Deception Derails Ransomware: WannaCry Analyzed by Attivo Labs

As ransomware attacks continue to claim hundreds of thousands of victims, organizations are scrambling to figure out if their current security tools can effectively stop, detect, and remediate large-scale ransomware attacks.

While the major WannaCry ransomware attack was stopped by an uncovered kill switch, experts fear a resurgence of new strains without such shortcomings. Now, more than ever, organizations across all industries need to strengthen their defenses against these aggressive and damaging attacks.

Attivo Networks Urges Organizations to Adopt New Technology Designed to Derail Ransomware Attacks

Attivo Networks challenged not only healthcare, but all industries to take immediate steps in the wake of Friday’s global ransomware attacks. “It’s not only the sheer magnitude of the attacks, but also that hackers are now crossing ethical boundaries,” says Tushar Kothari, CEO of Attivo Networks. “Friday’s attacks signify a change in ransomware attacks from holding files hostage to creating situations that impact human safety.”

Hackers Hit Dozens of Countries With a Stolen N.S.A. Tool

LONDON — Hackers using a tool stolen from the United States government conducted extensive cyberattacks on Friday that hit dozens of countries around the world, severely disrupting Britain’s public health system and wreaking havoc on computers elsewhere, including Russia.

Hospitals in Britain appeared to be the most severely affected by the attacks, which aimed to blackmail computer users by seizing their data. The attacks blocked doctors’ access to patient files and forced emergency rooms to divert people seeking urgent care.

Kaspersky Lab, a Russian cybersecurity firm, said it had recorded at least 45,000 attacks in as many as 74 countries.

This Android flaw is ‘used by most ransomware’. But Google won’t fix it until Android O

The two newest versions of Android are vulnerable to a permissions feature being exploited by ransomware and banking malware.

Security firm Check Point has examined Android’s permission model and discovered it contains an odd bug that has become a favorite tool for ransomware, adware, and banking trojans to hijack victims’ screens with phishing pages and extortion demands.

This problem stems from an extremely sensitive permission in Android 6.0 Marshmallow, the most widely used version of Android, called SYSTEM_ALERT_WINDOW. The permission allows an app to create windows that overlay all other apps.

Ransomware attacks around the world grow by 50%

Ransomware attacks on businesses around the world rose 50% last year, research into successful cyber-breaches shows.

Its popularity means malware is now responsible for 51% of all the incidents analysed in the annual Verizon data breach report.

This analyses almost 2,000 breaches to find out how firms were caught out by cyber-thieves.

It also found that measures taken by some firms after payment systems were targeted, stopped new breaches.

The Ransomware Dilemma: Pay Now or Pay Later

According to a new study by Trend Micro, there is a reason ransomware continues to dominate the security news cycle. The study found that new ransomware families increased a whopping 752% in 2016. The report adds that the availability of open source ransomware and ransomware as a service (RaaS) will continue to make it easier for cybercriminals to run turnkey ransomware attacks. While it may be a challenge to find the money for ransomware prevention, the old adage “you can pay me now or pay me later” certainly comes to mind here. If you can’t find the budget to protect against ransomware, you may ultimately still find yourself paying in the long run. The findings shared here, can be useful as supporting budget justification.

2017 Cyberthreat Defense Report

The first three installments of the Cyberthreat Defense Report (CDR) began the process of looking beyond major breaches and the never-ending evolution of cyberthreats to better understand what IT security teams are doing to defense against them. Let’s face it. We all know that ransomware ran rampant in 2016. More valuable to most IT security professionals than the intimate details of the next variant to emerge on the scene are the tactics and technologies other organizations are using to defend against it.

RSA Key Sessions for 2017

RSA 2017 is in full swing this week and there are a number of sessions that we are classifying as “must see”. We anticipate deception based detection technology to be covered both in formal meetings and information discussions during the conference. However, since our ThreatMatrix platform now addresses so many vertical markets (financial, healthcare, IoT, SCADA, retail and hospitality) as well as new problems around phishing, cloud security, ransomware, unified swift collaboration in cybersecurity incident response, and assistance through our partners that can help with threat hunting and remediation, we’ve included some of those. We’ve found some top talks for you but before you begin

Ransomware Attack on Texas Clinic Affects 33k, Some Patient Records Lost

A ransomware attack on Grand Prairie, Texas-based Rainbow Children’s Clinic in early August reportedly affected 33,638 patients, according to Information Management.

On Aug. 3, a hacker launched a ransomware attack on the clinic’s computer system, encrypting data on the clinic’s servers. Rainbow Children’s Clinic attempted to quickly shut down its system, but an investigation conducted by a forensic expert proved a number of patient records had been deleted, reports Healthcare Finance News.

The potentially “irretrievably deleted” records may include patients’ names, addresses, dates of birth, Social Security numbers, medical information and payment guarantors.

London’s financial Center Bombarded With Ransomware

People who work in the City of London, the UK capital’s financial centre, are being targeted by a specific kind of computer attack that holds digital files to ransom.

Cybersecurity company Malwarebytes says that the City of London is a hotbed for ransomware attacks compared to the rest of Europe.

The company monitored cybersecurity threats for just over a year to see which parts of Europe had the most attacks. It found that the City of London suffered 10,500 ransomware attacks, which is 670% more than the second-biggest target, Manchester.
