Dixons Carphone's 2017 data breach was worse than initially anticipated. In an announcement on Monday, Dixons Carphone, one of the largest consumer electronics and telecommunication retailers in Europe, admitted that the breach affected around 10 million customers, up from an initial estimate of 1.2 million people the company acknowledged back in June. The company, which has been investigating the hack since it was discovered in June this year, said the investigation is nearly over and now there is evidence that some of the data may have been taken from its systems. The Carphone Warehouse and Currys PC World owner said the hackers may have accessed personal information of its affected customers including their names, addresses and email addresses last year. The hackers also got access to 5.9 million payments cards used at Currys PC World and Dixons Travel, but nearly all of those cards were protected by the chip-and-pin system . However, Dixons Carphone assured its cust

Another day, Another data breach! This time-sensitive and personal data of hundreds of thousands of people at Boys Town National Research Hospital have been exposed in what appears to be the largest ever reported breach by a pediatric care provider or children's hospital. According to the U.S. Department of Health and Human Services Office for Civil Rights, the breach incident affected 105,309 individuals , including patients and employees, at the Omaha-based medical organization. In a "Notice of Data Security Incident" published on its website, the Boys Town National Research Hospital admitted that the organization became aware of an abnormal behavior regarding one of its employees' email account on May 23, 2018. After launching a forensic investigation, the hospital found that an unknown hacker managed to infiltrate into the employee's email account and stole personal information stored within the email account as a result of unauthorized access. T

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Singapore's largest healthcare group, SingHealth, has suffered a massive data breach that allowed hackers to snatch personal information on 1.5 million patients who visited SingHealth clinics between May 2015 and July 2018. SingHealth is the largest healthcare group in Singapore with 2 tertiary hospitals, 5 national specialty , and eight polyclinics. According to an advisory released by Singapore's Ministry of Health (MOH), along with the personal data, hackers also managed to stole 'information on the outpatient dispensed medicines' of about 160,000 patients, including Singapore's Prime Minister Lee Hsien Loong, and few ministers. "On 4 July 2018, IHiS' database administrators detected unusual activity on one of SingHealth's IT databases. They acted immediately to halt the activity," MOH said. The stolen data includes the patient's name, address, gender, race, date of birth, and National Registration Identity Card (NRIC) numbers. Th

Microsoft said it detected and helped the US government to block Russian hacking attempts against at least three congressional candidates this year, a Microsoft executive revealed speaking at the Aspen Security Forum today. Although the company refused to name the targets but said, the three candidates were "people who, because of their positions, might have been interesting targets from an espionage standpoint as well as an election disruption standpoint." According to the company, the Russian hackers targeted the candidates' staffers with phishing attacks, redirecting them to a fake Microsoft website, in an attempt to steal their credentials. "Earlier this year, we did discover that a fake Microsoft domain had been established as the landing page for phishing attacks," said Tom Burt, Microsoft's vice president for customer security. "And we saw metadata that suggested those phishing attacks were being directed at three candidates who are all sta

In a legal extradition tug-of-war between the United States and Russia, it seems France has won the game, surprisingly. A Greek court has ruled to extradite the Russian cybercrime suspect and the former operator of now-defunct BTC-e crypto exchange to France, instead of the United States or to his native Russia, according to multiple Russian news outlets. Alexander Vinnik , 38, has been accused of laundering more than $4 billion in bitcoin for criminals involved in hacking attacks, tax fraud and drug trafficking with the help of BTC-e crypto exchange. BTC-e, a digital currency exchange service operating since 2011, was seized by the authorities right after Vinnik's arrest in northern Greece in late July 2016 at the request of US law enforcement authorities. Vinnik is also accused to the failure of the once-most famous Japanese bitcoin exchange Mt. Gox , which was shut down in 2014 following a series of mysterious robberies, which totaled at least $375 million in Bitcoin

A 21-year-old New Jersey woman has been charged with hacking into the email accounts of pop star and actress Selena Gomez, stealing her personal photos, and then leaked them to the Internet. Susan Atrach of Ridgefield Park was charged Thursday with 11 felony counts—five counts of identity theft, five counts of accessing and using computer data to commit fraud or illegally obtain money, property or data, and one count of accessing computer data without permission. According to the prosecutors, Atrach allegedly hacked into email accounts belonging to Gomez and one of her associates several times between June 2015 and February 2016, the Los Angeles County District Attorney's office said in a press release . She then obtained images and other media stored there and shared them with her friends and posted them online. Gomez, who has more than 138 million followers on Instagram, was the victim of a hacking attack in August 2017, when photographs of her ex-boyfriend Justin Bieb

The US Justice Department has announced criminal indictments against 12 Russian intelligence officers tied to the hack of the Democratic National Committee (DNC) during the 2016 US presidential election campaign. The charges were drawn up as part of the investigation of Russian interference in the 2016 US presidential election by Robert Mueller, the Special Counsel, and former FBI director. The indictments against 12 Russian military officers were announced by Deputy Attorney General Rod Rosenstein during a DoJ press conference on Friday—just 3 days before the Russian leader Vladimir Putin is scheduled to meet with President Donald Trump. All 12 Russian officers are members of the country's GRU military intelligence unit and are accused of carrying out "large-scale cyber operations" to hack into DNC network and steal Democrats' emails to influence the 2016 presidential election. Here's the list of all 12 defendants: Viktor Borisovich Netyksho Boris

