Microsoft Warns of Large-Scale Use of Phishing Kits to Send Millions of Emails Daily

Microsoft Warns of Large-Scale Use of Phishing Kits to Send Millions of Emails Daily

Mar 14, 2023 Threat Intelligence / Cyber Attack
An open source adversary-in-the-middle ( AiTM ) phishing kit has found a number of takers in the cybercrime world for its ability to orchestrate attacks at scale. The Microsoft Threat Intelligence team is tracking the threat actor behind the development of the kit under its emerging moniker  DEV-1101 . An  AiTM phishing attack  typically involves a threat actor attempting to steal and intercept a target's password and session cookies by deploying a proxy server between the user and the website. Such attacks are more effective owing to their ability to circumvent multi-factor authentication (MFA) protections, specifically time-based one-time passwords ( TOTPs ). DEV-1101, per the tech giant, is said to be the party behind several phishing kits that can be purchased or rented by other criminal actors, thereby reducing the effort and resources required to launch a phishing campaign. "The availability of such phishing kits for purchase by attackers is part of the industrial

Attackers Flood NPM Repository with Over 15,000 Spam Packages Containing Phishing Links

Feb 22, 2023 Open Source / Supply Chain Attack
In what's a continuing assault on the open source ecosystem,  over 15,000 spam packages  have flooded the npm repository in an attempt to distribute phishing links. "The packages were created using automated processes, with project descriptions and auto-generated names that closely resembled one another," Checkmarx researcher Yehuda Gelb  said  in a Tuesday report. "The attackers referred to retail websites using referral IDs, thus profiting from the referral rewards they earned." The modus operandi involves poisoning the registry with rogue packages that include links to phishing campaigns in their README.md files, evocative of a  similar campaign  the software supply chain security firm exposed in December 2022. The fake modules masqueraded as cheats and free resources, with some packages named as "free-tiktok-followers," "free-xbox-codes," and "instagram-followers-free." The ultimate goal of the operation is to entice user

U.S. Federal Agencies Fall Victim to Cyber Attack Utilizing Legitimate RMM Software

U.S. Federal Agencies Fall Victim to Cyber Attack Utilizing Legitimate RMM Software

Jan 26, 2023 Cyber Threat / Phishing
At least two federal agencies in the U.S. fell victim to a "widespread cyber campaign" that involved the use of legitimate remote monitoring and management (RMM) software to perpetuate a phishing scam. "Specifically, cyber criminal actors sent phishing emails that led to the download of legitimate RMM software – ScreenConnect (now ConnectWise Control) and AnyDesk – which the actors used in a refund scam to steal money from victim bank accounts," U.S. cybersecurity authorities  said . The joint advisory comes from the Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), and Multi-State Information Sharing and Analysis Center (MS-ISAC). The attacks, which took place in mid-June and mid-September 2022, have financial motivations, although threat actors could weaponize the unauthorized access for conducting a wide range of activities, including selling that access to other hacking crews. Usage of remote software by criminal grou

Hackers Bombard Open Source Repositories with Over 144,000 Malicious Packages

Dec 15, 2022
NuGet, PyPi, and npm ecosystems are the target of a new campaign that has resulted in over 144,000 packages being published by unknown threat actors. "The packages were part of a new attack vector, with attackers spamming the open source ecosystem with packages containing links to phishing campaigns," researchers from Checkmarx and Illustria  said  in a report published Wednesday. Of the  144,294 phishing-related packages  that were detected, 136,258 were published on NuGet, 7,824 on PyPi, and 212 on npm. The offending libraries have since been unlisted or taken down. Further analysis has revealed that the whole process was automated and that the packages were pushed over a short span of time, with a majority of the usernames following the convention "<a-z><1900-2022>." The fake packages themselves claimed to provide hacks, cheats, and free resources in an attempt to trick users into downloading them. The URLs to the rogue phishing pages were embed
Hackers Using SVG Files to Smuggle QBot Malware onto Windows Systems

Hackers Using SVG Files to Smuggle QBot Malware onto Windows Systems

Dec 15, 2022 Email Security / Endpoint Security
Phishing campaigns involving the  Qakbot malware  are using Scalable Vector Graphics ( SVG ) images embedded in HTML email attachments. The new distribution method was spotted by Cisco Talos, which  said  it identified fraudulent email messages featuring HTML attachments with encoded SVG images that incorporate  HTML script tags . HTML smuggling is a  technique  that relies on using legitimate features of HTML and JavaScript to run encoded malicious code contained within the lure attachment and assemble the payload on a victim's machine as opposed to making an HTTP request to fetch the malware from a remote server. In other words, the idea is to evade email gateways by storing a binary in the form of a JavaScript code that's decoded and downloaded when opened via a web browser. The attack chain spotted by the cybersecurity company concerns a JavaScript that's smuggled inside of the SVG image and executed when the unsuspecting email recipient launches the HTML attachme

