Cisco Warns of ‘Destruction of Service’ Attacks

Networking company Cisco has uncovered the rapid evolution of threats and the increasing magnitude of attacks and forecasts potential “destruction of service” (DeOS) attacks.

In its 2017 Mid-year Cyber security Report, Cisco says these DeOS attacks could eliminate organisations’ backups and safety nets required to restore systems and data after an attack.

The report provides data-driven industry insights and cyber security trends from the first half of the year, along with actionable recommendations to improve security posture.

It is based on data from a vast footprint, amounting to a daily ingest of over 40 billion points of telemetry.

According to Cisco, with the advent of the Internet of things (IOT), key industries are bringing more operations online, increasing attack surfaces and the potential scale and impact of these threats.

It notes recent cyber incidents such as WannaCry and Nyetya show the rapid spread and wide impact of attacks that look like traditional ransomware, but are much more destructive.

These events foreshadow what Cisco is calling destruction of service attacks, which can be far more damaging, leaving businesses with no way to recover, the networking company says.

It adds that IOT continues to offer new opportunities for cyber criminals, and its security weaknesses, ripe for exploitation, will play a central role in enabling these campaigns with escalating impact.

Cisco believes recent IOT botnet activity already suggests some attackers may be laying the foundation for a wide-reaching, high-impact cyber threat event that could potentially disrupt the Internet.

“As recent incidents like WannaCry and Nyetya illustrate, our adversaries are becoming more and more creative in how they architect their attacks,” says Steve Martino, vice-president and chief information security officer at Cisco.

“While the majority of organisations took steps to improve security following a breach, businesses across industries are in a constant race against the attackers. Security effectiveness starts with closing the obvious gaps and making security a business priority.”

Microsoft Servers Hacked by Chinese Groups

Chinese “threat actors” have hacked Microsoft’s SharePoint document software servers and targeted the data of the businesses using it, the firm has said.

Microsoft Servers Hacked by Chinese Groups

 

China state-backed Linen Typhoon and Violet Typhoon as well as China-based Storm-2603 were said to have “exploited vulnerabilities” in on-premises SharePoint servers, the kind used by firms, but not in its cloud-based service.

The US tech giant has released security updates in response and has advised all on-premises SharePoint server customers to install them.

“Investigations into other actors also using these exploits are still ongoing,” Microsoft said in a statement.

The firm said it had “high confidence” the hackers would continue to target systems which have not installed its security updates.

It added that it would update its website blog with more information as its investigation continues.

Microsoft said it had observed attacks in which hackers had sent a request to a SharePoint server “enabling the theft of the key material by threat actors”.

Charles Carmakal, chief technology officer at Mandiant Consulting firm, a division of Google Cloud, told reporter, it was “aware of several victims in several different sectors across a number of global geographies”.

Carmakal said it appeared that governments and businesses that use SharePoint on their sites were the primary target.

A number of adversaries who stole material encoded by cryptography were then able to regain ongoing access to the victims’ SharePoint data, he said.

“This was exploited in a very broad way, very opportunistically before a patch was made available. That’s why this is significant,” Carmakal said.

Carmakal said the “China-nexus actor” was deploying techniques similar to previous campaigns associated with Beijing.

Microsoft said Linen Typhoon had “focused on stealing intellectual property, primarily targeting organizations related to government, defence, strategic planning, and human rights” for 13 years.

It added that Violet Typhoon had been “dedicated to espionage”, primarily targeting former government and military staff, non-governmental organizations, think tanks, higher education, the media, the financial sector and the health sector in the US, Europe, and East Asia.

Meanwhile, Storm-2603 was “assessed with medium confidence to be a China-based threat actor”.
