How to remove WINELOADER Backdoor

0
WINELOADER is a modular backdoor malware that has recently been observed targeting European officials, particularly those with connections to Indian diplomatic missions. This backdoor is part of a sophisticated cyber-espionage campaign dubbed SPIKEDWINE, which is characterized by its low volume and advanced tactics, techniques, and procedures (TTPs). The campaign uses social engineering, leveraging a fake wine-tasting event invitation to lure victims into initiating the malware's infection chain. WINELOADER is a previously undocumented backdoor that is modular in design, meaning it has separate components that can be independently executed and updated. The backdoor is capable of executing commands from a command-and-control (C2) server, injecting itself into other dynamic-link libraries (DLLs), and updating the sleep interval between beacon requests to the C2 server. The malware uses sophisticated evasion techniques, such as encrypting its core module and subsequent modules downloaded from the C2 server, re-encrypting strings dynamically, and employing memory buffers to store results from API calls. It also replaces decrypted strings with zeroes after use to avoid detection by memory forensics tools.

How to remove StrelaStealer

0
StrelaStealer is a type of stealer-type malware that specifically targets email account login credentials. It was first discovered by researchers in November 2022 and has been observed to be distributed using spam emails targeting Spanish-speaking users. The malware is designed to extract email account login credentials from popular email clients such as Microsoft Outlook and Mozilla Thunderbird. Once the malware is loaded in memory, the default browser is opened to show the decoy to make the attack less suspicious. StrelaStealer details Upon execution, StrelaStealer searches the '%APPDATA%\Thunderbird\Profiles' directory for 'logins.json' (account and password) and 'key4.db' (password database) and exfiltrates their contents to the C2 server. For Outlook, StrelaStealer reads the Windows Registry to retrieve the software's key and then locates the 'IMAP User', 'IMAP Server', and 'IMAP Password' values. The IMAP Password contains the user password in encrypted form, so the malware uses the Windows CryptUnprotectData function to decrypt it before it's exfiltrated to the C2 along with the server and user details. It is crucial to follow the removal instructions in the correct order and to use legitimate and updated anti-malware tools to ensure the complete eradication of the malware. After removing the malware, it is also essential to change all passwords immediately, as the stolen credentials may have been compromised.