Luna Moth Gang Invests in Call Centers to Target Businesses with Callback Phishing Campaigns

Luna Moth Gang Invests in Call Centers to Target Businesses with Callback Phishing Campaigns

Nov 22, 2022
The Luna Moth campaign has extorted hundreds of thousands of dollars from several victims in the legal and retail sectors. The attacks are notable for employing a technique called  callback phishing  or telephone-oriented attack delivery ( TOAD ), wherein the victims are social engineered into making a phone call through phishing emails containing invoices and subscription-themed lures. Palo Alto Networks Unit 42 said the attacks are the "product of a single highly organized campaign," adding, "this threat actor has significantly invested in call centers and infrastructure that's unique to each victim." The cybersecurity firm  described  the activity as a "pervasive multi-month campaign that is actively evolving." What's notable about callback phishing is that the email messages are completely devoid of any malicious attachment or booby-trapped link, allowing them to evade detection and slip past email protection solutions. These messages ty

Chinese Hackers Using 42,000 Imposter Domains in Massive Phishing Attack Campaign

Nov 17, 2022
A China-based financially motivated group is leveraging the trust associated with popular international brands to orchestrate a large-scale phishing campaign dating back as far as 2019. The threat actor, dubbed Fangxiao by Cyjax, is said to have registered over  42,000 imposter domains , with initial activity observed in 2017. "It targets businesses in multiple verticals including retail, banking, travel, and energy," researchers Emily Dennison and Alana Witten  said . "Promised financial or physical incentives are used to trick victims into further spreading the campaign via WhatsApp." Users clicking on a link sent through the messaging app are directed to an actor-controlled site, which, in turn, sends them to a landing domain impersonating a well-known brand, from where the victims are once again taken to sites distributing fraudulent apps and bogus rewards. These sites prompt the visitors to complete a survey to claim cash prizes, in exchange for which the
Warning: New Massive Malicious Campaigns Targeting Top Indian Banks' Customers

Warning: New Massive Malicious Campaigns Targeting Top Indian Banks' Customers

Nov 10, 2022
Cybersecurity researchers are warning of "massive phishing campaigns" that distribute five different malware targeting banking users in India. "The bank customers targeted include account subscribers of seven banks, including some of the most well-known banks located in the country and potentially affecting millions of customers," Trend Micro  said  in a report published this week. Some of the targeted banks include Axis Bank, ICICI Bank, and the State Bank of India (SBI), among others. The infection chains all have a common entry point in that they rely on SMS messages containing a phishing link that urge potential victims to enter their personal details and credit card information to supposedly get a tax refund or gain credit card reward points. The smishing attacks, which deliver Elibomi, FakeReward, AxBanker, IcRAT, and IcSpy, are just the latest in a series of similar rewards-themed malware campaigns that have been documented by  Microsoft, Cyble , and  K
Several Cyber Attacks Observed Leveraging IPFS Decentralized Network

Several Cyber Attacks Observed Leveraging IPFS Decentralized Network

Nov 09, 2022
A number of phishing campaigns are leveraging the decentralized InterPlanetary Filesystem (IPFS) network to host malware, phishing kit infrastructure, and facilitate other attacks. "Multiple malware families are currently being hosted within IPFS and retrieved during the initial stages of malware attacks," Cisco Talos researcher Edmund Brumaghin said in an analysis shared with The Hacker News. The research mirrors similar findings from Trustwave SpiderLabs in July 2022, which  found  more than 3,000 emails containing IPFS phishing URLs as an attack vector, calling IPFS the new "hotbed" for hosting phishing sites. IPFS as a technology is both resilient to censorship and takedowns, making it a double-edged sword. Underlying it is a peer-to-peer (P2P) network which replicates content across all participating nodes so that even if a file is removed from one machine, requests for the resource can still be served via other systems. This also makes it ripe for abuse
Robin Banks Phishing Service for Cybercriminals Returns with Russian Server

Robin Banks Phishing Service for Cybercriminals Returns with Russian Server

Nov 07, 2022
A phishing-as-a-service (PhaaS) platform known as  Robin Banks  has relocated its attack infrastructure to DDoS-Guard, a Russian provider of bulletproof hosting services. The switch comes after "Cloudflare disassociated Robin Banks phishing infrastructure from its services, causing a multi-day disruption to operations," according to a  report  from cybersecurity company IronNet. Robin Banks was  first documented  in July 2022 when the platform's abilities to offer ready-made phishing kits to criminal actors were revealed, making it possible to steal the financial information of customers of popular banks and other online services. It was also found to prompt users to enter Google and Microsoft credentials on rogue landing pages, suggesting an attempt on part of the malware authors to monetize initial access to corporate networks for post-exploitation activities such as espionage and ransomware. In recent months, Cloudflare's decision to blocklist its infrastruct

BazarCall Call Back Phishing Attacks Constantly Evolving Its Social Engineering Tactics

