AUSCERT Week in Review for 17th August 2018

AUSCERT Week in Review
17 August 2018

Greetings,
Another week gone by, and this one has not been any thinner in bulletins to process.
Have you ever applied lots of pressure to a wet bar of soap? It may be a worth-while experiment to perform the next time you get access to a soap bar if the physics are not quite understood.
Well, entities are a bit like a bar of wet soap and are keen to avoiding legal problems, whilst maintaining a loyal and satisfied customer base.  After all that is how “quality” is defined, a satisfied customer base.  This may soon become a more complicated juggling act for organisations handling user data either, in transit or at rest, from a service they provide or equipment they manufacture.  Trying to squeeze access to data may result in organisations deciding to relinquish any possibility of access to this user data as legal ramification increase. Adding the risk of time served may alter the way an organisation may provide a service or build a product. Squeezing organisation hard in this manner may diminish, as the chance to get to the data sought slips away. So, should organisations deal with user data, at rest or in transit, from services or equipment manufactured, then perhaps the first news story of this week is worth while to look at and keep an eye if this legislation passes.  For if it does, organisations may have to re-assess their policy, denying themselves access to user-submitted data, lest time be served.     

As for the news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week:

Excerpt:
“Security and user privacy protections included in browsers, ad blockers, and anti-tracking extensions are not as secure as everyone believes, a team of three academics from the Catholic University in Leuven, Belgium (KU Leuven) have revealed yesterday.

Their work consisted of analyzing anti-tracking settings that are built into modern browsers, but also the ones provided by some popular extensions (add-ons).”

Excerpt:
“A new variant of the Princess Locker ransomware is being distributed called Princess Evolution. Like its predecessor, Princess Evolution is a Ransomware as a Service, or RaaS, that is being promoted on underground criminal forums.

As this ransomware is being distributed through different affiliates, there are numerous methods that are possibly being used to distribute this ransomware…

..Unfortunately, at this time there is no known way to decrypt files encrypted by Princess Evolution. For those who are interested in discussing this ransomware or receiving support, you can use our dedicated Princess Evolution Support & Help topic.”
