FBI Warns Ransomware Gangs Are Harassing Victims via Telephone Calls to Pay Crypto Ransoms

FBI Warns Ransomware Gangs Are Harassing Victims via Telephone Calls to Pay Crypto Ransoms

The U.S. Federal Bureau of Investigation (FBI) has
released an alert that warns private industry in the country about
incidents of harassment of victims made by ransomware gangs, such
as the well-known Doppelpaymer group.

FBI Is Aware of Cold-Calling Tactics by Ransomware Gangs

According to a PIN (private industry notification) alert
regularly
sent
to U.S. companies to inform them about the latest updates
in the cybersecurity sphere, shared by
Zdnet
, the FBI has been aware of incidents since February 2020,
where Doppelpaymer has cold-called companies to intimidate victims
by demanding them to pay a crypto ransom.

The intimidation, which had escalated to rude language, includes
threats to send individuals to the victims’ homes if they don’t
pay for the demanded money in the ransomware attack deployed by the
gang.

The FBI describes Doppelpaymer as a group of threat actors that
often demand between six and seven-figure ransoms in bitcoin during
their attacks. If victims don’t pay, then they start to
exfiltrate part of the stolen data and make “follow-on telephone
calls to victims to further pressure them to make ransom
payments.”

Zdnet said that a similar tactic was used by other now-defunct
ransomware groups, such as Sekhmet and Maze.

Usually, the group of hackers targets healthcare sectors,
emergency, and education across the globe, but they’ve been
heavily active since June 2019, said the Bureau.

In the alert, there is a recall of an incident related to
Doppelpaymer and its cold-calling tactics to harass victims:

In one case, an actor, using a spoofed US-based telephone number
while claiming to be located in North Korea, threatened to leak or
sell data from an identified business if the business did not pay
the ransom. During subsequent telephone calls to the same business,
the actor threatened to send an individual to the home of an
employee and provided the employee’s home address. The actor also
called several of the employee’s relatives.

On Dec. 7, Foxconn, a publicly traded Taiwanese company and one
of the largest electronics manufacturing firms,
suffered
a cyberattack deployed by Doppelpaymer, which asked
for a 1,804 BTC ransom.

Ransomware Attacks Are Becoming ‘Increasingly Problematic’

Brett Callow, threat analyst at malware lab Emsisoft, told
news.Bitcoin.com that ransomware “continues to become
increasingly problematic.”

The malware lab commented the following on its latest findings
in the
Q3 report
about ransomware attacks in 2020:

Ransomware remained a persistent threat in Q3 2020. Threat
actors continued to favor post-compromise deployment, often
spending significant time preparing the target environment and
exfiltrating data before delivering the ransomware payload. We also
saw more ransomware groups seek to weaponize stolen data, with
threat actors such as Avaddon, Conti, Darkside, Suncrypt and
Lockbit, among others, launching new data leak sites this
quarter.

Are the authorities starting to take ransomware attacks
more seriously? Let us know in the comments section
