Malware

New KPOT version silently steals account information and more

  • Proofpoint researchers observed new samples of KPOT malware, tracked as v2.0, being distributed via spam emails that lure users into opening malicious attachments.
  • KPOT is a stealer that focuses on exfiltrating account information and other data from various software applications and services. For example, it is capable of stealing cookies, passwords and autofill data from browsers, or account details for Skype, Telegram, Discord, Steam, Jabber, and more.

FBI and DHS discover new ELECTRICFISH malware used by Lazarus Group

  • The FBI and the US Department of Homeland Security released a report detailing a new malware strain dubbed ELECTRICFISH, used by the Lazarus Group to exfiltrate data from victims.

Vulnerability discovered in ‘Unhackable’ eyeDisk USB stick

  • EyeDisk is a USB stick that uses iris recognition to unlock a person’s drive. Pen Test Partners researcher David Lodge tested the USB stick and discovered that in order to work, the retinal mechanism has to pass something to the device in order to unlock the associated contents.
  • Lodge activated packet sniffing using the packet analyser Wireshark and found that within the CDB’s string was his password and another 16-byte hash, which he assesses could have been an iris hash.
  • In addition, he also discovered that the device unlocks the volume by sending a password through in plaintext.  Obtaining the password/iris can be achieved by sniffing the USN traffic to get the password/hash in cleartext.
