Researchers Uncover SnakeKeylogger Attacks, Techniques & Tactics

Possibility actors exhaust keyloggers to capture aloof recordsdata by recording keystrokes on infected units, as covert tactics and tactics enable them to assign shut precious recordsdata with out the victim’s recordsdata.

Governments or menace actors can deploy Keyloggers as espionage tools to come by intelligence or computer screen their targets.

Lately, the cybersecurity researchers at Splunk Possibility Analysis Team unveiled SnakeKeylogger attacks, tactics, and tactics.

SnakeKeylogger Attack Programs

Snake Keylogger steals credentials and logs keystrokes. It changed into as soon as developed in .NET and captures screenshots, clipboard recordsdata, browser credentials, and machine recordsdata.

It makes exhaust of FTP, email, and Telegram for recordsdata exfiltration. Various C2 infrastructure enhances the operational effectiveness in opposition to old defenses.

Snake Keylogger spreads by draw of phishing and obfuscates code with cryptors/loaders to evade sandboxes. This loader parses .RSRC entry identify computes the SHA256 hash of the major string for AES-ECB decryption of encrypted .RSRC payload.

Whereas its advanced tactics grief the diagnosis. Decrypted recordsdata has but any other loader with two AES-ECB encrypted .RSRC entries the usage of diversified keys.

Decrypting these unearths a RUNPE injector and the particular Snake Keylogger payload.

The Snake Keylogger gathers machine recordsdata, equivalent to OS model, RAM, and HDD principal capabilities, and codecs recordsdata sooner than sending it to the C2 server.

It queries reallygeoip[.]org to stumble on the host machine geographically, extracting city, nation, latitude, longitude, space, and timezone.

This recordsdata boosts situational consciousness for centered attacks.

It makes exhaust of registry traipse keys for persistence and involves a ‘Atomize Switch’ that terminates if the make date is sooner than the present date.

This tactic is an anti-sandbox approach that helps to evade security detection.

Snake Keylogger on the whole makes exhaust of Crypter or loaders, requiring reverse engineering to bypass its date test, at the side of complexity for

It prompts particular person picks with substitute.exe, the usage of “/T” for the extend sooner than cleanup. It terminates security tools’ processes to evade detection and maintains a listing of sandbox IPs.

Snake Keylogger checks for particular IP addresses sooner than executing the payload. It exfiltrates the machine, community, and browser credentials to C2 if obvious.

This atmosphere detection evades the safety checks. It targets notable browsers and email/file clients for credentials and credit rating cards.

Harvests Outlook profiles from the registry for usernames/passwords. Steals clipboard recordsdata like passwords, cards, and textual snarl for recordsdata theft.

This keylogger periodically captures screenshots equivalent to “Screenshot.jpg” in the particular person’s Documents folder for visible recordsdata theft.

Its core ability is covert keystroke logging to harvest credentials and variety aloof recordsdata, reads Splunk file.

It initiates by contacting the C2 server, verifying exercise if the response consists of “#$0#”. Admire Agent Tesla, it makes exhaust of FTP, email, and Telegram C2 channels specified by the config to exfiltrate recordsdata.
