New FakeCall Malware Variant Hijacks Android Devices for Fraudulent Banking Calls

New FakeCall Malware Variant Hijacks Android Devices for Fraudulent Banking Calls

Nov 04, 2024 Mobile Security / Financial Fraud
Cybersecurity researchers have discovered a new version of a well-known Android malware family dubbed FakeCall that employs voice phishing (aka vishing) techniques to trick users into parting with their personal information. "FakeCall is an extremely sophisticated Vishing attack that leverages malware to take almost complete control of the mobile device, including the interception of incoming and outgoing calls," Zimperium researcher Fernando Ortega said in a report published last week. "Victims are tricked into calling fraudulent phone numbers controlled by the attacker and mimicking the normal user experience on the device." FakeCall, also tracked under the names FakeCalls and Letscall, has been the subject of multiple analyses by Kaspersky, Check Point , and ThreatFabric since its emergence in April 2022. Previous attack waves have primarily targeted mobile users in South Korea. The names of the malicious package names, i.e., dropper apps, bearing the ma

Massive Git Config Breach Exposes 15,000 Credentials; 10,000 Private Repos Cloned

Nov 01, 2024 Vulnerability / Cloud Security
Cybersecurity researchers have flagged a "massive" campaign that targets exposed Git configurations to siphon credentials, clone private repositories, and even extract cloud credentials from the source code. The activity, codenamed EMERALDWHALE , is estimated to have collected over 10,000 private repositories and stored in an Amazon S3 storage bucket belonging to a prior victim. The bucket, consisting of no less than 15,000 stolen credentials, has since been taken down by Amazon. "The stolen credentials belong to Cloud Service Providers (CSPs), Email providers, and other services," Sysdig said in a report. "Phishing and spam seem to be the primary goal of stealing the credentials." The multi-faceted criminal operation, while not sophisticated, has been found to leverage an arsenal of private tools to steal credentials as well as scrape Git config files, Laravel .env files, and raw web data. It has not been attributed to any known threat actor or grou

Enterprise Identity Threat Report 2024: Unveiling Hidden Threats to Corporate Identities

Oct 31, 2024Identity Security / Browser Security
In the modern, browser-centric workplace, the corporate identity acts as the frontline defense for organizations. Often referred to as "the new perimeter", the identity stands between safe data management and potential breaches. However, a new report reveals how enterprises are often unaware of how their identities are being used across various platforms. This leaves them vulnerable to data breaches, account takeovers, and credential theft. The "Enterprise Identity Threat Report 2024" ( download here ) is based on exclusive data available only to the LayerX Browser Security platform. This data derives from LayerX's unique visibility into every user action in the browser, across industries. It provides a detailed analysis of emerging risks and uncovered hidden threats.

New Phishing Kit Xiū gǒu Targets Users Across Five Countries With 2,000 Fake Sites

Nov 01, 2024 Threat Intelligence / Malware
Cybersecurity researchers have disclosed a new phishing kit that has been put to use in campaigns targeting Australia, Japan, Spain, the U.K., and the U.S. since at least September 2024. Netcraft said more than 2,000 phishing websites have been identified the kit, known as Xiū gǒu, with the offering used in attacks aimed at a variety of verticals, such as public sectors, postal, digital services, and banking services. "Threat actors using the kit to deploy phishing websites often rely on Cloudflare's anti-bot and hosting obfuscation capabilities to prevent detection," Netcraft said in a report published Thursday. Some aspects of the phishing kit were documented by security researchers Will Thomas (@ BushidoToken) and Fox_threatintel (@banthisguy9349) in September 2024. Phishing kits like Xiū gǒu pose a risk because they could lower the barrier of entry for less skilled hackers, potentially leading to an increase in malicious campaigns that could lead to theft of

CERT-UA Identifies Malicious RDP Files in Latest Attack on Ukrainian Entities

CERT-UA Identifies Malicious RDP Files in Latest Attack on Ukrainian Entities

Oct 26, 2024 Cyber Attack / Threat Intelligence
The Computer Emergency Response Team of Ukraine (CERT-UA) has detailed a new malicious email campaign targeting government agencies, enterprises, and military entities. "The messages exploit the appeal of integrating popular services like Amazon or Microsoft and implementing a zero-trust architecture," CERT-UA said . "These emails contain attachments in the form of Remote Desktop Protocol ('.rdp') configuration files." Once executed, the RDP files establish a connection with a remote server, enabling the threat actors to gain remote access to the compromised hosts, steal data, and plant additional malware for follow-on attacks. Infrastructure preparation for the activity is believed to have been underway since at least August 2024, with the agency stating that it's likely to spill out of Ukraine to target other countries. CERT-UA has attributed the campaign to a threat actor it tracks as UAC-0215. Amazon Web Services (AWS), in an advisory of its own

