Dearcry Ransomware Impacting Microsoft Exchange Servers

 In Bitcoin News

Public repositories such as GitHub are notorious for being goldmines for cybercriminals, with some storing hundreds of thousands of leaked credentials, files, and – you guessed it – API keys. Then, around 80% of the victim’s account is used to initiate a big buy order for the same cryptocurrency. The low trading volume is what allows cybercriminals to massively inflate the price of the coin simply by initiating large buy orders. The Justice Department and Microsoft have not commented on the operation publicly beyond this statement.

Trading bots are popular with cryptocurrency traders since they provide automation, allowing trades to push through without having to be manually entered. Cybercriminals often take advantage of this by making their malware appear as trading bots and advertising them in online forums. Once the users download the fake trading bot, their device will be infected with coinminers or other malware designed to use up resources. In their search for more lucrative schemes, cybercriminals have started devising ways to take advantage of the sudden increase in value and relevance of cryptocurrency. Perhaps the most common method of monetization is the use of cryptocurrency-mining malware, which has emerged as an alternative to ransomware. Simply write out your private key and you will be able to recover your wallet if you ever lose access to it. You can also print out a QR code for both your public and private key, which avoids storing data digitally, providing a high level of security. The new ransomware comes less than a day after a security researcher published proof-of-concept exploit code for the vulnerabilities to Microsoft-owned GitHub. The code was swiftly removed a short time later for violating the company’s policies. If successful, attackers would have full access to the victim’s cryptocurrency exchange account and/or wallet and be able to use those funds as if they were the user themselves.

In case the exchange engages in high-volume trade campaigns involving altcoins with a fishy reputation, treat the cryptocurrency exchange with caution. Furthermore, participation in ventures like Initial Coin Offerings may be a sign of a shady exchange. This adds a software to your smartphone which adds extra security to your account. Without two-factor authentication, a hacker only needs your username and password to empty your balance. Regulators should also give guidance to fintech companies on how to develop secure technologies and should also provide a checklist of the minimum requirements a trading platform must have prior massive deployment. In the long run, I think they should play a more active role in auditing the brokerages, like regulatory compliance, just like Payment Card Industry Data Security Standard . So yes, trading platforms are more secure now than they were two years ago. Once the biggest exchange in existence, the company was gutted overnight after a half a billion dollar digital heist. After this record-breaking theft, evidence was revealed that showed the people running the exchange had not been forthcoming when it came to past incursions. To avoid a similar issue, look at a site’s reputation in places like Reddit’s r/Bitcoin forum before you risk your money.

We’ve even partnered with various cyber-security and compliance firms in the blockchain space. Yet, the best security partnership we can build is with the Binance community itself. As cases of wash trading on cryptocurrency exchanges rise, it is important to acknowledge the lack of continuous monitoring of cryptocurrency transactions on exchanges that need to be fixed. Securities and Exchange Commission in its presentation that 95% of bitcoin trading volume globally is fake and/or non-economic in nature. In fact, the trade exchange malware largest crypto exchange from South Korea, Upbit, has also been under scrutiny for wash trading after its officials were indicted for fraud in late 2018. This article will examine why exchanges conduct wash trading and analyze the Coinbit wash trading fiasco in detail. With that in mind, for those who might argue that the FBI’s action creates an unacceptable risk of overreach, it would be prudent to get a reaction from the business community, and particularly from those whose servers were involved in the FBI action.

While the move will have helped keep many organisations secure, it has also raised questions about the direction of cybersecurity. “This vulnerability allows a threat actor to navigate to getting system-level access, so the ability to laterally move to other machines has also been made easy,” says Varonis’ Lock. On Friday, Phillip Misner, a security manager at Microsoft, warned that a previously unseen group has been hitting unpatched Exchange servers with ransomware that’s been dubbed DearCry, aka DoejoCrypt. Security researchers have been warning all organizations using on-premises Exchange that until they patch the four zero-day flaws, they remain at serious risk of attacks from nation-states, criminals or others. Clear, the airport security company, filed to go public, betting on a resurgence in air travel.

Both Celas LLC and JMT Trader modified the same cryptocurrency application, Q.T. Bitcoin Trader; Union Crypto Trader modified the Blackbird Bitcoin Arbitrage application. The payload for the Windows malware is a Windows Dynamic-Link-Library.UnionCryptoUpdater.exe does not immediately download the stage 2 malware but instead downloads it after a time specified by the C2 server. This delay could be implemented to prevent researchers from directly obtaining the stage 2 malware. While the CelasTradePro application is likely a modification of QT Bitcoin Trader, the legitimate QT Bitcoin Trader DMG for OSX does not contain the postinstall script nor the plist file which creates a LaunchDaemon. When ran, only QTBitcoinTrader will be installed, and no additional programs will be created, installed, or launched. This OSX program from the Celas LLC site is an Apple DMG Installer. The OSX program has very similar functionality to the Windows program and also previously had a valid digital signature from Comodo.

