Anonymous Sudan, the hacking gang targeting SAS Airlines in a five-day cyberattack, has increased its latest ransom demand from$175,000 to$3 million, according to an announcement posted on the encrypted Telegram channel. 

The group initially demanded$3,500 when its members launched a series of denial-of-service attacks against the airline last week. SAS's website and mobile app were relentlessly taken offline in these attacks. Problems with SAS' online services were quickly noticed by customers trying to log in to their accounts almost immediately after the attacks. SAS Airlines has not acknowledged a specific cause for the online disruptions. Instead, it has issued an apology for technical difficulties.

The Sudan-based hacking group, which usually targets its victims for mostly religious reasons, first emerged in January this year. The group is linked to KillNet and UserSec, two hacking groups linked to Russia, in an ongoing campaign against NATO.
