Binance KYC Data Leak — Crypto Exchange Sets $290,000 Bounty On Blackmailer

August 07, 2019Swati Khandelwal
Malta-based cryptocurrency exchange Binance has become a victim of a ransom demand from a scammer who claimed to have hacked the KYC (Know Your Customer) data of thousands of its customers. The unknown attacker threatened the world's largest cryptocurrency exchange by volume to release KYC information of 10,000 users if the company did not pay 300 Bitcoins—that's equivalent to almost $3.5 million at today's exchange value. Although the authenticity of the hack is not confirmed yet, several photos of individuals holding their identity cards, such as passports and voter IDs, have been circulating across different online channels. In response to the incident, Binance just released an official statement today confirming that "an unidentified individual has threatened and harassed us, demanding 300 BTC in exchange for withholding 10,000 photos that bear similarity to Binance KYC data." Binance said the company is still investigating the legitimacy of those

This Cryptomining Malware Launches Linux VMs On Windows and macOS

June 21, 2019Mohit Kumar
Cybersecurity researchers from at least two firms today unveiled details of a new strain of malware that targets Windows and macOS systems with a Linux-based cryptocurrency mining malware. It may sound strange, but it's true. Dubbed " LoudMiner " and also " Bird Miner, " the attack leverages command-line based virtualization software on targeted systems to silently boot an image of Tiny Core Linux OS that already contains a hacker-activated cryptocurrency mining software in it. Isn't it interesting to use emulation to run single-platform malware on cross-platforms? Spotted by researchers at ESET and Malwarebytes , attackers are distributing this malware bundled with pirated and cracked copies of VST (Virtual Studio Technology) software on the Internet and via Torrent network since August 2018. VST applications contain sounds, effects, synthesizers, and other advanced editing features that allow tech-centric audio professionals to create music.

Are you using Komodo's Agama Wallet to store your KMD and BTC cryptocurrencies? Were your funds also unauthorisedly transferred overnight to a new address? If yes, don't worry, it's probably safe, and if you are lucky, you will get your funds back. Here's what exactly happened… Komodo, a cryptocurrency project and developer of Agama wallet, adopted a surprisingly unique way to protect its customers' funds. The company hacked its customers and unauthorisedly transferred nearly 8 million KMD and 96 Bitcoins from their cryptocurrency wallets to a new address owned by the company. Why? To secure funds of its customers from hackers. This may sound weird, but it's true. Komodo recently learned about a malicious open source, third-party JavaScript library that the company was using in its Agama Wallet app. The library, named "electron-native-notify," two months ago received a update from its anonymous author who included a secret backdoo
Cryptocurrency Hacks Still Growing — What Does That Mean for the Industry?

Cryptocurrency Hacks Still Growing — What Does That Mean for the Industry?

May 14, 2019Wang Wei
Though once synonymous with underground networks and black hat hackers, bitcoin and other cryptocurrencies have gone mainstream over the past two years. In 2017, we saw the skyrocket of bitcoin to an all-time high of close to $20,000 followed by a significant decline the following year. But beyond the ups and downs in the market for the world's largest cryptocurrency is a much more sinister story revolving around cyber-attacks of the economy's newest asset class. In 2018, it estimated that as much as $1.7 billion worth of cryptocurrencies were swindled away from investors (likely more) through a variety of means. Whether accomplished through hacking, phishing, or other forms of scamming, it's clear that the crypto industry is facing a serious dilemma with security. For a technological movement based on decentralization and the advantages it offers for security, the number of breaches occurring is startling. Cryptocurrencies offer users a way to send money with

U.S. Charges 9 'SIM Swapping' Attackers For Stealing $2.5 Million

May 10, 2019Mohit Kumar
The U.S. Department of Justice today announced charges against nine individuals, 6 of which are members of a hacking group called "The Community" and other 3 are former employees of mobile phone providers who allegedly helped them steal roughly $2.5 million worth of the cryptocurrency using a method known as "SIM Swapping." According to the 15-count indictment unsealed today, five Americans and an Irishman related to The Community hacking group are charged with conspiracy to commit wire fraud, as well as wire fraud and aggravated identity theft. Another three Americans, who reportedly are the former employees of mobile phone providers, are charged in a criminal complaint with the wire fraud. SIM Swapping , or SIM Hijacking , is a type of identity theft that typically involves fraudulently porting of the same number to a new SIM card belonging to the attacker. In SIM swapping, attackers social engineer a victim's mobile phone provider by convincing it

