Despite Julian Assange’s promise not to let Wikileaks’ “radical transparency” hurt innocent people, an investigation found that the whistleblowing site has published hundreds of sensitive records belonging to ordinary citizens, including medical files of rape victims and sick children.
The idea of having all your secrets exposed, as an individual or a business, can be terrifying. Whether you agree with Wikileaks or not, the world will be a very different place when nothing is safe. Imagine your all your emails, health records, texts, finances open for the world to see. Unfortunately, we may be closer to this than we think.
If ransomware has taught us one thing it’s that an overwhelming amount of important business and personal data isn’t sufficiently protected. Researcher Kevin Beaumont says he’s seeing around 4,000 new ransomware infections per hour. If it’s so easy for an intruder to encrypt data, what’s stopping cybercriminals from publishing it on the open web?
There are still a few hurdles for extortionware, but none of them are insurmountable:
- Attackers would have to exfiltrate the data in order to expose it.
Ransomware encrypts data in place without actually stealing it. Extortionware has to bypass traditional network monitoring tools that are built to detect unusual amounts of data leaving their network quickly. Of course, your files could be siphoned off slowly at this very moment disguised as benign web or DNS traffic.
- There is no central “wall of shame” repository like Wikileaks.
If attackers teamed up to build a searchable central repository for extorted data, it’d make the threat of exposure feel more real and create a greater sense of urgency.
- Maybe ransomware pays better.
Some suggest that the economics of ransomware are better than extortionware, which is why we haven’t seen it take off. On the other hand, how do you recover when copies of your files and emails are made public? Can the DNC truly recover? Payment might be the only option, and one big score could be worth hundreds of ransomware payments.
So what’s preventing ransomware authors from trying to doing both? Unfortunately, not much. They could first encrypt the data then try to exfiltrate it. If you get caught during exfiltration, it’s not a big deal. Just pop up your ransom notification and claim your BTC.
Ransomware has proven that organizations are definitely behind the curve when it comes to catching abnormal behavior inside their perimeters, particularly on file systems. I think the biggest lesson to take away from Wikileaks, ransomware, and extortionware is that we’re on the cusp of a world where unprotected files and emails will regularly hurt businesses, destroy privacy, and even jeopardize lives (I’m talking about hospitals that have suffered from cyberattacks like ransomware).
If it’s trivially easy for noisy cybercriminals that advertise their presence with ransom notes to penetrate and encrypt thousands of files at will, the only reasonable conclusion is that more subtle threats are secretly succeeding in a huge way. We just haven’t realized it yet . . . except for the U.S. Office of Personnel Management. And Sony Pictures. And Mossack Fonseca. And the DNC . . .
