Cyber Attacks/Data Breaches

TikTok hack: Over 2 billion records from user database stolen: security researchers claimed

Published

on

Cyber-security experts discovered Monday a possible data breach within TikTok’s Chinese short-form video app TikTok. This allegedly involved up to 2 million user records.

Many cyber-security experts tweeted about the “breach of an insecure Server that allowed TikTok to access its storage. They believe this contained personal user data.”

This is your forewarning. The #data #breach has been reported by # TikTok and there could be fallout in the next days. “We recommend that you change your TikTok password and enable Two-Factor authentication, if not already.” Tweeted BeeHive CyberSecurity.

“We have reviewed some of the data. We have already sent warning communications to our private clients and email subscribers,” it said.

Troy Hunt, the creator of data breaches information site wereibeenpwned posted a thread to Twitter to confirm if the sample data was genuine. He said that the evidence so far is “quite inconclusive”.

BlueHornet|AgaisntTheWest posted all the details on breached forums.

“Who would’ve thought @ TikTok would choose to store all of their internal backend code on one Alibaba Cloud instance with a sloppy password? They posted on Twitter about how easy it was to download the data.

According to reports, a TikTok spokesperson stated that their security team had “investigated the statement and concluded that the code in question was not related to TikTok’s backend source code.”

The Microsoft 365 Defender Research Team discovered a flaw in TikTok for Android. This vulnerability allows hackers to take over short-form, private videos of millions of users who click on a malicious link.

Microsoft discovered a serious vulnerability in TikTok Android’s TikTok application that could have allowed attackers access to user accounts via a single click.

The vulnerability would have required multiple issues to be linked together to exploit.

The tech giant stated that hackers could have used the vulnerability to hijack accounts without users’ knowledge if they clicked a link with a specially-crafted link.”

TikTok has denied recent claims that it was breached. Source code and user data were stolen. TikTok told that the data posted on a hacking forum is not related to the company.

A hacking group called ‘AgainstTheWest” created a topic in a hacking forum on Friday, claiming that they had breached TikTok as well as WeChat. One user shared screenshots from an alleged database that belonged to the companies. They claim it was accessed via an Alibaba cloud instance, and contained data for both TikTok users and WeChat users.

According to the threat actor, this server contains 2.05 billion records in a 790GB database that includes user data, platform statistics and software code. It also contains server information, cookies, auth tokens and server info.

Although the name AgainstTheWest might sound like a hacking group targeting Western countries, the threat actor claims that they only target countries or companies that are hostile to Western interests.

“Don’t be confused by the name, ATW targets countries that they perceive as a threat to west society. Currently they are targeting China, Russia, and have plans to target North Korea and Belarus in the future,” says CyberKnow, a cybersecurity researcher.

TikTok denies being hacked

CSNEST has been informed by TikTok that claims of hacking the company are false. The company also claimed that the source code posted on hacking forums was not part of its platform.

“This is an inaccurate claim. Our security team investigated the statement and found that the code in question was not related to TikTok’s backend code. WeChat data has never been merged with it.” – TikTok.

TikTok told us that they could not have leaked user data due to direct scraping of their platform. They also assured us that adequate security measures were in place to prevent automated scripts collecting user information.

 

Although WeChat is owned by Tencent, TikTok belongs to ByteDance. It is possible to see them in one database, which indicates that there was no breach of either platform.

The unprotected database was most likely created by a third party data broker or data scraper who extracted public data from both services, and then saved it to a single database.

These two companies are always under the scrutiny of privacy investigations by national service, so it is concerning to see such a rich cloud instance that contains both companies’ data.

Troy Hunt, creator of HaveIBeenPwned’s data breach notification service, stated in a thread that some data were valid. Hunt was unable to find any data that was not available publicly in TikTok. This proves an internal system breach.

 

Bob Diachenko, a “database hunter”, also confirmed the leaks as real but could not provide any concrete conclusions regarding the source of the data.

 

TikTok may have to take steps to stop the leakage of data even if further investigation reveals that it is legitimate. We asked for an additional comment on this front from TikTok, but have not received one.

As soon as new evidence becomes available, the story will be updated.

Cyber Attacks/Data Breaches

Founder of BreachForums, a cybercrime website, got 20 years of supervised release without prison time.

Published

The founder and operator of BreachForums, Conor Brian Fitzpatrick, received a sentence of time served and 20 years of supervised release for his involvement in running the cyber crime website.

Fitzpatrick, who used the online nickname “pompompurin,” was captured in March 2023 in New York and faced charges of conspiracy to commit access device fraud and possession of child pornography. He was later freed on a $300,000 bond, and in July 2023, he admitted to the charges.

BreachForums was a major online platform for trading stolen data since March 2022. Before it was shut down a year later, the website had over 340,000 members.

The website offered various types of stolen data, such as bank account information, Social Security numbers, personally identifying information (PII), hacking tools, breached databases, and account login information for hacked online accounts with service providers and merchants.

BreachForums also promoted services for accessing victim systems without authorization. The website affected millions of U.S. citizens and hundreds of U.S. and foreign companies, organizations, and government agencies.

Fitzpatrick also ran a “Leaks Market,” where he acted as a trusted intermediary (i.e., escrow) between users on the website who wanted to exchange hacked or stolen data, tools, and other illegal material.

“Fitzpatrick also allegedly operated an ‘Official’ databases section where BreachForums directly sold access to verified hacked databases through a “credits” system managed by the platform,” the U.S. Department of Justice stated.

