Israel Securities Authority chief Shmuel Hauser said in a letter to Ittai Ben Zeev, the CEO of the TASE, that cryptocurrency companies should be banned from entering the exchange via a "back door", or through the activities of an existing company that is already listed on the exchange until a proper regulatory process is in place for dealing with these kind of companies.

Hauser’s letter to the TASE CEO came after the regulator delivered comments at the Hi-tech Growth and Debt Financing Conference held yesterday at the TASE that he would not allow companies whose values are based on bitcoin values, like Natural Resources Holdings (Mashabei Teva), to be included in the TASE indices.

"Mashabei Teva" is the Israeli brand of TASE-listed Natural Resource Holdings, a precious metals company whose stock price jumped after it announced a switch to mining cryptocurrencies.

After Hauser’s comments on Tuesday Natural Resources shares plunged more than 25%.

Recently, we have reported that Israeli bank Leumi blocked transactions of popular cryptocurrency services.

Ryuk Ransomware Team to Get 705 BTC

CrowdStrike and McAfee believes the program was created and supported by Russians

In less than six months, hackers got 705 bitcoins through Ryuk ransomware, reports The Block.

Until recently, the group of hackers GRIM SPIDER behind Ryuk was supposed to be operating from North Korea. However, according to the companies CrowdStrike and McAfee, the program was created and supported by Russian hackers.

Ryuk is distributed via email-phishing, where the TrickBot Trojan is involved. The main objectives of the ransomware program are large companies and government organizations. Ryuk blocks the victims' hard drives until they pay the ransom. The amount of the latter often depends on the size and significance of the organization.

The program is "famous" for the impressive amounts of required buybacks:

To date, the lowest observed ransom was for 1.7 BTC and the highest was for 99 BTC. With 52 known transactions spread across 37 BTC addresses (as of this writing), GRIM SPIDER has made 705.80 BTC, which has a current value of $3.7 million. With the recent decline in BTC to USD value, it is likely GRIM SPIDER has netted more.


705 bitcoins at the current exchange rate is about $ 2.6 million.
