Breach Disclosure: Zoosk

The online dating site, Zoosk, was involved in a breach dating back to January of 2020, which was identified later in May of 2020. This breach was carried out by the group named "ShinyHunters", who have been compromising and uploading breached companies data to popular hacking forums for free as of late. Around 24,000,000 accounts were included in this breach.

Recommendations

  • Enable 2-factor authentication for all of your organizational accounts to help mitigate phishing and credential stuffing attacks
  • If not already enabled, turn on the compromised credentials rule for all relevant entities and ensure relevant emails are entered for those entities, or reach out to [email protected] for assistance
  • If one of your entities receives an alert, ZeroFOX recommends immediate password changes for the affected account.

Details

The data in the breach contained gender, sexuality, date of birth, height, weight, religion, ethnicity, and political views. Some of the data involved in this breach could be damaging to users of the platform in terms of blackmail, as well as attempts to blackmail the individuals included in the breach.

Figure 1: Zoosk breach data listed by a RaidForums member

While ShinyHunters are the purported hackers responsible for the breach, and the ones who typically upload the breaches to RaidForums among other forums, this one was uploaded by the user "Gameranx" with contents identical to other ShinyHunters posts on RaidForums. In the comments section of this breach, ShinyHunters acknowledge the post and reference how Gameranx was faster than them in posting this to RaidForums.

It is our assessment that ShinyHunters posted this to another hacking forum, where Gameranx then downloaded the contents and uploaded it to RaidForums before ShinyHunters could post there.

FudSender: An Analysis of a Phishing Kit Targeting Facebook Users

ZeroFOX Alpha Team has obtained a phishing kit that is freely available on EvilLeaks Forum. The phishing kit has been available from 30th July 2020 and targets users of popular social media and social networking platform, Facebook.

Phishing is often used to steal user data by masquerading as a trustworthy entity. In this case, the phishing kit uses a fake login page identical to a legitimate Facebook login page to trick the victims. This phishing kit also offers crawler/bot detection to prevent automated tools from scanning the fake page.

Recommendations

  • Consider enabling multi-factor authentication for all accounts to prevent potential account takeover
  • Always verify the sender of suspicious or unexpected emails and messages
  • Never download attachments from unknown senders or suspicious emails
  • Consider enabling the compromised credentials rule for relevant entities. If needed, reach out to [email protected] for assistance

Details

Phishing is a low-cost, low barrier to entry form of cyber-attack that aims to obtain sensitive information or data by tricking a victim into believing that they are on a legitimate website. The phishing kit landing page spoofs the legitimate login page of Facebook and prompts the victim to enter credentials.

Figure 1 Figure 1: Landing page of fake phishing kit

Two scripts, login.php and access.php, are loaded upon entering the credentials. The function of the login.php script is to grab the username and password information entered by the victim.

Figure 2 Figure 2: login.php script, used to log victims’ usernames and passwords

The other script, access.php grabs the IP address of the victim and uses it to fetch details such as City, Region, Internet Service provider (ISP), User-Agent, Screen Resolution, etc., from the location intelligence provider site “ipapi[.]co”.

Figure 3 Figure 3: access.php script, used to log victim IP address and its related information

Both of the scripts login.php and access.php are configured in such a way to dump all the collected information from victims into a “logs.txt” file, every time a new victim enters their credentials.

Figure 4 Figure 4: Information dumped into “logs.txt” file

The phishing kit has an extra crawler and bot detection feature that uses "CrawlerDetect", a PHP class created by Mark Beech which can detect 1,000's bots/crawlers/spiders via the user agent and http_from header. "CrawlerDetect" has been used by several phishing kits, including prolific ones such as 16Shop, as well as free kits like this one. It is open-source and available in Mark Beech’s public GitHub repository.

Figure 5 Figure 5: CrawlerDetect used to detect bots/crawlers/spiders

The phishing kit also has two additional scripts badAgents.php and index.php to further prevent bots from accessing the fake web page. The script badAgents.php grabs the IP address from the incoming HTTP/HTTPS requests and fetches its organization details from the location intelligence site “ipapi[.]co”. The organization information, which is typically the owner of the ASN returned by ipapi, is then compared against the list of organization names of security providers.

Figure 6 Figure 6: badAgents.php script, to detect the organization name of phishing detection providers.

The second script index.php uses the hostname, user agent and IP address information already collected by access.php script and compares it against the list of hostnames, user agent and IP address of well-known phishing detection and URL scanner service providers. The phishing kit is designed in such a way that it responds with an “HTTP 404” error if it detects a bots/crawlers/spiders/web scanner.

Figure 7 Figure 7: index.php script, to detect hostnames, user agents, and IP addresses of phishing detection providers.

This kit is available for free on EvilLeaks forum, and their associated Telegram group has 5,242 followers with almost 1,100 views specifically of the Facebook phishing kit. The kit download page remains active at the time of this publication.

