US-CERT has received reports of increased activity concerning an apparently
DHS-themed ransomware malware infection occurring in the wild. Users who are
being targeted by the ransomware receive a message claiming that use of their
computer has been suspended and that the user must pay a fine to unblock it.
One iteration of this malware also takes a webcam (if available) photo or video
of a recipient and posts it in a pop-up to add to the appearance of legitimacy.
The ransomware falsely claims to be from the U.S. Department of Homeland
Security and the National Cyber Security Division.
Users who are infected with the malware should consult with a reputable
security expert to assist in removing the malware, or perform a clean
reinstallation of their OS after formatting their computer's hard drive.
US-CERT and DHS encourage users and administrators not to pay the
perpetrators and to report the incident to the FBI at the
Internet Crime Complaint Center (IC3).
Use caution when encountering these types of email messages and take the
following preventive measures to protect themselves from phishing scams and
malware campaigns that attempt to frighten and deceive a recipient for the
purpose of illegal gain.
?
Do not click on or submit any information to
webpages.
?
Do not follow unsolicited web links in email
messages.
?
Maintain up-to-date antivirus software.
?
Users who are infected should change all
passwords AFTER removing the malware from their system.