Court records obtained by DataBreaches.net indicate that Fitzpatrick’s mental health may have influenced his sentence. Prosecutors suggested a 15-year prison term for the defendant a day before sentencing.

The 21-year-old is expected to spend the first two years of supervised release on house arrest with a GPS location tracker and receive mental health treatment. He has also been ordered to avoid using the internet for the first year and register with the state sex offender registration agency in any state where he lives.

The amount of restitution Fitzpatrick has to pay for victims’ losses has not been decided yet. Earlier this month, Fitzpatrick was imprisoned for breaking the terms of his pre-sentencing release by using an unmonitored computer and a virtual private network (VPN).

However, the illegal service did not stop after law enforcement seized the domains in March 2023. In June 2023, BreachForums was revived by the notorious ShinyHunters group, who were previously active on the Raid Forums, the takedown of which led to the launch of BreachForums.

Australia, U.K and U.S. have imposed financial penalties on a Russian Hacker for his role in the 2022 cyberattack on Medibank

A Russian citizen, Alexander Ermakov, who goes by various online aliases, has been sanctioned by the governments of Australia, the U.K., and the U.S. for his involvement in a major cyberattack on Medibank, an Australian health insurance provider, in 2022.

Ermakov is accused of hacking into the Medibank network and stealing and leaking the personal and medical data of about 9.7 million current and former customers of the company. The data breach was carried out by the REvil ransomware gang, which has since ceased operations.

The sanctions prohibit anyone from dealing with Ermakov’s assets, including cryptocurrency wallets or ransomware payments, and impose a travel ban on him. Anyone who violates the sanctions could face up to 10 years in prison.

The U.K. government said the sanctions are part of their efforts to combat the malicious cyber activities of Russia, which threaten the security and prosperity of the U.K. and its allies.

The U.S. Treasury Department also criticized Russia for harboring and supporting cyber criminals who launch ransomware attacks against the U.S. and other countries, targeting their businesses and critical infrastructure. The Treasury Department urged Russia to take action to stop cyber criminals from operating freely in its territory.

“Russian cyber actors continue to launch disruptive ransomware attacks against the United States and allied countries, targeting our businesses, including critical infrastructure, to steal sensitive data,” said Under Secretary of the Treasury Brian E. Nelson.

“This action demonstrates that the United States stands with our partners to disrupt ransomware actors who victimize the backbone of our economies and critical infrastructure,” the Treasury Department said.

Cyber Attacks/Data Breaches

Reddit hackers are threatening to release the stolen data from the February breach.

A cyberattack on Reddit in February, in which the threat actors claimed to have stolen 80GB of data from the company, was carried out by the BlackCat (ALPHV) ransomware gang.

Reddit revealed on February 9 that a phishing attack on an employee on February 5 resulted in the hacking of its systems.

The threat actors were able to access Reddit’s systems through a phishing attack, stealing internal documents, source code, employee data, and limited information about the company’s advertisers.

In a post, Reddit CTO Christopher Slowe, aka KeyserSosa, explained, “After successfully obtaining the credentials of a single employee, the attacker gained access to some internal documents, code, as well as some internal dashboards and business systems.”

“We don’t show any signs of a breach in our primary production systems,” which are the parts of our stack that run Reddit and store most of our data.

However, Reddit stated that neither user passwords nor credit card information nor production systems were compromised.

Reddit did not provide many details about the phishing attack, but they did say that it was similar to a Riot Games phishing attack that allowed hackers to gain access to systems and steal source code for League of Legends (LoL), Teamfight Tactics (TFT), and the Packman legacy anti-cheat platform of the company.

The threat actors demanded $10 million from Riot during the attack to prevent the leak of the stolen data. However, the threat actors attempted to sell the data on a hacking forum for $1 million if a ransom was not paid.


The ALPHV ransomware operation, more commonly referred to as BlackCat, now asserts that it was behind the February 5th cyberattack on Reddit. This information was first discovered by Dominic Alvieri and shared with BleepingComputer.

The threat actors claim to have stolen 80 GB of compressed data from the company during the attack and now plan to leak the data in a “Reddit Files” post on the gang’s data leak site.

The perpetrators of the threat claim that they attempted to get in touch with Reddit twice, on April 13 and June 16, and demanded $4.5 million in exchange for the deletion of the data.
“In my first email, I told them that I would wait for their IPO.” However, this seems like the ideal occasion! We are exceptionally sure that Reddit won’t pay any cash for their information,” compromised the ransomware activity.

“However, I am overjoyed to learn that the public will be able to read about all of the statistics they track about their users as well as all of the fascinating confidential data we collected. Did you know that they also censor users in secret? together with items from their GitHub!”

BleepingComputer has been able to confirm that this is the same attack that was disclosed by Reddit in February, despite the fact that Reddit declined to make any comments regarding BlackCat’s post.

Despite the fact that BlackCat is a group responsible for ransomware, they did not encrypt any devices during this attack.

A similar attack on Western Digital in March 2023, which resulted in a significant outage of the company’s My Cloud cloud service, is thought to have been carried out by the same hacking group.

The Western Digital attack’s perpetrators initially denied having a name, but screenshots of the stolen data were leaked on the ALPHV data leak website, where the perpetrators taunted the company about the attack.

In May, Western Digital sent notifications about data breaches to customers of its online stores, advising them that their data had been stolen during the attack.
