AlienVault presents OTX Endpoint Threat Hunter, its innovative free endpoint scanning service

Posted: 21 Apr 2018 09:07 AM PDT

Threat intelligence firm AlienVault announced the launch of a free endpoint scanning service, called OTX Endpoint Threat Hunter.

Threat intelligence firm AlienVault announced the launch of a free endpoint scanning service, called OTX Endpoint Threat Hunter, that allows private firms and security experts to identify threats in their networks.

“OTX Endpoint Threat Hunter is a free threat-scanning service in Open Threat Exchange that allows you to detect malware and other threats on your critical endpoints using OTX threat intelligence. This means that you can now harness the world's largest open threat intelligence community to assess your endpoints against real-world attacks on demand or as new attacks appear in the wild—all. for. free.” states the announcement published by AlienVault.

AlienVault OTX Endpoint Threat Hunter

The OTX Endpoint Threat Hunter service is part of the AlienVault Open Threat Exchange (OTX) platform that currently provides more than 19 million threat indicators contributed by over 80,000 users.

This means that users can assess their infrastructure by using threat information collected by the world's largest open threat intelligence community.

OTX Endpoint Threat Hunter is a free threat-scanning service that allows users to detect malware and other threats on endpoints using OTX threat intelligence.

The new service uses lightweight endpoint agent, the AlienVault Agent, that executes predefined queries against one or more OTX pulses, the agent can be installed on Windows, Linux and other endpoint devices.

Each pulse includes a complete set of data on a specific threat, including IoCs.

OTX Endpoint Threat Hunter is directly integrated in OTX, this means that users can start using it without the use of other security tools as explained by AlienVault.

  • If you haven't already, register with the Open Threat Exchange (OTX). It's free to join.
  • Download and install the AlienVault Agent on the Windows or Linux devices* you want to monitor. The AlienVault Agent is immediately ready to find threats.
  • Launch a query on any endpoint from OTX by selecting a pre-defined query that looks for IOCs in one or more OTX pulses.
  • The AlienVault Agent executes the query, and within moments you can view the results of the query display across all your endpoints on a summary page within OTX.

OTX Endpoint Threat Hunter can also be used to scan for processes running without a binary on disk, scan for crypto-mining activity and scan for installed malicious / annoying Chrome extensions.

AlienVault has described several scenarios where Endpoint Threat Hunter can be effective, including:

  • Identify whether your endpoints have been compromised in a major malware attack.
  • Assess the threat posture of your critical endpoints.
  • Query your endpoints for other suspicious activities.

Users can also scan all the endpoints against multiple pulses at once, the OTX Endpoint Threat Hunter allows to scan against pulses as well as YARA rules in multiple ways:

  • Scan all AlienVault-contributed Pulses
  • Scan by all AlienVault-contributed YARA Rules (Linux only)
  • Scan by all pulses you subscribe to (all pulses updated in the last 7 days)
  • Scan by all pulses you subscribe to (all pulses updated in the last 30 days)

Twitter bans Kaspersky from advertising its products through its platform

Posted: 21 Apr 2018 07:54 AM PDT

Twitter bans Kaspersky Lab from advertising its solutions on the platform citing DHS ban for its alleged ties with the Russian intelligence.

Twitter bans Kaspersky Lab from advertising on its platform citing DHS ban for its alleged ties with Russian intelligence agencies.

“At the end of January of this year, Twitter unexpectedly informed us about an advertising ban on our official accounts where we announce new posts on our various blogs on cybersecurity (including, for example, Securelist and Kaspersky Daily) and inform users about new cyberthreats and what to do about them.” reads an open letter sent to the management of Twitter by Kaspersky. “In a short letter from an unnamed Twitter employee, we were told that our company "operates using a business model that inherently conflicts with acceptable Twitter Ads business practices."

According to Twitter, this is a policy decision anyway the social media allows Kaspersky Lab to remain an organic user on the platform in accordance with his Rules.

Twitter bans Kaspersky

In September, the US Department of Homeland security banned government agencies for using software products developed by Kaspersky Labs. The ban was the response to the concerns about possible ties between Kaspersky and Russian intelligence agencies.

According to The Washington Post, which first reported the news, the order applies to all civilian government networks, but not the military ones.

In July, the US General Services Administration announced that the security firm Kaspersky Lab was deleted from lists of approved vendors.

The US government banned Kaspersky solutions amid concerns over Russian state-sponsored hacking.

In September, US Homeland Security issued a Binding Operational Directive that orders agencies to remove products developed by Kaspersky Lab within 90 days.

The Twitter’s decision is directly linked to the ban, it is the first social media platform to adopt this line against the security giant.

In October, both Best Buy and Office Depot decided to stop the sale of Kaspersky products due to the US ban.

In response to the ban, Kaspersky has repeatedly denied the accusations and it announced the launch of a Global Transparency Initiative that involves giving partners access to the source code of its solutions.

Eugene Kaspersky is disappointed for this decision as stated in the open letter.

“Huh? I read this formulation again and again but still couldn't for the life of me understand how it might relate to us. One thing I can say for sure is this: we haven't violated any written – or unwritten – rules, and our business model is quite simply the same template business model that's used throughout the whole cybersecurity industry: We provide users with products and services, and they pay us for them.” continues the letter. “What specific (or even non-specific) rules, standards and/or business practices we violated are not stated in the letter. In my view, the ban itself contradicts Twitter's declared-as-adopted principle of freedom of expression. I'll return to that point in a minute, but first let's look at the others:”

Back to the Twitter ban, Kaspersky announced that it will donate this year’s Twitter advertising budget to the Electronic Frontier Foundation.

