Banking Trojan Gains Ability to Steal Facebook, Twitter and Gmail Accounts

Security specialists have found another, refined type of malware in light of the famous Zeus saving money Trojan that takes something beyond ledger subtle elements. 

Named Terdot, the managing an account Trojan has been around since mid-2016 and was at first intended to work as an intermediary to lead man-in-the-center (MitM) assaults, take perusing data, for example, put away charge card data and login qualifications and infusing HTML code into went to website pages. 

Notwithstanding, analysts at security firm Bitdefender have found that the managing an account Trojan has now been patched up with new undercover work abilities, for example, utilizing open-source devices for mocking SSL testaments so as to access online networking and email accounts and even post for the tainted client. 

Terdot managing an account trojan does this by utilizing an exceptionally modified man-in-the-center (MITM) intermediary that permits the malware to catch any movement on a contaminated PC. 

Other than this, the new variation of Terdot has even included programmed refresh abilities that permit the malware to download and execute documents as asked for by its administrator. 

As a rule, Terdot focused on managing an account sites of various Canadian establishments, for example, Imperial Bank, Banque Nationale, PCFinancial, Desjardins, BMO (Bank of Montreal) and Scotiabank among others.




This Trojan Can Steal Your Facebook, Twitter and Gmail accounts


However, according to the latest analysis, Terdot can target social media networks including Facebook, Twitter, Google Plus, and YouTube, and email service providers including Google's Gmail, Microsoft's live.com, and Yahoo Mail.


Interestingly, the malware avoids gathering data related to Russian largest social media platform VKontakte (vk.com), Bitdefender noted. This suggests Eastern European actors may be behind the new variant.


The banking Trojan is mostly being distributed through websites compromised with the SunDown Exploit Kit, but researchers also observed it arriving in a malicious email with a fake PDF icon button.


If clicked, it executes obfuscated JavaScript code that downloads and runs the malware file. In order to evade detection, the Trojan uses a complex chain of droppers, injections, and downloaders that allow the download of Terdot in pieces.

Once infected, the Trojan injects itself into the browser process to direct connections to its own Web proxy, read traffic and inject spyware. It can also steal authentication info by inspecting the victim's requests or injecting spyware Javascript code in the responses.


Terdot can also bypass restrictions imposed by TLS (Transport Layer Security) by generating its own Certificate Authority (CA) and generating certificates for every domain the victim visits.


Any data that victims send to a bank or social media account could then be intercepted and modified by Terdot in real-time, which could also allow it to spread itself by posting fake links to other social media accounts.

"Terdot is a complex malware, building upon the legacy of Zeus," Bitdefender concluded. "Its focus on harvesting credentials for other services such as social networks and email services could turn it into an extremely powerful cyber espionage tool that is extremely difficult to spot and clean."
Bitdefender has been tracking the new variant of Terdot banking Trojan ever since it resurfaced in October last year. For more details on the new threat, you can head on to a technical paper (PDF) published by the security firm.