Binance Hacked — Hackers Stole Over $40 Million Worth Of Bitcoin

May 08, 2019Mohit Kumar
Binance, one of the largest cryptocurrency exchanges in the world, confirmed today that the company lost nearly $41 million in Bitcoin in what appears to be its largest hack to date. In a statement, Binance's CEO Changpeng Zhao said the company discovered a "large scale security breach" earlier on May 7, as a result of which hackers were able to steal roughly 7000 bitcoins, which worth 40.6 million at the time of writing. News of the hack comes just hours after Zhao tweeted that Binance has "to perform some unscheduled server maintenance that will impact deposits and withdrawals for a couple of hours." According to the company, malicious attackers used a variety of attack techniques, including phishing and computer viruses, to carry out the intrusion and were able to breach a single BTC hot wallet (a cryptocurrency wallet that's connected to the Internet), which contained about 2% of the company's total BTC holdings, and withdraw stolen Bitcoins

Rapidly Growing Electrum Botnet Infects Over 152,000 Users; Steals $4.6 Million

April 30, 2019Mohit Kumar
An ongoing attack against Electrum Bitcoin wallets has just grown bigger and stronger with attackers now targeting the whole infrastructure of the exchange with a botnet of over 152,000 infected users, raising the amount of stolen users' funds to USD 4.6 million. Electrum has been facing cyber attacks since December last year when a team of cybercriminals exploited a weakness in the Electrum infrastructure to trick wallet users into downloading the malicious versions of the software. In brief, the attackers added some malicious servers to the Electrum peer network which were designed to purposely display an error to legitimate Electrum wallet apps, urging them to download a malicious wallet software update from an unofficial GitHub repository. The phishing attack eventually allowed attackers to steal wallet funds (almost 250 Bitcoins that equals to about $937,000 at the time) and take full control over the infected systems. To counter this, the developers behind Electrum

Hackers Steal $19 Million From Bithumb Cryptocurrency Exchange

March 30, 2019Wang Wei
Hackers yesterday stole nearly $19 million worth of cryptocurrency from Bithumb , the South Korea-based popular cryptocurrency exchange admitted today. According to Primitive Ventures' Dovey Wan, who first broke the information on social media, hackers managed to compromise a number of Bithumb's hot EOS and XRP wallets and transferred around 3 million EOS (~ $13 million) and 20 million XRP (~ $6 million) to his newly-created accounts. The hacker then distributedly transferred the stolen digital assets to his different accounts created on other cryptocurrency exchanges, including Huobi, HitBTC, WB, and EXmo, via ChangeNow, a non-custodial crypto swap platform does not require KYC/account. Bithumb has been hacked multiple times in the past. Last time the popular cryptocurrency exchange was hacked in June 2018, when hackers stole $31 million, and in July 2017, when hackers stole $1 million worth of EOS from many wallets belonging to its users. "And this is the se

Hackers Favorite CoinHive Cryptocurrency Mining Service Shutting Down

February 28, 2019Wang Wei
Coinhive, a notorious in-browser cryptocurrency mining service popular among cybercriminals, has announced that it will discontinue its services on March 8, 2019. Regular readers of The Hacker News already know how Coinhive's service helped cyber criminals earn hundreds of thousands of dollars by using computers of millions of people visiting hacked websites . For a brief recap: In recent years, cybercriminals leveraged every possible web vulnerability [in Drupal , WordPress , and others ] to hack thousands of websites and wireless routers , and then modified them to secretly inject Coinhive's JavaScript-based Monero (XMR) cryptocurrency mining script on web-pages to financially benefit themselves. Millions of online users who visited those hacked websites immediately had their computers' processing power hijacked, also known as cryptojacking , to mine cryptocurrency without users' knowledge, potentially generating profits for cybercriminals in the background.
Hackers Actively Exploiting Latest Drupal RCE Flaw Published Last Week

Hackers Actively Exploiting Latest Drupal RCE Flaw Published Last Week

February 26, 2019Swati Khandelwal
Cybercriminals have actively started exploiting an already patched security vulnerability in the wild to install cryptocurrency miners on vulnerable Drupal websites that have not yet applied patches and are still vulnerable. Last week, developers of the popular open-source content management system Drupal patched a critical remote code execution (RCE) vulnerability (CVE-2019-6340) in Drupal Core that could allow attackers to hack affected websites. Despite releasing no technical details of the security vulnerability, the proof-of-concept (PoC) exploit code for the vulnerability was made publicly available on the Internet just two days after the Drupal security team rolled out the patched version of its software. Now, security researchers at data center security vendor Imperva discovered a series of attacks—that began just a day after the exploit code went public—against its customers’ websites using an exploit that leverages the CVE-2019-6340 security flaw. The attacks or

