In desperation, many ransomware victims plead with attackers

Lucian Constantin | May 19, 2015
The shamelessness of ransomware pushers knows no bounds. After encrypting people's files and then holding them to ransom, they portray themselves as service providers offering technical support and discounts to their "customers."

After analyzing transactions involving those addresses, the FireEye researchers believe that 163 victims, or 13 percent, paid the ransom in Bitcoin. Another 20 victims paid with PayPal My Cash cards. The transactions show the TeslaCrypt gang earning $76,522 between Feb. 7 and Apr. 28, 2015.

By comparison, another file-encrypting ransomware program, called Cryptolocker, is estimated to have earned $3 million for its creators during nine months of operation until May 2014. Another program, called Cryptowall, generated over $1 million in ransom payments during a six-month period in 2014.

One good piece of news is that researchers from Cisco Systems recently developed a tool that is capable of decrypting files affected by some TeslaCrypt versions without having victims pay a ransom.
