The blackmail virus is rampant
In recent years , Computer and Internet applications have been popularized and developed in China , Has penetrated into every corner of society , The government , economic , military , social , Culture and people's life are increasingly dependent on computers and networks , E-government , Paperless office 、MIS、ERP、OA And other systems are also widely used in enterprises and institutions . However , The network security situation is becoming more and more serious , similar WannaCry Worm extortion viruses continue to emerge and break out , Always ring the alarm for everyone .
Especially in recent years , Blackmail virus “ The meteoric rise ” Make the already severe data security even more frost on the snow , Almost every few days , Enterprises and institutions will be recruited . Blackmail virus , It's a bad thing 、 A very harmful computer virus , Mainly by mail 、 Trojan horse 、 Website hang horse 、 Exploit 、RDP Weak password brute force cracking and other forms of communication . Because this virus uses various encryption algorithms to encrypt files , Once infected, it is generally impossible to decrypt , Only the ransom paid to the blackmailer can be decrypted . If the infected person refuses to pay the ransom , You can't get the decryption key , Unable to recover file . The following figure shows the distribution of industries attacked by blackmail virus .
in addition , The lack of regulation of virtual currency , Make it impossible for the blackmailer to recover the ransom , Directly promoted the spread of blackmail virus, unscrupulous , intensified .
Current situation of extortion virus protection
Common blackmail virus prevention methods
The most common method is to patch the operating system , Deploy antivirus software , Deploy firewall , Do data backup . For known viruses , The effect is very obvious , It can basically have an immediate effect ; But for unknown viruses , These traditional methods are somewhat inadequate , I don't know which loophole the blackmail virus will take to penetrate . At present, the specific preventive measures are :
1、. Data backup and recovery : Reliable data backup can minimize the loss caused by blackmail software , But at the same time, these data backups should also be protected , Avoid infection and damage .
2、 Be careful with documents from unknown sources , Unfamiliar emails and attachments should also be opened carefully .
3、 Install the safety protection software and keep the protection on .
4、 Timely installation Windows Bug fix !
5、 meanwhile , Please also make sure that some commonly used software is kept up to date , especially Java,Flash and Adobe Reader Applications such as , Older versions often contain security vulnerabilities that can be exploited by malware authors or disseminators .
6、 Set a strong password for your computer —— Especially the computer with remote desktop . And don't reuse the same password on multiple sites .
7、 Safety awareness training : It is very necessary to carry out continuous safety education and training for employees and computer users , Users should be made aware of the way blackmail software is spread , Like social media 、 social engineering 、 Untrusted website 、 Untrusted download source 、 Spam, phishing, etc . Through case education, users have certain risk identification ability and awareness .
There are still potential safety hazards
Although many preventive measures have been taken , Business server 、 Employee terminal computer 、 Production line management console, etc , There are still many risks of virus invasion , for example :
The backed up data may also be encrypted by blackmail virus ;
The operating system in the network isolation environment cannot be patched in time , It makes the virus easy to take advantage of it ;
The virus database of anti-virus software is not updated in time , Can't find the virus ;
U Disk randomly copies data into the virus .
Intelligent device terminal solutions
Commonness analysis of blackmail virus
Shenxinda company is a professional data security manufacturer in China , The species and behavior of blackmail virus were analyzed . There are many kinds of blackmail viruses ( Here's the picture ), New extortion viruses are still emerging , And follow the blackmail virus , The method of chasing and preventing must be very passive .
Extortion virus species
Through the analysis of extortion virus behavior , It is concluded that the ultimate purpose of these virus Trojans is to tamper with data , To extort .
Summary of intelligent device terminal solutions
Shenxinda intelligent device terminal solution is from the perspective of data protection , By mirroring the operating system , The snapshot is extracted from the working scene 、 Business data access behavior 、 Business scenarios, etc , Establish a safe container , Sign the host operating system and business program , Verification audit of data access , Put an end to illegal data use , In the white list mode of keeping constant and responding to changes , Protect the operating system and data , Stop extortion virus and other viruses 、 Hacker attacks .
Shenxinda intelligent device terminal solution subverts the traditional security defense concept . Even after losing system administrator privileges , Still able to defend effectively , Ensure the security of data and business systems , So as to realize the defense mechanism of the last meter .
