In this blog post we confirm that the Avatar rootkit continues to thrive in the wild, and disclose some new information about its kernel-mode self-defense tricks. We continue our research into this malware family.
Java has been – and still is – one of the more problematic issues security-wise. A website showing song lyrics from Golden Earring's Radar Love shows off problems that can leave users at the mercy of Java attacks.
A new paper aims to profile the victims most likely to fall for a phishing attack. But what is less clear is how you develop a profile while avoiding the pitfalls of stereotyping.
Recently, our anti-virus laboratory discovered an interesting new modification of a file virus known as Expiro which targets 64-bit files for infection.
