Bitcoin extortion email 2019
Ransomware is a type of malware from cryptovirology that threatens to publish the victim's personal data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system so that it is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment.

On Thursday, from New York to San Francisco, businesses, universities and news agencies across the country received emails trying to extort bitcoin from them to prevent the release of videos of a compromising sexual nature. Often in such cases, people want to keep the situation quiet to avoid embarrassment. But this attack was broadcast to the world because the attackers attached bomb threats to their ransom messages. In every threatened city across the country, police had no choice but to respond to the threats.
Ultimately, they discovered there were no bombs anywhere. And it turned out the threats of extortion videos were fake as well. Those threats also turned out to be fake. In May, over schools in the UK received bomb threat emails. Authorities determined all these attacks were phony, but the schools were thrown into a tailspin in the process. Fortunately, no bombs were found but only after many hours were expended searching and time wasted by evacuations and other disruptions.
An FBI statement said, "We are aware of the recent bomb threats made in cities around the country, and we remain in touch with our law enforcement partners to provide assistance. As always, we encourage the public to remain vigilant and to promptly report suspicious activities which could represent a threat to public safety. Other law enforcement agencies also confirmed the threats were hoaxes, including New York Police Department Counterterrorism Bureau, and agencies from Raleigh to Chicago to San Francisco and dozens of other cities affected by these fake threats.
And, it appears they consider the disruption itself worth their effort. Sending the same email to tens of thousands of people costs almost nothing and if just one pays, it's been worth it. The ease with which an attacker can craft such a large-scale disruption has ignited concern. While these Bitcoin demands seem over the top, the disruption can cost millions in police time alone, and the potential for this to escalate with copycats is always alarming.
It could be that more will come because cybercriminals are lazy and copycat attacks pop up very quickly. I expect this to pick up over the next year. Once people figure out that this is a way to extort money, they will use it. Read full Hoax bomb threat cyber extortion email article.