It's time to gear up your systems and software for the latest July 2018 Microsoft security patch updates. Microsoft today released security patch updates for 53 vulnerabilities, affecting Windows, Internet Explorer (IE), Edge, ChakraCore, .NET Framework, ASP.NET, PowerShell, Visual Studio, and Microsoft Office and Office Services, and Adobe Flash Player. Out of 53 vulnerabilities, 17 are rated critical, 34 important, one moderate and one as low in severity. This month there is no critical vulnerability patched in Microsoft Windows operating system and surprisingly, none of the flaw patched by the tech giant this month is listed as publicly known or under active attack. Critical Flaws Patched In Microsoft Products Most of the critical issues are memory corruption flaws in IE, Edge browser and Chakra scripting engine, which if successfully exploited, could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system in the context of the cur

Security researchers from Check Point Threat Intelligence Team have discovered the comeback of an APT (advanced persistent threat) surveillance group targeting institutions across the Middle East, specifically the Palestinian Authority. The attack, dubbed "Big Bang," begins with a phishing email sent to targeted victims that includes an attachment of a self-extracting archive containing two files—a Word document and a malicious executable. Posing to be from the Palestinian Political and National Guidance Commission, the Word document serves as a decoy to distract victims while the malware is installed in the background. The malicious executable, which runs in the background, act as the first stage info-stealer malware designed for intelligence gathering to identify potential victims (on the basis of what is unclear as of now), and then it accordingly downloads the second stage malware designed for espionage. "While the analysis...discloses the capabilities of

Digitally signed malware has become much more common in recent years to mask malicious intentions. Security researchers have discovered a new malware campaign misusing stolen valid digital certificates from Taiwanese tech-companies, including D-Link, to sign their malware and making them look like legitimate applications. As you may know, digital certificates issued by a trusted certificate authority (CA) are used to cryptographically sign computer applications and software and are trusted by your computer for execution of those programs without any warning messages. However, malware author and hackers who are always in search of advanced techniques to bypass security solutions have seen been abusing trusted digital certificates in recent years. Hackers use compromised code signing certificates associated with trusted software vendors in order to sign their malicious code, reducing the possibility of their malware being detected on targeted enterprise networks and consumer

Hacker himself got hacked. It turns out that most samples of the LokiBot malware being distributed in the wild are modified versions of the original sample, a security researcher has learned. Targeting users since 2015, LokiBot is a password and cryptocoin-wallet stealer that can harvest credentials from a variety of popular web browsers, FTP, poker and email clients, as well as IT administration tools such as PuTTY. The original LokiBot malware was developed and sold by online alias "lokistov," a.k.a. "Carter," on multiple underground hacking forums for up to $300, but later some other hackers on the dark web also started selling same malware for a lesser price (as low as $80). It was believed that the source code for LokiBot was leaked which might have allowed others to compile their own versions of the stealer. However, a researcher who goes by alias " d00rt " on Twitter found that someone made little changes (patching) in the original Lok

Security researchers have discovered an interesting piece of malware that infects systems with either a cryptocurrency miner or ransomware, depending upon their configurations to decide which of the two schemes could be more profitable. While ransomware is a type of malware that locks your computer and prevents you from accessing the encrypted data until you pay a ransom to get the decryption key required to decrypt your files, cryptocurrency miners utilize infected system's CPU power to mine digital currencies . Both ransomware and cryptocurrency mining-based attacks have been the top threats so far this year and share many similarities such as both are non-sophisticated attacks, carried out for money against non-targeted users, and involve digital currency. However, since locking a computer for ransom doesn't always guarantee a payback in case victims have nothing essential to losing, in past months cybercriminals have shifted more towards fraudulent cryptocurrency

Maintainers of the Gentoo Linux distribution have now revealed the impact and "root cause" of the attack that saw unknown hackers taking control of its GitHub account last week and modifying the content of its repositories and pages. The hackers not only managed to change the content in compromised repositories but also locked out Gentoo developers from their GitHub organisation. As a result of the incident, the developers were unable to use GitHub for five days. What Went Wrong? Gentoo developers have revealed that the attackers were able to gain administrative privileges for its Github account, after guessing the account password. The organisation could have been saved if it was using a two-factor authentication, which requires an additional passcode besides the password in order to gain access to the account. "The attacker gained access to a password of an organization administrator. Evidence collected suggests a password scheme where disclosure on on

