Top Cyber Stories of the Last Week

Insurers Run From Ransomware Cover As Losses Mount

Insurers have halved the amount of cyber cover they provide to customers after the pandemic and home-working drove a surge in ransomware attacks that left them smarting from hefty payouts.

Faced with increased demand, major European and US insurers and syndicates operating in the Lloyd's of London market have been able to charge higher premium rates to cover ransoms, the repair of hacked networks, business interruption losses and even PR fees to mend reputational damage.

But the increase in ransomware attacks and the growing sophistication of attackers have made insurers wary. Insurers say some attackers may even check whether potential victims have policies that would make them more likely to pay out.

"Insurers are changing their appetites, limits, coverage and pricing," Caspar Stops, head of cyber at insurance firm Optio, said. "Limits have halved – where people were offering 10 million pounds ($13.50 million), nearly everyone has reduced to five."

Lloyd's of London, which has around a fifth of the global cyber market, has discouraged its 100-odd syndicate members from taking on cyber business next year, industry sources say on condition of anonymity. Lloyd's declined to comment.

The Ransomware Threat Is Getting Worse. But Businesses Still Aren't Taking It Seriously

Ransomware is the most significant cybersecurity threat facing the country today, but many businesses still aren't taking the threat as seriously as they should be, the National Cyber Security Centre (NCSC) has warned.

In its newly published annual review, the NCSC – the cybersecurity arm of intelligence agency GCHQ – details the incidents and threats the UK has faced during the past 12 months, including cyberattacks against the health service and vaccine developers during the coronavirus pandemic, state-sponsored cyber-espionage campaigns, phishing scams and more.

But, because of the likely impact a successful attack could have on essential services or critical national infrastructure, it's ransomware that is viewed as the most dangerous cyber threat – and one that more leadership teams need to think about.

Ransomware Is Now A Giant Black Hole That Is Sucking In All Other Forms Of Cyber Crime

File-encrypting malware is where the money is -- and that's changing the whole online crime ecosystem.

Ransomware is so lucrative for the gangs involved that other parts of the cybercrime ecosystem are being repurposed into a system for delivering potential victims.

"The gravitational force of ransomware's black hole is pulling in other cyberthreats to form one massive, interconnected ransomware delivery system -- with significant implications for IT security," said security company Sophos in a report.

Ransomware is considered by many experts to be most pressing security risk facing businesses -- and its extremely lucrative for the gangs involved, with ransom payouts increasing significantly.

52% Of SMBs Have Experienced A Cyber Attack In The Last Year

The consequences of a breach have never been more severe, with global cybercrime collectively totalling $16.4 billion each day, a Devolutions survey reveals.

A recent study by IBM revealed that organizations with fewer than 500 employees had an average data breach cost of $2.98 million per incident in 2021. As has been reported, approximately 60% of SMBs go out of business within six months of getting hacked.

Smaller companies are not exempt from cyberattacks; in fact, it’s quite the opposite. Yet many of the tools and resources that larger companies have at their disposal to protect them from cyber attacks are not befitting for smaller companies. There is a gap in the market.

Ransomware Phishing Emails Sneak Through SEGs

Secure email gateway (SEG) protections aren’t necessarily enough to stop phishing emails from delivering ransomware to employees, especially if the cybercrooks are using legitimate cloud services to host malicious pages.

Researchers are raising the alarm over a phishing email kicking off a Halloween-themed MICROP ransomware offensive, which they observed making its way to a target’s inbox despite its being secured by an SEG.

Reality Check: Your Security Hygiene Is Worse Than You Think It Is

Sevco Security published a report which explores the gap between perceptions and realities of security hygiene and asset management. Leveraging findings from ESG’s “Security Hygiene and Posture Management Survey,” Sevco’s report addresses five unfounded perceptions that many security teams assume to be true and the realities that unveil alarming security risks.

The report reveals that the perception of good security hygiene often leads to gaps in asset inventory that leave organizations open to security incidents. One such gap is the assumption that organizations have an accurate understanding of asset inventory. The reality is that on average, organizations discover 20-30% previously unknown devices once various inventory sources have been analysed and reconciled.

The Covid-19 Crisis Has Fueled The Increase Of Cyber Crime In All Its Forms

The accelerated digitalization related to the COVID-19 pandemic has significantly influenced the development of a number of cyber threats, according to the new edition of Europol’s Internet Organised Crime Threat Assessment.

Criminals have been quick to abuse the current circumstances to increase profits, spreading their tentacles to various areas and exposing vulnerabilities, connected to systems, hospitals or individuals.

While ransomware groups have taken advantage of widespread teleworking, scammers have abused COVID-19 fears and the fruitless search for cures online to defraud victims or gain access to their bank accounts. The increase of online shopping in general has attracted more fraudsters. With children spending a lot more time online, especially during lockdowns, grooming and dissemination of self-produced explicit material have increased significantly.

Ransomware Attacks Are Getting More Complex And Even Harder To Prevent

Ransomware attackers are probing known common vulnerabilities and exposures (CVEs) for weaknesses and quickly capitalizing on them, launching attacks faster than vendor teams can patch them. Unfortunately, ransomware attackers are also making attacks more complex, costly, and challenging to identify and stop, acting on potential targets’ weaknesses faster than enterprises can react.

Two recent research studies — Ivanti’s latest ransomware report, conducted with Cyber Security Works and Cyware, and a second study by Forrester Consulting on behalf of Cyware — show there’s a widening gap between how quickly enterprises can identify a ransomware threat versus the quickness of a cyberattack. Both studies provide a stark assessment of how far behind enterprises are on identifying and stopping ransomware attacks.

Most Ransomware Attacks Rely On Exploiting Older, Unpatched Vulnerabilities

Ransomware attackers exploited a dozen new vulnerabilities in campaigns in Q3 2021, bringing the total number of vulnerabilities associated with ransomware to 278, claims a new report.

Compiled by cybersecurity vendor Ivanti, the report reveals that ransomware groups are continuing to grow in sophistication, boldness, and volume, with numbers up across the board since Q2 2021.

It tracked a 4.5% increase in CVEs associated with ransomware in Q3 2021, along with a similar increase in actively exploited and trending vulnerabilities, along with a 3.4% increase in ransomware families, as compared to Q2 2021.

Out-Of-Hours Ransomware Attacks Have A Greater Impact On Revenue

Ransomware attacks at weekends and holidays are throwing victims into disarray, according to a study released by security company Cybereason.

The report, “Organizations at Risk: Ransomware Attackers Don’t Take Holidays,” surveyed security professionals whose organizations suffered a ransomware attack during a holiday or weekend in the last 12 months. It found 86% of them reported missing holiday or weekend activities with friends and family when responding to these attacks.

Of those surveyed, 60% take longer to assess the scope of an attack that happened over the weekend or on a holiday. Half said out-of-hours attacks led to a slower response overall.

One problem was assembling the right team, with just over a third reporting difficulties in getting the necessary people together. When those people do clock in unexpectedly, they might not be fully fit for duty. In fact, 70% were intoxicated when called in to address the attack, the report added.
