NoName Hacking Group Targets Email[.]it

An Italian email service provider, Email[.]it, has experienced a data breach resulting in the exposure of data belonging to nearly 600,000 users. A hacker group called NN (No Name) Hacking Group claims to be responsible for the breach and that they have stolen 44 databases from Email[.]it's servers. The breached data is available for sale on the dark web for a price varying between 0.5 and 3 bitcoin ($3,500 and $22,000).

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

NN Hacking Group alleges to be an international hacking group with operatives from countries across the world. The group seeks payouts for hacking company servers. Initially they will try to get the company to pay a ransom to avoid public disclosure of stolen data. If a company refuses, they will then sell it on the dark web. No Name Hacking Group claims to have breached the Italian email provider, Email.it, two years ago. The breach timeline as detailed by the hackers is as follows:

January 01, 2018: NNHackingGroup compromised and dropped a backdoor in Email[.]it’s server and began to exfiltrate data from the company's servers.

February 1st, 2020: NNHackingGroup reached out to Email.it, disclosing the breach and requesting a ransom, but the company declined to respond.

February 18, 2020: Email.it quietly tried to patch their servers, but failed to prevent NNHackingGroup’s from retaining access. The company also refuted NNHackingGroup’s claims that passwords were saved in clear text.

Figure 1: NN Hacking Group’s official Web page.

April 05, 2020: NNHacking group published the stolen data, advertising their shaming website on Twitter where the data was made available for sale, for a price varying between 0.5 and 3 bitcoin ($3,500 and $22,000) depending on the data included.

Figure 2: NN Hacking Group’s Twitter handle, promoting the breached data available for sale and calling out the breached organization.

Figure 3: Screenshot of NN Hacking Group’s price chart for Email.it’s data.

The group was likely able to gather so much information because Email[.]it allegedly saved all passwords in cleartext, allowing the hackers to access the accounts of nearly 600k users. The hackers were able to steal about 44 databases containing the user and business information from 2007 to 2020. The exposed information included:

  • Usernames
  • Passwords (Plaintext)
  • Mobile numbers
  • Email addresses
  • Email content and attachments
  • Sent/Received SMS information
  • Sent/Received Fax information
  • Web application source code

Figure 6: NNHG-provided sample data exposing unencrypted emails and attachments.

Conclusion

NoName Hacking Group is the latest in a string of self-proclaimed hacking groups that seeks to name and shame victims. These groups generally breach their victims, gather sensitive data, and threaten to publicly release this info if the ransom is not paid. If the breached organization does not pay the ransom demand, they are named on a blog or website run by the hacking team, and the stolen information is posted for the world to see. This is done to increase the likelihood that a victim will pay. ZeroFOX recommends enacting the recommendations above to reduce risk of compromise due to a third-party breach.

Ransomware Victim Disclosures : Maze, NEFILIM compromise new victims

The Maze, NEFILIM, and EVILEAKS ransomware groups have been busy over the last week, compromising a laundry list of new victims. Victims include organizations across a variety of verticals, including banking and financial services, healthcare, and communications.

Recommendations

  • Consider enabling additional ZeroFOX dark web coverage to identify mentions or discussion of targeting of your brand on the dark web
  • If you are interested in further insight, reach out to [email protected] for assistance

Details

Maze group infects new organizations across a variety of verticals

Initially observed in May 2019, the Maze ransomware is known for notable, high-profile attacks. Maze is a particularly sophisticated strain of Windows ransomware that encrypts files and makes them inaccessible while adding a custom extension containing part of the ID of the victim. Actors are known to exfiltrate data from the network for further extortion. Maze spreads mainly using email spam and various exploit kits, notably Spelevo and Fallout. The Maze group utilizes a public website to name and shame victims who do not pay ransom demands.

