An ex-employee of a NY credit union destroys 21GB of data as retaliation

Former credit union worker Juliana Barile admitted to breaking into the company’s computer systems without permission and erasing over 21 terabytes of data as retaliation for being sacked.

Acting U.S. Attorney Jacquelyn M. Kasulis stated that Barile “removed mortgage loan applications and other sensitive material held on its file server” after secretly accessing the computer system of her former employer, a New York Credit Union.

Within 40 minutes, over 20,000 papers were deleted
Until May 19, 2021, when she was fired, the defendant allegedly worked remotely for the credit union as a part-time employee.

Barile’s credentials for remote access were left in place despite a request from a credit union staffer to the bank’s IT support company. On May 21, two days later, Barile checked in for about 40 minutes.

During that period, the defendant removed about 20,000 files and around 3,500 directories, totaling about 21.3 gigabytes of information from the bank’s shared drive.

Files pertaining to customers’ mortgage loan applications and the financial institution’s anti-ransomware defence programme were deleted.

Barile opened several private Word documents, including files holding the credit union’s board minutes, in addition to deleting papers containing consumer and business information.

They didn’t cancel my access so I erased p drift lol. Five days later, on May 26, she also revealed to a pal via text messages how she was able to obliterate thousands of documents on her former employer’s servers. I removed their shared network papers from the system.

The New York credit union had backups of some of the material that the defendant had erased, but after Barile’s unauthorised intrusion, it still cost more than $10,000 to restore the lost data.

The FBI Assistant Director-in-Charge Driscoll continued, “Ms. Barile may have felt she was getting even with her employer by destroying files, but she inflicted just as much harm to customers.”

“Her small-scale retaliation not only put the bank at great danger for security, but it also caused chaos for consumers whose mortgage payments depended on paperwork and permissions.

“An inner threat can cause just as much destruction as an outside criminal, if not more. Now, the bank and its clients must deal with the enormous headache of one employee’s selfish behaviour.

After discontinuing support for ransom payments, insurer AXA was attacked by ransomware.

After discontinuing support for ransom payments, insurer AXA was attacked by ransomware.

A ransomware cyber assault has targeted the Thai, Malaysian, Hong Kong, and Philippine branches of the world’s largest insurance company, AXA.

The Avaddon ransomware organisation claimed yesterday, as reported by BleepingComputer, that it had stolen 3 TB of private data from AXA’s Asian operations.

Additionally, AXA’s international websites were down yesterday for a while due to a Distributed Denial of Service (DDoS) attack, according to BleepingComputer.

The group claims that the compromised data collected by Avaddon includes copies of ID cards, bank account statements, claim forms, payment records, contracts, claim forms for customers that reveal their sexual health diagnosis, and more.

The group’s statement follows AXA’s revelation that it would no longer cover ransomware extortion payments when underwriting cyber-insurance plans in France.

Asian AXA offices are targeted by a ransomware organisation.
The ransomware organisation Avaddon took responsibility for the attack on AXA’s offices in Asia yesterday.

The group also asserted that there was a DDoS attack ongoing against AXA’s websites hosted in Thailand, Malaysia, Hong Kong, and the Philippines:

The Avaddon ransomware gang initially made the threat to launch DDoS assaults to take down victims’ websites or networks until they get in touch and start negotiating to pay the ransom in February 2021.

When ransomware gangs started deploying DDoS assaults against their victims as an extra point of leverage in October 2020, BleepingComputer became the first publication to report on this new development.

About a week after AXA announced that payment for ransomware extortion settlements would no longer be included in their cyber-insurance policies sold in France, Avaddon announced the attack on AXA’s infrastructure.

Avaddon started dumping part of the stolen data on their leak site yesterday, as seen by BleepingComputer, even if the exact date of the incident remains unknown.

Avaddon also threatened to expose AXA’s priceless records if the insurance firm didn’t get in touch with them and work with them within 10 days.

The gang asserts to have obtained 3 TB of AXA data, which includes:

client medical records (including those containing sexual health diagnosis)
customer claims payments to consumers’ bank accounts scanned records content only available to hospitals and physicians (private fraud investigations, agreements, denied reimbursements, contracts)
Identity cards, passports, and other forms of identification

AXA: Access to data by a Thai partner only, “No Evidence”
AXA responded when approached by BleepingComputer as follows:

A recent targeted ransomware assault on Asia Assistance affected its IT operations in Thailand, Malaysia, Hong Kong, and the Philippines.

As a result, someone was able to access some data handled by Inter Partners Assistance (IPA) in Thailand.

“At this time, there is no proof that any additional data was accessed in Thailand beyond IPA.”

“The incident is being investigated by a dedicated taskforce that includes outside forensic experts. Partners in business and regulators have been informed.”

According to an AXA spokesman, “AXA takes data privacy very seriously and will take the appropriate procedures to notify and help all corporate clients and people impacted” if IPA’s investigations reveal that sensitive data of any persons have been affected.

The incident’s timing is interesting in light of this week’s FBI and Australian Cyber Security Centre (ACSC) alerts on ongoing Avaddon ransomware assaults aimed at enterprises from a wide range of industries in the US and around the world.

