securely, but it was undermined by an SQL injection attack. The cl0p

purloined information on June 14. Qualsys estimates that over half
the sites were patched within 48 hours. Nonetheless, some corporate
and banking giants were affected.

Summary:
Reddit found itself faced with both a user revolt and an extortion
attempt over stolen data after is announced plans to charge third
party app developers for the right to offer the apps on Reddit.
Although the extortion by the Black Cat ransomware gang is based
on credible reports of having previously breached Reddit user's
private data, observers were skeptical about the claims that the
Black Cat gang cared about Reddit's pricing policies. The user
revolt, however, shut down many subreddits.
Summary:
A recent piece of legislation in the UK would require that providers
of end-to-end encryption provide back-door government access, and that
has drawn sharp criticism from Apple and others. Apple had to reverse
its plans to provide such a capability in the US in 2021, and it now
strongly supports the idea that E2E has fundamental importance in
messaging privacy. The UK legislation includes provisions for
prosecuting executives of non-compliant companies, so much is at
stake on both sides of this argument.
Summary:
A zero-day vulnerability in Microsoft authentication led to a breach
of emails for some officials in the US Departments of Justice and
Commerce. Although Microsoft discovered the problem and patched all
customer systems, the incident was ongoing for several weeks. It has
shaken trust in the systems. The problem was caused by a privilege
escalation that let the user of a single compromised account to gain
access to an entire organization's email account. The original
compromised account was probably accessed via a phishing attack.
There is likely to be quite a bit of fallout as the US considers the
ease with which China seems to gain access to government systems.
Summary:
This press release from Microsoft Research has information about the
authentication token forging and the company's response.
Summary:
It's hard to know what to say after "shocking breach of trust". At
least 3 tax filing services have been forwarding sensitive user
data to Facebook and/or Google, and those companies have been using
the data to identify the users and to target advertising at them.
This information "sharing" happened because the companies involved
agreed to add code to their websites that would "improve the user
experience." The result was that much of the data that customers
entered into website forms was relayed to the tech giants where they
felt free to make use of it for purposes far beyond what the tax
companies realized.
Summary:
Facebook pushed back against statements by Senate members condemning
the collection of sensitive taxpayer information. The problems have
been exaggerated, says Facebook, and some of the blame lies with the
tax filing companies for configuring their systems incorrectly.
One suspects this argument is far from over.
Summary:
JumpCloud provides identity management and access control to 5K
customers representing 180K organizations. At some point, recently,
its systems were infiltrated by actors who appeared to have
nation-state capabilities or intentions. An internal investigation
determined that only 5 customers and a few devices were impacted.
Apparently the attack was initiated via spearphishing and was targeted
narrowly. JumpCloud believes that they deflected the attack by
forcing an update of all API keys.