Figure 8 Figure 8: Telegram group of EvilLeaks, advertising Facebook kit.

The texts in the screenshot shared by the EvilLeaks group in their Telegram post led us to another website fudsender[.]com, which is the actual source of the phishing kit. FudSender is an illegal shopping site that sells Hacking tools, Malware, and Phishing kits.

Figure 9 Figure 9: FudSender Website Offering Facebook Phishing Kit.

The phishing kits offered by FudSender allow the attackers to spoof trusted brands increasing the chances of someone clicking on a fraudulent link.

Figure 10 Figure 10: Phishing Kits available for sale on FudSender that spoofs popular brands

The Crawler/Bot detection feature makes this phishing kit hard to detect with traditional security scanning technology. The availability of phishing kits makes it easy for cybercriminals, even those with minimal technical skills, to launch phishing campaigns. A phishing kit bundles phishing website resources and tools that need only be installed on a server. Once installed, all the attacker needs to do is send out emails to potential victims.

Conclusion

Phishing is a serious threat and hackers are deploying new tactics to steal information, for extortion, or even conventional fraud. The Facebook phishing kit is freely available and making it accessible to a wide range of would-be attackers, especially given that the group advertising this campaign has a considerable amount of followers. ZeroFOX recommends implementing the recommendations detailed above to reduce your risk of falling victim to these kinds of cyberattacks.

Firefox gets fix for evil cursor attack

Mozilla has fixed a bug in Firefox that was being abused in the wild by tech support scammers to create artificial mouse cursors and prevent users from easily leaving malicious sites. The bug tracked as CVE-2020-15654, is a classic "evil cursor" attack and works because modern browsers allow site owners to modify how the mouse cursor looks while users are navigating their websites. In evil cursor attacks, malicious websites tamper with cursor settings to modify where the actual cursor is visible on the screen, and where the actual click area is. Firefox 79.0 mitigates this issue.

Hackers abuse lookalike domains and favicons for credit card theft

Hackers are abusing a new technique that combines homoglyph domains with favicons to conduct credit card skimming attacks. Homograph attacks consist of abusing domains with homoglyphs: the characters that look the same to dupe users. Accroding to the resaerchers at Malwarebytes, a threat actor is using this technique on several domain names to load the popular Inter skimming kit inside of a favicon file. In one such instance, a .ico file was found to be associated with the cigarpaqe[.]com domain created by the attackers to mimic the real cigarpage.com. It turns out, the legitimate cigarpage.com website was hacked, and the attackers tactfully replaced its real website icon with the fake cigarpaqe[.]com's one. The illicit icon being loaded from the homoglyph domain has JavaScript appended to it. When this script loads along with the site's icon, sensitive information, including credit card numbers, can be exfiltrated to the attackers.

BEC Campaigns Target Financial Execs via Office 365

The attackers, dubbed Water Nue, have been targeting executives of more than 1,000 companies, most recently in the US and Canada through a series of business email compromise (BEC) campaigns. The ongoing BEC campaigns target office 365 accounts of business executives since March 2020 who they spear-phish to steal credentials to conduct further fraud. The phishing emails redirect victims to fake Office 365 login pages and thereby harvest credentials to send emails to the executives' subordinates containing invoices with altered banking info to steal funds via transfer requests. The attackers use basic phishing tools and do not involve backdoors or Trojans. They rely on public cloud services to obfuscate operations by hosting infrastructure in the services. & Fraud

CCleaner fixes bug that wipes Firefox extension settings - BleepingComputer

Piriform released CCleaner 5.70 to address a bug that was causing the app to wipe settings for Firefox extensions installed after upgrading to Firefox 79 when cleaning the web browser's Internet cache. This issue was caused by a change made by Mozilla in the way Firefox 79 stores extensions' data within the storage.sync area used to sync data to all devices signed in to the same Firefox Account. Once migrated, the extension data will be moved to be stored locally in a new storage-sync2.sqlite file saved in the user's profile folder. CCleaner does not recognize the two new companion files and deletes them, which causes your extension settings to be lost. CCleaner was notified of this bug and it released CCleaner v5.70.7909 on the same day to fix the issue for all Firefox 79 users.

Bugs in HDL Automation expose IoT devices to remote hijacking - BleepingComputer

Multiple vulnerabilities have been found by a security researcher in the HDL automation system that could have allowed the attackers to fully compromise the IoT devices. The researcher noticed that registering a new account on the mobile app of the HDL automation system, automatically generates another account for applying the settings, which allows defining a new password for the “debug” account while the one for the user remains the same. An attacker could register the email address for the “debug” username to receive the instructions for changing the password. Once the procedure completes, the attacker can control the components (lights, temperature, cameras, various sensors) in the HDL automated environment as well as configure them. The company has fixed the issues.

