Threats
A notorious cryptojacking group, 'The 8220 Gang' is actively leveraging a six-year-old Oracle WebLogic loophole (CVE-2017-3506) to release cryptocurrency mining viruses.
Once this vulnerable point is exploited then any person can gain unauthenticated access to remote commands and it means that someone's sensitive data or even the whole system could get compromised.
To evade the detection from the Windows Antimalware Scan Interface, the gang has been using PowerShell and gets its payload as an obfuscated one. Further, they take advantage of the valid Linux tool "lwp-download" to write random files on compromised hosts that affect numerous services.
This group of individuals has changed their techniques and tools over time consequently posing as a major threat to organizations in contemporary society.
The CarnavalHeist campaign is a cyberattack that is highly sophisticated and makes use of Microsoft Word documents to steal user credentials. Victims are sent malicious Word documents through the attack which will force them to download a malicious HTML file as soon as they are opened.
This then exploits a vulnerability in Microsoft Office Equation Editor permitting execution of PowerShell script. Through this, the attackers can steal login credentials.
The campaign mainly targets the financial sector organizations. To avoid detection, attackers adopt social engineering and exploit techniques.
The report shows that the number of ransomware attacks has increased significantly as ransomware creation is at its peak. The pandemic-induced increase in remote work has contributed to this surge. Attacks have gone up by 148%.
Additionally, in 2023, the average demand for ransom rose to $1.54 million from $0.88 million in 2022.
Moreover, companies experience an average of 22 days of downtime after a ransomware attack while the ransomware attacks cost has risen by 13% over the past five years and it stands at an average price of $1.85 million per incident.
According to the report, there is an increasing danger of malicious npm packages that aim at developers. The malicious packages stole SSH keys from developer computers by uploading them to GitHub repositories.
They were taken down from npm in January, and an alarming rise of malicious packages on open-source package managers has been identified between 2020 and 2023, a considerable share of which is hosted using GitHub.
Packers are commonly utilized by hackers to bundle legitimate content with malicious code, these packers are also legitimate tools.
Among other things, the report shows that phishing campaigns often employ ZIP and SFX archives while UPX enables code extraction and encryption into memory for malware.
The significance of recognizing which packer has been employed within packed malware and extracting the contents using relevant utilities is also stressed by it.
A new phishing tool called the V3B phishing kit was developed to target bank customers in the EU.
It comprises of a scenario-based credentials interception system and mirrors online banking authorization pages.
The kit is highly configurable, works with multiple countries and banks, has advanced anti-bot measures, and enables real-time interaction with victims.
Moreover, it contains a live chat system that helps fraudsters to initiate one-time password (OTP) requests and make people enter their codes unknowingly.
Prices range between $130 and $450 per month paid in cryptocurrency with regular updates that help it evade detection as new abilities emerge.
The report highlights a recent information campaign by a threat actor group, "UNC1151," targeting Ukraine, Lithuania, Latvia, and Poland with disinformation.?
This campaign involves weaponizing Excel documents to attack Windows machines. The attackers use malicious XLS files to compromise systems, which can lead to data breaches and other security issues.?
This tactic is particularly dangerous as it can evade traditional security measures and remain undetected for extended periods.?
The report highlights the importance of staying informed about emerging threats and vulnerabilities to ensure timely safeguarding measures and preventive actions.
Over 300 downloads have been made of a dangerous Python package labeled "xFileSyncerx" at the Python Package Index (PyPI).
This was a data wiping package that was detected by ReversingLabs researchers.
The person behind the sophisticated multi-step attack campaign that uses a CoinMiner executable to affect Linux devices' performance is identified as the author of this package, "sastra."
To escape detection, this malware disguises its malicious payload on different remote URLs and then gradually releases it in several steps.
Weaponized LNK files have been discovered to be used by hackers for malware deployment, where the infection chain begins with a benign-looking LNK file that has a malicious command hidden in it while pretending to be an image file.
This is followed by the HTA file being downloaded and executed using PowerShell from a remote server, inside of which there is an embedded executable file pretending to be a genuine system program.
Moreover, when these shortcuts are opened by users they are usually made to execute some PowerShell code as the study of the evil LNK files' content revealed.
Unauthorized access and control of Windows systems by hackers is due to the exploitation of flaws in Microsoft SQL (MS-SQL) servers.
This way, they may try to brute force an SQL admin access using the weak credentials after scanning for MS-SQL servers with port 1433 open.
Once they gain access, threat actors can execute malicious commands, install malware like ransomware and RATs, and potentially command whole networks.
Suspicious activities are capable of being detected early with a strong endpoint detection and response (EDR) solution that uses behavior-based monitoring.
Mitigation includes but is not limited to applying strong credentials, keeping servers patched, as well as restricting external connections to MS-SQL instances by administrators.
One new malware dissemination program makes use of the deceptive Google Chrome Update pop-ups. Malicious code is injected into the websites and asks users to upgrade their browsers to trigger the attack.
Clicking on these links will redirect them to harmful URLs that download malware like remote access trojan or infostealer.
The attack reached 341 websites, consequently users are advised not to update from pop-ups or error messages.
