A hacking team, by name Cl0ud SecuritY, invades old LenovoEMC (formerly Iomega), NAS Appliances, steals them archives and leaves a note asking for it victims to pay between $ 200 and $ 275 to receive them data behind them.
According to entries in BitcoinAbuse, these attacks have been going on for about a month. BitcoinAbuse is a portal where users report addresses Bitcoin used in attacks ransomware, blackmail and other crimes and frauds.
Unfortunately, there are many such devices exposed on the internet. Many of them actually contained a note called “RECOVER THE FILES !!!!. Txt. ”, He asked ransom.
All notes were signed "Cl0ud SecuritY" and used the same contact email "firstname.lastname@example.org".
The recent attacks appear to be a continuation of the attacks that began last year and also targeted LenovoEMC NAS. Appliances. In last year's attacks, the hackers they used different e-mail communication and did not say what they were called. However, there are many similarities between the texts in the notes on the ransom, which makes researchers believe that it is the same hacking club.
Ο Victor Gevers, security researcher at GDI Foundation, said he has been monitoring the attacks for years and that these recent attacks appear to be the work of one "Undeveloped" group. Gevers said the hackers are not based on a complex exploit, but are targeting devices that are already exposed to the Internet.
The hackers of "Cl0ud SecuritY" claim that they have copied the victims' files and threaten to leak them if the ransom is not paid within five days.
Based on current data, hackers' notes rather they are simply trying to scare the victims to pay the ransom, while the hackers have already erased their data users.
Gevers said the attacks on LenovoEMC NAS devices were not new. Similar incidents have been reported since 1998.
Lenovo discontinued the LenovoEMC and Iomega NAS series in 2018, however, some devices are still in operation. There is one Lenovo support page on how users can secure these devices and protect their data.
In recent years, NAS devices have been targeted by DDoS malware, but also from ransomware gangs such as Muhstik, QSnatch and eCh0raix. The current attacks on LenovoEMC NAS Appliances is attempts at blackmail and not attacks ransomware, as well as hackers they have not encrypted files, but most likely deleted them.