Fake security advisory used in clever cPanel phishing attack - BleepingComputer

Starting last Wednesday, cPanel and WebHost Manager (WHM) users began reporting a targeted phishing email campaign with an email subject of "cPanel Urgent Update Request" that was pretending to be a security advisory from the company, which states that updates had been released to fix "security concerns" in cPanel and WHM software versions 88.0.3+, 86.0.21+, and 78.0.49+ and recommends all users install the updates. cPanel is an administrative software installed on shared web hosting services. If the target of this phishing email falls for the scam and clicks on the 'Update your cPanel & WHM installations', they are redirected to a phishing website that prompts a user to log in with their cPanel credentials, with an intent to steal them. Targets of this scam are suggested to immediately log in to their web hosting provider and change the password on your account.

Cryptocurrency 'fraud' sues T-Mobile for letting him get hacked - New York Post

Reggie Middleton, the acting chief executive officer of a crypto company, Veritaseum, has accused the telecommunications provider, T-Mobile, for allegedly enabling the theft of $8.7 million worth of crypto in a series of SIM-swap attacks. In July 2017, the hackers allegedly targeted Middleton’s cryptocurrency account via his T-Mobile account. The accounts contained $8.7 million in cryptocurrency, which the hackers transferred to accounts owned and controlled by them. Middleton claimed that T-Mobile has repeatedly failed to prevent these SIM swaps and protect his information, while the company has continued to provide hackers with unauthorized access to Middleton’s account and personal information. He has sought a declaratory judgment in their favor, an award for damages, an award for costs and fees, prejudgment interest, and other relief as determined by the court. T-Mobile has declined to comment on the litigation.

Spying on satellite internet comms with a $300 listening station

Satellite internet communications are susceptible to eavesdropping and signal interception. Attackers could use a basic home-television gear to spy on the internet traffic for high-value targets, according to researchers from Oxford University. The researchers explained that an attacker could spy on specific satellites, whose locations are public, by pointing them with basic home-television consumer equipment, and could use software like EPS Pro to discover internet feeds. Once the attacker has identified a satellite internet connection he can record it and then parse it for valuable information. Attackers could also collect information even when the traffic is encrypted. The analysis of DNS could reveal the user’s Internet browsing history while the analysis of TLS certificates could allow fingerprinting the servers the user connected. The FBI is monitoring the potential for cyber threat actors to target maritime and aerospace critical infrastructure.

FBI says an Iranian hacking group is attacking F5 networking devices

A group of elite hackers associated with the Iranian government has been detected attacking the US private and government sector, according to a security alert sent by the FBI last week. The group is tracked as Fox Kitten, aka Parasite, provide an initial beachead to other Iranian hacking groups such as APT33 (Shamoon), Oilrig (APT34), or Chafer. They primarily operate by attacking high-end and expensive network equipment using exploits for recently disclosed vulnerabilities, before companies had enough time to patch devices. Due to the nature of the devices they attack, targets primarily include large private corporations and government networks. Once they gain access to a device, they install a web shell or backdoor, transforming the equipment into a gateway into the hacked network. Fox Kitten also upgraded its attack arsenal to include an exploit for CVE-2020-5902. FBI officials also warn that this group isn't targeting any particular sector, and any company running a BIG-IP device is likely to be targeted. US companies are asked to patch their on-premise BIG-IP devices to prevent successful intrusions and to deploy countermeasures and detection rules.

Google Chrome Browser Bug Exposes Billions of Users to Data Theft

Google’s Chromium-based browsers contain a security flaw that could allow attackers to bypass the Content Security Policy (CSP) on websites to steal data and execute rogue code. Tracked as CVE-2020-6519, the bug is found in Chrome, Opera and Edge, on Windows, Mac, and Android, potentially affecting billions of web users. Chrome versions 73 through 83 are affected. To exploit this vulnerability, an attacker first needs to gain access to the webserver to be able to modify the JavaScript code it uses. The attacker could then add a frame-src or child-src directive in the JavaScript to allow the injected code to load and execute it, bypassing the CSP enforcement and thus bypassing the site’s policy. Google has patched the issue and users are advised to update their browsers to the latest versions to avoid falling victim to an exploit.

Upgraded Agent Tesla malware steals passwords from browsers, VPNs

Agent Tesla remote access Trojan's new variants are upgraded with modules to steal credentials from applications, including popular web browsers, VPN software, as well as FTP and email clients. According to security researchers, the malware can extract credentials from the registry as well as related configuration or support files. Google Chrome, Chromium, Safari, Brave, FileZilla, Mozilla Firefox, Mozilla Thunderbird, OpenVPN, and Outlook are a few samples of the apps targeted by the latest Agent Tesla RAT variants. Once Agent Tesla harvests credentials and app config data, it will deliver it to its command-and-control (C2) server via FTP or STMP using credentials bundled within its internal configuration. Researchers also noted that the current variants will often drop or retrieve secondary executables to inject into, or they will attempt to inject into known (and vulnerable) binaries already present on targeted hosts.

