USB Keylogger | Breaking Cybersecurity News | The Hacker News

A Chinese threat actor has developed new capabilities to target air-gapped systems in an attempt to exfiltrate sensitive data for espionage, according to a newly published research by Kaspersky yesterday. The APT, known as Cycldek, Goblin Panda, or Conimes, employs an extensive toolset for lateral movement and information stealing in victim networks, including previously unreported custom tools, tactics, and procedures in attacks against government agencies in Vietnam, Thailand, and Laos. "One of the newly revealed tools is named USBCulprit and has been found to rely on USB media in order to exfiltrate victim data," Kaspersky said. "This may suggest Cycldek is trying to reach air-gapped networks in victim environments or relies on physical presence for the same purpose." First observed by CrowdStrike in 2013, Cycldek has a long history of singling out defense, energy, and government sectors in Southeast Asia, particularly Vietnam, using decoy documents th...

Last year, a white hat hacker developed a cheap Arduino-based device that looked and functioned just like a generic USB mobile charger, but covertly logged, decrypted and reported back all keystrokes from Microsoft wireless keyboards. Dubbed KeySweeper , the device included a web-based tool for live keystroke monitoring and was capable of sending SMS alerts for typed keystrokes, usernames, or URLs, and work even after the nasty device is unplugged because of its built-in rechargeable battery. Besides the proof-of-concept attack platform, security researcher Samy Kamkar, who created KeySweeper, also released instructions on how to build your own USB wall charger. Now, it seems like hackers and criminal minds find this idea smart. The FBI has issued a warning advisory for private industry partners to look out for highly stealthy keyloggers that quietly sniff passwords and other input data from wireless keyboards. According to the advisory, blackhat hackers have developed their...

Security researcher has developed a cheap USB wall charger that is capable to eavesdrop on almost any   Microsoft   wireless  keyboard . MySpace mischief-maker Samy Kamkar has released a super-creepy keystroke logger for Microsoft wireless keyboards cunningly hidden in what appears to be a rather cheap, but functioning USB wall charger. The stealthy Arduino-based device, dubbed " KeySweeper ", looks and functions just like a generic USB mobile charger, but actually sniffs, decrypts, logs, and reports back all keystrokes from a Microsoft wireless keyboard. " KeySweeper is a stealthy Ardunio-based device camouflaged as a wall charger that wirelessly sniffs, decrypts, logs and reports-back all keystrokes from any Microsoft wireless keyboard in the vicinity," Kamkar said. The security researcher has also released instructions on how to build the USB wall charger online and surprisinglyits is cheap to build and quite capable. KeySweeper includes a web...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...
