David Aaronovitch: 勒索软件攻击会导致公司电脑系统瘫痪,无法正常运作,犯罪分子会要求支付赎金以恢复服务或阻止数据泄露。四年前我们讨论过这个问题,但现在问题依然存在,所以我们需要了解勒索软件的运作方式、责任方以及应对措施。 Emily Taylor: 如果公司遭受勒索软件攻击,最直接的感受就是所有系统都无法使用,就像被锁在房子外面一样。你无法访问邮件、业务记录,也无法联系你的员工。犯罪分子会加密你的数据并锁定你,然后要求支付赎金,就像绑架数据一样。即使支付了赎金,也无法保证他们不会再次攻击或归还数据。支付赎金实际上是在助长这种犯罪模式。犯罪分子通常通过社交工程或网络钓鱼等手段入侵系统,伪装成可信的一方来获取个人信息或系统访问权限。SIM卡交换也是一种入侵方式,犯罪分子通过将目标用户的电话号码转移到自己控制的SIM卡上,从而重置密码并访问敏感系统。零售公司由于现金流和交易量大,以及系统瘫痪带来的巨大损失,更容易成为攻击目标。

In the past few weeks Marks & Spencer, the Co-op and Harrods have all been grappling with the effects of cyber attacks. The most profitable form of cyber attack at the moment is ransomware where criminals infiltrate computer systems, shut them down and then demand a ransom to restore services, or even to stop them publishing data they’ve stolen. This is now a global criminal industry which can affect the running of whole businesses. Marks & Spencer said this week that disruption to its online ordering service would continue throughout June and into July. David Aaronovitch asks his guests how ransomware works, who is responsible and what can be done to stop it.
