Hackers are baiting their victims with stolen financial data in a clever phishing scheme. Over 400,000 data points, including identity numbers, names, phone numbers, and payment records, are used to persuade consumers to click on a malicious link. This link downloads a potent virus called BitRAT that can steal passwords, spy on users, and install crypto mining software. In order to spread the remote access trojan known as BitRAT, the new campaign utilized confidential data taken from a bank as bait in phishing emails convincing victims to download a suspicious Excel file. BitRAT is a well-known remote access trojan (RAT) sold on dark web markets and forums used by cybercriminals. Because it costs $20 for a lifetime membership, it attracts all sorts of hackers and promotes the propagation of harmful payloads. In addition, the fact that BitRAT can be utilized in a range of activities, including phishing attacks, trojanized software, and watering hole attacks, makes it much more difficult to block. Although the hacker group responsible for the campaign is currently unknown, it is believed that they used SQL injection flaws to compromise the IT network of a Colombian cooperative bank. This is a typical method used by hackers to trick a database into producing an error message so they may discover the layout of the database. The exposed information includes, among other things, ID numbers (national resident identity), phone numbers, email addresses, customer names, income information, payment history, and residences. There are no indications that the information has been posted on any forums. However, this does not mean that consumers should not worry. The threat actors could use the obtained data to carry out phishing attacks themselves. The exfiltrated bank data file also has a macro embedded that downloads a second-stage DLL payload programmed to fetch and run BitRAT on the infected host. According to Qualys researcher Akshat Pradhan, the infected file downloads BitRAT embedded payloads from GitHub to the %temp% directory via the WinHTTP library. The GitHub repository, established in the middle of November 2022, stores encoded BitRAT loader samples, which are later decoded and launched to finish the infection chains. It’s crucial for business owners to be aware of these types of threats. Businesses can take proactive measures to protect their systems and sensitive data. Training employees to recognize and avoid suspicious emails and links and ensuring all systems are kept up-to-date with the latest security patches are just a couple of ways business owners can reduce the risk of falling victim to cyber-attacks.
A recently discovered exploit in Log4j, an open-source logging library used by multiple services and applications across the internet, allows attackers to execute remote code on any vulnerable servers. If exploited successfully, attackers can upload and import malware onto compromised servers, rendering those servers, and any machines that may connect to them, infected. Nearly every network security system runs a daily log, a list of activities performed, of activities that occurred on said network. As you can imagine, this gives popular logging libraries, like Log4j, immense reach, leaving millions of machines and servers vulnerable to attack. In order to exploit the vulnerability, an attacker simply needs to save a specific string of characters in the log. Since logging systems save a wide variety of events, such as messages received and sent by users, this exploit is extremely easy to take advantage of and can be triggered in a variety in ways. Due to the variety of applications vulnerable to the exploit and the immense range of possible ways to deliver the attack means that firewall protection alone cannot adequately protect your machines or servers. However, there has been an update to the log4j library, aimed at mitigating the vulnerability, but it will take time to ensure all machines are properly updated to protect against this exploit.

The Microsoft Defender Advanced Threat Protection Research Team have released a warning to all Windows users informing them that a notorious malware has resurfaced and has begun to spread once again. This malware, named Astaroth (The Great Duke of Hell), steals user credentials without ever needing to install malicious software. What makes this malware so notorious is not just that it deploys keyloggers and monitors the clipboard, aiding in its ability to steal login credentials, instead it does all this without downloading any executable file onto the user’s machine. The attack begins when the user opens a link within a phishing email. The link, unbeknownst to the user, opens a shortcut file which launches a terminal command that downloads and runs JavaScript code. From there the JavaScript pulls and runs two DLL files which do the dirty work of keylogging the user’s information and uploading it to the remote attacker. It does this entire process without the user ever knowing it is going on, raising serious concerns for businesses and personal machines. To stop the Malware, Anti-Virus programs need closely monitor how WMIC command-line code, applying rules to such code when necessary. This includes regularly checking the age of the files being called and flagging or completely blocking newly created DLL files. However, Microsoft’s anti-virus, as well as other anti-virus programs, have been updated to watch for such occurrences. Nevertheless, it is crucial that you remain cautious when online. Malware like this, even though modern anti-virus has been updated to watch for these suspicious actions, is not full proof. You should never look at your anti-virus as being the first line of defense; that what you are! If you are worried that an email may be a phishing scam, the chances are that it is. Always verify with the sender before you click on any links or download any files, and you will ensure that your computer and data remains safe!

A new malware strain has begun to attack IoT devices, wiping their firmware and rendering them useless. As of the writing of the article the malware has been live for a day and has already claimed a confirmed 2,000 victims in about 3 hours. Reports state that, Silex, the name of this malware, will continue to grow in scale and destructive nature. How Does Silex Work Reports state that Silex operates by destroying an IoT’s devices storage, removing the devices network config, dropping firewall rules, and ultimately ending by halting the device’s ability to operate. It does this by logging into the system using know default login credentials. In terms of destructive capabilities, this strain of malware is extremely threatening. If infected by the malware, the only option is to reinstall the device’s firmware, an operation many users will find to difficult to do. Experts believe this malware will lead to infected users throwing their devices away, thinking they were malfunctioning, rather than suspecting malware to be the case. For now, Silex appears to only be targeting Unix-like systems with default login credentials, but the malware also has a Bash shell version as well, meaning it could also be used to target systems running Unix like operating systems. This could spell disaster for Linux servers that have unsecured Telnet ports and poor admin or user credentials. At the time, the malware uses Iranian hosting services to operate, which has already been blacklisted by URLhaus. However, it is still recommended that you make sure your passwords are up to date and are anything but the default.
Across the United States, hackers have been targeted cities through the use of ransomware. Ransomware is a malicious attack on a computer system which completely locks the user out of their computer until a “ransom” is paid (usually in bitcoins). For those who think paying the ransom will be the easiest option should be aware that there is no guarantee that, upon payment, a decryption key will be provided. What makes ransomware especially threatening is the timer that not only counts down how many days left the user has before all files are deleted but also increases the price of decryption each passing day. Ransomware attacks should not be news to residents of Maryland. A similar attack has plagued Baltimore’s city government for a while, and the price of recovery has skyrocketed to $18 million. As of today, Lake City, Florida, another US city infected with ransomware, has decided to pay the ransom in order to regain access to their technology network. Despite Lake City’s technology department successfully disconnecting all infecting computers within a matter of minutes the virus was able to snake its way through the entire government’s network, with the police and fire departments being the exception. Lack City, Florida government officials have agreed to pay a ransom of $500,000. Upon payment, Lake City was granted a recovery key after paying the ransom, something other cities should take note of. Baltimore and Lake City are not the only two cities to have been plagued with the attack. Other cities such as Lynn, Massachusetts, Cartersville and Jackson County, Georgia have also been faced with this serious cyber-attack. These attacks, while expensive to fix, are a wakeup call to local governments. Ransomware is often targeted and successful on outdated systems, something each of the cities listed had. In order to combat these issues, and ensure they do not happen again, regular maintenance, updates, and patches are not only necessary but required. These attacks not only cripple the state government, but they also hurt the general public.