Global entertainment ticketing service Ticketmaster has admitted that the company has suffered a security breach, warning customers that their personal and payment information may have been accessed by an unknown third-party. The company has blamed a third-party support customer service chat application for the data breach that believed to affect tens of thousands of its customers. The customer support chat application, made by Inbenta Technologies—a third-party artificial intelligence tech supplier—used to help major websites interact with their customers. In its statement , Ticketmaster said it discovered malicious software on the customer support application hosted on its UK website that allowed attackers to extract the personal and payment information from its customers buying tickets. Ticketmaster disabled the Inbenta product across all of its websites as soon as it recognized the malicious code. However, Inbenta Technologies turned away blame back to Ticketmaster, sa

Security researchers have uncovered a new highly-targeted cyber espionage campaign, which is believed to be associated with a hacking group behind KHRAT backdoor Trojan and has been targeting organizations in South East Asia. According to researchers from Palo Alto , the hacking group, which they dubbed RANCOR, has been found using two new malware families—PLAINTEE and DDKONG—to target political entities primarily in Singapore and Cambodia. However, in previous years, threat actors behind KHRAT Trojan were allegedly linked to a Chinese cyber espionage group, known as DragonOK. While monitoring the C&C infrastructure associated with KHRAT trojan, researchers identified multiple variants of these two malware families, where PLAINTEE appears to be the latest weapon in the group's arsenal that uses a custom UDP protocol to communicate with its remote command-and-control server. To deliver both PLAINTEE and DDKONG, attackers use spear phishing messages with different inf

Security-oriented BSD operating system OpenBSD has decided to disable support for Intel's hyper-threading performance-boosting feature, citing security concerns over Spectre-style timing attacks . Introduced in 2002, Hyper-threading is Intel's implementation of Simultaneous Multi-Threading (SMT) that allows the operating system to use a virtual core for each physical core present in processors in order to improve performance. The Hyper-threading feature comes enabled on computers by default for performance boosting, but in a detailed post published Tuesday, OpenBSD maintainer Mark Kettenis said such processor implementations could lead to Spectre-style timing attacks. "SMT (Simultaneous multithreading) implementations typically share TLBs and L1 caches between threads," Kettenis wrote. "This can make cache timing attacks a lot easier, and we strongly suspect that this will make several Spectre-class bugs exploitable." In cryptography, side-channe

Security researchers have been warning about a simple technique that cyber criminals and email scammers are using in the wild to bypass most AI-powered phishing detection mechanisms implemented by widely used email services and web security scanners. Dubbed ZeroFont , the technique involves inserting hidden words with a font size of zero within the actual content of a phishing email, keeping its visual appearance same, but at the same time, making it non-malicious in the eyes of email security scanners. According to cloud security company Avanan , Microsoft Office 365 also fails to detect such emails as malicious crafted using ZeroFont technique. Like Microsoft Office 365, many emails and web security services use natural language processing and other artificial intelligence-based machine learning techniques to identify malicious or phishing emails faster. The technology helps security companies to analyze, understand and derive meaning from unstructured text embedded in an

Remember the ' Olympic Destroyer ' cyber attack? The group behind it is still alive, kicking and has now been found targeting biological and chemical threat prevention laboratories in Europe and Ukraine, and a few financial organisation in Russia. Earlier this year, an unknown group of notorious hackers targeted Winter Olympic Games 2018 , held in South Korea, using a destructive malware that purposely planted sophisticated false flags to trick researchers into mis-attributing the campaign. Unfortunately, the destructive malware was successful to some extent, at least for a next few days, as immediately after the attack various security researchers postmortem the Olympic Destroyer malware and started attributing the attack to different nation-state hacking groups from North Korea, Russia, and China. Later researchers from Russian antivirus vendor Kaspersky Labs uncovered more details about the attack, including the evidence of false attribution artifacts, and conclud

A 29-year-old former CIA computer programmer who was charged with possession of child pornography last year has now been charged with masterminding the largest leak of classified information in the agency's history. Joshua Adam Schulte , who once created malware for both the CIA and NSA to break into adversaries computers, was indicted Monday by the Department of Justice on 13 charges of allegedly stealing and transmitting thousands of classified CIA documents , software projects , and hacking utilities . Schulte has also been suspected of leaking the stolen archive of documents to anti-secrecy organization WikiLeaks, who then began publishing the classified information in March 2017 in a series of leaks under the name " Vault 7 ." It is yet unconfirmed whether Schulte leaked documents to WikiLeaks and if yes, then when, but he had already been a suspect since January 2017 of stealing classified national defense information from the CIA in 2016. According to

Cybersecurity researchers have uncovered an espionage campaign that has targeted a national data center of an unnamed central Asian country in order to conduct watering hole attacks. The campaign is believed to be active covertly since fall 2017 but was spotted in March by security researchers from Kaspersky Labs, who have attributed these attacks to a Chinese-speaking threat actor group called LuckyMouse . LuckyMouse, also known as Iron Tiger, EmissaryPanda, APT 27 and Threat Group-3390, is the same group of Chinese hackers who was found targeting Asian countries with Bitcoin mining malware early this year. The group has been active since at least 2010 and was behind many previous attack campaigns resulting in the theft of massive amounts of data from the directors and managers of US-based defense contractors. This time the group chose a national data center as its target from an unnamed country in Central Asia in an attempt to gain "access to a wide range of government
