上周五(2017年5月12日)全球爆发大规模的勒索病毒攻击,各学校网络为重灾区,这款勒索病毒会引诱你点击看似正常的邮件、附件或文件,病毒会将用户电脑锁死,破坏文件并修改用户桌面背景,弹出提示框告知交纳“赎金”。
感染“勒索病毒”的状况:
1.桌面及各文件夹出现未知文件(请勿打开此类文件);
2.PC中的文件被加密,被加密的文件后缀名被统一为“.WNCRY”
3.PC弹出对话框要求支付比特币赎金后才能恢复等说明。
为保证各教职工的电脑文件安全,以及避免已中毒用户感染局域网中其他主机,以下为针对此次攻击的处置办法说明:
1.开机前拔掉网线,暂时隔离各主机网络;
2.判断电脑是否感染“勒索病毒”,如果发现已被感染,不要尝试插网线或者U盘!并立即通知信息化办公室87767871;