On April 30, 2020, the Maze group posted a new disclosure, claiming to have infected Banco BCR Bank. Banco BCR is a state-owned commercial bank that operates in Costa Rica. It is one of the largest banks in both Costa Rica and Central America. The hackers claim to have initially gained access to Banco BCR's network in August 2019. After the bank failed to secure the network, the hackers once again gained access to the bank's network in February 2020. They claim 11 million credit card credentials were stolen. Of these credit cards, 4 million are stated to be unique and 140,000 allegedly belong to people from the USA.

Other recent Maze targets include a domain owned by an American plastic surgeon ( kristintarbetmd[.]com), US-based chemical company PeroxyChem, global communications company ClearOne, regional ISP Dakota Carrier, American CPA Dakota & Morgan, and Colorado-based consulting company Homestead Management Corporation.

MAS Holdings targeted by NEFILIM

On April 27, 2020, sensitive data belonging to MAS Holdings, a major South Asian apparel manufacturer, was leaked by the operators of NEFILIM ransomware. MAS Holdings is one of South Asia’s largest apparel manufacturers, and has 53 manufacturing facilities in 17 countries, employing over 93,000 people globally. The hackers claim to have downloaded 300 gb of their private files from the breached organization’s network.

NEFILIM ransomware surfaced and began spreading at the end of February 2020. The ransomware encrypts files with AES-128 encryption and appends ".NEFILIM" to infected files. The malware shares code with the Nemty ransomware family but instead of using a Tor payment site, the malicious software relies on email communication for payment. The threat actor behind NEFILIM threatens to release stolen data if the ransom is not paid within seven days.

Brazlian National Supplementary Health Agency Shamed on EVILEAKS

On May 1, 2020, the threat actor, Razor, posted about 61GB of data belonging to Brazil’s National Supplementary Health Agency on EVILEAKS shaming website. Brazil’s National Supplementary Health Agency (ANS) was founded in 2000 by the ministry of health. The ANS monitors trends in private plan costs, providers, and inputs, authorizes corporate splits, mergers, acquisitions, transfer of shares, and articulates with consumer protection organizations. The ANS website (ans[.]gov[.]br) is currently down.

Conclusion

Ransomware operators continue to target organizations with the goal of extorting demands from victims in exchange for decrypting valuable data. Many ransomware operators have resorted to shaming their victims by leaking their information from the files stolen during the attack if the ransom is not paid. This tactic is likely an attempt to increase the likelihood that a compromised organization concedes to ransom demands.

Breach Disclosure: Tokopedia

Indonesia’s largest online store group, Tokopedia, has experienced a data breach resulting in exposure of data belonging to 91 million users. 15 million records are being offered for sale on hacking forum RaidForums. The remainder of the breached data is available for sale on a separate forum for a price of $5000. Breached records include name, password, email address and phone numbers of Tokopedia users.

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

On Friday, a hacker leaked 15 million records of Tokopedia users, on a public hacking forum.

Figure 1: Leak related to Tokopedia on a hacker forum

Later, the same actor was found selling the complete leaked Tokopedia database of 91 million users on a separate dark web forum for $5000.

The actor claims that the site was hacked in March 2020. Exposed information includes name, password, email address and phone numbers of Tokopedia users.

Breach Disclosure: Elanic

Major Indian fashion reseller Elanic has experienced a data breach involving over 2 million user records. This breach appears to date back to January 2020. These records contain email addresses of site users. Although Elanic has confirmed the breach, they have stated that they will not disclose the breach either publicly or privately to the affected users. It is unclear as to whether the company will take any remedial action.

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

Both Elanic and the data dump seller allege that the data is old, and was exposed via an insecure test server. The data dump was offered for sale on a public hacking forum. In total, 2.8 million email addresses, with being 2.3 unique addresses, were included in this dump.

Figure 1. Breach data dump offered for sale on a hacking forum

Breach Disclosure: TaiLieu

Vietnamese educational website, TaiLieu[.]vn, experienced a data breach resulting in the exposure of user data. It is currently unknown as to who is responsible for the breach. Nearly 7 million user records, including usernames and unsalted MD5 hashed passwords, have been exposed. This breach is available for sale on a popular hacker forum for a minimal price.

