If your computer has been infected with PyLocky Ransomware and you are searching for a free ransomware decryption tool to unlock or decrypt your files—your search might end here. Security researcher Mike Bautista at Cisco's Talos cyber intelligence unit have released a free decryption tool that makes it possible for victims infected with the PyLocky ransomware to unlock their encrypted files for free without paying any ransom. The decryption tool works for everyone, but it has a huge limitation—to successfully recover your files, you must have captured the initial network traffic (PCAP file) between the PyLocky ransomware and its command-and-control (C2) server, which generally nobody purposely does. This is because the outbound connection—when the ransomware communicates with its C2 server and submit decryption key related information—contains a string that includes both Initialization Vector (IV) and a password, which the ransomware generates randomly to encrypt the file...

Cybersecurity researcher has discovered online a massive database containing records of more than 202 million Chinese citizens that remained accessible to anyone on the Internet without authentication until last week. The unprotected 854.8 gigabytes of the database was stored in an instance of MongoDB, a NoSQL high performance and cross-platform document-oriented database, hosted by an American server hosting company. In total, the database contained 202,730,434 records about job candidates from China, including candidates' personal information such as their full name, date of birth, phone number, email address, marriage status, and driver's license information, along with their professional experience and job expectations. Bob Diachenko, director of cyber risk research at Hacken.io and bug bounty platform HackenProof, discovered the existence of database two weeks ago, which had been secured shortly after his notification on Twitter. However, it is worth noting that ...

Security researchers have discovered three vulnerabilities in Systemd, a popular init system and service manager for most Linux operating systems, that could allow unprivileged local attackers or malicious programs to gain root access on the targeted systems. The vulnerabilities, assigned as CVE-2018-16864, CVE-2018-16865, and CVE-2018-16866, actually resides in the "systemd-journald" service that collects information from different sources and creates event logs by logging information in the journal. The vulnerabilities, which were discovered and reported by security researchers at Qualys, affect all systemd-based Linux distributions, including Redhat and Debian , according to the researchers. However, some Linux distros such as SUSE Linux Enterprise 15, openSUSE Leap 15.0, and Fedora 28 and 29 are not affected, as "their userspace [code] is compiled with GCC's -fstack-clash-protection ." The first two flaws are memory corruptions issues, while the ...

Security researchers have been warning about a simple technique that cybercriminals and email scammers are already being using in the wild to bypass security features of Microsoft Office 365, including Safe Links, which are originally designed to protect users from malware and phishing attacks. Safe Links has been included by Microsoft in Office 365 as part of its ATP (Advanced Threat Protection) solution that works by replacing all URLs in an incoming email with Microsoft-owned secure URLs. Therefore, every time users click on a link provided in an email, Safe Links first sends them to a Microsoft owned domain, where it immediately checks the original link for anything suspicious. If Microsoft's security scanners detect any malicious element, it then warns the users about it, and if not, it redirects them to the original link. However, researchers at the cloud security company Avanan have revealed how attackers have been bypassing both Office 365's URL reputation check a...

Almost every activity on the Internet starts with a DNS query, a key function of the Internet that works as an Internet's directory where your device looks up for the server IP addresses after you enter a human-readable web address (e.g., thehackernews.com). Since DNS queries are sent in clear text over UDP or TCP without encryption, the information can reveal not only what websites an individual visits but is also vulnerable to spoofing attacks. To address these problems, Google announced Wednesday that its Public DNS (Domain Name System) service finally supports DNS-over-TLS security protocol, which means that the DNS queries and responses will be communicated over TLS-encrypted TCP connections. The DNS-over-TLS has been designed to make it harder for man-in-the-middle attackers to manipulate the DNS query or eavesdrop on your Internet connection. Launched over eight years ago, Google Public DNS, at IP addresses 8.8.8.8 and 8.8.4.4, is world's largest public Domai...

Remember " The Shadow Brokers " and the arrest of a former NSA contractor accused of stealing 50 Terabytes of top secret documents from the intelligence agency? It turns out that, Kaspersky Lab, which has been banned in US government computers over spying fears, was the one who tipped off the U.S. government and helped the FBI catch NSA contractor Harold T. Martin III , unnamed sources familiar with the investigation told Politico. In October 2016, the U.S. government arrested and charged Martin, 51, with theft of highly classified documents, including most sensitive NSA hacking tools and top-secret information about "national defense," that he siphoned from government computers over the period of two decades. The breach is believed to be the largest heist of classified government material in America's history, far bigger than Edward Snowden leaks . According to the sources, the Antivirus firm learned about Martin after he sent unusual direct messag...

German police are seeking your help in gathering information related to a MAC address that could lead to the cell phone device used by a DHL blackmailer who last year parceled out bombs at different addresses in Brandenburg and Berlin. Between November 2017 and April 2018, someone used German parcel delivery service DHL to sent out several so-called improvised explosive devices (IEDs) in packets, demanding €10 million worth of bitcoins from the parcel service. In one event, a parcel containing nails, screws, and fireworks explosive powder was received by a pharmacy adjacent to the German Christmas market during 2017 Christmas, which eventually caused the evacuation of the market. German police later discovered a message inside that package in which the blackmailer threatened to send more parcels in the pre-Christmas season unless DHL made a 10 million euro payment in Bitcoin. During the investigation, the German police successfully communicated with the alleged blackmailer m...

Google has removed 85 apps from its Play Store after finding out that they were pushing aggressive, full-screen adware to Android users. With the rise in the mobile market, Adware has become one of the most prevalent mobile threats in the world. Adware has traditionally been used to aggressively push ads like banners or pop-ups on mobile screens to make money for its makers. The now-removed 85 apps in question disguised as games, streaming TV, and remote control simulator apps in the Google Play store and had collectively been installed by nine million users all over the world. Researchers from cyber security company Trend Micro spotted these apps which has the ability to bombard user devices with full-screen advertisements at regular intervals or when users unlock their device by monitoring their screen unlocking functionality. The apps can display ads even when you are not browsing the internet, hide themselves and run in the background on infected devices. The most popul...

Microsoft has issued its first Patch Tuesday for this year to address 49 CVE-listed security vulnerabilities in its Windows operating systems and other products, 7 of which are rated critical, 40 important and 2 moderate in severity.
