Thousands of Android Users fall Victim to Giveaway Fraud

Upwards of 65,000
Android users
were potentially compromised after installing a malicious app
promising free giveaways. Over the year the scam was in effect, roughly 5,000

claimed its first victim, Brookfield Residential,  after operating for nearly two weeks. The
North American real estate developer recently noticed unauthorized access to

Cryptominers Caught Using AI

Researchers have been at work creating an AI
to detect malicious cryptocurrency miners while avoiding
legitimate ones. The detection method compares currently running miners to
graphs of both legitimate and illegitimate miners and monitors changes between
the processes being used and the scheduling of mining activity. This type of
detection may be put to use to decrease the overall use of malicious code that
can often tax the system’s CPU usage to max capacity.

of the attack remains unclear and officials are still working to determine the
effects on the 25,000 enrolled students.

Maze Ransomware Cartel Adds New Variant Team

addition to new revenue streams from its partnership with the organization, cartel
members also benefit from access to the Maze Group’s resources including
obfuscation techniques and posting cartel member’s stolen data to their dedicated
leak site.
