Microsoft has reported a massive phishing campaign that uses an Excel attachment as bait. The phishing email looks like it is from the Coronavirus Research Center of John Hopkins University–a well known medical organization in the US. The email includes an Excel attachment that is disguised as an updated list of Coronavirus-related deaths, but the file actually contains a hidden piece of malware.
Whether you’re working from home or trying to stay in touch with loved ones, video conferencing apps like Zoom are becoming the new normal. Cybercriminals have exploited this type of application before, but their latest scam may be the trickiest yet.
Just as you should take precautions to make sure returning workers aren't sick, you will want to make sure returning computers are not sick as well. It is imperative that incoming computers are checked for infections and safety measures are performed before you allow them back onto the corporate network.
The Maze group, which is behind the relatively new REvil/Sodinokibi ransomware, has doubled down on the malicious functionality of their malware. The ransomware now exfiltrates large amounts of live data before encrypting the victim’s systems; and the Maze group threatens to dump that data online if the victims don’t pay. Not wanting to be left behind in how much damage they can do and potential money they can extort from businesses, other cybercriminal organizations are starting to jump on this bandwagon as well, including the LockBit ransomware developers.This means that whereas before “ransomware was just ransomware” (which is a bad enough crisis for a business), now it also must be considered a potential data breach, requiring all of the costly and potentially embarrassing notifications, forensic investigations, legal costs, and disclosure involved in that process. Also, if you’re in NYS, don’t forget about SHIELD data breach notification requirements.
If you’re not already doing everything you can to prevent these kinds of attacks from victimizing your business, the potential costs of an incident have just increased exponentially. Insurance and good backups are no longer good enough to weather the business disruption of a ransomware incident.
