New Attack Leverages HTTP/2 for Effective Remote Timing Side-Channel Leaks

New Attack Leverages HTTP/2 for Effective Remote Timing Side-Channel Leaks

Jul 31, 2020
Security researchers have outlined a new technique that renders a remote timing-based side-channel attack more effective regardless of the network congestion between the adversary and the target server. Remote timing attacks that work over a network connection are predominantly affected by variations in network transmission time (or jitter), which, in turn, depends on the load of the network connection at any given point in time. But since measuring the time taken to execute cryptographic algorithms is crucial to carrying out a timing attack and consequently leak information, the jitter on the network path from the attacker to the server can make it impractical to successfully exploit timing side-channels that rely on a small difference in execution time. The new method, called Timeless Timing Attacks (TTAs) by researchers from DistriNet Research Group and New York University Abu Dhabi, instead leverages multiplexing of network protocols and concurrent execution by applicati

Is Your Security Vendor Forcing You To Move to the Cloud? You Don't Have To!

Jul 29, 2020
Many endpoint security vendors are beginning to offer their applications only in the cloud, sunsetting their on-premise offerings. This approach may be beneficial to the vendor, but many clients continue to need on-premise solutions. Vendors that sunset on-premise solutions force clients that prefer on-premise solutions to either change their operating environment and approach or change vendors. Fortunately, some vendors continue to provide their offerings in both cloud and on-premise versions. One such company is Cynet , which allows clients to deploy their EDR and XDR (Extended Detection and Response) solutions in on-premise, cloud, and hybrid cloud delivery models. Clients can access the solution in any way they see fit now and into the future. This provides an alternative for organizations that do not want to be forced to move into the cloud. Cloud vs. On-Premise The cloud vs. on-premise argument continues to rage. Recently, however, it seems that everyone is jumpin

Researchers Reveal New Security Flaw Affecting China's DJI Drones

Researchers Reveal New Security Flaw Affecting China's DJI Drones

Jul 24, 2020
Cybersecurity researchers on Thursday revealed security issues in the Android app developed by Chinese drone-maker Da Jiang Innovations (DJI) that comes with an auto-update mechanism that bypasses Google Play Store and could be used to install malicious applications and transmit sensitive personal information to DJI's servers. The twin reports, courtesy of cybersecurity firms Synacktiv and GRIMM , found that DJI's Go 4 Android app not only asks for extensive permissions and collects personal data (IMSI, IMEI, the serial number of the SIM card), it makes use of anti-debug and encryption techniques to thwart security analysis. "This mechanism is very similar to command and control servers encountered with malware," Synacktiv said. "Given the wide permissions required by DJI GO 4 — contacts, microphone, camera, location, storage, change network connectivity — the DJI or Weibo Chinese servers have almost full control over the user's phone."

Chinese Hackers Escalate Attacks Against India and Hong Kong Amid Tensions

Jul 21, 2020
An emerging threat actor out of China has been traced to a new hacking campaign aimed at government agencies in India and residents of Hong Kong intending to steal sensitive information, cybersecurity firm Malwarebytes revealed in the latest report shared with The Hacker News. The attacks were observed during the first week of July, coinciding the passage of controversial security law in Hong Kong and India's ban of 59 China-made apps over privacy concerns, weeks after a violent skirmish along the Indo-China border. Attributing the attack with "moderate confidence" to a new Chinese APT group, Malwarebytes said they were able to track their activities based on the "unique phishing attempts" designed to compromise targets in India and Hong Kong. The operators of the APT group have leveraged at least three different Tactics, Techniques, and Procedures (TTPs), using spear-phishing emails to drop variants of Cobalt Strike and MgBot malware, and bogus Andr

Microsoft Releases Urgent Windows Update to Patch Two Critical Flaws

Microsoft Releases Urgent Windows Update to Patch Two Critical Flaws

Jul 01, 2020
Microsoft yesterday quietly released out-of-band software updates to patch two high-risk security vulnerabilities affecting hundreds of millions of Windows 10 and Server editions' users. To be noted, Microsoft rushed to deliver patches almost two weeks before the upcoming monthly 'Patch Tuesday Updates' scheduled for 14th July. That's likely because both flaws reside in the Windows Codecs Library , an easy attack vector to social engineer victims into running malicious media files downloaded from the Internet. For those unaware, Codecs is a collection of support libraries that help the Windows operating system to play, compress and decompress various audio and video file extensions. The two newly disclosed security vulnerabilities, assigned CVE-2020-1425 and CVE-2020-1457 , are both remote code execution bugs that could allow an attacker to execute arbitrary code and control the compromised Windows computer. According to Microsoft, both remote code executi

