Trickbot Trojan Gets 'BokBot' Proxy Module to Steal Banking Info.




In 2017, IBM's X-Force team discovered a banking trojan named as 'BokBot', which redirects users to malicious online banking websites or can link victims to a browser procedure in order to insert unauthorized content onto official bank pages, it's also known as IcedID.

The authors of Trickbot trojan have begun to distribute a custom proxy module to the users; Trickbot trojan is a new component originated from BokBot's code for web injection, it works with some of the widely used web browsers.

The new variant came with its separate configuration file, it was detected on an infected system on 5th of July as "shadnewDll".

How does the malware work?

The malicious process begins with an infected Office Word document that downloads the Ursnif trojan after deploying a PowerShell script. Then, a Trickbot version along with the IcedID proxy module is received by the compromised host, it is programmed to intercept and modify web traffic.

After examining the component, Vitali Kremez, security researcher, said that it can be attached to the following web browsers: Microsoft Edge, Mozilla Firefox, Internet Explorer and Google Chrome.

Upon further inspection, the module appeared to be particularly adapted for TrickBot or other fraud bank operations which is based on the installion of this malware and its variants.

Referencing from the research of FireEye, "The TrickBot administrator group, which is suspected to be based in Eastern Europe, most likely provide the malware to a limited number of cyber criminal actors to use in operations." 

The Central Bank of Russia detected a new type of fraud during the transfer of funds through an ATM




According to the publication of the Center for monitoring and responding to computer attacks in the financial sphere of the General Directorate of protection and information security at Bank of Russia (FinCERT), the Central Bank reported a new type of fraud during the transfer of funds between cards through ATMs.
The document says, "previously expected  TRF-attacks (transaction reversal fraud) did not occur, but a new method of such an attack was recorded based on the imperfection of the scenarios for processing transfers from card to card using ATMs."
The fraud method is connected with the imperfection of the p2p-transfer scenario (transfer between individuals). In particular, when the transaction is cancelled, the fraudster has the opportunity to withdraw the transferred amount from another card and at the same time keep the money in his account.
The algorithm is quite simple. First, a transfer operation between individuals is selected and the card number of the beneficiary is indicated. The terminal sends two authorization messages to the beneficiary's Bank and to the sending Bank. After two approvals have arrived, the actual translation is performed.
However, the ATM then asks the sender for confirmation of the debit fee, but he does not agree, and a message about the return is sent to both Banks. As a result, the temporary holding of funds is removed from the sender's account, he saves all the money, but the beneficiary during this time withdraws the transfer from his card.
The Central Bank advises Banks to check the correctness of ATM scenarios. So, the approval for the cancellation of the operation to the sender should come only after the message about the successful return of the transferred funds from the beneficiary's Bank.
Another measure to combat this type of fraud is to obtain consent to charge a transfer fee before sending authorization messages for the operation.
The sender bank is responsible for the success of such attacks, said Alexei Golenishchev, the Director of e-business monitoring at Alfa-Bank.
In May, Ehackingnews described another type of fraud with Sberbank ATMs. The attacker did not insert a Bankcard into the machine, chose any operation and did not complete it. When the next customer came to the machine, he saw on the screen of ATM a proposal to insert the card and enter the pin code. When he did all, the operation of the attacker was automatically completed, after which the money was debited from the cardholder's account. Later, Sberbank said that Bank solved this problem and the attackers could not withdraw money anymore.

Criminals use new method to steal money from Sberbank customers



A new type of fraud using Sberbank ATMs appeared in Russia. Criminals use the imperfection of technology and inattention of citizens.

According to police, the attacker did not insert a Bankcard into the machine, chose any operation and did not complete it. When the next customer came to the machine, he saw on the screen of ATM a proposal to insert the card and enter the pin code. When he did all, the operation of the attacker was automatically completed, after which the money was debited from the cardholder's account.

First cases of such theft appeared six months ago. But in the last two weeks, the number of complaints from citizens to the police about this has increased rapidly. In all cases, the theft was committed when there was a queue at the ATM.

The the scheme worked only if the pin code was entered within one and a half minutes, otherwise, the terminal interrupted the operation. Police noted that attackers started using this scheme half a year ago but in the last two weeks the number of such incidents increased sharply.

