I believe there’s a pretty clear consensus within the industry that ransomware should not be mistaken anymore to limit itself to just encrypting files and demanding payment for a decryption key. Dubbed by F-Secure “Ransomware 2.0”, now the standard practice for ransomware groups includes also stealing files from the target company in order to increase the leverage for ransom. Proper backups are an antidote to encrypted files but won’t help against the threat of stolen data being leaked.
Although this double extortion scheme has been the new modus operandi only since late 2019, cyber criminals are already looking for additional ways to apply pressure to their victims. This is where Ransomware 3.0 comes in.

If an email sounds too good to be true, we’ve learned to dismiss it as phishing or otherwise fraudulent, even if it managed to evade the email client’s junk filters. However, I’ve seen a rise of new type of automated emails that deserve a closer look, as they behave quite differently from your average spam. These emails are from seemingly legitimate businesses, targeting specific email addresses associated with Instagram Creator accounts, and offering some type of an influencer marketing deal.
Global influencer marketing spend is growing rapidly, and Instagram grabbed a lion share – 8 billion dollars – of it during 2020. So, it’s not out of the question for even smaller Creator accounts to get approached by (smaller) brands, but there’s definitely something fishy about the following emails. Let’s look at some examples.

Recently I was invited to KOVA Esports podcast to talk about cyber security, online privacy and identity management from the perspective of gamers and gaming industry in general. Hosted by KOVA’s General Manager Timo Tarvainen and joined by their streamer Teemu “Spamned” Rissanen, we had a great one-hour long discussion. This post covers my own notes about the things we mentioned, source links included, and further expands on some of the topics. Links to the podcast episode can be found on the bottom of the page. Enjoy!

WhatsApp being a closed source app, owned and operated by Facebook, there’s not much you can do to protect your privacy from that angle. You can, however, limit the amount of data you expose to other WhatsApp users. These are all the privacy settings and tricks for WhatsApp you should be using.

Last year I took a first look at a phishing campaign that was interestingly targeting YouTube channel owners’ email addresses. The aim of the campaign was to guide people to fake YouTube sign in page and phish their login credentials. Note, this did not target YouTube accounts in general, but actual channels. These were my main findings:
- Despite being hilariously obvious, first four of these were not caught by ProtonMail’s spam filter
- Out of several YouTube channels I manage, only one has been targeted
- Same email was CC’d to others
- Unclear where they have found my email address
- Senders’ email service providers started as Russian. Little to no typosquatting involved.
- After few iterations, phishing content seems to have reached its final form (for now)
The campaign came in a burst, stopping as suddenly as it had started. Now after a couple of months it has started again, and it’s time to re-examine what has changed.

Continuing my seemingly never-ending quest of digging through privacy policies, this time I analyzed how the most popular wearables companies handle their customers’ data. Fitbit, Biostrap, Motiv, Oura and Whoop all are on the cutting edge of health technology, but are their privacy practices on par with that or not?
A fellow biohacker Alex Fergus provided me with the opportunity to publish my little research article on his website. Over the years he has published tons of information on fitness, sleep and – of course – health gadgets. Few days ago he published the most comprehensive red light panel comparison I’ve ever seen, analyzing everything from EMF levels to irradiance and LED flicker. Let’s just say he knows his stuff, so I’m excited to try to match his professionalism on that space with mine about privacy.
I believe it’s time for the biohacker community to start valuing their data more. In my guest blog post you’ll learn:
- What data do these wearables collect?
- Are they selling or exchanging data with third parties?
- Data retention – how long are they storing your data?
- What can you do?
- And more…
So head over to alexfergus.com and learn everything you need to know about wearables and privacy!
During past few months I’ve witnessed and been targeted by rather simple, but still interesting phishing campaign. Well, not me personally, but instead a YouTube channel that I run. This campaign has noticeably sped up in November, so I decided to take a closer look at these phishing emails and share with you my findings.