Why Phishing-Resistant MFA Is No Longer Optional: The Hidden Risks of Legacy MFA

Oct 24, 2024 Ransomware / Generative AI
Sometimes, it turns out that the answers we struggled so hard to find were sitting right in front of us for so long that we somehow overlooked them. When the Department of Homeland Security, through the Cybersecurity and Infrastructure Security Agency (CISA), in coordination with the FBI, issues a cybersecurity warning and prescribes specific action, it's a pretty good idea to at least read the joint advisory. In their advisory AA24-242A, DHS/CISA and the FBI told the entire cybercriminal-stopping world that to stop ransomware attacks, organizations needed to implement phishing-resistant MFA and ditch SMS-based OTP MFA.  The Best Advice I Never Followed  This year, we have experienced an astonishing surge in ransomware payments, with the average payment increasing by a staggering 500%. Per the "State of Ransomware 2024" report from cybersecurity leader Sophos, the average ransom has jumped by 5X reaching $2 million from $400,000 last year. Even more troubling, RISK &
New Grandoreiro Banking Malware Variants Emerge with Advanced Tactics to Evade Detection

New Grandoreiro Banking Malware Variants Emerge with Advanced Tactics to Evade Detection

Oct 23, 2024 Cybercrime / Banking Security
New variants of a banking malware called Grandoreiro have been found to adopt new tactics in an effort to bypass anti-fraud measures, indicating that the malicious software is continuing to be actively developed despite law enforcement efforts to crack down on the operation. "Only part of this gang was arrested: the remaining operators behind Grandoreiro continue attacking users all over the world, further developing new malware and establishing new infrastructure," Kaspersky said in an analysis published Tuesday. Some of the other freshly incorporated tricks include the use of a domain generation algorithm (DGA) for command-and-control (C2) communications, ciphertext stealing ( CTS ) encryption, and mouse tracking. Also observed are "lighter, local versions" that are specifically focused on targeting banking customers in Mexico. Grandoreiro , active since 2016, has consistently evolved over time, taking efforts to stay undetected, while also widening its geog
Gophish Framework Used in Phishing Campaigns to Deploy Remote Access Trojans

Gophish Framework Used in Phishing Campaigns to Deploy Remote Access Trojans

Oct 22, 2024 Malware / Email Security
Russian-speaking users have become the target of a new phishing campaign that leverages an open-source phishing toolkit called Gophish to deliver DarkCrystal RAT (aka DCRat) and a previously undocumented remote access trojan dubbed PowerRAT. "The campaign involves modular infection chains that are either Maldoc or HTML-based infections and require the victim's intervention to trigger the infection chain," Cisco Talos researcher Chetan Raghuprasad said in a Tuesday analysis. The targeting of Russian-speaking users is an assessment derived from the language used in the phishing emails, the lure content in the malicious documents, links masquerade as Yandex Disk ("disk-yandex[.]ru"), and HTML web pages disguised as VK, a social network predominantly used in the country. Gophish refers to an open-source phishing framework that allows organizations to test their phishing defenses by leveraging easy-to-use templates and launch email-based campaigns that can the
Bumblebee and Latrodectus Malware Return with Sophisticated Phishing Strategies

Bumblebee and Latrodectus Malware Return with Sophisticated Phishing Strategies

Oct 22, 2024 Malware / Threat Intelligence
Two malware families that suffered setbacks in the aftermath of a coordinated law enforcement operation called Endgame have resurfaced as part of new phishing campaigns. Bumblebee and Latrodectus , which are both malware loaders, are designed to steal personal data, along with downloading and executing additional payloads onto compromised hosts. Tracked under the names BlackWidow, IceNova, Lotus, or Unidentified 111, Latrodectus, is also considered to be a successor to IcedID owing to infrastructure overlaps between the two malware families. It has been used in campaigns associated with two initial access brokers (IABs) known as TA577 (aka Water Curupira) and TA578. In May 2024, a coalition of European countries said it dismantled over 100 servers linked to several malware strains such as IcedID (and, by extension, Latrodectus), SystemBC, PikaBot, SmokeLoader, Bumblebee, and TrickBot. "Although Latrodectus was not mentioned in the operation, it was also affected and its

