DHS Warns of Potential Iranian Cyberattack | Avast


Expecting retaliation for the U.S. assassination of Iranian Gen. Qasem Soleimani, the Cybersecurity and Infrastructure Security Agency (CISA), which is a branch of the Department of Homeland Security, has dispatched a notice informing businesses across America about the looming threat of both cyber and physical attacks. Among the potential risks, CISA lists cyberattacks against the finance, energy, and telecommunications industries, cyber-enabled espionage and intellectual property theft, disinformation campaigns, and physical attacks using explosives and unmanned aircrafts. CISA urges all organizations to fortify their cyber and physical defenses, providing protection-forward checklists on how they can do so in the notice. Heightened awareness and increased vigilance rank as the first immediate steps, along with creating an offline data backup.

The attackers told the BBC that the ransom demand was $6 million. Additionally, attackers say they are in possession of 5GB of sensitive customer data, which they will sell on the dark web if Travelex does not pay. Travelex maintains that customer data has not been leaked. 

Snake Ransomware enables large-scale strikes

A new ransomware strain threatening enterprise-sized computer networks was discovered and analyzed by researchers who deemed it sophisticated and as-of-yet uncrackable. Upon initial infection, Snake Ransomware preps the targeted network for attack by deactivating many of the data control tools.
