In line with a recent official report by the Bleeping Computer, Argentina’s National Migration Department had to suspend border crossing for 4-hours after being hit by Bitcoin ransom attackers that occurred earlier on 27th Aug.
“The Comprehensive Migration Capture System [SICaM] that operates in global crossings was particularly affected, that caused delays in entry and exit to the national territory.”
Hackers were able to gain access to the database & steal data from the agency with the assistance of a strong cryptovirus called Netwalker.
This ransomware strain, which was primarily discovered earlier in September last year, uses sophisticated techniques to encrypt files with AES cipher.
Not to permit the ransomware to duplicate itself on other computer networks, that need to be shut-down.
Initially, the hackers demanded a $2 Mln worth of Bitcoin to unlock files, consistent with the dark web payment page associated in their ransomware note. Within one week, this sum increased to 355 BTC around $4 Mln at the present exchange rates.
The ransom attempt isn’t going so well as so far since the immigration agency refuses to negotiate with the attackers. It claims that no personal, or corporate data has been compromised, & they are not concerned about decrypting the data hacked.
Bitcoin Ransom Attacks Are On A Boom
Also earlier in July, Telecom Argentina, the leading telecommunications operating within the country, also became a victim of ransomware, with hackers requesting $7.5 Mln worth of Monero [XMR].
The attack lasted for over 3-days but Telecom Argentina was able to restore access to affected systems without having to distribute the hefty ransom.