Oct 11, 2022
The operators behind the BazaCall call back phishing method have continued to evolve with updated social engineering tactics to deploy malware on targeted networks. The scheme eventually acts as an entry point to conduct financial fraud or facilitate the delivery of next-stage payloads such as ransomware, cybersecurity company Trellix  said  in a report published last week. Primary targets of the latest attack waves include the U.S., Canada, China, India, Japan, Taiwan, the Philippines, and the U.K. BazaCall , also called BazarCall, first gained popularity in 2020 for its novel approach of distributing the BazarBackdoor (aka BazarLoader) malware by manipulating potential victims into calling a phone number specified in decoy email messages. These email baits aim to create a false sense of urgency, informing the recipients about renewal of a trial subscription for, say, an antivirus service. The messages also urge them to contact their support desk to cancel the plan, or risk gett
Hackers Can Use 'App Mode' in Chromium Browsers' for Stealth Phishing Attacks

Hackers Can Use 'App Mode' in Chromium Browsers' for Stealth Phishing Attacks

Oct 07, 2022
In what's a new phishing technique, it has been demonstrated that the Application Mode feature in Chromium-based web browsers can be abused to create "realistic desktop phishing applications." Application Mode is designed to offer native-like experiences in a manner that causes the website to be launched in a separate browser window, while also displaying the website's favicon and hiding the address bar. According to security researcher mr.d0x – who also devised the browser-in-the-browser ( BitB ) attack method earlier this year – a bad actor can leverage this behavior to resort to some HTML/CSS trickery and display a fake address bar on top of the window and fool users into giving up their credentials on rogue login forms. "Although this technique is meant more towards internal phishing, you can technically still use it in an external phishing scenario," mr.d0x  said . "You can deliver these fake applications independently as files." This is

New EvilProxy Phishing Service Allowing Cybercriminals to Bypass 2-Factor Security

New EvilProxy Phishing Service Allowing Cybercriminals to Bypass 2-Factor Security

Sep 06, 2022
A new phishing-as-a-service (PhaaS) toolkit dubbed EvilProxy is being advertised on the criminal underground as a means for threat actors to bypass two-factor authentication (2FA) protections employed against online services. "EvilProxy actors are using reverse proxy and cookie injection methods to bypass 2FA authentication – proxifying victim's session," Resecurity researchers  said  in a Monday write-up. The platform generates phishing links that are nothing but cloned pages designed to compromise user accounts associated with Apple iCloud, Facebook, GoDaddy, GitHub, Google, Dropbox, Instagram, Microsoft, NPM, PyPI, RubyGems, Twitter, Yahoo, and Yandex, among others. EvilProxy is similar to adversary-in-the-middle ( AiTM ) attacks in that users interact with a malicious proxy server that acts as a go-between for the target website, covertly harvesting the credentials and 2FA passcodes entered in the login pages. It's offered on a subscription basis per service
JuiceLedger Hackers Behind the Recent Phishing Attacks Against PyPI Users

JuiceLedger Hackers Behind the Recent Phishing Attacks Against PyPI Users

Sep 02, 2022
More details have emerged about the operators behind the  first-known phishing campaign  specifically aimed at the Python Package Index (PyPI), the official third-party software repository for the programming language. Connecting it to a threat actor tracked as  JuiceLedger , cybersecurity firm SentinelOne, along with Checkmarx, described the group as a relatively new entity that surfaced in early 2022. Initial "low-key" campaigns are said to have involved the use of rogue Python installer applications to deliver a .NET-based malware called JuiceStealer that's engineered to siphon passwords and other sensitive data from victims' web browsers. The attacks received a significant facelift last month when the JuiceLedger actors  targeted PyPi package contributors  in a phishing campaign, resulting in the compromise of three packages with malware. "The supply chain attack on PyPI package contributors appears to be an escalation of a campaign begun earlier in th
Twilio Breach Also Compromised Authy Two-Factor Accounts of Some Users

Twilio Breach Also Compromised Authy Two-Factor Accounts of Some Users

Aug 29, 2022
Twilio, which earlier this month became a  sophisticated phishing attack , disclosed last week that the threat actors also managed to gain access to the accounts of 93 individual users of its Authy two-factor authentication (2FA) service. The communication tools company  said  the unauthorized access made it possible for the adversary to register additional devices to those accounts. It has since identified and removed the illegitimately added devices from the impacted accounts. Authy, acquired by Twilio in February 2015, allows  safeguarding online accounts  with a second security layer to prevent account takeover attacks. It's estimated to have nearly 75 million users. Twilio further noted its investigation as of August 24, 2022, turned up 163 affected customers, up from 125 it reported on August 10, whose accounts it said were hacked for a limited period of time. Besides Twilio, the sprawling campaign, dubbed  0ktapus  by Group-IB, is believed to have struck 136 companies,
