CStealer exfiltrates stolen Chrome credentials to MongoDB database

  • Security researchers at MalwareHunterTeam identified an info-stealing trojan, named CStealer, which primarily targets credentials stored in Google Chrome.
  • Analysis performed by security researcher James showed that the malware contains hardcoded MongoDB credentials and uses the MongoDB C Driver to connect to a remote MongoDB database. Stolen credentials are sent to the MongoDB database for later retrieval.
  • Bleeping Computer warned that other parties who analyse CStealer could gain access to stolen information by retrieving the hard-coded MongoDB credentials from the malware.

Ongoing Campaigns

Researchers discover new spyware apps

  • Zscaler researchers detected a number of new spyware apps that are most likely used for malicious purposes. The apps are capable of stealing contacts, spying on text messages, stealing photos, spying on browsing history and banking apps, stealing GPS locations, and more.
  • The majority of the apps are poorly designed and store stolen data on servers lacking security. In some cases, the stolen data is transferred over plain-text channels. Such poor security means any server compromise could leak every victim’s data into the wild.
  • One of the apps has a package named ‘Lookout,’ the name of a well-known security vendor, and was most likely used to trick a victim into trusting the app.

Steam login stealing scam promoted through comments on user profiles

  • A security researcher known as nullcookies identified a phishing scam that seeks to steal the login credentials of Steam users. Bleeping Computer identified the propagation of the scam through comments on Steam account profiles.
  • The comments direct users to a site which purports to deliver free skins for use on the game Counter-Strike: Global Offensive. Targets are then prompted to enter their Steam username and password. Entered information is then exfiltrated by the attacker.
  • Bleeping Computer noted that the site uses a fake running chat screen to convince victims of the site’s legitimacy. The chat messages, which appear to discuss current events, are randomly inserted from a JavaScript script.

Hacker Groups

TICK threat group launch cyber espionage campaign

  • Researchers at Trend Micro discovered a new campaign, dubbed Operation ENDTRADE, by the TICK group. TICK, who have been active since 2008, are an ‘organised and persistent’ group specialising in cyber espionage operations. This latest campaign, which began in February 2019, targeted Japanese organisations with subsidiaries in China. The group’s targets operate in the defence, aerospace, chemical, and satellite industries.
  • The group conducted their attack using legitimate email addresses stolen in January 2019 from a Japanese economic research company and a public relations agency. The stolen email addresses were used to contact targets with spear phishing messages. The emails contained malicious attachments which the target was prompted to open. 
  • The group tried to steal documents by using a variety of open source and custom tools. New tools used by the group can evade detection, add to obfuscation, and escalate administrative privileges. The researchers identified TICK utilising an updated version of the DATPER backdoor, new tools named down_new malware and Avenger malware, and a modified version of the Cobalt Strike backdoor dubbed Casper malware.
  • The researchers concluded that TICK has ‘the skills and resources needed to coordinate sophisticated attacks’. A full evaluation of the group’s activities, including malware analysis, is available via Trend Micro’s blog.

Over 100 million individuals impacted by TrueDialog data breach

  • On November 26th, 2019, vpn Mentor researchers discovered an unsecured Microsoft Azure database belonging to TrueDialog, a US communications firm that provides SMS texting solutions to companies. The database contained 604GB of data, including almost 1 billion entries of highly sensitive data related to the company, its client base and the clients’ customers. The database has since been closed.
  • Exposed information included millions of TrueDialog account login details, such as email addresses, usernames, cleartext passwords and base64 encoded passwords, as well as account user details, including full names, phone numbers, addresses, emails and more.
  • Additionally, tens of millions of SMS messages sent via TrueDialog were also exposed, containing sensitive data such as full names of recipients, TrueDialog account holders and users, the contents of the messages, email addresses, phone numbers of recipients and users, and more.



Details for 21 million MixCloud accounts advertised on the Dark Web

  • A data reseller, operating under the alias A_W_S, is attempting to sell data belonging to approximately 21 million Mixcloud users.
  • The music streaming site was informed of the breach by Motherboard. A company spokesperson stated that the vast majority of users had signed up via Facebook authentication and consequently had no default passwords.
  • The seller, who is asking for approximately $4000 worth of Bitcoins for the data, sent a sample of 1,000 accounts to Motherboard. The data, which contained usernames, email addresses, and hashed passwords, was confirmed as genuine.



New Zealand gun buyback scheme website suffers data breach

  • On December 2nd, 2019, the national firearms buyback scheme website was shut down after an individual notified the New Zealand police that it was exposing the private data of gun owners. Exposed information included names, addresses, dates of birth, firearms licence numbers and bank account details.
  • According to a gun lobby group, 15 individuals had managed to access the information before the website was shut down, whereas New Zealand’s deputy police commissioner Mike Clement stated that officers knew of only one individual who had accessed the information.
  • The data breach has been blamed on a ‘human error’ by German software provider SAP, in which a software update was initiated without authorisation from the police. An investigation into what information may have been accessed is ongoing.
