is believed to be distributed via SMS messages that trick users into installing what are seemingly innocuous apps from Samsung, Vivo, and Oppo, w

Chinese Hackers Exploited Sophos Firewall Zero-Day Flaw to Target South Asian Entity
June 17, 2022Ravie Lakshmanan
A sophisticated Chinese advanced persistent threat (APT) actor exploited a critical security vulnerability in Sophos' firewall product that came to light earlier this year to infiltrate an unnamed South Asian target as part of a highly-targeted attack. "The attacker implement[ed] an interesting web shell backdoor, create[d] a secondary form of persistence, and ultimately launch[ed] attacks against the customer's staff," Volexity  said  in a report. "These attacks aimed to further breach cloud-hosted web servers hosting the organization's public-facing websites." The zero-day flaw in question is tracked as  CVE-2022-1040  (CVSS score: 9.8), and concerns an authentication bypass vulnerability that can be weaponized to execute arbitrary code remotely. It affects Sophos Firewall versions 18.5 MR3 (18.5.3) and earlier. The cybersecurity firm, which issued a patch for the flaw on March 25, 2022, noted that it was abused to "target a small set of spec

BlackCat Ransomware Gang Targeting Unpatched Microsoft Exchange Servers
June 16, 2022Ravie Lakshmanan
Microsoft is warning that the BlackCat ransomware crew is leveraging exploits for  unpatched Exchange server  vulnerabilities to gain access to targeted networks. Upon gaining an entry point, the attackers swiftly moved to gather information about the compromised machines, followed by carrying out credential theft and lateral movement activities, before harvesting intellectual property and dropping the ransomware payload. The entire sequence of events played out over the course of two full weeks, the Microsoft 365 Defender Threat Intelligence Team  said  in a report published this week. "In another incident we observed, we found that a ransomware affiliate gained initial access to the environment via an internet-facing Remote Desktop server using compromised credentials to sign in," the researchers said, pointing out how "no two BlackCat 'lives' or deployments might look the same." BlackCat , also known by the names ALPHV and Noberus, is a relatively n

A Microsoft Office 365 Feature Could Help Ransomware Hackers Hold Cloud Files Hostage
June 16, 2022Ravie Lakshmanan
A "dangerous piece of functionality" has been discovered in Microsoft 365 suite that could be potentially abused by a malicious actor to mount attacks on cloud infrastructure and ransom files stored on SharePoint and OneDrive. The cloud ransomware attack makes it possible to launch file-encrypting malware to "encrypt files stored on SharePoint and OneDrive in a way that makes them unrecoverable without dedicated backups or a decryption key from the attacker," Proofpoint  said  in a report published today. The infection sequence can be carried out using a combination of Microsoft APIs, command-line interface (CLI) scripts, and PowerShell scripts, the enterprise security firm added. The attack, at its core, hinges on a Microsoft 365 feature called AutoSave that creates copies of older file versions as and when users make edits to a file stored on OneDrive or SharePoint Online. It commences with gaining unauthorized access to a target user's SharePoint Online

Unpatched Travis CI API Bug Exposes Thousands of Secret User Access Tokens
June 14, 2022Ravie Lakshmanan
An unpatched security issue in the Travis CI API has left tens of thousands of developers' user tokens exposed to potential attacks, effectively allowing threat actors to breach cloud infrastructures, make unauthorized code changes, and initiate supply chain attacks. "More than 770 million logs of free tier users are available, from which you can easily extract tokens, secrets, and other credentials associated with popular cloud service providers such as GitHub, AWS, and Docker Hub," researchers from cloud security firm Aqua  said  in a Monday report. Travis CI is a  continuous integration  service used to build and test software projects hosted on cloud repository platforms such as GitHub and Bitbucket. The issue, previously reported in 2015 and  2019 , is rooted in the fact that the  API  permits access to historical logs in cleartext format, enabling a malicious party to even "fetch the logs that were previously unavailable via the API." The logs go all

New Syslogk Linux Rootkit Lets Attackers Remotely Command It Using "Magic Packets"
June 14, 2022Ravie Lakshmanan
A new covert Linux kernel rootkit named  Syslogk  has been spotted under development in the wild and cloaking a malicious payload that can be remotely commandeered by an adversary using a  magic network traffic packet . "The Syslogk rootkit is heavily based on Adore-Ng but incorporates new functionalities making the user-mode application and the kernel rootkit hard to detect," Avast security researchers David Álvarez and Jan Neduchal  said  in a report published Monday. Adore-Ng, an  open-source rootkit  available since 2004, equips the attacker with full control over a compromised system. It also facilitates hiding processes as well as custom malicious artifacts, files, and even the kernel module, making it harder to detect. "The module starts by hooking itself into various file systems. It digs up the inode for the root filesystem, and replaces that inode's  readdir()  function pointer with one of its own," LWN.net  noted  at the time. "The Adore ver