Flaws in ‘Find My Mobile’ exposed Samsung phones to hack

A security researcher at Char49 has discovered multiple vulnerabilities in Samsung’s Find My Mobile that could have been chained to perform various malicious activities on Samsung Galaxy Phones. The Find My Mobile feature allows owners of Samsung devices to find their lost phones, it also allows them to remotely lock a device, block access to Samsung Pay, and completely wipe the content of the device. The four vulnerabilities found in Find My Mobile components could have been exploited by a rogue app installed on the device that requires access to the device’s SD card. The access allows the app to trigger the first vulnerability in the attack chain, then create a file used by the attacker to intercept communications with backend servers. The successful exploitation of the flaw would have allowed a malicious app to perform the same actions allowed by the Find My Mobile app, including force a factory reset, wipe data, locate the device, access to phone calls and messages, and lock and unlock the phone. The exploit chain works on unpatched Samsung Galaxy S7, S8, and S9+ devices. Samsung addressed them in October 2019.

Windows, IE11 zero-day vulnerabilities chained in targeted attack

An advanced threat actor exploited one of the two zero-day vulnerabilities that Microsoft patched on August 11, 2020, in a targeted attack earlier this year. The adversary chained two flaws in Windows, both unknown at the time of the attack, in an attempt to achieve remote code execution and increase their privileges on a compromised machine. The attack took place in May and targeted a South Korean company. Dubbed “Operation PowerFall,” the attack relied on a remote code execution (RCE) vulnerability in Internet Explorer 11, now tracked as CVE-2020-1380, and a flaw in Windows GDI Print/Print Spooler API allowing privilege escalation, now identified as CVE-2020-0986. After getting remote access to the target machine, the threat actor used a module that created a file named “ok.exe,” which leverages CVE-2020-0986 to run malicious code with elevated privileges. ZDI published an advisory on May 19, 2020, and the issue was exploited the very next day by the actors behind Operation PowerFall.

Dharma ransomware created a hacking toolkit to make cybercrime easy

The Dharma Ransomware-as-a-Service (RaaS) operation makes it easy for a wannabe cyber-criminal to get into the ransomware business by offering a toolkit that does almost everything for them. Known as Toolbelt, a PowerShell script when run, allows the attacker to download and execute a variety of tools from a mapped Remote Desktop shared folder, which indicates the toolkit is part of larger package distribution. The tool can execute 62 tasks and allows the affiliate to spread laterally through a network, harvest passwords, steal RDP passwords, and deploy the ransomware. It requires the affiliate's Remote Desktop share to be properly set up and accessible for the commands to be executed properly. For an inexperienced hacker, this toolkit contains all of the programs that the affiliate needs to steal passwords, spread to other machines on a network, and ultimately deploy the ransomware.

Re­VoL­TE attack can decrypt 4G (LTE) calls to eavesdrop on conversations

A team of academics has reported a vulnerability, named ReVoLTE, in the Voice over LTE (VoLTE) protocol that can be used to break the encryption on 4G voice calls. VoLTE is one of the protocols that handle voice communications on 4G networks. By default, the VoLTE standard supports encrypted calls. For each call, mobile operators must select an encryption key called a stream cipher to secure the call. Normally, the stream cipher should be unique for each call. Some mobile operators often use the same encryption key to secure multiple 4G voice calls that take place via the same base station (mobile cell tower). Attackers can leverage this to record a conversation between two 4G users using a vulnerable mobile tower and decrypt it. To achieve this the attacker has to place the call from the same vulnerable base station, in order to have its own call encrypted with the same/predictable encryption key. The GSMA has issued updates for the 4G protocol implementation to address and prevent ReVoLTE attacks.

RedCurl cybercrime group has hacked companies for three years

Security researchers have uncovered a new Russian-based hacking group that they claim has been focusing on the past three years on corporate espionage, targeting companies across the world to steal documents that contain commercial secrets and employee personal data. Cyber-security firm Group-IB has named them RedCurl and identified 26 RedCurl attacks, carried out against 14 organizations since 2018. The group relies on spear-phishing for initial access. The email content is carefully drafted, displaying the targeted company's address and logo, while the sender address features the company's domain name. The emails included links to malware-laced files that victims had to download. Once victims ran the content of the boobytrapped archives, they got infected with a collection of PowerShell-based trojans. The trojans allowed RedCurl operators access to basic operations, such as searching systems, downloading other malware, or uploading stolen files to remote servers. Victims were targeted across countries and industry sectors, including construction companies, retailers, travel agencies, insurance companies, banks, and law and consulting firms from countries like Russia, Ukraine, Canada, Germany, Norway, and the UK.