First Android Clipboard Hijacking Crypto Malware Found On Google Play Store

February 11, 2019Swati Khandelwal
A security researcher has discovered yet another cryptocurrency-stealing malware on the official Google Play Store that was designed to secretly steal bitcoin and cryptocurrency from unwitting users. The malware, described as a " Clipper ," masqueraded as a legitimate cryptocurrency app and worked by replacing cryptocurrency wallet addresses copied into the Android clipboard with one belonging to attackers, ESET researcher Lukas Stefanko explained in a blog post . Since cryptocurrency wallet addresses are made up of long strings of characters for security reasons, users usually prefer copying and pasting the wallet addresses using the clipboard over typing them out. The newly discovered clipper malware, dubbed Android/Clipper.C by ESET, took advantage of this behavior to steal users cryptocurrency. To do this, attackers first tricked users into installing the malicious app that impersonated a legitimate cryptocurrency service called MetaMask , claiming to let users

Critical Zcash Bug Could Have Allowed 'Infinite Counterfeit' Cryptocurrency

February 06, 2019Swati Khandelwal
The developers behind the privacy-minded Zcash cryptocurrency have recently discovered and patched a highly dangerous vulnerability in the most secretive way that could have allowed an attacker to coin an infinite number of Zcash (ZEC). Yes, infinite… like a never-ending source of money. Launched in October 2016, Zcash is a privacy-oriented cryptocurrency that claims to be more anonymous than Bitcoin, as the sender, recipient, and value of transactions remain hidden. In a blog post published today, the Zerocoin Electric Coin Company—the startup behind Zcash—revealed that one of its employees, Ariel Gabizon, discovered the vulnerability in its code on 1st March 2018, the night prior to his talk at the Financial Cryptography conference almost a year ago. Gabizon contacted Sean Bowe, a Zcash Company's cryptographer, immediately after discovering the counterfeiting vulnerability, as dubbed by the team, and the team decided to keep the flaw secret in order to avoid the risk o

Cryptocurrency Firm Loses $145 Million After CEO Dies With Only Password

February 04, 2019Mohit Kumar
QuadrigaCX, the largest bitcoin exchange in Canada, has claimed to have lost CAD 190 million (nearly USD 145 million) worth of cryptocurrency after the exchange lost access to its cold (offline) storage wallets. Reason? Unfortunately, the only person with access to the company’s offline wallet, founder of the cryptocurrency exchange, is dead. Following the sudden death of Gerry Cotten , founder and chief executive officer QuadrigaCX, the Canadian exchange this week filed for legal protection from creditors in the Nova Scotia Supreme Court until it locates and secures access to the lost funds. In a sworn affidavit filed by Cotten's widow Jennifer Robertson and obtained by Coindesk , Robertson said QuadrigaCX owes its customers some CAD 260 million (USD 198 Million) in both cryptocurrencies, including Bitcoin, Bitcoin Cash, Litecoin, and Ethereum, as well as fiat money. However, Robertson said the cryptocurrency exchange only has smaller amount in a 'hot wallet' (U

First Hacker Convicted of 'SIM Swapping' Attack Gets 10 Years in Prison

February 04, 2019Swati Khandelwal
A 20-year-old college student who stole cryptocurrency worth more than $5 million by hijacking victims' phone numbers has pleaded guilty and accepted a sentence of 10 years in prison. Ortiz was arrested last year on charges of siphoning millions of dollars in cryptocurrency from around 40 victims using a method commonly known as " SIM swapping ," which typically involves fraudulently porting of the same number to a new SIM card belonging to the attacker. In SIM swapping, attackers social engineer a victim's mobile phone provider by making a phony call posing as their target and claiming that their SIM card has been lost and that they would like to request a SIM swap. The attackers attempt to convince the target's telecommunications company that they are the actual owner of the phone number they want to swap by providing required personal information on the target, like their SSNs and addresses, eventually tricking the telecoms to port the target's pho
New Mac Malware Targets Cookies to Steal From Cryptocurrency Wallets

New Mac Malware Targets Cookies to Steal From Cryptocurrency Wallets

February 01, 2019Mohit Kumar
Mac users need to beware of a newly discovered piece of malware that steals their web browser cookies and credentials in an attempt to withdraw funds from their cryptocurrency exchange accounts. Dubbed CookieMiner due to its capability of stealing cookies-related to cryptocurrency exchanges, the malware has specifically been designed to target Mac users and is believed to be based on DarthMiner, another Mac malware that was detected in December last year. Uncovered by Palo Alto Networks' Unit 42 security research team, CookieMiner also covertly installs coin mining software onto the infected Mac machines to secretly mine for additional cryptocurrency by consuming the targeted Mac's system resources. In the case of CookieMiner, the software is apparently geared toward mining "Koto," a lesser-known, privacy-oriented cryptocurrency which is mostly used in Japan. However, the most interesting capabilities of the new Mac malware is to steal: Both Google Chro
Ethereum Classic (ETC) Hit by Double-Spend Attack Worth $1.1 Million