Some experts believe that the problem is in the technology: normally, you must first to insert the card and then choose the operation. The second problem, according to experts, is a too long time-out. The basic time-out is 30 seconds. According to Yevgeny Tsarev, the RTM Group expert, a 90 seconds timeout is a serious vulnerability, and not technical, but social because an unprepared user can easily insert his card without looking at the monitor. Sberbank must reconfigure ATMs and reduce the time of the session, believes Mr. Tsarev.

An interesting fact is that on the channel "Russia 1" on the show with the participation of the head of Sberbank German Gref TV host said that customers of Sberbank are protected by graduates from the Faculty of Cybersecurity of leading Russian technical universities, while still being students. The youngest employee is about 20 years old.


Hackers stole money from Kukuruza(Kykyryza) cards using Apple Pay


83 Kykyryza(Kukuruza) cardholders suffered from the theft of funds. The fraudsters gained access to the logins and passwords from the mobile and Internet banking, and then they connected Apple Pay and withdrew funds. Now the problem is solved, the money is returned.

The Kykyryza card is a multifunctional bonus payment card, which is offered to its customers by the United Russian company Svyaznoy/Euroset. The card works in the Mastercard payment system.

Since May 2 complaints of Kykyryza cardholders about the theft of their funds began to appear on the website Banki.ru. Victims of the attack received SMS that their card is connected to Apple Pay, immediately after that, the money was withdrawn to the Tele2* number. All victims indicate that they did not receive SMS or Push-notifications with a verification code to connect to Apple Pay.

It turned out that hackers attacked a social service, where they received data about the owners of Kykyryza cards to log into the account and then they checked if the victims used the same username and password in the mobile or Internet Bank. If the data was the same, then the attackers connected mobile application Kykyryza to the Apple Pay and proceeded to withdraw money.

The company Svyaznoy/Euroset confirmed the theft of funds from Kykyryza card owners, noting that the number of victims is small, as only 20 million cards were issued. According to Alexander Malis, the SEO of the company, only 83 cardholders suffered.

“The hackers stole about 2 million rubles ($ 31 000),— said Mr. Malis.— The stolen funds were already returned to all the victims.”

Vladimir Dryukov, the Director of the Solar JSOC Cyber Attack Monitoring and Response Center, noted that the mobile application with this method of theft showed two serious vulnerabilities — the lack of protection from the change device when you log in to the mobile Bank and the lack of protection from the selection of the numbers.

However, according to Mr. Malis, Kykyryza card showed a high level of security in the conditions of a mass attack. He also clarified that a special update has already been released, which will not allow an unauthorized user to change the mobile device.

Can Aadhaar card data be misused to open bank accounts?

Can your Aadhaar Card data be misused by fraudsters to open bank accounts? Don’t worry! Aadhaar Card holders often ask what will happen if some fraudster tries to open a bank account against their names without their knowledge by obtaining a copy of their Aadhaar. People have raised apprehensions about whether they would be harmed or not. The Unique Identification Authority of India (UIDAI), the nodal authority for issuing Aadhaar, claims that Aadhaar Card data is completely safe and secured.

UIDAI has clearly stated that one can not open a bank account merely by presenting or submitting a physical Aadhaar Card or its photocopy. As per Prevention of Money-laundering (Maintenance of Records) Rules, 2005, and Reserve Bank of Indian circulars, a bank will go through a certain process of security checking. The process involves banks to perform verification through either biometric data or OTP authentication. Apart from this, there are another due diligence that need to be done by the bank before the Aadhaar Card can be accepted for banking transactions or KYC, says UIDAI. So as per the rules, no fraudster can open a bank account against your name using your Aadhaar Card details without verification through biometric or OTP.

However, if someone manages to open an account in a bank using your Aadhaar Card details without biometric or OTP authentication and other verification, then the bank will be held responsible for the loss, says UIDAI.

If you are still not sure about the security of your Aadhaar Card, then UIDAI provides another option for the verifiable 12-digit identification number. The Masked Aadhaar card is a viable option if you want to secure your Aadhaar Card details. While downloading Aadhaar Card details, you can opt for a more safer option of Masked Aadhaar card. This Masked Aadhaar Card only shows the last 4 digits of the 12-digit Aadhaar number. So, instead of carrying a phyiscal copy of your Aadhaar Card or a photocopy, it is advisable to have a Masked Aadhaar card, which in case of being misplaced or stolen is less likely to be misused. However, the Masked Aadhaar card does display other key details such as photograph, smart QR Code and demographic info.

