New Phishing Kit Leverages SMS, Voice Calls to Target Cryptocurrency Users

Image
A novel phishing kit has been observed impersonating the login pages of well-known cryptocurrency services as part of an attack cluster codenamed CryptoChameleon that's designed to primarily target mobile devices. "This kit enables attackers to build carbon copies of single sign-on (SSO) pages, then use a combination of email, SMS, and voice phishing to trick the target into sharing usernames, passwords, password reset URLs, and even photo IDs from hundreds of victims, mostly in the United States," Lookout  said  in a report. Targets of the phishing kit include employees of the Federal Communications Commission (FCC), Binance, Coinbase, and cryptocurrency users of various platforms like Binance, Coinbase, Gemini, Kraken, ShakePay, Caleb & Brown, and Trezor. More than 100 victims have been successfully phished to date. The phishing pages are designed such that the fake login screen is displayed only after the victim completes a CAPTCHA test using hCaptcha, thus prevent...

Red Cross-Themed Phishing Attacks Distributing DangerAds and AtlasAgent Backdoors

Image
A new threat actor known as  AtlasCross  has been observed leveraging Red Cross-themed phishing lures to deliver two previously undocumented backdoors named DangerAds and AtlasAgent. NSFOCUS Security Labs described the adversary as having a "high technical level and cautious attack attitude," adding that "the phishing attack activity captured this time is part of the attacker's targeted strike on specific targets and is its main means to achieve in-domain penetration." The attack chains start with a macro-laced Microsoft document that purports to be about a blood donation drive from the American Red Cross that, when launched, runs the malicious macro to set up persistence, exfiltrate system metadata to a remote server (data.vectorse[.]com) that's a sub-domain of a legitimate website belonging to a structural and engineering firm based in the U.S. It also extracts a file named KB4495667.pkg (codenamed DangerAds), which, subsequently acts as a loader to launch...

Alert: Phishing Campaigns Deliver New SideTwist Backdoor and Agent Tesla Variant

Image
The Iranian threat actor tracked as APT34 has been linked to a new phishing attack that leads to the deployment of a variant of a backdoor called  SideTwist . "APT34 has a high level of attack technology, can design different intrusion methods for different types of targets, and has supply chain attack capability," NSFOCUS Security Labs said in a report published last week. APT34, also known by the names Cobalt Gypsy, Hazel Sandstorm (formerly Europium), Helix Kitten, and OilRig, has a track record of targeting telecommunications, government, defense, oil and financial services verticals in the Middle East since at least 2014 via spear-phishing lures that culminate in the deployment of various backdoors. One of the key traits of the hacking outfit is its ability to create new and updated tools to minimize the odds of detection and gain a foothold on compromised hosts for extended periods of time. SideTwist was first documented as used by APT34 in April...

W3LL Store: How a Secret Phishing Syndicate Targets 8,000+ Microsoft 365 Accounts

Image
A previously undocumented "phishing empire" has been linked to cyber attacks aimed at compromising Microsoft 365 business email accounts over the past six years. "The threat actor created a hidden underground market, named W3LL Store, that served a closed community of at least 500 threat actors who could purchase a custom phishing kit called W3LL Panel, designed to bypass MFA, as well as 16 other fully customized tools for business email compromise (BEC) attacks," Group-IB said in a report shared with The Hacker News. The phishing infrastructure is estimated to have targeted more than 56,000 corporate Microsoft 365 accounts and compromised at least 8,000 of them, primarily in the U.S., the U.K., Australia, Germany, Canada, France, the Netherlands, Switzerland, and Italy between October 2022 and July 2023, netting its operators $500,000 in illicit profits. Some of the prominent sectors infiltrated using the phishing solution include manufacturing, IT, consulting, fin...

Okta Warns of Social Engineering Attacks Targeting Super Administrator Privileges

Image
Identity services provider Okta on Friday warned of social engineering attacks orchestrated by threat actors to obtain elevated administrator permissions. "In recent weeks, multiple U.S.-based Okta customers have reported a consistent pattern of social engineering attacks against IT service desk personnel, in which the caller's strategy was to convince service desk personnel to reset all multi-factor authentication (MFA) factors enrolled by highly privileged users," the company  said . The adversary then moved to abuse the highly privileged Okta Super Administrator accounts to impersonate users within the compromised organization. The campaign, per the company, took place between July 29 and August 19, 2023. Okta did not disclose the identity of the threat actor, but the tactics exhibit all the hallmarks of an activity cluster known as Muddled Libra, which is said to share some degree of overlap with Scattered Spider and Scatter Swine. Central to the attacks is a commerci...

New SuperBear Trojan Emerges in Targeted Phishing Attack on South Korean Activists

Image
A new phishing attack likely targeting civil society groups in South Korea has led to the discovery of a novel remote access trojan called  SuperBear . The intrusion singled out an unnamed activist, who was contacted in late August 2023 and received a malicious LNK file from an address impersonating a member of the organization, non-profit entity Interlabs said in a new report. The LNK file, upon execution, launches a PowerShell command to execute a Visual Basic script that, in turn, fetches the next-stage payloads from a legitimate but compromised WordPress website. This includes the Autoit3.exe binary ("solmir.pdb") and an AutoIt script ("solmir_1.pdb") that's launched using the former. The AutoIt script, for its part, performs process injection using a  process hollowing technique , in which malicious code is inserted into a process that's in a suspended state. In this case, an instance of Explorer.exe is spawned to inject a never-before-seen RAT referred...

New Telegram Bot "Telekopye" Powering Large-scale Phishing Scams from Russia

Image
  A new financially motivated operation is leveraging a malicious Telegram bot to help threat actors scam their victims. Dubbed  Telekopye , a portmanteau of Telegram and kopye (meaning "spear" in Russian), the toolkit functions as an automated means to create a phishing web page from a premade template and send the URL to potential victims, codenamed Mammoths by the criminals. "This toolkit is implemented as a Telegram bot that, when activated, provides several easy-to-navigate menus in the form of clickable buttons that can accommodate many scammers at once," ESET researcher Radek Jizba said in a report shared with The Hacker News. The exact origins of the threat actors, dubbed Neanderthals, are unclear, but evidence points to Russia as the country of origin of the toolkit's authors and users, owing to the use of Russian SMS templates and the fact that a majority of the targeted online marketplaces are popular in the country. Multiple versions of Telekopy...

Russian Hackers Use Zulip Chat App for Covert C&C in Diplomatic Phishing Attacks

Image
  An ongoing campaign targeting ministries of foreign affairs of NATO-aligned countries points to the involvement of Russian threat actors. The phishing attacks feature PDF documents with diplomatic lures, some of which are disguised as coming from Germany, to deliver a variant of a malware called Duke, which has been attributed to APT29 (aka BlueBravo, Cloaked Ursa, Cozy Bear, Iron Hemlock, Midnight Blizzard, and The Dukes). "The threat actor used Zulip – an open-source chat application – for command-and-control, to evade and hide its activities behind legitimate web traffic," Dutch cybersecurity company EclecticIQ said in an analysis last week. The infection sequence is as follows: The PDF attachment, named "Farewell to Ambassador of Germany," comes embedded with JavaScript code that initiates a multi-stage process to drop the malware. APT29's use of invitation themes has been previously reported by Lab52, which documented an attack that imperso...
