The TJX Hacker Black SEO Campaign

While I was reading the Wired article on how Alberto Gonzalez, the TJX hacker who caused $171.5 million in losses, was sentenced to 20 years in prison, I came across an interesting black SEO campaign that distributes fake AVs through Google.

Here’s how the Google SERP looked like after my innocent search for this hot topic:

As you can see, some odd looking links are among the first results. And those links appeared very recently in the Google results page, within the last hour to be more specific. Still, the link that showed up just “9 minutes ago” is actually the second result in the Google ranking, right after the Wired article. Makes you think of how hard the cybercriminals are working to bypass Google’s algorithms, eh?But what’s with these links? Well, they might look like legitimate Wikipedia articles to the untrained eye, but they’re not. These randomly named PHP scripts were uploaded to compromised legitimate websites and then spammed using black SEO techniques right to the top of the Google results page.

The URLs look like this:
h**p://*****ms.net/yvmay.php
h**p://***************ring.com/cedxz.php
h**p://*****m.org/apyhe.php
h**p://*****w.com/johzs.php
h**p://*****pod.com/oagnz.php
h**p://**********arm.com/lekgz.php
etc

All these links are not malicious by themselves, but they serve as redirectors – sending all the traffic towards one main malicious website hosted on h**p://************.**rg.pl/ which is distributing fake antivirus software (or rogue AVs) that looks like this:

We were able to reproduce the attack on almost all of the hot searches on Google at that time.

Of course, this is simply yet another example of how cybercriminals are using good or bad
news
happening around the world to try and push out their malware.

A lot of cyber security depends on each and every one of us – be careful out there and, if in doubt, don’t click! 🙂

Sunburst backdoor – code overlaps with Kazuar

While looking at the Sunburst backdoor, we discovered several features that overlap with a previously identified backdoor known as Kazuar. Our observations shows that Kazuar was used together with Turla tools during multiple breaches in past years.

Lazarus covets COVID-19-related intelligence

As the COVID-19 crisis grinds on, some threat actors are trying to speed up vaccine development by any means available. We have found evidence that the Lazarus group is going after intelligence that could help these efforts by attacking entities related to COVID-19 research.

Sunburst: connecting the dots in the DNS requests

We matched private and public DNS data for the SUNBURST-malware root C2 domain with the CNAME records, to identify who was targeted for further exploitation. In total, we analyzed 1722 DNS records, leading to 1026 unique target name parts and 964 unique UIDs.

What did DeathStalker hide between two ferns?

While tracking DeathStalker’s Powersing-based activities in May 2020, we detected a previously unknown implant that leveraged DNS over HTTPS as a C2 channel, as well as parts of its delivery chain. We named this new malware “PowerPepper”.