I hold a Master’s degree in Computer Science from IIIT-Hyderabad, India. During my free time, I like to explore wilderness and go on nature walks around Sydney. These web clips pointed to web versions of the fake apps, with interfaces similar to those seen in the iOS applications. A warning on the company’s actual website opens with an alert about fraudsters scamming users with a similar named site and asks its users to steer clear of such apps. The Lazarus APT group’s continuous attacks on the financial sector are not much of a surprise to anyone. Recent investigation shows how aggressive the group is and how its strategies may evolve in the future. We were able to confirm that some of older Fallchill malware variants used exactly the same RC4 key.

13691, which directed DHS to help develop Information Sharing and Analysis Organizations to gather and share information on cyber threats amongst private and public entities across industry sectors and regions. On November 16, 2018, DHS launched the Cybersecurity and Infrastructure Security Agency to further facilitate public-private cooperation and information sharing, including through the provision of real-time cyber threat indicators and identifiers. In addition to these government initiatives, for-profit vendors also offer services premised on the same principle of collective defense and information sharing. As a matter of general policy, the U.S. government “does not encourage paying a ransom to criminal actors” but “understands that . Companies that decide to make a ransom payment typically do so through a third-party cyber insurance provider or cybersecurity consultant, which then arranges for a Bitcoin payment to the attacker in exchange for a decryption key or tool. Malicious browser extensions and applications are often to blame for compromised accounts or wallets and related losses. When you install browser extensions or applications, these programs can gain full access to various aspects of your browser or device, potentially allowing unauthorized access to your online accounts , and possibly even personal wallets.

To deter possible threats from cybercriminals by way of scripted or computer-based attacks, we limit the number of failed concurrent login attempts permitted for any single user or from any specific device. Our websites and mobile trading applications include an integrated timeout feature. After a period of inactivity, you will automatically be logged out to ensure the safety of your account and personal information. Whenever you attempt to log in from a web browser on an unknown device, you will be asked to answer one of your enhanced security questions after successfully entering your username and password to further validate your identity. To aid in the prevention of unauthorized access, all customers are required to select a unique username and a strong password when you open your first account. Passwords are required to meet minimum strength requirements, including overall length and a mixture of letters, numbers and special characters. We utilize advanced hardware and software firewalls to prevent unauthorized parties from gaining access to our systems and your personal information. Even though no exposed API keys we found during our investigation had withdrawal rights enabled, more than 90% had granted trade permissions, which would let cybercriminals easily empty out the victims’ trading accounts. Similarly to ENV files, files stored in public code repositories can contain exposed authentication tokens.

You Can Trade, Inc. is an online educational, news and entertainment media publication service that seeks to provide to the public a marketplace of potentially actionable investment and trading content, ideas, demonstrations and informational tools. HTTP response code 300 indicates that the server has no task for the updater and the application terminates immediately. If the HTTP response is code 200, then the updater gets the data in the response, decodes it from base64 encoding and decrypts it using RC4 with the hardcoded static key “W29ab@ad%Df324V$Yd“. It calculates the MD5 of the decoded and decrypted data, which is compared to a value stored inside, to verify the integrity of the transferred file. After that, the payload is extracted and saved to a hardcoded file location “/var/zdiffsec“, sets executable permissions for all users and starts the app with another secret hardcoded command-line argument “bf6a0c760cc642“. Apparently the command-line argument is the way to prevent the detection of its malicious functionality via sandboxes or even reverse engineering. We have previously seen this technique adopted by Lazarus group in 2016 in attacks against banks. As of 2018, it is still using this in almost every attack we investigated. For macOS users, Celas LLC also provided a native version of its trading app.

This malware collects process lists, excluding “” and “System” processes and gets the exact OS version from the registry value at “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion”. It seems that such values only exist from Windows 10, so we assume that the author developed and tested it on Windows 10. When we started this research, any user could download the trading application from the Celas website. Checking the installation package downloaded from the website confirmed the presence of a very suspicious updater. Assume the threat actors have moved laterally within the network and downloaded additional malware. The Dorusio program is likely a copy of an open-source cryptocurrency wallet application and loads a legitimate-looking wallet program . Aside from the Dorusio logo and two new services, the wallet appears to be the same as the Kupay Wallet. This application seems to be a modification of the open-source cryptocurrency wallet Copay distributed by Atlanta-based company BitPay. A Malware Analysis Report is intended to provide organizations with more detailed malware analysis acquired via manual reverse engineering.

If the bad actors successfully enter the websites using the victim’s identity, they can perform fund withdrawals. This may be a more efficient way to generate profits than outright cryptocurrency mining. Furthermore, attackers could manipulate the cryptocurrency prices with large-volume buying and/or selling of stolen assets, resulting in additional profits. The cryptocurrency industry is no different, and as exchanges release apps to help clients trade remotely, bad actors have tried to get clients to download fraudulent versions instead.

The new malware operates under the guise of a client-side trading software called “JTM Trading Software” and appears to be operated by the infamous North Korean Lazarus APT Group. While some details have changed, the methods between the JMT Trader scheme looks very similar to the AppleJeus operating seen by Kaspersky. Both use legitimate cryptotrading applications that are promoted from professional sites and both have a secondary program which is the malware component.

  • Some of the fake trading apps we looked at had an interface with trading updates, wallets, fund and cryptocurrency deposit and withdrawal features that appeared to function just like their legitimate counterparts.
  • This scheme starts with a professionally designed web site where the attackers promote the JMT Trader program as shown below.