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

In November 2019, TaiLieu was breached and the leaked data was recently posted on a popular hacker forum. The incident resulted in the exposure of more than 7,000,000 records that contained the Personally Identifiable Information (PII) of TaiLieu[.]vn users, which is now available for sale on the dark web for an insignificant price of approximately 8 credits. This poster also included a screenshot of the breached data, which appears to be legitimate.

Figure 1: Screenshot of the leak advertised on a popular hacker forum.

The breached information included the following details:

  • User names
  • Email addresses
  • Dates of birth
  • Gender information
  • Passwords

The exposed passwords were stored as unsalted MD5 hashes. The MD5 hash algorithm is relatively trivial to reverse, and it is likely plain text passwords will be revealed.

US govt agencies to disable DoH until federal service is ready - BleepingComputer

The US Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) recommended disabling third-party encrypted DNS services until an official DNS resolution service with DNS over HTTPS (DoH) and DNS over TLS (DoT) support is ready. Until then, it reminded the government agencies to use the EINSTEIN 3 Accelerated (E3A) DNS server which comes with a sinkhole capability that blocks access to malicious infrastructure by overriding public DNS records identified as harmful, as the primary DNS resolver for any government workstations and communications. The support for DoH is enabled by default for Firefox users in the US, Chrome is currently experimenting with the feature, and Microsoft has announced plans to support DoH inside Windows in the upcoming future.

Surge in phishing attacks using legitimate reCAPTCHA walls

Security researchers at Barracuda Networks have discovered that cyber scammers are using the Google-owned legitimate reCAPTCHA walls to prevent automated URL analysis systems from accessing the actual content of phishing pages. According to the researcher, a single email credential phishing campaign had sent out more than 128,000 emails to various organizations and employees using reCAPTCHA walls to conceal fake Microsoft login pages. These phishing emails claim that the victim has received a voicemail message and once the victim solves the reCAPTCHA, they are redirected to the actual phishing page, which spoofs the Microsoft login page. When the victim enters the login information, it will be sent to the cyber scammers, who will likely use this information to hack into the real Microsoft account.

Spear-phishing campaign compromises executives at 150+ companies

Security researchers from Group-IB have uncovered a cybercrime group called “PerSwaysion” operating since mid-2019 and has breached the email accounts of high-ranking executives at more than 150 companies. The group relies on the spear-phishing technique wherein it sends the boobytrapped emails with a PDF file as an attachment to the victims. Once opened, it asks them to click on a link to view the actual content. The link redirects the victim to a Microsoft Sway (newsletter service) page, where a similar file asks the victim to click on another link. This last link redirects the victim to a page mimicking the Microsoft Outlook login page, where hackers collect the victim's credentials and send it to their C&C server. Finally, they generate new phishing PDF files with the current victim's full name, email address, and company legal name which will be sent to the new people who tend to be outside of the victim's organization and hold significant positions.

LockBit Is the New Ransomware for Hire

Security researchers warn of a fairly new ransomware strain called LockBit, prevalent in countries including the US, the UK, France, Germany, Ukraine, China, India, and Indonesia. LockBit is self-spreading and uses a dual method to map out and infect the victimized network. ARP tables, which map local IP addresses to device MAC addresses, helped to locate accessible systems, and server message block, a protocol used for sharing files and folders among networked machines, allowed the infected nodes to connect to uninfected ones. LockBit then executes a PowerShell script that spread the ransomware to those machines.