SIM SWAP Fraud: A Mumbai Businessman Gets Robbed Off Of 1.86 Crore Via Missed Calls






A terrifying banking fraud, the researchers are calling “SIM SWAP”, recently preyed upon a Mumbai based businessman.
Reportedly, Rs.1.86 crore were harvested from this man’s bank balance via 6 late night missed calls.




Numerous other such cases of “SIM-SWAPPING” have also come to light in the metro cities of Bengaluru, Delhi, Bombay and Kolkata and the police cyber-cells are working on them.


This baffling fraud is not just subjective to people with lack of cyber knowledge or lack of critical thinking, technologically active people could also easily get drowned in the scam.


This seemingly stupid and unbelievable method of scamming people is fairly obvious to other parts of the cyber-world.


Despite being quite fresh in India, it has already affected a lot of people around the country and has targeted a fair number of “not-so-aware” mobile phone users, leaving their bank accounts pretty light.


When users switch from their old generation SIM cards to the upgraded versions, meaning when they change their 3G cards to 4G they use a technology called, “SIM SWAP” to register the new SIM card.


This technology had also come into play when the older SIM cards got switched by nano cards.




SIM SWAP:- WHAT? AND HOW?
SIM SWAP is a technique of replacing the existing SIM card by a duplicate one.

It can only be done when the attacker knows the unique 20 digit SIM number embarked on the SIM card.

Either the SIM-con would persuade the user into telling them the number or would hack into it on their own.




WHAT HAPPENED TO THE VICTIM!
Reportedly, the scammers had gotten the access to the victim’s 20 digit card number and had set the SIM SWAP process on, in the night time.

The scam broadly takes place in 2 steps, the SIM SWAP being the second step of the scamming technique.


Already privy to the banking ID and passwords, all that’s left for the fraudulent cons to find is the OTP on the registered mobile number and behold, the transactions begin!


Possibly, the victim was previously victimised by a phishing attack and unawares, mentioned his real password and account ID into a fake website fabricated by the cons.


The businessman had received 6 missed calls between the hours of 11pm and 2 am. These calls were initiated from 2 separate numbers, one beginning from +44(UK’s code).


The calls weren’t attended to as his phone was on the silent mode. Almost all the money got withdrawn from around 14 bank accounts the man had across the country, except for the 20 lakhs he somehow managed to recover.



When a user SIM SWAPS or basically EXCHANGES SIM CARD, all they do is register their phone number with their new SIM card.


This way the phone number is harvested and once that’s done the OTPs could be easily received, opening avenues of online shopping and ludicrous transactions in the owner’s name.


SIM SWAP could also affect people who communicate about their passwords or IDs via cell phones.


The technique depends upon who is a part of the communication. In actual and legitimate SIM exchanges, the users are connected to the servers of service providing organizations like Vodafone or Airtel.


These operators have ‘specifically designed official USSD codes’ for the SIM Swap process.


But when the swapping is not done by the user, the 20 digit SIM card number might fall into wrong hands.


If the wrongly swapped SIM card falls into the hands of the scammer, the victim would fall into immense danger.




HOW THE SCAM GOES ABOUT

The user would get call from the scammer, pretending to be from Idea or Jio. The caller would then, engage the user by saying that the call is for improving the call experience.


Once, set and familiar, the caller would guide the user’s way to SIM exchange, all the way wanting to extract the 20 digit SIM code.


The caller would try all means possible and would trick the user with any trickery possible to haul those 20 digits out.


After having persuaded the user about the 20 digits, the caller would ask them to press 1 or confirm the SIM swap.


The fraudster would then actually initiate the SWAP, having extracted the 20 digit SIM code, they were after.



Meaning, if supposedly the user has an Airtel SIM, the fraudster will too use an Airtel SIM to officially go through with the SIM swap.


Airtel would then send a confirmation text to the user’s cell number. Airtel would be sure that the SIM swap has actually happened and the attacker would have the cell number.


The actual user’s mobile will be left with no signals at all, whereas the fraudster will have full signals on the SIM and complete control over the cell number.


The fraudster would then incessantly call to make the user switch off the phone, in order to get a window to complete the fraud. Once that’s done, the user wouldn’t have any idea about it.



 
Aadhar number could also be an important credential that you would never want to share over the phone.

Also, always keep a close check on your bank account, and if any weird activity is speculated, immediately contact the bank and put a stop to the questionable transaction.
