Microsoft: Chinese Cyberspies Used 4 Exchange Server Flaws to Plunder Emails (Krebs on Security)

Sécurité

Microsoft Corp. today released software updates to plug four security holes that attackers have been using to plunder email communications at companies that use its Exchange Server products. The company says all four flaws are being actively exploited as part of a complex attack chain deployed by a previously unidentified Chinese cyber espionage group. The software giant typically releases security updates on the second Tuesday of each month, but it occasionally deviates from that schedule when addressing active attacks that target newly identified and serious vulnerabilities in its products. The patches released today fix security problems in Microsoft Exchange Server 2013, 2016 and 2019. Microsoft said its Exchange Online service — basically hosted email for businesses — is not impacted by these flaws. Microsoft credited researchers at Reston, Va. based…

Payroll/HR Giant PrismHR Hit by Ransomware? (Krebs on Security)

Sécurité

PrismHR, a company that sells technology used by other firms to help more than 80,000 small businesses manage payroll, benefits, and human resources, has suffered what appears to be an ongoing ransomware attack that is disrupting many of its services. Hopkinton, Mass.-based PrismHR handles everything from payroll processing and human resources to health insurance and tax forms for hundreds of “professional employer organizations” (PEOs) that serve more than two million employees. The company processes more than $80 billion payroll payments annually on behalf of PEOs and their clients. Countless small businesses turn to PEOs in part because they simplify compliance with various state payroll taxes, and because PEOs are the easiest way for small businesses to pool their resources and obtain more favorable health insurance rates for their employees. PrismHR…

Is Your Browser Extension a Botnet Backdoor? (Krebs on Security)

Sécurité

A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations. This story examines the lopsided economics of extension development, and why installing an extension can be such a risky proposition. Singapore-based Infatica[.]io is part of a growing industry of shadowy firms trying to woo developers who maintain popular browser extensions — desktop and mobile device software add-ons available for download from Apple, Google, Microsoft and Mozilla designed to add functionality or customization to one’s browsing experience. Some of these extensions have garnered hundreds of thousands or even millions of users. But here’s the rub: As an extension’s user base grows, maintaining…

Celebrating the influence and contributions of Black+ Security & Privacy Googlers (Google Online Security Blog)

Sécurité

Posted by Royal Hansen, Vice President, SecurityBlack History Month may be coming to a close, but our work to build sustainable equity for Google’s Black+ community, and externally is ongoing. Currently, Black Americans make up less than 12% of information security analysts in the U.S. In an industry that consistently requires new ideas to spark positive change and stand out against the status quo, it is necessary to have individuals who think, speak, and act in diverse ways. Diverse security teams are more innovative, produce better products and enhance an organization's ability to defend against cyber threats.In an effort to amplify the contributions of the Black+ community to security and privacy fields, we’ll be sharing profiles of Black+ Googlers working on innovative privacy and security solutions over the coming weeks,…

How $100M in Jobless Claims Went to Inmates (Krebs on Security)

Sécurité

The U.S. Labor Department’s inspector general said this week that roughly $100 million in fraudulent unemployment insurance claims were paid in 2020 to criminals who are already in jail. That’s a tiny share of the estimated tens of billions of dollars in jobless benefits states have given to identity thieves in the past year. To help reverse that trend, many states are now turning to a little-known private company called ID.me. This post examines some of what that company is seeing in its efforts to stymie unemployment fraud. These prisoners tried to apply for jobless benefits. Personal information from the inmate IDs has been redacted. Image: ID.me A new report (PDF) from the Labor Department’s Office of Inspector General (OIG) found that from March through October of 2020, some $3.5…

Sécurité

Posted by Arvind Kumar Sugumar, Software Engineer, Android TeamWith the proliferation of digital services in our lives, it’s more important than ever to make sure our online information remains safe and secure. Passwords are usually the first line of defense against hackers, and with the number of data breaches that could publicly expose those passwords, users must be vigilant about safeguarding their credentials. To make this easier, Chrome introduced the Password Checkup feature in 2019, which notifies you when one of the passwords you’ve saved in Chrome is exposed. We’re now bringing this functionality to your Android apps through Autofill with Google. Whenever you fill or save credentials into an app, we’ll check those credentials against a list of known compromised credentials and alert you if your password has been…

Checkout Skimmers Powered by Chip Cards (Krebs on Security)

Sécurité

Easily the most sophisticated skimming devices made for hacking terminals at retail self-checkout lanes are a new breed of PIN pad overlay combined with a flexible, paper-thin device that fits inside the terminal’s chip reader slot. What enables these skimmers to be so slim? They draw their power from the low-voltage current that gets triggered when a chip-based card is inserted. As a result, they do not require external batteries, and can remain in operation indefinitely. A point-of-sale skimming device that consists of a PIN pad overlay (top) and a smart card skimmer (a.k.a. “shimmer”). The entire device folds onto itself, with the bottom end of the flexible card shimmer fed into the mouth of the chip card acceptance slot. The overlay skimming device pictured above consists of two main…

Smart cities : la prochaine étape des cybercriminels (JDN : Derniers contenus)

Actualités

Les innombrables avantages des villes intelligentes, à la fois durables et novatrices, reposent par définition sur une série d'appareils, de systèmes industriels, et d’objets interconnectés qui constituent dans leur ensemble une architecture IT complexe. Seulement, leur plus grande force, résidant dans leur capacité intrinsèque à s'interconnecter, peut également devenir leur plus grande faiblesse. Imaginons un instant l'ampleur des dommages que des cybercriminels pourraient causer dans une ville entièrement connectée, reposant sur l'interopérabilité des systèmes. Un seul capteur peut fournir un point d'entrée, constituant ainsi une brèche pour atteindre l’ensemble du système. Si l’un des appareils ne dispose pas d'une sécurité suffisante ou si son certificat a expiré (ce qui, avouons-le, peut encore arriver), l'ensemble de la structure devient vulnérable aux attaques. Cette dernière peut alors subir des pannes momentanées affectant…

2010-2020 : les attaques de ransomware sont devenues mortelles (JDN : Derniers contenus)

Actualités

Ces dix dernières années, les cyberattaques sont devenues une menace majeure pour les entreprises et leurs données, mais pour les entreprises de secteurs critiques comme l’énergie ou la santé, il est devenu évident que l'impact d'une cyberattaque dépasse maintenant la simple perte de données. Un temps mort dans ces secteurs peut vite devenir synonyme de pertes en vies humaines ou d’accidents graves. Après dix ans d’attaques et d’évolutions, les cybercriminels ciblent maintenant les systèmes essentiels des entreprises en sollicitant des paiements en échange d'une clé de décryptage. Pour maximiser leurs chances, ils s’attaquent aux systèmes essentiels pour maintenir les entreprises en activité. Les secteurs clés de notre économie ont donc dû considérablement étendre et adapter leurs protocoles de protection et de sécurisation des données. Pour faire face à ces défis,…
