Incidents

Echoes from the past

It seems from information on the Danish web site of Medion that some of the laptops they shipped recently were infected with the boot sector virus Angelina. This virus, which infects the boot sector of floppy disks and the MBR (Master Boot Record) of hard disks, dates from the mid-1990s.

Once commonplace, such threats are now rare. And on the face of it, you might not expect viruses as old as this to be still around. But incidents like this remind us that they haven’t completely disappeared.

For those of you who haven’t had to grapple with such viruses, they infect when the machine is booted from an infected floppy disk. Of course, this typically happens by accident, when the user forgets that there’s a floppy disk in the drive. They infect at boot-up, before the operating system loads, so they will infect any PC configured to boot from the floppy drive. However, they only spread under DOS and (under specific conditions) Windows 9x. This is why they’re not very common.

So, if such threats are rare, do we detect them? Absolutely, you never know when such ‘legacy’ threats might put in an appearance.

Reports

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.

WildPressure targets the macOS platform

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.

Andariel evolves to target South Korea with ransomware

In April 2021, we observed a suspicious Word document with a Korean file name and decoy. It revealed a novel infection scheme and an unfamiliar payload. After a deep analysis, we came to a conclusion: the Andariel group was behind these attacks.
