Yahoo Hacker linked to Russian Intelligence Gets 5 Years in U.S. Prison

May 30, 2018Mohit Kumar
A 23-year-old Canadian man, who pleaded guilty last year for his role in helping Russian government spies hack into email accounts of Yahoo users and other services, has been sentenced to five years in prison. Karim Baratov (a.k.a Karim Taloverov, a.k.a Karim Akehmet Tokbergenov), a Kazakhstan-born Canadian citizen, was also ordered on Tuesday by United States Judge Vince Chhabria to pay a fine of $250,000. Baratov had previously admitted his role in the 2014 Yahoo data breach that compromised about 500 million Yahoo user accounts. His role was to "hack webmail accounts of individuals of interest to the FSB," Russia's spy agency. In November, Baratov pleaded guilty to a total of nine counts, including one count of conspiring to violate the Computer Fraud and Abuse Act, and eight counts of aggravated identity theft. According to the US Justice Department, Baratov and his co-defendant hacker Alexsey Belan worked for two agents—Dmitry Dokuchaev and Igor Sushch
18-Byte ImageMagick Hack Could Have Leaked Images From Yahoo Mail Server

18-Byte ImageMagick Hack Could Have Leaked Images From Yahoo Mail Server

May 23, 2017Swati Khandelwal
After the discovery of a critical vulnerability that could have allowed hackers to view private Yahoo Mail images, Yahoo retired the image-processing library ImageMagick. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The tool is supported by PHP, Python, Ruby, Perl, C++, and many other programming languages. This popular image-processing library made headline last year with the discovery of the then-zero-day vulnerability, dubbed ImageTragick , which allowed hackers to execute malicious code on a Web server by uploading a maliciously-crafted image. Now, just last week, security researcher Chris Evans demonstrated an 18-byte exploit to the public that could be used to cause Yahoo servers to leak other users' private Yahoo! Mail image attachments. 'Yahoobleed' Bug Leaks Images From Server Memory The exploit abuses a security vulnerability in the ImageMagick library, which Evans dubbed

Yahoo! Hack! How It Took Just One-Click to Execute Biggest Data Breach in History

In the digital world, it just takes one click to get the keys to the kingdom. Do you know spear-phishing was the only secret weapon behind the biggest data breach in the history? It’s true, as one of the Yahoo employees fell victim to a simple phishing attack and clicked one wrong link that let the hackers gain a foothold in the company's internal networks. You may be familiar with phishing attacks — an attempt to steal user credentials or financial data — while, Spear-phishing is a targeted form of phishing in which attackers trick employees or vendors into providing remote-access credentials or opening a malicious attachment containing an exploit or payload. Here's how the Yahoo's massive data breach was traced back to human error and who were the alleged masterminds behind this hack. On Wednesday, the US government charged two Russian spies (Dmitry Dokuchaev and Igor Sushchin) and two criminal hackers (Alexsey Belan and Karim Baratov) in connection with the 20

Yahoo Reveals 32 Million Accounts Were Hacked Using 'Cookie Forging Attack'

March 02, 2017Mohit Kumar
Yahoo has just revealed that around 32 million user accounts were accessed by hackers in the last two years using a sophisticated cookie forging attack without any password. These compromised accounts are in addition to the Yahoo accounts affected by the two massive data breaches that the company disclosed in last few months. The former tech giant said that in a regulatory filing Wednesday that the cookie caper is likely linked to the "same state-sponsored actor" thought to be behind a separate, 2014 data breach that resulted in the theft of 500 Million user accounts . "Based on the investigation, we believe an unauthorized third party accessed the company's proprietary code to learn how to forge certain cookies," Yahoo said in its annual report filed with the US Securities and Exchange Commission (SEC). "The outside forensic experts have identified approximately 32 million user accounts for which they believe forged cookies were used or taken

December 16, 2016Mohit Kumar
Recently Yahoo disclosed a three-year-old massive data breach in its company that exposed personal details associated with more than 1 Billion user accounts , which is said to be the largest data breach of any company ever. The new development in Yahoo!'s 2013 data breach is that the hacker sold its over Billion-user database on the Dark Web last August for $300,000, according to Andrew Komarov, Chief Intelligence Officer (CIO) at security firm InfoArmor. Komarov told the New York Times that three different buyers, including two "prominent spammers" and the third, is believed to be involved in espionage tactics paid $300,000 to gain control of the entire database. The hacker group that breached Yahoo and sold the database is believed to based in Eastern Europe, but the company still does not know if this information is accurate or not. Beside full names, passwords, date of births and phone numbers of 1 Million Yahoo users, the database also includes backup em
Yahoo Flaw Allowed Hackers to Read Anyone's Emails

