Arcane Stealer V malware provides threat actors with cheap information stealer

  • Researchers at Fidelis identified a net information stealer, dubbed Arcane Stealer V, being sold online for approximately 9 US dollars. The malware was acquired by the researchers in July 2019 and appears to be built and distributed by a Russian speaking threat actor.
  • The malware can steal passwords, cookies, and forms from a range of browsers including Chrome, Comodo, and Amigo. Arcane Stealer V also collects cryptocurrency wallets files, Telegram sessions, Steam community data, OS data, and more. 
  • The researchers stated that Arcane Stealer will likely be popular with lower skilled threat actors but lacks ‘traversal, propagation, or destructive capabilities’ that would make it more attractive to APTs.

Ongoing Campaigns

Adobe and Google open redirects used by phishing campaigns to add legitimacy

Security researcher publishes iOS jailbreak that exploits Bootrom vulnerability

  • A security researcher, going by the Twitter handle axi0mX, published a new jailbreak that affects all iOS devices running on A5 to A11 chips. Vulnerable devices include iPhone 4S to iPhone 8 and iPhone X. The jailbreak does not affect A12 or A13 chipsets.
  • Abusing a vulnerability found in Apple’s Bootrom, the exploit, dubbed Checkm8, can allow phone owners to take full control over their device. Unlike the typical iOS operating system jailbreaks, the Bootrom jailbreak can’t be patched. Software-based jailbreaks are usually patched within weeks, whereas this vulnerability would need a physical modification to the device chipsets, which would require callbacks or mass replacements from the company.