June 14, 2022Ravie Lakshmanan
Cybersecurity researchers have detailed the workings of a fully-featured malware loader dubbed  PureCrypter  that's being purchased by cyber criminals to deliver remote access trojans (RATs) and information stealers. "The loader is a .NET executable obfuscated with SmartAssembly and makes use of compression, encryption, and obfuscation to evade antivirus software products," Zscaler's Romain Dumont  said  in a new report. Some of the malware families distributed using PureCrypter include  Agent Tesla ,  Arkei ,  AsyncRAT ,  AZORult ,  DarkCrystal RAT  (DCRat),  LokiBot ,  NanoCore ,  RedLine Stealer ,  Remcos ,  Snake Keylogger , and  Warzone RAT . Sold for a price of $59 by its developer named "PureCoder" for a one-month plan (and $249 for a one-off lifetime purchase) since at least March 2021, PureCrypter is advertised as the "only crypter in the market that uses offline and online delivery technique." Crypters act as the  first layer of de

Chinese 'Gallium' Hackers Using New PingPull Malware in Cyberespionage Attacks
June 13, 2022Ravie Lakshmanan
A Chinese advanced persistent threat (APT) known as Gallium has been observed using a previously undocumented remote access trojan in its espionage attacks targeting companies operating in Southeast Asia, Europe, and Africa. Called  PingPull , the "difficult-to-detect" backdoor is notable for its use of the Internet Control Message Protocol ( ICMP ) for command-and-control (C2) communications, according to new research published by Palo Alto Networks Unit 42 today. Gallium is notorious for its attacks primarily aimed at telecom companies dating as far back as 2012. Also tracked under the name  Soft Cell  by Cybereason, the state-sponsored actor has been  connected  to a broader set of attacks targeting five major telecom companies located in Southeast Asian countries since 2017. Over the past year, however, the group is said to have expanded its victimology footprint to include financial institutions and government entities located in Afghanistan, Australia, Belgium, Cam

HelloXD Ransomware Installing Backdoor on Targeted Windows and Linux Systems

HelloXD Ransomware Installing Backdoor on Targeted Windows and Linux Systems
June 13, 2022Ravie Lakshmanan
Windows and Linux systems are being targeted by a ransomware variant called HelloXD, with the infections also involving the deployment of a backdoor to facilitate persistent remote access to infected hosts. "Unlike other ransomware groups, this ransomware family doesn't have an active leak site; instead it prefers to direct the impacted victim to negotiations through  Tox chat  and onion-based messenger instances," Daniel Bunce and Doel Santos, security researchers from Palo Alto Networks Unit 42,  said  in a new write-up. HelloXD  surfaced in the wild on November 30, 2021, and is based off leaked code from Babuk, which was  published  on a Russian-language cybercrime forum in September 2021. The ransomware family is no exception to the norm in that the operators follow the tried-and-tested approach of  double extortion  to demand cryptocurrency payments by exfiltrating a victim's sensitive data in addition to encrypting it and threatening to publicize the inform

Iranian Hackers Spotted Using a new DNS Hijacking Malware in Recent Attacks

Iranian Hackers Spotted Using a new DNS Hijacking Malware in Recent Attacks
June 12, 2022Ravie Lakshmanan
The Iranian state-sponsored threat actor tracked under the moniker Lyceum has turned to using a new custom .NET-based backdoor in recent campaigns directed against the Middle East. "The new malware is a .NET based DNS Backdoor which is a customized version of the open source tool 'DIG.net,'" Zscaler ThreatLabz researchers Niraj Shivtarkar and Avinash Kumar  said  in a report published last week. "The malware leverages a DNS attack technique called 'DNS Hijacking' in which an attacker-controlled DNS server manipulates the response of DNS queries and resolves them as per their malicious requirements." DNS hijacking is a  redirection attack  in which DNS queries to genuine websites are intercepted to take an unsuspecting user to fraudulent pages under an adversary's control. Unlike  cache poisoning , DNS hijacking targets the DNS record of the website on the nameserver, rather than a resolver's cache. Lyceum , also known as Hexane, Spirli