CursedChrome turns your browser into a hacker's proxy

To raise awareness of malicious Chrome extensions and the damage they can cause in enterprise environments, a security researcher published a proof-of-concept Chrome extension, named CursedChrome, that can turn Chrome browsers into proxy bots. This can allow hackers to navigate the web using an infected user's identity. CursedChrome consists of two different parts, a client-side component (the Chrome extension itself) and a server-side counterpart (a control panel where all CursedChrome bots report). After the extension has been installed on a few browsers, the attacker can log into the CursedChrome control panel and establish a connection to each infected host. Once the attacker has connected to an infected host, they can then navigate the web using the infected browser, and by doing so, hijack logged-in sessions and online identities to access forbidden areas, such as intranets or enterprise apps.

New VCrypt Ransomware locks files in password-protected 7ZIPs - BleepingComputer

New ransomware called VCrypt is targeting French victims by utilizing the legitimate 7zip command-line program to create password-protected archives of data folders. When executed, it extracts the legitimate 7zip command-line program called 7za.exe to the Temp folder as mod_01.exe. Then a series of commands execute to archive the files in the Windows folders in password-protected archives. The encrypted files use a naming format: username_foldername.vxcrypt. Each archive created by VCrypt will use the same hardcoded password when archiving files and then will delete the data in the folder. For other driver letters on the computer, the ransomware acts as a wiper. It also launches Internet Explorer to display a ransom note, written in French, stating details of retrieving the files. Since the ransom site is offline, the ransom amount is unknown.

New Kaiji Botnet Targets IoT, Linux Devices

The new Kaiji botnet is infecting the internet of things (IoT) devices and Linux-based servers and leveraging them in distributed denial-of-service (DDoS) attacks. The malware features various DDoS attack modules, an SSH brute-forcer module to continue its spread, and another SSH spreader that hijacks local SSH keys to infect known hosts which the server has connected to in the past. Once an SSH connection is established, a /usr/bin/lib directory is created and then Kaiji is installed under the filename ‘netstat’, ‘ps’, ‘ls’, or another system tool name. Once the malware is executed, it copies itself to /tmp/seeintlog and launches various malicious operations, including decrypting command-and-control (C2) addresses and registering the newly infected server to one of the command servers. Finally, the botnet fetches commands from the C2 server with instructions for specific DDoS attacks.

GitHub shuts down Popcorn Time repositories due to MPA DMCA notice - BleepingComputer

Due to a DMCA infringement notice, from the Motion Picture Association, GitHub was forced to take down two of its repositories used by the Popcorn Time developers for their Desktop client and API. Popcorn Time is a BitTorrent client with an integrated media player and the ability to browse through a list of copyrighted television shows and movies that can be streamed and watched directly in the client. While the Popcorn Time developers appear willing to push back against these DMCA notifications, GitHub likely will stay neutral and let courts decide if the infringement notifications should be enforced.

Phishing, Fraud, Fakes: Top 3 Digital Threats Targeting FinServ Today

With an increasing number of users relying on mobile banking through apps and online portals, financial institutions are getting more prone to risks of digital transformation. Financial services involve the exchange of money and sensitive information that if exposed or stolen could put both consumers as well as the integrity of the institution at risk. Public platforms like social media, websites, mobile apps, and support portals provide new vectors on which to host attacks, and, unsurprisingly, attackers are utilizing new methods for fraud and impersonation to take full advantage. A new report by ZeroFOX Alpha Team reveals the top three emerging and persistent digital attack tactics facing the financial services industry based on data from ZeroFOX’s own FinServ customer ecosystem over 12 months. Over the past few years, phishing attacks have spiked drastically, with a growing number of phishing kits developed and sold online. Banking mobile applications is another lucrative attack vector where attackers impersonate original apps to phish for banking credentials or exfiltrate sensitive information from the victim’s phone. Scammers also promote a variety of financial scams on social media, including money flipping and money muling that may lead to illegal money transfer. FinServ institutions, and their consumer bases, are frequently targeted with digital attacks due to the nature of the business and the handling of funds. As events like the Coronavirus pandemic have taken place, both the span of the attack surface and the frequency of attacks has increased.
