5,183 breaches in first nine months of 2019 exposed 7.9b data records

As many as 7.9 billion data records were leaked, stolen or exposed as a result of 5,183 data breaches that took place in the first nine months of 2019, making it the worst year ever for data breaches.

This alarming statistic was revealed by security firm Risk Based Security which observed that based on recent trends, the number of breached data records could touch 8.5 billion by the end of the year.

The firm also noted that the total number of data breaches worldwide rose by 33.3 percent compared to the mid-year of 2018 and the number of records breached also rose by 112 percent. As many as 3.1 million data records were breached as a result of six data breach incidents that took place between 1 July and 30 September.

The majority of data records were exposed or leaked as a result of accidental exposure of data on the internet by organisations. The fact that hackers are quite willing to take advantage of such data exposure has also led to a rise in the number of breached records.

44 million Microsoft customers found using compromised passwords

Microsoft's identity threat researchers have revealed that 44 million of its users are still using passwords that have previously been compromised in past data breaches.

The 44 million weak accounts comprised both Microsoft Services Accounts (regular users) and Azure AD accounts too, suggesting businesses are not adopting proper password hygiene.

A total of three billion user credentials were checked in a database populated from numerous sources including law enforcement and public databases.

Using the data set of three billion credentials, Microsoft was able to identify the number of users who were reusing credentials across multiple online services.

Microsoft forced a password reset for all of those users who were found to have leaked credentials during the scan which took place between January and March 2019.

Evil Corp: US charges Russians over hacking attacks

US authorities have filed charges against two Russian nationals alleged to be running a global cyber crime organisation named Evil Corp.

An indictment named Maksim Yakubets and Igor Turashev - who remain at large - as figures in a group which used malware to steal millions of dollars in more than 40 countries.

Those affected by the hacks include schools and religious organisations. It is also alleged that Mr Yakubets worked for Russian intelligence.

The attacks are said to be amongst the worst computer hacking and bank fraud schemes of the past decade. The $5m reward being offered for information leading to their arrest and prosecution is the largest yet for catching cyber criminals.

Thursday's indictment came after a multi-year investigation by the US and British law enforcement agencies.

Authorities allege that the group stole at least $100m (£76m) using Bugat malware - known as Dridex.

The malware was spread through so-called "phishing" campaigns, which encouraged victims to click on malicious links sent by email from supposedly trusted entities.

Once a computer was infected, the group stole personal banking information which was used to transfer funds.

A network of money launderers - targeted by the NCA and Britain's Metropolitan Police - were then utilised to funnel the criminal proceeds to members of Evil Corp. Eight members of this network have been sentenced to a total of over 40 years in prison.

New ransomware attacks target your NAS devices, backup storage

New ransomware that targets Network Attached Storage devices and other backup devices has surged in recent months with many users unprepared for the increased level of threat.

As with all ransomware paying the ransom is no guarantee of getting data back and should only ever be an absolute last resort.

With networked and backup storage devices falling victim to ransomware infections that emphasises the need to ensure firms have offline copies of backups. Backups that are that are disconnected from systems cannot themselves be corrupted or fall victim to ransomware and would therefore be a firm’s best bet in being able to recover from such an attack.

New vulnerability lets attackers sniff or hijack VPN connections

Academics have disclosed this week a security flaw impacting Linux, Android, macOS, and other Unix-based operating systems that allows an attacker to sniff, hijack, and tamper with VPN-tunneled connections. OpenVPN, WireGuard, and IKEv2/IPSec VPNs are all vulnerable to attacks.

The vulnerability -- tracked as CVE-2019-14899 -- resides in the networking stacks of multiple Unix-based operating systems, and more specifically, in how the operating systems reply to unexpected network packet probes.

According to the research team, attackers can use this vulnerability to probe devices and discover various details about the user's VPN connection status.

Whilst this vulnerability affects Linux, Android, Mac and other Unix-based operating systems this vulnerability is not currently believed to affect Windows based systems.

Newly discovered Mac malware uses “fileless” technique to remain stealthy

Hackers believed to be working for the North Korean government have upped their game with a recently discovered Mac trojan that uses in-memory execution to remain stealthy.

In-memory execution, also known as fileless infection, never writes anything to a computer hard drive. Instead, it loads malicious code directly into memory and executes it from there. The technique is an effective way to evade antivirus protection because there’s no file to be analyzed or flagged as suspicious.

In-memory infections were once the sole province of state-sponsored attackers. By 2017, more advanced financially motivated hackers had adopted the technique. It has become increasingly common since then.

Europol seizes more than 30,000 counterfeit sites on Cyber Monday

Europol has taken down more than 30,000 different web domains which allowed cyber criminals to sell counterfeit and pirated items online.

The joint operation between 18 member states and the US National Intellectual Property Rights Coordination Centre, with help Eurojust and INTERPOL, included the seizure of articles such as fake medicines, pirated movies, music, software and counterfeit electronics.

In addition, officials identified and froze more than €150 000 (£128,000) in several bank accounts and online payment platforms.

As a result of the coordinated operation, codenamed IOS X (In Our Sites), three arrests have been made and 26,000 "luxury products" have been seized along with the swathe of illicit websites.

The IOS campaign launched in 2014, one that Europol has gained in strength year-on-year, and aims to "make the internet a safer place for consumers by recruiting more countries and private sector partners to participate in the operation and providing referrals".