“By the way, if you think we're doing this simply to get our advertising back – you're wrong. There are many other ways to get information to interested parties. Which got me thinking…” concluded the letter.

“No matter how this situation develops, we won't be doing any more advertising on Twitter this year. The whole of the planned Twitter advertising budget for 2018 will instead be donated to the Electronic Frontier Foundation (EFF). They do a lot to fight censorship online.”

Attackers Fake Computational Power to Steal Cryptocurrencies from equihash Mining Pools

Posted: 21 Apr 2018 06:07 AM PDT

Security experts at 360 Core Security have recently detected a new type of attack which targets some equihash mining pools.

After analysis, they found out the attacked equihash mining pools are using a vulnerable equihash verifier

(equihashverify : https://github.com/joshuayabut/equihashverify) to verify miners' shares.

There is a logic vulnerability in this verifier, so attacker can easily fake mining shares which can bypass the equihash solution verifier without using so much computing power.

This vulnerability has a wide impact because the verifier (equihashverify) is previously used by the Zcash official open source mining pool (node-stratum-pool), and many new cryptocurrencies which use equihash as PoW algorithm are forked from this pool.

Equihash is a memory-oriented Proof-of-Work algorithm developed by the University of Luxembourg's Interdisciplinary Centre for Security, Reliability and Trust (SnT).

The cryptocurrency ZCash integrated Equihash in April 2016, for reasons such as security, privacy, and ASIC miner resistance.

According to the CryptoLUX scientists, the algorithm permits avoiding centralization of the mining process in the hands of a few first-class miners with specialized mining hardware, thus contributing to the "democratization" of digital currencies based on Equihash.

equihash mining pools

Running Equihash will use quite a lot of memory which means how much you can mine depends on the volume of your computing memory. This makes it impossible to customize a low-cost mining hardware in a short time.

The vulnerability in this report is not a vulnerability of Equihash, but a vulneranility of the implementation of Equihash solution verifier. Here is the detail:

In file equi.c, we can find the function bool verifyEH(const char *hdr, const char *soln). The parameter hdr stands for the blockheader and the parameter soln={x1,x2,…,x512} stands for the user summited solution for Equihash.

The algorithm computes:

Vhash=hash(hdr,x1)^ hash(hdr,x2) ^…^. hash(hdr,x512);

The next step is to check if all the returned values in Vhash are zeros. If they all equal to zero, return true.

If not, return false. It seems to be feasible; however, things are different in reality because there are multiple vulnerabilities in the algorithm.

The simplest one is that the function does not check whether xi is duplicated. So, if the attacker provides a solution with {x1=1,x2=1,x3=1,…,x512=1}, then he can bypass the equihash verifier for any blockheader.

Node-stratum-pool has changed the dependency of Equihashverify to a zencash official equihashverify (https://github.com/zencashofficial/equihashverify.git). However, many other smaller cryptocurrencies and mining pools haven't updated their dependencies yet. Attacks are happening in the wild, so please update yours in time.

The simple POCs are following:

var ev = require('bindings')('equihashverify.node');

UK Teenager Kane Gamble who hacked CIA Chief and other US intel officials gets 2-year jail sentence

Posted: 21 Apr 2018 01:08 AM PDT

UK teenager Kane Gamble (18) who broke into the email accounts of top US intelligence and security officials including the former CIA chief John Brennan. was sentenced to two years in prison.

The British hacker Kane Gamble (18) who broke into the email accounts of top US intelligence and security officials including the former CIA chief John Brennan. was sentenced to two years in prison on Friday.

The Gamble shared some of the material he stole from its victims to WikiLeaks.

The British teenager from Coalville, Leicester, was arrested at his home on February 9, 2017, in October, he admitted in a British court to have attempted to hack into the computers of top US officials.

Kane Gamble pleaded guilty to ten charges related to the attempted intrusions occurred between late 2015 and early 2016.

The teenager pleaded guilty to eight charges of performing a function with intent to gain unauthorized access, and two charges of unauthorized acts with intent to compromise the operation of a computer.

Gamble targeted the US Department of Justice and many other senior American security officials from his home in the East Midlands region of England.

The list of targeted officials is long and includes James Clapper, the Director of National Intelligence under President Obama's administration and the deputy director of the FBI Jeh Johnson.

The hacker was suspected to be the founder of the hacker group  'Crackas With Attitude' that targeted the US officials between October 2015 and February 2016.

In October, the teenager has been released on conditional bail ahead of sentencing on December 15.

Kane Gamble was sentenced to two years in jail and will serve the sentence in a youth detention facility.

“This was an extremely nasty campaign of politically motivated cyber terrorism,” said judge Charles Haddon-Cave in the London criminal court.

“The victims would have felt seriously violated,” 

“It also seems he was able to successfully access Mr Brennan’s iCloud account,” prosecutor John Lloyd-Jone said earlier. 

Kane Gamble also gained access to the network of the US Department of Justice and was able to access court case files, including on the Deepwater oil spill.

Gamble's advocate sustained that Gamble he is on the autism spectrum at the time of his offending had the mental development of a teenager.

According to the prosecutor, The teenager claimed he acted to support the Palestinian cause, and due to the United States “killing innocent civilians.”

Two other members of Crackas With Attitude team, Andrew Otto Boggs and Justin Gray Liverman, were arrested by FBI in September 2016 and had already been sentenced to five years in federal prison.
