英国几大银行储备比特币以备支付黑客赎金

IT专家说,伦敦几大银行都在囤积比特币用以向威胁整垮他们关键IT系统的网络罪犯支付赎金。各银行现在认为,比起大规模网络攻击带来的威胁,支付赎金更合算。

据《卫报》报道,支付比特币赎金似乎更可取是因为即使高级警官注意到了此类事件,警方资源也不足以应对显著增加的网络攻击案件。

英国政府前科技大使兼国际电子犯罪大会主席Simon Moores博士没有提到银行在购买比特币。他在报道中说:“从纯实用角度来看,金融机构正在探索是否有需要储备比特币以备不时之需,例如他们成为高强度攻击的目标,而执法部门并不能迅速地提供帮助让他们业务短时间内恢复正常。”

他还提到,大公司现在开始担心,一场网络攻击不再只关乎信息安全问题,而是变成了广泛的、涉及股东和顾客信赖的问题。

Simon曾预测情势将十分严峻。他认为当智能装备互联时代完全到来之际,现存的IT安全系统将无法阻挡别人利用如此巨大的计算力。

“我们现在所面对的就是这些(黑客工具)武器化利用。问题牵扯面比公司预计地广得多。一旦达到兆兆位,任何保护措施皆无用。现存的安全系统无一能处理如此之多的信息涌流。”

据估计,目前物联网连接装置在70亿与190亿之间。保守估计5年内将会增长到500亿。恶意软件事故应对公司Plixer IT部主管Thomas Pore说,新形式的攻击索要赎金可能即将到来,(公司)宁愿付钱解决威胁,也不愿看到大范围顾客服务中断。

“针对服务提供商的一场大范围的线路中断,比如DoS(服务拒绝)也将影响到客户,(公司)就会快速支付赎金以避免意外的客户流失或者造成更大的经济影响。”

Several of London’s largest banks are?stocking up?on Bitcoin in order to pay off cyber criminals who threaten to bring down their critical IT systems, say IT experts. The banks are now coming to terms with the view that it is cheaper to pay off criminals than risk ferocious cyber attacks on a high scale.

According to a Guardian report, paying ransoms with Bitcoin seems the better way to go because even though senior police officers have been made aware of the practice, the police do not have the resources to deal with the significant growth in the number of cyber attacks.

Dr. Simon Moores, who is a former technology ambassador for the UK government and chair of the annual international e-Crime Congress, did not identify the banks buying up Bitcoins, but stated in the report:

“From a purely pragmatic perspective, financial institutions are now exploring the need to maintain stocks of Bitcoin in the unfortunate event that they themselves become the target of a high-intensity attack, when law enforcement perhaps might not be able to assist them at the speed with which they need to put themselves back in business.”

He added that big companies are now starting to worry that an attack is no longer an information security issue but a board, shareholder and customer confidence issue.

New model of ransom-based attacks

He predicted that the situation was becoming critical particularly as he believes that the rollout of connected smart devices will allow for the harnessing of devastating computer power that can no longer be repelled by existing IT security systems.

“What we are seeing is the weaponization of these [hacking] tools. It becomes a much broader issue than businesses ever anticipated. Once it goes above a terabit, that wipes out any protection. No current protection systems can deal with that sort of flood.”

It is estimated that there are between 7bn and 19bn devices connected to the IoT at the moment. Conservative predictions suggest an increase to up to 50bn within five years.

A new model of ransom-based attacks could be on the horizon, motivated to pay off threats for fear of infrastructure-wide customer outages, adds the director of IT at Plixer, a malware incident response company, Thomas Pore. He stated:

“An infrastructure outage, such as DoS [denial of service], against a service provider impacting both the provider and customers may prompt a quick ransom payoff to avoid unwanted customer attrition or larger financial impact.”
