Stalkerware poses particular challenges to anti-virus products

Posted by Martijn Grooten on Oct 31, 2019

Malware used in domestic abuse situations is a growing threat, and the standard way for anti-virus products to handle such malware may not be good enough. But that doesn't mean there isn't an important role for anti-virus to play.

The debate on responsible disclosure is about as old as IT security itself. In a guest post for Virus Bulletin Robert Neumann suggests we need to reconsider a one-size-fits-all solution and instead look for a well-respected independent organization to handle security issues.

WannaCry shows we need to understand why organizations don't patch

Perhaps the question we should be asking about WannaCry is not "why do so many organizations allow unpatched machines to exist on their networks?" but "why doesn't patching work reasonably well most of the time?"
For the past few days, the world of Infosec on Twitter has tried to find as many ways as possible of saying "we told you so". To be fair, it's true – we did tell you so: for… https://www.virusbulletin.com/blog/2017/may/wannacry-shows-we-need-understand-why-organisations-dont-patch/

Modern security software is not necessarily powerless against threats like WannaCry

The WannaCry ransomware has affected many organisations around the world, making it probably the worst and most damaging of its kind. But modern security is not necessarily powerless against such threats.

Consumer spyware: a serious threat with a different threat model

Consumer spyware is a growing issue and one that can have serious consequences: its use is increasingly common in domestic violence. But do our threat models consider the attacker with physical access to, and inside knowledge of the victim?

Why the SHA-1 collision means you should stop using the algorithm

Realistically speaking, if your software or system uses the SHA-1 hashing algorithm, it is unlikely that it will be exploited in the foreseeable future. But it is also extremely difficult to be certain that your system won't be the exception.
Unexpected though it may have been, the SHA-1 collision found by researchers at CWI Amsterdam and Google earlier this year is one of the biggest security stories of 2017 thus far.… https://www.virusbulletin.com/blog/2017/03/why-sha-1-collision-means-you-should-stop-using-algorithm/
