Spam and phishing mail

SQL for dummies

In their attempts to bypass e-mail filtering systems and deliver their information to users, spammers often resort to all sorts of tricks. Although really new tricks (such as distributing mp3 files with voice-generated messages) are relatively uncommon, sometimes they do come up.

Kaspersky Lab analysts have recently come across a few curious samples. While masking text with noise is nothing out of the ordinary, the links were arranged in a rather unusual way.

The trick itself turned out to be rather simple and has been relatively harmless so far: a URL in the message is a request to a website that is vulnerable to SQL injection. The code yields one string, which is a spam link (in this case, a typical pharmacy ad). This is where the browser is redirected – naturally, if the original site allows such code to be executed.

Some instances we encountered during a week of observations demonstrate that following a large-scale SQL-attack LizaMoon many website owners took relevant security measures and finding suitable “donors” on a mass scale was not at all that simple.

LuminousMoth APT: Sweeping attacks for the chosen few

We recently came across unusual APT activity that was detected in high volumes, albeit most likely aimed at a few targets of interest. Further analysis revealed that the actor, which we dubbed LuminousMoth, shows an affinity to the HoneyMyte group, otherwise known as Mustang Panda.

We found new malware samples used in WildPressure campaigns: newer version of the C++ Milum Trojan, a corresponding VBScript variant with the same version number, and a Python script working on both Windows and macOS.

Ferocious Kitten: 6 years of covert surveillance in Iran

Ferocious Kitten is an APT group that has been targeting Persian-speaking individuals in Iran. Some of the TTPs used by this threat actor are reminiscent of other groups, such as Domestic Kitten and Rampant Kitten. In this report we aim to provide more details on these findings.
