Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Ransomware Demands Up By 43% So Far In 2021
The average demand for a digital extortion payment shot up in the first quarter of this year to $220,298, up 43% from the previous quarter. The median payment, too, jumped up 58% from $49,450 to $78,398. The majority of ransomware attacks in the first quarter also involved theft of corporate data, a continuation of a trend of ransomware actors increasingly relying on exfiltration and extortion demands. Seventy-seven percent of ransomware attacks included the threat to publish stolen data in the first quarter of this year, which is up 10%.

US Tech Pushes For Ransomware To Be Designated A National Security Threat
Big US tech companies and officials are urging governments to designate ransomware as a national security threat in a push to combat a hacking epidemic that has cost businesses tens of millions of dollars. Tech groups including Microsoft, Cisco and Amazon, cyber security companies such as FireEye and officials from the FBI and US Department of Justice have published a report calling for several measures to tackle the lucrative criminal enterprise.

Flubot Spyware Spreading Through Android Devices
Android mobile phone users across the U.K. and Europe are being targeted by text messages containing a particularly nasty piece of spyware called “Flubot”. The malware is delivered to targets through SMS texts and prompts them to install a “missed package delivery” app. Instead, it takes victims to a scam website where they download the “app” — which is just the spyware. Once installed, it then sets about gaining permissions, stealing banking information and credentials, lifting passwords stored on the device and squirreling away various pieces of personal information. It also sends out additional text messages to the infected device’s contact list, which allows it to “go viral” — like the flu.

Ransomware: Do Not Expect A Full Recovery, However Much You Pay
When it comes to all the various types of malware out there, none has ever dominated the headlines quite as much as ransomware. Sure, several individual malware outbreaks have turned into truly global stories over the years. The LoveBug mass-mailing virus of 2000 springs to mind, which blasted itself into hundreds of millions of mailboxes within a few days; so, does CodeRed in 2001, the truly fileless network worm that squeezed itself into a single network packet and spread worldwide literally within minutes.

61% Of Organisations Impacted By Ransomware In 2020
A full 79% of respondents indicated their companies had experienced a business disruption, financial loss or other setback in 2020 due to a lack of cyber preparedness. Respondents identified ransomware as the chief culprit behind these disruptions. Other insights include: 61% indicated they had been impacted by ransomware in 2020, a 20% increase over the number of companies reporting such disruption in last year’s report. Companies impacted by ransomware lost an average of six working days to system downtime, with 37% saying downtime lasted one week or more. 52% of ransomware victims paid threat actor ransom demands, but only 66% of those were able to recover their data. The remaining 34% never saw their data again, despite paying the ransom.

SolarWinds Campaign Even Wider Than First Thought
A new analysis of the SolarWinds breach suggests that the attacker infrastructure behind the campaign is far larger than first believed. The catastrophic SolarWinds security incident involved the compromise of the IT software vendor's network and later the deployment of malicious SolarWinds Orion updates to clients that contained a backdoor called Sunburst. Now researchers have now uncovered eighteen additional command-and-control servers used in the SolarWinds hacking campaign, indicating that the operation was broader in scope than previously known. The researchers found that this infrastructure was registered under varying names and at different times over several years to avoid establishing a traceable pattern.
Buying Cyber Insurance In 2021? Expect Greater Scrutiny, Higher Premiums
Organisations will face significant challenges in purchasing, renewing, and benefitting from cyber insurance policies this year as various factors drive the sector towards a stricter, more specialized position, global specialists in law, risk, and cyber security predict. These include the continued evolution and impact of cyber threats throughout 2020 and the early months of 2021, chiefly in the form of ransomware attacks and wide-ranging supply chain security issues.
Ransomware Is Growing At An Alarming Rate, Warns GCHQ Chief
The scale and severity of ransomware is growing at an alarming rate as cyber criminals look to exploit poor cyber security to maximise profit, the director of GCHQ has warned. Organisations and their employees have been forced to adapt to different ways of working over the past year, with many now even more reliant on remote services and online collaboration platforms. But cyber-criminal gangs also represent a major threat and Fleming warned that ransomware represents a cyber security danger for organisations of all kinds.