Ethereum Classic (ETC) Hit by Double-Spend Attack Worth $1.1 Million

January 08, 2019Swati Khandelwal
Popular cryptocurrency exchange Coinbase has suspended all transactions of Ethereum Classic (ETC)—the original unforked version of the Ethereum network—on their trading platforms, other products and services after detecting a potential attack on the cryptocurrency network that let someone spend the same digital coins twice. Why is this attack concerning? The heist resulted in the loss of $1.1 million worth of the Ethereum Classic digital currency. The digital currency immediately fell in price after the news came out. Coinbase revealed Monday that it identified "a deep chain reorganization" of the Ethereum Classic blockchain (or 51 percent attack of the network), which means that someone controlling the majority of miners on the network (over 50%) had modified the transaction history. After reorganizing the Ethereum blockchain, the attackers were able to what's called "double spend" about 219,500 ETC by recovering previously spent coins from the rightfu
StatCounter Analytics Code Hijacked to Steal Bitcoins from Cryptocurrency Users

StatCounter Analytics Code Hijacked to Steal Bitcoins from Cryptocurrency Users

November 08, 2018Mohit Kumar
Late last week an unknown hacker or a group of hackers successfully targeted a cryptocurrency exchange with an aim to steal Bitcoins by compromising the web analytics service it was using. ESET malware researcher Matthieu Faou this weekend spotted malicious JavaScript code on up to 700,000 websites that were bundled with the traffic tracking code from the leading web analytics platform StatCounter . However, after analyzing the code, the researchers found that hackers managed to compromise StatCounter and successfully replaced its tracking script with malicious JavaScript code primarily designed to target customers of the Gate.io cryptocurrency exchange. Like Google Analytics, StatCounter is also an old, but popular real-time web analytics platform reportedly being used by more than two million websites and generates stats on over 10 billion page views per month. Here's How Hackers Tried to Steal Bitcoins from Crypto Exchange Though the malicious code was also inject
Hackers Infect Over 200,000 MikroTik Routers With Crypto Mining Malware

Hackers Infect Over 200,000 MikroTik Routers With Crypto Mining Malware

August 03, 2018Mohit Kumar
Security researchers have discovered at least three massive malware campaigns exploiting hundreds of thousands of unpatched MikroTik routers to secretly install cryptocurrency miners on computers connected to them. In all, the malware campaigns have compromised more than 210,000 routers from Latvian network hardware provider Mikrotik across the world, with the number still increasing as of writing. The hackers have been exploiting a known vulnerability in the Winbox component of MikroTik routers that was discovered in April this year and patched within a day of its discovery, which once again shows people's carelessness in applying security patches on time. The security flaw can potentially allow an attacker to gain unauthenticated, remote administrative access to any vulnerable MikroTik router. The first campaign, noticed by Trustwave researchers, began with targeting networking devices in Brazil, where a hacker or a group of hackers compromised more than 183,700 Mikro

SamSam Ransomware Attacks Extorted Nearly $6 Million

July 31, 2018Swati Khandelwal
Ransomware has become a multimillion-dollar black market business for cybercriminals, and SamSam being a great example. New research revealed that the SamSam ransomware had extorted nearly $6 million from its victims since December 2015, when the cyber gang behind the ransomware started distributing the malware in the wild. Researchers at Sophos have tracked Bitcoin addresses owned by the attackers mentioned on ransom notes of each SamSam version and found the attackers have received more than $5.9 million from just 233 victims, and their profits are still on the rise, netting around $300,000 per month. "In total, we have now identified 157 unique addresses which have received ransom payments as well as 89 addresses which have been used on ransom notes and sample files but, to date, have not received payments," the new report by Sophos reads. SamSam Ransomware Attacks > What makes SamSam stand out from other forms of ransomware is that SamSam is not distributed

July 30, 2018Swati Khandelwal
Again some bad news for cryptocurrency users. KICKICO, a blockchain-based initial coin offering (ICO) support platform, has fallen victim to a suspected cyber attack and lost more than 70 million KICK tokens (or KickCoins) worth an estimated $7.7 million. In a statement released on its Medium post on July 26, the company acknowledged the security breach, informing its customers that an unknown attacker managed to gain access to the account of the KICK smart contracts and the tokens of the KICKICO platform on last Thursday at around 9:04 (UTC). KICKICO admitted that the company had no clue about the security breach until and unless several of its customers fell victim and complained about losing KickCoin tokens worth $800,000 from their wallets overnight. However, after investigating, the company found that the total amount of stolen funds was 70,000,000 KickCoin, which, at the current exchange rate, is equivalent to $ 7.7 million. KICKICO reported that suspected attackers