Hackers Exploit Roundcube Webmail XSS Vulnerability to Steal Login Credentials

Oct 20, 2024 Vulnerability / Email Security
Unknown threat actors have been observed attempting to exploit a now-patched security flaw in the open-source Roundcube webmail software as part of a phishing attack designed to steal user credentials. Russian cybersecurity company Positive Technologies said it discovered last month an email that was sent to an unspecified governmental organization located in one of the Commonwealth of Independent States (CIS) countries. However, it bears noting that the message was originally sent in June 2024. "The email appeared to be a message without text, containing only an attached document," it said in an analysis published earlier this week. "However, the email client didn't show the attachment. The body of the email contained distinctive tags with the statement eval(atob(...)), which decode and execute JavaScript code." The attack chain, per Positive Technologies, is an attempt to exploit CVE-2024-37383 (CVSS score: 6.1), a stored cross-site scripting ( XSS ) v

U.S. and Allies Warn of Iranian Cyberattacks on Critical Infrastructure in Year-Long Campaign

Oct 18, 2024 Cyber Intelligence / Critical Infrastructure
Cybersecurity and intelligence agencies from Australia, Canada, and the U.S. have warned about a year-long campaign undertaken by Iranian cyber actors to infiltrate critical infrastructure organizations via brute-force attacks. "Since October 2023, Iranian actors have used brute force and password spraying to compromise user accounts and obtain access to organizations in the healthcare and public health (HPH), government, information technology, engineering, and energy sectors," the agencies said in a joint advisory. The attacks have targeted healthcare, government, information technology, engineering, and energy sectors, per the Australian Federal Police (AFP), the Australian Signals Directorate's Australian Cyber Security Centre (ACSC), the Communications Security Establishment Canada (CSE), the U.S. Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the National Security Agency (NSA).

Beware: Fake Google Meet Pages Deliver Infostealers in Ongoing ClickFix Campaign

Oct 18, 2024 Threat Intelligence / Phishing Attack
Threat actors are leveraging fake Google Meet web pages as part of an ongoing malware campaign dubbed ClickFix to deliver infostealers targeting Windows and macOS systems. "This tactic involves displaying fake error messages in web browsers to deceive users into copying and executing a given malicious PowerShell code, finally infecting their systems," French cybersecurity company Sekoia said in a report shared with The Hacker News. Variations of the ClickFix (aka ClearFake and OneDrive Pastejacking) campaign have been reported widely in recent months , with threat actors employing different lures to redirect users to bogus pages that aim to deploy malware by urging site visitors to run an encoded PowerShell code to address a supposed issue with displaying content in the web browser. These pages are known to masquerade as popular online services, including Facebook, Google Chrome, PDFSimpli, and reCAPTCHA, and now Google Meet as well as potentially Zoom - meet.googl

Russian RomCom Attacks Target Ukrainian Government with New SingleCamper RAT Variant

Oct 17, 2024 Threat Intelligence / Malware
The Russian threat actor known as RomCom has been linked to a new wave of cyber attacks aimed at Ukrainian government agencies and unknown Polish entities since at least late 2023. The intrusions are characterized by the use of a variant of the RomCom RAT dubbed SingleCamper (aka SnipBot or RomCom 5.0), said Cisco Talos, which is monitoring the activity cluster under the moniker UAT-5647. "This version is loaded directly from the registry into memory and uses a loopback address to communicate with its loader," security researchers Dmytro Korzhevin, Asheer Malhotra, Vanja Svajcer, and Vitor Ventura noted . RomCom, also tracked as Storm-0978, Tropical Scorpius, UAC-0180, UNC2596, and Void Rabisu, has engaged in multi-motivational operations such as ransomware, extortion, and targeted credential gathering since its emergence in 2022. It's been assessed that the operational tempo of their attacks has increased in recent months with an aim to set up long-term persisten

AI from the attacker's perspective: See how cybercriminals are leveraging AI and exploiting its vulnerabilities to compromise systems, users, and even other AI applications Cybercriminals and AI: The Reality vs. Hype "AI will not replace humans in the near future. But humans who know how to use AI are going to replace those humans who don't know how to use AI," says Etay Maor, Chief Security Strategist at Cato Networks and founding member of Cato CTRL . "Similarly, attackers are also turning to AI to augment their own capabilities." Yet, there is a lot more hype than reality around AI's role in cybercrime. Headlines often sensationalize AI threats, with terms like "Chaos-GPT" and "Black Hat AI Tools," even claiming they seek to destroy humanity. However, these articles are more fear-inducing than descriptive of serious threats. For instance, when explored in underground forums, several of these so-called "AI cyber tools" were found to be nothing
