Slack Discloses in SEC Filings That it’s a Target for Malicious Attacks

Slack discloses in sec filings that it’s a target for malicious attacks

Ahead of one of the most anticipated initial public offerings (IPOs) of 2019, Slack Technologies Inc. in its filings with the US Securities and Exchange Commission (SEC), warned investors that it’s a prime target for nation-scale hacking groups. This according to a report by Motherboard, published April 26, 2019.

A Prime Target for Data Thieves

San Francisco-based software company Slack’s SEC filings suggest that the company is expecting malicious cyber attacks from “sophisticated organized crime, nation-state, and nation-state supported actors.”

Per Slack’s S-1 securities registration form filed with the SEC, the $7.1 billion corporate believes it could face threats from organized crime and nation-state actors. According to the document, the company could be targeted by “traditional computer hackers” via malware, viruses, ransomware, phishing, credential stealing, and denial-of-service attacks.

It’s worth highlighting that the document doesn’t claim that such attacks have actually happened. Rather, it only identifies threats from these bad actors as an active risk to the company.

The company in its S-1 filing also mentioned that its data was breached in March 2015. During the four days long attack, an unidentified person or a group of persons had uninterrupted access to Slack’s data repository which included user names, email addresses, encrypted passwords, and other confidential information.

Soon after this incident, the company introduced two-factor authorization (2FA) to bolster its service’s security measures.

A $16 Billion Giant

Interestingly enough, Slack hasn’t yet implemented end-to-end encryption for messages. This means that third-parties can easily download and read an individual’s entire Slack history without their permission or knowledge.

It also means that anything said on Slack could be held against a person in court.

Notably, the workplace-messaging company recently reported a net loss of $139 million which has raised a few eyebrows on Wall Street. The company, planning to go public through an unusual listing route, revealed that it incurred a net loss of $139 million for the year ending January 31, 2019. Slack reported $140 million net loss for the corresponding period of the previous year.

Further, the company’s Class B shares have also been changing hands in private markets for as much as $23.41 in 2019 through January.

According to data gathered by Bloomberg, Slack’s shareholders have sold stock at prices as high as $25 or $26 a share, which has investors estimating its market valuation at almost $16 billion.

Adam Back to Jihan Wu: SegWit Not ‘Complicated,’ Fixes Satoshi’s Bug

Hashcash inventor Adam Back has said Segregated Witness (SegWit) “fixes” an original bug in bitcoin from creator Satoshi Nakamoto.


Back: SegWit ‘Fixes Satoshi Bug’

As part of a Twitter exchange Friday, Back rebuffed criticism from bitcoin Unlimited proponent Jihan Wu, demonstrating how SegWit is beneficial to the virtual currency’s core protocol.

Wu, who is a co-founder of mining conglomerate Bitmain, had said that the technology would make the network “more complicated.”

“SegWit is not more complicated,” Back wrote.

“It fixes Satoshi’s bug that txid=H(tx,sig) to txid=H(tx) this is not complicated, and it is necessary to fix.”

What’s more, if implemented, SegWit can can actually help reduce the so-called “technical debt” burden of complicated code albeit having its own tradeoffs, which are assessed here.

The segwit code has been heavily reviewed, which helps resist the introduction of technical debt at both a code and design level…Segwit has multiple independent reimplementations, which helps discover any unnecessary complexity and technical debt at the point that it can still be avoided.

SegWit: Complicated & Straightforward

Wu’s stance echoes a broader opinion from the Chinese community in particular that SegWit creates unnecessary complexity within bitcoin.

In an interview with Bitcoinist this month, for example, Leon Liu, CEO of P2P trading service Bitkan, said that this was a reason why the technology “is not the best solution for bitcoin scaling.”

“Segwit will not be the best solution for bitcoin scaling, it will make the bitcoin network more complicated,” he stated.

At the same time, efforts have been made to allay such fears, Blocktrail CTO Ruben De Vries commenting last year that SegWit “is not very complicated if you already know the ins and outs of the bitcoin protocol.”

Back meanwhile has praised attempts at educating the wider community on the nature of scaling solutions without resorting to ‘political’ siding.

An explainer on SegWit by Andreas Antonopoulos garnered considerable praise, Back describing it as “the best he’d seen on the topic.”

On its benefits, Antonopoulos wrote in the blog post, which originally came out in August last year:

“Firstly, segregated witness reduces the overall cost of transactions by discounting witness data and increasing the capacity of the bitcoin blockchain.

“Secondly, segregated witness’ discount on witness data corrects a misalignment of incentives that may have inadvertently created more bloat in the UTXO set.”

Litecoin Bounce on SegWit Rumors?

SegWit is traditionally considered ‘complicated’ compared to merely increasing the bitcoin block size, despite the latter requiring a hard fork of the virtual currency.

Currently, the proposal is still behind bitcoin Unlimited though both need at least 95% to activate.

Outside the bitcoin debate, rumors surfacing that Litecoin is to activate SegWit may have led to a surprise expansion in value of the altcoin by around 30%.