Russian Hacker Gets 9-Year Jail for Running Online Shop of Stolen Credit Cards

Jun 29, 2020
A United States federal district court has finally sentenced a Russian hacker to nine years in federal prison after he pleaded guilty of running two illegal websites devoted to facilitating payment card fraud, computer hacking, and other crimes. Aleksei Yurievich Burkov , 30, pleaded guilty in January this year to two of the five charges against him for credit card fraud—one count of access device fraud and one count of conspiracy to commit access device fraud, identity theft, computer intrusions, wire fraud, and money laundering. Burkov admitted to operating a website named Cardplanet that was dedicated to buying and selling stolen credit card and debit card data for anywhere between $2.50 and $10 per payment card, depending on the card type, origin, and availability of card owner information. According to the U.S. Department of Justice, Cardplanet hosted roughly 150,000 payment card details between 2009 and 2013, most of which belonged to U.S. citizens and used to make over $

'Satori' IoT DDoS Botnet Operator Sentenced to 13 Months in Prison

Jun 26, 2020
The United States Department of Justice yesterday sentenced a 22-year-old Washington-based hacker to 13 months in federal prison for his role in creating botnet malware, infecting a large number of systems with it, and then abusing those systems to carry out large scale distributed denial-of-service (DDoS) attacks against various online service and targets. According to court documents, Kenneth Currin Schuchman , a resident of Vancouver, and his criminal associates–Aaron Sterritt and Logan Shwydiuk–created multiple DDoS botnet malware since at least August 2017 and used them to enslave hundreds of thousands of home routers and other Internet-connected devices worldwide. Dubbed Satori, Okiru, Masuta, and Tsunami or Fbot, all these botnets were the successors of the infamous IoT malware Mirai , as they were created mainly using the source code of Mirai, with some additional features added to make them more sophisticated and effective against evolving targets. Even after the orig

Hackers Using Google Analytics to Bypass Web Security and Steal Credit Cards

Jun 23, 2020
Researchers reported on Monday that hackers are now exploiting Google's Analytics service to stealthily pilfer credit card information from infected e-commerce sites. According to several independent reports from PerimeterX , Kaspersky , and Sansec , threat actors are now injecting data-stealing code on the compromised websites in combination with tracking code generated by Google Analytics for their own account, letting them exfiltrate payment information entered by users even in conditions where content security policies are enforced for maximum web security. "Attackers injected malicious code into sites, which collected all the data entered by users and then sent it via Analytics," Kaspersky said in a report published yesterday. "As a result, the attackers could access the stolen data in their Google Analytics account." The cybersecurity firm said it found about two dozen infected websites across Europe and North and South America that specialized in

Hackers Leaked 269 GB of U.S. Police and Fusion Centers Data Online

Jun 22, 2020
A group of hacktivists and transparency advocates has published a massive 269 GB of data allegedly stolen from more than 200 police departments, fusion centers, and other law enforcement agencies across the United States. Dubbed BlueLeaks , the exposed data leaked by the DDoSecrets group contains hundreds of thousands of sensitive documents from the past ten years with official and personal information. DDoSecrets, or Distributed Denial of Secrets , is a transparency collective similar to WikiLeaks, which publicly publishes data and classified information submitted by leakers and hackers while claiming the organization itself never gets involved in the exfiltration of data. According to the hacktivist group, BlueLeaks dump includes "police and FBI reports, bulletins, guides and more," which "provides unique insights into law enforcement and a wide array of government activities, including thousands of documents mentioning COVID19.

A Bug in Facebook Messenger for Windows Could've Helped Malware Gain Persistence

Jun 11, 2020
Cybersecurity researchers at Reason Labs, the threat research arm of security solutions provider Reason Labs , today disclosed details of a vulnerability they recently discovered in the Facebook Messenger application for Windows. The vulnerability, which resides in Messenger version 460.16, could allow attackers to leverage the app to potentially execute malicious files already present on a compromised system in an attempt to help malware gain persistent/extended access. Reason Labs shared its findings with Facebook in April, after which the social media company quickly patched the flaw with the release of an updated version of Facebook Messenger for Windows users via the Microsoft store. According to researchers, the vulnerable app triggers a call to load Windows Powershell from the C:\python27 path. This path is typically created when installing version 2.7 of the Python and does not commonly exist in most Windows installations. Attackers can hijack such calls that att

Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Jun 10, 2020
Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments (TEE). Called SGAxe , the first of the flaws is an evolution of the previously uncovered CacheOut attack (CVE-2020-0549) earlier this year that allows an attacker to retrieve the contents from the CPU's L1 Cache. "By using the extended attack against the Intel-provided and signed architectural SGX enclaves, we retrieve the secret attestation key used for cryptographically proving the genuinity of enclaves over the network, allowing us to pass fake enclaves as genuine," a group of academics from the University of Michigan said. The second line of attack, dubbed CrossTalk by researchers from the VU University Amsterdam, enables attacker-controlled code executing on one CPU core to target SGX enclaves running on a completely different core, and determine the enclave'