Attackers who use ransomware on enterprises continue to expand and interrupt many operations while demanding extortionate ransom payments.

The DarkSide cyberterrorist organisation recently requested $5 million to reactivate the Colonial Pipeline infrastructure.

Additionally, just this week, BleepingComputer reported that a $20 million ransomware demand was made on Ireland’s Health Services.

After taking data, the Android spyware BRATA wipes your smartphone.

Published

After taking data, the Android spyware BRATA wipes your smartphone.

The most recent version of the Android malware known as BRATA now includes several new and dangerous features, such as GPS tracking, the ability to use numerous communication channels, and a tool that wipes all evidence of malicious activity from the device by performing a factory reset.

Kaspersky originally identified BRATA as an Android RAT (remote access tool) in 2019 that mostly targeted Brazilian users.

A Cleafy report from December 2021 highlighted the malware’s appearance in Europe, where it was observed to target customers of online banking services and steal their credentials with the help of con artists posing as bank customer support representatives.

Cleafy analysts kept an eye out for new features in BRATA, and in a new research released today, they show how the malware is still evolving.

versions with modifications for various audiences
The most recent iterations of the BRATA malware currently target e-banking users in China, Latin America, the UK, Poland, Italy, and Spain.

With various overlay sets, languages, and even different apps to target particular populations, each version focuses on a different bank.

In all versions, the developers employ comparable obfuscation strategies, such as enclosing the APK file in an encrypted JAR or DEX package.

The VirusTotal scan below shows how effectively this obfuscation avoids antivirus detections.

On that front, before moving on to the data exfiltration process, BRATA now actively looks for indicators of AV presence on the device and tries to erase the discovered security tools.

 

New capabilities
The keylogging functionality, which is a new feature in the most recent BRATA versions, was discovered by Cleafy researchers and adds to the existing screen capturing capabilities.

All new variations also include GPS monitoring, however analysts are unsure of its precise function.

The performing of factory resets, which the actors do in the following circumstances, is the scariest of the new malevolent features.

The fraudulent transaction has been successfully finished after the compromise (i.e. credentials have been exfiltrated).
It has been discovered by the programme that it operates in a virtual environment, perhaps for analysis.
The kill switch used by BRATA is a factory reset, which wipes the device and increases the risk of a victim experiencing an unexpected and permanent loss of data.

Finally, BRATA now supports HTTP and WebSockets and has provided new channels for data exchange with the C2 server.

 

A direct, low-latency route that is perfect for in-the-moment communication and live manual exploitation is provided by the choice of WebSockets for the actors.

Additionally, because WebSockets don’t need to send headers with each connection, less suspicious network traffic is generated, which reduces the likelihood of being discovered.

Basic safety precautions
BRATA is only one of several sneaky RATs and Android banking trojans that target users’ banking credentials that are out there.

Installing apps from the Google Play Store, avoiding APKs from dubious websites, and always scanning them with an AV programme before opening them are the best strategies to prevent being infected by Android malware.

Pay close attention to the permissions that are requested during installation and don’t allow those that don’t seem necessary for the app’s primary functions.

Finally, keep an eye on your battery life and network traffic levels to spot any sudden spikes that can be caused by malicious processes that are running in the background.

After discovering a credit card skimmer, Costco admits a data breach.

Customers who recently made purchases at one of Costco Wholesale Corporation’s stores have received notification letters informing them that their credit card information may have been stolen.

According to Fortune 500 rankings, the retail giant—also known as Costco Wholesale and Costco—is an American multinational that runs a sizable chain of membership-only retail locations. It is the fifth-largest retailer in the world and the tenth-largest firm in the US by total revenue.

It runs e-commerce websites with 737 warehouses across the world that cater to the Americas, Europe, and Asia, among other global regions.

planted skimmer in the Costco warehouse
During a regular check by Costco staff, a credit card skimming device was found in one of the company’s warehouses, leading to the discovery of the breach.

The business got rid of the gadget, let the authorities know, and is now assisting the police in their investigation.

In breach notification letters, Costco informed possibly impacted customers that they had recently visited a Costco facility where a payment card skimming device had been found.

“Our member records show that throughout the possible operational period of the device, you swiped your payment card to make a purchase at the impacted terminal.”

probable theft of customer financial information
Costco said that if those who placed the card theft device had been successful in accessing the data prior to the skimmer being discovered and taken out, then consumers affected by the incident may have had their payment information stolen.

The magnetic stripe of your credit card, which contains your name, card number, card expiration date, and CVV, may have been obtained by unauthorised individuals if they were able to remove information from the device before it was identified, according to Costco.

Customers were given advice by the retailer to check their bank and credit card statements for fraudulent payments and alert the appropriate financial institutions to any suspect activities.

The total number of customers who were impacted or the warehouse where the skimmer device was discovered were not disclosed in the data breach notification letters sent to affected consumers.

Although the business withheld details on the incident’s exact timing, Costco customers have been complaining about fraudulent charges on their credit cards at least since February.
