Myspace redux

One of the dark attractions at DefCon is the “Wall of Sheep”. The idea is simple – a bunch of people with sniffers sitting together capturing all the unencrypted traffic that flies through the air via the free WiFi connections available at the convention.

HTTP, POP3, FTP and ICQ logins are definitely intercepted, and others may be.

I was quite suprised to see lots of Myspace accounts listed on the Wall of Sheep. It turns out that unlike other community services such as Orkut or LinkedIn, Myspace’s login is totally unencrypted and prone to sniffing.

So if you are a MySpace user, I suggest you stay away from your account next time you connect to the Internet by a public WiFi network.

The investigation described in this article started with one such file which caught our attention due to the various improvements it brought to this well-known infection vector.

Lazarus targets defense industry with ThreatNeedle

In mid-2020, we realized that Lazarus was launching attacks on the defense industry using the ThreatNeedle cluster, an advanced malware cluster of Manuscrypt (a.k.a. NukeSped). While investigating this activity, we were able to observe the complete life cycle of an attack, uncovering more technical details and links to the group’s other campaigns.

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.