Yahoo Flaw Allowed Hackers to Read Anyone's Emails

December 08, 2016Swati Khandelwal
Yahoo has patched a critical security vulnerability in its Mail service that could have allowed an attacker to spy on any Yahoo user's inbox. Jouko Pynnönen, a Finnish Security researcher from security firm Klikki Oy, reported a DOM based persistent XSS (Cross-Site Scripting) in Yahoo mail, which if exploited, allows an attacker to send emails embedded with malicious code. In his blog post published today, the researcher demonstrated how a malicious attacker could have sent the victim's inbox to an external site, and created a virus that attached itself to all outgoing emails by secretly adding a malicious script to message signatures. Since the malicious code is in the message's body, the code will get executed as soon as the victim opens the boobytrapped email and its hidden payload script will covertly submit victim's inbox content to an external website controlled by the attacker. This issue is because Yahoo Mail failed to properly filter potentially malici

Yahoo Disables Email Auto-Forwarding; Making It Harder for Users to Move On

October 11, 2016Swati Khandelwal
Yahoo! has disabled automatic email forwarding -- a feature that lets its users forward a copy of incoming emails from one account to another. The company has faced lots of bad news regarding its email service in past few weeks. Last month, the company admitted a massive 2014 data breach that exposed account details of over 500 Million Yahoo users. If this wasn't enough for users to quit the service, another shocking revelation came last week that the company scanned the emails of hundreds of millions of its users at the request of a U.S. intelligence service last year. That's enough for making a loyal Yahoo Mail user to switch for other rival alternatives, like Google Gmail, or Microsoft's Outlook. Yahoo Mail Disables Auto-Forwarding; Making It Hard to Leave But as Yahoo Mail users are trying to leave the email service, the company is making it more difficult for them to transition to another email service. That's because since the beginning of Octob

It seems like it is not all over for Yahoo yet. Another day, another bad news for Yahoo! Verizon, which has agreed to purchase  Yahoo for $4.8 Billion , is now asking for a $1 Billion discount, according to recent reports. The request comes after Verizon Communications learned about the recent disclosures about hacking  and spying in past few weeks. Just two weeks ago, Yahoo revealed that at least a half Billion Yahoo accounts were stolen in 2014 hack, marking it as the biggest data breach in history. And if this wasn't enough, the company faced allegations earlier this week that it built a secret tool to scan all of its users' emails last year at the behest of a United States intelligence agency. Due to these incidents, AOL CEO Tim Armstrong, who runs the Verizon subsidiary, is "pretty upset" about Yahoo's lack of disclosure, and is even seeking to pull out of the deal completely or cut the price, the New York Post claimed, citing multiple sources.

Users are still dealing with the Yahoo's massive data breach that exposed over 1 Billion Yahoo accounts and there’s another shocking news about the company that, I bet, will blow your mind. Yahoo might have provided your personal data to United States intelligence agency when required. Yahoo reportedly built a custom software programmed to secretly scan all of its users' emails for specific information provided by US intelligence officials, according to a report by Reuters . The tool was built in 2015 after company complied with a secret court order to scan hundreds of millions of Yahoo Mail account at the behest of either the NSA or the FBI, according to the report that cites three separate sources who are familiar with the matter. According to some experts, this is the first time when an American Internet company has agreed to such an extensive demand by a spy agency's demand by searching all incoming emails, examining stored emails or scanning a small number

500 million accounts — that's half a Billion users! That's how many Yahoo accounts were compromised in a massive data breach dating back to 2014 by what was believed to be a "state sponsored" hacking group. Over a month ago, a hacker was found to be selling login information related to 200 million Yahoo accounts on the Dark Web , although Yahoo acknowledged that the breach was much worse than initially expected. "A recent investigation by Yahoo! Inc. has confirmed that a copy of certain user account information was stolen from the company's network in late 2014 by what it believes is a state-sponsored actor," reads the statement . Yahoo is investigating the breach with law enforcement agency and currently believes that users' names, email addresses, dates of birth, phone numbers, passwords, and in some cases, encrypted and unencrypted security questions-answers were stolen from millions of Yahoo users. However, the company does not believe
